Description

Technical Field

[0001] The present invention relates to an environment detection device, in particular to an environment detection device for agricultural planting applied in the field of agricultural detection technology. Background Art

[0002] In the process of agricultural planting, air humidity is an extremely critical environmental factor, which has an important impact on the growth, development, occurrence of pests and diseases, and irrigation decisions of crops. Therefore, it is necessary to regularly check whether the air humidity is within the range suitable for crop growth.

[0003] The invention patent with publication number CN118670460B discloses a temperature and humidity detection device for agricultural use. In the invention, a ventilation pipe is connected to the end of the air inlet, and filter plates and buffer components are installed in the ventilation pipe to intercept the airflow, slowing down the airflow velocity in the ventilation pipe, so that the airflow velocity in the ventilation pipe tends to be flat to increase the average time that the airflow stays in the detection box, so that the airflow can be fully blown from the ventilation pipe into the second detection box so that the internal louver box is in contact with the airflow, making the detection result more accurate.

[0004] The invention patent with publication number CN117589235B discloses a temperature and humidity detection device for agricultural planting. In this invention, the temperature and humidity monitoring device can realize two detection modes. One is the fixed-point detection mode, that is, in this mode, the installation position of the temperature and humidity monitoring device is fixed, and the temperature and humidity around the installation point can be stably monitored and detected. The second is the range detection mode. In this mode, the temperature and humidity monitoring device can move up and down autonomously within a certain range, so that the temperature and humidity within the corresponding range can be monitored and detected during the movement.

[0005] The air in the farmland environment will inevitably contain impurities such as dust, especially the farmland on both sides of the road. In the existing technology, when detecting whether the air humidity is within the range suitable for crop growth, humidity sensors are usually used for detection. Dust is easy to adhere to the sensor or enter the sensor, resulting in the accuracy and reliability of the detection results being affected.

[0027] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0028] The first implementation method:

[0029] Figure 1-Figure 4An agricultural planting environment detection device is shown, including a support frame 101, a support plate 102 is fixedly mounted on the support frame 101, an environmental detection intelligent controller 003 and two extraction ratio moisture detection components are fixedly mounted on the support plate 102, the extraction ratio moisture detection component includes a moisture detection sealing cylinder 201 fixedly mounted on the support plate 102, the end of the moisture detection sealing cylinder 201 away from the support plate 102 is connected to a moisture detection air duct 202, a horizontal electric push rod 203 is fixedly mounted in the moisture detection sealing cylinder 201, the output end of the horizontal electric push rod 203 is fixedly connected to a piston plate 204, an annular connecting ring groove 205 is provided on the inner wall of the moisture detection air duct 202, a support ring 206 connected to the connecting ring groove 205 in a sliding and sealing manner is arranged in the connecting ring groove 205, and the support ring 206 is A matching moisture detection and breathable net 207 is fixedly installed on the inner wall. The two moisture detection and breathable nets 207 in the two extraction ratio moisture detection components are made of water-absorbing material and hydrophobic material respectively. A pressure sensor 208 is fixedly installed on the inner wall of the bottom end of the connecting ring groove 205. The bottom end of the support ring 206 is against the pressure sensor 208. The environmental detection intelligent controller 003 is provided with a detection setting module, a moisture detection control module, a comparison and analysis module, and a remote alarm module. The detection setting module is signal-connected with the moisture detection control module and the comparison and analysis module. The moisture detection control module is signal-connected with the horizontal electric push rod 203 and the pressure sensor 208. The pressure sensor 208 is signal-connected with the comparison and analysis module, and the comparison and analysis module is signal-connected with the remote alarm module.

[0030] A pressure threshold interval is reasonably set through the detection setting module, and a detection cycle is set through the detection setting module. The humidity detection control module will regularly control the two extraction ratio humidity detection components to detect whether the air humidity is normal (that is, whether the air humidity is within a range suitable for crop growth) according to the detection cycle. During the detection, the humidity detection control module will start the pressure sensor 208 (when the humidity detection control module controls the pressure sensor 208 to perform the corresponding operation, it will control the pressure sensors 208 in the two extraction ratio humidity detection components to perform the same operation at the same time, and the same is true when the humidity detection control module is controlled below), so that the pressure sensor 208 detects the pressure it is subjected to at this time, and the pressure sensor 208 The pressure data detected by 08 will be transmitted to the comparison and analysis module, and then the humidity detection control module will start the horizontal electric push rod 203, so that the horizontal electric push rod 203 pulls the piston plate 204 to move a certain distance away from the humidity detection air pipe 202 (the moving distance can be set by the detection setting module), and the movement of the piston plate 204 will inhale a certain amount of air into the humidity detection sealing cylinder 201 through the humidity detection air pipe 202. Then, the humidity detection control module will control the pressure sensor 208 to perform pressure detection again, so that the comparison and analysis module can determine whether the air humidity is normal by analyzing the pressure data detected twice by the two pressure sensors 208 and the pressure threshold range;

