Referring to fig. 3, the present invention proposes a first embodiment of a method for detecting an elevator unevenness, which is applied to a device for detecting an elevator unevenness, and in the first embodiment, the method for detecting an elevator unevenness includes the following steps:

and S400, outputting feedback information of the uneven layer state when the flat layer maintaining precision is larger than a preset threshold value.
Generally, an elevator includes an electrical control system, a traction system, a car system, a guide system, a weight balance system, and the like. The traction system comprises a traction motor, a traction wheel and a steel wire rope, the lift car is suspended in a well through the steel wire rope, the traction motor drives the traction wheel to rotate, and the lift car is enabled to move along the well in a lifting mode through friction between the steel wire rope and the traction wheel. When the car is located in the floor door opening area, the traction motor stops rotating, meanwhile, a brake on the traction system is in a closed state, the traction wheel is braked and locked, the traction system stops running, the car is stationary at the moment, and the car door is opened, so that passengers can get in and out. When the car needs to move, the traction motor starts to work, and meanwhile, the brake releases the traction wheel, so that the car can move up and down. Wherein, the electric control system controls the lifting and the standstill of the elevator according to a preset running curve.
In the technical scheme of the invention, the angle sensor is arranged on the shaft of the traction motor and is used for detecting the rotation information of the traction motor. As shown in fig. 2, the first position sensor 31 and the second position sensor 32 are sequentially disposed above the car 20 from top to bottom, a vertically extending support rod 40 may be disposed at the top end of the car 20, and the first position sensor 31 and the second position sensor 32 are fixed on the support rod 40. The upper part of the inner wall of the hoistway 10 corresponding to the door zone of each floor is correspondingly provided with a magnetic isolation plate 50 for triggering the first position sensor 31 and the second position sensor 32 to generate induction signals, the coverage area of the magnetic isolation plate 50 is larger than the interval between the first position sensor 31 and the second position sensor 32, and the first position sensor 31 and the second position sensor 32 can output induction signals when entering the magnetic isolation area of the magnetic isolation plate 50.
In this embodiment, when the car is stationary on a floor and the car door of the car is aligned with the landing door of the floor (i.e., the height between the car door sill and the landing door sill is equal to each other, and the height difference between the two is 0), the midpoint between the first position sensor and the second position sensor is aligned with the midpoint between the upper edge and the lower edge of the magnetic shield. Therefore, the detection of the positional deviation between the car door of the car and the landing door of the floor (i.e., the difference in height between the car door sill and the landing door sill) can be converted into the detection of the deviation of the midpoint position between the first position sensor and the second position sensor from the midpoint position between the upper side and the lower side of the magnetic shield, in other words, by comparing the deviation distances of the midpoint position between the first position sensor and the second position sensor from the midpoint position between the upper side and the lower side of the magnetic shield, the positional deviation distance between the car door of the car and the landing door of the floor can be determined.
Specifically, the first position sensor and the second position sensor may be photoelectric sensors, and taking the first position sensor as an example, the first position sensor includes a transmitting end and a receiving end that are disposed in the same direction, and the transmitting end and the receiving end face one side of an inner wall where a magnetic isolation plate of a hoistway is located, when the first position sensor enters a magnetic isolation region of the magnetic isolation plate, light emitted by the transmitting end of the first position sensor can be received by the receiving end after being reflected by the magnetic isolation plate, so that the first position sensor outputs an induction signal.
When the elevator is in the up-going state, the second position sensor positioned below is used as the target position sensor, whereas when the elevator is in the down-going state, the first position sensor positioned above is used as the target position sensor. For clarity, the following description will be given by taking the elevator upstream as a specific application scenario. The method for detecting the elevator descending is similar to that for detecting the elevator ascending, and is not repeated.
Referring to fig. 2, the second position sensor 32 is used as a target position sensor when the elevator is traveling upward. When the car 20 enters the floor door zone, the second position sensor 32 enters the magnetism isolating area of the magnetism isolating plate 50, the second position sensor 32 generates induction signals and outputs the induction signals to the processor, at the moment, the position of the car 20 is H1, signals of the angle sensors are counted, after the elevator stops completely, the moving amount of the entering level layer of the car 20 can be converted into L according to the angle change amount detected by the angle sensors, and therefore the stopping position H2=H2+L of the car 20 can be calculated; from the flat bed position H and the car 20 position H2, the flat bed holding accuracy Δ= |h-H2| of the car 20 is calculated. If the leveling maintenance accuracy delta of the car 20 is greater than a preset threshold (for example, 10 mm), judging that the car 20 is in an uneven state, and outputting feedback information at the moment; if the floor-holding accuracy delta of the car 20 is less than or equal to a preset threshold (e.g., 10 mm), the car 20 is judged to be in a normal state.
