Referring to fig. 1 of the drawings, referring to one embodiment of the present application, a method for detecting an elevator operation floor includes the steps of:

s100 detects a real-time relative distance between a current position at which the elevator is operating and a reference position provided in an elevator hoistway accommodating the elevator.

S200, analyzing floor reference information of each floor in the building where the elevator is installed, wherein the floor reference information comprises the floor relative height between two adjacent floors or the calibrated relative distance between the elevator and the reference position when the elevator is positioned on each floor.

S300, analyzing and calculating the floor reached by the elevator currently according to the floor reference information and the first relative distance between the current position and the reference position.

According to the embodiment, the current floor reached by the elevator is obtained through analysis and calculation by detecting the relative distance between the current stop position of the elevator and the preset reference position in real time and combining the floor reference information corresponding to each floor in the building. Wherein the reference position is arranged in the elevator hoistway, preferably at the top of the elevator hoistway. According to the scheme, when the stop floor of the elevator is uncertain, the current position of the elevator during running can be accurately obtained, and the detection efficiency of elevator running floor detection is improved. In addition, even when the elevator is powered off or fails, the floor where the elevator is located can be timely obtained.

In another embodiment of the present application, referring to fig. 2 of the accompanying drawings, a method for detecting an elevator operation floor includes the steps of:

s100 detects a real-time relative distance between a current position at which the elevator is operating and a reference position provided in an elevator hoistway accommodating the elevator.

S210 analyzes the floor relative height of each floor in the building where the elevator is installed.

S310 obtains a first relative distance when the elevator travels to the lowest floor of all floors when the floor relative heights of each floor are the same.

Specifically, the relative height of a floor refers to a distance between two adjacent floors, and when the relative height of each floor is a fixed value, the elevator is controlled to move to the bottommost floor of all floors, for example, the elevator is moved to a first floor, and a first relative distance between the elevator and a reference position is obtained when the elevator is at the first floor.

S320 calculates a second relative distance between the current position and the top of the elevator hoistway based on the first relative distance when the elevator is traveling to the lowest floor of all floors and the real-time relative distance between the current position and the reference position.

Specifically, according to the relative distance between the current position of the elevator and the reference position detected in real time and the first relative distance of the elevator at the bottommost layer obtained in step S310, the relative distance between the current position of the elevator and the top of the elevator shaft is calculated.

S330, analyzing and calculating the floor reached by the current running elevator according to the second relative distance and the floor relative height.

Specifically, for example, assuming that the reference position is set at the top of the elevator hoistway, when the elevator stops at any floor, the real-time relative distance between the elevator and the reference position is measured to be H, the first relative distance between the elevator and the reference position at the bottommost floor is Hmin, then the second relative distance is the absolute value of (H-Hmin), ho is the relative height of the floor, and then the floor n= (H-Hmin)/ho+1 corresponding to the current position where the elevator operates.

In this embodiment, a specific manner of calculating the elevator operation floor by using the floor relative height and the second relative distance is further described, and when the floor relative distances between any two adjacent floors are the same, the specific floor where the elevator stops can be accurately calculated.

In one embodiment, based on the above embodiment, step S210 includes: when the floor relative heights of all floors are the same, respectively acquiring first relative distances when the elevator runs to the bottommost layer and the highest layer in all floors; and calculating the floor relative height of each floor according to the total number of floors and the first relative distance when the elevator runs to the bottommost floor and the highest floor in all floors.

Specifically, when the floor spacing between two adjacent floors is the same, the elevators are operated to the bottommost floor and the highest floor of all floors in the building, and when the elevators respectively rest on the bottommost floor and the highest floor, the distance between the position and the reference position is obtained, and the relative height of the fixed floors of each floor is calculated according to the total number of the floors. For example, if the first relative distance of the bottommost layer is Hmin, the relative distance of the topmost layer is Hmax, and the total number of floors is n, the floor height Ho of each floor is = (Hmax-Hmin)/(n-1). In this embodiment, when the building pitches are the same, the relative height of each floor can be calculated by only acquiring the relative distance between the elevator and the reference position and the total number of floors when the elevator is at the bottommost floor and the highest floor.

Referring to fig. 3 of the drawings, referring to one embodiment of the present application, a method for detecting an elevator operation floor includes the steps of:

S210, when the relative heights of the floors of each floor are different, and the elevator runs to each floor, acquiring the calibrated relative distance corresponding to the current stop floor of the elevator.

S220, storing the calibrated relative distance and the floor corresponding to the calibrated relative distance in a database.

Specifically, when the relative height of the floors is not a fixed value, the elevator is controlled to run to each floor, when the elevator is stopped at different positions, the floor at the time of stopping and the corresponding calibration relative distance of the floor are recorded at the same time, and the calibration relative distance and the corresponding floor are stored in a database. The nominal relative distance of the elevator stopping floors is a real-time measured nominal distance value between the elevator and a reference position when the elevator stops at a certain floor.

S340, inquiring the calibrated relative distance matched with the real-time relative distance in the database.

Specifically, when the elevator is traveling to a certain location, a calibrated relative distance value matching the real-time relative distance of the elevator at the location is queried in the existing database. In order to improve the accuracy of detection, an error range can be preset during inquiry, and considering that the distance between two floors is generally more than 3 meters, the error range of inquiry is preferably set to plus or minus one meter.

S350, determining the floor corresponding to the target relative distance in the database as the floor corresponding to the current position.

In this embodiment, the content of analyzing the floor reference information and analyzing the floor to obtain the elevator stop floor is further described with respect to the case that the floor is not fixed in relative height. Through the calibration method, the elevator is controlled to stop at each floor, the stop floors and the corresponding calibration relative distances are recorded at the same time, and the recorded data are stored in the database, so that the data in the database can be directly called to acquire floor information when the elevator operation floors are detected later.

An embodiment of the present application further includes, after obtaining the first relative distance between the current position and the reference position where the elevator is located during operation based on any one of the above method embodiments: when the elevator runs to the next position, acquiring a first relative distance of the elevator at the next position; and comparing the first relative distance of the current position with the first relative distance of the next position, and judging the running direction of the elevator.

Specifically, according to the first relative distance detected in real time when the elevator runs to different positions, the distances obtained in two times are compared, and the running direction of the elevator is judged. For example, when the reference position is set at the top of the elevator shaft, the real-time relative distance between two stops of the elevator is differed, and if the difference is smaller than zero, the running direction of the elevator is upward; if the difference is greater than zero, the elevator running direction is descending. According to the embodiment, the real-time relative distance value measured by the elevator at two different stopping positions is compared, so that the running direction of the elevator is conveniently, accurately and rapidly obtained.
