[0042] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0043] The elevator hall door control method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store data that server 104 needs to process. The data storage system can be integrated with server 104, or placed on a cloud or other network server. Server 104 obtains the power status of the elevator door motor. When the power status indicates that the elevator door motor is in a power-off condition, server 104 obtains the output signal of the elevator door motor encoder. Based on the output signal, server 104 determines the door opening distance of the elevator hall door. When the door opening distance is greater than a preset distance, server 104 reduces the closing speed of the elevator hall door until the hall door is closed. Terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, smart car devices, etc. Portable wearable devices can include smart watches, smart bracelets, head-mounted devices, etc. Server 104 can be implemented as a standalone server or a server cluster consisting of multiple servers.

[0044] In an exemplary embodiment, Figure 2 As shown, a method for controlling an elevator hall door is provided. Figure 1 The server 104 in the example is used as an example to illustrate the process, including the following steps 202 to 206.

[0045] Step 202: Obtain the power supply status of the elevator door motor.

[0046] The door motor may be a transmission device installed on the hall door of the elevator to control the opening and closing of the hall door of the elevator.

[0047] The hall door of an elevator refers to a door that can be seen from outside the elevator and is fixed on each floor.

[0048] The power supply state may refer to a power-on state or a power-off state of a main circuit of the door motor.

[0049] Optionally, the server obtains the power supply status of the elevator door motor to determine whether the elevator door motor is powered on.

[0050] Step 204 : When the power supply state indicates that the elevator door motor is in a power-off state, an output signal of the elevator door motor encoder is obtained.

[0051] The power-off condition may refer to a condition when the door motor loses external power supply.

[0052] Among them, the door motor encoder can be a device that compiles and converts signals or data into a signal form that can be used for communication, transmission and storage.

[0053] The output signal may refer to a feedback signal carrying information on the opening distance of the elevator's hall doors.

[0054] Optionally, the server determines whether the current elevator door motor is in a power-off condition based on the power supply status. When it is determined that the current elevator door motor is in a power-off condition, the server obtains the output signal of the elevator door motor encoder.

[0055] Step 206: Determine the door opening distance of the elevator hall door according to the output signal.

[0056] Optionally, the server determines the door opening distance of the elevator's hall door based on an output signal of the elevator's door motor encoder.

[0057] Step 208: When the door opening distance is greater than the preset distance, the closing speed of the elevator hall door is reduced until the hall door is closed.

[0058] The preset distance may be a preset value. In practical applications, the preset distance may be set to 200 mm.

[0059] The door closing speed may be the closing speed of the elevator hall door when the door is closed.

[0060] Optionally, when the opening distance of the hall door of the elevator is greater than a preset distance, the server reduces the closing speed of the hall door of the elevator so that the hall door of the elevator closes slowly.

[0061] In the above-mentioned elevator hall door control method, the power supply status of the elevator door motor is obtained; when the power supply status indicates that the elevator door motor is in a power-off condition, the output signal of the elevator door motor encoder is obtained; based on the output signal, the door opening distance of the elevator hall door is determined; when the door opening distance is greater than a preset distance, the closing speed of the elevator hall door is reduced until the hall door is closed; in this way, when it is determined that the elevator door motor is in a power-off condition, if the door opening distance of the elevator hall door is large, the closing speed of the elevator hall door can be automatically reduced, which is beneficial to reduce the abnormal noise of the hall door closing, improve the comfort of passengers in the elevator, and at the same time reduce the closing speed of the elevator hall door that pinches people, thereby improving the safety of the elevator.

[0062] In an exemplary embodiment, Figure 3 As shown, step 202 includes steps 302 to 304. Among them:

[0063] Step 302: Detect the power supply status of the main circuit of the elevator door motor through the intelligent probe.

[0064] The smart probe may be a probe with an intelligent detection circuit.

[0065] The power supply status of the main circuit may indicate whether the main circuit is powered by an external power supply.

[0066] Optionally, the server detects via an intelligent probe whether the main circuit of the elevator door motor is powered by an external power supply.

[0067] Step 304: Determine the power supply status of the elevator door motor according to the power supply status of the main circuit.

[0068] Optionally, the server determines the current power supply status of the elevator door motor according to whether the main circuit is powered by an external power supply.

