A maintenance control method, system, electronic device, and storage medium

Abstract

This invention discloses a maintenance control method, system, electronic device, and storage medium. The maintenance control system includes a maintenance device and a control cabinet. When the maintenance device is used outside the hall, it is connected to the control cabinet outside the hall. When the maintenance device is used in the hoistway, it acquires maintenance information received after connecting to the elevator circuit. Based on the maintenance information, a transmitting device determines the first position of the maintenance device when connected to the elevator circuit. The second position of the elevator to be maintained is determined based on the maintenance information. It then determines whether the first and second positions are consistent. If they are, the maintenance device is controlled to perform fault detection; if not, a setting error warning signal is sent to the maintenance device. Furthermore, it eliminates the need for a large maintenance device on the car top or in the pit, requiring less installation space, making it suitable for applications with small hoistway dimensions, such as home elevators. Controlling the maintenance device based on the position consistency determination result ensures accurate execution of elevator maintenance commands.

Description

Technical Field

[0001] This invention relates to the field of maintenance control technology, and in particular to a maintenance control method, system, electronic device, and storage medium. Background Technology

[0002] Traditional designs for the hallway maintenance devices of home elevators are mainly based on passenger elevator products. Because they reference the design concepts of passenger elevator products, they use independent electrical components, resulting in a complex overall design, large size, and high cost.

[0003] Elevators can also have maintenance operation functions on the car top and in the pit. By configuring emergency stop switches, maintenance switches, maintenance up buttons, maintenance common buttons, and maintenance down buttons, functions such as stopping, maintenance up, and maintenance down control can be realized.

[0004] Each location is equipped with maintenance and operation devices, and the necessary installation positions need to be designed. However, in the case of household elevators, the shaft size is usually small, making it difficult to provide suitable installation space. Corresponding components also need to be configured, which increases both the configuration cost and the design difficulty.

[0005] Furthermore, configuring different maintenance operation devices at various locations may require the elevator control cabinet to be configured with multiple communication protocols, increasing the communication resource consumption of the control cabinet and resulting in low elevator maintenance efficiency. In addition, in order to ensure elevator safety, how to accurately carry out maintenance when only one location of the elevator needs to be inspected is also a problem that needs to be solved. Summary of the Invention

[0006] This invention provides a maintenance control method to address the problem that existing technologies for elevator maintenance increase the communication resources of the control cabinet due to multiple communication protocols, resulting in low elevator maintenance efficiency. It also addresses the issue of how to accurately perform maintenance.

[0007] In a first aspect, the present invention provides a maintenance control method applied to a control cabinet of a maintenance control system. The maintenance control system further includes a maintenance device. When the maintenance device is used outside the hall, the maintenance device is connected to the control cabinet. When the maintenance device is used in the hoistway, the maintenance device is connected to the electrical box of the hoistway. The electrical box of the hoistway is connected to the control cabinet. The hoistway includes a car top and a pit.

[0008] The maintenance control method includes:

[0009] The maintenance information received by the maintenance device after it is connected to the elevator circuit is obtained.

[0010] The device for transmitting the maintenance information determines the first location where the maintenance device is connected to the elevator circuit based on the maintenance information transmission device.

[0011] The second location of the elevator to be inspected is determined based on the inspection information.

[0012] Determine whether the first position and the second position are consistent;

[0013] If so, control the maintenance device to perform fault detection;

[0014] If not, a setting error message signal is sent to the maintenance device.

[0015] Secondly, the present invention provides a maintenance control system, comprising: a control cabinet and a maintenance device.

[0016] When the maintenance device is used outside the hall, the maintenance device is connected to the control cabinet. When the maintenance device is used in the hoistway, the maintenance device is connected to the electrical box of the hoistway, and the electrical box of the hoistway is connected to the control cabinet. The hoistway includes the car top and the pit.

[0017] The control cabinet includes:

[0018] The maintenance information acquisition module is used to acquire the maintenance information received by the maintenance device after it is connected to the elevator circuit.

[0019] The first position determination module is used to determine the first position where the maintenance device is connected to the elevator circuit based on the maintenance information sending device;

[0020] The second position determination module is used to determine the second position of the elevator to be inspected based on the inspection information.

[0021] The position consistency determination module is used to determine whether the first position and the second position are consistent;

[0022] The fault detection execution module is used to control the maintenance device to perform fault detection if the first position is consistent with the second position.

