Detailed Description
Embodiments of the construction site safety state detection system according to the present invention will be described in detail with reference to the accompanying drawings.
Construction site (construction site), also called as construction site, short for site, is a site in which civil engineering is being developed, and the area is often enclosed by coamings, wire netting or enclosing walls, which restrict the access of people, materials, machinery and vehicles. And a property management manager keeps watch. Entry and exit may require registration of identity, wearing of safety helmets, etc.

In addition, pstn (public Switched Telephone network) defines: the PSTN provides an analog private channel, and the channels are connected through a plurality of telephone switches. When two hosts or router devices need to be connected through PSTN, a Modem (Modem) must be used on the network access side (i.e., the user loop side) at both ends to implement analog-to-digital, digital-to-analog conversion of signals. From the perspective of the OSI seven-layer model, the PSTN can be viewed as a simple extension of the physical layer, without providing services such as flow control, error control, etc. to the user. Furthermore, since the PSTN is a circuit-switched approach, a path is set up until released, and its full bandwidth can only be used by devices at both ends of the path, even though there is no data to transfer between them. Therefore, this circuit-switched approach does not achieve full utilization of network bandwidth. The network interconnection is exemplified by the PSTN. The following is an example of a network interconnection connecting two local area networks via a PSTN. In the two local area networks, each router is provided with a serial port connected with a Modem, and the Modem is connected with a PSTN, thereby realizing the interconnection of the two local area networks.
