Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The elevator data processing method provided by the application can be applied to the application environment shown in figure 1. The application environment includes a target elevator 102, sensors within the target elevator, and a server 104. The target elevator 102 and the sensor can communicate with each other in a wired or wireless manner, and the sensor is used for collecting operation data of the target elevator 102. The target elevator 102 communicates with the server 104 over the network through internal sensors over the network. The sensors may send the collected data to the server 104.
Specifically, the sensor can acquire the current operation data of the target elevator 102 in real time, and add a timestamp to the operation data through the communication module of the sensor to mark the acquisition time of the operation data. The sensors then send the collected operational data to the server 104. The server 104 can receive the operational data of the target elevator 102 sent by the sensors and can store the operational data. The server 104 obtains a current operation data set corresponding to the target elevator, associates current operation data in the current operation data set according to a time stamp of the operation data in the current operation data set, and determines a target operation associated data set corresponding to the current operation data set. The server 104 may generate an uplink operation curve and a downlink operation curve of the target elevator according to the target operation related data set, determine a balance coefficient of the target elevator according to the uplink operation curve and the downlink operation curve, and determine a current operation state of the target elevator according to the balance coefficient. Wherein the target elevator 102 can be one elevator or a plurality of elevators. The sensors may be multiple, including various types of sensors, such as current sensors, voltage sensors, laser ranging sensors, etc., and the server 104 may be implemented as a stand-alone server or a server cluster composed of multiple servers.
The balance coefficient of the elevator is determined by recording the current value of the motor when the car and the counterweight move to the same horizontal position, and drawing a current-load rate curve and determining the intersection point of the upper operation curve and the lower operation curve.
In one embodiment, as shown in fig. 2, an elevator data processing method is provided, which is described by taking the example that the method is applied to the server in fig. 1, and comprises the following steps:
s202, acquiring a current operation data set corresponding to the target elevator, wherein the current operation data in the current operation data set carries a timestamp, and the timestamp is added through a communication module of a sensor corresponding to the target elevator.
Wherein the target elevator is an elevator installation which needs to detect the balance factor. For example, the target elevator may be a passenger elevator, a cargo elevator, a construction elevator, and the like. The current operation data refers to data generated when the elevator operates in the current time period, and includes the operation distance, the operation current and the operation voltage of the elevator. The current running data set refers to a set composed of current running data, and the running data in the current running data set may be ordered or unordered, for example, may be ordered according to time. The current time period refers to a time period in which the current time is. The time length of the time period of the current time can be set according to needs, for example, the current-day operation data of the target elevator can be obtained to form a current-day operation data set. The balancing coefficient of the elevator is detected from the current day running data set.
The travel distance of an elevator can be expressed in terms of the distance of the top of the elevator car from the top of the hoistway. The distance between the top of the elevator car and the top of the shaft can be detected by a laser ranging sensor placed on the top of the elevator car. The running current of the elevator is the current passing through a traction machine motor when the elevator runs and can be detected by a current sensor. For example, the operating current of an elevator is detected by clamping a current sensor to one of the input phases of the elevator machine motor. The operation voltage of the elevator is the output voltage of the weighing sensor when the elevator operates, and can be detected by the voltage sensor connected with the elevator weighing sensor. Because the weighing sensor outputs voltage, the voltage sensor detects the output voltage of the weighing sensor, and the actual load of the elevator can be calculated according to the detected output voltage. The calculation formula is as follows: g ═ k × U. Wherein, G represents the actual load of elevator, and U represents the operating voltage of elevator, and k is the constant, can carry out the custom setting according to different elevators. The load factor of the elevator can be calculated according to the actual load of the elevator and the rated load of the elevator.
The time stamp is a character string consisting of two characters of numbers and symbols and is used for uniquely identifying the receiving time of the data sent by the acquisition module received by the communication module of the sensor.
The current operating data includes data collected by a plurality of sensors. Because, the collection module of sensor is when gathering data, can not record corresponding time stamp. If the time of the data arriving at the server is taken as the data acquisition time, the data arriving at the server from different communication modules will pass through different computer nodes, so the time of the data arriving at the server is taken as the data acquisition time, and the data acquired by a plurality of sensors at the same time cannot be accurately identified. Therefore, the communication module of the sensor adds a time stamp to the collected data. In one embodiment, a plurality of sensors that the target elevator corresponds all are the loRa sensor, and the time that the collection module of loRa sensor will gather data transmission to communication module is fixed, consequently can accurately discern the collection time that the sensor gathered data according to the time stamp.
In one embodiment, the timing of the communication modules of each sensor is time synchronized with the server, ensuring that the communication modules of each sensor are on the same time reference when the time stamp is added.
Specifically, the server obtains a current operation data set corresponding to the current time period of the target elevator from the database.
In one embodiment, the server may receive an elevator detection request carrying an electronic device identification of a target elevator. And then, the server acquires a current operation data set corresponding to the current time period of the target elevator according to the elevator detection request.