[0023] An error message module is used to send a setting error message signal to the maintenance device if the first position is inconsistent with the second position.

[0024] Thirdly, the present invention provides an electronic device, the electronic device comprising:

[0025] At least one processor; and

[0026] A memory communicatively connected to the at least one processor; wherein,

[0027] The memory stores a computer program that can be executed by the at least one processor, the computer program being executed by the at least one processor to enable the at least one processor to perform the maintenance control method described in the first aspect of the present invention.

[0028] Fourthly, the present invention provides a computer-readable storage medium storing computer instructions that, when executed by a processor, implement the maintenance control method described in the first aspect of the present invention.

[0029] This invention provides a maintenance control method applied to a control cabinet in a maintenance control system. The maintenance control system also includes a maintenance device. When the maintenance device is used outside the hall, it is connected to the control cabinet outside the hall. When the maintenance device is used in the hoistway, it is connected to the electrical box in the hoistway. The electrical box in the hoistway is connected to the control cabinet. The hoistway includes a car top and a pit. The maintenance control method includes: acquiring maintenance information received by the maintenance device after it connects to the elevator circuit; determining a first position of the maintenance device when it connects to the elevator circuit based on the maintenance information; determining a second position of the elevator to be maintained based on the maintenance information; determining whether the first position and the second position are consistent; if yes, controlling the maintenance device to perform fault detection; if no, issuing a setting error prompt signal to the maintenance device.

[0030] First, this embodiment only requires a single inspection device to inspect locations such as the elevator hall, car top, and pit, saving on associated components and reducing both configuration costs and design complexity. Furthermore, it eliminates the need for bulky inspection devices on the car top and in the pit, requiring less installation space, making it suitable for applications with smaller shaft dimensions, such as home elevators. Additionally, the control cabinet only needs to communicate with the same inspection device, requiring only one communication protocol, reducing communication resource usage and improving elevator maintenance efficiency.

[0031] Secondly, based on the aforementioned inspection device, the actual first position of the inspection device is determined by the inspection information sending device, and the second position of the elevator that the user wants to inspect is determined by the inspection information received by the inspection device. When the first position and the second position are consistent, it means that the installation position of the inspection device is accurate and fault detection can be performed. When they are inconsistent, it means that the installation position of the inspection device is inaccurate and a setting error prompt signal can be issued. This facilitates the automatic judgment of the installation position of the inspection device and the control of the inspection device based on the judgment result, which can ensure accurate inspection of a certain position in the elevator.

[0044] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0045] Example 1

[0046] Figure 1 This is a flowchart of a maintenance control method provided in Embodiment 1 of the present invention. The maintenance control method of this embodiment can be applied to the control cabinet of the maintenance control system and is applicable to the situation of elevator maintenance. The method can be executed by the maintenance control system, which can be implemented in hardware and / or software and can be configured in electronic equipment. Figure 2 This is a schematic diagram of a maintenance control system structure, such as... Figure 2 As shown, the maintenance control system includes a maintenance device 1 and a control cabinet 2. When the maintenance device 1 is used outside the hall, it is connected to the control cabinet 2. The hoistway includes a car top and a pit. An electrical box is installed in the hoistway and is connected to the control cabinet 2. When the maintenance device 1 is used in the hoistway, it is connected to the electrical box.

[0047] A maintenance device mounting cabinet is installed outside the elevator hall. During normal elevator operation or use outside the hall, the maintenance device is installed in this cabinet. When used on the car top or in the pit, the maintenance device is removed from the cabinet, moved to the car top or pit location, and connected to the electrical box on the car top or pit. For the control cabinet, regardless of whether it's on the car top, in the pit, or outside the hall, it communicates with the same maintenance device, simplifying the control cabinet's communication protocol. Furthermore, only one location is maintained at a time; communication (related to maintenance) at the other two locations is interrupted. This means that maintenance information is processed only at one location at a time, saving communication resources on the main control board and improving data processing efficiency.

[0048] The electrical control box is mainly used to protect and store the elevator's low-voltage power distribution equipment, such as switches, sockets, and wires. Its main function is to centralize electrical equipment in one box for convenient maintenance and management. It should be noted that the electrical control box is not the same as a maintenance device. The electrical control box serves as the interface for the maintenance device to connect to the elevator circuit, and also as an information acquisition device for the control cabinet.

