Example 1
In an embodiment of the application, a method for acquiring the stop floors of an elevator car in real time is provided, and is used for acquiring the floor change of the elevator car when the elevator car runs in an elevator hoistway in real time, so that the accuracy of judging the floor information change is improved.
As shown in fig. 1, the method of acquiring the stop floor of the elevator car in real time includes the following steps S101-S105.
Step S101, recording a first moment and a second moment which are triggered by the same object and correspond to a first sensor and a second sensor, wherein the first sensor is arranged below the second sensor;
as an example, the first sensor and the second sensor are the same type of sensor; wherein the same type refers to the same implementation principle of the sensor.
When the method is implemented, a first sensor and a second sensor mounted on an elevator car are triggered when passing through a magnetic isolation plate in a hoistway respectively, a triggering time point of the first sensor is defined as a first moment, and a triggering time point of the second sensor is defined as a second moment; wherein, the first sensor is arranged below the second sensor at intervals along the vertical direction, in some embodiments, the first sensor is arranged below the second sensor, and the lower part in the above description refers to that two sensors are arranged at a certain interval.
In this step, when the elevator car is running, the first and second sensors on the sensor module are triggered by the magnetic separator as the car moves past the magnetic separator of the hoistway to generate a signal. And each floor of the hoistway is provided with a magnetic shield, the first sensor and the second sensor are triggered once as the car moves through each floor, i.e., the first sensor and the second sensor are triggered once respectively as the car moves through each floor. When the sensor runs in the well for the first time, the elevator car is operated to the bottommost layer of the well for manual calibration, so that the detection precision is ensured.
As an embodiment, the first sensor and the second sensor adopt infrared sensors, and the two infrared sensors have two probes, one probe is used for sending signals, and the other probe is used for receiving signals; the first sensor and the second sensor can be arranged on an elevator car or in an elevator hoistway, and when two probes on the first sensor or the second sensor are triggered by the same plate (usually a magnetic isolation plate is selected), the triggered moment is recorded; when the infrared sensor is arranged on the elevator car, the infrared sensor can be triggered by the magnetic isolation plate in the hoistway, and when the infrared sensor is arranged in the hoistway, the infrared sensor can be triggered by the same object, part or the same position on the elevator car.
As an example, the first sensor and/or the second sensor may be magnetic sensors, and the triggering is induced by correspondingly arranged magnets or magnetic fields, and the moment when the magnetic sensors are triggered and the movement direction of the elevator car are obtained by referring to the implementation method.
As an example, the infrared sensor may also be an ultrasonic sensor, and when an ultrasonic sensor is used, the arrangement and the implementation thereof are the same as those of the infrared sensor.
As an embodiment, the first sensor and/or the second sensor may alternatively use an NFC tag, and the movement direction and the trigger time of the elevator car are obtained through induction triggering of the NFC tag.
The first sensor and the second sensor can also adopt other known sensor forms, the arrangement form of which is not limited by the embodiment, as long as the first sensor and the second sensor can be triggered by the same object and acquire the triggered moment so as to judge the movement direction of the elevator car according to the trigger moment.
As an embodiment, the first sensor and the second sensor are one or any two of an infrared sensor, an ultrasonic sensor, a magnetic sensor and an NFC tag, for example, the first sensor is an infrared sensor or an ultrasonic sensor, and the second sensor is a magnetic sensor or an NFC tag.
Step S102, judging the sequence of the first moment and the second moment and calculating the time interval between the first moment and the second moment.
Wherein, there are two cases in the time interval of the first moment and the second moment: one is the time interval when passing through the magnetic insulation plates of the same floor, respectively, and typically such time interval is shorter; the other is the time interval in which one sensor is triggered separately from the other sensor after crossing the floor, which is longer because of the need to cross the floor.
