Abstract
The utility model relates to a continuous power supply system of a monitoring camera. The technical scheme adopted by the utility model is that the power supply system comprises a charge-discharge power supply, a battery and a camera; the output/input end of the charge-discharge power supply is connected with the input/output end of the battery, and the output end of the charge-discharge power supply is connected with the input end of the camera. Under the premise that the safety precaution system is complete, compared with the method of UPS (uninterruptible power supply) centralization power supply, the continuous power supply system effectively reduces the construction difficulty, greatly saves cable laying, and saves the money. When the commercial power is in power failure, the continuous power supply system ensures the normal working of the camera for some time.
Description
Technical field
The utility model belongs to the electric power system field, relates to the electric power system of powering continuously to monitoring camera particularly.
Background technology
In current protection and monitor field, usually the way of employing UPS centrally connected power supply guarantees the continuity of the power supply of rig camera, in the work progress of centrally connected power supply, need to lay a large amount of cables, difficulty of construction strengthens, and the misoperation of other power consumption equipments (misconnection such as large power supply is gone into) may make the load of ups system strengthen, the instability that causes whole electric power system influences fail safe simultaneously.
Summary of the invention
In order to overcome the above problems, it is a kind of simple in structure that the utility model provides, and safety is easy to install, the uninterruptible power supply system of the monitoring camera that can power continuously.
The utility model is achieved by the following technical solution, and a kind of uninterruptible power supply system of monitoring camera is characterized in that: form by discharging and recharging power supply, storage battery and video camera; Output/the input that discharges and recharges power supply links to each other with the I/O end of storage battery, and the output that discharges and recharges power supply is connected with the input of video camera.
The beneficial effects of the utility model are: it is that 220 volts of interchanges, output are generally 12 volts of direct currents that the utility model discharges and recharges the power supply input, can be charge in batteries, is the video camera supplying DC power source simultaneously.When accumulator electric-quantity was saturated, charging was cut off automatically, was the video camera power supply by discharging and recharging power supply.When at mains failure, discharge and recharge power supply and switch to discharge condition, be the video camera power supply by storage battery; When the city power recovery powers, discharge and recharge power supply and automatically switch to and be battery state of charge.The utility model can effectively reduce difficulty of construction guaranteeing to compare the way of UPS centrally connected power supply under the complete prerequisite of safety and protection system, saves cable laying in a large number, the saving fund.Under the situation of mains failure, can also effectively guarantee video camera operate as normal a period of time.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of uninterruptible power supply system of monitoring camera: form by discharging and recharging power supply (1), storage battery (2) and video camera (3); Output/the input that discharges and recharges power supply (1) links to each other with the I/O end of storage battery (2), and the output that discharges and recharges power supply (1) is connected with the input of video camera (3).
Discharge and recharge power supply and can adopt the FC-903 charge-discharge circuit.
During installation, the input that discharges and recharges power supply can insert mains supply nearby, compares the way of UPS centrally connected power supply and saves a large amount of cable amounts of laying, and reduces difficulty of construction, reduces the engineering input.Output is generally 12 volts of direct currents, is charge in batteries, is the camera power supply power supply simultaneously, and the output of video camera is connected with video output device; When accumulator electric-quantity was saturated, charging was cut off automatically, stops to be charge in batteries, discharged and recharged power supply and continued as the camera power supply power supply; When mains failure, discharge and recharge power supply and automatically switch to discharge condition, battery discharging continues as video camera power supply is provided; In city power recovery when power supply, discharge and recharge power supply and automatically switch to charged state, is charge in batteries, and provide power supply for video camera.
Claims (1)
