The present invention overcomes the deficiencies in the prior art, in television set, increase standby power supply module,, enable stand-by power supply and continue power supply if civil power disconnects suddenly, can store with some data of moving that guarantee TV, or more ongoing downloads or transmission work are proceeded.Technical scheme provided by the invention makes television set can keep normal operation under the situation of civil power outage, and the drawbacks such as loss of data of having avoided sudden power to cause have better met user's request.
Description of drawings
Fig. 1 is the TV Principles figure that the embodiment of the invention provides;
Fig. 2 is the schematic diagram of the control system that provides of the embodiment of the invention.
Embodiment
Technical scheme provided by the invention is: increase standby power supply module in television set, if civil power disconnects suddenly, enable stand-by power supply and continue power supply, can store, or more ongoing downloads or transmission work are proceeded with some data of moving that guarantee TV.
In order to make purpose of the present invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
TV Principles figure provided by the invention as shown in Figure 1, comprise power module 1, control system and the change over switch that is attached thereto, voltage stabilization and frequency stabilization device and standby power supply module 2, power module 1 all is connected with electric main with standby power supply module 2, and control system links to each other with change over switch; Wherein, standby power supply module 2 comprises storage battery, charger and inverter, change over switch is connected with storage battery with power module 1, electric main connects the storage battery input through charger, accumulator output end connects inverter, inverter output connects the voltage stabilization and frequency stabilization device, and the voltage stabilization and frequency stabilization device connects each functional module of television set, identifies with " load " among the figure.
Power module 1 just inputs to civil power the voltage stabilization and frequency stabilization device when electric main is normally imported, use through supply load behind the voltage stabilization and frequency stabilization device voltage stabilization and frequency stabilization, electric main also charges to storage battery internal battery group by charger simultaneously, and storage battery stores energy in the storage battery as energy storage component; When civil power interrupts (accident interruption) or input fault; control system control transformation switch switches; by storage battery to inverter power supply; inverter is with the power conversion of storage battery; provide 220 volts of alternating currents to the voltage stabilization and frequency stabilization device; the power supply that the voltage stabilization and frequency stabilization device provides inverter carries out offering behind the voltage stabilization and frequency stabilization load to be used, and makes load keep operate as normal and protects the load software and hardware not to be damaged.
Specifically, the control system schematic diagram as shown in Figure 2, specifically comprise CPU, detection module, input port I/O1 and output port I/O2, detection module is by judging to the detection of line voltage whether civil power is normal, testing result is converted to the input port I/O1 that is input to CPU after the digital signal, when detection module by input port I/O1 input be low level signal the time, the CPU of control system judges civil power outage this moment, gives change over switch by output port I/O2 output control signal.
Change over switch is connected with storage battery 5 with power module 1 simultaneously, be used for controlling the disconnection of power module 1 and the unlatching of storage battery, when change over switch receives the control signal of system system CPU by output port I/O2 output, the power supply of 1 pair of load of the module of then cutting off the electricity supply, start storage battery, by storage battery to the inverter output DC, inverter is with the power conversion of storage battery, provide 220 volts of alternating currents to the voltage stabilization and frequency stabilization device, the power supply that the voltage stabilization and frequency stabilization device provides inverter carries out offering the load use behind the voltage stabilization and frequency stabilization.
