Embodiment 1

[0044] The post-disaster search and rescue life detection method provided by Embodiment 1 of the present invention is specifically as follows figure 2 shown, including the following steps:

[0045] Step 10, the life detection device monitors the wireless environment, and judges whether there is a wireless signal of the public mobile communication network.

[0046] The life detection device provided by the embodiment of the present invention is suitable for such as figure 1 The basic working principle of the life detection system shown is that the life detection device simulates the operation mode of the base station of the public mobile communication network, sends a control signal on the forward link control channel of the base station of the public mobile communication network, and induces the mobile phone receiving the control signal Initiate registration access to register mobile phone information.

[0047] Since the basic operating principle of the life detection devic...

Embodiment 2

[0062] In the solution provided by Embodiment 2 of the present invention, the life detection device first monitors the wireless network environment of the area to be detected, and if there is no public mobile communication network signal in the area, the life detection device sends forward link signals (pilot signal, synchronization Signals and system messages, etc.) are used to induce the mobile phone to initiate registration and access, and then obtain the mobile phone location and user information. If there is a public mobile communication network signal in this area, the life detection device enters a compatible state, decodes the forward link signal of the public mobile communication network base station, and realizes synchronization with the public mobile communication network base station, and sends a "registration request control" in the paging channel. "Information" controls the mobile phone on the surface of the ruins to initiate registration again. The reason why th...

Embodiment 3

[0066] Such as image 3 As shown, the life detection device provided by Embodiment 3 of the present invention includes a wireless monitoring unit 100, a control signal unit 200, a forwarding unit 300 and a registration access unit 400, specifically as follows:

[0067] The wireless monitoring unit 100 is configured to monitor the wireless environment and determine whether there is a wireless signal of the public mobile communication network.

[0068] The control signal unit 200 is configured to generate and send a control signal.

[0069] Here, the control signal unit 200 is configured to generate and send a control signal that induces the mobile phone to initiate registration and access. Generally, this control signal is a control signal sent by the life detection device on the forward link control channel, such as pilot signal, synchronization signal and system message. After receiving these messages, the mobile phone will initiate a location update process. Thereby active...

Abstract

The invention discloses a life detection method for post-disaster research and rescue, which belongs to the technical field of post-disaster research and rescue life detection. The method includes that a life detection device monitors wireless environment and judges whether public mobile communication network signals exist or not. If the signals exist, the life detection device transfers communication signals between a public communication network base station and a mobile phone. If the signals do not exist, the life detection device transmits control signals, induces the mobile phone receiving the control signals to conduct register access, receives signals of the register access and registers information of the mobile phone. The life detection device is further provided. The life detection method can finish a life detection process by monitoring the wireless environment through the life detection device no matter the public mobile communication network signals exist or not, guarantees smooth development of detection work, effectively resolves the problem of effects on disaster area mobile communication caused by the fact that a life detection network can not be compatible with the public mobile communication network.

Description

technical field [0001] The invention relates to the technical field of post-disaster search and rescue life detection technology, in particular to a post-disaster search and rescue life detection method and a life detection device. Background technique [0002] Natural disasters have the characteristics of instantaneous occurrence, severe damage, difficulty in monitoring and forecasting, and far-reaching social impact. For example, destructive earthquakes, landslides and other disasters have caused huge harm and losses to national economic construction and people's life and property safety. Numerous cases of natural disasters at home and abroad prove that the technical level of post-disaster emergency rescue is extremely important for reducing disaster losses. [0003] At present, our country is still very weak in disaster emergency rescue technology, mainly relying on manpower, search and rescue dogs and life detection devices for life detection to find survivors. The dete...
