Description

Elevator detection system and method thereof

Technical Field

The invention relates to the field of communication, in particular to an elevator detection system and a method thereof.

Background

In real life, the acceptance of products is an extremely critical and important step no matter which brand of elevator products. Each elevator is required to run for a period of time and for a certain number of times before being accepted, and through the simulated operation, an installer can only actually observe and collect information such as elevator running data and comfort level. It is also possible to find potential or immediately exposed problems with the elevator.

In an elevator system, the existing operation scheme is that an elevator automatically and randomly operates for a certain number of times, once the elevator operates, door opening and closing actions are carried out once after the elevator reaches a target floor, and as long as the operation times meet requirements and no fault exists, the elevator is considered to be installed completely without problems. Once the elevator generates a problem in the testing process, the detection is stopped, the problem is solved and repaired, and then the random operation detection is continued.

Specifically, in the elevator product acceptance process, the elevator car needs to be subjected to trial operation, and the elevator needs to be subjected to simulation operation, such as: controlling the lift car of the elevator to go up to a certain floor, go down to a certain floor, open and close the elevator door and the like. Meanwhile, by utilizing the operation data of the elevator observed and collected, an installer can adjust and repair the elevator in time, and the potential fault hazard of the elevator is reduced.

In the prior art, a simulation operation scheme of an elevator is to enable an elevator system to control a car to automatically and randomly operate for a certain number of times, as shown in fig. 1, the elevator system controls the car to randomly operate between a bottom layer and a top layer, wherein each time the car operates once, the elevator system randomly generates a target floor and controls the car to operate to the target floor; when the elevator car runs to a destination floor, the elevator system controls the elevator car to perform one door opening and closing action, so as to check whether the elevator has a fault; when the random operation times of the elevator car meet the requirements and no fault occurs, an installer can think that the elevator is installed completely and has no problem; and even if the car breaks down during the operation of the car, the elevator system still controls the car to execute random operation after the installation personnel stops repairing and checking.

However, the floors that are randomly operated have a certain randomness, and firstly, it cannot be guaranteed that each floor can be operated, especially on a high-floor elevator; secondly, the number of random runs can be set manually. Often, the problems of door locks, door machines, safety loops and the like generated in the early installation process of the elevator cannot be exposed by testing for several times, if the random operation times of a certain floor are too few, the probability of fault hidden danger is greatly improved, and thus certain risks are brought to acceptance and future use. Due to the randomness of the random operation detection scheme in the prior art, it cannot be guaranteed that each floor can be operated, and the number of times each floor is operated is enough, so that a new elevator detection system needs to be designed to overcome the problems.

It should be noted that the second detection module 202 may be started after the first detection module 201 is executed, or certainly, the first detection module 201 may be started after the second detection module 202 is executed, and the specific details are not limited herein. When the first detection module 201 and the second detection module 202 both complete the detection, the determination module 204 determines that the elevator system is normal, and the detection of the elevator system is complete.

In the above-described elevator detection system 200, the elevator system control car is reciprocated between the bottom floor and the top floor by the first detection module 201 and stopped when the first fault occurs, and is sequentially reciprocated between each adjacent service floor by the second detection module 202 and stopped when the second fault occurs, and the alarm module 203 may acquire and issue an alarm message when the first fault or the second fault occurs, wherein the alarm message is associated with the types of the first fault and the second fault; the determination module 204 may determine that the elevator system is normal after the first detection module 201 and the second detection module 202 are executed.

When the elevator detection system 200 is a mobile terminal, the mobile terminal includes, but is not limited to, a Personal Computer (PC), a tablet Computer, a mobile phone, and other terminals. When the elevator detection system 200 is a built-in system, the built-in system may be preset with the elevator system when the elevator leaves the factory, or may be installed in the elevator system in advance by an installer, and the built-in system may prohibit the installer from changing the built-in data parameters, which may include detection flow parameters, calculation parameters, and the like of the elevator detection system 200, and is not limited herein.

