The measurement process and principle of the millimeter wave sensor 1 will not be described here.

[0022] When the millimeter wave sensor 1 detects that there are people within the safe distance of the construction vehicle, it triggers the warning module to send a warning signal, thereby reminding people and drivers near the vehicle to pay attention to avoid, thereby ensuring the safe driving of the construction vehicle at the construction site and safe construction at the construction site.

[0023] The power module 5 may adopt a rechargeable battery pack of the prior art to provide the millimeter wave sensor 1 and the warning module with the power required for operation. The specification of the power module 5 may be adaptively selected according to actual use requirements.

The number and adsorption position of the utility model can be adaptively adjusted according to actual needs, such as the rear of the vehicle, both sides of the vehicle body, and the front of the vehicle. The shell 3 can be made of polycarbonate (PC) material, which has a high hardness and can reduce fragmentation during collision and damage to internal electronic components.

[0025] The warning module includes a light module 2 and a sound module 6. The light module 2 is embedded in the top of the shell 3 so that the light module 2 is set facing the construction site; the sound module 6 is embedded in the shell 3, and a first hollow portion 10 is formed on the shell 3 at a position aligned with the sound module 6, so that the sound module 6 is set facing the outside of the shell 3 through the first hollow portion 10.

[0026] Preferably, the light module 2 can adopt an LED light to provide warning light to achieve the purpose of warning, especially at night, which can have a better warning effect.

[0027] Preferably, the sound module 6 can be a buzzer, a speaker, etc., which is used to provide a warning sound to achieve the purpose of warning, and can provide an effective warning effect for keeping a distance between people and vehicles in a noisy environment.

[0028] A second waterproof cloth 8 is provided at the first hollow portion 10 of the housing 3 , and the sound module 6 is located on the inner side of the second waterproof cloth 8 .

[0029] Preferably, the second waterproof cloth 8 can be made of a material such as adhesive tape, plastic cloth, etc. that has good waterproof and dustproof properties and is non-sound absorbing, which can prevent rain, dust, etc. from adversely affecting the normal use of the sound module 6.

[0030] The power module 5 is a rechargeable power supply, and a second hollow portion is formed on the housing 3 at a position aligned with the charging port 9 of the rechargeable power supply, so that the charging port 9 is arranged to face the outside of the housing 3 through the second hollow portion.

[0037] Please see attached Figure 1 , the working principle of the utility model is:

[0038] When the engineering vehicle is driving at the construction site, the housing 3 is adsorbed on the vehicle body through the magnetic chassis 11 and is located at a height of at least 1 m above the ground, so as to reduce the impact of the complex construction site environment on the detection of the millimeter wave sensor 1.

[0039] The millimeter wave sensor 1 accurately detects whether there are people around the construction vehicle based on millimeter waves. If a person is detected, an electrical signal is sent to the warning module to make the light module 2 always on or flash, and at the same time make the sound module 6 emit an alarm sound, thereby playing an effective alarm role through the combination of sound and light, reminding nearby personnel and construction vehicle drivers to avoid each other and avoid accidents.

[0040] The power module 5 is used to provide working power for the millimeter wave sensor 1, the light module 2 and the sound module 6. When the power module 5 is low on power, the housing 3 is removed from the engineering vehicle and charged through an external power source through the charging port 9.
