Briefly talk about the application of remote monitoring system in construction site safety supervision?

DTMF interactive remote monitoring communication system is integrated into the intelligent building digital security disaster reduction system through the RS232 standard interface, forming a relatively independent subsystem.The subsystem DTMF intercontrol module is shown in Figure 3.

High alarm accuracy. The built-in intelligent algorithm of the intelligent video analysis system can eliminate the interference of climate and environmental factors, effectively make up for the shortcomings of manual monitoring, and reduce the overall false alarm rate and omission rate of the video surveillance system.

System Overview In order to standardize the construction site management of the construction industry, and realize the informatization of the supervision and management of the construction industry with the help of computer information network technology, strengthen the supervision means of law enforcement departments, and improve the scientificity, dynamics and accuracy of government macro-regulation.

Remote video monitoring function can be realized. Applying this function to the safety management of construction sites will inevitably greatly improve the management efficiency and improve the level of supervision. The operation of the monitoring system will enable construction enterprises to leap into a new management platform, strengthen government supervision, and grasp the dynamics of on-site construction in a timely and effective manner.

In terms of labor force management, the construction of "smart construction site" first realizes closed management of the construction site. Through gates and other equipment, it can effectively control the entry and exit of construction personnel, eliminate the entry of foreign strangers into the construction site, and make the construction site safer.

How to save the video surveillance of the construction site?

Save video through file transfer: If the monitoring device does not have a supporting mobile phone application, or if you want to save the surveillance video that has been stored on the computer, you can use the file transfer tool. For example, use a data cable to connect the mobile phone and the computer to copy the surveillance video to the mobile phone storage.

The first kind of access, the surveillance video is stored on the PC, in the folder defined by the monitoring program;In the latter two access methods, the video is stored in a specific location of the hard disk recorder, which can be copied with a USB flash drive and a mobile hard disk.

If you have a file to save in the monitoring software, save it directly. If not, record the screen. Most mobile phones have screen recording functions, and there are also screen recording software. The monitoring system is one of the most widely used systems in the security system. At present, the more suitable site monitoring system on the market is handheld video communication equipment, and video surveillance is now the mainstream.

composition structure of monitoring system

This question examines service facilities and management facilities. According to the function of the monitoring system, the monitoring system can be understood as composed of three major parts: information acquisition subsystem, information provision subsystem and monitoring center.

The hardware composition of the security monitoring system usually includes the following aspects: Camera: Installed in the area that needs to be monitored, and the monitoring is completed by capturing images. Video server: used to manage and store images or videos taken by cameras.

The video surveillance system consists of five parts: front-end acquisition, transmission, control, display and recording. Video cameraThe video image is transmitted to the control host through coaxial video cable, network cable and optical fiber, and the control host then distributes the video signal to each monitor and video equipment. At the same time, the voice signal that needs to be transmitted can be synchronously recorded into the video recorder.

Industrial controller: according to the division of each functional unit, data storage, processing and control; acquisition system: sensor (collection), network cable, converter (transmission), etc. Other auxiliary equipment: such as printer, sound and light alarm device, large screen display, external output extension, etc., which can be configured as needed.
