Fig. 3, shown in 4, the utility model in use, 220V AC power source the two poles of the earth access switch power supply U1 power input both ends
After 1 and 2 feet, under the effect of Switching Power Supply U1 internal circuit, 3 foot of power output end, 4 feet of Switching Power Supply U1 can export stable
5V DC power supply enters 1 foot of power input and 3 feet of wireless receiving circuit finished product U2, then, wireless receiving circuit finished product U2
In electric standby mode.In wireless remote control mechanism and wireless receiving mechanism: after the chamber door of box-like body is closed, power supply management
Second transmitting the key switch K2, wireless remote control mechanism U3 that personnel press portable wireless remote control mechanism U3 launch nothing
Line cut-off signal, its 4th foot can export low level, tri- pole NPN after wireless receiving circuit finished product U2 receives wireless cut-off signal
Pipe VT1 base stage is in off state without suitable bias voltage, relay J be in power loss stop working state its control power input and
Normally opened contact end disconnects, and power input and normally-closed contact end closure is controlled, due to relay J normally opened contact end and electromagnetism
The cathode power supply input terminal of door lock DC is connected by conducting wire, so this moment, electromagnetic door lock DC can power loss stop working its armature lever
It is moved right under the acting force of the spring of electromagnet, the moving armature bar right end of electromagnetic door lock DC is located in the doorframe of box-like body
Side, chamber door are in close state, and what it is due to use is not mechanical key, thus can effectively prevent stealing personnel open chamber door into
It commits theft electricity, since the cathode power supply input terminal of control circuit is connected with the normally-closed contact end of relay J by conducting wire, so this moment
Control circuit can work once electrified.In control circuit: when chamber door is closed, magnet CT and tongue tube GH distance are close, magnet CT's
Magnetic action power just acts on tongue tube GH, inside tongue tube GH movable contact and stationary contact in an ON state, tongue tube GH
After inner contact is connected, the base stage of NPN triode VT2 and emitter are shorted, the base stage of NPN triode VT2 is without suitable bias voltage
In off state, in use, the bad electricity consumption side personnel of quality attempt to open the chamber door of cabinet, and then electric energy meter
Input electric wire, output lead wherein one or two be connected in parallel, cause electric energy meter to cannot proceed normally electricity consumption meter
Amount, when opening chamber door in the case of unlawful violence, this moment, magnet CT can be spaced apart with tongue tube GH, and magnet CT magnetism is made
Do not act on tongue tube GH firmly, then, inside tongue tube GH two contacts disconnect no longer by NPN triode VT2 base stage and
Emitter is shorted, and the base stage of NPN triode VT2 obtains suitable bias voltage through resistance R2 and the output low level entrance of its collector is connected
PNP triode VT3 base stage, PNP triode VT3 conducting collector output high level enter relay J1 cathode power supply input terminal,
Then, relay J1 obtains its control power input of electric actuation and normally opened contact end closure, due to relay J1 normally opened contact end
It is connected with buzzer B cathode power supply input terminal, so this moment, buzzer B can issue loud warning sound and give electricity filching person shake
Fear, due to, buzzer B is mounted in subassembly wrapper, so, only power supply unit personnel could close the electricity of buzzer B to scene
Source (stealing personnel can not close buzzer B and administrative staff is only notified to close this moment), power supply unit administrative staff pass through existing
Buzzer B sounding, which can understand, grasps user's electricity stealing, to accomplish evidence-based accordingly to punish stealing user.Nothing
In line remote-control gear and wireless receiving mechanism: when power supply management personnel need to open the chamber door of box-like body, power supply management personnel
First transmitting key switch K1 of portable wireless remote control mechanism U3 is pressed, wireless remote control mechanism U3, which launches, wirelessly to be closed
Signal is closed, after wireless receiving circuit finished product U2 receives wireless closure signal, the 4th foot can export high level, and high level is through electricity
The base stage that the decompression of R1 current limliting enters NPN triode VT1 is hindered, NPN triode VT1 conducting collector output low level enters relay
J negative power supply input terminal, then, it controls power input and the disconnection of normally-closed contact end to relay J work once electrified, and control is electric
Source input terminal and normally opened contact termination are logical, since the cathode power supply input terminal of relay J normally opened contact end and electromagnetic door lock DC are logical
Cross conducting wire connection, so this moment, electromagnetic door lock DC can work once electrified, the armature lever of electromagnet DC under coil magnetic action power to
Left movement, the moving armature bar right end of electromagnetic door lock DC and the doorframe inner end of box-like body space out, then, administrative staff
Chamber door is pulled open forward with regard to openable chamber door.The utility model is due to wireless remote control mechanism U3, the wireless receiving electricity of wireless receiving mechanism
Road finished product U2 all has dip-switch package, and administrative staff over time, can dial wherein more of two sets of dip-switch packages
Fixed handle toggles it to corresponding position respectively, forms different new passwords, reaches better secrecy effect, can effectively prevent electricity filching person
Obtaining identical wireless remote control mechanism U3 opening chamber door by back door, (due to password difference, electricity filching person is not due to knowing nothing
Line remote-control gear U3, the password that the wireless receiving circuit finished product U2 of wireless receiving mechanism is new also can not just open chamber door.For example, handle
Handle SK1, SK3, SK4, SK6, SK8 pin of stirring of the miniature dip-switch package of wireless receiving circuit finished product U2 is stirred forward, from
And the 4 foot negative power supplies of Switching Power Supply U3 through SK1, SK3, SK4, SK6, SK8 pin enter coded integrated circuits U3-1 1,3,
4,6,8 feet (it is assumed that password figure is 13468 this moment)；Then, the miniature dip-switch package of wireless remote control mechanism U3 is stirred hand
Handle S1, S3, S4, S6, S8 pin is stirred forward, thus, the matched 12V radio transmitter reserve battery of wireless remote control mechanism U3
Negative power supply enters 1,3,4,6,8 feet of coded integrated circuits U2-1 (it is assumed that password number this moment through S1, S3, S4, S6, S8 pin
Word is 13468), then since wireless remote control mechanism U3 is consistent with the coding number inside wireless receiving circuit finished product U2, wirelessly
The wireless signal that remote-control gear U3 launches can effectively be received by wireless receiving circuit finished product U2.After a period of time, it manages
The miniature dial-up of stirring handle and wireless remote control mechanism U3 of the personnel the miniature dip-switch package of wireless receiving circuit finished product U2
Switching group stirs handle and respectively corresponds the password 24568 stirred, for example form new, even when stealing personnel illegally obtain wirelessly
Remote-control gear U3, but the miniature dip-switch package of wireless remote control mechanism U3 stir handle stir position and wireless receiving circuit at
The miniature dip-switch package of product U2 stirs handle, and to stir position inconsistent, even if so stealing personnel press wireless remote control mechanism U3
Two transmitting key switches be also unable to control wireless receiving circuit finished product U2, the confidentiality reached.The utility model can effectively prevent
The chamber door that cabinet is opened in the case of only stealing personnel non-injury is destroyed, can bring convenience to administrative staff, reduce to power supply unit
Loss, so having good application prospect.
