Detailed Description

Example 1: referring to fig. 1-2, an elevator safety rescue terminal based on POE power supply, including setting up terminal screen 1 in elevator car and setting up in POE switch 2 and the network connection device 3 on elevator car top, terminal screen 1 passes through the net twine and is connected with POE switch 2, and network connection device 3 is connected with POE switch 2, and POE switch 2 is connected with the supply socket electricity on the elevator car.

In this embodiment, POE switch 2 is used for supplying power to terminal screen 1 and network connection device 3 to carry out the internet access between network connection device 3 and the terminal screen 1, and POE switch 2 then directly gets the electricity from the supply socket on the elevator car, thereby reduced terminal screen 1 and network connection device 3's power supply line and network line, it is that the installation at elevator safety rescue terminal is more simple and convenient, its maintenance and maintenance process is also simpler. Specifically, the POE switch 2 is connected with the network connection device 3 and the terminal screen 1 through a network cable, and a network cable interface of the POE switch 2 can realize power supply and data transmission at the same time, so that the wire arrangement and wiring of the elevator safety rescue terminal on the elevator car are greatly reduced; wherein, POE switch 2 includes power pack 21 and POE exchange host computer 22, and POE exchange host computer 2 is connected with the supply socket electricity on the elevator car through the power pack.

Specifically, the terminal screen 1 is fixed in the elevator car, the POE switch 2 and the network connection device 3 are fixedly arranged on the top of the elevator car, and the POE switch 2 and the network connection device 3 can be fixed on the top of the elevator car by fixedly arranging a fixing support 4 for fixing the POE switch 2 and the network connection device 3 on the top of the elevator car, wherein the fixing support 4 can adopt a fixing support 4 with a protective cover 41, such as a metal support 42 with a hollowed-out structure at the lower end, the upper end is connected with the protective cover 41 through a hinge, a protective lock 43 is arranged between the protective cover 41 and the metal support 42, wherein the metal support 42 is fixed on the top of the elevator car through fastening screws, the POE switch 2 and the network connection device 3 are placed in the metal support, the protective cover 41 at the upper end of the metal support 42 is covered and locked by using the protective lock 43, wherein the protective cover 41 can protect the POE switch 2 and the network connection device 3 in the metal, meanwhile, the protection lock 43 can prevent an unskilled person from randomly opening the protection cover 41 to randomly modify the connection between the POE switch 2 and the network connection device 3.

Specifically, the network connection device 3 is a wireless network connection device, preferably, the wireless network connection device is a wireless network bridge CPE, and the wireless network bridge CPE is in wireless communication connection with a main machine box of the elevator machine room. The network connecting device 3 adopts a wireless network connecting device, so that the network wiring between the network connecting device 3 and a main machine box of an elevator machine room can be reduced, not only are maintenance parts reduced, but also the steps and cost of network connection are reduced.

Preferably, the terminal screen 1 is a POE power supply screen; the wireless bridge CPE adopts a POE powered wireless bridge CPE. When terminal screen 1 and wireless bridge adopt non-POE power supply, need install POE separator additional and supply power and transmit the net twine of data and convert the two groups of lines of supplying power respectively alone and transmitting data when the POE switch is exported, can make the wiring comparatively complicated, therefore, terminal screen 1 and wireless bridge CPE adopt the POE power supply, can use a net twine lug connection to terminal screen or wireless bridge CPE on the POE switch, thereby make wiring and winding displacement more simple and convenient, and improve the stability of connecting. Preferably, the terminal screen 1 is a POE powered LCD screen.

Specifically, terminal screen 1 inlays in elevator car and passes through the net twine with POE switch 2 at elevator car top through elevator car inlayer and be connected.

Of course, the above is only the preferred embodiment of the present invention, and the application range of the present invention is not limited thereto, so all the equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