Here, the height of the middle point between the upper side and the lower side of the magnetic shield is used as the flat layer height, and the height of the middle point between the first position sensor and the second position sensor is used as the height of the car, when the car stops at the door zone, the signal of the angle sensor starts to be counted when the second position sensor enters the magnetic shield area of the magnetic shield, so that half of the length of the magnetic shield can be directly substituted into the flat layer height H, and half of the distance between the first position sensor and the second position sensor can be substituted into the height H1 of the car. The length of the magnetic isolation plate refers to the length of the magnetic isolation plate along the vertical direction, namely the distance between the upper edge and the lower edge of the magnetic isolation plate.
According to the detection method of the technical scheme, the deviation position of the elevator car relative to the landing door zone when entering a landing, namely the height difference between the elevator car door sill and the landing door sill, can be accurately detected, so that the elevator non-landing state can be accurately detected, feedback information is output when the elevator is in a non-landing state, passengers are reminded of paying attention to safety, and maintenance staff is informed of timely maintenance, so that the elevator safety is improved.
Further, referring to fig. 4, the present invention proposes a second embodiment of a method for detecting an elevator unevenness layer, based on the first embodiment, the step S200 includes:
s210, acquiring the accumulated pulse number of the angle sensor when the target position sensor generates a sensing signal to the angle sensor stops rotating;
s220, calculating the angle change amount according to the pulse number of the angle sensor in the unit circumference and the accumulated pulse number.
In this embodiment, the target position sensor outputs an induction signal when entering the magnetism isolating region of the magnetism isolating plate, and at this time, the pulse number of the angle sensor starts to be counted. The angle sensor is an element for converting angle information into corresponding electric signals to be output. The angle sensor, i.e., the rotary encoder, has gratings arranged in the circumferential direction mounted on a shaft inside, and the gratings are cut by rotation of the shaft. For example, if the angle sensor is a 360-pulse product, then each turn outputs 360 pulses, one pulse represents 1 °, and for example, if the angle sensor is a 60-pulse product, then each turn outputs 60 pulses, then one pulse represents 6 °. That is, the number of pulses per unit circumference of the angle sensor can be used to determine the angle represented by one pulse of the angle sensor, and when the target position sensor enters the magnetism isolating region of the magnetism isolating plate and the target position sensor is stationary, the angle sensor detects the number of accumulated pulses multiplied by the angle represented by one pulse, thereby obtaining the angle change amount.
Further, referring to fig. 5, the present invention proposes a third embodiment of a method for detecting an elevator unevenness layer, based on the first embodiment, the step S300 includes:
s310, calculating the leveling layer entering movement amount of the elevator according to the angle change amount, wherein the leveling layer entering movement amount is the movement distance of the target position sensor from entering the magnetism isolating area of the magnetism isolating plate to stopping;
s320, calculating the flat layer maintaining precision according to the first length, the second length and the flat layer entering movement amount.
In this embodiment, when the angle change amount of the angle sensor is obtained, the amount of the elevator moving into the leveling layer can be determined according to the association relationship between the detected angle of the angle sensor and the elevator lifting distance, so as to determine the elevator stopping position, and finally calculate the leveling layer holding precision of the car. The deviation position of the elevator car relative to the leveling door zone when entering the leveling layer can be judged by comparing the leveling layer holding precision of the elevator car with the preset threshold value, namely, the height difference between the elevator door sill and the landing door sill, so that the accurate detection of the uneven elevator state is realized, and the elevator safety is improved.
Further, referring to fig. 6, the present invention proposes a fourth embodiment of a method for detecting an elevator unevenness layer, based on the third embodiment, the step S320 includes:
s321, determining a mapping relation between an angle and a distance according to the perimeter of a traction sheave of the elevator and the pulse number of the angle sensor of the traction sheave in unit turns;
s322, determining the leveling layer moving amount of the elevator according to the mapping relation between the angle and the distance and the angle change amount.