[0049] An elevator control cabinet is an electrical control device that houses various electronic components and electrical parts within a safe, cabinet-shaped structure. The control cabinet contains the main control board and can also be called the elevator central control cabinet. The elevator control cabinet is used to control the operation of the elevator; therefore, maintenance equipment is usually connected to the elevator control cabinet for maintenance and control. Elevator control cabinets are generally located in the elevator machine room; for elevators without a machine room, the control cabinet is placed in the shaft.

[0050] like Figure 1 As shown, the maintenance control method includes:

[0051] S101. Obtain the maintenance information received by the maintenance device after it is connected to the elevator circuit.

[0052] As mentioned above, the maintenance device can be connected to the control cabinet or the electrical box. Therefore, in this step, the maintenance device can be connected to the elevator circuit either by connecting it to the control cabinet or by connecting it to the electrical box.

[0053] The maintenance device can be equipped with a wireless receiver, allowing maintenance information to be transmitted wirelessly from the outside world via methods such as Bluetooth or NFC. The device can also have buttons or levers for selecting maintenance locations. The device can determine the corresponding maintenance information by activating these devices. For example, if buttons A, B, and C correspond to the hall entrance, car top, and pit respectively, then pressing button B indicates that the user wants to inspect the elevator car top, and pressing button C indicates that the user wants to inspect the elevator pit.

[0054] S102. The device for transmitting maintenance information determines the first position where the maintenance device is connected to the elevator circuit.

[0055] The maintenance device can be connected to the control cabinet and electrical box, and the electrical box can also be connected to the control cabinet. That is, the maintenance device can communicate with the control cabinet, and the electrical box can also communicate with the control cabinet. Maintenance information from the maintenance device can also be sent to the control cabinet through the electrical box. Therefore, the location of the maintenance device when it is connected to the elevator circuit can be determined based on the device that sends the maintenance information. The electrical box and control cabinet in the hoistway can communicate via cable. In an optional embodiment, communication between the electrical box in the pit and the control cabinet uses a hoistway cable, and communication between the electrical box on the car top and the control cabinet uses a traveling cable. The hoistway cable and the traveling cable serve functions including power supply, signal control, and communication.

[0056] Specifically, the method for determining the first location of the maintenance device when it connects to the elevator circuit based on the transmission device of maintenance information includes: if the transmission device is the maintenance device, determining the first location of the maintenance device when it connects to the elevator circuit is outside the hall; if the transmission device is the electrical box in the pit, determining the first location of the maintenance device when it connects to the elevator circuit is in the pit; if the transmission device is the electrical box on the car top, determining the first location of the maintenance device when it connects to the elevator circuit is on the car top.

[0057] The first position is the actual location of the maintenance device.

[0058] S103. Determine the second position of the elevator to be inspected based on the inspection information.

[0059] The maintenance information indicates the location of the elevator that the user wants to have inspected. This information may include a second location for the elevator to be inspected. Furthermore, maintenance information can also be a maintenance mode. For example, maintenance modes include hall inspection mode, car top inspection mode, and pit inspection mode. These modes correspond to hall, car top, and pit, respectively. Therefore, when obtaining maintenance information (maintenance mode), the second location of the elevator to be inspected can also be determined based on this information.

[0060] The second location is the elevator that the user wants to have inspected.

[0061] S104. Determine whether the first position and the second position are consistent.

[0062] The first position is the actual location of the maintenance device, and the second position is the location of the elevator that the user wants to maintain. Determine whether the first position and the second position are consistent. If yes, execute S105; otherwise, execute S106.

[0063] S105. Control the maintenance device to perform fault detection.

[0064] When the location of the elevator that the user wants to inspect matches the actual location of the inspection device, it means that the inspection device is installed in place and elevator inspection can be carried out. Therefore, the inspection device can be controlled to perform fault detection.

[0065] S106. Send a setting error prompt signal to the maintenance device.

[0066] When the location of the elevator that the user wants to inspect is inconsistent with the actual location of the inspection device, it indicates that the inspection device is not installed properly or the inspection location (second location) set by the user is incorrect. Therefore, an error setting prompt signal can be sent to the inspection device.

[0067] In one optional embodiment, the maintenance device is equipped with a display for showing communication information between the maintenance device and the control cabinet. For example, the display shows elevator status information, such as car position, leveling position, and other prompts, based on data exchanged with the control cabinet. In one optional example, issuing a setting error prompt signal to the maintenance device includes sending the setting error prompt signal to the maintenance device for display on the maintenance device's display.

