The utility model relates to a power unit for multi-channel video surveillance equipment. The power unit includes a power input module and an interface module. The power input module includes a power supply and a main binding post. The power supply supplies and outputs power to the main binding post by setting a transformer. The main binding post is connected in series with a fuse device that can be blown, and connected in series with a power supply switch and a piezoresistor. The piezoresistor is connected in parallel with a green LED light. The interface module is connected to the power input module, and includes two rows of sub binding posts connected with a camera power supply line of terminal equipment. Power outputs of different poles are divided into two rows; each channel is first connected in series with a self-resetting fuse, then connected onto the sub binding posts of the camera line and meanwhile connected in parallel with a red LED indicator. According to the utility model, the operation stability and maintenance of a camera are greatly improved.
Description
Technical field
The utility model relates to a kind of video camera of safety defense monitoring system and the electric supply installation of warning device.
Background technology
Along with the development of safety-protection system, the application of digital security, concentrates tandem by the network switch to the connection of web camera, and tackling mutually video camera power supply also has more centralized management.Conventionally, comprise digital camera system, the camera power supply of supervisory control system is supplied with two kinds of modes, the one, the independent transformer of each video camera is powered, thisly can guarantee that each road video camera electric power system is unaffected each other, but power transformer quantity, outlet are many, equipment disperses to cause and safeguards and management inconvenience; Another kind is that the power supply collection of multichannel video camera carries out and connects power supply at a jumbo transformer, thisly can concentrate on any and manage, but the power supply of video camera all can impact the video camera of doubling mutually, also can not confirm whether current power supply unit has pair video camera power supply output.
Summary of the invention
In order to overcome the video camera power supply management deficiency of safety-protection system; the utility model provides a kind of electric supply installation of multi-channel video monitor equipment; this device can not only provide the centrally connected power supply of multichannel video camera simultaneously; can also make to power between mutual circuit (video camera supply line) unaffected; the indication of Neng Duimei road video camera line powering output simultaneously and Self-resetting safeties, and increase surge protection measure and resistance to thunderbolt ability.
The utility model solves the technical scheme that its technical problem adopts:
A kind of electric supply installation of multi-channel video monitor equipment, this device comprises Power Entry Module and interface module, Power Entry Module comprises power supply and total binding post, power supply outputs to total binding post by transformer-supplied is set, the fuse unit of a fusible of total binding post series connection, and connect a mains switch and a varistor, varistor green LED lamp in parallel; Described interface module is connected to Power Entry Module, interface module comprises the dividing binding post that two rows are connected with the video camera supply line of terminal equipment, the power supply output of different poles is divided into two rows, the connection on each road Self-resetting fuse of first connecting, be connected on the dividing binding post of video camera circuit a red LED indicator light simultaneously in parallel.
The utility model is owing to having adopted above-mentioned technical scheme, and transformer-supplied outputs to a power supply connection box, a) on device, is furnished with corresponding power supply input indicator, defines the power supply output of indicating transformer, the operating state of indicating transformer directly perceived.B) this installs the relatively independent binding post of discrete multichannel, solved very difficult multi-route together and connect and be pressed onto on binding post, guarantee that each route all can be pressed onto on binding post completely.C) power supply, to independent binding post post, is multichannel equipment power supply output, and resettable fuse is equipped with on each road, while having fault or short circuit on other route road like this, can not affect the power supply that outputs to other pipeline equipment, can guarantee the normal work of other pipeline equipment.D) simultaneously each road output is with LED light, as line short or load excessive, Self-resetting fuse disconnects, and corresponding indicator light do not work, and is convenient to safeguard supply line and investigation fault message.E) power supply input is furnished with varistor, effectively ability and the resistance to thunderbolt ability of surge current suppression.
The power supply output of each road adopts Self-resetting fuse, and considering that self-healing fuse has can self-righting performance, can reduce the number of times of reprocessing and serving of product, thus the convenience that reduces costs and safeguard.Because self-healing fuse can move within the extreme time, to protect, in circuit, some,, than more sensitive resistance, are improved the reliability of video camera and useful life again.Simultaneously the power consumption of self-healing fuse is very low, there will not be the phenomenon of extreme heating and consume the energy under normal current operating state.Resistance very little (conventionally only having a little Europe at zero point) thereby can not form oscillating circuit under running current.
The beneficial effects of the utility model are, this device can effectively solve video camera (also can be used for other weak electricity system equipment power supply) the equipment centrally connected power supply outgoing management problem in engineering application, but mutually the output of supply line is independent of each other mutually, the wiring problem of project installation, power supply output to equipment and confirm indication, the stable operation and the maintenance work that have greatly improved video camera.

Fig. 2 is the line power supply winding diagram (contrast) of conventional power supply output.
Fig. 3 is the line power supply winding diagram (contrast) of conventional power supply output.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Based on video camera power demands, the power consumption of the video camera of rifle formula or half ball type generally has: 4 watts of left and right of simulation, 8 to 10 watts of numerals; The indoor type power consumption meeting of ball machine is 20 watts of left and right, 50 watts of outdoor left and right.In conjunction with the specification size of transformer (24VAC), and chest size is installed, so our design is selected at No. 9 video camera power supply output devices, transformer is chosen in 150 watts of left and right, and patch board device designs in 15 centimeter length, 9 centimetres of wide left and right.
As shown in Figure 1, a kind of electric supply installation of multi-channel video monitor equipment, this device comprises Power Entry Module and interface module, Power Entry Module comprises power supply 1 and total binding post 2; Power supply 1 outputs to total binding post 2 by transformer-supplied is set, the fuse unit 3 of a fusible of total binding post 2 series connection, and connect a mains switch 4 and a varistor 5, fuse unit 3 coordinates varistor 5, suppress surge and thunderbolt ability, can guarantee physically in complete deenergization output.Described varistor 5 green LED lamp 6 in parallel, normally inputs as the voltage of indicating transformer.Described interface module is connected to Power Entry Module, interface module comprises the dividing binding post 9 that two rows are connected with the video camera supply line of terminal equipment, the power supply output of different poles is divided into two rows, the connection on each road Self-resetting fuse 7 of first connecting, be connected on the dividing binding post 9 of video camera circuit, whether a red LED indicator light 8 simultaneously in parallel, indicate the voltage of current circuit normally to export.Total so total output video camera 10 has 9 pairs for electric wiring terminal, to there being 9 red Voltage-output indicator lights, has 9 independently Self-resetting fuse units simultaneously.
