Automatic remote control system capable of resisting robbing and preventing it from being lost

Abstract

The invented automatic remote system for guarding against jijacker, theft and loss includes the host and the extension. The host consists of the send receive module, the all-directional displacement tranducer, the CPU, the sound alarm etc. The extension is composed of the send receive module, CPU the command control and sound alarm etc circuit. The host uses the all-directional displacement transducer to obtain the displacement change signal of the protected article, starting up the bi-directional data communication to the extension. With the information of the host being received, the extension changes the state from the discontinuous reception to the discontinuous transmission. The extension obtain each signal of the state change of the host, sending different hint sound to reflect the state of the host so as to reduce the power consumption and increase the channel utilization rate.

Description

technical field [0001] The invention relates to an automatic remote control system for anti-robbery, anti-theft and anti-loss, which belongs to the field of electronic information and security, and is a replacement product of the existing anti-theft and relic alarms and wireless automatic remote control. Background technique [0002] At present, the existing relic alarms all rely on the master machine to continuously receive the signal emitted by the slave machine to realize the detection and alarm of the relic. This way of working will cause only one set of equipment to work on one wireless channel in the same area, and the channel cannot be reused. The handset is often in the transmitting state and the transmission rate is low, resulting in high power consumption. It can only alarm and prompt, but cannot control two-way remote control, control the action of anti-robbery and anti-theft equipment, and cannot prevent the behavior of wireless code detection. Another example ...

AI Technical Summary

Problems solved by technology

This way of working will cause only one set of equipment to work on one wireless channel in the same area, and the channel cannot be reused.

The handset is always in the transmitting state and the transmission rate is low, resulting in high power consumption

It can only alarm, not two-way remote control, can not control the action of anti-robbery and anti-theft equipment, and can not prevent the behavior of wireless code detection

Another example is that the existing car alarms rely on passive alarm sounds to inform the theft, often false alarms disturb the people, and cannot actively prevent theft and refuse theft
