TD-LTE video communication controller with UPS

Abstract

The invention relates to a TD-LTE video communication controller with a UPS. A UPS module is arranged inside the TD-LTE video communication controller. The UPS module comprises a power supply port, a power source rectifying circuit, a DC-DC switching circuit, a battery pack management circuit and a synchronous voltage reduction circuit which are sequentially connected, wherein the power source rectifying circuit is used for rectifying a power source, the DC-DC switching circuit is used for adjusting a voltage, the battery pack management circuit is used for storage electricity, a battery chip is arranged inside the battery pack management circuit, and the synchronous voltage reduction circuit is used for reducing the voltage to be a working voltage. The synchronous voltage reduction circuit outputs the working voltage to the controller. When an electric supply is powered up, the electric supply is subjected to voltage transformation through a switching power supply and then supplies electricity to the controller and charges the battery chip through the power supply port, the power source rectifying circuit, the DC-DC switching circuit, the battery pack management circuit and the synchronous voltage reduction circuit. When power failure happens to the electric supply, the battery chip is started, and voltage outputting is conducted through the synchronous voltage reduction circuit to supply electricity to the controller. According to the TD-LTE video communication controller with the UPS, the UPS module is integrated in the controller, seamless switching can be achieved when the electric supply is disconnected, the TD-LTE video communication controller is composed of an integrated chip and a discrete device, so that the integration level is high, and cost is low.

Description

technical field [0001] The invention relates to the field of video monitoring, and more specifically, relates to a TD-LTE video communication controller with UPS. Background technique [0002] In the field of video surveillance, in order to ensure the uninterrupted operation of equipment, UPS power supply is generally used. The current technical solution is to separate the design of UPS and video monitoring equipment. Since the UPS equipment is relatively heavy, the installation of equipment and the construction of power supply lines are relatively cumbersome, and the installation location is also subject to certain restrictions. Such as figure 1 As shown, its working principle is: when the mains power supply is used, the SDI camera collects the image and transmits it to the sending end of the SDI fiber optic transceiver through the coaxial cable. The fiber optic transceiver converts the SDI signal into an optical pulse signal, and passes The optical fiber is transmitted t...
