[0002] Construction hoists (also called construction elevators or construction ladders) are widely used in building construction for the up and down transportation of building materials and personnel.

[0025] The step of determining the target floor stop result based on the floor call instruction and the current operation information includes:

[0026] Determine whether the direction of the floor call instruction is the same as the first direction of the current operation;

[0060] Construction hoists (also called construction elevators or construction ladders) are widely used in building construction for the up and down transportation of building materials and personnel.

[0061] Traditional construction elevator control systems usually use simple judgment logic based on a single factor to determine whether the car is allowed to operate. For example, when the weight exceeds a certain fixed threshold, the system will trigger an overload alarm and stop operation.

[0062] However, this simple control strategy based on a single factor is rather one-sided and can easily lead to low control accuracy of the construction hoist control system.

[0063] In order to solve the above technical problems, the present application provides a control method for an elevator, which can improve the above technical problems.

[0064] First, the control system of the construction elevator provided by this application is introduced. Figure 1-4 As shown, the control system of the construction elevator provided by this application is mainly composed of four parts: the first part is the automatic leveling and motion control part of the car door machine, the second part is the floor selection control part (internal call) in the car, the third part is the first floor parallel dispatching control box, and the fourth part is the external call box.

[0065] Among them, the first part and the second part in the car can be 1 set or 2 sets. If it is 1 set, the construction elevator is a single-elevator operation. If it is 2 sets, the construction elevator is a double-elevator operation independently or a double-elevator operation in parallel (that is, parallel operation). The number of external call boxes depends on the number of floors, and one external call box can be set for each floor.

[0066] Specifically, see Figure 1 The first part, namely the automatic leveling and door machine motion control part in the car, is mainly controlled by the first controller 01, and the second part, namely the floor selection control part (internal call) in the car, is mainly controlled by the second controller 02. These two parts are introduced separately below.

[0067] Among them, the first controller 01 has an encoder interface 4, a limit protection interface 6, a first interactive interface 7 and a manual command control module 5, and establishes a control network with the frequency conversion inverter part, jointly controlling the first motor 1 (i.e., the main drive motor) and the second motor 10 (i.e., the car door motor), and is also provided with an overweight sensor 3 for overweight detection, etc.

[0068] The first controller 01 in the car mainly completes basic position detection, floor learning, overweight detection, up and down movement and leveling, as well as the opening and closing of the car door, etc. For example, after the construction ladder is installed, in manual mode, the user can input commands in the manual command control module 5 to control the car to move up and down, reach the target floor, and stop after completing the leveling.

[0069] In addition, the user can also realize floor number memory, floor position memory, etc. by operating the first interactive interface 7. In this process, various safety limits are also effective. For example, if the upper limit is encountered in the upward direction, the machine will stop.

[0070] The first controller 01 and the second controller 02 in the car are connected via a communication port. The first controller 01 can receive a target floor command from the second controller 02 and also transmit its own information to the second controller 02 .

[0071] Among them, the second controller 02 mainly includes a number detection interface 11, an inclination detection interface 12, a floor selection panel 13, a floor selection indicator light 14, a first wireless module 15 such as LoRa and a voice module 16.

[0072] The number detection interface 11 is used to detect the number of people in the car, the inclination detection interface 12 is used to detect the inclination of the car, and the floor selection panel 13 is used for users in the car to click and operate to select the specific floor to be reached. In addition, the floor selection panel 13 can also realize floor selection memory, floor shielding, floor deletion and other processing.

[0073] The second controller 02 can establish wireless communication with the first-floor parallel dispatch control box through the first wireless module 15, such as LoRa, to output the most appropriate floor command to the first controller 01 in combination with the external target floor given by the first-floor parallel dispatch control box.

[0074] in addition, Figure 1 In the embodiment, the motion control part of the automatic leveling and car door machine in the car provided by the present application is integrated with the floor selection control part in the car. In other embodiments, in order to facilitate the layout and operation in the car, the motion control part of the automatic leveling and car door machine in the car is separated from the floor selection control part in the car.

