Another of described driving relay J 2 synchronizeed the contact of same state with above-mentioned electric shock, be attempted by the warning input of outside network of network DVR, and its effect is in opening cabinet door, to start network hard disc video recording to carry out synchronized video recording.
In circuit of the present utility model, direction of current flow is shown in Figure 2.
Described official seal is preserved the explanation of supervision box electrical principle:
One, electric parts explanation:
1, stepping relay J1 is subject to the control of access control main frame, card reader is read a secondary card, access control main frame is just exported a pulse voltage, when stepping relay is often received a pulse voltage, contact J1-1, J1-2 just move once respectively, its output state is closure, disconnection, closed, disconnection ... move in circles with this, contact J1-1 and J1-2 are synchronous with state.One is connected on magnetic key operated lock power circuit, in a serial connection time-delay relay J3 loop.
2, time-delay relay J3 is for powering up timing closing type, delay time divides adjustable from 0-60, J3-1 is normal opened contact, and its effect is after machine box door is opened 60 minutes, move and start flashing light and buzzer, prompting administrative staff machine box door is not also closed, and official seal is not also put back in the groove position of cabinet.
3, drive relay J 2 for driving time-delay relay J3 work, J2-1 is normally closed contact, and J2-2 is normal opened contact, and this contact is attempted by the warning input of outside network hard disk video recorder, for gang video recording function.
4, drive relay J 4 for driving outside LED Down lamp, for it provides 220VAC alternating current, J4-1, J4-2 are Chang Kaiduan.
5, the contact of microswitch K is Chang Kaiduan, and when machine box door is closed, the depression bar stroke of microswitch is compressed, the Chang Kaiduan closure of microswitch, and depression bar has rebound effect, and in the time that magnetic key operated lock is decontroled machine box door, depression bar can flick machine box door.The top of depression bar is provided with a flat thin magnet, can hold cabinet door, at this moment between machine box door and casing, have an obvious gap, its object (1) is that this cabinet of prompting seal administrative staff is not also locked a door, official seal is not also put back in cabinet, (2) be to put stop machine case with the door open time, human body collides with.
6, infrared emission sensor is mounted in official seal groove position, and contact IR1-1, IR2-1, IR3-1 and IR4-1 are the normal-closed ends of contact, and when official seal is not put into Cao position, contact is open-circuit condition, and when official seal is put into, contact is closure state.The circuit of infrared emission sensor is referring to Fig. 3.
7, video camera power supply board is to use for external video camera provides 12VDC power supply, and plate is provided with eight pairs of lead-out terminals, for video camera or the equipment that need to access 12VDC power supply.
8, Switching Power Supply disposes reserve battery, can avoid machine box door in the time of civil power power-off surprisingly to open.
Two, operation principle:
Uncapping machine chamber door:
Under machine box door closed condition, by card brush card reader, the contact of monostatic relay is converted to open-circuit condition, magnetic key operated lock power-off, machine box door flick under the pressure of microswitch depression bar, take out after official seal, machine box door is closed to the position that can contact microswitch depression bar, at this moment machine box door is held by flat thin magnet, keep the prompting state partly covered, time-delay relay powers up and starts timing.When machine box door is opened, outside LED Down lamp united opening, carries out floor light to the scope of operation of affixing one's seal, and colleague's network hard disk video recorder is activated recording function, by scene video camera and just the picture of the video camera to the scope of operation of affixing one's seal be recorded on hard disk.
Door is opened rear " power work instruction " Ying Changliang, and " electric lock power supply instruction " lamp extinguishes, and " prompting of not closing the door " lamp does not work.
Overtime alarm:
Open after 60 minutes when machine box door, " prompting of not closing the door " buzzer ring of glittering while of lamp, points out administrative staff's machine box door also not close by acousto-optic mode, and official seal is not also put back to the groove position in cabinet.
Close machine box door:
Put back to behind groove position at all official seals, after first by card brush card reader, seeing that " electric lock power supply instruction " lamp is lighted, push hard press chamber door to closing position, at this moment magnetic key operated lock by door firmly adhesive live.After cabinet every is closed, outside LED Down lamp is closed simultaneously, and network hard disc video recorder also stops recording function.
Machine box door is closed rear " power work indicator lamp " should keep Chang Liang, and " electric lock power supply instruction " lamp should keep Chang Liang, and " prompting of not closing the door " lamp should extinguish.