In one embodiment, the electronic device identification and the sensor identification are stored in association in a database of the server. Therefore, the sensor identifier corresponding to the electronic equipment identifier can be found according to the electronic equipment identifier of the target elevator. And then the operating data corresponding to the sensor identifier can be found according to the sensor identifier.
And S204, associating the current operation data in the current operation data set according to the time stamp to obtain a target operation associated data set corresponding to the current operation data set.
Specifically, the current operation data set includes multiple types of current operation data at multiple times, and the various types of current operation data are detected by different sensors, so that the current operation data with the same timestamp needs to be subjected to data association according to the timestamp of the current operation data, and a target operation associated data set corresponding to the current operation data set is obtained. The target operation associated data set comprises operation associated data sets corresponding to a plurality of different timestamps. The operation-related data set corresponding to a time stamp includes various current operation data corresponding to the time stamp, and it is understood that the various current operation data are collected by a plurality of sensors at the same time.
In one embodiment, the current operating data includes operating distance, operating current, and operating voltage. The current operating data set includes operating distances, operating currents, and operating voltages for a plurality of times. When the counterweight of the target elevator is at the same level with the car, the distance L between the top of the car and the top of the shaft can be obtained through the historical test data of the target elevator0. When the traveling distance L of the target elevatortIs equal to L0Is shown at running distance LtAt the corresponding point in time, the counterweight of the target elevator is at the same level as the car. According to the travel distance LtTime stamp of (2), time stamp and travel distance LtThe operating current and the operating voltage with the same timestamp are correlated to obtain an operating correlation data set. The running distance corresponding to a plurality of times in the current running data set is equal to L0Thus, multiple sets of operational association data may be obtained. Further, the operational data in the current operational data set may be sorted by time. Suppose LtData of previous time point is Lt-1The data at the latter time point is Lt+1. When L ist+1-Lt-1>And when 0, the target elevator runs downwards and is in a descending state. When L ist+1-Lt-1>And when 0, the target elevator runs upwards and is in an ascending state. Therefore, the up-down running state of the elevator can be judged according to the running distance. Further, it may be determined whether the operating current in the set of operating related data is an up current or a down current. The up current is the corresponding running current when the target elevator is in an up state. The descending current refers to the current corresponding to the target elevator in the descending state.
And S206, generating an ascending operation curve and a descending operation curve of the target elevator according to the target operation associated data set.
The ascending operation curve is a curve reflecting that the operation current changes along with the change of the load factor when the target elevator is in an ascending state. The downward running curve is a curve reflecting that the running current changes along with the change of the load factor when the target elevator is in a downward state.
Specifically, the target operation associated data set includes operation associated data sets corresponding to a plurality of different timestamps. The operation-related data set includes an operation current and an operation voltage. The operation related data set may be divided into an uplink operation related data set and a downlink operation related data set according to whether the operation current is an uplink current or a downlink current. The load factor of the target elevator can be calculated according to the running voltage. Therefore, the ascending running curve and the descending running curve of the target elevator can be generated according to the load factor and the running current of the target elevator corresponding to the plurality of different time stamps.
And S208, determining the balance coefficient of the target elevator according to the uplink running curve and the downlink running curve, and determining the current running state of the target elevator according to the balance coefficient.
Specifically, the server obtains coordinates corresponding to an intersection point of the uplink running curve and the downlink running curve, and determines the load rate of the target elevator corresponding to the intersection point according to the coordinates of the intersection point, wherein the load rate is the balance coefficient. And when the balance coefficient is within the preset threshold range, determining the running state of the target elevator as a safe state. And when the balance coefficient is not in the preset threshold range, determining the running state of the target elevator as an abnormal state. The preset threshold range may be set according to national standards of elevators. The national standard stipulates that the balance coefficient of the traction type elevator is within the range of 0.4-0.5. Different preset threshold ranges can also be set according to different elevator models. The specific preset threshold ranges corresponding to different elevator models can be set by the manufacturer of the elevator or by the maintainer of the elevator. When the running state of the target elevator is an abnormal state, the counterweight of the target elevator is unreasonably arranged, potential safety hazards exist, the counterweight of the target elevator is timely adjusted, and the balance coefficient of the target elevator is adjusted to be within a preset threshold range. Therefore, when the running state of the target elevator is an abnormal state, the server can generate alarm information according to the electronic equipment identifier of the target elevator and send the alarm information to the preset terminal. And after receiving the alarm information, the preset terminal displays the electronic equipment identifier of the target elevator corresponding to the alarm information and carries out alarm prompt. The alarm prompt may be a preset prompt sound or a vibration prompt, or may be in other manners, which is not limited in this application.
In one embodiment, after the server generates the alarm information, the server can also send the alarm information to a terminal corresponding to a maintenance worker, and the terminal corresponding to the maintenance worker can display the alarm information and give an alarm prompt, so that the maintenance worker can know the abnormal condition of the elevator in time and repair the elevator.
