Detailed ways

Now in conjunction with accompanying drawing, the utility model is described in further detail. These drawings are all simplified schematic diagrams, and only schematically illustrate the basic structure of the utility model, so they only show the configurations related to the utility model.

The utility model relates to a wireless sensing type low power consumption intelligent induction card door lock system, which comprises a sensor module, a wireless transceiver module, an access controller and an upper management computer module, and the sensor module and the access controller communicate with the upper management computer through the wireless transceiver module. For signal transmission, the sensor module is a card reader with a built-in radio frequency transmitting antenna, the access control controller is a single chip integrated with an embedded 32-bit ARM 9 single-chip microprocessor and a radio frequency transmission chip, and the wireless transceiver module is a highly integrated ZigBee-based micropower single-chip wireless transceiver, sensor module including BAP-style tags.

Each RFID-embedded access control controller adopts an integrated design of 32-bit ARM 9 embedded microprocessor, and forms a complete and reliable wireless sensor communication network (WSN) through Zigbee wireless network technology to realize real-time communication with the upper management computer. The access control controller also has the function of real-time communication with the environmental monitoring equipment. The linkage alarm parameters can be set arbitrarily through the software, arming and disarming, and real-time transmission of relevant information.

As shown in Figure 1, the system also includes electric locks, door opening buttons, alarms, door sensors and power supplies. The mechanical lock is replaced by an electric lock, and the electric lock can be opened automatically after the door opening signal is sent by the access control controller. After setting the door open button, you can press the button to open the door when you go out. The door magnetic contact detector is used to detect the switch status of the door, so as to determine whether the door opening is valid or approved, and then the access controller triggers an alarm signal. The power supply provides the operating power of the system and the power supply of the execution structure of the electric lock, and the power supply can be connected to the backup battery to ensure the normal operation of the system during a power failure. The access control controller can provide a power interruption alarm for the 12V main power supply, and send out an alarm signal through the alarm.

In the whole system, the card reader, access control controller, electric lock, door opening button, alarm and door sensor are all installed near the door and connected by wires. The card chip of the proximity card is written with a 32-bit code that never repeats. The card reader reads the proximity card information. The important channel of user information can use a fingerprint collector to collect fingerprint information through the fingerprint collector, which is more secure. The card reader has a built-in radio transmitting antenna. When a proximity card approaches, it can receive the user card information code sent by the card. After the card reader analyzes and confirms that it is a valid card, the code will be sent to the upper management through the wireless transceiver module. The computer and the wireless transceiver module receive the commands sent by the upper management computer, and then transmit the command codes to the single-chip microprocessor. After the single-chip microprocessor sends the door opening signal, the electric lock can be opened automatically.

As shown in Figure 2, ZigBee sensor networks are distributed inside hotels, guesthouses or halls. Sensor nodes use various sensors, such as radio frequency identification tags (RFID), and work with ZigBee low-power modules. The sensor nodes form a data transmission network with each other, and finally transmit all the collected data to the ZigBee nodes in each room or floor. The ZigBee nodes of each room or floor and the ZigBee central node form a network, and the data of each room or floor is uploaded to the upper management computer through this network for analysis and data storage. ZigBee has low power consumption. It consumes 1μW in sleep mode and 30mW in short-distance communication mode. In low-power standby mode, two ordinary AA dry batteries can be used for more than 6 months.

As shown in Figure 3, the main information processing program of the integrated management software is divided into two parts, which respectively complete the verification of the legality of the unlock request, and realize the query request of the user to the two databases of the user table and the login log. The interactive communication with the door lock is centrally handled by the communication program, which is used to receive the unlock request and send the verification control result.