[0031] For ease of description, the moisture-detecting breathable net 207 made of water-absorbing material is recorded as A, and the moisture-detecting breathable net 207 made of hydrophobic material is recorded as B. The two sets of pressure data corresponding to A are recorded as A1 and A2, and the two sets of pressure data corresponding to B are recorded as B1 and B2. When air flows through A and B respectively, the same thing is that both A and B will intercept dust in the air, and because the two extraction and moisture-detecting components are in the same environment, the amount of dust intercepted by A and B will be almost equal. The difference is that A will absorb moisture in the air, but B will not. The comparison and analysis module can calculate according to the pressure data detected by the pressure sensor 208 to calculate the value of (A2-A1)-(B2-B1). The greater the air humidity, the more moisture A absorbs, and the larger the calculation result. The smaller the air humidity, the less moisture A absorbs, and the smaller the calculation result. Therefore, the calculation result can reflect the air humidity. The comparison and analysis module compares the calculation result with The pressure threshold interval is compared. If the calculation result is within the pressure threshold interval, it means that the air humidity is normal. If the calculation result is not within the pressure threshold interval, it means that the air humidity is abnormal. Therefore, the comparison and analysis module can determine whether the air humidity is normal by analyzing the pressure data detected twice by the two pressure sensors 208 and the pressure threshold interval. When the judgment result is that the air humidity is abnormal, the comparison and analysis module will control the remote alarm module to alarm relevant personnel (the alarm method can be SMS, email, etc., and the remote alarm is a mature existing technology, which will not be described here. In addition, when the alarm is issued, the remote alarm module will also send the calculation result of the comparison and analysis module to the relevant personnel). After the detection is completed, the humidity detection control module will turn off the pressure sensor 208 and control the horizontal electric push rod 203 to push the piston plate 204 to reset. When the horizontal electric push rod 203 pushes the piston plate 204 to reset, the dust intercepted by the moisture detection breathable net 207 can be blown out of the moisture detection air duct 202;

[0032] Therefore, the environmental detection device in the present application can effectively eliminate the interference of impurities such as dust when detecting whether the air humidity is within a range suitable for crop growth, thereby effectively improving the accuracy and reliability of the detection results. When abnormal air humidity is detected, it can promptly alert relevant personnel, prompting relevant personnel to take corresponding measures in a timely manner, thereby ensuring the growth and development of crops, greatly improving the practicality and functionality of the detection device.

[0033] See also Figure 1 and Figure 4A vertical electric push rod 103 is also fixedly mounted on the support plate 102, and a sealing plate 104 is fixedly connected to the output end of the vertical electric push rod 103. The sealing plate 104 is slidably sealed and connected to the end of the moisture detection air duct 202 away from the moisture detection sealing cylinder 201. The moisture detection control module is connected to the vertical electric push rod 103 by signal. The sealing plate 104 can seal the moisture detection air duct 202. When the device is in the standby state, air is prevented from entering the moisture detection air duct 202, so that the moisture detection breathable net 207 made of water-absorbing material can be kept dry. This can further improve the accuracy and reliability of the test results. During the test, the humidity detection control module will first control the vertical electric push rod 103 to pull the sealing plate 104 to separate the sealing plate 104 from the humidity detection air duct 202, so that the humidity detection air duct 202 is connected so as not to affect the progress of the test. After the test, the humidity detection control module controls the horizontal electric push rod 203 to push the piston plate 204 to reset, and then the humidity detection control module controls the vertical electric push rod 103 to push the sealing plate 104 to reset, so that the sealing plate 104 will re-seal the humidity detection air duct 202.

[0034] See also Figure 1 and Figure 4 A wind speed sensor 105 is also fixedly installed on the support plate 102. The humidity detection control module is connected to the wind speed sensor 105 signal. A wind speed threshold is reasonably set through the detection setting module. During detection, the humidity detection control module will first start the wind speed sensor 105, so that the wind speed sensor 105 detects the wind speed at this time, and the wind speed data detected by the wind speed sensor 105 will be transmitted to the humidity detection control module. If the real-time wind speed is greater than the wind speed threshold, the humidity detection control module will wait until the real-time wind speed drops to less than the wind speed threshold, and then control the extraction ratio humidity detection component for detection, thereby avoiding the wind speed from affecting the detection result, and further improving the accuracy and reliability of the detection result.

