Abstract

The invention relates to a remote wake-up system and method based on 125 KHz wireless wake-up signals. A command and control end instruction starting module is used for sending a wake-up instruction to a 125 KHz low-frequency wireless wake-up module; according to the wake-up instruction, the 125 KHz low-frequency wireless wake-up module generates 125 KHz low-frequency wireless wake-up signals; a mixing modulation module performs carrier modulation of the 125 KHz low-frequency wireless wake-up signals; a radio-frequency sending module sends the modulated wireless wake-up signals to a remote unmanned working unit; a radio-frequency receiving module receives the wireless wake-up signals; a low-pass filtering module performs low-pass filtering of the received wireless wake-up signals; a power meter screening module performs power screening of filtered low-frequency signals, so that the 125 KHz low-frequency wireless wake-up signals are obtained; and a working module of the remote unmanned working unit wakes up the remote unmanned working unit according to the wake-up signals. By means of the remote wake-up system and method based on the 125 KHz wireless wake-up signals disclosed by the invention, the signal transmission distance is far; and furthermore, the problem that the power consumption of unattended equipment is too high can be solved.

Description

technical field [0001] The invention relates to the technical field of wireless signal transmission, in particular to a remote wake-up system and method based on a 125KHz wireless wake-up signal. Background technique [0002] At present, remote unmanned work units work in sparsely populated areas, even in areas where humans cannot reach, and the work of remote unmanned work units can only rely on limited power sources (such as batteries) for power supply. However, in practical applications, it is usually required that the remote unmanned work unit can work for a long time in a harsh and harsh environment. It is not practical to replace the power supply of the remote unmanned work unit frequently at the work site, which poses a threat to the remote unmanned work unit. The application of it brings a very sharp contradiction. It can be seen that the power supply energy has great constraints on the application of remote unmanned work units. Therefore, the present invention pro...
