Alleviate the difficulty of docking production and marketing, and promote agricultural products to leave the village
Internet plus adds new vitality to agriculture.

On July 2nd, the State Council held a routine briefing on the State Council’s policies, introducing the related situation of further promoting "Internet+agriculture" to promote the integration and development of rural primary, secondary and tertiary industries. Qu Dongyu, Vice Minister of Agriculture and Rural Affairs, Keke, Director of Market and Economic Information Department of Agriculture and Rural Affairs, and Zong Jinyao, Director of Agricultural Products Processing Bureau attended the meeting and answered questions from reporters.

Qu Dongyu introduced that in the next step, the Ministry of Agriculture and Rural Affairs will promote the project of "internet plus" agricultural products leaving the village, carry out the project of "information entering the village and entering the household" in depth, organize the national training of farmers’ mobile phone application skills, continue to run the "double innovation and double innovation" Expo, promote the in-depth development of mass entrepreneurship and innovation in rural areas, expand the scale, scope and content of regional experiments of agricultural Internet of Things, build big data of the whole industrial chain of important agricultural products, do a good job in monitoring and early warning of agricultural information, and promote the integrated development of rural primary, secondary and tertiary industries

Grasp the standardization of agricultural products and guide production and sales with big data.

"The top priority of’ Internet+Agriculture’ is to promote agricultural products out of the village." Qu Dongyu said that the Ministry of Agriculture and Rural Affairs will help farmers to sell high-quality, qualified and distinctive agricultural products to cities. This requires us to work with relevant departments to formulate policies, including traceability and standardization of the quality and safety of agricultural products, grading packaging and cold chain logistics, to ensure that agricultural products leave the village and can be sold at a good price.

"China is a big country with small farmers. How to connect with the big market, the Internet provides a rare historical opportunity and means." Qu Dongyu said that the Ministry of Agriculture and Rural Affairs will cooperate with the village-leaving project to help agricultural products from poor areas and other distinctive areas connect with hundreds of millions of small farmers in the big market, and work with relevant departments to issue guidance on agricultural products leaving the village as soon as possible.

The difficulty of unsalable agricultural products has been puzzling the development of agriculture and the increase of farmers’ income in recent years. "Standardization and grading pretreatment of agricultural products are prerequisites for realizing transactions." Qu Dongyu said that in recent years, the Ministry of Agriculture and Rural Affairs has been focusing on the construction of wholesale markets for agricultural products and improving the standard level of wholesale markets. At the same time, the construction of regional brand, enterprise brand and product brand of agricultural products has also been carried out.

"Agricultural and rural big data is massive. We should provide authoritative government information services and useful business information services through data collection, collation, development and utilization." Qu Dongyu introduced that the Ministry of Agriculture and Rural Affairs has organized 21 provinces and cities to carry out big data experiments on eight major agricultural products, improve the monitoring and early warning system, publish the wholesale price index of agricultural products every day, publish the market supply and demand report of 19 agricultural products and the supply and demand balance table of five products every month, and gradually realize the use of data management services to guide production and sales.

Establish a beneficial agricultural information society to open up the digital gap between urban and rural areas

"One embodiment of the urban-rural gap and dual structure is the digital divide between urban and rural areas." Keke pointed out that in view of this difficulty and pain point, the Ministry of Agriculture and Rural Affairs, on the basis of summing up the experience of "12316 agriculture, countryside and farmers information service hotline", implemented the project of information entering villages and households. At present, the whole province has been promoted in 18 provinces. There are 204,000 villages in China that have set up information clubs for farmers, accounting for 1/3 of the administrative villages in the country, which mainly provide public welfare services, convenience services, e-commerce and training experience.

Through the system of province as the core, city and county as the link and village as the node, the information service network covering the people, new agricultural business entities and agricultural socialized service organizations has been established, which can effectively improve rural governance.

In the next step, the Ministry of Agriculture and Rural Affairs will speed up the construction of the information society for benefiting farmers and ensure that more than 80% of the administrative villages in the country will be covered by 2020. Strengthen the training of selecting and appointing village-level information officers, give priority to selecting and appointing information officers from those who return to the countryside and rural youth who are interested in information services, and carry out training and enhance their abilities. Improve the construction and operation mechanism, mobilize the participation enthusiasm of enterprises and other social forces, and achieve sustainable development. Strengthen departmental cooperation, gather information resources related to agriculture, build a public service platform, and improve the service function and level of Yi Nong Information Society.

