[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Reference Figure 1-3A remote support device for a ground meteorological observation station includes a ground meteorological observation station remote support device body electrically connected to a ground meteorological observation sensor, the ground meteorological observation station remote support device body including a remote monitoring platform, a data transmission unit, a monitoring module, a power monitoring management unit, a load priority control switch, and a lightning detection control unit, the data transmission unit is connected to the remote monitoring platform, the monitoring module, and the power monitoring management unit, the remote monitoring platform is connected to the power monitoring management unit, the load priority control switch, and the lightning detection control unit, and the power monitoring management unit, the monitoring module, the load priority control switch, and the lightning detection control unit are all connected to the ground meteorological observation sensor;

[0029] The remote monitoring platform includes a PLC controller;

[0030] The power monitoring and management unit includes solar panels, wind power generators, diesel generators, main power supply terminals, main batteries, inverters, priority switches, backup batteries, rectifiers, status monitoring modules, and sound and light alarms. The solar panels and wind power generators are electrically connected to the main batteries, and the rectifiers are electrically connected to the diesel generators and backup batteries. The rectifiers are used to convert alternating current (AC) into direct current (DC). The diesel generators generate AC power, and when it needs to be stored in the backup batteries, the rectifiers are required to convert the AC power into DC power for storage in the backup batteries.

[0031] The inverter is electrically connected to the backup battery, the main battery, and the ground-based meteorological observation sensor. The inverter is used to convert the DC power of the main battery and the backup battery into AC power to power the ground-based meteorological observation sensor. The inverter can adjust the conversion efficiency and power output according to the different energy inputs.

[0032] The mains power supply terminal is electrically connected to the ground meteorological observation sensor, and the mains power supply terminal can directly power the ground meteorological observation sensor. The status monitoring module is electrically connected to the main battery and the backup battery. The status monitoring module, the priority switch and the sound and light alarm are all connected to the PLC controller. The load priority control switch is used to control the opening and closing of the ground meteorological observation sensor. When the voltage of the main battery, the backup battery and the mains power supply terminal is insufficient, the PLC controller controls the load priority control switch to automatically adjust the load, shut down the operation of non-critical equipment, give priority to ensuring the power supply of core functions, and avoid equipment shutdown due to power exhaustion;

[0033] The priority switch is electrically connected to the mains power supply terminal, the discharge terminals of the main battery and the backup battery. The priority switch is used to control the opening and closing of the main battery, the backup battery and the mains power supply terminal. The main battery is the primary power supply battery.

[0034] The status monitoring module includes a voltage sensor, a current sensor, and a temperature sensor. The voltage sensor is used to monitor the output voltage levels of the main battery, backup battery, and AC power supply in real time. If the main battery and backup battery are detected to be low in voltage, it means that the battery power is insufficient.

[0035] The current sensor is used to monitor the current of the main battery and backup battery during the charging and discharging process in real time. The current is used to determine the charging and discharging status of the battery. If abnormal current is detected, it indicates that the main battery and backup battery are aging.

[0036] The temperature sensor is used to monitor the temperature of the main battery, backup battery and AC power supply equipment in real time. If the temperature is too high, the battery and power supply equipment will be damaged.

[0037] The data monitored by the voltage sensor, current sensor and temperature sensor are transmitted to the remote monitoring platform through the data transmission unit, wherein the data transmission unit adopts a digital channel to transmit data signals. When abnormal current and high temperature are detected, the PLC controller will control the sound and light alarm to send out sound and light alarms to remind personnel to perform maintenance operations. The PLC controller judges the voltage, current and temperature parameters according to the thresholds pre-set by the staff. Different batteries and mains power supply systems have different voltage, current and temperature parameters, and their thresholds are set according to specific circumstances. When the voltage sensor detects that the main battery power supply voltage is insufficient, the PLC controller will cut off the power supply of the main battery through the priority switching switch and turn on the backup battery for power supply. When it is detected that the power supply voltage of both the main battery and the backup battery is insufficient, the mains power supply end will be turned on for power supply. The power supply priority is main battery > backup battery > mains power supply end.

[0038] For example, the normal voltage range is usually 23V-28V, so the voltage threshold is set to 23V-28V. When the voltage is lower than 23V, it is considered undervoltage. The rated current is 10A. When the overload current is 20%-50% higher than the rated current, it is considered abnormal. The normal operating temperature of the power supply device and battery is between -5℃ and 45℃. When the temperature is higher than 45℃, it is judged as overtemperature.