It should be noted that the elevator detection system 200 in this embodiment may also be a combination of an external system and a built-in system, and an installer may operate the external system to operate the built-in system to execute a detection process, for example: and the installer controls the built-in system installed in the elevator system through the application program installed at the mobile phone end, and controls the elevator system to execute the detection process.

As shown in fig. 3, the first detecting module 201 can specifically detect N times (N is an integer greater than 1) by controlling the car to move between the bottom floor and the top floor through the elevator system, and control the car to perform an operation of opening and closing the car door once every time the car reaches the bottom floor and every time the car reaches the top floor, wherein the car does not stop when the car is not at the bottom floor or at the top floor. Moreover, the first detection module 201 can also determine whether the elevator has a first fault through elevator operation parameters, and can stop the operation of the elevator system when the elevator has the first fault, wherein the elevator operation parameters can be obtained by sensors installed in a car, a door motor and a hoistway of the elevator and uploaded to the elevator detection system 200, and the first detection module 201 determines whether the elevator has the first fault. It should be noted that, when the elevator detection system 200 is an external system, the elevator operation parameters may also be obtained by the elevator system of the elevator and uploaded to the elevator detection system 200, which is not limited herein.

In this step, stopping the operation of the elevator system includes, but is not limited to, turning off an elevator motor to stop the operation of the car, turning off power supply to the car, and turning off power supply to the entire elevator system, and the first fault may be any one or more of an abnormality of a bottom-layer governor, an abnormality of a top-layer governor, and an abnormality of full-speed operation during the operation of the car, or an abnormality of a bottom-layer or top-layer door lock device in cooperation with a car door motor or an abnormality of a landing plate, or an abnormality of signal logic in a hoistway in which the car operates, and is not limited herein.

As shown in fig. 4, the second detecting module 202 may specifically control the car to move from the bottom floor to the service floor of the second floor through the elevator system, then move from the service floor of the second floor to the bottom floor for M times (M is an integer greater than 1), and sequentially move up layer by layer, control the car to perform detection of movement layer by layer such as detection of movement back and forth M times between the service floors of the second floor and the third floor, detection of movement back and forth M times between the service floors of the third floor and the fourth floor, and the like, where each service floor reached by the car needs to perform an operation of opening and closing the car door once. Moreover, the second detection module 202 may further determine whether the elevator has a second fault according to an elevator operation parameter, and may stop the operation of the elevator system when the elevator has the second fault, where the elevator operation parameter may be obtained by sensors installed in the car, the door motor, and the hoistway of the elevator and uploaded to the elevator detection system 200, and the second detection module 202 determines whether the elevator has the second fault. It should be noted that, when the elevator detection system 200 is an external system, the elevator operation parameters may also be obtained by the elevator system of the elevator and uploaded to the elevator detection system 200, which is not limited herein.

The stopping of the elevator system in this step also includes, but is not limited to, turning off an elevator motor to stop the car, turning off power supply to the whole elevator system, and the like, and the second failure may be any one or more of abnormality in cooperation between a service level door lock device and a car door motor, abnormality in service level flat insertion plate, abnormality in acceleration or deceleration operation of the car, abnormality in signal logic in a hoistway in which the car operates, and the specific details are not limited herein.

The alarm module 203 may specifically acquire an elevator operation parameter when the first failure occurs in the elevator or an elevator operation parameter when the second failure occurs in the elevator when the first detection module 201 determines that the elevator has the first failure or the second detection module 202 determines that the elevator has the second failure, and may obtain a failure type of the first failure (e.g., abnormal bottom speed limiting device, abnormal top speed limiting device, abnormal full-speed operation, etc.) corresponding to the elevator operation parameter when the first failure occurs, and obtain a failure type of the second failure (e.g., abnormal cooperation between a service floor door lock device and a car door motor, abnormal service floor landing insertion plate, etc.) corresponding to the elevator operation parameter when the second failure occurs, where the corresponding relationship may be preset in the elevator detection system 200. The alarm module 203 can display the correspondingly obtained fault type as warning information on a display panel, wherein if the elevator detection system 200 is an external system, such as a mobile terminal, the warning information can be displayed on the display panel of the mobile terminal; when the elevator detection system 200 is a built-in system, the warning message may be displayed on a display panel for controlling the elevator system, which is not limited herein. Thereby being convenient for the on-site personnel to troubleshoot the problem in the very first time.

