In one embodiment, the mobile living body detection module may include an infrared detection unit, and specifically, the infrared detection unit may be disposed in the device housing, and a detection portion of the infrared detection unit may be disposed on a transparent window or a through hole formed in the device housing, and when the mobile living body approaches a preset area, an infrared trigger signal may be generated by the infrared detection unit, and the infrared detection unit may transmit the infrared trigger signal to the control module. Specifically, the infrared detection unit may be, for example, a pyroelectric infrared detection unit, and it is understood that, in the case of a temperature change, the pyroelectric infrared detection unit may cause a surface polarization charge to be generated in a certain direction, that is, a potential to change, through a built-in spontaneous polarization crystal. When a moving living body appears in a relevant area, namely when infrared radiation emitted by the moving living body irradiates the pyroelectric material, the pyroelectric material can generate certain potential change correspondingly, and the living body movement can be judged by conditioning and amplifying a signal of the potential change. In this embodiment, the infrared trigger signal may be used to indicate that the current isolation boundary of the control module is close to the mobile living body, that is, when the mobile living body is close to the preset region, the infrared detection unit may detect infrared radiation emitted by the mobile living body, and in a scene of practical application, based on that the infrared detection unit can only sense the mobile living body in a certain region and a certain distance, a plurality of infrared detection units may be further set according to a practical environment, so that more regions may be detected by the infrared detection unit. In addition, the infrared detection unit may be triggered after a certain preset distance is set, for example, within three meters or within one meter, when the moving living body approaches the infrared detection unit within three meters or within one meter, the infrared detection unit may generate an infrared trigger signal and transmit the generated infrared trigger signal to the control module, so that the control module may control the sound warning module to perform a voice warning according to the infrared trigger signal.

Based on the fact that the moving living body breaks into the isolation boundary at the moment in the actual scene, the control module can control the sound warning module to emit a preset sound warning, wherein the preset sound warning is, for example, "you enter the radiographic inspection area and please leave immediately". Specifically, as shown in fig. 7, the early warning system may further include a reflective assembly 12, where the reflective assembly 12 is configured to reflect the laser emitted by the laser detection unit, and in an actual scene, the reflective assembly 12 may be specifically disposed on a side corresponding to the early warning apparatus 1.

The reflective member 12 can receive the laser light sent by the laser detection unit and reflect the laser light, so that the laser detection unit can detect whether a moving living body passes according to whether the reflected laser light changes, and in this embodiment, it can be understood that the reflective member 12, the laser light 121 emitted by the laser detection unit, and the early warning device 1 can form an isolation boundary. When a moving living body intrudes, the moving living body can shield laser emitted by the laser detection unit, namely the reflection component 12 cannot receive the laser within preset time, if the reflection component 12 cannot reflect the laser, the laser detection unit cannot receive the reflected laser, and at the moment, the laser detection unit can generate a laser trigger signal according to the change of the currently received laser and send the laser trigger signal to the control module.

the control module is used for controlling the sound warning module to send out preset sound warning according to the received laser trigger signal.
4. The warning system of claim 3, wherein the warning device comprises a visual warning module and an audible warning module;
when the control module receives the laser trigger signal and/or the laser trigger signal, the control module controls the visual alarm module and the sound alarm module to give out alarm reminding.
5. The warning system of claim 4, wherein the warning system comprises a light reflecting assembly;
the light reflecting component is arranged at one end opposite to the early warning device and used for reflecting the laser emitted by the laser detection unit so that the laser detection unit can detect whether the moving living body passes through according to the change of the reflected laser, and the light reflecting component, the laser and the early warning device form an isolation boundary.
6. The warning system of claim 5, wherein the warning system includes a warning band module disposed at a bottom end of the warning device; the warning belt module comprises a warning belt and a warning belt connecting end, and the warning belt connecting end is arranged at the bottom end of the reflecting component; the warning tape is connected with the warning tape connecting end and used for forming an isolation boundary.
7. The early warning system of claim 6, wherein the visual alert module comprises a warning light module disposed at a top end of the device housing, the warning light module configured for real-time alerting of an isolated boundary site.
8. The warning system of claim 7, wherein the warning device comprises a radiation dose detection module and a radiation intensity reminding module;
the radiation dose detection module is arranged in the device shell and used for detecting the radiation dose of an isolation boundary field and sending the radiation dose to the control module, so that the control module controls the radiation intensity reminding module to remind the radiation intensity according to the intensity of the radiation dose;
the radiation intensity reminding module is arranged in the device shell and used for responding to the control of the control module to send out radiation intensity reminding.
9. The warning system of any one of claims 4 to 8, further comprising a mounting device comprising a fixed base and/or a mounting rod;
the fixed base is movably arranged on the wall body, and the early warning device is movably arranged on the fixed base; and/or the early warning device is movably arranged on the mounting rod.
10. The warning system of claim 9, wherein the power module includes a power detection unit and a low power audible and visual alert unit;
the electric quantity detection unit is arranged in the device shell and used for detecting the electric quantity information of the power supply module and sending the electric quantity information to the control module, so that the control module controls the low-electric-quantity acousto-optic reminding unit to send out low-electric-quantity reminding according to the electric quantity information;
the low-power acousto-optic reminding unit is arranged in the device shell and used for responding to the control of the control module to send out low-power reminding.