[0075] For the first-floor parallel dispatch control box, it is usually installed on the lowest floor, but it can actually be installed on other floors. Figure 2 The first-floor parallel dispatch control box is mainly controlled by the third controller 03, which includes a floor door component detection module 20, a button 21 (such as up and down elevator buttons), a second wireless module 25 such as LoRa, a first limit detection interface 23 and a CAN bus interface.

[0076] The first-layer parallel dispatch control box is connected to the second controller 02 via a wireless module 25 such as LoRa, and is connected to all external boxes via a CAN bus.

[0077] The three types of the floor door component detection module 20, the button 21 (such as the up and down elevator buttons) and the first limit detection interface 23 can be a group (such as Figure 2 For example, if the construction elevator is operated with a single elevator, the first-floor parallel dispatching control box is provided with a set of floor door component detection modules 20, buttons 21 (such as up and down elevator buttons) and a first limit detection interface 23; if the construction elevator is operated with two elevators or parallel elevators, the first-floor parallel dispatching control box is provided with two sets of floor door component detection modules 20, buttons 21 (such as up and down elevator buttons) and a first limit detection interface 23.

[0078] See also Figure 3 All external call boxes are connected to the parallel dispatch control box on the first floor through the CAN bus. The external call box is responsible for collecting the up and down elevator call signals of each floor, displaying the floor, and can drive the door of this floor to open and close synchronously with the car door.

[0079] Each external move box can be controlled by a main controller, for example, one of the external move boxes can be controlled by a fourth controller, such as Figure 3 As shown, the fourth controller 04 may include up and down keys 30 (ie, up and down elevator buttons), a second limit detection interface 32, a button indicator light 31, a floor door detection interface 33, and an information display light 34 (ie, an information display component).

[0080] Similarly, the second limit detection interface 32, the floor door detection interface 33, and the information display light 34 (ie, the information display component) can be a group (eg, Figure 3 as shown) or two groups.

[0081] For example, if the construction elevator is operated with a single elevator, the second limit detection interface 32, the floor door detection interface 33, and the information display light 34 (i.e., the information display component) are a group; if the construction elevator is operated with two elevators or parallel elevators, the second limit detection interface 32, the floor door detection interface 33, and the information display light 34 (i.e., the information display component) are two groups.

[0082] In some embodiments, the landing door and the car door in the present application can be opened and closed synchronously through mechanical linkage.

[0083] In other embodiments, the floor door and the car door in the present application may also be controlled separately and independently. For example, the floor door may be controlled by a control signal sent by a host computer in the car door to achieve synchronous opening and closing.

[0084] Because some existing unmanned driving systems use wireless transmitter boxes for external calls, two-way interaction is impossible, only one-way elevator calls are possible, and host information such as floors cannot be displayed; this wireless transmitter box is battery-powered and cannot detect various limit signals of floor doors, let alone control floor doors, and has not essentially achieved complete unmanned driving.

[0085] In addition, the transmission distance of this universal wireless transmitter box is limited. When the wireless signal is at a high floor, it is very poor, which can easily affect the stable operation of the system. The unmanned driving system is relatively complex, with many signals. If a limit is faulty or the floor door is opened, the car should stop running, especially since the limit of each floor door is distributed on each floor, which makes verification very troublesome.

[0086] In addition, existing control systems generally detect weight but do not detect the number of people in the car or the tilt angle of the elevator, which can easily lead to safety hazards.