It should be noted that the alarm module 203 may further obtain the failure levels of the first failure and the second failure according to the warning information, that is, the failure level corresponding to the type of the first failure may be preset in the elevator detection system 200 (for example, the failure level of the abnormal bottom speed limiting device, the abnormal top speed limiting device, and the abnormal full speed operation is the first level when the car is in operation, the failure level of the abnormal bottom or top door locking device in cooperation with a car door motor or the abnormal flat-layer inserting plate is the second level, the failure level of the abnormal signal logic in the hoistway when the car is in operation is the third level), the failure level corresponding to the type of the second failure is preset (for example, the abnormal service-layer door locking device in cooperation with a car door motor, the abnormal service-layer inserting plate is the first level, and the abnormal acceleration or deceleration operation of the car is the second level, the failure level of the logical abnormality of the signal in the shaft in which the car is running is the third level). The alarm module 203 may display the corresponding obtained failure level as warning information on a display panel, and the alarm module 203 may preferentially display the warning information of the failure type of the high level, for example: the first level of fault type is higher in priority than the second level of fault type, which is higher in priority than the third level. It is understood that the alarm module 203 may issue the warning messages in sequence according to the priority order of the fault levels, and the fault type and the fault level may also be included in the warning messages.

Optionally, in some embodiments of the present invention, the alarm module 203 may issue the alarm not only by displaying the alarm on the display panel, but also by other means, including but not limited to a vibration prompt, a voice prompt, a whistle prompt, a light flashing prompt, and the like, and the alarm module 203 may also issue the alarm in the above manner to different degrees according to different fault types or different fault levels, such as briefly whistling or flashing lights, and the like, which is not limited herein.

Preferably, in some embodiments of the present invention, as shown in fig. 5, the elevator detection system 200 may further include: the resetting module 205 is configured to restart the first detecting module 201 or the second detecting module 202 when the first fault and the second fault are repaired. Specifically, when the first fault is repaired, the reset module 205 may restart the first detection module 201, so that the elevator system controls the car to move back and forth between the bottom floor and the top floor again to perform the floor-through operation detection; or, when the second fault is repaired, the reset module 205 restarts the second detection module 202, so that the elevator system controls the car to sequentially move back and forth between each adjacent service floor to perform the detection of the floor-by-floor operation. It should be noted that, when the reset module 205 restarts the first detection module 201, the car may first run to a reset floor, which may be a bottom floor; when the reset module 205 restarts the second detection module 202, the car may be caused to resume the floor-by-floor operation detection at the current floor.

Preferably, in some embodiments of the present invention, as shown in fig. 6, the elevator detection system 200 may further include: and the first calculating module 206 is used for calculating the number of times of passing floor operation N according to the highest floor number of the elevator car operation, wherein N is an integer greater than 1, and is used for enabling the elevator system to control the elevator car to perform reciprocating operation between the bottom floor and the top floor for N times. The first calculating module 206 may calculate the number N of passing floor operations for detecting the passing floor operation according to the highest floor number of the car operation, where the number N may be equal to a constant a/the highest floor number, where the constant a may be preset in the elevator detection system 200, for example: the constant a is 1000. And when calculating the number N of the through layer operation, if the value of the obtained N is a non-integer containing decimal, the original numerical value of the N can be removed and added with 1 during calculation. In this embodiment, the highest floor number for the car to run may be called from the inside of the elevator system by the elevator detection system 200, or may be manually input by an installer, and is not limited herein.

