A radio frequency automatic remote control device and remote control method based on satellite positioning

Abstract

The invention relates to a radio-frequency automatic remote control device based on satellite positioning. The radio-frequency automatic remote control device comprises a control terminal and a controlled terminal, wherein the control terminal comprises a control end power supply module, a control module, and a satellite positioning module and a first radio-frequency module which are connected with the control module, as well as a triggering module capable of triggering the control terminal to work; and the controlled terminal comprises a controlled end power supply module, a controlled device and a second radio-frequency module connected with the controlled device. Correspondingly, the invention further relates to a remote control method of the radio-frequency automatic remote control device based on the satellite positioning, so that working and closing of the satellite positioning module can be automatically controlled according to a distance between the control terminal and the controlled terminal, working and closing of the satellite positioning module can be automatically controlled, influences of the radio-frequency modules on physical health of a user can be effectively controlled, the service life of each module of the device is ensured, and the device and the method have great market prospects.

Description

technical field [0001] The invention relates to a radio frequency automatic remote control device and a remote control method based on satellite positioning. Background technique [0002] Radio frequency identification technology (RFID) is a technology that identifies specific targets and reads and writes relevant data through radio signals. RFID can be divided into three categories: passive RFID, active RFID, and semi-active RFID; working frequencies are: low frequency 125 -134kHz, the recognition distance is less than 0.5m; high frequency 13.56MHz, the recognition distance is less than 1m; UHF 902-928MHz, the recognition distance is 4-8m; microwave is 2.54GHz, the recognition distance can reach 100m; among them, the passive RFID sensing distance Too short (less than 1m), high-frequency active RFID or semi-active RFID is expensive. Radio frequency identification technology is often used for short-distance wireless control, such as access control card swiping, wireless cont...

[0002] Radio frequency identification technology (RFID) is a technology that identifies specific targets and reads and writes relevant data through radio signals. RFID can be divided into three categories: passive RFID, active RFID, and semi-active RFID; working frequencies are: low frequency 125 -134kHz, the recognition distance is less than 0.5m; high frequency 13.56MHz, the recognition distance is less than 1m; UHF 902-928MHz, the recognition distance is 4-8m; microwave is 2.54GHz, the recognition distance can reach 100m; among them, the passive RFID sensing distance Too short (less than 1m), high-frequency active RFID or semi-active RFID is expensive

Radio frequency identification technology is often used for short-distance wireless control, such as access control card swiping, wireless control of garage parking spaces, etc., but for these existing applications, it is necessary to keep the RFID radio frequency module in working condition at all times, and detect the control terminal and the controlled terminal in real time. The distance between terminals, when the distance between each other reaches a controllable distance, complete the transceiver work of the RFID radio frequency module in time, so that the RFID radio frequency module that is always working will have an impact on the human body, because RFID radio frequency identification technology is usually used In terms of access control cards, garage parking spaces, etc., the distance between the human body in the RFID radio frequency module is very small, and the transmitting device continuously emits radio waves, which may affect the health of users due to the radiation of radio waves
