Abstract
The utility model relates to a self-maintained power supply type camera device which comprises a camera and a power supply control circuit and is characterized in that: the power supply control circuit consists of a power supply switching circuit which is separately connected with a main power supply and a standby battery; and the output end of the power supply switching circuit is connected with a camera. The standby battery can be a nickel-metal hydrid battery. In case of a sudden power cut, the utility model can switch to the standby battery through the power supply control circuit for maintaining a continued camera function for about 30 minutes, thereby ensuring continuous monitoring on an emergency. The utility model is simple in structure, convenient in use, reliable in performance and wide in application range.
Description
Technical field
The utility model relates to a kind of camera head, particularly a kind of self-holding operated type camera head.
Background technology
At present, in order to ensure nation's security, in the financial field, military scientific research, large enterprise and public place, market, hotel all be provided with the installation safety monitoring system usually.Supervisory control system, especially when some special occasions use, the continuation of its course of work is very important, even some situation takes place also should be able to work on a period of time, to guarantee the integrality of incident record, like this can be for the analysis and the processing of situation provide the valuable firsthand information afterwards.If but when causing the power pack of supervisory control system to go wrong because of accident or artificial destruction, whole monitoring system is unfavorable for afterwards situation analysis and correct the processing with ineffective.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of simple in structure, dependable performance is provided, and can continue to keep the self-holding operated type camera head of camera function under the sudden power situation by power autonomous switching.
The technical scheme that the utility model adopted is for achieving the above object: a kind of self-holding operated type camera head comprises camera and power control circuit; It is characterized in that power control circuit connects main power source respectively by power supply switch circuit and reserve battery is formed, the power supply switch circuit output connects camera.
Described reserve battery can adopt Ni-MH battery.
The beneficial effects of the utility model are: simple in structure, dependable performance.Can under the sudden power situation, switch to the reserve battery power supply, continue to keep camera function work about 30 minutes, to guarantee lasting monitoring to accident by power control circuit.
Description of drawings
Fig. 1 is the utility model circuit side connector block diagram.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
As shown in Figure 1, a kind of self-holding operated type camera head relates to closed monitor system (CCTV) and power driving circuit, comprises camera and power control circuit; It is characterized in that power control circuit connects main power source respectively by power supply switch circuit and reserve battery is formed, the power supply switch circuit output connects camera.
Described reserve battery can adopt Ni-MH battery, as the 1AH Ni-MH battery.
Under the camera head normal operating conditions, use the main power source power supply, simultaneously to standby Ni-MH battery charging.Can't continue under the situation of normal power supply owing to reasons such as accident or artificial destructions when main electric power system occurring, power supply selects control circuit at once supply power mode to be switched to the reserve battery supply power mode, and work on 15 to 30 minutes (according to camera model and occupation mode thereof), to guarantee lasting monitoring to accident.
Above-mentioned with reference to embodiment to the detailed description that the operated type camera head of controlling oneself carries out, be illustrative rather than determinate, therefore in the variation and the modification that do not break away under the utility model general plotting, should belong within the protection range of the present utility model.
Claims (2)
1, a kind of self-holding operated type camera head comprises camera and power control circuit; It is characterized in that power control circuit connects main power source respectively by power supply switch circuit and reserve battery is formed, the power supply switch circuit output connects camera.
2, self-holding operated type camera head according to claim 1 is characterized in that described reserve battery can adopt Ni-MH battery.
