Digital quantity wireless valve controller

Abstract

The invention discloses a digital quantity wireless valve controller which comprises a wireless valve upper end controller and at least one wireless valve lower end controller. The wireless valve upper end controller is composed of a system power supply, an MCU, a signal detection system and a relay system, wherein the MCU, the signal detection system and the relay system are in electric bidirectional connection with the system power supply. Each wireless valve lower end controller is composed of a system power supply, an MCU, a relay and a signal detector, wherein the MCU, the relay and the signal detector are in electric bidirectional connection with the system power supply. A PLC is connected with the wireless valve upper end controller. A valve is connected with the wireless valve lower end controller. The wireless valve upper end controller is in communication connection with the wireless valve lower end controller through a wireless signal receiving and transmitting unit. According to the digital quantity wireless valve controller, through wireless monitoring and controlling modes, remote control and state monitoring on a series of valves are achieved, thus, no line needs to be laid between the valve controllers, cost input is reduced, and relatively stable operation of the valve is guaranteed.

Description

technical field [0001] The invention relates to the field of valve remote control, in particular to an analog wireless valve controller. Background technique [0002] Wireless control is a major event in the development of control technology at present. In industrial processing and production, wireless control has become indispensable in industrial processing with small input cost and stable control performance. [0003] In the prior art, many valves in the current valve control application are remotely monitored by the PLC through the bus to the valves in different positions. When establishing such a control system, it is necessary to lay a large number of cables, which not only increases the amount of construction Moreover, the cost is increased. In the later maintenance, the cables that have been laid outdoors for a long time cause serious line aging, which makes maintenance more difficult and affects the stability of the equipment.
