First permanent magnet 33 of the first electromagnetic lock 3 and the second permanent magnet 43 of the second electromagnetic lock 4 all adopt suction more than the permanent magnet of 1000N, when cabinet door 82 is closed, first solenoid 32 and the second solenoid 42 be no power all, the first permanent magnet 33 of the first electromagnetic lock 3 and the first electromagnet 31 attracting; Second permanent magnet 43 of the second electromagnetic lock 4 and the second electromagnet 41 attracting, realize closing cabinet door 82, because the suction of every 1 permanent magnet is all more than 1000N, thus manpower can not open cabinet door 82.
Preferably ATMEGA88PA integrated chip is adopted in main control chip the present embodiment of controller 1.
Electron key identifier 2 is based on RFID(radio RF recognition technology) identifier.Electron key 7 is read-write rfid card.Electron key 7 is built-in with enabling authority information.Electron key 7 and electron key identifier 2 match.
Controller 1 is provided with the first current output terminal, the second current output terminal and signal input output end; Electron key identifier 2 is provided with signal input output end and radio frequency signal communication end; Power module 5 is provided with power input, the first power output end and second source output; Storage battery 6 is provided with power input and power output end; First current output terminal of controller 1 is electrically connected with the first solenoid 32 of the first electromagnetic lock 3; Second current output terminal of controller 1 is electrically connected with the second solenoid 42 of the second electromagnetic lock 4; The signal input output end of controller 1 is electrically connected with the signal input output end two-way signaling of electron key identifier 2; The power input of storage battery 6 is electrically connected with the second source output of power module 5; During use, the external AC220V civil power of power input of power module 5; First power output end of power module 5 provides working power for system, and the second source output of power module 5 is that storage battery 6 charges; During civil power dead electricity, storage battery 6 provides working power for system; Electron key 7 and electron key identifier 2 radio frequency signal communication.
The low-voltage distribution cabinet electronic lock of the present embodiment, its operation principle is summarized as follows:
When low-voltage distribution cabinet 8 be in lock a door state time, the first solenoid 32 of the first electromagnetic lock 3 and the second solenoid 42 of the second electromagnetic lock 4 be no power all; Now, the first permanent magnet 33 of the first electromagnetic lock 3 and the first electromagnet 31 attracting; Second permanent magnet 43 of the second electromagnetic lock 4 and the second electromagnet 41 attracting, realize closing cabinet door 82, because the suction of every 1 permanent magnet is all more than 1000N, thus manpower can not open cabinet door 82.
When needing to open the door, what it held by staff has the electron key 7 of enabling authority near the electron key identifier 2 be arranged on cabinet door 82, electron key identifier 2 reads the match information of this electron key 7 and sends to controller 1, after controller 1 receives enabling match information, second solenoid 42 of the first solenoid 32 and the second electromagnetic lock 4 that control the first electromagnetic lock 3 is energized simultaneously, the first electromagnet 31 of the first electromagnetic lock 3 is made to produce identical with the first permanent magnet 33 size, the magnetic force that direction is contrary, thus make the first electromagnet 31 become from the first permanent magnet 33 attracting state state of repelling each other, in like manner the second electromagnet 41 becomes from the second permanent magnet 43 attracting state state of repelling each other, now can open cabinet door 82.Controller 1 timing from namely the first solenoid 32 and the second solenoid 42 are energized, when timing was by 15 seconds, namely controller 1 cuts off the electric current of the first solenoid 32 and the second solenoid 42, and the first electromagnet 31 and the second electromagnet 41 are recovered without magnetic force state; Again at closing time, the first permanent magnet 33 of the first electromagnetic lock 3 and the first electromagnet 31 attracting; Second permanent magnet 43 of the second electromagnetic lock 4 and the second electromagnet 41 attracting, realize closing cabinet door 82.The information of each enabling all writes in electron key 7, and when needs statistics, verification, supporting supervisor only need be utilized to read the information stored in electron key 7 can be realized easily.
When low-voltage distribution cabinet electronic lock normally uses, provide working power by civil power by power module 5; And accumulators 6 charges; When civil power dead electricity, provide working power by storage battery 6 temporarily.
To sum up, the low-voltage distribution cabinet electronic lock of the present embodiment, when it uses, there is the staff of unlocking authority only with one electron key need can be beaten all power distribution cabinets in its extent of competence, avoid in prior art the trouble that staff when adopting mechanical lock finds required key in a large amount of key; Compare to mechanism lock and bolt lock, electronic key unlocking is quick, saves time simultaneously; The problems such as it adopts high strength permanent magnet iron to match with controlled electromagnet and realizes opening the door and locking a door, and its electron key is the rfid card of sealing, thus effectively can overcome mechanical lock not easily dust-proof, waterproof in prior art, easy laying dust, gets rusty and causes bite, malfunctioning; Its each unlock operation all can be recorded in electron key, is convenient to statistics when needing, verification and management.
Above embodiment is the explanation to embodiment of the present utility model; but not to restriction of the present utility model; person skilled in the relevant technique is not when departing from spirit and scope of the present utility model; can also make various conversion and change and obtain corresponding equivalent technical scheme, therefore all equivalent technical schemes all should be included into scope of patent protection of the present utility model.