[0069] In this embodiment, the power supply condition of the main circuit of the elevator door motor is detected by an intelligent probe, and then the power supply status of the elevator door motor is determined based on the power supply condition of the main circuit. In this way, whether the power supply of the main circuit of the elevator door motor is normal can be detected by the intelligent probe, thereby accurately judging the power supply status of the elevator door motor.

[0070] In an exemplary embodiment, the main circuit power supply condition of the elevator door motor is detected by an intelligent probe, including: continuously detecting the main circuit current value or the main circuit power value of the elevator door motor within a detection period by the intelligent probe; and determining that the main circuit power supply of the elevator door motor is abnormal within the detection period by the intelligent probe when the main circuit current value is less than a preset current threshold or the main circuit power value is less than a preset power threshold.

[0071] The detection period may refer to any pre-divided time period.

[0072] The main circuit current value may refer to a value corresponding to the current of the main circuit.

[0073] The main circuit power value may refer to a value corresponding to the power of the main circuit.

[0074] The preset current threshold may refer to a preset threshold for the main circuit current.

[0075] The preset power threshold may refer to a preset threshold for the main circuit power.

[0076] Optionally, the main circuit current value or main circuit power value of the elevator door motor is continuously detected by the smart probe during the detection period, and then, when the main circuit current value is less than a preset current threshold or the main circuit power value is less than a preset power threshold, the smart probe determines that the main circuit power supply of the elevator door motor is abnormal during the detection period.

[0077] In this embodiment, the main circuit current value or main circuit power value of the elevator door motor is continuously detected by the intelligent probe during the detection period, and then the main circuit power supply of the elevator door motor is determined to be abnormal during the detection period when the main circuit current value is less than a preset current threshold or the main circuit power value is less than a preset power threshold by the intelligent probe. The preset current threshold or power threshold can be compared with the detected current value or power value to automatically determine whether the main circuit power supply of the elevator door motor is abnormal, thereby accurately determining the current condition of the elevator door motor.

[0078] In an exemplary embodiment, when the door opening distance is greater than a preset distance, the closing speed of the elevator's hall door is reduced until the hall door is closed, including: when the door opening distance is greater than the preset distance, the elevator's door motor is shut down to control the elevator's door motor to enter an idle operation state; wherein the idle operation state indicates that the elevator's door motor is operating under no-load conditions; the idle operation state is used to reduce the closing speed of the elevator's hall door until the hall door is closed.

[0079] The idle operation state may refer to a working state corresponding to when the door motor of the elevator operates under no-load conditions.

[0080] Optionally, when the opening distance of the elevator's hall door is greater than a preset distance, the server performs a star-off process on the elevator's door motor, so that the door motor is short-circuited in three phases to control the elevator's door motor to enter an idle operation state, slowing down the closing speed of the elevator's hall door until the elevator's hall door is closed.

[0081] In this embodiment, the elevator door motor is shut down when the door opening distance is greater than a preset distance to control the elevator door motor to enter an idle operation state. The elevator door motor can be operated under no-load conditions to slow down the closing speed of the elevator hall door, so that the elevator hall door can be slowly closed until it is closed.

[0082] In an exemplary embodiment, the method further includes: when the power supply state indicates that the door motor of the elevator is in a powered-on state, controlling the door motor of the elevator to be in a normal operating state so that the hall door of the elevator operates normally.

[0083] The power-on working condition may refer to a working condition when the door motor is powered by an external power supply.

[0084] Optionally, when the power supply state indicates that the door motor of the current elevator is in a powered-on state, the server controls the door motor of the elevator to be in a normal operating state, so that the hall door of the elevator can operate normally.

[0085] In this embodiment, by controlling the elevator door motor to be in a normal operating state when the power supply state indicates that the elevator door motor is in an energized condition, the elevator hall door can operate normally, and the normal operation of the elevator hall door can be guaranteed when it is determined that there is no need to reduce the closing speed of the elevator hall door.

[0086] In an exemplary embodiment, the method further includes: when the hall door opening distance is less than or equal to a preset distance, controlling the hall door of the elevator to enter an intelligent standby mode so that the hall door of the elevator closes normally.

[0087] The intelligent standby mode may refer to a state corresponding to when the hall door of the elevator is not operated.

