[0036] The upper end of the detection rod 1 is fixed to the surface of the soil to be monitored. A plurality of support rods are welded on the outer periphery of the upper end pipe mouth of the detection rod 1, so as to support the upper end of the detection rod 1 on the ground and vertically insert the lower end into the soil to be monitored.

The sensor probe 11 can pass through the corresponding detection hole 8 on the detection rod 1 under the thrust of the booster 12 and extend into the soil; the sensor probe 11 and the booster 12 are both electrically connected to the control device 4.

[0037] The hole digging component 16 includes a motor, a rotating blade 164 and a hole digging head 165. The hole digging head 165 is fixedly connected to the fixed rod 163. The outside of the fixed rod 163 is connected to the rotating blade 164. A protection box 162 is provided on the upper part of the fixed rod 163. A motor is provided in the protection box 162. The motor is connected to the fixed rod 163. The motor drives the fixed rod 163 and the rotating blade 164 to rotate to dig holes. A connecting groove 161 is provided on the upper part of the protection box 162. The connecting groove 161 can be connected to the hollow disc 3 and the detection rod 1 and connected to the control device 4 through the connection with the hollow disc 3. The start of the hole digging component 16 is controlled by the control device 4. After the hole digging is completed, the hole digging component can be tested, or the connecting groove 161 can be separated from the hollow disc 3, and the connecting groove 161 can be connected to the bottom of the detection rod 1, and then taken out together with the detection rod 1 after the detection is completed.

[0038] The control device 4 is provided with a main control module, a storage module, a communication module, a power circuit, a charging management module, a signal processing module and a lithium battery. The storage module, the power circuit, the communication module and the signal processing module are electrically connected to the main control module respectively. A wireless signal transmitting antenna is installed on the control device 4. The wireless signal transmitting antenna and the storage module are electrically connected to the communication module. The charging module is electrically connected to the lithium battery and the lithium battery protection module through the charging management module. The charging management module is electrically connected to the power circuit. The soil moisture sensor is electrically connected to the signal processing module through a wire passing through the inner wall of the hollow rod 14.

[0039] The main control module includes a sensor control module and a relay control module, the sensor control module is electrically connected to the soil moisture sensor, the communication module is a wireless communication module or a Bluetooth module, and the communication module is connected to the main control module; the storage module includes an EEPROM storage chip and a FLASH storage chip, the EEPROM storage chip and the FLASH storage chip are electrically connected to the main control module, and the power supply module includes a sensor power supply and a relay power supply, and the sensor power supply and the relay power supply are electrically connected to the power supply circuit.

[0040] Through the main control module, enter the configuration mode of the device to configure parameters, such as setting the networking port, the operation interval, and the configuration of the mounted sensor. After the basic operating parameters are set, exit the configuration mode and enter the normal operation mode. If the current data collection cycle is the data collection cycle, the device will first collect data and store it in FLASH. If the current upload cycle is the upload cycle, the device will connect to the network and receive commands or configuration parameters issued by the platform after connecting to the cloud platform. When the platform has no commands and configuration parameters, the device will extract the data that has not been uploaded from FLASH and upload it. If the device cannot connect to the cloud platform, the device will store the collected data, then sleep, and wait for the next cycle to wake up.

[0041] The storage module includes EEPROM storage chip and FLASH storage chip. The parameters required for operation are stored in the EEPROM storage chip. The data collected during operation is stored in the FLASH storage chip, and the operation parameters are backed up. The dual storage area can reduce the probability of data loss. Tens of thousands of data can be stored in FLASH. If the device cannot connect to the Internet, the data will be overwritten cyclically. Once the network can be connected, the device will package the inventory data in the order of the collection time within a communication cycle. As long as the cycle time has not expired, the data will continue to be uploaded. When the cycle time is up, it will enter sleep and wait for the next wake-up.

[0042] The storage module has a dual-memory cross-recovery function. The equipment operation data will be stored in two storage areas and will be locked for read-only. The device will read the parameters during operation. If the parameters are found to be incorrect, data will be extracted from the two storage areas for cross-comparison, and then the correct data will be used to overwrite the incorrect data. If the data in both storage areas are lost, the device returns to initialization and notifies the cloud platform to re-issue the configuration parameters to restore the operation of the device. If the equipment encounters an unexpected power outage during operation, or abnormal conditions such as lightning strikes cause the loss of operating parameters, data loss can be effectively avoided. Through the intelligent control function, the device will read the sensor data and perform data cleaning after waking up, and transmit the data to the data storage system for storage. The data storage system conducts data difference analysis based on deep learning of historical data. When the monitored soil moisture data exceeds a certain threshold of historical data, the device will immediately issue a warning to remind the user to pay attention to the abnormal data.

