Problems solved by technology

The biggest flaw of this type of system is that it cannot support multiple monitoring groups (that is, the monitor and the monitored) to work simultaneously in the same area
If two monitoring groups use the same frequency to work in the same area at the same time, when a monitored person is lost, because the two hosts will receive the signal of another monitored person, the result will be that neither monitor will receive the signal. Call the police
Although different monitoring groups can work simultaneously on different frequencies in the same area, due to the limited frequency available and no mechanism to assign different operating frequencies, the end result is that it is impossible to guarantee that each monitoring group has a only frequency, a major drawback that makes the widespread use of such systems impossible

Embodiment 1

[0027] In this example, there are host A and slave B. The host includes a microprocessor MCU, and the microprocessor is connected to the WPAN / WLAN transceiver chip. Its input terminal is connected with a set of input control keys, and its output terminal is connected with LCD display components and light-emitting diodes. 1. Loudspeaker, the microprocessor is provided with an output end that can output audio signals of different frequencies according to the strength of the input signal, and this end is connected with the loudspeaker; the slave machine includes a microprocessor MCU, and the microprocessor is connected with the WPAN / WLAN transceiver chip, its The input end is connected with a group of input control keys, and the output end is connected with a light-emitting diode LED and a speaker.

[0028] In this example, the MCU of the master and slave can use Amtel’s AT82ZL3201 microprocessor, and the wireless transceiver module can be implemented by different devices for diff...

Embodiment 2

[0054] Image 6 This example describes a monitoring group consisting of two hosts A1, A2 and three slaves B1, B2, B3, which includes one-to-one, one-to-many, many-to-one, and many-to-many master-slave collocation. The connection in the figure represents the monitoring relationship between the master and the slave. The collocation of this monitoring relationship is established by figure 1 shown. If any of the slaves in the monitoring relationship (such as A1-B1) is out of the monitoring range, the corresponding master (A1) will prompt the monitor and enter the positioning mode for this slave (B1), while still monitoring other slaves model.

[0055] That is to say, since each master and slave has a unique MAC, whether it is one-to-many, many-to-one, or many-to-many, multiple independent matching monitoring channels can be established in the same monitoring group. Moreover, they do not interfere with each other, and different monitoring groups will not interfere with each oth...

Abstract

The present invention relates to a child or pet missing warning and location method and its system. It includes main machine controlled by monitor and slave machine attached to the monitored body, the main machine and slave machine can make wireless data communication and data exchange between them so as to monitor and locate the slave machine. Said communication can be implemented by using radio data communication mode which can utilize WPAN or WLAN wireless communication protocol to make data exchange. Said invention also provides its concrete application method.

Description

technical field [0001] The invention belongs to a method and device for positioning and monitoring movable bodies, in particular to a method and system device for positioning and monitoring children or pets moving in a certain area. Background technique [0002] In order to effectively prevent and retrieve lost children or pets in the shortest time, existing inventions generally use analog wireless communication methods to monitor children or pets. The basic working principle is as follows: the system generally includes a host and a slave. , the master and the slave each have wireless transceivers and work at the same frequency, and their working range is generally tens of meters to one or two hundred meters. When the master sends a signal, if the distance from the slave to the master exceeds the working range, it will cause the master to fail to receive the signal from the slave within a specified period of time. At this time, the master will send a warning to inform the mo...
