[0029] The embodiment of the present application provides a locking system for a battery locomotive and an overhead passenger conveyor, which solves the technical problem that there is an urgent need for a system to prevent transportation accidents or even injury accidents when the battery locomotive and the overhead passenger conveyor share the same roadway and the overhead passenger conveyor starts to run when the battery locomotive is operating.

[0030] The technical solutions proposed in the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] Figure 1 This is the electrical principle block diagram of a locking system for a battery locomotive and an overhead passenger conveyor provided by an embodiment of the present application. As Figure 1 shown, a locking system for a battery locomotive and an overhead passenger conveyor provided by an embodiment of the present application specifically includes the following steps: The system includes an electronic tag, a card reader, a control host, a wireless communication base station, a weight sensor, and an emergency stop device.

[0032] The electronic tag is installed on the electric locomotive. The electronic tag includes an electronic tag antenna and an electronic tag component; the electronic tag component is connected to the electronic tag antenna; the electronic tag component outputs the data stored in the electronic tag to the electronic tag antenna.

[0033] The card reader is used to read the electronic tag. The card reader includes a reading and writing module and a card reader antenna. The reading and writing module is used to communicate with the electronic tag. The card reader is a non-contact automatic identification technology. Generally speaking, the card reader is an automatic identification device that can read passive electronic tags. It automatically identifies passive electronic tags through radio frequency signals and obtains relevant data. The identification work does not require manual intervention and can work in various harsh environments. The RFID technology can identify high-speed moving objects and can simultaneously identify multiple electronic tags, with fast and convenient operation. According to the different frequencies of reading electronic tags, it is divided into low-frequency, high-frequency, and ultra-high-frequency card readers.

[0034] The weight sensor is installed on the seat of the overhead passenger conveyor; when a staff member sits on the seat, the weight sensor detects the weight and generates a weight signal. Whether there is a staff member sitting on the seat is monitored through the weight sensor. The control host can obtain the weight signal detected by the weight sensor through the wireless communication base station. The control host can control the drive unit of the electric locomotive based on the obtained weight signal and through the wireless communication base station.

[0035] The emergency stop device is installed on the wheel disc of the overhead passenger conveyor and is used to control the operation of the wheel disc of the overhead passenger conveyor; the card reader sends a radio frequency signal of a certain frequency through the card reader antenna. When the electronic tag on the electric locomotive enters the working area of the card reader antenna, the electronic tag antenna generates sufficient induced current, the electronic tag is activated by obtaining energy, and sends out the information stored in the electronic tag component by virtue of the radio frequency energy obtained from the induced current. After the reading and writing module reads and decodes the information, it is sent to the control host.

[0036] When the control host reads the electronic tag on the electric locomotive for the first time, it indicates that the electric locomotive is about to drive into the level roadway and will occupy the level roadway. At this time, after receiving the information of the electronic tag, the control host controls the weight sensor on the overhead passenger conveyor to detect whether there is a staff member on the seat and sends the weight signal to the control host.

[0037] When there is no staff member: the control host sends an instruction to the emergency stop device through the wireless communication base station to activate the emergency stop device, and the emergency stop device controls the wheel disc of the overhead passenger conveyor to stop rotating, realizing interlock.

[0038] When there are staff members: Confirm that the overhead passenger conveyor is in working condition, and the control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to wait; when it is detected that there are no staff members and the overhead passenger conveyor is in the idle state, the control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to run, and the battery locomotive enters the level roadway.

[0039] When the battery locomotive drives away from the entrance and exit of the level roadway, the electronic tag on the battery locomotive enters the working area of the card reader antenna. The electronic tag antenna sends a radio frequency signal of a certain frequency through the card reader antenna to generate sufficient induced current. The electronic tag obtains energy and is activated, and sends out the information stored in the electronic tag component by virtue of the radio frequency energy obtained from the induced current. After the reading and writing module reads and decodes the information, it sends it to the control host.

[0040] When the control host reads the electronic tag on the battery locomotive for the second time, it indicates that the battery locomotive is about to drive away from the level roadway and no longer occupies the level roadway. At this time, after receiving the information, the control host confirms that the battery locomotive has left safely; the control host sends an instruction to the emergency stop device through the wireless communication base station to release the emergency stop device and allow the wheel disc of the overhead passenger conveyor to start rotating again.

