Description

technical field [0001] The invention relates to the fields of electronics, wireless communication and remote control equipment, in particular to an industrial wireless remote control device and a remote control method. Background technique [0002] In the field of industrial control, there are many devices that need frequent start-stop control, as well as related simple switch control, such as driving control, elevator control, etc. At present, the control methods adopted by most factories and enterprises mainly include: fixed switch control, through There are three control methods: long-distance control with wired cables, and wireless radio frequency control. [0003] The control of a fixed switch requires an operator to control it all the time or the operator needs to walk between the device and the switch for control. This kind of control is inefficient and wastes human resources; long-distance control with wired cables Remote control, this kind of control is more effici...

Problems solved by technology

[0003] The control of a fixed switch requires an operator to control it all the time or the operator needs to walk between the device and the switch for control. This kind of control is inefficient and wastes human resources; long-distance control with wired cables Remote control, this kind of control is more efficient than fixed switch control, the operator can hold the remote control within a certain range, walk around control, but this control method is limited by the distance of the cable, and in some factories, dragging the cable Cable control has certain potential safety hazards; the wireless radio frequency control method, also known as wireless remote control module, avoids the shortcomings of the first two control methods and has high remote control efficiency. However, most of the current wireless remote control modules are infrared remote control, Bluetooth remote control, and WIFI remote control. , these three remote control methods have short distances and are subject to certain restrictions. At present, there are wireless remote control modules in the ISM frequency band, but most of them focus on the development and application of remote control coding and decoding. For some remote control with relatively high safety factor equipment, there are potential safety hazards
