In order to avoid electromagnetic interference in the external environment and simultaneously avoid the influence of external environmental factors (such as temperature, humidity and/or dust, etc.), the at least one pressure sensor 10 preferably employs a friction generator and/or a piezoelectric generator, and/or a pressure-sensitive cable based on the friction generator and/or the piezoelectric generator, and/or a piezoelectric and triboelectric hybrid generator, which are sequentially disposed outside, so as to ensure the normal operation of the at least one pressure sensor 10.

In order to be able to monitor the pressure acting on the pressure sensor-based warning device of the present embodiment in a comprehensive and accurate manner, a plurality of pressure sensors are preferably provided. More preferably, the at least one pressure sensor 10 is a plurality of pressure sensors, each of which monitors the pressure applied to a different location of the user's body.

The number of the preprocessing modules 20 may be one or multiple, and since the first ends of the preprocessing modules 20 are connected to the output ends of the at least one pressure sensor 10 in a one-to-one correspondence, the number is determined by the number of the output ends of the at least one pressure sensor 10. For example: if the number of the at least one pressure sensor 10 is one, i.e. has one set of outputs, the number of the preprocessing module 20 is one; if the number of the at least one pressure sensor 10 is three, and the three pressure sensors are individually connected, and each pressure sensor has one group of output ends, that is, three groups of output ends, the number of the preprocessing modules 20 is three; if the number of the at least one pressure sensor 10 is three and the at least one pressure sensor has two groups of output ends after being connected in series and/or in parallel, the number of the preprocessing modules 20 is two; by analogy, the description is omitted here.

In addition, when the at least one pressure sensor 10 is a plurality of pressure sensors, and each pressure sensor monitors the pressure applied to different positions of the body of the user, the central control module 30 is not only used for processing the electrical signals output by the plurality of pressure sensors, but also used for judging which pressure sensor the electrical signals are generated from, and further judging whether to output a positioning start signal and an alarm reminding signal. In order for the central control module 30 to be able to determine which pressure sensor the electrical signal originates from, the first end of the central control module 30 should also comprise the same number of ports as the number of outputs of the at least one pressure sensor 10 and the number of pre-processing modules 20, for example: if the number of at least one pressure sensor 10 is one, i.e. has a set of outputs, the number of pre-processing modules 20 and the number of ports comprised by the first end of the central control module 30 are both one; if the number of the at least one pressure sensor 10 is three and the three pressure sensors are individually connected, each pressure sensor having one set of outputs, i.e. three sets of outputs, the number of the preprocessing modules 20 and the number of the ports included in the first end of the central control module 30 are both three; if the number of the at least one pressure sensor 10 is three and the at least one pressure sensor has two sets of output terminals after being connected in series and/or in parallel, the number of the preprocessing modules 20 and the number of the ports included in the first end of the central control module 30 are both two; by analogy, the description is omitted here.

Optionally, as shown in fig. 3, the preprocessing module 20 further includes: the device comprises a rectifying module 21, an amplifying module 22, a filtering module 23 and an analog-to-digital conversion module 24; the rectifying module 21 is connected to at least one pressure sensor 10, and is configured to rectify an electrical signal output by the at least one pressure sensor 10; the amplifying module 22 is connected with the rectifying module 21 and is used for amplifying the electric signal output by the rectifying module 21; the filtering module 23 is connected to the amplifying module 22 and is configured to filter interference noise in the electrical signal output by the amplifying module 22; the analog-to-digital conversion module 24 is connected to the filtering module 23, and is configured to convert the analog electrical signal output by the filtering module 23 into a digital electrical signal, and output the digital electrical signal to the central control module 30.

Specifically, the input end of the rectifying module 21 (i.e. the first end of the preprocessing module 20) is connected to the output end of the at least one pressure sensor 10, and is configured to rectify the electrical signal output by the output end of the at least one pressure sensor 10; the input end of the amplifying module 22 is connected to the output end of the rectifying module 21, and is configured to amplify the electrical signal output by the output end of the rectifying module 21; the input end of the filtering module 23 is connected to the output end of the amplifying module 22, and is configured to filter interference noise in the electrical signal output by the output end of the amplifying module 22; the analog-to-digital conversion module 24 has an input end connected to the output end of the filtering module 23, and an output end (i.e., the second end of the preprocessing module 20) connected to the first end of the central control module 30, and is configured to convert the analog electrical signal output by the output end of the filtering module 23 into a digital electrical signal and output the digital electrical signal to the first end of the central control module 30.