[0043] The buttons 5 include a forced restart button, a forced initialization button, a custom function button, an on button and an off button, wherein the on button is used to control the booster 12 to insert the sensor probe 11 into the soil; the off button is used to control the booster 12 to retract the sensor probe 11 from the soil under the joint action of the booster 12 and the spring 6, and the button 5 is electrically connected to the control device 4.

[0044] By long pressing the forced initialization button, the device can be forced to initialize; a restart command can be issued through the cloud platform to force the device to restart. The device will also check various parameters during operation. If there are any parameter errors, it will enter recovery mode and restart the device. You can also force the device to restart by pressing the restart button.

[0045] The electronic screen 15 is used to obtain and display soil moisture data obtained by the sensor probes 11 at different depths and to display information such as abnormal conditions of the monitoring data and alarm records.

[0046] The working principle is as follows: select a suitable detection location, dig a hole through the digging component 16, and then put the monitoring equipment in for monitoring. The position of the hollow rod 14 and the sensor probe 11 can be placed according to needs to perform all-round detection of moisture. The charging module charges the lithium battery through the charging management module and the lithium battery protection module. The lithium battery supplies power to each hardware module through the power circuit. The signal processing module processes the soil information collected by the soil moisture sensor and sends it to the main control module and stores it in the storage module. The main control module exchanges information with the external management equipment through the communication module, which is convenient for centralized processing of soil information, easy to maintain, economical and reliable.

[0047] Therefore, the present invention adopts the above-mentioned soil moisture monitoring device with little disturbance and quick installation and disassembly, which is arranged on the top of the detection rod through a hollow disc and fixed in position by a buckle; it has the advantage of monitoring soil moisture at different depths, and solves the problem that the existing technology cannot monitor deep soil moisture in situ with little disturbance, and at the same time reduces the adsorption force between the outer wall of the drill bit and the soil, which is easy to carry and can be quickly installed and disassembled, thereby improving work efficiency. Through the intelligent control function, the device will read the sensor data and perform data cleaning after waking up, and transmit the data to the data storage system for storage; the data storage system calls historical data to conduct data difference analysis based on deep learning. When the monitored soil moisture data exceeds a certain threshold of historical data, the device will immediately issue a warning to remind the user to pay attention to the abnormal situation of the data; through the IP switching function, the device will store 2 IPs, and when the main IP cannot be connected for multiple times, it will automatically switch to the backup IP, and the main and backup IPs can also be switched manually, which is convenient for the replacement and deployment of the cloud platform.

[0048] The battery of the present invention converts the voltage into different voltages required by the control part through the power supply part to power each hardware module. The signal processing module processes the soil moisture information collected by the soil moisture collector probe and sends it to the controller and stores it in the storage module. The storage module stores the parameters required for operation and the data collected during operation, and backs up the operation parameters. The dual storage areas can reduce the probability of data loss. The controller is connected to the server through the communication module to receive the server's commands and parameters, and uploads the collected data at the same time, which is convenient for centralized processing of soil information, easy to maintain, economical and reliable.

[0049] Through the restart function of the present invention, the cloud platform can issue a restart command to force the device to restart. The device will also check various parameters during operation. If there is a parameter error, it will enter the recovery mode and restart the device. The local machine also has a restart button to force the device to restart; the device has a forced initialization button to initialize the device; through the dual-memory cross-self-recovery function, the device can be prevented from encountering abnormal conditions such as unexpected power outages during operation, which may cause the loss of operating parameters.

[0050] The present invention can effectively avoid data loss through two memories. The equipment operation data will be stored in two storage areas and will be locked for read-only. The equipment will read parameters during operation. If it is found that the parameters are incorrect, data will be extracted from the two storage areas for cross-comparison, and then the correct data will overwrite the erroneous data. If the data in both storage areas are lost, the equipment returns to initialization and re-sends the configuration parameters through the cloud platform to restore the operation of the equipment.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