Preferably, in some embodiments of the present invention, as shown in fig. 7, the elevator detection system 200 may further include: and the second calculating module 207 is used for calculating the layer-by-layer running times M according to the service floor number of the running of the elevator car, wherein the M is an integer larger than 1, and is used for enabling the elevator system to control the elevator car to run back and forth for M times between each two adjacent service floors. The second calculating module 207 may calculate the layer-by-layer operation frequency M detected by the layer-by-layer operation according to the service floor number of the car operation, where the service floor number is the total number of service floors serviced by the elevator, for example: in a 30-story building, 1 to 20 floors are served by one elevator, and the number of service floors in which the elevator car can operate is 20. The calculation method for calculating the layer-by-layer operation number M may be that M is a constant B/number of service floors, where the constant B may also be preset in the elevator detection system 200, for example: the constant B is 2000. And when calculating the layer-by-layer operation times M, if the obtained value of M is a non-integer containing decimal, the value of M after the decimal point of the original value can be removed and added with 1 during calculation. In this embodiment, the number of service floors in which the car operates may be called from the inside of the elevator system by the elevator detection system 200, or may be manually input by an installer, which is not limited herein. In addition, in actual calculation, the number of service floors on which the car runs can be calculated without calculating the bottom floor, for example: in a 30-storey building, a high-rise elevator reaches 1, 20 to 30 floors, and the number of service floors in which the car runs in the elevator may be counted without counting the bottom floor (1 floor), i.e., only 11 floors between 20 and 30 floors.

As shown in fig. 8, the present invention also provides an elevator detection method, which includes:

s801, enabling an elevator system to control a car to run back and forth between a bottom layer and a top layer, and stopping the elevator system when a first fault occurs;

in the step, the elevator system can control the elevator car to pass through the floor between the bottom floor and the top floor for N times (N is an integer larger than 1), and control the elevator car to perform the action of opening and closing the car door once every bottom floor is reached and every top floor is reached, wherein the elevator car does not stop at the non-bottom floor or the top floor.

In this step, the number N of passing floor operations for detecting the passing floor operation may be calculated according to the highest floor number of the car operation, where N is a constant a/highest floor number, where the constant a may be preset in the elevator detection system, for example: the constant a is 1000. And when calculating the number N of the through layer operation, if the value of the obtained N is a non-integer containing decimal, the original numerical value of the N can be removed and added with 1 during calculation.

The highest floor number of the car operation can be called from the interior of the elevator system, or can be manually input by an installer, and the operation is not limited in detail here.

It should be noted that, when the car is performing the through-floor operation detection, the elevator detection system may stop the operation of the elevator system, the first fault may be any one or more of an abnormal bottom-layer speed limiting device, an abnormal top-layer speed limiting device, and an abnormal full-speed operation, or may be an abnormal cooperation between a door lock device at the bottom layer or the top layer and a car door motor or an abnormal flat-floor inserting plate, or may be an abnormal signal logic in a hoistway where the car is operating. It should be noted that the first fault may be that the elevator operation parameter obtained by the sensor installed in the elevator car, the door motor, and the hoistway is uploaded to the elevator detection system, and the elevator detection system determines whether the elevator has the first fault, which is not limited herein.

S802, enabling the elevator system to control the elevator cars to sequentially run back and forth between each adjacent service floor, and stopping the elevator system when a second fault occurs;

in the step, the elevator system can control the car to move from the bottom layer to a service layer of a second floor, then the car moves from the service layer of the second floor to the bottom layer to detect M times (M is an integer larger than 1), and the car is controlled to move upwards layer by layer sequentially to perform layer-by-layer operation detection such as reciprocating detection M times between the service layers of the second floor and the third floor, reciprocating detection M times between the service layers of the third floor and the fourth floor, and the like, wherein each service layer reached by the car needs to perform one car door opening and closing action.

