Background technique

In the process of scientific research or actual production, temperature is an important information of equipment operation status. It is often necessary to detect the temperature status during equipment operation. Sometimes in order to avoid local temperature being too high or too low, it is necessary to monitor The temperature of multiple points is detected, such as the overall operating temperature of the motor, the operating temperature of the bearing, or the air outlet temperature of the vent, so that corresponding control measures can be taken. Therefore, multi-point temperature remote monitoring has important application value in scientific research and actual production.

At home and abroad, there have been extensive researches on multi-point temperature detection of equipment, and there are many methods of temperature measurement proposed. Among them, the typical temperature measurement system has an analog temperature sensor detection method, but because the output of the analog temperature sensor is Analog signals must undergo A/D conversion to interface with microprocessors such as single-chip microcomputers. The work of this system is very complicated and the cost is high. In addition, the signals of analog sensors are susceptible to interference during transmission, which reduces the accuracy and accuracy of system detection. Stability, so it is not easy to realize multi-point detection of a certain device.

To sum up, the traditional analog temperature sensor detection method has the disadvantages of poor reliability, low accuracy and precision. The temperature measurement and control system composed of these analog temperature sensors has two main disadvantages:

First, a large number of connections are required to send the signal of the on-site sensor to the acquisition card, and the wiring construction is troublesome and the cost is high;

Second, what is transmitted on the line is an analog signal, which is susceptible to interference and loss.

Now in most temperature measurement systems, digital temperature sensors are used, and they use a single-bus operation mode, that is, only one data line is used to transmit temperature information and control instructions, and at the same time, it is very convenient to connect multiple temperature sensors to the bus. The sensor constitutes the multi-point working mode of the temperature sensor. Under the control of the controller, it can detect the temperature of multiple points in a circuit, and can set high and low temperature over-limit alarms and other functions. The structure is simple and reliable, and the temperature detection system is suitable for detecting the global temperature parameters of the equipment.

Based on the above analysis, the present invention proposes a modular structure with rich functions, simple design, and the temperature sensor adopts a matrix distribution structure, and the temperature sensing device has the function of stretching and deformation, which can control various shapes and sizes of working equipment. A temperature detection system of matrix temperature detection. The application of this system can effectively improve work efficiency and meet the needs of scientific research and actual production. It has certain practical and popularization value.