Grasp industrial integration and upgrade agricultural and rural economy

"In the past, agriculture was focused on agriculture, and farming was carried out on the farming industry, without linking processing, circulation and sales." Zong Jinyao believes that "internet plus" can use market demand and consumption information to guide production, processing and circulation, enhance the interconnection of primary, secondary and tertiary industries, and at the same time introduce the concept and technology of "internet plus" into agriculture, promote the deep integration of agriculture and other industries, and build an upgraded version of agricultural and rural economy.

Qu Dongyu said that in recent years, the Ministry of Agriculture and Rural Affairs has organized nine provinces to carry out regional trials of agricultural Internet of Things, and issued 426 technologies and application models of agricultural Internet of Things products to save costs and increase efficiency. In the cotton field planting of Xinjiang Production and Construction Corps, the Internet of Things technology is integrated and applied, and the comprehensive application benefits increase 210 yuan per mu. At the same time, agricultural and rural e-commerce has developed rapidly, and new formats have flourished. By the end of 2017, the comprehensive demonstration of e-commerce in rural areas had supported 756 counties, the retail sales of rural networks reached 1.25 trillion yuan at the end of last year, and the e-commerce of agricultural products was moving towards the 300 billion yuan mark, driving the number of employed people to exceed 28 million.

Since 2015, the Ministry of Agriculture and Rural Affairs has organized and implemented the subsidy policy for the integration development of the first, second and third industries. So far, it has arranged a total of 12.1 billion yuan to support the integration development projects. In 2017, the output value of China’s agricultural product processing industry reached 22 trillion yuan, and the business income of leisure agriculture and rural tourism reached 740 billion yuan. Various new formats and models such as creative agriculture, sharing agriculture and e-commerce emerged one after another.

In the next step, the Ministry of Agriculture and Rural Affairs should continue to implement the promotion action of rural industrial integration development: implement policies to guide integration, promote the implementation of support policies such as finance, finance, taxation, scientific and technological talents, land use and electricity consumption, support a number of counties, towns and villages, develop rural integration development pilot areas and demonstration parks, and cultivate integrated development enterprises; Develop industrial support and integration, encourage the development of breeding, processing and circulation, leisure tourism, e-commerce, healthy old-age care, health preservation and other industries, and build a rural industrial system; Improve the mechanism to drive integration, guide enterprises and farmers to improve the interest linkage mechanism through order agriculture and share dividends, and provide strong support for rural revitalization.

[Truck House Draft] Nowadays, parking air conditioners are more and more recognized by card friends, but the high cost of modification and the common shortcomings of parking air conditioners make many people discouraged. This article will continue with the last article, "Air conditioning the cab, the truck driver is a professional! ",from the principle of parking air conditioning, modification methods, modification costs, optimization measures, etc.

The parallel parking air conditioner is actually a self-modified form of the original parking air conditioner of the high-equipped model, which is basically similar in form and exactly the same in principle, so card friends don’t have to worry about the problem that the service life of this form of modification is not as good as other modified forms.

Here, let me talk about the principle of automobile air conditioning. In fact, it means that the refrigerant circulates in the air conditioning system, and the evaporator of the refrigerant in the cab changes from liquid to gas, which reduces the temperature in the cab. In the condenser, it is cooled by high-temperature and high-pressure gas and converted into liquid state, thus taking heat out of the cab to the outside of the cab.

The core of automobile air conditioning is the compressor, which plays a role in promoting the whole refrigerant cycle. Therefore, the most important parts of the whole air conditioning system are the evaporator inside the cab, the condenser outside the cab and the compressor. In fact, the air conditioning system is a relatively independent system. As long as the refrigerant circulation is promoted, the air conditioning system can operate normally.

Parallel parking air conditioning is to connect an electric compressor and an air conditioning compressor in parallel to the air conditioning system, so that the refrigerant can be circulated by the air conditioning compressor when it is running, or by the electric compressor when the engine stops running.

The principle is very simple. The next step is to buy accessories and modify the air conditioning system. What is needed is a 24V electric compressor, two three-way valves, two one-way valves, and several air conditioning pipelines …

The first step is to find a suitable position to fix the electric compressor. It is best to be near the frame (that is, the girder) of the automobile compressor. It is suggested to burn a simple bracket with steel plate, fix the bracket on the frame with bolts, and cushion the rubber in the middle for shock absorption. It must not be directly welded to the frame, which will have an impact on the frame.

Then the electric compressor is fixed on the frame by bolts, and a little rubber is also padded in the middle, which can not only reduce vibration, but also prolong the service life of the electric compressor. Note that the installation space must be large enough, otherwise the cab may be perforated and the air conditioning system may be damaged due to vibration and friction at the bottom of the cab when the car is running.

Step 2, discharge the refrigerant. Clean the refrigerant with a refrigerant filling instrument, cut the high-pressure pipe near the automobile air-conditioning compressor at about 30-50 cm, and cut the low-pressure pipe near the air-conditioning compressor at 30-50 cm.