In this step, the number of layer-by-layer operation times M detected by the layer-by-layer operation can be calculated according to the number of service floors in which the car operates, which is the total number of service floors serviced by the elevator, for example: in a 30-story building, 1 to 20 floors are served by one elevator, and the number of service floors in which the elevator car can operate is 20.

The calculation method for calculating the layer-by-layer operation number M may be that M is a constant B/number of service floors, where the constant B may also be preset in the elevator detection system, for example: the constant B is 2000. And when calculating the layer-by-layer operation times M, if the obtained value of M is a non-integer containing decimal, the value of M after the decimal point of the original value can be removed and added with 1 during calculation.

The number of service floors for the car to run can be called from the interior of the elevator system by the elevator detection system, or can be manually input by an installer, and the number of service floors is not limited in detail here.

It should be noted that, when the car is performing detection of floor-by-floor operation, a second fault occurs, the elevator detection system may stop the operation of the elevator system, the second fault may be any one or more of abnormal cooperation between the service floor door lock device and the car door motor, and abnormal operation of the service floor leveling inserting plate, or abnormal operation of acceleration or deceleration of the car, or abnormal logic of a signal in a hoistway in which the car is operating. It should be noted that the second fault may be that the elevator operation parameter obtained by the sensor installed in the elevator car, the door motor, and the hoistway is uploaded to the elevator detection system, and the elevator detection system determines whether the second fault occurs in the elevator, which is not limited herein.

It should be noted that in practical applications, the number of service floors that the car travels may not be counted into the floor, for example: in a 30-storey building, a high-rise elevator reaches 1, 20 to 30 floors, and the number of service floors in which the car runs in the elevator may not count into the bottom floor (1 floor), i.e., 11 floors between 20 and 30 floors.

S803, when the first fault or the second fault occurs, acquiring and sending out warning information, wherein the warning information is associated with the types of the first fault and the second fault;

in this embodiment, when a first fault occurs during floor-passing operation or a second fault occurs during floor-by-floor operation, the elevator detection system may obtain an elevator operation parameter when the first fault or the second fault occurs in the elevator, and the elevator detection system may obtain a fault type (and a fault level) of the first fault or the second fault correspondingly, and the corresponding relationship may be preset in the elevator detection system. The elevator detection system can display the correspondingly obtained fault type (and fault grade) as warning information on a display panel, wherein if the elevator detection system is an external system of the mobile terminal, the warning information can be displayed on the display panel of the mobile terminal; when the elevator detection system is a built-in system, the warning message can be displayed on a display board for controlling the elevator system, and the details are not limited herein.

It should be noted that, when the installer repairs the first failure, the elevator system can control the car to move back and forth between the bottom floor and the top floor again to perform the floor-through operation detection, that is, step S601 is executed again; or, when the installer repairs the second failure, the elevator system control car may be caused to move back and forth between each adjacent service level in sequence to perform the detection of the layer-by-layer operation, that is, to perform step S602 again, which is not limited herein.

It should be noted that when the installer operates the elevator detection system to re-execute step 601, the car may first move to the reset floor, which may be the bottom floor; when step 602 is executed again, the car can resume the floor-by-floor operation detection at the current floor.

And S804, determining that the elevator system is normal after the elevator system controls the elevator car to run back and forth between the bottom floor and the top floor and controls the elevator car to run back and forth between each adjacent service floor in sequence.

In this step, the elevator detection system can determine that the elevator system is normal after the elevator system controls the car to move back and forth between the bottom floor and the top floor and controls the car to sequentially move back and forth between each adjacent service floor, that is, after steps S801 and S802 are completed, the elevator system can be determined to be normal, and the detection system is exited.

It should be noted that step S802 may be executed before step S801, that is, after step S802 and step S801 are executed, it may be determined that the elevator system is normal, and the present invention is not limited to this specific example.

It should be noted that, when the car performs the floor-passing operation detection or the floor-by-floor operation detection, that is, during the execution of step S801 or step S802, the installer may manually operate the elevator detection system to exit the detection, so as to stop the operation of the elevator system.
