Abstract
The utility model relates to a monitor device, more particularly to a monitor capable of uninterrupted power supply all alone in case of emergent power failure of a power supply system. The utility model comprises a main power source, a monitor, a chargeable battery and a power source converter, the main power source and the chargeable battery are respectively connected with the power source converter, the power source converter is connected with the monitor. The utility model has the beneficial effect of continuously working for 15 to 30 minutes by own power source on condition of emergent or artificial power failure in the power supply system, so as to guarantee a lasting monitor to emergencies.
Description
Technical field
The utility model relates to a kind of supervising device, can be by self uninterrupted power supply watch-dog under particularly a kind of electric power system burst powering-off state.
Background technology
Safety monitoring system is used in the place that safety problem may take place for bank, enterprise, megastore etc. usually, and when the electric power system that causes because of accident or artificial destruction monitoring goes wrong, supervisory control system is with ineffective, do not reach monitoring purposes, be unfavorable for situation analysis afterwards.
Summary of the invention
Deficiency in view of the prior art existence, the technical scheme of being taked is for achieving the above object: a kind of uninterrupted power supply watch-dog, comprise main power source, watch-dog, it is characterized in that: also comprise rechargeable battery and power supply changeover device, described main power source and rechargeable battery are connected with power supply changeover device respectively, and described power supply changeover device is connected with watch-dog.
The beneficial effects of the utility model are: when electric power system can work on 15-30 minutes by its own power source under because of the situation of emergency case or artificial destruction, to guarantee the lasting monitoring to accident.
Description of drawings
Fig. 1 is that circuit of the present utility model connects block diagram, and as Figure of abstract.
Embodiment
A kind of as shown in Figure 1 uninterrupted power supply watch-dog comprises main power source, watch-dog, also comprises rechargeable battery and power supply changeover device, and main power source, rechargeable battery are connected with power supply changeover device respectively, and power supply changeover device is connected with watch-dog.
Under the normal operating condition, use the main power source power supply, simultaneously rechargeable battery is charged.When main electric power system occurs can't continuing under the situation of normal power supply owing to accident or reason such as artificial, the power supply changeover device control circuit is selected supply power mode is switched to the reserve battery supply power mode at once, works on 15 to 30 minutes.
In addition, when using watch-dog on a large scale, may cause the watch-dog outage owing to the problem of monitor staff individual's carelessness or electric power system, at this moment, can utilize chargeable cell system that the watch-dog of power down is continued power supply, and sending chimes of doom, prompting monitor staff watch-dog main power source system goes wrong.
