This self-control unit is the accumulation and crystallization of our company's experience in the design, installation and commissioning of automatic monitoring systems for heating industry for several years. It is based on the principle of economy, high efficiency, energy saving, and special purpose. It is easy to install, easy to use, and simple to maintain. Based on the reference, analysis, and summary of other types of heat transfer station control systems and control devices, they have been developed. In terms of hardware selection, this automatic control unit uses military-grade and industrial-grade components, which lays a solid hardware foundation for improving the mean time between failures (MBTF) of the automatic control unit. In terms of software design, this automatic control unit has adopted a large number of mature design concepts of Chinese configuration software. A heat exchange station requires only one set of the device, an external sensor (temperature, pressure), and an actuator (electrically controlled valve) to achieve all control requirements for an unattended heat exchange station. Its input and output channel names, physical quantity units (units of measurement, such as 0-5V or 4-20mA, etc.) required for input and output of each channel, upper limit value, lower limit value, communication rate (communication baud rate) All of them can be defined, set and modified by the user according to their own needs and habits in the Chinese environment through the LCD screen. It greatly facilitates installation, commissioning, and routine maintenance and maintenance. It has laid a solid software foundation for long-term, stable, and reliable operation of the system.
The automatic control unit has been considered in the design of remote set, operation and monitoring, management functions, therefore, the automatic control unit is compatible in hardware with a GPRS data transmission module, an embedded touch screen. The communication protocol adopts the international standard MODBUS-RTU protocol and has good software compatibility. It can easily realize the entire operation status of the heat exchange station, remote data acquisition, parameter setting, alarm and disposal, and remote operation of related equipment. Control, management, etc. Unique features in function selection, channel setting, channel customization, various parameter settings, fault self-diagnosis, equipment protection and alarm, etc., is a truly simple, practical, reliable and intelligent with energy-saving operation mode and effect. Monitoring unit.
This product is a dedicated control unit for unattended heat transfer station automation and energy saving operation. In order to improve the heat supply company's real-time monitoring and management of many heat exchange stations and equipment operations, save manpower and material resources, and improve economic efficiency, the control unit is designed with two RS485 communication interfaces, in addition to local operation, monitoring and management. , You can also achieve remote (using GPRS modules, etc.) operation, monitoring and management.
