Description

Technical Field

[0001] This utility model relates to the field of elevators, specifically a dynamic shielding system for elevator service floors. Background Technology

[0002] With the rapid development of elevator technology, the demand for dynamic management and control of elevator services in various scenarios is becoming increasingly prominent. Traditional elevators typically preset service floors via software during installation and commissioning. Later, when a floor is deactivated, professionals need to use specialized equipment to connect to the mainboard and modify parameters. The technical bottlenecks are concentrated in the following aspects: Architectural limitations: Traditional systems rely on pure software configuration and lack a hardware-level physical signal triggering mechanism, resulting in floor status adjustments not being directly linked to the elevator's real-time control system; Lack of dynamic response: Existing solutions require elevator shutdown and connection to commissioning equipment to modify parameters, failing to achieve dynamic updates of floor strategies during elevator operation, severely impacting building operation efficiency; High dependence on maintenance: Floor blocking operations must be performed through specialized interface equipment and rely on on-site technical personnel, with an average response cycle of 1-3 hours, making it difficult to meet emergency management needs; Insufficient emergency response capabilities: In typical scenarios such as pollution isolation and control in medical institutions, peak passenger flow management in shopping malls, and freight elevators in logistics centers, existing systems lack rapid hardware blocking mechanisms, posing safety hazards and management lag risks.

[0003] The shortcomings of existing elevators are particularly prominent in the process of intelligent transformation of high-rise buildings, exposing the systemic deficiencies of traditional elevator control systems in terms of real-time performance, autonomy, and safety. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] This invention provides a dynamic shielding control system and device for service floors. By integrating a physical switch module into the car control panel, a hardware-level trigger control channel for service floors is constructed. This enables rapid shielding and restoration of service floors.

[0025] Please see Figure 1-2 An elevator service floor dynamic shielding system includes an elevator control main board, a car control board, a car expansion board, and a service floor switch group; the elevator control main board and the car control board are communicatively connected, the car control board and the car expansion board are communicatively connected, and the car expansion board and the service floor switch group are communicatively connected; the service floor switch group consists of multiple independent physical switches, each independent physical switch corresponding to a specific floor;

[0026] The elevator control main board model is KLA-MCU-201*; the car control board model is KLL-CCU-401*; the car expansion board model is KLL-TAN-411*; and the service floor switch group is SNS.

[0027] The JP1 interface of the car expansion board is connected to the JP7 interface of the car control board via a ribbon cable.

[0028] The communication lines TXV+, TXV-, TXA+, and TXA- of the JP2 plug-in on the car control board are connected to the TXV+, TXV-, TXA+, and TXA- interfaces in the JP1 plug-in on the elevator control main board via traveling cables.

[0029] When the physical switch for the service floor is normally open, the corresponding indicator light on the car extension panel for the service floor will be off.

[0030] The service floor interface of the car extension plate is electrically connected to the independent physical switch of the corresponding floor in the service floor switch group.

[0031] The service floor switch group is integrated and installed on the control panel of the control box.

[0032] The COM port on the car expansion board is connected to the COM port in the service floor switch group.

[0033] The power port on the car expansion board is connected to a +24V power supply.

[0034] The control panel is also equipped with an automatic / driver switch, a normal / independent switch, a normal / stop switch, a lighting switch, a fan switch, a backup switch, and down, up, and direct buttons.

[0035] Figure 3 As shown, when the floor service shielding switch in the car control box is triggered, the car expansion board detects the corresponding indicator light activation low-level signal through the opto-isolated input circuit, and then sends a floor shielding command to the elevator control main board through the CAN bus communication protocol. After receiving the command, the main board shields the corresponding service floor, defines it as a non-service floor and does not stop, the elevator's external call and in-car registration command functions are disabled, and the registered commands are cancelled.

[0036] Figure 4 As shown, when the elevator is in operation, if the shielding switch is triggered while it is heading to the target floor, the operating logic is as follows:

[0037] a) Figure 5 As shown, when the elevator is in the acceleration or constant speed operation phase, if the shielding switch is triggered while it is heading to the target floor, both the external call and in-car registration functions are disabled, and the registered commands are cancelled. The optimal path is then replanned. If there is a registered command in the same direction, the elevator continues to run in the same direction to the nearest next floor to be served. If there is no command in the same direction, the nearest stopping strategy is activated, and the elevator decelerates and stops at the nearest permitted stopping floor at the current location, executing the normal door opening and closing procedure.

[0038] b) Figure 5As shown, when the elevator is in the deceleration phase, if the shielding switch of the target floor it is about to stop at is triggered, both the external call and in-car registration functions become invalid, and the registered commands are cancelled. The elevator follows the safe stopping principle, maintaining the current deceleration curve to continue running to the target floor. After stopping, the car door remains closed, and the route is replanned. If there is a pending service command, the elevator will proceed to the most recently registered command and execute the normal door opening and closing procedure. If there is no pending service command, the elevator will proceed to the adjacent service floor and execute the normal door opening and closing procedure.

[0039] This invention provides a dynamic shielding control system and device for service floors. By integrating a physical switch module into the car control panel, a hardware-level trigger control channel for service floors is constructed. This enables rapid shielding and restoration of service floors.

[0040] This invention innovatively employs a hardware-level physical switch triggering mechanism to construct a real-time dynamic shielding management system for elevator service floors. Compared to traditional solutions, it offers advantages such as simple operation, rapid response, and high reliability. It is particularly suitable for scenarios such as temporary visitor access control in smart buildings, elevator isolation in contaminated areas of medical buildings, and dynamic capacity allocation in transportation hubs. Through reliable hardware-level control, it significantly improves building management efficiency and elevator operation safety.