[0039] The lightning detection control unit includes a lightning sensor and a first control switch. The ground meteorological observation sensor includes a ground meteorological observation sensor at station A and a ground meteorological observation sensor at station B. The lightning sensor is used to monitor lightning conditions. When lightning is detected, the ground meteorological observation sensor at station A or the ground meteorological observation sensor at station B is controlled to be turned off through the first control switch. When the ground meteorological observation sensor at station A is working, the ground meteorological observation sensor at station B is controlled to be turned off. Conversely, the ground meteorological observation sensor at station A is controlled to be turned off. This avoids the situation where the ground meteorological observation sensor at station A and the ground meteorological observation sensor at station B are damaged by lightning at the same time when lightning occurs, thereby reducing losses caused by lightning strikes.

[0040] The utility model adopts a hybrid power supply mode, which can effectively avoid the problem of insufficient power supply caused by severe weather, reduce dependence on renewable energy, and can monitor the power supply situation in real time during the power supply process, and switch to a suitable power supply in time when the voltage is insufficient, so as to achieve stable power supply for ground meteorological observation sensors. In addition, when the power supply voltage at the mains power supply end is still insufficient, the load can be automatically adjusted to give priority to the power supply of the core function ground meteorological observation sensors, avoid the situation where the ground meteorological observation station equipment is shut down due to power exhaustion, further improve the power supply stability, and can automatically control some of the sensors to shut down when lightning occurs, avoid the situation where the sensors are damaged by lightning at the same time, and reduce lightning strike losses.

[0041] Working principle: When in use, the operating status of the ground meteorological observation sensor is monitored through the monitoring module, and the monitored data is transmitted to the remote monitoring platform through the data transmission unit for monitoring. The specific monitoring principle is the existing technology of the remote support device of the ground meteorological observation station, which will not be elaborated here.

[0042] During the use of ground meteorological observation sensors, solar panels and wind generators use solar energy and wind energy to generate electricity respectively. The direct current generated is stored in the main battery, and the inverter converts the direct current into alternating current to provide normal power for the ground meteorological observation sensors. At the same time, the voltage sensor, current sensor and temperature sensor in the status monitoring module monitor the output voltage, current and temperature of the main battery respectively, and transmit the monitored data to the remote monitoring platform through the data transmission unit. The PLC controller judges the data according to the threshold set by the staff. When abnormal current and high temperature are detected, the PLC controller will control the sound and light alarm to send out sound and light alarms to remind personnel to perform maintenance operations. When it is detected that the power supply voltage of the main battery is insufficient, the PLC controller cuts off the power supply of the main battery through the priority switching switch, and starts the backup battery for power supply. At the same time, the diesel generator is turned on and the diesel generator is powered on. The machine generates AC power through diesel generator and converts it into DC power through rectifier and stores it in the backup battery. The inverter converts the DC power of the backup battery into AC power to power the ground meteorological observation sensor. During the use of the backup battery, the status monitoring module still monitors the status of the backup battery. When it is monitored that the voltage of the backup battery is still insufficient, the PLC controller cuts off the backup battery through the priority switching switch and turns on the mains power supply end for power supply. By monitoring the power supply status in real time during the power supply process and switching to the appropriate power supply in time when the voltage is insufficient, stable power supply for the ground meteorological observation sensor can be achieved. In addition to relying on renewable energy power supply, the hybrid power supply mode can also be powered by diesel generators and mains power supply, which can effectively avoid the problem of insufficient power supply caused by bad weather, and can achieve the effect of complementary power supply under different weather conditions, reducing dependence on renewable energy.

[0043] When it is detected that the power supply voltage at the mains power supply end is still insufficient, the PLC controller will automatically adjust the load through the load priority control switch, shut down the operation of non-critical ground meteorological observation sensor equipment, give priority to ensuring the power supply of core function ground meteorological observation sensors, avoid the situation where the ground meteorological observation station equipment is shut down due to power exhaustion, and further improve the stability of the ground meteorological observation station equipment operation;

[0044] In addition, during use, the lightning situation is monitored by the lightning sensor, and the information is transmitted to the PLC controller. When lightning is detected, the PLC controller controls the ground meteorological observation sensor of station A or the ground meteorological observation sensor of station B to be turned off through the first control switch. When the ground meteorological observation sensor of station A is working, the ground meteorological observation sensor of station B is controlled to be turned off, and vice versa, the ground meteorological observation sensor of station A is controlled to be turned off, so as to avoid the situation where the ground meteorological observation sensor of station A and the ground meteorological observation sensor of station B are damaged by lightning at the same time when lightning occurs, thereby reducing the loss caused by lightning strike.

[0045] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