In this embodiment, when the amount of movement of the elevator into the leveling floor is converted according to the amount of change in the angle of the angle sensor, it is necessary to determine the correlation between the detected angle of the angle sensor and the lifting distance of the elevator, and in the course of one rotation of the angle sensor with the shaft of the traction motor, the lifting distance of the elevator is determined by the circumference of the traction sheave, so it is necessary to determine the mapping between the detected angle of the angle sensor and the circumference of the traction sheave. Specifically, if the angle sensor is a 60-pulse product, each circle outputs 60 pulses, one pulse represents 6 °, and if the traction sheave rotates one circle, the lifting distance of the elevator is 60mm (i.e., the circumference of the traction sheave is 60 mm), and the mapping relationship between the angle and the distance is 1 ° and corresponds to 10mm. After the mapping relation between the angle and the distance is determined, when the angle change amount of the angle sensor is obtained, the level-entering layer moving amount of the elevator can be converted according to the mapping relation between the angle and the distance.
Further, referring to fig. 7, the present invention proposes a fifth embodiment of a method for detecting an elevator unevenness layer, based on the first embodiment, before the step S100, further comprising:
s500, identifying the running direction of the elevator according to the positive and negative of the angle change quantity of the angle sensor, wherein the running direction comprises one of ascending and descending.
In this embodiment, when determining the first position sensor or the second position sensor as the target position sensor, it is necessary to determine the running direction of the elevator, that is, the elevator up or down, and the running direction of the elevator may be determined by detecting the forward rotation or reverse rotation of the traction motor by the angle sensor.
Further, referring to fig. 8, the present invention proposes a sixth embodiment of a method for detecting an elevator unevenness layer, based on the first embodiment, the step S100 includes:
s110, determining the first position sensor as the target position sensor when the running direction is downward, wherein the first position sensor is positioned above the second position sensor;
and S120, determining the second position sensor as the target position sensor when the running direction is upward.
In this embodiment, since the position deviation distance between the car door of the car and the landing door of the floor is determined by comparing the deviation distance between the midpoint position between the first position sensor and the second position sensor and the midpoint position between the upper edge and the lower edge of the magnetic shield, the first position sensor is used as the target position sensor when the elevator is descending, and the signal of the angle sensor is counted when the first position sensor enters the magnetic shield area of the magnetic shield; on the contrary, when the elevator goes up, the second position sensor is taken as the target position sensor, and when the second position sensor enters the magnetism isolating area of the magnetism isolating plate, the signals of the angle sensor are counted.
Further, referring to fig. 9, the present invention proposes a seventh embodiment of a method for detecting an elevator unevenness layer, based on the first embodiment, the step S400 further includes:
and S600, controlling the elevator to stop running.
In the normal course of ascending, when the second position sensor enters the magnetism isolating area of the magnetism isolating plate, the car is about to enter the flat landing door area, at the moment, a brake on the traction system is required to be closed, and the band-type brake is implemented to stop so that the car accurately stops at the flat landing door area. If the flat layer keeping precision of the lift car is larger than a preset threshold value, slip is possibly generated between the traction sheave of the host machine and the steel wire rope, or an error occurs in the operation of the band-type brake, and at the moment, the lift has potential safety hazards and is not suitable for continuous operation and use. Therefore, when the uneven floor state of the elevator car is detected, the traction motor should be controlled to stop working, so that the elevator is stopped, and after maintenance personnel confirms the fault and maintains the problem, the elevator is opened for use.
Further, the invention provides an eighth embodiment of the method for detecting an elevator uneven floor, and based on the first embodiment, the feedback information of the uneven floor state comprises alarm information and/or maintenance prompt information.
In this embodiment, the car of the elevator is further provided with a voice stop-reporting device, when the elevator is detected to be in an uneven state by the method, voice alarm information can be given to passengers through the voice stop-reporting device to remind the passengers to prevent the passengers from tripping, and meanwhile, the processor is also in wireless communication with the terminal equipment through the wireless communication module, so that relevant elevator state information can be pushed to relevant personnel, such as maintenance personnel, so that the maintenance personnel can obtain the information in time, and maintain the elevator as soon as possible, thereby being beneficial to improving the safety of the elevator.
In order to achieve the above object, the present invention also provides a device for detecting an elevator unevenness layer, the device comprising: the method for detecting an elevator car according to any of the above embodiments comprises the steps of a first position sensor, a second position sensor, an angle sensor, a memory, a processor and a detection program for an elevator car stored on the memory and operable on the processor, which when executed by the processor, realizes the method for detecting an elevator car.
In order to achieve the above object, the present invention also provides a storage medium having stored thereon a detection program of an elevator unevenness, which when executed by a processor, implements the steps of the detection method of an elevator unevenness of any one of the above embodiments.