[0088] Optionally, when the opening distance of the hall doors is less than or equal to a preset distance, the server controls the hall doors of the elevator to enter an intelligent standby mode so that the hall doors of the elevator can be closed normally.

[0089] In this embodiment, when the hall door opening distance is less than or equal to the preset distance, the elevator's hall door is controlled to enter the intelligent standby mode so that the elevator's hall door is closed normally. The closing mode of the elevator's hall door can be flexibly and accurately adjusted according to the size comparison between the hall door opening distance and the preset distance.

[0090] To facilitate understanding by those skilled in the art, Figure 4An exemplary structural diagram of an elevator hall door control device is provided, which mainly includes an intelligent detection probe, an emergency control module, a normal control module, a PWM drive module, an energy storage filter module, and a door motor. The intelligent detection probe can determine whether the main circuit power supply of the elevator door motor is normal by detecting the voltage and current values ​​of the power supply on the elevator door motor side. The emergency control module includes a signal receiving module, a signal transmitting module, a safety protection module, an energy storage feedback module, and an execution module. The energy storage feedback module is used to receive the power provided by the energy storage filter module to ensure the operation of the emergency control module. The normal control module includes a signal receiving module, a signal transmitting module, a safety protection module, and an execution module. The signal receiving module is used to immediately receive and read the feedback signal from the intelligent detection probe. The signal transmitting module is used to transmit the signal to the safety protection module and the execution module. The safety protection module is used to effectively protect the operation of the normal control module and, in extreme cases, immediately cut off the connection between the normal control module and the outside world. The execution module is used to start the PWM drive module after receiving the correct instruction.

[0091] In actual applications, the intelligent detection probe is used to promptly identify whether the mains power is normally supplied. According to the set current threshold or power threshold, it is compared with the detected current value or power value, and the current value and current threshold, power value and power threshold within the detection cycle are compared. It automatically determines whether the door motor is in a power-off state and outputs a signal to drive the emergency control module or the normal control module. Then, when the elevator door motor is in a power-off state, the energy storage filter module is activated, the emergency control module is triggered, and the three-phase star of the door motor is shut off. In order to facilitate the understanding of those skilled in the art, Figure 5 A flow chart of an elevator hall door control method is provided as an example. Figure 4 The elevator hall door control device shown in FIG. 1 includes the following specific steps:

[0092] Step 1: Use the intelligent detection probe to continuously detect the current or voltage of the door motor main circuit during the detection period to determine whether the door motor is normally powered.

[0093] Step 2: The door motor is normally powered on, the normal control module works, and the PWM drive module controls the door motor to operate normally.

[0094] Step 3: When the hall door is in the closed state, the door motor is in the normal operation mode.

[0095] Step 4: When the door motor is in a momentary power outage, activate the energy storage filter module to supply power to the emergency control module.

[0096] Step 5: The emergency control module starts working and enters the emergency control operation mode.

[0097] Step 6: The emergency control module reads the feedback signal from the door motor encoder to determine whether the hall door opening distance is greater than 200 mm.

[0098] Step 7: If the door opening distance is ≤200mm, the hall door will directly enter the intelligent standby mode and close automatically.

[0099] Step 8: If the door opening distance is greater than 200mm, the three-phase short-circuit state of the door motor is realized through the PWM drive module.

[0100] Step 9: The door motor runs at idle speed to slow down the closing speed of the hall door.

[0101] Step 10: Slowly close the hall door until it is fully closed.

[0102] Step 11: The emergency control state ends.

[0103] In an exemplary embodiment, Figure 6 As shown, a method for controlling an elevator hall door is provided. Figure 1 Taking the server 104 in the example as an example, the following steps are included:

[0104] Step 602: Detect the power supply status of the main circuit of the elevator door motor through the intelligent probe.

[0105] Step 604: Determine the power supply status of the elevator door motor according to the power supply status of the main circuit.

[0106] Step 606: When the power supply status indicates that the elevator door motor is in a power-off state, an output signal of the elevator door motor encoder is obtained.

[0107] Step 608: Determine the door opening distance of the elevator hall door according to the output signal.

[0108] Step 610: When the door opening distance is greater than the preset distance, the closing speed of the elevator hall door is reduced until the hall door is closed.
