Embodiment Construction

[0027] Below with reference to shown in accompanying drawing, the present invention is further described by specific embodiment:

[0028] like figure 1 and 2 As shown, a BDS-based computer remote control and information collection method, the remote control process of the method is: the computer remote control terminal converts information into BDS short message format Morse code in the Beidou terminal equipment in the form of short messages Encrypted and sent to the Beidou satellite, the signal is amplified and processed by the satellite and then forwarded to the remote control circuit. After the front-end antenna of the remote control circuit receives the satellite signal, it is processed by a low noise amplifier and a surface acoustic filter and then transmitted to the RF chip for further filtering and amplification processing. The intermediate frequency signal is obtained through image suppression and frequency mixing processing. The intermediate frequency signal is furth...

Abstract

The invention discloses a computer remote control and information collecting method based on a BDS. A computer remote control end converts information into a BDS short message format Morse code on Beidouo terminal equipment in a short message mode and encrypts and sends the BDS short message format Morse code to a Beidou satellite, a signal is amplified through the satellite and then transmitted to a remote control circuit, an antenna at the front end of the remote control circuit receives the satellite signal, the satellite signal is processed through a low-noise amplifier and a sound surface filter and then is transmitted into a radio frequency chip to be further filtered and amplified, mirror rejection and mixing are conducted on the satellite signal, and therefore an intermediate frequency signal is obtained. The intermediate frequency signal is further amplified and filtered in the radio frequency chip and transmitted to a baseband chip, the baseband chip analyzes a short message according to a Beidou protocol, the short message is sent to a rear end information processing part MCU, the MCU converts the short message into a corresponding order according to message content, the high and low level at an on-off key pin or a hard disk data destruction pin is controlled, and the control over on-off of a computer and the destruction of hard disk data is achieved.

Description

technical field [0001] The invention relates to the field of computer remote management, in particular to a BDS-based computer remote control and information collection method, which is applicable to the field of high-safety computer use. Background technique [0002] In the fields of military application, wildlife monitoring, ocean exploration, plateau mining, operation control of mountainous hydropower stations, etc. or in remote areas, there is a high demand for remote management of computers. The traditional method of managing remote operation computers with the help of mobile operator networks Due to the shortcomings and limitations of poor confidentiality and no signal coverage in remote areas, it cannot meet the existing application requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is: the present invention is proposed based on the demand for computer remote management in the field of remote unmanned operati...
