Abstract

The invention relates to a network type fire passage lock with the function of a cryptographic keyboard setting, which includes a microcontroller (CPU processor), a cryptographic keyboard, a signal input interface, an output interface and a mechanical lock body. The invention is characterized in that an input interface is arranged on the circuit control board; the door lock can be unlocked by inputting signal and reading card or inputting code, furthermore, the unlocking of the door lock can be set at the same time of setting alarming or not alarming and canceling the alarming by inputting code, etc. The invention is safe to use and convenient for management.

Description

A kind of network type fire fighting access lock with cipher keyboard set

Technical field

What the present invention relates to is a kind of network type fire fighting access lock with cipher keyboard set.

Technical background:

Existing fire engine access lock all is to open the door by mechanical key, cause mechanical wear to cause and can not unblank easily, and mechanical key is with carrying inconvenience.Existing fire engine access lock all is the mechanical key alarm signal that resets, and safety is not high, and the cost height is installed inconvenient.Existing fire engine access lock all is all to cross control panel inside systematic parameter is set, and secondary is provided with inconvenience.

Summary of the invention

The present invention has overcome above technical deficiency, a kind of network type fire fighting access lock warning system of brand-new band cipher keyboard set is provided, mechanical mechanism and the setting of code keypad parameter are combined, man-machine interface close friend, it is convenient that parameter is provided with simple and fast, system's all working information is all by the keyboard setting, all be kept in the inner E2PROM after setting, data are not lost after changing battery, data can be preserved more than 100 years, can cancel current warning by code keypad, whether report to the police when push rod and this device of dismounting can be set, can revise system's keyboard simultaneously and open password, when forgetting Password, the user can reinitialize password, the recovery parameter of dispatching from the factory just enters duty after system parameter setting is intact, after CPU detects danger signal, can whether effective according to the systematic parameter analytic signal automatically, CPU can send alarm signal when signal was effective, output alarm networking signal, and cooperative mechanical mechanism drives executing agency and opens fire-fighting lock simultaneously.

Description of drawings

The utility model is described in further detail below in conjunction with accompanying drawing and true example.

Fig. 1 is the machine drawing of the network type fire fighting access lock of band cipher keyboard set of the present invention

Fig. 2 is the keyboard diagrammatic sketch of the network type fire fighting access lock of band cipher keyboard set of the present invention

Fig. 3 is the circuit block diagram of the network type fire fighting access lock of band cipher keyboard set of the present invention

Fig. 4 is a program flow diagram of the present utility model.

The specific embodiment

By fire engine access lock installation drawing of the present utility model shown in Figure 1, wherein the state of Fig. 1 is the state of closing the door, and positioning box blocks dead bolt, and the outside just can not enter.Lock body 1 the inside is provided with control panel, is used to receive the push rod signal, the signal of networking signal and password figure keyboard.The 3rd, indicator lamp when pressing lower push-rod 4, drives the lock body mechanical switch, gives the control panel signal, control panel input alarm signal, red led flicker simultaneously.At this moment, we can input the password that we set in advance by numeric keypad and cancel its warning.Its detailed functions is described as follows: see Fig. 2

1, in working order down by " Setup " key, enters the state of setting behind long " a ticking " prompt tone, return duty after sending two " ticking ", " ticking " miscue sound by other key.

2, can input password after entering the state of setting, can cancel current alarm condition and voice suggestion after password is entirely true, can " warning " and " do not report to the police " state between switch by " Alarm " key this moment, when switching to " not alarm condition ", return normal operating conditions behind system sends long " ticking " sound by " alarm condition "; By " not alarm condition " when switching to " alarm condition ", system returns normal operating conditions after sending the alarm sound that long " ticking " sound sends several seconds simultaneously.

3, after the password input correctly, if the modification password must be pinned " Setup " key and not put, the quickflashing that the while green light does not stop, after waiting to hear long " ticking " change password prompt sound, the user can import new password, imports careful sign indicating number back system and sends three " ticking ", " ticking ", ticks " prompt tone, remind the user to input password second time; when having only twice password in full accord; password is revised successfully, otherwise password will be refused to revise by system, system directly returned work worker attitude after password was revised successfully.

4, can remove current input by " Clear " key when input password and modification password, can withdraw from Set For Current by " Exit ", red light dodges and sends two " ticking ", " ticking " miscue sound when input is wrong, removes current input simultaneously.

5, when the user has forgotten password, can press earlier " Setup ", hear pin simultaneously behind the prompt tone " * ",, " Clear ", " # " key, system removes current password and returns duty after hearing long " ticking " sound, remove simultaneously and report to the police, but the previous alarm condition of setting does not change, and this moment, the user can reset by above 1-4 bar.

Below enforcement of the present invention is further described in conjunction with Fig. 3 again:

1, this system adopts 4 joint 5# alkaline battery power supplies, and quiescent current is less than 25uA under non-setting, alarm condition, and system can send the alarm sound of " ticking " when battery is not enough, and red light also dodges with same frequency simultaneously, reminds the user to change battery as early as possible.

2, will test thumper, alarm and traffic lights after system powers on, and after this enter duty and can system operational parameters be set by above-mentioned keyboard operation explanation this moment.

A, when system detects the push rod signal system alarm and output networking signal.

B, when system detects danger signal system alarm, auto-unlocking and output networking signal.

C, when system detects the alarm signal that control centre sends system alarm, auto-unlocking and output networking signal.

D, when system has detected illegal this device of dismounting system alarm (just effective when system is made as alarm condition).

E, when system has detected when checking card signal, open the door automatically, after 5 seconds on the automatic locking, could remove warning after under alarm condition, having only the caretaker to input correct password.

Claims

1. what the present invention relates to is a kind of network type fire fighting access lock with cipher keyboard set, it is characterized in that: patent of the present invention mainly is by CPU, code keypad, signal input, output interface and mechanical lock body are formed, and can realize that various public passages are reported to the police and the releasing warning function.CPU detected all input signals in 24 hours incessantly, when the user promotes push rod in passage, push rod drives linkage, open fire-fighting lock, CPU detects this signal simultaneously, divide whether folding is effective alarm signal, buzzer produces warning, output networking signal in the time of effectively, and guiding the stream of people evacuate; When detecting the danger signal of sending here in control centre or other outsides, fire exit door is opened automatically, buzzer warning, the signal of output networking simultaneously; When system detected illegal this device of dismounting, buzzer sent alarm signal.After system produces and reports to the police, have only by removing warning behind 6 correct passwords of keyboard input.Can also revise user cipher by keyboard, switch alarm condition, and factory reset etc.The user also can be by swiping the card or mechanical key does not produce alarm signal from the external opening fire-fighting.