[0068] This invention provides a maintenance control method applied to a control cabinet in a maintenance control system. The maintenance control system also includes a maintenance device. When the maintenance device is used outside the hall, it is connected to the control cabinet outside the hall. When the maintenance device is used in the hoistway, it is connected to the electrical box in the hoistway. The electrical box in the hoistway is connected to the control cabinet. The hoistway includes a car top and a pit. The maintenance control method includes: acquiring maintenance information received by the maintenance device after it connects to the elevator circuit; determining a first position of the maintenance device when it connects to the elevator circuit based on the maintenance information; determining a second position of the elevator to be maintained based on the maintenance information; determining whether the first position and the second position are consistent; if yes, controlling the maintenance device to perform fault detection; if no, issuing a setting error prompt signal to the maintenance device.

[0069] First, this embodiment only requires a single inspection device to inspect locations such as the elevator hall, car top, and pit, saving on associated components and reducing both configuration costs and design complexity. Furthermore, it eliminates the need for bulky inspection devices on the car top and in the pit, requiring less installation space, making it suitable for applications with smaller shaft dimensions, such as home elevators.

[0070] Secondly, based on the aforementioned inspection device, the actual first position of the inspection device is determined by the inspection information sending device, and the second position of the elevator that the user wants to inspect is determined by the inspection information received by the inspection device. When the first position and the second position are consistent, it means that the installation position of the inspection device is accurate and fault detection can be performed. When they are inconsistent, it means that the installation position of the inspection device is inaccurate and a setting error prompt signal can be issued. This facilitates the automatic judgment of the installation position of the inspection device and the control of the inspection device based on the judgment result, which can ensure accurate inspection of a certain position in the elevator.

[0071] Example 2

[0072] Figure 3 This is a flowchart of a maintenance control method provided in Embodiment 2 of the present invention. The embodiments of the present invention are optimized based on Embodiment 1.

[0073] In this embodiment, Figure 4 This is a schematic diagram of the structure of a maintenance device, such as... Figure 4As shown, the maintenance device 1 includes a common module 11 and an external maintenance module 12. The common module 11 includes functional components that are shared when used outside the hall and in the shaft. The external maintenance module 12 includes functional components required when used outside the hall, in addition to the common module.

[0074] like Figure 4 As shown, the common module 11 includes a stop module 110, a power supply module 111, a communication module 112, and a maintenance operation control module 113. The power supply module 111 provides DC power, such as DC 24V, to the maintenance device 1.

[0075] In an optional embodiment, both the communication module and the maintenance control operation module are connected to the control cabinet. The communication module communicates and interacts with the control cabinet. After establishing an information connection with the control cabinet, the maintenance operation control module can provide point-to-point maintenance status information to the control cabinet, allowing the control cabinet to determine whether to enter the maintenance state.

[0076] like Figure 4 As shown, the hall-outdoor maintenance module 12 includes a main switch control module 120, a brake release control module 121, and a speed governor control module 122. The brake release control module 121 controls the elevator's brake by controlling the brake power supply; the stop module 110 is equivalent to a stop switch, used to control the elevator safety circuit to disconnect, thus stopping the elevator; the main switch control module 120 can remotely control the main circuit breaker installed in the control cabinet to connect or disconnect; the stop module 110 and the main switch control module 120 ensure that the safety circuit and the main switch are in normal condition; the speed governor control module 122, under the premise that the hall-outdoor maintenance switch is effective, drives the speed governor switch to be set or reset through the maintenance operation control module 113.

[0077] In an optional embodiment, such as Figure 4 As shown, the maintenance device 1 is provided with a first interface 13, through which the shared module 11 and the brake release control module 121 are connected to the outside. The maintenance device 1 is provided with a second interface 14, through which the main switch control module 120 is connected to the outside. The maintenance device 1 is provided with a third interface 15, through which the speed limiter control module 122 is connected to the outside.

[0078] like Figure 3 As shown, the maintenance control method includes:

[0079] S301. Obtain the maintenance information received by the maintenance device after it is connected to the elevator circuit.

[0080] S302, The device for transmitting maintenance information determines the first position where the maintenance device is connected to the elevator circuit.

