Actuating mechanism based on wireless communication technology

Abstract

The invention discloses an actuating mechanism based on a wireless communication technology, which comprises a control unit connected with a valve position feedback unit, a driving module, a wirelesscommunication module and an actuating mechanism body; the wireless communication module comprises a communication processor, a radio frequency chip, a peripheral circuit interface and a wireless transceiving antenna; and the control unit comprises a sampling circuit, a display, an infrared remote control receiver, a fault detection device and an alarm output device which are connected to a microprocessor. The problems that in the prior art, packet loss is high, power consumption is high, and the service life of a battery is short are solved, through arrangement of the wireless communication module composed of the communication processor, the radio frequency chip, the peripheral circuit interface and the wireless receiving and transmitting antenna, installation of a low-power-consumption long-distance Internet of Things module on an executing mechanism is achieved, and finally low-power-consumption long-distance communication is achieved.

Description

technical field [0001] The invention relates to an actuator, in particular to an actuator based on wireless communication technology. Background technique [0002] Electric actuator is one of the three main instruments in the field of industrial automation, widely used in electric power, metallurgy, petrochemical, textile, food, medicine and other industries. With the continuous development of electronic technology, the performance requirements of actuators in industrial process control are increasing day by day. At present, most of the actuators on the market adopt the wired method, especially the intelligent actuator products have mature technology. On the basis of retaining the traditional 4-20mA industrial standard electrical signal, they also have fieldbuses such as HART, ProfiBus, and FF. communication method. However, the wired method is not suitable for use in harsh on-site environments. Wireless actuators can make up for this gap. They can be used in places where ...

AI Technical Summary

Problems solved by technology

[0004] Most of the existing industrial wireless instruments and meters use the method of forming a local area network or a wide area network to transmit information wirelessly, but long-distance and low power consumption can only be selected from one of the two, and it has the disadvantages of frequent packet loss, high power consumption, and short battery life.
