Each railway access door is provided with an electronic lock 150 and a network camera 170, a plurality of base stations 130 are communicatively connected with the monitoring platform 110, and each base station 130 is correspondingly communicatively connected with a plurality of electronic locks 150 and a network camera 170. The base station 130 is used to establish communication between the electronic lock 150, the network camera 170 and the monitoring platform 110.
[0034] The base station 130 is used to transmit the data sent by the electronic lock 150 to the monitoring platform 110, or send the control instructions sent by the monitoring platform 110 to the electronic lock 150, and the electronic lock 150 is set in the monitoring platform 110. The access door, the electronic lock 150 is used to control the opening or closing of the access door under the control instruction of the monitoring platform 110, and the base station 130 is used to detect the opening and closing of the electronic lock 150 according to a preset time interval Status, and send the detected opening and closing status of the electronic lock 150 to the monitoring platform 110, the monitoring platform 110 is used to control the opening or closing of the electronic lock 150, and store the opening and closing status of the electronic lock 150 .
[0035] The electronic lock 150 is used to control the opening or closing of the access door. Preferably, the electronic lock 150 can read the user's identity information, and determine whether to open the access door according to the read identity information, or open or close the access door under the remote control of the monitoring platform 110. See figure 2 , The electronic lock 150 includes a main control unit 151, an electromagnetic driver 153, an RFID reading unit 155, a magnetic sensor unit 157, and a communication unit 159. The electromagnetic driver 153, the communication unit 159, the RFID reading unit 155, and the magnetic sensor unit are all electrically connected to the main control unit 151.
[0036] The communication unit 159 is configured to send data to the monitoring platform 110 or receive control instructions sent by the monitoring platform 110 under the control of the main control unit 151. For example, the communication unit 159 may send the identity information read by the RFID reading unit 155, or receive a control instruction sent by the monitoring platform 110, and the control instruction includes opening or closing an access door.
[0037] Preferably, the communication unit 159 selects an RS-485 transceiver. The RS-485 transceiver uses a differential signaling mechanism to realize data transmission in long-distance and noisy industrial environments, suppress common mode noise, and achieve better data transmission effects.
[0038] The electromagnetic driver 153 is used for controlling the opening or closing of the lock bolt under the control of the main control unit 151 according to the control instruction. The electromagnetic driver 153 is a mechanical device controlled by a relay. The relay is electrically connected to the main control unit 151. The relay is used to control the working state of the rotating link, and the rotating link is connected to the lock bolt for controlling the opening or closing of the lock bolt. shut down. When the relay is powered on, the electromagnet is driven to open the rotating connecting rod, and the lock bolt is released to unlock. When the relay is de-energized, the rotating connecting rod will fall, and the lock bolt will lock and close the lock.
[0039] The RFID reading unit 155 is used to identify the electronic label data of the device, and send the identified electronic label data to the main control unit 151. The main control unit 151 controls the electromagnetic driver 153 to turn on or off the electromagnetic driver 153 according to the identified electronic label data. Lock bolt, the main control unit 151 also sends the identified electronic tag data to the monitoring platform 110 through the communication unit 159. For example, the RFID reading unit 155 is used to identify the electronic tag of the device held by the user or staff. The electronic tag of the device can be a "all-in-one card". When the tag approaches, it receives the radio frequency signal sent by the reader and obtains the result by the induced current. The energy sends out the identity information stored in the chip. After the RFID reading unit 155 reads the identity information and decodes the information, it is transmitted to the main control unit 151 for relevant data processing. For example, the main control unit 151 compares the read identity information with the legal identity information sent by the monitoring platform 110, and if there is a match, it controls the electromagnetic driver 153 to open the lock bolt, and at the same time sends the read identity information, door opening time, etc. To the monitoring platform 110. If it does not match, record the abnormal information, and send the abnormal information to the monitoring platform 110.
[0040] The magnetic sensor unit 157 is used to detect the open and close state of the lock bolt, and send the detected open and close state to the main control unit 151, and the main control unit 151 passes the detected open and closed state through the communication unit 159 The base station 130 sends to the monitoring platform 110. Preferably, the magnetic sensor unit 157 can detect state changes such as the locked position of the lock bolt and the closed position of the door through a magnetic induction method, and convert them into electrical signals, which are sent to the main control unit 151. In this embodiment, the opening and closing states detected by the magnetic sensor unit 157 include four types: door unlocked open, door unlocked closed, door closed locked, and door closed locked open.
