Based on the configured drive unit, sensor unit and platform controller, each track span can independently perform opening and closing control and realize the measurement of sensor signals required during the operation process;

[0047] In this solution, for a track, the track controller and all drive units and sensor units configured in the track are connected through a bus. Based on the bus, the track controller can realize the opening and closing control of any track span in the track;

[0048] In this solution, the system controller 100 is connected to each track controller in communication, so the opening and closing control of any track span in each track can be achieved based on the system controller 100.

[0106] Exemplarily, in this solution, the track controller and the sub-control cabinet can be configured on the second-floor platform to facilitate the staff to perform opening and closing operations of the corresponding track spans. In addition, guardrails can also be configured on the second-floor platform to provide protection for personnel when they are working or not working.

[0108] In this solution, the system controller 100 is a computer, the track controller is a PLC, and the system controller is connected to the switch 200 (TCP) via a TCP network cable;

[0109] For a track, the track controller, IO module and motor driver of the track are connected via the EtherCAT field bus using a linear topology.

[0110] In this scheme, the openable and closed working platform is used for the separation and assembly of the bogies of the sky-high rail electric passenger car, and the inspection and maintenance of the roof part;

[0111] Its supporting control system mainly consists of a main control cabinet (system controller), two track controllers, and 12 sub-control cabinets (including two intermediate cabinets);

[0113] The track controller can be configured to collect sensor measurement information sent to its engine via the EtherCAT bus in real time and display it on the operation screen. When the sensor measurement information is abnormal, the three-color indicator light is controlled to emit light in the specified color.

[0114] The system controller used for overall control can be configured as follows: only when the authorization indicator on the system controller is on (i.e., the designated track controller is authorized to allow operation), the button operation on the track controller is effective;

[0115] Track controller and three-color indicator light can be used to realize: signal indication that a single-span track span is in operation, indication of track span line opening (i.e. track beam closure) after operation, and alarm indication of each step working status and abnormal status (e.g. latch not moving into place, etc.);

[0116] The system controller or track controller can be configured with the following functions: power-on self-test, automatic control of track beam opening and closing, operation status display, human-computer interaction, warnings and alarms, and signal processing.

[0117] In this scheme, the mechanical movement of the working platform is the opening and closing of the track beam, and the loosening and locking of the (track beam positioning) latch;

[0118] The opening and closing of the track beam of each track span is realized by a private servo motor through synchronous motion control. The opening and closing states are connected to the track controller by the limit switch signal. The track controller is configured to realize the logical judgment of opening and closing.

[0119] The latches of a track span are divided into four left and right parts, which are driven up and down by four electric cylinders to realize the release and locking of the latches. The release and locking status are connected to the track controller by the limit switch signal to realize the logical judgment of release and locking in place.

The system controller is connected to the track controller via a TCP network cable, and information exchange and the issuance of control instructions are realized through the TCP network cable.

[0122] The operation mode of the work platform can be switched through the system controller. When the remote operation mode is in effect, the corresponding track can be selected through the operation interface of the system controller. When there is no vehicle on the track, the 6 track sections in each track can be opened and closed at the same time, and all the latches of the same track can be released and locked at the same time.

[0123] When switching to the local operation mode, the operator can use the corresponding position operation box on the second-floor platform to open and close the span of the track section, and to loosen and lock the latch of the section;

[0124] The operating box can realize the simultaneous or separate opening and closing of the two track beams across the section of track by selecting the knob, and can also realize the simultaneous or separate loosening and locking of the latches of the two track beams.

[0126] Self-test / status check: including the open and closed status detection of the track beam and the latch status detection of each track span. When the machine is powered on for self-test, the three-color indicator light will display red light (open state) or green light (closed state) according to the self-test signal;

[0127] According to the inspection or self-inspection results, remote operation (system controller or track controller) or local operation (operation box) is used to control the corresponding components to reach the specified working state;

[0128] Prompt that the vehicle can enter: Based on the information displayed on the sensor status, the interface (on the integrated billboard or operation screen) specifically displays whether there is a vehicle and the vehicle's driving position.

[0129] Vehicle entry: Displays the vehicle entry and parking position, and displays the track beam load status based on real-time feedback from the (gravity) sensor (displays red and green data depending on whether the load threshold is exceeded);

[0130] Overhead crane hoisting (manual operation): During the inspection, the hoisting equipment hoists the bogie to release the load applied by the bogie on the track beam; the hoisting equipment lifts the bogie and moves it out of the inspection platform, and then hoists a new bogie without fault to the electric passenger car to be inspected;

[0131] Remote / local latch authority: latch operation is divided into two modes. In remote mode, the latch of each track span is controlled by the system controller, and the in-place status is monitored in real time. In local mode, the latch of each track span is controlled by the system operation box, and the in-place status of the latch is monitored by the track controller.

[0132] Remote / local opening and closing authority: Track beam opening and closing operations are divided into two modes. In remote mode, the servo motor of each track span is controlled by the system controller, and the in-place status is monitored in real time. In local mode, the servo motor of each track span is controlled by the system operation box, and the in-place status of the track beam is monitored by the track controller.

[0133] Guardrail (manual opening): Configure the track controller to check the guardrail opening signal status, and display the guardrail opening and closing status of the corresponding track span on the operation screen of the track controller;

[0134] The overhead crane is hoisted into the bogie: After the system controller or track controller is configured to check that the track beam is fully opened, the latch is fully opened, and the guardrail is fully opened, the indicator light of the corresponding track span is controlled to turn on red, and the two-color signal light outside the warehouse gate turns on red;

[0135] Operation completed: configure the system controller or track controller to check that the track beam is closed in place, the latch is closed in place, and the guardrail is not opened in place, then control the indicator light of the corresponding track span to show green light, and the two-color signal light outside the warehouse gate to show green light when leaving the warehouse.
