[0017] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0018] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a device for powering a camera via a network cable, including a power supply module 1 and several power receiving components 2, the power receiving component 2 includes a power receiving module 21 and a camera 22, the output end of the power supply module 1 is connected to the input end of the power receiving module 21 through a first network cable 3, the power receiving module 21 is installed in the housing of the camera 22, and the output end of the power receiving module 21 is connected to the camera 22 through a second network cable 4, the power supply module 1 is used to power the power receiving module 21, and the power receiving module 21 is used to power the camera 22.
[0019] Specifically, the power supply module 1 can receive high input voltages from new energy vehicles and has a wide input voltage range. While conventional POE power supplies convert AC to DC, this power supply module 1 converts DC to DC and is specifically designed for data acquisition in new energy vehicles. The power supply module 1 can power four power receiving components 2 and supports both automatic mode and manual control mode using I2C commands. Each output can be turned on and off using I2C commands, and the camera 22 that requires power can be selected using manual control mode, reducing energy consumption in new energy vehicles. The power receiving module 21 is a miniaturized module that can be integrated into the housing of the camera 22. The output of the power receiving module 21 is connected to the camera 22 via a second network cable 4. The power supply module 1, the power receiving module 21, and the camera 22 are connected via a first network cable 3 and a second network cable 4. The camera 22 can be installed in various locations both inside and outside the new energy vehicle, enabling it to better collect data from around or within the vehicle.
[0020] The data acquisition module 5 of the new energy vehicle is connected to the power supply module 1, which is then connected to the power receiving module 21 via a first network cable 3. The power receiving module 21 is then connected to the camera 22. After power is applied, the camera 22 is tested for proper operation. Then, I2C commands are written to control the output of one or more cameras 22 and record their normal operation.
[0021] Experiments have shown that after successful recognition between the power supply module 1 and the power receiving module 21, the power supply module 1 successfully supplies power to the camera 22 through the power receiving module 21, and the data collected by the camera 22 is transmitted to the data acquisition module 5. The manual control mode uses I2C commands to control the success of the on / off verification of one or more cameras 22.
[0022] The device, which powers cameras via a network cable, operates in three steps: detection, classification, and power supply. After classification, the power supply module 1 outputs 44-57V DC power to the power receiving module 21 and verifies that the power receiving module 21 does not exceed the power requirements determined during the classification process. If the power receiving module 21 is overloaded or short-circuited, the power supply module 1 stops supplying power and enters the detection phase. This device verifies that the connected camera 22 meets standards, ensuring proper operation and preventing damage.
[0023] In the above structure, a first network cable 3 is used to connect the power supply module 1 and the power receiving module 21, so that the power supply module 1 supplies power to the power receiving module 21, and the power receiving module 21 supplies power to the camera 22. This device, which supplies power to the camera 22 via a second network cable 4, does not require an additional power cable, saving costs and significantly reducing wiring complexity. It also meets the various installation requirements of the camera 22, both inside and outside the new energy vehicle.
[0024] like Figure 1 and Figure 2 As shown, in one embodiment, the device for powering the camera via a network cable further includes a data acquisition module 5, which is connected to the power supply module 1 and is configured to output data and supply power to the power supply module 1. The data acquisition module 5 facilitates data transmission and power supply to the power supply module 1, enabling the power supply module 1 to perform data transmission and power supply operations on the power receiving module 21 and the camera 22.
[0025] like Figure 3 As shown in one embodiment, the power supply module 1 of the device for powering a camera via a network cable includes a first interface circuit 11, a first power circuit 12, and a first network transformer 13. One end of the first network transformer 13 is connected to the first network cable 3, and the other end of the first network transformer 13 is connected to the first interface circuit 11. A magnetic coil group is provided on the side of the first network transformer 13, and the center tap of the magnetic coil group is connected to the first power circuit 12. The first power circuit 12 of the power supply module 1 is connected to the high input voltage of the new energy vehicle, with an input voltage of 2000V, which can accept a wide range of input voltages. Compared to POE power supply, which converts AC to DC, this power supply module 1 converts DC to DC. The DC conversion circuit can convert the voltage of the new energy vehicle to the voltage required by the communication protocol. This device not only accepts a wide input voltage range but also performs voltage shunting for the power receiving component 2, ensuring that the power of the power receiving component 2 meets the power requirements.
[0026] like Figure 3As shown in one embodiment, the power receiving module 21 of the device that supplies power to the camera via a network cable includes a second interface circuit 211, a second power circuit 212, and a second network transformer 213. One end of the second network transformer 213 is connected to the first network cable 3, and the other end of the second network transformer 213 is connected to the camera 22 via the second network cable 4. The two side ends of the second network transformer 213 are respectively connected to the second interface circuit 211 and the second power circuit 212. The second network transformer 213 of the power receiving module 21 is connected to the first network cable 3 and the second network cable 4, eliminating the need for an RJ45 port. The second network transformer 213 then divides the voltage and signal frequency. The second interface circuit 211 and the power supply module 1 perform a handshake protocol, and the power circuit supplies power to the camera 22, which collects data from both the outside and inside of the new energy vehicle. The configuration of this power receiving module 21 not only provides power and data transmission to the camera 22, but also reduces power cables and wiring difficulties, saving costs.
[0027] like Figure 3 As shown, in one embodiment, the second power supply circuit 212 of the device for supplying power to the camera via the network cable includes a rectifier and filter circuit. The rectifier and filter circuit is configured to perform rectifier power supply.
