Detailed Description

The invention is further described with reference to the drawings and the specific embodiments.

Before proceeding to the description of the specific embodiments, the following is described:

and the POE switch is connected with the POE system. The POE system is a power supply system or an active ethernet based on a local area network, and can provide power for a terminal device having a power receiving condition and perform data transmission. Specifically, in the POE system, different network devices set af, at, or bt protocols to solve the output power level according to different power levels, where the af protocol is 15.4W, the at protocol is 30W, and the bt protocol is 60W. The network dome camera has the characteristics of high instantaneous current, high power requirement of night infrared lamp starting and the like, equipment manufacturers are required to provide the highest data power of 40W, and the power line and the data line of the dome camera are mutually independent, so that the dome camera cannot be powered through a POE system.

For solving the problem that POE system can't provide working power supply for the ball-type camera, refer to FIG. 1, the utility model provides a power separator, including separator body 100, be equipped with PCB circuit board 110 on separator body 100, be equipped with signal processing module on PCB circuit board 110, this signal processing module can be for predetermineeing circuit structure or the circuit device that sets up, and its input is connected with the POE switch for power signal who sends the POE switch decomposes into power signal and data signal. Meanwhile, a network interface and a power interface are provided on the splitter body 100, and the power splitter is connected with the data end of the camera through the network interface and is connected with the power end of the camera through the power interface. Specifically, a data signal output by the signal processing module is sent to a data end of the camera through the network interface; and the power signal output by the signal processing module is sent to the power end of the camera through the power interface.

The working process of the embodiment is as follows: install the camera behind the default position, pass through power splitter with the camera and be connected with POE switch, and POE switch and POE headtotail. When the camera needs to work, the POE switch interacts with the POE system and acquires a corresponding signal from the POE system; then processing the signal into a signal which can be received by a power separator; the signal processing that power separator will follow the POE switch and acquire is power signal and data signal then, and the data end of data signal transmission to the camera through the network interface of self, in order to realize the interactive process of POE system and camera, and simultaneously, power end through the power source of self with power signal transmission to the camera, for the camera provides working power supply, thereby need not to set up working power supply alone for the camera, also need not to change the structural state of camera, can provide working power supply for the camera through the POE system, guarantee that ball-type camera normally works.

In some embodiments, since the camera may be installed at any position, the length of the network connection line on the power splitter may be insufficient, and thus the power splitter cannot be connected to the camera, in this embodiment, as shown in fig. 2, the power splitter further includes a network through head, which is used for performing extended use under the condition that the network connection line is not long enough, so as to ensure that the camera can be normally connected to the power splitter, and ensure normal transmission of data.

In some embodiments, when the camera is installed at a specific location, and the power splitter is located at a certain distance from the camera, which may result in that the power line on the power splitter is not long enough to provide working power for the camera, therefore, in this embodiment, as shown in fig. 1, a connection terminal is provided on the power interface, and is used for extending the power line through the connection terminal to connect with the power end of the camera when the power line is not long enough, so as to ensure that the camera can normally obtain the working power. In the present embodiment, the connection terminals include a dc connection terminal 120 and an ac connection terminal 130 to provide various power connection modes.

In some embodiments, for realizing the normal connection of power splitter and POE switch, still be equipped with the net twine on the splitter body, signal processing module passes through the net twine is connected with the POE switch to need not to change the connected mode of POE switch, can realize the connection process.

In some embodiments, since the camera is often required to be located outdoors for work, and the power splitter is also required to be installed outdoors along with the camera, in order to avoid damage to the components on the power splitter due to rain, as shown in fig. 3, the splitter body 100 is provided as a half-pack type housing. Set up to the half form of wrapping up in U type promptly, the installation sets up U type breach in the below for power separator is drenching with the rain in-process, and rivers shunt through U type structure, guarantee that rivers can't get into inside the separator body, thereby guarantee that inside device can not receive rain damage increase of service life.

In some embodiments, a plastic plate can be selected as the shell or a half of the plastic and fiber combination can be selected as the shell, so that the weight of the shell is reduced and the material cost is reduced while the waterproof function is realized.

In some embodiments, since the power separator needs to be provided with an external port, an opening structure must be provided on the housing, and in order to ensure that rainwater does not enter the interior of the housing when the power separator is used outdoors, as shown in fig. 3, the external ports 140 on the separator body 100 may be all provided at one end of the housing, and in the installation process, the end provided with the external port is provided below to prevent rainwater from entering the interior of the housing. Meanwhile, in order to avoid the non-working personnel from opening the shell, corresponding prompt words can be arranged outside the shell to prompt the non-working personnel.

While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
