Technical Field

[0001] This utility model relates to the field of elevator technology, specifically a control device that uses a call box button to realize the elevator stop switch function. Background Technology

[0002] The elevator lobby stop / lock switch (hereinafter referred to as the stop switch) is a core device for elevator safety management and is currently generally in the form of a mechanical key switch. This device is usually installed on the surface of the elevator lobby call box (with "stop" and "lock" signs around the switch), and uses a physical key to control the opening and closing of the elevator.

[0003] However, since physical keys require dedicated personnel to keep and distribute them, and maintenance personnel must carry them with them at all times, there are risks of key loss and duplication, as well as inconvenience in carrying them. Moreover, in emergencies or temporary operations, time is required to search for keys, thus delaying the golden rescue time and affecting the efficiency of elevator maintenance and rescue. Utility Model Content

[0018] Figure 3 This is a schematic diagram of the wireless communication module circuit of this utility model. Detailed Implementation

[0019] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a control device that uses a call box button to realize the elevator stop switch function, including an external call communication board for connecting to the call box button. The call box button includes an up button and a down button, but does not have a stop button. One end of the external call communication board is connected to the elevator main board. The external call communication board includes a main control unit for sending the stop signal and stop method to the elevator main board, and a signal acquisition module for real-time monitoring of the call box button signal. The signal acquisition module is electrically connected to the main control unit.

[0021] By combining the main control unit and signal acquisition unit with the call box buttons, this device eliminates the need to modify the appearance of the call box (no additional buttons or identification areas are required). While maintaining existing operating habits, it utilizes the existing up and down buttons to achieve the elevator stop / start function, completely eliminating physical keys. Furthermore, it can authorize different management personnel through different combinations. When performing elevator stop or operation, the control system can record relevant information. In addition to stopping the elevator, it can also perform maintenance and repair functions. Compared with existing technologies, it has significant technological advancements and practicality.

[0022] The main control unit includes a main CPU, which is connected to the up button and the down button respectively. The main CPU sends the stop signal and the stop method to the elevator mainboard to complete the stop action and generate a stop log. The elevator mainboard is the core component of the elevator control system. It is responsible for receiving, processing and outputting control signals, coordinating the operation of various elevator components, and ensuring the safe, stable and efficient operation of the elevator. This utility model does not improve the elevator mainboard, so it will not be described in detail here.

[0023] The signal acquisition unit includes a slave CPU, which is connected to the main CPU, the up button, and the down button. The slave CPU monitors the pressing status and pressing duration of the up and down buttons on the call box in real time. The signal of the up and down buttons is continuously monitored, such as when they are pressed or released. When an operation sequence that meets the preset elevator stop trigger conditions is detected, it is determined to be a valid elevator stop request, and an elevator stop signal and elevator stop method are sent to the control module of the elevator control system.

[0024] Both the slave CPU and the main CPU include the MKE06Z64 chip. The MKE06Z64 chip is equipped with a connection interface for connecting to the up and down buttons. The MKE06Z64 chip is based on the ARM Cortex-M0+ core, with a maximum operating frequency of 48MHz. It has a single-cycle 32-bit multiplier and a single-cycle I / O access port, which can quickly process complex control algorithms and instructions. The chip has multiple low-power modes, such as running mode, waiting mode, and stop mode, which can automatically adjust power consumption according to the elevator's operating status to reduce system energy consumption.

[0025] Both the elevator mainboard and the external call communication board are equipped with RS485 interfaces. The two RS485 interfaces are connected by a communication cable. The RS485 interface adopts differential signal transmission, which can effectively suppress common-mode interference and keep the signal stable during long-distance transmission. In the elevator system, the elevator mainboard and the external call communication board may be located in different positions and far apart. The RS485 interface can support communication distances of up to 1200 meters or even longer, meeting the communication needs between various components of the elevator system.

[0026] The CPU is connected to a wireless communication module for wireless communication. The wireless communication module is integrated on the external call communication board. Through the cooperation of the wireless communication module and the signal acquisition module, remote wireless control of elevator shutdown operation can be realized, thereby improving the efficiency of elevator maintenance and rescue.

[0027] The wireless communication module includes a WiFi module, which integrates an ESP8266 chip U11. Pin 8 of the ESP8266 chip U11 is connected to a capacitor C44 to ground, and the connection between pin 8 of the ESP8266 chip U11 and the capacitor C44 is connected to a 3.3V voltage. Pins 9 and 17 of the ESP8266 chip U11 are both grounded. The ESP8266 chip U11 enables the control device to connect to an existing WiFi network, realizing wireless communication functionality. This eliminates the constraints of wired connections, increasing the flexibility and portability of the device. Through the Internet, users can remotely control devices connected to the WiFi module or monitor the device's status in real time from any location with network access, improving the convenience of remote control.

[0028] When using, such as Figure 2As shown, the call box button first waits for a button press event. If there is no button action, it continues to wait. If there is a control action, the CPU detects the action duration. If the action duration does not meet the trigger duration, the call is registered and normal operation resumes. When the elevator reaches the designated floor, it continues to wait for a button press event. If the action duration meets the trigger duration, there are two scenarios: one is that when the elevator is in normal operation, the main CPU receives the trigger request, triggers the elevator mainboard to change the normal operation state to the stopped state, and generates a stopped log; the other is that when the elevator is in the stopped procedure, the main CPU receives the trigger request, triggers the elevator mainboard to change the stopped state to the normal operation state, and generates a normal log.

[0029] There are several ways to trigger elevator stop; simply select one of them for control:

[0030] 1)(Long press combination key): Press and hold the UP and DN buttons simultaneously until the preset first duration T1 (e.g., 6 seconds or more).

[0031] 2)(Specific timing operation): Within the preset second duration T2 (e.g., 6 seconds), press a specific button sequence in sequence (e.g., UP→DN→UP→DN, or DN→UP→DN, or UP six times, or DN six times, etc., which must be designed as an unconventional operation).

[0032] 3)(Long press + combination): First, long press the UP button to reach T3, keep holding it, and at the same time press the DN button and hold it to T4 (or vice versa).

[0033] 4) If there is only an UP button or only a DN button, pressing a single button will hold the button for a duration of T5.

[0034] Or by pressing the button a certain number of times (e.g., 11 times).

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
