[0019] The detection module is responsible for real-time monitoring of the touchscreen's operating status parameters, including touch response signals, display refresh signals, and internal processor operating status. This module uses sensors and data acquisition circuits to transmit the collected parameters to the central control module for analysis and processing.

[0020] The central control module is the core of the entire emergency control system. It receives parameters from the detection module, determines whether the touchscreen has crashed, and if a crash is detected, sends a switching command to the switching control module and simultaneously activates the emergency procedure module. After the touchscreen is repaired, it controls the self-test and recovery process.

[0021] Switching Control Module: Based on instructions from the central control module, this module switches the elevator's control signal transmission channel from the touchscreen to a backup control module, such as a button control unit or a remote control receiving unit. This module includes signal switching circuitry and communication interface circuitry to ensure stable transmission of control signals.

[0022] Emergency Procedure Module: Upon receiving the activation command from the central control module, it executes a series of emergency operations. This includes a communication unit that sends alarm information to the elevator management center, a control unit that controls the emergency lighting module and ventilation system, and a voice broadcast unit that plays reassuring messages.

[0023] Backup control module: Composed of a button control unit and a remote control receiving unit. It can be a physical button control unit, receiving button presses from passengers and transmitting commands to the elevator control system. Alternatively, it can be a remote control receiving unit, connected to a remote control center via a communication network, receiving remote control commands and transmitting them to the elevator control system.

[0024] Specifically, the backup control module includes a button control unit and a remote control receiving unit. Both the button control unit and the remote control receiving unit are electrically connected to the elevator control system. The backup control module receives the button operations of passengers and transmits the instructions to the elevator control system. Alternatively, it can be a remote control receiving unit that connects to the remote control center through a communication network, receives remote control instructions, and transmits them to the elevator control system.

[0025] Specifically, the emergency procedure module includes a communication unit, a control unit, and a voice broadcasting unit. The communication unit is electrically connected to the elevator management center, the control unit is electrically connected to the emergency lighting module and the ventilation system, and the voice broadcasting unit is electrically connected to a voice playback device. The communication unit sends alarm information to the elevator management center, the control unit controls the emergency lighting module and the ventilation system to turn on or off, and the voice broadcasting unit plays reassuring voice messages through the voice playback device.

[0026] Specifically, the detection module includes a sensor and a data acquisition circuit. The sensor is electrically connected to the central control module through a data acquisition electrical connection.

[0029] The emergency control method of this system is:

[0030] 1. System Freeze Detection: The system continuously monitors the touchscreen's operating status, determining whether it has frozen by detecting multiple parameters such as the touchscreen's touch response signal, display refresh signal, and the internal processor's operating status. For example, if no touch response signal is detected within a preset time, the display screen remains unchanged, and the internal processor's operating frequency is below the normal threshold, the touchscreen is determined to be frozen.

[0031] 2. Switching to Backup Control: Upon detecting a touchscreen malfunction, the system immediately switches to the backup control module via automatic switching. The backup control module can be a physical button control located inside the elevator car, or it can be temporarily controlled via a remote control center. When switching to physical button control, the system activates the physical button circuit, switching the control command transmission channel from the touchscreen to the physical buttons. If remote control center takeover is used, the system transmits the elevator's real-time status information to the remote control center via a communication network, allowing remote operators to control the elevator through the remote control platform.

[0032] 3. Activate Emergency Procedures: Upon switching to standby control, the system activates the emergency procedure module. This module includes sending alarm information to the elevator management center, informing them of the touchscreen malfunction and providing detailed information such as the elevator's location and operating status.

[0033] 4. Recovery and Restart: After the elevator management personnel arrive on site, they will troubleshoot and repair the touchscreen. After repair, the system will first perform a self-check to ensure the touchscreen and related control circuits are back to normal operation. Then, the control module will be switched back to touchscreen control from the backup control module, and the elevator will be test-run. Once all elevator functions are confirmed to be normal, normal operation will resume.
