The disadvantages and deficiencies of these methods are: First, manual measurement is very dangerous, because the equipment and places to be tested are high-voltage, high-altitude, and difficult to access, which can easily cause harm to the measurement personnel
Secondly, although wired measurement avoids harm to the measuring personnel, because the method of wired measurement is to transmit measurement data through lines, the tedious and messy equipment lines make the installation quite cumbersome, the flexibility of measurement is greatly reduced, and it is difficult to change the lines once they are laid. , and the cost is relatively high

Embodiment Construction
[0021] As shown in the figure, the wireless temperature measurement system includes a wireless temperature measurement terminal 1, a wireless temperature measurement management machine 2 and an on-site computer 4. The wireless temperature measurement terminal 1 converts the measured temperature parameters into wireless signals and transmits them to the wireless temperature measurement management machine. 2. The wireless temperature measurement management machine 2 transmits the temperature parameters to the on-site computer 4 through the Ethernet 3 .
[0022] The wireless temperature measurement terminal 1 is composed of a power supply unit a, a resistance value calculation unit b, a data processing unit c, an address control unit d, and a data transmission unit e. The power supply unit a provides a 3.6V power supply for the temperature measurement terminal, and the resistance value The calculation unit b calculates the resistance value of the thermistor and converts the calcul...
