Description

The cartridge box control device

Affiliated technical field

The utility model relates to a kind of cartridge box control device, is suitable for People's Armed Police's janitor's room is got bullet to the post control.

Background technology

The post of People's Armed Police is provided with cartridge box now, sentry's bullet on duty at ordinary times separates, when running into emergency and need get bullet, for consideration to safety factor, all need the sentry to send request to janitor's room, through janitor's room examine approve and agree after, and open cartridge box, the sentry can get bullet.Because general post and janitor's room distance are far away, so between post and janitor's room signal line and control circuit must be arranged technically.The control system of present stage by place the control cabinet in the janitor's room and place the post cartridge box and between control line form, can finish the setting task, but exist following shortcoming: in running order during the long-term standby of element on the control cabinet, the component aging degree is fast, makes failure-frequency increase greatly; Directly controlling the other side's relay mutually with 12V voltage between janitor's room and the post realizes reporting to the police and unblanking, when 2 distances are far away, must increase the standard wire lattice ability operate as normal of connecting line, therefore relatively stricter to the requirement in line footpath, otherwise when 2 distances are far away, because voltage loss makes control lose efficacy, and exists potential safety hazard; Be exactly that the security of system performance is not high in addition, the technical leak that exists is easy to realize that non-program gets the purpose of bullet; In addition, the circuit between janitor's room and the post is that one eight core industrial siding connects, the cost height that circuit drops into.

Summary of the invention

The purpose of this utility model provides a kind of security performance height, and cost is low, and fault rate is low, repair and maintenance easily the cartridge box control device to remedy the deficiency of prior art.

The technical solution adopted in the utility model is: janitor's room is provided with control cabinet, and the post is provided with cartridge box, and lock is arranged on the cartridge box; Holding wire and ground wire are arranged between janitor's room and the post, and the power supply at post is connected on the transistor base in the control cabinet by door switch, alarm switch, relay, holding wire; Between the base stage of relay and unlatching triode connecting line is arranged; The power supply at post is opened relay and can be unblanked by opening the colelctor electrode that relay was connected and opened triode; In control cabinet, the control triode is connected with alarm lamp and buzzer by control relay; The unlatching switch is arranged between janitor's room power supply and holding wire; On the janitor's room power supply reset switch is arranged.

The beneficial effects of the utility model are: complete machine duty standby current is little, has only originally 1/tens, and most of element only just works when reporting to the police, and all is in the stand-by operation state at ordinary times, and fault rate is reduced.Increase the application life of complete machine; After having overcome the atom cartridge box and breaking down, janitor's room continues the phenomenon of reporting to the police always; Easy to maintenance; Greatly reduce the possibility that illegal program is got bullet under the situation of not reporting to the police; In addition because the utility model uses low-voltage, little electric current to replace original 12V voltage and bigger operating current, reduced the loss on the circuit, the far and near factor of distance does not constitute the influence to native system work basically, so can use common two heart yearns, line cost reduces greatly.

Description of drawings

Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the electrical block diagram of the utility model embodiment;

Fig. 3 is the structural representation of the embodiment of two groups of controls of use of the present utility model.

The specific embodiment

Embodiment:

Holding state at ordinary times, cartridge box 1 and control cabinet 2 insert civil power simultaneously, and the door of cartridge box 1 is closed interlock door switch K ₄Closure, resistance R ₅R ₆The about 3V of branch pressure voltage is by door switch K ₄, switch P ₂, relay J ₂To A ₁Point is again by A point, the switch P of small-signal connecting line 3 to control cabinet 2 ₄, resistance R ₃Arrive triode Q ₁Base stage, will make triode Q like this ₁Conducting makes control triode Q simultaneously ₂Base stage be in electronegative potential, so control triode Q ₂End control relay J ₁No operating voltage, control cabinet 2 is in holding state.At this state, has only triode Q ₁In running order, all the other elements are not all worked.

When the sentry need get bullet, just press the K switch on the cartridge box 1 ₅, switch P ₂Disconnect, simultaneously switch P ₁Conducting makes relay J ₂Get electric upset contact, A ₁Point and resistance R ₈Connect, make and open triode Q ₃Be ready.In relay J ₂When getting electric upset contact, also make A ₁Point loses voltage, thereby makes A point no-voltage, makes triode Q accordingly ₁Lose base voltage and end control triode Q ₂Base potential therefore rise, so control triode Q ₂Conducting makes control relay J ₁Get electric work, double-contact P ₃, P ₄Transposition simultaneously, P ₃Straight-through 12V power supply makes the unlatching K switch ₃On lamp bright, simultaneously buzzer YD pipes, and has realized sound and light alarm.The process of filing an application to janitor's room in the post has just been finished in above-mentioned action, and whole process is very simple, and the sentry only needs an actuation of keys to realize.

The person on duty receives after the alarm signal, only needs in luminous unlatching K switch ₃On click, the 12V voltage of control cabinet 2 is from opening K switch ₃, contact P ₄, A point, A ₁Point, resistance R ₈To opening triode Q ₃Base stage, make and open triode Q ₃Conducting so just makes the unlatching relay J ₃Obtain the 12V voltage at post, its closing of contact has been finished unlocking action, and the sentry just can open the door and get bullet.

After the sentry gets the bullet release, close the door of cartridge box 1, then door switch K ₄Closure disconnects K again ₅, make P ₁Disconnect P ₂Closure, the A point is recaptured voltage.The person on duty presses the K that resets ₁, control relay J ₁Dead electricity quits work, P ₃, P ₄Reply original state.

Above-mentioned is the process of a cartridge box 1 of a control cabinet 2 controls, and both only need a holding wire and two lines of a ground wire just can control easily.

When the post has a plurality of cartridge boxes 1 to need control, just can on the wiring board of the control cabinet 2 of janitor's room, set up several groups of circuit and get final product, and connection line can shared ground wire, controlledly just think that how case only needs the increase single lines so set up one.In practice, for fear of the appearance that the situation of janitor's room operate as normal occurs influencing because circuit or cartridge box fault cause buzzer not stop to report to the police, the spy has set up selector switch K ₂, close K ₂Buzzer that can that road of closing fault and do not influence the operate as normal on other several roads.If the circuit on a certain group of control panel damages, just can close the selector switch K of that bad group ₂, open one group standby selector switch K ₂, one group that directly plug-in unit is inserted gets final product.