[0081] In an optional embodiment, after the sending device for maintenance information determines the first position where the maintenance device is connected to the elevator circuit, the method further includes: when the first position is outside the hall, determining whether the shared module and the hall maintenance module are connected to the control cabinet based on the module connection information; if yes, executing the step of determining the second position of the elevator to be maintained based on the maintenance information; if no, determining that the maintenance device is not installed; when the first position is in the shaft, determining whether the shared module is connected to the electrical box of the corresponding shaft based on the module connection information; if yes, executing the step of determining the second position of the elevator to be maintained based on the maintenance information; if no, determining that the maintenance device is not installed.

[0082] In other words, when the maintenance device is used outside the hall, both the common module and the hall-side maintenance module must be connected to the control cabinet, meaning both are connected to the elevator's circuitry. When the maintenance device is used in the hoistway, only the common module needs to be connected to the corresponding hoistway electrical box; the hall-side maintenance module remains unconnected and in an inactive state. This is because the hall-side maintenance module is ineffective when the maintenance device is used on the car top or in the pit, thus it does not need to be connected to the circuitry. Specifically, the maintenance operation control module can provide point-to-point maintenance status information to the control cabinet; therefore, the module connection information can be collected and provided by the maintenance operation control module.

[0083] By obtaining the access status of the shared module and the external maintenance module, it is possible to accurately determine whether the maintenance device has been installed without manual confirmation, thereby improving the accuracy and efficiency of elevator maintenance.

[0084] S303. Determine the second position of the elevator to be inspected based on the inspection information.

[0085] S304. Determine whether the first position and the second position are consistent.

[0086] If not, execute S305; if yes, execute S306.

[0087] S305. Send a setting error warning signal to the maintenance device.

[0088] S301-S05 are similar to S101-S104 in Embodiment 1. For details, please refer to the relevant content of S101-S104, which will not be described here.

[0089] S306. Determine whether the first position is a shaft.

[0090] If yes, then execute S307; otherwise, execute S310.

[0091] The first position is the actual location of the maintenance device.

[0092] S307. Obtain switch connection information.

[0093] When the first position is the hoistway, that is, the actual position of the maintenance device is the pit or the car top, the maintenance device is connected to the electrical box of the corresponding hoistway, and obtains the switch connection information through the electrical box connected to the maintenance device.

[0094] S308. Determine whether the emergency stop switch box corresponding to the shaft is connected to the control cabinet based on the switch connection information.

[0095] Emergency stop switch boxes are respectively installed in the pit and on the car top, and the emergency stop switch boxes are respectively connected to the corresponding electrical boxes. The emergency stop switch boxes at the car top position and the pit position can be the same or different models, and the present invention does not limit this. Figure 5 This is a schematic diagram of an emergency stop switch box structure, such as... Figure 5 As shown. The emergency stop switch box has an emergency stop switch C, interface A, and interface B. The emergency stop switch C has at least two normally closed contacts. One contact is used for the elevator safety circuit. When this contact is open, the elevator safety circuit is disconnected. This contact is connected to the outside via interface A. The other contact is used in series with the main switch control circuit to replace the main switch control module of the maintenance device. When this contact is open, the main circuit breaker installed in the control cabinet will be disconnected. Only when this contact is closed can the main circuit breaker be connected. This contact is connected to the outside via interface B. When the emergency stop switch box is used on the car top or in the pit, only interface A is used to connect to interface A on the car top or in the pit. Interface B is not used and only functions as an emergency stop switch for the safety circuit. When the emergency stop box is used outside the hall, interface A and interface B are connected to interface A and interface B outside the hall, respectively. This emergency stop switch box replaces the stop module and main switch control module of the maintenance device.

[0096] When the first position is the hoistway, that is, the actual position of the maintenance device is the pit or the car top, since the maintenance device includes a stop module and a main switch control module, these two modules can ensure that the safety circuit and the main switch are in normal condition. When the maintenance device is moved to the pit or the car top, the stop module and the main switch control module are also moved away. At this time, the safety module is connected in series with the safety circuit in the hall position, so that the safety module performs the functions of the stop module and the main switch control module, ensuring that the safety circuit and the main switch are in normal condition.

[0097] Therefore, in order to ensure that the safety circuit and main switch are in normal condition, it is necessary to determine whether the emergency stop switch box corresponding to the shaft is connected to the control cabinet. If yes, execute S310; otherwise, execute S309.

