Description
Technical field
The present invention relates to one and utilize wired Local Network or GSM/CDMA wireless access device, especially a kind of remote telephone key management cabinet.
Background technology
At present, in power system, Unattended substation becomes development trend, new management mode, brings new problem, wherein transformer substation key problem of management also life therefrom.Arbitrarily pass in and out master-control room, hyperbaric chamber, relay protection room to stop on-the-spot security personnel, rear service personnel and other irrelevant staff, many units take various way.As utilized with number envelope to manage key, removing envelope by work person in charge, and taking key, with after again sealed up for safekeeping by operations staff, this method needs often to remove spot replace band numbering envelope; Utilize strongbox keeping key, all strongbox is equipped with at each unattended substation, key is stored in strongbox, need to active station application when staff takes, staff's password is informed after agreeing to, shortcoming to tell staff's password, easily causes password to reveal, and can not play the effect of being kept absolutely secret; Gate control system is installed, installs and need a large amount of expense, and need equally to tell staff password.
Therefore, must find one under present circumstances, the manpower that need not cost a lot of money, financial resources, convenient, reliable device, effectively solves the key management problem of unattended substation again.
Summary of the invention
The object of the present invention is to provide a kind of remote telephone key management cabinet, the present invention has safe and reliable, uses rapid and convenient, convenient for installation and maintenance, cheap for manufacturing cost, widely applicable feature.
In order to reach above-mentioned purpose, solution of the present invention is:
A kind of remote telephone key management cabinet, comprises telephone control module, switch power module, 12V external power supply socket, electromagnetic lock, key switch; The both positive and negative polarity of wherein said telephone control module is connected with 12V external power supply socket respectively with after the both positive and negative polarity parallel connection of switch power module, is also in series with electromagnetic lock between described 12V external power supply socket and telephone control module; Described electromagnetic lock is in parallel with key switch; Described telephone control module is provided with telephony interface.
Between the positive pole of described telephone control module and the positive pole of switch power module, the positive pole between the negative pole of telephone control module and the negative pole of switch power module after parallel connection and negative pole are connected with the negative pole of 12V external power supply socket and positive pole respectively.
Beneficial effect of the present invention is: the present invention has safe and reliable, uses rapid and convenient, convenient for installation and maintenance, cheap for manufacturing cost, widely applicable feature.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
As shown in Figure 1, a kind of remote telephone key management cabinet of the present embodiment, comprises telephone control module 1, switch power module 2,12V external power supply socket 3, electromagnetic lock 4, key switch 5; The both positive and negative polarity of wherein said telephone control module 1 is connected with 12V external power supply socket 3 respectively with after the both positive and negative polarity parallel connection of switch power module 2; Between the positive pole of further described telephone control module 1 and the positive pole of switch power module 2, the positive pole between the negative pole of telephone control module 1 and the negative pole of switch power module 2 after parallel connection and negative pole are connected with the negative pole of 12V external power supply socket 3 and positive pole respectively.Electromagnetic lock 4 is also in series with between described 12V external power supply socket 3 and telephone control module 1; Described electromagnetic lock 4 is in parallel with key switch 5; Described telephone control module 1 is provided with telephony interface 6, direct connection telephone machine on telephony interface 6.
The circuit core element of described telephone control module 1 is the STC12C2052 single-chip microcomputer of ATMAL company, and it undertakes the work such as collection, analytic operation, output control of signal and data.Eeprom circuit is comprised in module; include house dog and voltage monitor; this circuit is combined with STC12C2052; namely the problem of not losing is kept after solving setting data power down; also solve software program and run the problem flying reset, low voltage test protected data; substantially increase the anti-interference of single-chip microcomputer, the common guarantee reliably working of circuit.When telephone control module 1 detects the bell signal from the telephone that telephony interface 6 connects, and imitate pick machine after reaching the ringing number of setting, calling party can hear that in telephone receiver in telephone control module 1, single-chip microcomputer sends three sound ring promptings.Calling party is by input password, module is verified password, password correctly sends the prompt tone be verified, password bad, sends different prompt tones, and allows calling subscribe again to input password, second time password is correct, enter program below, twice password is all incorrect, telephone control module 1 automatic hand-up.After caller correctly inputs password, just can by long-range telephone key, press numerical key to operate, control electromagnetic lock 4 live line work, chamber door, owing to being arranged on the effect of the reversed polarity strong magnets on casing, automatically springs open, exit relay automatic resetting after 2S, electromagnetic lock 4 dead bolt ejects, and prevents the long damage of electromagnetic lock 4 electrification time, and ready for closing the door.
Built-in switched power module 2 provides normal working power for whole device.Power supply is input as AC220V, provides the output of DC12V dc source through Switching Power Supply, output power of power supply 20W.
Described remote telephone key management cabinet can built-in switched power module work indicator lamp, telephone control module relay indicating light and telephone connection status indicator lamp.
When after remote telephone key management cabinet dead electricity or module failure, key locker keeps closing, and guarantees that key can not be help himself freely to; In order to chamber door can be opened in situation such as both telephone controller fault, built-in switched power fault, controller failure and built-in switched power simultaneous faults, telephone network fault etc., apparatus design DC12V external power interface 3 and need key operated key switch 5.When built-in power fault, DC12V external power interface 3 inserts external power supply, DC12V external power interface 3 is automatically by built-in switched power negative pole breaking circuit, and recovery device is powered; When telephone control module fault or telephone network fault, available key switch directly opens chamber door by key switch 5; When both simultaneous faultss, same source constantly, can utilize external power supply, and use key switch 5 to open chamber door.The present embodiment device has safe and reliable, uses rapid and convenient, convenient for installation and maintenance, cheap for manufacturing cost, widely applicable feature.