[0041] The control host is connected to the reading and writing module, the emergency stop device, the weight sensor and the drive unit of the battery locomotive through the wireless communication base station respectively.

[0042] Install the electronic tag on the battery locomotive, and the unique car body number of the battery locomotive is stored on the electronic tag. Install the card reader at the entrance and exit of the level roadway, and the card reader communicates wirelessly with the electronic tag.

[0043] The card reader sends a radio frequency signal of a certain frequency through the card reader antenna. When the electronic tag on the battery locomotive enters the working area of the card reader antenna, the electronic tag antenna generates sufficient induced current. The electronic tag obtains energy and is activated, and sends out the information stored in the electronic tag component by virtue of the radio frequency energy obtained from the induced current. After the reading and writing module reads and decodes the information, it sends it to the control host for relevant data processing.

[0044] In the interlocking system of the battery locomotive and the overhead passenger conveyor provided by this application, the interlocking control of the battery locomotive and the overhead passenger conveyor in the level roadway is realized, ensuring that the two devices cannot run in the level roadway at the same time, realizing the reliable isolation of personnel transportation and material transportation, and ensuring the safety of personnel.

[0045] By monitoring the running state of the battery locomotive through the electronic tag and the card reader, it can automatically detect when the battery locomotive enters or leaves the level roadway, effectively preventing the risk of occupation and collision of the level roadway caused by operation errors, reducing the need for manual intervention, and reducing the safety accidents caused by human operation errors.

[0046] The contactless design of the electronic tag and the card reader makes system maintenance more convenient, reducing mechanical wear and failure rates.

[0047] Workflow: When the battery locomotive is about to enter the level roadway, the electronic tag on it enters the working range of the card reader antenna. The card reader communicates with the electronic tag through the reading and writing module and the card reader antenna to read the information in the electronic tag. After receiving the information of the electronic tag, the control host controls the weight sensor on the overhead passenger device to detect whether there is a staff member on the seat and sends a weight signal to the control host. When there is no staff member: The control host sends an instruction to the emergency stop device through the wireless communication base station to activate the emergency stop device, and the emergency stop device controls the wheel disc of the overhead passenger device to stop rotating, achieving interlock; when the battery locomotive leaves the level roadway and the electronic tag on it enters the working range of the card reader antenna again, the card reader reads the electronic tag information. After receiving the information, the control host confirms that the battery locomotive has left safely; the control host sends an instruction to the emergency stop device through the wireless communication base station to release the emergency stop device and allows the wheel disc of the overhead passenger device to start rotating again. When there is a staff member: Confirm that the overhead passenger device is in the working state, and the control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to wait; when it is detected that there is no staff member and it is confirmed that the overhead passenger device is in the idle state, the control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to run, and the battery locomotive enters the level roadway.

[0048] In an exemplary embodiment, the electronic tag is a passive electronic tag.

[0049] According to another embodiment of the present invention, the system further includes an alarm, and the alarm is connected to the control host. When the battery locomotive enters the working area of the card reader antenna, the card reader sends a radio frequency signal of a certain frequency through the card reader antenna, and the electronic tag antenna generates sufficient induced current by sending a radio frequency signal of a certain frequency through the card reader antenna. The electronic tag is activated by obtaining energy, and sends out the information stored in the electronic tag component by virtue of the radio frequency energy obtained by the induced current. After the reading and writing module reads and decodes the information, it is sent to the control host, and the control host alarms through the alarm to prompt the staff that there is a battery locomotive running in the level roadway.

[0050] According to an embodiment of the present application, the system further includes a display screen, which is connected to the control host and is used to display the presence or absence status of the battery locomotive in the level roadway. When the battery locomotive enters the working area of the card reader antenna, the card reader sends a radio frequency signal of a certain frequency through the card reader antenna. The electronic tag antenna generates sufficient induced current by sending a radio frequency signal of a certain frequency through the card reader antenna, and the electronic tag is activated by obtaining energy. By virtue of the radio frequency energy obtained from the induced current, the electronic tag sends out the information stored in the electronic tag component. After the reading and writing module reads and decodes the information, it sends it to the control host. After receiving the information of the electronic tag, the control host controls the weight sensor on the overhead passenger device to detect whether there is a staff member on the seat and sends a weight signal to the control host. When there is no staff member: the control host displays "Locomotive running, Monkey car disabled" through the display screen. When there is a staff member: the control host displays "Monkey car running, Locomotive stopped" through the display screen.

