[0029] The security speaker 8 can play the corresponding voice information according to the instruction from the central control module, and the sound and light alarm 7 can be turned on or off according to the instruction from the central control module.

[0030] The camera module captures the video stream through its lens and converts it into a digital image. The camera module transmits the image information to the central control module. The central control module uses the target detection algorithm in the built-in deep learning technology to identify the target object in the image. If it is detected that there are people who are not wearing safety helmets and reflective clothing in the image, the security speaker 8 and the sound and light alarm 7 are sent to remind the on-site construction personnel to wear safety helmets and reflective clothing in a standardized manner. At the same time, the violation information of the on-site construction personnel is sent to the mobile control end through the 4G module. The mobile control end communicates with the 4G module through wireless signals. When it is necessary to remotely talk to the site through the mobile end, the audio information instruction of the mobile control end is transmitted to the central control module through the 4G module, and finally transmitted to the external security speaker to play the voice to the site. The motor 402 can make the device monitor and observe a larger range. The 4G module and the signal antenna 9 are used as a bridge to realize real-time communication between the mobile control end and the central control module. The mobile control end is used to receive the video information sent back by the camera in real time, and send real-time voice information to the security speaker 8 to realize the intercom function.
