Embodiment
The present invention is described in detail below in conjunction with drawings and Examples.
A kind of safety door inhibition control device based on FPGA of the present invention comprises: electric control system, magnetic key operated lock 4; During magnetic key operated lock 4 energising, door closes, and during magnetic key operated lock 4 outage, door is opened.
Described electric control system further comprises: by microcontroller 6, status indicator lamp 7, internal switch 1, button Acquisition Circuit 2, the magnetic key operated lock control circuit 5 of FPGA cutting; Microcontroller 6 is comprised of the MCU of FPGA cutting, comprises button service module, password storage unit, interrupt management module, magnetic key operated lock control module and wireless module 3; Wherein, the button service module is by 0 ~ 9, acknowledgement key 2E of ten password input keys, cancel key 2Q and three and door, first with a door U1, second with door U2, the 3rd with door U3 composition; Described magnetic key operated lock control circuit 5 comprises a resistance, triode 5A, and resistance one end connects power supply, the collector of an end connecting triode 5A, and magnetic key operated lock 4 is connected with the emitter of triode 5A.
The button service module is connected with the input end of button Acquisition Circuit 2, and the magnetic key operated lock control module is connected with the input end of magnetic key operated lock control circuit 5, and the button Acquisition Circuit is connected output terminal and is connected with the common input end of microcontroller 6 respectively with the magnetic key operated lock control circuit; Status indicator lamp 7 is connected with the common circuit of output terminal of microprocessor 6; Input/output function by changing common input/output end port and the high-low level of output, the flickering of state of a control pilot lamp 7, the break-make of triode 5A and the detection of button.Internal switch 1 is connected with the interrupt management module input circuit of microcontroller 6 with the 3rd port 8 of door U3 with the 3rd, when button is pressed, can trigger interruption, and processor is finished corresponding processing.
Microcontroller 6 carries out the password coupling by the scanning key-press input, and the correct magnetic key operated lock outage of Password Input sends information by wireless module 3 to information desk simultaneously, guarantees security.If the Password Input mistake, the state of magnetic key operated lock 4 is constant, if continuous three failures, the scanning that then stops key does not allow user's again Password Input, and passes through wireless module 3 to information desk transmission information, in order to guarantee safety.Provide simultaneously a switch, in order to open internally magnetic key operated lock 4.The present invention can receive the wireless messages that information desk sends, the operations such as change state and password.
See figures.1.and.2, the present embodiment supposing the system uses for the first time, and password is password default 011110.
After system starts, at first enter monitor state 101, this moment, status indicator lamp 7 was bright, and magnetic key operated lock 4 is in closed condition.Press password input key 0, enter key scan state 102, the scanning button, the record key value is returned and is entered monitor state 101.Push button continuously 1,1,1,1,0, then press acknowledgement key, enter password matching status 104, Password Input is correct.Enter magnetic key operated lock 4 open modes 103, magnetic key operated lock 4 is opened, status indicator lamp 7 flicker 3s, and magnetic key operated lock 4 meeting autoshutdowns after the 3s, status indicator lamp 7 recovers to continue bright state.When magnetic key operated lock 4 is opened, enter wireless communication state 105, send to the foreground by the wireless message that magnetic key operated lock 4 is opened, finish the supervision to room door.If this room is not hired out, then give the alarm, point out illegal entering, guarantee the safety in room.If Password Input mistake and the frequency of failure are less than 3, magnetic key operated lock 4 can not be opened, and enters to empty input password state 106, and input is emptied, and the user can re-enter; If continuous 3 times are inputted unsuccessfully, the scanning of the input that then can stop key does not allow user's again input, and enters wireless communication state 105, by wireless warning information is sent to the foreground, guarantees the safety in room.If the user presses cancel key in the process of Password Input, enter and empty password state 106, the password of input can re-enter before emptying.
After the Password Input success, the user enters within the room, when wanting to withdraw from a room, presses internal switch, and enter magnetic key operated lock 4 open modes 103 this moment, and magnetic key operated lock 4 is opened, and can withdraw from a room, and magnetic key operated lock 4 can autoshutdown after the 3s.
When wireless module 3 is received the wireless signal of sending on the foreground, pass to microcontroller 6, microcontroller 6 is resolved, if the instruction of change password, corresponding 107 states at first carry out the password coupling, if the original password that provides and password storage element is identical, then changing current password is new password, and replys the change successful information; If the original password that provides is different from the password storage unit, does not then change, and reply failure information; If be unrecognizable instruction, then abandon.
When the Password Input frequency of failure surpasses 3 times, this moment, system can not carry out the scanning of button again, want to recover this function, can only press internal switch 1 by foreground wireless transmission instruction or in house interior, with frequency of failure zero clearing, then recover the key scan function, respectively corresponding 107 and 103 states.
Above content is the further description of the present invention being done in conjunction with optimal technical scheme, can not assert that the implementation of invention only limits to these explanations.Concerning the general technical staff of the technical field of the invention, under the prerequisite that does not break away from design of the present invention, can also make simple deduction and replacement, all should be considered as protection scope of the present invention.
