Description
Technical field
The utility model relates to a kind of equipment cabinets.
Background technology
Existing equipment cabinets only is the effect of playing the protection box equipment by door lock, because front end chamber external equipment place that cabinet is put is remoter sometimes; like this; just given some lawless person's opportunities, machine box door is usually prized, and causes the stolen phenomenon of equipment to happen occasionally.How to improve alarm mechanism, it is the problem that needs solution at present that the effect cabinet of taking precautions against and deterring is played in theft.
The utility model content
At the problem that prior art exists, the purpose of this utility model is to overcome above-mentioned shortcoming, when a kind of machine box door is provided by unnormal unlocking, and the equipment cabinets that has warning function and can in time inform the center operator on duty with anti-theft alarm function.
The technical scheme in the invention for solving the technical problem is: a kind of equipment cabinets with anti-theft alarm function, comprise casing, be provided with gate and wicket at described casing, greatly and on the inside casing of wicket a state detector is installed described, described door state detector comprises two microswitches, relay, alarm and I/O integrated circuit board, described two microswitches are installed in respectively on the inside casing of gate and wicket, the contact switch that is arranged on the wicket inside casing is that wicket is closed the closing of contact, the contact switch that is arranged on the gate is that the gate closes the closed contact disconnection, the series connection of two microswitches also is connected with the coil of relay, often open electric shock for two of relay and be connected with the I/O integrated circuit board with alarm respectively, the I/O integrated circuit board is connected with command centre.
Described equipment cabinets with anti-theft alarm function, described microswitch are arranged on the inside casing of large and small door.
Described equipment cabinets with anti-theft alarm function, described alarm are audible-visual annunciator.
Described equipment cabinets with anti-theft alarm function, described alarm are arranged on the inboard or the outside of an inside casing.
The utility model because, greatly and on the inside casing of wicket a state detector is installed described, the door state detector comprises two microswitches that are installed on gate and the wicket, the contact switch that is arranged on the wicket inside casing is that wicket is closed the closing of contact, the contact switch that is arranged on the gate is that the gate closes the closed contact disconnection, like this, directly opening under the situation at gate, the circuit that is connected with relay coil is communicated with, two normally opened contacts of relay are owing to be connected with command centre with alarm respectively, at this moment alarm sends alerting signal, and command centre knows that in time the gate is illegally opened, both can play the effect of drawing back the robber with fear, and inform in time also that center operator on duty, somewhere equipment have to be prized, stolen situation.