[0087] In the control system of the above-mentioned construction elevator provided by the present application, the systems inside and outside the car can communicate wirelessly, the host in the car can store floor data, and automatically operate according to the selected floor, and can operate with a single cage, a double cage, and intelligent scheduling of the double cages. The system in the car can detect the limit signal of the car and realize the automatic opening and closing of the car door. The external call box is wired to display the host information such as the floor, detect the floor door limit, and control the synchronous automatic opening and closing of the floor door and the car door. The number of passengers can be detected in the car, the car can stop in case of overcrowding, and voice broadcasts of various faults and prompts are supported. The control system of the above-mentioned construction elevator provided by the present application can be automatically operated without the need for a full-time driver, which reduces the cost of use and facilitates the status monitoring and maintenance of each limit sensor.

[0088] Based on the control system of the construction elevator, the present application provides a control method for the elevator, referring to Figure 4 , Figure 4 This is a flow chart of a first embodiment of a control method for an elevator provided in the present application, the method comprising:

[0089] Step 110: Obtain the floor call instruction of the construction elevator and the preset operation mode of the construction elevator.

[0090] The floor call command may be a call command for one floor or a call command for multiple floors.

[0091] In some implementations, the floor outbound call instruction may be obtained by collecting information from an outbound call box. For example, when a user clicks an up button on the outbound call box, the outbound call box triggers the floor outbound call instruction and sends the floor outbound call instruction to the first-floor parallel box.

[0092] Among them, the preset operation modes of the construction elevator may include a single-elevator operation mode, a double-elevator operation mode, and a parallel-elevator operation mode.

[0093] In some embodiments, the preset operating mode of the construction elevator may be determined in advance by construction personnel, such as electricians, who select some functional parameters after the decoration of the construction elevator is completed; or it may be a floor selection control part in the car, with some modes set in advance for users to choose, such as double elevator mode, parallel elevator mode, etc. When the user selects one of the modes in the floor selection control part in the car, the preset operating mode of the construction elevator can be obtained.

[0094] Step 120: Obtain the calibrated floor list of the car and the current operation information of the car.

[0095] Among them, the calibrated floor list can be the floor number information memorized by the car after floor learning.

[0096] In some implementations, the operation flow of floor learning may be:

[0097] Complete the installation of the construction elevator → Manually run up and down for debugging → Return to the lowest floor → Enter the password in HM I to enter the floor calibration interface → Delete all floors (can be omitted for the first installation) → Enter the lowest floor number and calibrate → Manually run to the target floor, and adjust the leveling position so that the bottom of the car is level with the floor → Enter the target floor number and press the calibration button to complete the floor calibration.

[0098] Among them, except the lowest floor which must be learned first, there is no order requirement between the other floors. In this way, a calibrated floor list can be obtained.

[0099] For example, the floors are 1-15, and the calibrated floor list includes 1-10 floors, that is, 11-15 floors are uncalibrated floors. Therefore, even if the user presses the external call button on the 11-15 floors, there will be no response to the floor external call command on the 11-15 floors.

[0100] In some embodiments, the current operation information of the car may include the current number of people in the car, the current first direction of operation, the current operation position, the range of floors where the car stops, etc.

[0101] Step 130: Determine the target floor stop result of the elevator based on the floor call instruction, the preset operation mode, the calibrated floor list, and the current operation information.

[0102] This embodiment makes a comprehensive judgment by combining multiple factors such as floor call instructions, the preset operating mode, the calibrated floor list, and the current operating information, so that the final determined result of the elevator target floor stop is more accurate and comprehensive, thereby improving the existing method. The simple control strategy based on a single factor is relatively one-sided, resulting in low accuracy of construction elevator control system regulation.

[0103] In some implementations, the target floor stop result of the car may be determined based on the floor call instruction, the preset operation mode, the calibrated floor list, the current operation information and the fault information.

[0104] The fault information may be a problem with the motor drive. For example, if there is a problem with the motor drive on the 3rd floor, the door on the 3rd floor cannot be opened normally, but other signals are good.

[0105] If the fault information is other problems, such as abnormal disconnection of the limit, it means that the floor door is abnormally opened. Since the floor door is opened, it is very dangerous, and people or objects may fall, or the car may accidentally hit the door. Therefore, at this time, you can take protective measures such as stopping the machine and alarming.

