Problems solved by technology

However, while providing convenience, it also brings new problems: these key switches all have a common feature - they are touch or push type key switches, and their common operation mode requires the user to touch and operate with fingers.
Due to its technical limitations, it cannot be widely used in other places

Embodiment approach

[0020] The non-touch intelligent key switch is applied to the corridor switch of the parking lot. The implementation method is to set a non-touch intelligent key switch at the starting point of the corridor and the end point after turning back, which are equivalent to the midpoint of the average human body. Lighting lamps are installed on the ceiling at the turning in the middle (if it is a single-run corridor, the lighting lamps are installed in the middle of the corridor). The received signal of the switch at both ends is transmitted to the signal central processor at the lighting lamp, and the processed signal controls the opening and lighting time of the lighting lamp. The operation method is that pedestrians follow the operation guide on the corridor gate or switch, and use the back of their hand to wave the non-touch intelligent key switch (the front of which is illuminated by LED lights) within 1-200mm, and the signal of turning back is transmitted to the light at the li...

Abstract

The invention discloses a control method of a non-contact intelligent key switch and a system thereof. In the method, a signal transmitted by a virtual key transmitting circuit is reflected by a finger shading plate and then is received by a receiving circuit; and a signal entering a signal central processor is determined and then is subjected to intelligent processing operation such as prolonging, accumulation, gradual accumulation, regressiveness, clearing, resetting and the like so as to replace a signal generated by the traditional key switch and be input into the traditional actuator to finish corresponding work. The system comprises a virtual key partition board, a transmitting circuit, the receiving circuit, a signal central processor, an acoustic-optic display module, an actuator and the like. With the system, a common contact type key switch is changed into the non-contact intelligent key switch; and the system can be widely applied to various public facilities, avoid the pollution and disease spread caused by the contact type key switch, and provide a safe, sanitary and energy-saving environment for the public. The non-contact technology is applied to the medical community for operating various instruments and equipment, is greatly convenient for the work of medical staff, improves the efficiency, and reduces the crossed infection in hospitals.

Description

technical field [0001] The invention relates to a novel key switch control method and system thereof, in particular to a non-touch intelligent key switch control method and system thereof. It is suitable for the use and acquisition of equipment required by non-contact technology, shared facilities and information in public places, such as medical instruments, equipment, elevators, digital locks for dormitory doors, bank teller machines, POS machines, vending machines, ticket machines, corridor lighting Lights, self-service crosswalk lights, push-button walkie-talkies, telephones, entertainment electronics, computer input devices, etc. Background technique [0002] Since the invention of electricity by human beings, various switches have been widely used to control various electrical appliances. Especially with the development of modern society, in many public places, people share switches to control the use and acquisition of various public facilities and information. It h...
