Radio-frequency remote-control wireless intelligent electric actuator

Abstract

A radio-frequency remote-control wireless intelligent electric actuator consists of an electric actuator and a wireless handheld manipulator in two-way wireless communication with the electric actuator. The electric actuator comprises a control circuit, a driving circuit, an input-output signal interface circuit, a radio-frequency wireless transceiving circuit and a power circuit, wherein the driving circuit is connected with the control circuit, and the power circuit is respectively connected with the control circuit and the driving circuit. An output of the driving circuit is connected with an actuating mechanism, and a signal feedback end of the actuating mechanism is connected with the control circuit. The wireless handheld manipulator comprises a display and control circuit, a radio-frequency wireless transceiving circuit and a battery, wherein the radio-frequency wireless transceiving circuit is connected with the display and control circuit, and the battery is connected with the display and control circuit and the radio-frequency wireless transceiving circuit. The radio-frequency remote-control wireless intelligent electric actuator is widely applied to the industrial fields of petroleum, chemical engineering, metallurgy, cement, light industry; water treatment and the like, uniqueness of controlled equipment, reliability in two-way transmission of wireless signals and long-term stability of equipment are guaranteed; and mounting, debugging, operating and daily polling of the electric actuator are more convenient and simpler.

Description

technical field [0001] The invention relates to an electric actuator. In particular, it relates to a radio frequency wireless remote control intelligent electric actuator. Background technique [0002] Electric actuators are widely used in production and life, such as petroleum, chemical industry, metallurgy, cement, light industry, water treatment, building automation, fire protection and other fields. Usually, the electric actuator is controlled by a distributed system or a programmable controller to adjust the opening of the valve. However, during installation and commissioning or when the valve needs to be manually adjusted on site for some reason, the button or button installed on the electric actuator body must be operated. If the installation position of the knob is not conducive to manual operation, it will bring great difficulties to on-site installation and commissioning. After the equipment is put into operation, it is not convenient to check the operating status...

Problems solved by technology

Usually, the electric actuator is controlled by a distributed system or a programmable controller to adjust the opening of the valve. However, during installation and commissioning or when the valve needs to be manually adjusted on site for some reason, the button or button installed on the electric actuator body must be operated. Knobs, if the installation position is not conducive to manual operation, it will bring great difficulties to on-site installation and commissioning. After the equipment is put into operation, it is not convenient to check the operating status of the equipment or manually operate it.

In response to this situation, there is an infrared remote control currently on the market to solve this problem, but the infrared remote control device has the problems of strong directivity and unreliable two-way communication, and does not support address code operation. It is intended to control an electric actuator, but it will cause multiple electric actuators to move; there is also a radio frequency wireless remote control, but it can only control the electric actuator in one direction, the status information of the electric actuator cannot be displayed on the remote control, and it does not support the address Code operation, so it will also cause the problem of multiple actuators; the above two devices only partially solve the remote control problem; the existing drawbacks make the wireless remote control operation of electric actuators unable to be popularized on a large scale