Step S103, if the first moment is earlier than the second moment and the time interval is within a preset duration interval, the first sensor is triggered first and is positioned in front of the running direction of the car; and because the time interval between the first sensor and the second sensor is triggered in a preset time interval, the first moment and the second moment are triggered by the same magnetic isolation plate successively, and the situation of cross-floor triggering and the situation of slight shaking of the car are eliminated. Therefore, at this time, it is judged that the elevator car moves downward once, and the number of the current stop floors is decreased by one. Similarly, if the first moment is later than the second moment and the time interval is within a preset duration interval, the elevator car is judged to move upwards once, and the number of the current stopping floors is increased by one. In this embodiment, the preset duration interval is greater than 5ms and less than 100ms, and this duration interval may be preset according to the actual situations of the moving speed of the elevator, the distance set by the first sensor and the second sensor, and the like.
In some embodiments, the elevator may take any floor as the initial floor while running, and then update the floor change on the initial floor information.
In other embodiments, the elevator may reach a particular floor, such as the bottommost floor, at the beginning of its travel and update the floor change based on the particular floor information.
Therefore, the steps S101-S103 can determine the up-down status of the elevator and the corresponding floor change information based on the detection information of the first sensor and the second sensor on the basis of the initial floor information. Considering that the infrared of the infrared sensor is invisible light, but is also influenced by external environment, and the magnetic sensor, the NFC label and the like are easily interfered by environmental signals, so that the judgment result is inaccurate, and an air pressure detection device such as an air pressure gauge and the like is needed to be matched for auxiliary judgment.
Step S104, when the first sensor and the second sensor are triggered and the time interval is within a preset time interval, recording the current air pressure value of the elevator car.
In this step, the difference in height of the elevator car above and below the physical space corresponds to different air pressure values, and the current air pressure value of the elevator car is recorded each time an event is encountered in which the first sensor and the second sensor are effectively triggered.
Step S105, comparing the current air pressure value with the current air pressure value recorded last time, namely comparing the air pressure value obtained by each measurement with the air pressure value obtained by last measurement, generally determining that the difference operation is invalid after the current air pressure value is recorded second time, if the absolute value of the obtained air pressure difference is lower than a preset air pressure threshold (in the embodiment, the air pressure threshold between two floors is set to be 5Pa and is matched with the air pressure value variation of one floor, if the difference between the two air pressure values is about 2Pa, indicating that the elevator car does not run to the next floor, determining that the current sensor is triggered possibly by false triggering at the moment, and correspondingly confirming the number of stopping floors of the elevator car, thereby finally improving the accuracy of judging the floor variation of the elevator.
Further, in one embodiment, the method further comprises the steps of: and sending the acquired floor information of the elevator car to the robot and/or the cloud in real time. Specifically, after the elevator acquires the elevator car floor information in real time, the elevator can be transmitted to the robot and/or the cloud end in real time through the 4G signal, and the robot is helped to carry out operations such as elevator taking.
In the above embodiment, the confirmation of the number of floors at which the elevator car stops includes the following implementation forms or confirmation modes:
first, when detecting through the sensor that elevator floor changes, will be elevator floor information record, wait to confirm effective back through atmospheric pressure detection, send new floor information to robot and/or high in the clouds again.
In the second mode, when the sensor detects that the elevator floor changes, the air pressure value is recorded at the same time, and when the floor information change condition is met, the floor information is updated and sent to the robot and/or the cloud.
As an example, the steps S102 to S104 are not consecutive.
As an example, the current air pressure value may be detected by an air pressure detecting device or module, which may employ an air pressure gauge or an air pressure sensor.
As an embodiment, a one-to-one mapping relation table is constructed between the air pressure values of the corresponding floors, the mapping relation table can be dynamically updated in real time, the air pressure values of the corresponding floors can be obtained through the mapping relation table, the air pressure values corresponding to different floors are different, namely, the air pressure values of the corresponding floors and the air pressure values of the corresponding floors are in one-to-one mapping relation, and whether the current floor change is reliable or not is judged based on an air pressure threshold.
Example two