[0106] In addition, if the fault information is that the driving device itself is faulty, the car will also stop running.

[0107] In some embodiments, the construction elevator is provided with a car, the number of cars is 1, and the preset operation mode of the construction elevator is a single elevator operation mode. Specifically, referring to the second embodiment of a control method for an elevator provided in the present application, the method includes:

[0108] Step 210: Obtain the floor call instruction of the construction elevator and the preset operation mode of the construction elevator.

[0109] Step 220: Obtain the calibrated floor list of the car and the current operation information of the car.

[0110] Step 230: Determine whether the floor number of the floor call instruction belongs to the calibrated floor list.

[0111] For example, the floors are 1-15, and the calibrated floor list includes 1-10 floors, that is, 11-15 floors are uncalibrated floors. If the floor call command is an up call command for the 5th floor, a down call command for the 6th floor, and a down call command for the 11th floor, it can be determined that the up call command for the 5th floor and the down call command for the 6th floor belong to the calibrated floor list.

[0112] Step 240: If the floor number of the floor call instruction belongs to the calibrated floor list, the target floor stop result of the car is determined based on the floor call instruction and the current operation information.

[0113] In some embodiments, the current operation information includes the first direction of the current operation and the internal call instruction.

[0114] Determining the target floor stop result of the car based on the floor call instruction and the current operation information in step 240 may specifically include the following steps:

[0115] Step 241: Determine whether the direction of the floor call instruction is the same as the first direction of the current operation.

[0116] Step 242: If the direction of the floor call instruction is the same as the first direction of the current operation, determine whether the floor call instruction is within the stop range of the first direction.

[0117] Step 243: If the floor external call instruction is within the stopping range of the first direction, respond to the floor external call instruction when responding to the internal call instruction in the first direction.

[0118] For example, the floor external call command is an upward external call command for the 5th floor, the current first direction of operation is upward, the current stopping position is the 3rd floor, and the internal call command is the 4th floor and the 6th floor. The direction of the floor external call command is the same as the current first direction of operation, and the upward external call command for the 5th floor is within the stopping range of the current first direction of operation. Therefore, after the car stops at the 4th floor level, it will first stop at the 5th floor to respond to the floor external call command.

[0119] For example, the floor external call command is an upward external call command for the 7th floor, the current first direction of operation is upward, the current stopping position is the 3rd floor, and the internal call command is for the 4th and 6th floors. The direction of the floor external call command is the same as the current first direction of operation, and the upward external call command for the 7th floor is within the stopping range of the current first direction of operation. Therefore, after the car stops at the 6th floor, it will continue to run along the first direction to the 7th floor for leveling, in response to the floor external call command.

[0120] Step 244: If the floor call instruction is not within the stopping range in the first direction, respond to the floor call instruction when the elevator car runs in the first direction next time.

[0121] For example, the current operating position of the car is the 4.5th floor, the current first operating direction is upward, and the internal call instructions are for the 6th and 7th floors. At this time, the floor external call instruction is an upward external call instruction for the 5th floor. Although the direction of the floor external call instruction is the same as the current first operating direction, the current operating position of the car has run to the 4.5th floor, and the upward external call instruction for the 5th floor is not within the stopping range of the first direction. Therefore, the car will not respond to the floor external call instruction on the 5th floor during this upward process, but will stop at the 7th floor and then descend. After descending, it will ascend again to the 5th floor to stop in response to the floor external call instruction.

[0122] In some embodiments, if the direction of the floor call instruction is different from the first direction of current operation, the floor call instruction is responded to when the elevator car is running in the opposite direction of the first direction.

[0123] For example, the floor external call command is a downward external call command for the 5th floor, the current first direction of operation is upward, the internal call commands are for the 2nd and 7th floors, and the current stop position is the 3rd floor. Since the direction of the floor external call command is different from the current first direction of operation, the car will stop at the 7th floor and then descend to the 5th floor, that is, the car will respond to the floor external call command when it is running in the opposite direction of the first direction.

