DETAILED DESCRIPTION

[0069] Hereafter, the specific embodiments of the present disclosure will be described in detail with reference to the accompanying drawings.

[0070] FIG. 1 illustrates a schematic diagram of a control system for controlling the start and stop of a plurality of passenger conveyors according to the present disclosure. The general idea of the present disclosure is that the control system includes a remote camera 1 and a remote controller 2 respectively provided for each passenger conveyor 3 of the plurality of passenger conveyors (only one passenger conveyor is illustrated in FIG. 1 for the sake of brevity).

[0071] The control system also includes a monitoring server 4.

[0072] The monitoring server 4 automatically issues a start instruction and a stop instruction at different predetermined times, such as but not limited to issuing a start instruction at 6:00 in the morning and a stop instruction at 23:00 in the evening.

[0073] The remote camera 1 is used for capturing images of the external state of the corresponding passenger conveyor 3 in real time.

[0074] The remote controller 2 is arranged to control and collect the operation state of the corresponding passenger conveyor 3.

[0075] The monitoring server 4 is connected with each of the remote cameras 1 and the remote controllers 2 through a data network 5. The data network 5 is, for example but not limited to, a secure local area network based on TCP/IP protocol. The remote camera 1 is, for example but not limited to, a network camera 1.

[0076] The monitoring server uses an artificial intelligence algorithm (e.g., an artificial intelligence algorithm run by an artificial intelligence computing device) to analyze the images captured by the remote camera 1 to determine whether there are passengers on the passenger conveyor 3.

[0077] When the monitoring server 4 determines that there are passengers on the corresponding passenger conveyors 3, the passenger conveyor is grouped into a non-automatic start and stop group. This means that the passenger conveyor will not be automatically started and stopped, thus protecting passengers.

[0078] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyors 3, the passenger conveyor is grouped into an automatic start and stop group.

[0079] When the passenger conveyor grouped into the non-automatic start and stop group is re-detected that there are no passengers on them, the passenger conveyor can be grouped into the automatic start and stop group.

[0080] The number of passenger conveyors in the non-automatic start and stop group and the automatic start and stop group is dynamically changed.

[0081] According to the above embodiments of the present disclosure, the control system includes a data transmission unit 6 respectively provided corresponding to each of the plurality of passenger conveyors 3.

[0082] The monitoring server 4 is connected with each data transmission unit 6 through the data network 5.

[0083] The data transmission unit 6 is arranged to receive the state data about the operation state of the corresponding passenger conveyor 3 collected by the remote controller 2 and send the state data to the monitoring server 4.

[0084] The data transmission unit 6 is also arranged to receive the automatic start and stop instruction sent by the monitoring server 4 and send the automatic start and stop instruction to the remote controller 2.

[0085] According to the above embodiments of the present disclosure, the control system further includes an alarm device 7 respectively provided corresponding to each of the plurality of passenger conveyors.

[0086] The monitoring server 4 is connected with each alarm device 7 through the data network 5.

[0089] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyor 3 grouped into the non-automatic start and stop group based on the image, the monitoring server 4 issues a start and stop instruction, and the remote controller 2 receives the start and stop instruction and controls the passenger conveyor 3 to start and stop. This also means that the passenger conveyor that did not have automatic start and stop conditions can be automatically started and stopped again.

[0090] According to the control system of the above embodiments of the present disclosure, the monitoring server 4 issues start and stop instructions to the remote controller 2 corresponding to the passenger conveyor 3 grouped into the automatic start and stop group, and the remote controller 2 receive the start and stop instructions and control the start and stop of the passenger conveyors 3.

[0136] A control method for controlling the start of a plurality of passenger conveyors according to an embodiment of the present disclosure will be described with reference to FIG. 2.

[0137] Step S1: the monitoring server 4 automatically sends a start instruction at a predetermined time.

[0138] Step S2: the monitoring server 4 uses the artificial intelligence algorithm to analyze the images captured by the remote camera 1 to determine whether there are passengers on the passenger conveyor 3 (whether on the elevator pedal and at the entrance and exit).

