Embodiment 1
[0065] see figure 1 It is an accurate multi-point real-time temperature measurement system for permanent magnet synchronous motors. It includes a host computer 1 and a lower computer 2. The temperature signal is collected in real time through a temperature sensor. After the resistance signal is converted into a voltage signal by the conditioning circuit 203, the A / The D conversion module 205 processes it into a digital signal that can be recognized by the digital system, and the lower computer processor DSP206 completes tasks such as signal sampling, calibration circuit control, and data transmission. The upper computer 1 mainly performs parameter setting, filtering and signal processing, and performs real-time display and data storage of the obtained temperature signal. The upper computer 1 and the lower computer 2 communicate in real time through the communication bus.
[0066] When the motor is not started, the measurement system is connected, and the DSP206 controls the ...
Embodiment 2
[0076] Embodiment 2: The measurement system given in this embodiment is not much different from Embodiment 1. On the basis of Embodiment 1, a keyboard and a screen module 208 are added to the lower computer 2 to undertake the work of system parameter setting and temperature signal real-time display respectively. . In this system, the lower computer processor DSP206 mainly completes tasks such as calibration circuit control, filtering, signal processing, and temperature display. The upper computer 1 can complete tasks such as parameter setting and temperature data storage through the communication port as required, and the temperature data can also be stored in the memory card of the lower computer 2 or the hard disk of the upper computer 1 .