[0098] Specifically, this includes the following two situations:

[0099] A first emergency stop switch box is installed on the car roof. The first emergency stop switch box is connected to the electrical box on the car roof. When the first position is the car roof, the first switch connection information is obtained. Based on the first switch connection information, it is determined whether the first emergency stop switch box is connected to the control cabinet. If yes, then S310 is executed; if no, then S309 is executed.

[0100] The pit is equipped with a second emergency stop switch box, which is connected to the electrical box in the pit. When the first position is the pit, the connection information of the second switch is obtained. Based on the connection information of the second switch, it is determined whether the second emergency stop switch box is connected to the control cabinet. If yes, S310 is executed; if no, S309 is executed.

[0101] S309. Send an emergency stop switch connection signal to the maintenance unit.

[0102] If the emergency stop switch box corresponding to the shaft is not connected to the control cabinet, it means that the safety circuit and the main switch cannot be guaranteed to be in normal condition. In this case, an emergency stop switch connection signal can be sent to the maintenance device to prompt the user or staff to connect the emergency stop switch box corresponding to the current shaft to the control cabinet.

[0103] S310, Control and maintenance device to perform fault detection.

[0104] In the first scenario, if the maintenance device is located outside the hall, then fault detection can be performed when the first and second positions coincide.

[0105] In the second scenario, when the first and second positions coincide, the maintenance device is located in the shaft. If the emergency stop switch box corresponding to the shaft is connected to the control cabinet, it indicates that the safety circuit and main switch can be in normal condition, and the maintenance device can be controlled to perform fault detection.

[0106] In an optional embodiment, after the maintenance control device performs fault detection, the method further includes: acquiring the elevator's operating command; when the operating command is to run at high speed, determining whether both the first position and the second position are outside the hall; if so, controlling the elevator to run at high speed. This is because running the elevator at high speed poses a safety hazard when performing maintenance on the elevator's car top position or pit position.

[0107] To clearly illustrate the connection methods between the maintenance device and the control cabinet and electrical box when the maintenance device is in different locations, the following examples and accompanying drawings will be used for explanation.

[0108] Example 1: The maintenance equipment is used outside the hall.

[0109] Figure 6 This is a schematic diagram showing the connection method of the maintenance equipment when it is used outside the hall; for example... Figure 6As shown, a first emergency stop switch box 21 and a first emergency stop switch box 22 are respectively installed on the car top and in the pit. On the car top, the first emergency stop switch box 21 is connected to the electrical box 23 on the car top, and both electrical boxes 22 and 23 are connected to the control cabinet 2. In the pit, the second emergency stop switch box 22 is connected to the electrical box 24 in the pit. Outside the hall, the common module 11 and the brake release control module 121 in the maintenance device 1 are connected to the control cabinet 2 via the first interface 13, the main switch control module 120 is connected to the control cabinet 2 via the second interface 14, and the speed limiter control module 122 is connected to the speed limiter 25 via the third interface 15 to control the speed limiter 25. At this time, the control cabinet 2 only receives maintenance information from outside the hall. When the maintenance device 1 is equipped with selection buttons, selecting the button corresponding to the maintenance outside the hall can realize the functions of maintenance operation control and emergency stop switch.

[0110] It should be noted that the control cabinet is equipped with multiple interfaces. These interfaces provide control signals for the main circuit breaker of the control cabinet to be turned on and off, as well as interfaces for connecting the DC power supply, communication circuit, maintenance operation control circuit, and emergency stop switch safety circuit to the electrical box in the hoistway. For the communication circuit, each interface can be connected in parallel to the same communication interface on the main control board in the control cabinet. Different locations can be distinguished using different communication protocols of the maintenance device, or each interface can be connected to a different communication interface on the main control board of the control cabinet; there are no restrictions on this.

[0111] Example 2: The maintenance device is used on the car top.

[0112] Figure 7 This is a schematic diagram showing the connection method of the maintenance device when used on the car top; for example... Figure 6 As shown, the original car top and pit are respectively equipped with a first emergency stop switch box 21 and a first emergency stop switch box 22, as follows: Figure 7 As shown, when the maintenance device 1 is used on the car roof, in the car roof section, the common module 11 of the maintenance device 1 is connected to the electrical box 23 on the car roof via the first interface 13, and the maintenance module 12 outside the hall is in an inactive state. In the pit section, the second emergency stop switch box 22 is connected to the electrical box 24 in the pit. In the hall section, the first emergency stop switch box 21, originally installed on the car roof, is connected to the control cabinet 2, and the speed limiter 25 is not connected. At this time, the control cabinet 2 only receives maintenance information from the car roof location.

