Problems solved by technology

[0002] The rescue device is equipped for the firefighters who enter the dangerous scene, and is used to ensure the safety of the firefighters; at present, in the emergency rescue scene in a large area, the rescue workers are equipped with a rescue device to communicate wirelessly with the walkie-talkie in the monitoring command center. In order to protect the safety of rescuers, the traditional way of calling for help is single-line transmission. If a single firefighter has an accident, the emergency call will continue until it is connected to the walkie-talkie. Call for help; in this way, if multiple rescue devices continue to call for help at the same time, they are connected to the walkie-talkie repeatedly or for a long time, which will lead to wireless network access congestion, signal interference, and the voice cannot be heard clearly on the walkie-talkie. Other rescue devices are difficult to access In an emergency situation, it is easy to cause the command center to not be informed of the call for help information of the rescue workers in time, delaying the best time for rescue, and posing a threat to the personal safety of the rescue workers

Embodiment 1

[0041] Such as figure 1 Shown, a kind of wireless voice alarm caller, including

[0042] Motion sensing module: used to collect the motion status signal of the person wearing the rescue device;

[0043] Voice warning module: used to store solidified language and send out wireless voice alarms. The voice warning module can be one channel or multiple channels; and

[0044] A processor and a storage medium, the processor receives the motion state signal, a program is stored in the storage medium, and when the program is run by the processor, the following steps are performed:

[0045] If it is judged that the wearer of the rescue device is in an abnormal motion state after receiving the motion state signal, after a preset waiting period, the voice warning module is controlled to send voice alarm signals to the monitoring receiver at intervals.

[0046] Among them, "abnormal motion state" refers to the abnormal rescue motion state such as small movement and static state of the p...

Embodiment 2

[0059] The application occasions of the present invention are large-area fire rescue and rescue, remote rescue and rescue at sea, forest rescue and rescue sites, etc. In this rescue environment, it is necessary to put in multiple rescue devices (generally, each rescuer wears one), so multiple rescue devices To form a system, the rescue devices in the system are on the same channel; it is also possible to work with multiple channels at the same time, so that multiple systems do not affect each other on the same site. Thus if figure 2 As shown, the present invention also provides a kind of wireless voice alarm calling system, comprising:

[0060] A plurality of rescue devices, and the plurality of rescue devices are wirelessly connected to the monitoring receiving end; the rescue devices include:

[0061] Motion perception module: used to collect the motion status signal of the rescue device;

[0062] Voice warning module: used for language storage and issuing voice warning; ...

Embodiment 3

[0070] Such as image 3 , 4 As shown, the present invention also provides a method for calling for help with a wireless voice alarm calling device, including:

[0071] S1. Collect the motion state of the wearer through the motion sensing module, and send the motion state signal to the processor of the rescue device;

[0072] S2. The processor judges the motion status signal, and if it is judged that the person is in an abnormal motion state, the sound and light alarm module is automatically triggered to perform a sound and light pre-alarm;

[0073] S3. After the pre-alarm, if the processor judges that the person is still in an abnormal motion state, it will automatically trigger a strong alarm; the strong alarm includes the sound and light alarm module for sound and flash frequency higher than the pre-alarm sound and light alarm, and the voice warning module The voice warning signal is sent to the monitoring receiver at intervals. And further, multiple rescue devices in the...

Abstract

The invention provides a wireless speech alarm distress device which comprises a motion sensing module, a speech alert module, a processor and a storage medium. The processor receives a motion state signal. A program is stored in the storage medium. The program executed by the processor comprises the step that after the motion state signal is received, if the fact that the distress device is in a non-normal motion state, the speech alert module is controlled to send a speech alarm signal to a monitoring receiving end at intervals after a preset waiting time period. According to the invention, in the automatic distress state of the distress device, the speech alarm signals of a number of distress devices in the same system basically do not completely overlap; and during the process of wireless transmission with the monitoring receiving end, the problem that the monitoring receiving end cannot receive speech due to simultaneous continuous access of a number of distress devices at the same time is solved. The invention further discloses a wireless speech alarm distress system and a distress method of the wireless speech alarm distress device to improve the distress reliability of the distress device.
