The following describes the implementation of this creation through specific examples. Those skilled in the art can easily understand other advantages and effects of this creation from the content disclosed in this manual.

Referring to FIG. 1 to FIG. 3, this is an embodiment of the street lamp data and power transmission device 100 of the present creation. The first diagram is a schematic diagram of the appearance of a street lamp, the second diagram is a schematic diagram of the appearance of a lamp, and the third diagram is a block diagram of an architecture. In this embodiment, the street light data and power transmission device includes a light pole 101, at least one electronic device 2 and a PoE switch 3.

PoE switch 3 is a technology for power over Ethernet (PoE). In Ethernet, the technology of transmitting power and data to other devices through twisted pair wires at the same time. This technology can be used in devices such as internet phones, wireless base stations, web cameras, computers, etc. Electronic equipment powered by Ethernet can be used without additional power sockets, so the time and cost of configuring power cords can be saved, and the cost of the entire device system is relatively reduced. PoE switch 3 facilitates remote central monitoring. PoE technology adds power transmission capability to traditional Ethernet networks. It can transmit power to devices on Ethernet cables in existing or new data cable infrastructure.

PoE switch 3 has an Ethernet network switch (PoE Network Switch), which transmits power directly to the Ethernet power-generating product (PoE Splitter) through an Ethernet cable. The Ethernet cable is transmitted to a non-PoE device, which includes wireless APs, CPEs, routers, etc.

At least one electronic device 2 is mounted on the light pole 101, and the PoE switch 3 is installed in the light pole 101. The PoE switch 3 includes at least one port 4 and two ends of the at least one cable 5 are connected to the at least one electronic device 2 Data and power are transmitted to at least one port 4.

The PoE switch 3 is connected to a switching backup module 6 and automatically switches to an LTE module 96 to transmit data when at least one cable 5 is interrupted.

At least one electronic device 2 is a camera 21 (image capture device), a temperature and humidity detector 22, an advertising machine 23, or a wireless network base station 24. The image capture device is used to install on the light pole 101 of the street light to capture the road conditions in the vicinity of the street light. The image capture device is electrically connected to the digital communication interface. The digital communication interface can be directly provided through Ethernet power technology (PoE). The operating power of the image capturer, without the need for additional DC converter settings, can simplify circuit complexity and reduce costs. Therefore, a remote host can receive the image captured by the image capture device from the power line data communication unit to achieve the real-time road condition monitoring effect.

In some embodiments, the street light data and power transmission device further includes a plurality of electronic devices 2, which are respectively a camera 21, a temperature and humidity detector 22, an advertising device 23, and a wireless network base station 24.

The power line is used as a communication channel, and PoE is a complementary technology that can transmit power over Ethernet data cables. The simultaneous application of these two technologies in data and power networks can be more cost-effective, more flexible, and achieve optimal results. PLC technology uses existing low-frequency (50/60 Hz) power lines to transmit broadband network messages. Compared to ADSL using telephone lines, general applications can be divided into two types. FTTx uses optical fiber lines, and Cable Modem uses cable TV lines. . With power line communication technology, there is basically no need to re-lay network lines, and the area covered by power lines is much larger than that of other types of carriers.

The PoE switch 3 is further connected with a switching backup module 6. When the at least one cable 5 is interrupted, it automatically switches to an LTE module 96 to transmit data. The PoE switch 3 originally transmits data through a transmission line or optical fiber. When the transmission line or Optical fiber dragging is broken or the equipment room is interrupted.
