The soil moisture rapid measuring instrument is widely used in agricultural research and guiding planting. It is very convenient, but recently customers have reported it. Because it has not been carried out according to the operation guide, some faults have occurred. The information is from our manufacturers. In fact, these are some basic faults. Through some solutions, you can easily get it. Here are some common faults that customers have reflected.
The common faults of soil moisture rapid measuring instrument mainly include data missing, jumping, abnormal trend, etc. Because soil moisture recorder is mainly composed of collector, sensor, GPRS communication module and solar power supply module, when the instrument fails, it can be Check each component item by item to find out why. The duty officer should check the operation status of the instrument through the observation system software of the soil moisture rapid tester every day to check whether the data can be uploaded on time. If the data is missing or abnormally jumped, it should be checked to the instrument site in time to check whether the appearance of the instrument is present. Damage, each component and the connection line are normal, and the collector, sensor and other parts can be further inspected after confirming that the instrument is complete.
Collector fault identification of soil moisture rapid tester:
(1) Power supply inspection. Check whether the power indicator is always on. If it is not lit, check whether the power terminal of the collector board is loosely connected. If the wiring is secure, unplug the cable and plug in the power terminal. If it cannot be started, use a multimeter to measure whether the battery voltage is normal. The normal range is 12V~15V. If it is not normal, the battery needs to be replaced. If the voltage is normal, the motherboard is faulty and the motherboard needs to be replaced.
(2) Acquisition program operation check. If the running indicator is blinking normally, if the indicator is not blinking, the motherboard is faulty and the motherboard needs to be replaced.
(3) Serial communication check. Use the debugging software to communicate with the collector through the RS232 interface, first read the clock operation (Note: Since the GPRS collector will detect the link status with the GPRS server at any time, it sometimes affects the RS232 communication, but once the RS232 communication is detected, it is at least within 3 minutes. The link status with the GPRS server is no longer detected, and RS232 communication will not be affected during this period. If the continuous read clock is normal and the date is correct, the serial port communication of the collector is normal.
(4) GPRS communication check. Check whether the indicator light is always on. If it is not lit, check whether the SIM card is installed correctly, whether it is in arrears, check the GPRS signal status in the area, check whether the interface of the GPRS antenna is off, if it falls off, reinstall it; pass RS232 The interface reads the IP address and port of the server. If it is incorrect, reset it. If the above checks are normal and you still cannot log in to the server, you can determine that the GPRS module is faulty and you need to replace the acquisition board.
Sensor fault identification of soil moisture rapid tester:
(1) Check the terminal block. Check if the jumper cap is off, and press the cable pins connected to each layer of the sensor and the motherboard to ensure reliable connection between the connected devices.
(2) Sensor appearance inspection. Turn off the power switch first, open the protective cover, and plug the sensor to see if there is any sign of water. If the sensor copper ring has water drops or rust, you can judge the sensor casing water, causing sensor damage, unable to measure data normally, or even If there is no data upload, it should be waterproofed and replaced in time; check whether the connection between the sensor circuit board and the two copper ring plates is off. If it falls off, it can be soldered with a soldering iron; the sensor card slot is loose or damaged, and the RS485 interface is damaged. Problems such as damage to the sensor processing board and loose connection wires may cause the sensor and the collector to communicate incorrectly, and the debugging software will not be able to communicate with the sensor for debugging.
(3) Software debugging of soil moisture recorder. A problem with the sensor will directly lead to singular values ​​or abnormal behavior. Use the automatic soil moisture observation system software to browse the soil moisture value. If the water value of a certain level is abnormally high or too low, read the sensor frequency value of the layer, the normal range should be 30-80Mhz, if the frequency value exceeds This range indicates that the sensor of this layer may be in contact with the problem or has been damaged. If the sensor is still unable to be solved, the sensor needs to be replaced.
Analysis of other common problems in soil moisture rapid tester:
(1) The soil moisture data sometimes has regular intermittent conditions. This may be caused by incorrect setting of the power controller's control mode. The correct power supply mode should be “6â€. If there is data interruption, check the mode setting. is it right or not.
(2) The failure of the power supply system will result in the loss of data. The normal indication state of the power controller, the green light on the left indicates that the solar panel is powered normally, the middle green light indicates that the battery voltage is normal, and the orange on the right indicates that the power supply of the circuit board is normal. If the middle indicator light indicates yellow, the battery is under voltage. If it is red, it indicates that the battery is under heavy pressure and cannot work. If the right indicator is not lit, it indicates that the power switch is not turned on or the battery undervoltage controller is automatically turned off. According to the indication state of the power controller, the cause of the fault can be determined, and the power supply system fault can be solved by troubleshooting the power supply line and replacing the battery.
(3) The soil moisture recorder using wired transmission sometimes has the situation that the collected data is normal and the uploaded message data cannot be generated. This is because the instrument runs for a long time and the number of generated packets is too large, which exceeds the folder of the Windows system. The maximum number of files is limited, and the backup message can be compressed to solve this problem.