[0139] When the monitoring server 4 determines that there are passengers on the corresponding passenger conveyor 3, the passenger conveyor is grouped into the non-automatic start group (Step S3); the monitoring server 4 will not send a start instruction to the remote controller 2 corresponding to the passenger conveyor grouped into the non-automatic start group.

[0140] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyor 3, the passenger conveyor is grouped into the automatic start group.

[0142] After the alarm device 7 gives an alarm for a certain time (for example, but not limited to 10 seconds), the remote camera 1 continues to capture images of the external state of the passenger conveyor grouped into the automatic start group in real time.

[0143] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyor grouped into the automatic start group based on the image, the monitoring server 4 issues a start instruction, and the remote controller 2 receives the start instruction and controls the passenger conveyor to start (Step S6).

[0144] When the monitoring server 4 determines that there are passengers on the corresponding passenger conveyor grouped into the automatic start group based on the image, the passenger conveyor is grouped into the non-automatic start group (Step S5), and the monitoring server 4 will not send a start instruction to it.

[0145] Step S6: if the passenger conveyor is not started, it can be started by a manual start device (Step S7).

[0146] Step S8: after the monitoring server 4 sends the start instruction and the remote controller 2 receives the start instruction and controls the passenger conveyor to start, if the remote controller 2 determines that the passenger conveyor does not run at a slow speed and then accelerates to a normal operation speed, the passenger conveyor is grouped into the non-automatic start group (Step S9).

[0147] If the remote controller 2 determines that the passenger conveyor runs at a slow speed and then accelerates to a normal operation speed, the data transmission unit 6 is set to receive the state data collected by the remote controller 2 about the corresponding current operation state of the passenger conveyor, at this time, if the data transmission unit 6 transmits the state data to the monitoring server 4 (Step S10), the control system re-prepares the next corresponding automatic start operation (Step S1).

[0149] Step T1: the monitoring server 4 automatically issues a stop instruction at a predetermined time.

[0150] Step T2: the monitoring server 4 uses the artificial intelligence algorithm to analyze the image captured by the remote camera 1 to determine whether there are passengers on the passenger conveyor 3 (whether on the elevator pedal and at the entrance and exit).

[0151] When the monitoring server 4 determines that there are passengers on the corresponding passenger conveyor 3, the passenger conveyor is grouped into the non-automatic stop group (Step T3). The monitoring server 4 will not issue a stop instruction to the remote controller 2 corresponding to the passenger conveyor grouped into the non-automatic stop group.

[0152] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyor 3, the passenger conveyor is grouped into the automatic stop group.

[0153] Step T4: the alarm device 7 is set to give an alarm to the passengers, so as to prompt the passengers to leave the passenger conveyor or not enter the passenger conveyor within a certain time range.

[0154] After the alarm device 7 gives an alarm for a certain time (for example, but not limited to 10 seconds), the remote camera 1 continues to capture images of the external state of the passenger conveyor grouped into the automatic stop group in real time.

[0155] When the monitoring server 4 determines that there are no passengers on the corresponding passenger conveyor grouped into the automatic stop group based on the image, the monitoring server 4 issues a stop instruction, and the remote controller 2 receives the stop instruction and controls the passenger conveyors to stop (Step T6).

[0156] When the monitoring server 4 determines that there are passengers on the corresponding passenger conveyor grouped into the automatic stop group based on the image, the passenger conveyor is grouped into the non-automatic stop group (Step T5), and the monitoring server 4 will not issue a stop instruction to it.

[0157] Step T6: if the passenger conveyor is not stopped, it can be stopped by a manual stop device (Step T7).

[0158] Step T8: after the monitoring server 4 sends a stop instruction and the remote controller 2 receives the stop instruction and controls the passenger conveyor to stop, if the remote controller 2 determines that the passenger conveyor has not slowed down or stopped, the passenger conveyor is grouped into a non-automatic stop group (Step T9).

[0159] If the remote controller 2 determines that the passenger conveyor slows down or stops, the data transmission unit 6 is set to receive the state data about the corresponding current operation state of the passenger conveyor collected by the remote controller 2, and the data transmission unit 6 transmits the state data to the monitoring server 4 (step T10), and the control system re-prepares the next corresponding automatic start operation.
