Problems solved by technology

These methods have several major problems: First, they can only target small areas of farmland, and cannot cover large areas of frozen
Second, low efficiency
Most of the energy is wasted by ineffective consumption during the conversion process, resulting in higher costs
Third, high water use may affect the quality of crops
Fourth, a large amount of soot blown out by burning wood will pollute the surrounding environment
First of all, too high transmission power will harm the farmers who push the cart; secondly, the field that the device can implement must be suitable for the trolley to move between the plants; moreover, the device cannot continue to heat. The temperature will drop soon, and the actual effect of preventing frostbite will not be achieved.
At the same time, the invention also proposes a solution to directly install the transmitter above each plant, but this method is more expensive and lacks practical possibility

Embodiment 1

[0045] In a relatively flat, large-scale farm tea garden, it is advisable to choose a multi-directional plate antenna 4 or a rotating antenna 6, and install a wireless microwave transmitting device fixedly. The advantage is that the microwave coverage area around the antenna is large, the response is fast, and it can be turned on and off at any time; however, it is not flexible enough to be installed and used at a fixed point. It is difficult to achieve average coverage of signal strength during use, and multiple transmitters can be used to cross coverage to overcome this defect, such as Figure 4 shown. In order to ensure a uniform signal, each transmitter needs to be debugged and coordinated before being fixed, and it is suitable to use multiple transmitters when the ambient temperature is low.

[0046] like figure 2 The shown multi-directional plate antenna 4 is fixed on the top of the wireless microwave transmitter 3. A multi-directional microwave transmitting antenna c...

Embodiment 2

[0049] When the farm area is small or scattered, or exists in the form of terraced fields, mountains, etc., the leaky coaxial cable antenna 8 proposed in the present invention can be used in this case.

[0050] The leaky coaxial cable antenna 8 does not adopt permanent fixed installation. After being connected from the wireless microwave transmitter 3, it is temporarily fixed overhead or directly discharged on the ground of the farm according to the different heights and terrain distribution of the crops. Since the cable is made of soft material, the wireless microwave can be flexibly covered on the crops with complex terrain by using this cable antenna, which not only satisfies the uniform wireless microwave coverage of the crops, but also ensures that the wireless microwave is not wasted. like Figure 9 As shown, but because the leaky coaxial cable antenna 8 has a certain length, the wireless microwave signal will weaken as the transmission distance increases, and the surrou...

Abstract

The invention discloses a green agriculture microwave anti-freezing system, which comprises a control module and a plurality of wireless microwave emitting devices, wherein the control module comprises an environment sensor and an environmental power central processor; each microwave emitting device mainly comprises a wireless microwave emitter and a wireless microwave emitting antenna; the heating frequencies of emitted microwaves are at an S band and are 2.4-2.5 GHz, and the central wavelength is 0.122 meter; and the environment sensor, the environmental power central processor, the wireless microwave emitters and a power supply are connected through circuits. A multi-direction plate type antenna, a rotary antenna or a leakage coaxial cable antenna can be selected according to different using requirements. The microwave frequency and the emitting power are adjusted synchronously according to detected real-time data, so that different antenna systems can be selected according to different environment factors, different optimal growing frequencies are selected for different crops, the system advantages of timeliness, accuracy and adaptability are shown fully, and the economical aims of low energy consumption, low radiation and high efficiency are fulfilled.

Description

technical field [0001] The invention relates to a heating system, and relates to a functional electronic technology using wireless microwave heating for crops, specifically referring to a green agricultural microwave antifreeze system capable of preventing spring cold (flash freezing). Background technique [0002] China is a big country in the production, sales and export of agricultural products. However, due to global climate anomalies, extreme cold damage has often occurred in various provinces and cities in recent years. In particular, the sudden low temperature at the beginning of the year and the cold spring caused many crops with high economic value to be frostbitten or frozen to death, resulting in a large-scale reduction in crop production, especially the green belts around important tourist attractions and urban landmarks, which suffered economic losses. It has been multiplied even more. [0003] At present, most antifreeze measures in agriculture are limited to...