[0051] In one embodiment, the electronic tag component includes a radio frequency chip and an electronic tag data storage unit; the electronic tag antenna converts an external radio frequency signal into radio frequency energy and provides it to the radio frequency chip and the electronic tag data storage unit; the data stored in the electronic tag data storage unit is output to the electronic tag antenna.

[0052] The electronic tag antenna receives the radio frequency signal sent by the card reader and obtains radio frequency energy by virtue of the induced current. The radio frequency chip outputs the chip select and clock signals for reading the electronic tag data storage unit and outputs the tag data through the electronic tag antenna. After the electronic tag enters the magnetic field, it receives the radio frequency signal sent by the card reader and sends out the information stored in the electronic tag data storage unit by virtue of the radio frequency energy obtained from the induced current. After the reading and writing module reads and decodes the information, it sends it to the control host for relevant data processing.

[0053] As an example, the operating frequency band of the radio frequency chip is 860 MHz to 915 MHz.

[0054] It should be further noted that the card reader further includes a rechargeable battery and a power management circuit; the rechargeable battery supplies power to the card reader through the power management circuit; the power management circuit is also used for charging management of the rechargeable battery.

[0055] As an example, the emergency stop device is a locking brake device.

[0056] The following are embodiments of the interlocking method for a battery locomotive and an overhead passenger device provided by the present disclosure. The interlocking method for the battery locomotive and the overhead passenger device belongs to the same inventive concept as the interlocking system for the battery locomotive and the overhead passenger device in the above embodiments. Details not described in detail in the embodiments of the interlocking method for the battery locomotive and the overhead passenger device may refer to the embodiments of the interlocking system for the battery locomotive and the overhead passenger device above.

[0057] Combined with Figure 2 , a method for interlocking a battery locomotive and an overhead passenger device provided by the present invention, the method includes: Read an electronic tag installed on the battery locomotive through a card reader to determine whether the battery locomotive is about to occupy the level roadway; Detect the passenger state of the overhead passenger device through a weight sensor, and then determine whether the overhead passenger device is in a working state; According to the information of the read electronic tag and the signal of the weight sensor, determine the safety state in the level roadway to prevent the battery locomotive and the overhead passenger device from running simultaneously.

[0058] In one embodiment, the method specifically includes: When the battery locomotive is about to enter the level roadway, the electronic tag on it enters the working range of the card reader antenna.

[0059] The card reader communicates with the electronic tag through a reading and writing module and the card reader antenna to read the information in the electronic tag.

[0060] After receiving the information of the electronic tag, the control host controls the weight sensor on the overhead passenger device to detect whether there is a staff member on the seat, and sends a weight signal to the control host.

[0061] When there is no staff member: The control host sends an instruction to the emergency stop device through the wireless communication base station to activate the emergency stop device, and the emergency stop device controls the wheel of the overhead passenger device to stop rotating to achieve interlocking.

[0062] When the battery locomotive leaves the level roadway and the electronic tag on it enters the working range of the card reader antenna again, the card reader reads the electronic tag information. After the control host receives the information, it confirms that the battery locomotive has left safely.

[0063] The control host sends an instruction to the emergency stop device through the wireless communication base station to release the emergency stop device and allow the wheel of the overhead passenger device to start rotating again.

[0064] When there is a staff member: Confirm that the overhead passenger conveyor is in working condition. The control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to wait. When it is detected that there are no staff members and it is confirmed that the overhead passenger conveyor is in an idle state, the control host sends a control signal to the drive unit of the battery locomotive to control the battery locomotive to run, and the battery locomotive enters the level roadway.

[0065] The control host continuously monitors the signals of the electronic tags and the weight sensors to ensure the safety status throughout the level roadway. By judging whether the overhead passenger conveyor is in an occupied state through the signal of the weight sensor, it is ensured that the battery locomotive can only start when the overhead passenger conveyor is unoccupied, thus avoiding the risk of the overhead passenger conveyor and the battery locomotive running simultaneously.

[0066] This interlock mechanism ensures that the overhead passenger conveyor and the battery locomotive do not run simultaneously in the level roadway, improving the safety of operation in the level roadway.