[0035] The second implementation method:

[0036] See also Figure 5-Figure 8, which is different from the first embodiment, an electric heater 209 is fixedly installed in the moisture detection sealing cylinder 201, and the electric heater 209 is located on the side of the piston plate 204 close to the moisture detection air duct 202. The moisture detection control module is connected to the electric heater 209 by signal. In this embodiment, after the detection is completed, the moisture detection control module turns off the pressure sensor 208, and first controls the vertical electric push rod 103 to push the sealing plate 104 to reset, so that the sealing plate 104 blocks and seals the moisture detection air duct 202, and then the moisture detection control module starts the electric heater 209 to heat, so as to dry the moisture on the moisture detection breathable net 207 made of water-absorbing material. After a certain period of time, The humidity detection control module will control the vertical electric push rod 103 to pull the sealing plate 104, so that the humidity detection air duct 202 is connected, and then the humidity detection control module will control the horizontal electric push rod 203 to push the piston plate 204 to reset, so that the hot air passes through the humidity detection breathable net 207, which can further dry the moisture on the humidity detection breathable net 207. Finally, the humidity detection control module will control the vertical electric push rod 103 to push the sealing plate 104 to reset again, so that the sealing plate 104 blocks and seals the humidity detection air duct 202. The above operations can restore the humidity detection breathable net 207 made of water-absorbing material to a dry state, which can be beneficial to subsequent detection.

[0037] See also Figure 6-Figure 8 A combined dust detection component is arranged in the moisture detection air duct 202 in one of the extraction ratio moisture detection components, and the combined dust detection component includes a dust detection sealing cylinder 401 fixedly installed in the moisture detection air duct 202, and a distance sensor 402 is fixedly installed on the inner wall of the dust detection sealing cylinder 401 away from the moisture detection air permeable net 207, and a sliding rod 403 is penetrated on the outer wall of the dust detection sealing cylinder 401 close to the moisture detection air permeable net 207, and the end of the sliding rod 403 close to the moisture detection air permeable net 207 is fixedly connected to a force-bearing circular plate 404, and the end of the sliding rod 403 away from the moisture detection air permeable net 207 is fixedly connected to the force-bearing circular plate 404 and the measuring card circular plate 405, and the sliding rod 403 and the dust detection sealing cylinder 401 are fixedly connected. The outer wall is slidably sealed and connected, the diameter of the force-bearing circular plate 404 is smaller than the diameter of the moisture detection breathable net 207, the measuring card circular plate 405 is located directly in front of the distance sensor 402, and the end of the measuring card circular plate 405 away from the distance sensor 402 is fixedly connected with a pair of elastic pull ropes 406, and the end of the elastic pull ropes 406 away from the distance sensor 402 is fixedly connected to the inner wall of the dust detection sealing cylinder 401, and the diameter of the measuring card circular plate 405 is larger than the diameter of the sliding rod 403. A dust detection and control module is also provided in the environmental detection intelligent controller 003. The detection setting module and the moisture detection control module are both connected to the dust detection and control module by signal, and the dust detection and control module is also connected to the distance sensor 402 and the remote alarm module by signal.

[0038] A distance threshold is reasonably set through the detection setting module. When the detection starts, the humidity detection control module will send a signal to the dust detection control module. After receiving the signal, the dust detection control module will start the distance sensor 402, so that the distance sensor 402 monitors the distance between it and the measuring card circular plate 405, and the distance data monitored by the measuring card circular plate 405 will be transmitted to the dust detection control module in real time, so that the dust detection control module analyzes the distance data monitored by the measuring card circular plate 405 according to the distance threshold, and determines whether the dust concentration in the air exceeds the normal value (that is, whether the dust concentration is greater than the level suitable for agricultural growth). During the detection process, when the humidity detection control module controls the horizontal electric push rod 203 to pull the piston plate 204 to extract air, the airflow acts on the force-bearing circular plate 404, which will push the force-bearing circular plate 404, causing the measuring card circular plate 405 to move in the direction close to the distance sensor 402. Dust will affect the force of the airflow, and the higher the dust concentration in the air, the smaller the force of the airflow, and the measuring card circular plate 405 The smaller the moving distance, the smaller the shortest distance between the measuring card circular plate 405 and the distance sensor 402. When the dust concentration exceeds the normal value, the distance between the measuring card circular plate 405 and the distance sensor 402 will always be greater than the distance threshold and cannot reach below the distance threshold. Therefore, the dust detection and control module can analyze the distance data monitored by the measuring card circular plate 405 according to the distance threshold, and determine whether the dust concentration in the air exceeds the normal value. When the judgment result is that the dust concentration exceeds the normal value, the dust detection and control module will control the remote alarm module to warn the relevant personnel. In addition, after the humidity detection control module controls the horizontal electric push rod 203 to pull the piston plate 204, it will send a signal to the dust detection and control module again, causing the dust detection and control module to turn off the distance sensor 402. Therefore, through the setting of the combined dust detection component, the detection device in the present application can detect whether the dust concentration in the air exceeds the normal value while detecting the air humidity, thereby greatly improving the practicality and functionality of the detection device.

[0039] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