[0124] In combination with the second embodiment, for example, the floor external call instructions include an upward external call instruction for the 5th floor, a downward external call instruction for the 6th floor, and a downward external call instruction for the 11th floor; the preset operation mode is single elevator operation; the floors are 1-15, and the calibrated floor list includes 1-10 floors, that is, 11-15 floors are uncalibrated floors, the internal call instructions are 3rd floor, 4th floor, and 7th floor, the current operating position of the car is 2nd floor, and the running direction of the car is upward, then the target floor stop results of the car can be 3rd floor, 4th floor, 5th floor, 7th floor, and 6th floor.

[0125] Among them, the 3rd, 4th, 5th and 7th floors are the level floors where the car stops when it goes up, and the 6th floor is the level floor where the car stops when it goes down.

[0126] Since the downward call command for the 11th floor is an unmarked floor, the downward call command for the 11th floor will not be responded to.

[0127] For example, the floor call instructions include the 5th floor up call instruction, the 6th floor up call instruction, and the 11th floor down call instruction; the preset operation mode is single elevator operation; the floors are 1-15, and the calibrated floor list includes 1-10 floors, that is, 11-15 floors are uncalibrated floors, the internal call instruction is the 7th floor, the current operating position of the car is the 4.5th floor, and the running direction of the car is upward, then the target floor stop results of the car can be the 6th floor, the 7th floor, and the 5th floor.

[0128] Among them, the 6th and 7th floors are the level stops when the car is currently going up, and the 5th floor is the level stop when the car goes up next time.

[0129] Since the downward call command for the 11th floor is an unmarked floor, the downward call command for the 11th floor will not be responded to.

[0130] For another example, the floor external call command is a downward external call command for the 6th floor, and the preset operation mode is single elevator operation; the current operating position of the car is the 5th floor, the running direction of the car is upward, and the internal call command includes the 3rd and 8th floors, then the target floor stop result of the car is to stop at the 8th floor for upward movement, then stop at the 6th floor for downward movement, and finally stop at the 3rd floor for downward movement.

[0131] In some embodiments, the construction elevator can be provided with two cars, a first car and a second car, and the external call box is provided with two sets of elevator call buttons, such as left elevator up and down buttons and right elevator up and down buttons. If the left elevator up and down buttons only control the left car (i.e., the first car), and the right elevator up and down buttons only control the right car (i.e., the second car), then the preset operating mode is the dual-elevator operating mode.

[0132] If the left up and down buttons can control the left car (i.e. the first car) and the right car (i.e. the second car) at the same time, and the right up and down buttons can also control the left car (i.e. the first car) and the right car (i.e. the second car) at the same time, then the preset operating mode is the parallel elevator operation mode.

[0133] When the preset operation mode is the dual-elevator operation mode, the parking control of the first car and the second car can be respectively operated according to the control logic of the single-elevator operation mode mentioned in the above embodiment, provided that the car that triggers the floor call command is determined. For details, please refer to the third embodiment of a control method for an elevator provided in the present application, and the method includes:

[0134] Step 310: Obtain the floor call instruction of the construction elevator and the preset operation mode of the construction elevator.

[0135] Step 320: Obtain the calibrated floor list of the car and the current operation information of the car.

[0136] Step 330: The first car or the second car receiving the floor call command is used as the target response car.

[0137] Step 340: Determine whether the floor number of the floor call instruction belongs to the calibrated floor list of the target response car.

[0138] For example, the calibrated floor list of the first car is 1-7 floors, and the calibrated floor list of the second car is 1-4 floors.

[0139] When the floor call command is triggered by the up and down buttons of the left elevator on the 5th floor, only the first car receives the floor call command. Therefore, the first car is the target response car. Since the 5th floor belongs to the calibrated floor list 1-7 of the first car, the first car will operate according to the control logic of the single elevator operation mode.