It should be noted that the above modules (i.e. the rectifying module 21, the amplifying module 22, the filtering module 23 and the analog-to-digital conversion module 24) are optional modules, and those skilled in the art can select them according to actual needs, and are not limited herein. For example: if the rectification processing is not needed, the rectification module 21 can be omitted, and the output end of at least one pressure sensor 10 is directly connected with the input end of the amplification module 22; by analogy, the description is omitted here.

The central control module 30 may be a CPU, a single chip, etc., and those skilled in the art can select the central control module according to actual needs, which is not limited herein.

Specifically, generally, when the bullet is hit, the pressure acting on the at least one pressure sensor 10 is relatively large, and there is a positive correlation between the pressure acting on the at least one pressure sensor and the magnitude of the voltage, that is, as the force is increased, the voltage generated by the at least one pressure sensor 10 is also gradually increased. Therefore, in order to effectively reduce the false alarm rate and make the determination more accurate, a preset voltage threshold is set in the central control module 30. When the magnitude of the voltage signal output by at least one pressure sensor 10 is greater than or equal to the preset threshold, the central control module 30 outputs a positioning start signal to the positioning module 40, the positioning module 40 generates positioning information according to the positioning start signal and outputs the positioning information to the central control module 30, and the central control module 30 generates an alarm reminding signal including the positioning information according to the positioning information and sends the alarm reminding signal to the terminal device through the wireless transceiver module 50. On the contrary, when the magnitude of the voltage signal output by the at least one pressure sensor 10 is smaller than the preset threshold, the electrical signal is determined to be an interference signal, the central control module 30 does not generate a corresponding positioning start signal, and the determination is continued.

For example, the predetermined voltage threshold in the central control module 30 is 50 volts. When the central control module 30 monitors that the voltage signal output by the at least one pressure sensor 10 is greater than or equal to 50 volts, it is determined that the user is hit by a bullet, the central control module 30 outputs a positioning start signal to the positioning module 40, the positioning module 40 generates positioning information according to the positioning start signal and outputs the positioning information to the central control module 30, and the central control module 30 generates an alarm reminding signal including the positioning information according to the positioning information and sends the alarm reminding signal to the terminal device through the wireless transceiver module 50. On the contrary, when the central control module 30 monitors that the magnitude of the voltage signal output by the at least one pressure sensor 10 is less than 50 volts, the voltage signal is determined to be an interference signal, the central control module 30 does not generate a corresponding positioning start signal, and the determination is continued.

It should be noted that the preset voltage threshold in the central control module 30 can be set arbitrarily, and is not limited herein. In addition, the preset voltage threshold in the central control module 30 may be not only a point value but also a range, and is not limited herein. When the range is reached, the central control module 30 monitors whether the magnitude of the electrical signal output by the at least one pressure sensor 10 is within the corresponding range, so as to determine whether to output an alarm reminding signal and a positioning starting signal.

Alternatively, the positioning module 40 may adopt a prior art satellite positioning system module, such as a global positioning module, a beidou satellite navigation module, a galileo satellite navigation module, etc., and those skilled in the art can select the module according to actual needs, which is not limited herein.

Optionally, the wireless transceiver module 50 is a wireless transceiver module in the prior art, and a person skilled in the art can select the wireless transceiver module according to actual needs, which is not limited herein.

The wireless transceiver module 50 may also receive a positioning request signal sent by the terminal device, and output the positioning request signal to the central control module 30; after receiving the positioning request signal, the central control module 30 generates a positioning start signal and outputs the positioning start signal to the positioning module 40; after receiving the positioning start signal, the positioning module 40 generates positioning information and transmits the positioning information to the terminal device through the central control module 30 and the wireless transceiver module 50 in sequence.

In addition, the wireless transceiver module 50 may also receive a positioning start signal sent by the terminal device, and output the positioning start signal to the central control module 30; after receiving the positioning start signal, the central control module 30 outputs the positioning start signal to the positioning module 40; after receiving the positioning start signal, the positioning module 40 generates positioning information and transmits the positioning information to the terminal device through the central control module 30 and the wireless transceiver module 50 in sequence.

Optionally, the switch module 60 employs a key switch and/or a touch switch in the prior art, and those skilled in the art can select the switch according to actual needs, which is not limited herein.

It should be understood that the switch module 60 is connected at a first end to an output of the power module 70 and at a second end to a power input of the central control module 30, and that the other modules (i.e., the preprocessing module 20, the positioning module 40, the wireless transceiver module 50, the physiological monitor module 80, and the alarm module 90) receive power directly or indirectly from the power input of the central control module 30; however, the second terminal of the switch module 60 may also be connected to the power input terminals of other modules, and is used to determine whether other modules are operating or not by controlling whether the power module 70 supplies power.

The power module 70 is a power module in the prior art, for example, a rechargeable power module, and those skilled in the art can select the power module according to actual needs, which is not limited herein.
