[0005] The temperature monitoring device is a very important part of the passive wireless temperature monitoring system. The software upgrade of the existing temperature monitoring device can only be done manually at the site of the high-voltage switchgear, and the temperature monitoring device is taken out from the secondary room of the high-voltage switchgear. To restore the original state after the program, a temperature monitoring device is installed in a high-voltage switchgear. Generally, there are more than 30 high-voltage switchgears in a substation. It will take a lot of time and manpower to complete the software upgrade of all temperature monitoring devices. Potential safety hazards are likely to occur during installation and power-off

Embodiment Construction
[0021] In order to make the present invention easier to understand, it will now be described in detail in conjunction with the accompanying drawings.
[0022] figure 1 Among them, the ARM built-in Flash of the temperature monitoring device is divided into four parts: bootloader program area 101 , application program area 102 , backup application program area 103 and liquid crystal font area 104 .
[0023] figure 2 The workflow of the software online upgrade of the temperature monitoring device is shown:
[0024] In step 2) 201, the software system of the temperature monitoring device is started and the bootloader program is executed. If an upgrade command is received within the 5s time window, go to step 3) 202, otherwise go to step 4) 203;
[0025] Step 3) In 202, the file is received through the Xmodem file transfer protocol. If an upgrade application program instruction is received, write it into the Flash application program area, set the application program area flag...

The invention is applicable to the field of on-line temperature monitoring of electric high-voltage switch cabinets, and provides an online software upgrading method of a temperature monitoring device. The software upgrade of the existing temperature monitoring device can only be done manually at the site of the high-voltage switchgear, and the temperature monitoring device is taken out from the secondary room of the high-voltage switchgear, disassembled and written into the program and then restored to its original state. This operation is extremely inconvenient and consumes a lot of manpower Material resources, and it is easy to cause safety hazards in the process of continuous disassembly and power-off and power-on. The invention can upgrade the software of the temperature monitoring device serially connected on the bus at one end of the RS485 bus in the monitoring room. The method is simple to operate, saves time and labor costs, and has high reliability and stability.
Description
technical field [0001] The invention relates to the field of on-line temperature monitoring of electric high-voltage switch cabinets. Background technique [0002] Modern society relies more and more on electricity, especially in areas with high electricity density, such as factories, commercial areas, and large-scale infrastructure. Without electricity, people's lives will fall into chaos. Therefore, modern power systems have higher and higher requirements for power quality, and correspondingly more and more requirements for electrical equipment. At the same time, the reliability of high-voltage switchgear is also required put forward higher requirements. With the development of the power grid and the continuous improvement of equipment, 10kV and 35kV high-voltage switchgears have been used in large quantities, and the problem of overheating inside the switchgear has become a common problem in the process of using the switchgear. Excessive heating of the switchgear will ca...