[0140] When the floor call command is triggered by the up and down buttons on the right elevator on the 5th floor, only the second car receives the floor call command. Therefore, the second car is the target response car. Since the 5th floor does not belong to the calibrated floor list 1-4 of the second car, the second car does not respond to the floor call command.

[0141] In some embodiments, the left and right elevator up and down buttons on the same floor can both be triggered. In this case, the first elevator car only receives the triggering instructions of the left elevator up and down buttons, and the second elevator car only receives the triggering instructions of the right elevator up and down buttons.

[0142] For example, the calibrated floor lists of the first and second elevators are both 1-7 floors. When the floor call command is that both the left elevator up button on the 5th floor and the right elevator down button on the 5th floor are triggered, the first elevator responds to the trigger command of the left elevator up button on the 5th floor, and the second elevator responds to the trigger command of the right elevator down button on the 5th floor. The first and second elevators operate according to the control logic of the single elevator operation mode respectively.

[0143] Step 350: If the floor number of the floor call instruction belongs to the calibrated floor list of the target response car, the target floor stop result of the target response car is determined based on the floor call instruction and the current operation information.

[0144] Among them, step 310, step 320, and step 350 have the same or similar technical solutions as the above embodiment, and the details can refer to the description of the relevant contents of the above embodiment.

[0145] Referring to the fourth embodiment of a control method for an elevator provided in the present application, the fourth embodiment is an operation flow when the preset operation mode is a parallel elevator operation mode, and the method includes:

[0146] Step 410: Obtain the floor call instruction of the construction elevator and the preset operation mode of the construction elevator.

[0147] Step 420: Obtain the calibrated floor list of the car and the current operation information of the car.

[0148] Step 430: Based on the floor call instruction and the preset allocation principle, determine the target response car from the first car and the second car.

[0149] For example, if the user only presses the left up button on the 5th floor, the external call button command on the 5th floor will first reach the parallel box on the first floor, which will make a judgment based on the position, running direction, fault information, etc. of the first and second cars to determine which car should be assigned to execute.

[0150] Among them, the preset allocation principles may be the nearest principle, the least number of stops principle, etc.

[0151] For example, based on the nearest principle, the car that reaches the 5th floor the fastest can be determined from the first car and the second car to respond to the 5th floor external call instruction.

[0152] Step 440: Determine whether the floor number of the floor call instruction belongs to the calibrated floor list of the target response car.

[0153] Step 450: If the floor number of the floor call instruction belongs to the calibrated floor list of the target response car, the target floor stop result of the target response car is determined based on the floor call instruction and the current operation information.

[0154] Among them, step 410, step 420, and step 450 have the same or similar technical solutions as the above embodiment, and the details can refer to the description of the relevant contents of the above embodiment.

[0155] In some implementations, the user can freely switch between the dual-elevator operation mode and the parallel-elevator operation mode according to actual needs and preferences.

[0156] Generally, in order to improve the response speed, the parallel elevator operation mode can be selected first, or the parallel elevator operation mode can be set as the default mode.

[0157] In some implementations, the user may also adjust the calibrated floor list according to actual needs, such as shielding or deleting a certain floor number, as described below:

[0158] 1) Receive a user's instruction to block, delete or restore any floor number in the calibrated floor list.

[0159] 2) Based on the shielding instruction, deletion instruction or restoration instruction, the floor number selected by the user is shielded, deleted or restored to obtain a new calibrated floor list.

[0160] After obtaining the new calibration floor list, in the above embodiment, the target floor stop result of the elevator can be determined based on the new calibration floor list.

[0161] In some implementations, the current operation information may also include the current number of people being transported. The above embodiment may further include the following steps:

[0162] Step 610: Determine whether the current number of passengers is greater than a preset standard number of passengers.

