3. authority classification.According to card rights of using difference, realize fellow disciple's access rights not.
4. entrance guard management at times.Use the period difference according to door access machine, realize the different period visits of opposite house.
The drawing explanation:
Fig. 1 is the control circuit schematic diagram of gate inhibition described in the utility model, attendance recorder.
U in the accompanying drawing
oBe 80C196KC microcontroller, U
1Be ISP1016T decoding encrypted circuit, U
2Be MCM200 nucleus module, U
3Be 62256 data-carrier stores, U
4Be 27C256 program storage, U
5Be the 28C256 non-volatile data memory.Principle of work of the present utility model is that source program is assembled into machine code, with the burned program storage of code, obtains program code by decoding scheme from program storage by microcontroller with fever writes, carries out arithmetic, logical operation by the microcontroller internal circuit.When swiping the card, data deposited the non-volatile data memory preservation in microcontroller will block, and system's power down data are not lost.MAX1487E realizes communication function, finishes the exchange of gate inhibition's device and computer data.Nucleus module is realized the read-write operation to card, LCDs display text, figure.Clock chip is realized time clock feature.
The microcontroller code that at first gets instruction.Send instruction code address earlier, treat that address code is set up after, address code is added on the address bus.After send latch signal (/ALE), decoding scheme (ISP1016T) produces chip selection signal, option program storer according to input end signal.Microcontroller next send read signal (/RD), program storage output data, data enter microcontroller inside, through decoding, produce control signal.
As want access external memory, send the data address sign indicating number earlier, treat that address code is set up after, address code is added on the address bus, after send latch signal (/ALE), decoding scheme (ISP1016T) produces chip selection signal according to input end signal, selects data-carrier store, and next microcontroller send read/write signal (/RD or/WR), data-carrier store output/input data, data enter the microcontroller internal data bus, carry out arithmetic, logical operation by the microcontroller internal circuit.
As visiting exterior I/O, send the data address sign indicating number earlier, treat that address code is set up after, address code is added on the address bus.After send latch signal (/ALF), decoding scheme (ISP1016T) produces chip selection signal according to input end signal, select the I/O mouth, next microcontroller send read/write signal (/RD or/WR), the output of I/O mouth, input data, data enter the microcontroller internal data bus, carry out arithmetic, logical operation by the microcontroller internal circuit.
To blocking the read-write operation process:
The microcontroller code that at first gets instruction.Send instruction code address earlier, treat that address code is set up after, address code is added on the address bus, after send latch signal (/ALE), decoding scheme (ISP1016T) produces chip selection signal, option program storer according to input end signal.Microcontroller next send read signal (/RD), program storage output data, data enter microcontroller inside, through decoding, produce control signal.Next, send the data address sign indicating number, treat that address code is set up after, address code is added on the address bus, after send latch signal (/ALE), decoding scheme (ISP1016T) produces chip selection signal according to input end signal, selects the I/O mouth of nucleus module map.Next microcontroller send read/write signal (/RD or/WR), the output of I/O mouth, input data, and data enter the microcontroller internal data bus, carry out arithmetic, logical operation by the microcontroller internal circuit.
Report the loss, cancel report the loss, query function realizes:
Have or not card in the microcontroller inquiry antenna range, do not have card and carry out other programs.The card Card Reader is arranged, and data are sent in the microcontroller by bus in will blocking.Microcontroller reads the content of non-volatile data memory, and card number is compared with reporting the loss card number, does not open the door then for reporting the loss card as identical, and difference is then opened the door.Report the loss function, PC will be reported the loss card number by passing to gate inhibition's device under 485 communications, and gate inhibition's device deposits card number in non-volatile data memory.Function is reported the loss in cancellation, and PC will be reported the loss card number by passing to gate inhibition's device under 485 communications, and gate inhibition's device is deleted card number from non-volatile data memory.Query function, PC send querying command by passing to gate inhibition's device under 485 communications, and gate inhibition's device will all be reported the loss card number and upload.
The work attendance function realizes:
Have or not card in the microcontroller inquiry antenna range, do not have card and carry out other programs.The card Card Reader is arranged, and data are sent in the microcontroller by bus in will blocking, and microcontroller visit clock chip is obtained the current time.Card number was deposited in the non-volatile data memory together with charge time.When inquiring about work attendance, PC sends inquiry work attendance order by passing to gate inhibition's device under 485 communications, and gate inhibition's device is uploaded whole attendance records.
Authority classification is realized:
Have or not card in the microcontroller inquiry antenna range, do not have card and carry out other programs.The card Card Reader is arranged, and data are sent in the microcontroller by bus in will blocking.After the data permission section is understood in will blocking, with current gate inhibition's comparison.Allow to open the door, then door is opened, LCD screen shows " you are good, and come in " simultaneously, does not allow to open the door, and does not open the door, and LCD screen shows " your card is invalid ".
Entrance guard management function at times realizes:
Have or not card in the microcontroller inquiry antenna range, do not have card and carry out other programs.The card Card Reader is arranged, and data are sent in the microcontroller by bus in will blocking, and microcontroller compares charge time and the management data at times that writes non-volatile data memory, and charge time can be carried out following operation in effectual time.Otherwise, return.
