With the development and progress of industrial technology, the temperature range of factory substations is required strictly, and most of the temperature measuring devices widely used in the market at present are single-point measurements, with the disadvantages of slow transmission speed and imprecision, etc., it is disadvantageous for the controller of the substation equipment to make a decision in time according to its temperature change. This subject is based on single-chip microcomputer as the core of the control components, the acquisition temperature through the acquisition channel multiplexing technology, to achieve multi-point temperature monitoring and recording. A temperature measurement and control system is composed of a / D conversion photosensitive triode, a temperature sensor and a light intensity acquisition, detection and display. The temperature sensor is controlled by a single-chip microcomputer to collect the temperature, and the temperature is fed back to the single-chip microcomputer to make corresponding analysis and processing, it has powerful data processing function, intuitive display, friendly interface and high cost performance, and can be widely used in industrial and agricultural control, mechatronics engineering, smart home and many other fields.
