The device is controlled by TMS320F2812 microprocessor. It mainly includes signal acquisition circuit, keyboard
circuit, Chinese / English LCD display circuit, the calendar clock circuits, alarm circuits, relay output circuit,
communications interface circuits, DI / DO circuit, power circuit and CPU circuit and so on. In addition, the device
integrates a sensor transmission circuit, so it can directly connect with temperature pressure sensors to achieve
high-precision measurement and monitoring. According to needs of users, it can work in different modes without the
additional controller respectively. The equipment can communicate with each other by CAN bus or RS485. It mainly can
realize the control and analysis of equipment status, failure predication and diagnosis, information management, etc.