[0163] Step 620: If the current number of passengers is greater than the preset standard number of passengers, an overcrowding alarm is triggered and the construction elevator is controlled to automatically stop.

[0164] In this way, by judging whether the current number of passengers is greater than the preset standard number of passengers, a warning can be issued in time and the vehicle can be automatically shut down if there is an overload but not overweight condition.

[0165] Based on the above embodiment, it is assumed that the first controller 01 in the car has learned the floors -1 to 10 of the left and right elevators, the first-floor parallel box is installed on the -1 floor, the opening and closing of the outer door of the -1 floor is mechanically linked with the car door, the outer boxes of the 1-11 floors have been installed, and the current operation mode of the system is the parallel elevator operation mode, in which the left elevator stops at the -1 floor and the right elevator stops at the 3rd floor. The construction elevator can include the following during operation:

[0166] 1. Worker A presses the up elevator button on the first floor parallel box on the -1 floor. At this time, both up buttons on the first floor parallel box are lit, and the left elevator door opens, but the right elevator does not start.

[0167] 2. After entering the left elevator car, A presses the 5th, 7th, and 8th floor selection buttons, then the 5th, 7th, and 8th floor numbers are all lit up, and after the left elevator door closes, it starts to move upward.

[0168] 3. Worker B pressed the up button of the external call box on the 6th floor; Worker C pressed the down button of the external call box on the 6th floor; Worker D pressed the up and down buttons of the external call box on the 11th floor; the up and down buttons of the external call box on the 6th floor were all lit, but because the 11th floor was not learned and memorized and was not included in the calibrated floor list, the button on the 11th floor did not respond.

[0169] 4. After the external call command on the 6th floor is determined to be valid, it is transmitted to the first-floor parallel box through the CAN bus communication. The first-floor parallel box transmits the current status of the left and right cars to each external call box; and, after comprehensive judgment, the first-floor parallel box determines that the upward elevator call command on the 6th floor should be given to the left elevator, and the downward elevator call command should be given to the right elevator. Therefore, the command is transmitted to the internal call controller corresponding to the left and right cars, namely the second controller 02, through the wireless module.

[0170] 5. After the controller in the left car, i.e. the second controller 02, receives the upward command to the 6th floor, it determines based on calculation whether it is possible to stop at the 6th floor. If it is possible, it gives the commands for the 5th, 6th, 7th and 8th floors to the automatic leveling control part, i.e. the first controller 01 of the left car, to complete the stopping and opening and closing of the doors at the 5th, 6th, 7th and 8th floors in sequence.

[0171] The right car stops at the 3rd floor. When it receives the down command from the 6th floor, it starts to go up to pick up worker C. When the right car stops at the 6th floor, the down button on the 6th floor goes out. The car door is driven to open by the inverter in the car until the door opening limit in the limit protection interface 6 is detected to be in place. At the same time, the floor door is controlled to open by the external call box until the floor door opening limit action in the second limit detection interface 32 is detected. Then worker C walks into the right car and presses the 1st floor on the internal call floor selection button. Then the elevator in the right car completes closing the door, and the right car starts to run to the 1st floor.

[0172] During the operation of the above-mentioned construction elevator, if the floor door is accidentally opened, the external signal box can detect it and transmit it to the drive part in the car, controlling the construction elevator to stop and not restart until the abnormality is eliminated.

[0173] If there are too many people in the car, exceeding the alarm threshold, the voice module in the car can broadcast an overcrowding reminder and prohibit starting until the number of people is reduced to the allowed value.

[0174] If the inverter fails, it will shut down urgently and send out a voice announcement through the voice module. Then all internal and external call commands will be judged invalid and cleared.

[0175] If the car door and landing door are blocked by foreign objects during the closing process, the door closing action can be stopped and switched to opening action.

[0176] The present application also provides a control device for a construction elevator, which includes a unit for executing the control method for the elevator.