In one embodiment, the alarm information can also comprise the geographical position information of the elevator, so that maintenance personnel can confirm the geographical position of the abnormal elevator in time to carry out emergency repair on the elevator.
In the elevator data processing method, a current operation data set corresponding to a target elevator is obtained, current operation data in the current operation data set carries a timestamp, and the timestamp is added through a communication module of a sensor corresponding to the target elevator; associating the current operating data in the current operating data set according to the timestamp to obtain a target operating associated data set corresponding to the current operating data set; generating an uplink running curve and a downlink running curve of the target elevator according to the target running associated data set; and determining the balance coefficient of the target elevator according to the uplink running curve and the downlink running curve, and determining the current running state of the target elevator according to the balance coefficient. Because the current operation data set comprises current operation data corresponding to a plurality of moments in the current time period of the target elevator, the balance coefficient of the target elevator is detected by acquiring the current operation data set of the target elevator, the real-time automatic detection of the balance coefficient of the elevator can be realized, and the detection efficiency of the balance coefficient of the elevator is improved. In addition, the timestamp of current operation data is added by the communication module of sensor, can accurately discern the operation data that a plurality of sensors gathered at same time according to the timestamp of current operation data, and then can improve elevator balance coefficient and detect the rate of accuracy.
In one embodiment, before step S202, the method further includes: receiving current operation data uploaded by a sensor corresponding to a target elevator; analyzing the current operating data to obtain a timestamp of the current operating data; and storing the current operation data into a database according to the time stamp of the current operation data.
Specifically, the server receives current operation data uploaded by a plurality of sensors corresponding to the target elevator. The current running data carries a timestamp. And the server analyzes the current operation data to obtain the time stamp of the current operation data. And then, the server stores the current operation data into the database by taking the time stamp as a key word.
In one embodiment, a plurality of sensors of the target elevator each collect operational data of the target elevator. The acquisition module of each sensor sends the operation data who gathers to the communication module of each sensor. And the communication module of each sensor adds a time stamp to the operation data by using the receiving time of the operation data. And then, the communication module of each sensor passes through loRa transport protocol and sends operation data to the loRa gateway, and the loRa gateway sends current operation data to the server again. The server analyzes the received operation data, extracts the time stamp of the operation data, and then stores the operation data into the database by taking the time stamp as a keyword. The LoRa transmission protocol is a low-power-consumption wireless transmission protocol suitable for the Internet of things.
In one embodiment, to improve the security and reliability of data, the LoRa transport protocol provides data encryption services. The communication module of sensor sends the operation data to the loRa gateway after encrypting and encoding. And the LoRa gateway decodes and decrypts the received operation data and then sends the operation data to the server.
In one embodiment, the sensor and server may also agree on a key for encryption and decryption. The communication module of sensor sends the operation data to the loRa gateway after encrypting and encoding. And the LoRa gateway sends the operation data to the server, and the server decodes the operation data and then decrypts the operation data based on the appointed decryption key.
In the embodiment, the current operation data uploaded by the sensor corresponding to the target elevator is received; analyzing the current operating data to obtain a timestamp of the current operating data; and storing the current operation data into a database according to the time stamp of the current operation data. Therefore, the database stores the corresponding relation between the current operation data and the timestamp of the current operation data, and the corresponding operation data can be conveniently and quickly found according to the timestamp.
As shown in fig. 3, in an embodiment, the current operation data includes an operation voltage, an operation current, and an operation distance, and the step S204 specifically includes:
s302, acquiring a running distance.
S304, when the running distance is equal to the distance threshold value, determining that the running distance is the target distance.
The distance threshold value is the distance between the top of the car and the top of the shaft when the counterweight of the target elevator and the car are at the same horizontal position.
Specifically, the current run data set includes a plurality of run distances. When the travel distance is equal to the distance threshold, the travel distance is taken as the target distance.
S306, determining a target operation associated data set according to the time stamp of the target distance.
The server acquires a timestamp of the target distance; acquiring a timestamp of the operating voltage and a timestamp of the operating current; the operating voltage and the operating current with the same timestamp as the target distance are taken as operating associated data and are classified into the same operating associated data set, so that a plurality of operating associated data sets corresponding to different timestamps are obtained; verifying the effectiveness of each operation associated data set, and forming a target operation associated data set by the verified operation associated data sets.
Specifically, the current operation data set comprises operation data of multiple up-and-down operations of the target elevator in the current time period, so that multiple target distances can be determined according to the operation distances in the current operation data set, and the time stamps of the target distances are different. According to the time stamp of a target distance, the operating voltage and the operating current with the same time stamp as the time stamp of the target distance can be used as the operating associated data to form an operating associated data set. That is, when the target elevator runs to a position where the counterweight and the car are at the same level, the running voltage and the running current collected at that point in time are correlated. And determining the running associated data set corresponding to the time stamp of each target distance according to the time stamp of each target distance. And the server verifies the validity of each operation associated data set and forms the verified operation associated data sets into a target operation associated data set.