Through this interface, the DC power supply, communication circuit, maintenance operation control circuit, and car top emergency stop switch safety circuit are connected to the interface of the car top electrical box. When using the maintenance device 1 on the car top, first press the emergency stop switch of the emergency stop switch box 21 to disconnect the elevator safety circuit, and then remove the emergency stop switch box 21. The main circuit breaker is then disconnected via the main switch control module 120 of the maintenance device 1, cutting off the elevator power supply. Then, the connections of the three interfaces in the maintenance device 1 are disconnected, and the emergency stop switch box 21 is connected to the control cabinet 2, replacing the functions of the stop module 110 and the main switch control module 120 in the maintenance device 1. By restoring the emergency stop switch of the emergency stop switch box 21, control of the safety circuit outside the hall and the main circuit breaker is restored, and the elevator power supply is restored. If the emergency stop switch of the emergency stop switch box 21 is pressed, the elevator safety circuit will be disconnected, and the main circuit breaker will be disconnected, cutting off the elevator power supply. The maintenance device 1 is connected to the electrical box 23 on the car top, which provides DC power, communication circuit, maintenance operation control circuit, and car top emergency stop switch for the maintenance device 1.

Figure 6 As shown, the original car top and pit are respectively equipped with a first emergency stop switch box 21 and a first emergency stop switch box 22, as follows: Figure 8 As shown, when the maintenance device 1 is used in the pit, in the pit section, the common module 11 of the maintenance device 1 is connected to the electrical box 24 in the pit through the first interface 13, and the maintenance module 12 outside the hall is in an inactive state. In the car roof section, the first emergency stop switch box 21 is connected to the electrical box 23 on the car roof. In the hall section, the second emergency stop switch box 22, originally installed in the pit, is connected to the control cabinet 2, and the speed limiter 25 is not connected. At this time, the control cabinet 2 only receives maintenance information from the pit location.

[0116] Specifically, the electrical box 24 in the pit connects the DC power supply, communication circuit, maintenance operation control circuit, and pit emergency stop switch safety circuit to the interface of the pit maintenance box through its interface. When using the maintenance device 1 in the pit, first press the emergency stop switch of the emergency stop switch box 22 to disconnect the elevator safety circuit, and then remove the emergency stop switch box 22. Control the main circuit breaker to disconnect the power supply to the elevator through the main switch control module 120 of the maintenance device 1, and then disconnect the connection of the three interfaces in the maintenance device 1. Connect the emergency stop switch box 22 to the control cabinet 2 respectively, replacing the functions of the stop module 110 and the main switch control module 120 of the maintenance device 1. If the emergency stop switch of the emergency stop switch box 22 is pressed, the elevator safety circuit will be disconnected, and the main circuit breaker will be disconnected, thus disconnecting the power supply to the elevator. By restoring the emergency stop switch of the emergency stop switch box 22, the control of the safety circuit outside the hall and the main circuit breaker is restored, and the power supply to the elevator is restored. The maintenance device 1 is connected to the interface of the maintenance box 24 in the pit, providing the maintenance device 1 with DC power, communication circuit, maintenance operation control circuit, and pit emergency stop switch. When the maintenance device 1 is equipped with a selection button, selecting the button corresponding to the pit maintenance can realize the functions of pit maintenance operation control and emergency stop switch.

[0117] This embodiment determines whether the first location is a hoistway before the maintenance device performs fault detection. If so, it acquires switch connection information and determines whether the emergency stop switch box corresponding to the hoistway is connected to the control cabinet based on the switch connection information. If so, it controls the maintenance device to perform fault detection; otherwise, it sends an emergency stop switch connection signal to the maintenance device. Since the maintenance device includes a stop module and a main switch control module, these two modules ensure that the safety circuit and main switch are in normal condition. When the maintenance device is moved to the pit or car top, the stop module and main switch control module are also moved. At this time, the safety module is connected in series with the safety circuit outside the hall, allowing the safety module to perform the functions of the stop module and main switch control module, ensuring that the safety circuit and main switch are in normal condition. When the maintenance device is used in the hoistway location, confirming the connection of the emergency stop switch box to the control cabinet ensures that the safety circuit and main switch are in normal condition.
