Abstract
The invention relates to a U flash disk door control system. The system mainly comprises a U flash disk, an information processing module and a wireless receiving module, wherein the U flash disk is used for storing user signature information, the information processing module is used for processing the signing information sent from the U flash disk and comparing and validating the signing information with the signing information preset in the program in an MCU (Microprogrammed Control Unit), the wireless receiving module is used for receiving an instruction information sent in a wireless manner, the information processing module consists of the MCU and a peripheral circuit, and the wireless receiving module consists of a GSM (Global System for Mobile Communication) wireless receiver and a serial port communication circuit. The door control system is convenient and practical, and environment-friendly and economic by replacing the traditional keys with a U flash disk, the door can be opened with a mobile phone when people forgets to carry or loses the U flash disk, so as to prevent the losing of the key and incapability of opening the door, the signing information can be modified by sending a text message instruction through the mobile phone, thereby avoiding the waste of changing a lock caused by losing of a key or changing of an owner.
Description
Technical field
The present invention relates to a kind of gate control system, particularly a kind of USB flash disk gate control system.
Background technology
Progress along with society, people are more and more higher to the quality requirements of life, most residential quarter, commercial building all can be installed the gate inhibition, what pursue is private and higher security, the access control system of much knocking on a door is at present taked is that key, magnetic card or input password opens the door, and key is easily lost, and how fragile magnetic card is, and it is also more loaded down with trivial details to input password, and the button on the gate inhibition is also fragile.The flourish USB flash disk that makes of USB flash disk industry became more and smaller and more exquisite attractive in appearance in recent years, and the increasing price of capacity is more and more lower.For USB flash disk that we are carried is more practical, save cost, designed such a USB flash disk gate control system, replace key with USB flash disk.
Summary of the invention
The object of the present invention is to provide a kind of USB flash disk gate control system, make USB flash disk not only can also open the door by access data, economize on resources, one-object-many-purposes.
For achieving the above object, the present invention realizes by the following technical solutions:
A kind of USB flash disk gate control system, comprise the USB flash disk for storage user's signature information, also the program in this signing messages and MCU is preset the message processing module that signing messages compares checking for the treatment of the signing messages that passes over from USB flash disk, be used for receiving the wireless receiving module of the command information that sends with wireless mode, described message processing module is made of MCU and peripheral circuit, and described wireless receiving module is made of gsm wireless receiver and serial communication circuit.
Further, described message processing module peripheral circuit comprises USB flash disk reading circuit, electromagnetic lock circuit and alarm circuit.
Serial communication converts the Transistor-Transistor Logic level signal to standard RS232 level by level transferring chip and communicates with level signal communication, and the level transferring chip that described serial communication circuit adopts is the MAX232 chip.
What described MCU adopted is the STC89C52 chip.
The chip that described USB flash disk reading circuit adopts is the CH375 common interface chip.
The USB flash disk read schemes:
CH375 is the common interface chip of a USB bus, supports USB-HOST host mode and USB-DEVICE/ SLAVE DeviceMode.At local side, CH375 has 8 bit data bus and reading and writing, sheet select control line and interrupt output, can be articulated to easily on the system bus of the controllers such as single-chip microcomputer/DSP/MCU/MPU.Under the USB host mode, CH375 also provides serial communication mode, is connected with single-chip microcomputer/DSP/MCU/MPU etc. by serial input, serial output and interrupt output.Can carry out reading of information to USB flash disk carry eight BDB Bi-directional Data Bus D7-D0 by eight IO mouths and CH375 on MCU by the CH375 interface chip.
USB flash disk key production program:
Gate control system adopts the method for signature verification to the checking of USB flash disk key, the user can self-defined signing messages, signing messages at 100 characters with interior and be stored under root directory in U shield.c.
Signature verification scheme:
Authorization information is implanted gate control system by the owner with short message mode by the short-message instruction preset mode, and gate control system only has when reading identical information U shield.c under the USB flash disk root directory and just can open the door.
The user can implant new signing messages again by the mobile phone instruction where necessary, perhaps opens the door.
The advantage of native system: replace key with USB flash disk, environmental protection and saving, country of side saves a large amount of iron and steel resources; Can open the door with mobile phone when leaving behind or lose USB flash disk, the key that prevents loss can not open the door, and can pass through sending short message by mobile phone modifying of order signing messages simultaneously, saves and changes the waste that lock strap is come when losing key; What USB flash disk can be done is small and exquisite attractive in appearance, with it ornament hangs over, after saving the heavy key of a large string, also elegant in appearance.
Description of drawings
Fig. 1 is the schematic diagram of USB flash disk gate control system structure of the present invention;
Fig. 2 is the system flowchart of USB flash disk gate control system of the present invention.
Embodiment
Native system mainly can be divided into three parts: USB flash disk part, information processing part, wireless receiving part are comprised of USB flash disk, USB flash disk reading circuit, single-chip microcomputer and peripheral circuit, serial communication circuit, gsm wireless receiver module etc.
Performing step of the present invention is as follows:
USB flash disk by the information read circuit that the common interface chip CH375 of USB bus forms, is searched the signing messages in U shield.c under the USB flash disk root directory automatically when inserting the gate inhibition.
MCU take STC89C52 as processor presets the signing messages contrast with program inside to signing messages by IO mouth input, is verified to export a level signal pilot relay closed electromagnetic lock circuit by the IO mouth of MCU and open the gate inhibition; If authentication failed (being the signing messages mistake) send the closed alarm circuit of level signal pilot relay by the IO mouth and report to the police.
Wireless receiving module is used for the householder by mobile phone setting/change signing messages, perhaps open the door by short-message instruction, when receiving the command information of householder's transmission, the gsm wireless receiver (is built-in with a SIM card inside wireless receiving module), MCU sends to MCU with the form of serial communication with command information by the MAX232 chip, MCU is to the checking of comparing of the form of command information and information, and decision instruction information is modified or opened the door presetting signing messages.
Communicating by letter of gsm module and STC89C52 adopts serial communication circuit to realize, but 18,19 pins of gsm module are RXD can directly carry out TTL with the RXD of single-chip microcomputer with TXD with TXD and communicate by letter unstable sometimes.So can convert the Transistor-Transistor Logic level of 18,19 pin outputs to standard RS232 level by MAX232, the RXD of while single-chip microcomputer and TXD also convert standard RS232 level to by MAX232 and communicate.
System is by above operation, realized the function of opening the door with USB flash disk, saved preferably valuable resource.