Step 3, parallel pipelines. Connect the cut low-pressure pipeline, the low-pressure pipeline of automobile compressor and the low-pressure pipeline of electric compressor with a tee, and the joint must be tied tightly, then arrange the pipeline and bind it on the frame. A one-way valve is connected to the high-pressure pipeline of the automobile air-conditioning compressor, so that the refrigerant can only flow out from the high-pressure end of the automobile air-conditioning compressor and cannot flow backwards.

Similarly, the high-pressure end of the electric compressor is also connected with a one-way valve. Similarly, only the refrigerant can flow out from the high-pressure end of the electric air-conditioning compressor, and it cannot flow backwards. Be sure to see the direction of the one-way valve clearly when installing, otherwise it will damage the air conditioning system when using it later.

Finally, a tee is used to connect the high-pressure pipe from the compressor with the high-pressure pipe from the electric compressor and the high-pressure pipe to the condenser. At this point, the connection on the refrigeration pipeline is finished. Finally, wrap the pipeline, check whether there is interference in the pipeline and so on.

Step 4, install the condenser fan. For most of them, the air-conditioning condenser is usually in front of the water tank, and the heat dissipation of the air-conditioning condenser depends on the fan of the engine. However, when the parking air conditioner is used, the engine is not running, so an electronic fan must be installed. Some or some models have an electronic fan integrated on the condenser, and this step can be omitted. Just find out the power cord of the electronic fan. At present, there are electronic fans supporting the condensers of various models on the Internet. Generally, the condensers can be installed at a distance of 7CM from the mask.

The fifth step is the connection of electrical wiring. At present, the electric air-conditioning compressors purchased online are generally full frequency conversion. In addition to the electric air-conditioning compressors, they are also equipped with frequency conversion modules, control modules, etc. The wiring is generally complicated, and everyone only needs to wire them according to the schematic diagram.

I won’t talk about the control and the wiring of the frequency conversion module. Every product is different. The main point here is that the power cord of the electric compressor must be thicker, because this power is relatively large, and a conductor with a larger cross-sectional area is needed.

For the motor of evaporator and condenser, we must find the power cord, which is the key to determine the normal operation of evaporator and condenser. The better the heat dissipation of condenser, the better the cooling effect of refrigerant and the cooler the cab.

As for the modification cost, I showed it to the card friends online. If I buy a package, the price is basically around 2700, including an integrated inverter compressor, tee, tee with two check valves, condenser fan, controller and some accessories.

Here, I suggest that you buy it separately. The integrated inverter compressor is about 1600-1800 yuan, the condenser fan is generally within 150 yuan, the tee joint and the tee joint with two one-way valves and other pipeline fittings are 200 yuan, and the parking intelligent air conditioner controller is about within 150 yuan, plus the modification fee of the air conditioner master 300 yuan. The total modification is about 2500 yuan.

After the parking air conditioner is installed, we need to calculate how long a group of batteries can support the parking air conditioner.

For example, let’s take an air conditioning system with an electric compressor with an input power of 800 watts and a refrigeration capacity of about 2,000 watts as an example. In addition, there are two condensing fans with an input power of 120 watts each and an evaporator motor of 80 watts, that is, the total power reaches 1,120 watts. We calculate it as 1,100 watts. A set of batteries in 24V220A stores 5280W*H, and deep discharge of batteries is strictly prohibited, which will accelerate the aging of batteries. Generally, we can only use 70% of the power, that is, 3696W*H at most. 3696W*H divided by 1100W is about 3 hours. Because of the frequency conversion technology adopted by electric compressor, it can be used for about 4 hours.

The biggest disadvantage of parking air conditioner is that it can’t be used for a long time. In order to solve the power problem, I have two schemes.

The first plan is to add a set of batteries. The two batteries of 220A are almost 3,000 yuan, which is a bit expensive, and most people can’t afford it. Moreover, a battery bracket should be fixed on the frame. I don’t really recommend this plan.

The second option is to buy a 24V gasoline or diesel generator, and the price is about 1200 yuan. After installing the low-voltage control circuit, the generator can automatically start when the battery is low and charge the battery. When the battery is full, the generator will automatically stop, which not only avoids the deep discharge of the battery and damages the battery, but also avoids the long-term operation of the generator and the noise disturbing the people.

The author believes that the perfect modification method of parking air conditioner at present is what the appeal said. By connecting the electric air conditioner compressor in parallel with the original air conditioning system, supplemented by the automatic start-stop generator, the dream of blowing the air conditioner as long as you want can be achieved at low cost.
