Specific embodiments of the present application have been shown by way of the above drawings and will be described in more detail below. The drawings and the written description are not intended to limit the scope of the inventive concepts in any way, but rather to illustrate the inventive concepts to those skilled in the art by reference to the specific embodiments.
Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
A large number of electronic devices (e.g., sensing devices and executing devices, etc.) are typically deployed in a factory. At least one signal point may be provided on one electronic device. For example, an electronic device including a motor is taken as an example, and a sensing device for detecting the rotation speed of the motor, an executing device for controlling the rotation speed of the motor, and the like of the electronic device are all signal points of the electronic device.
In a factory digital scene, in order to realize unified monitoring of the electronic equipment, an edge computing host is connected with the electronic equipment, data acquisition is performed on signal points of the equipment, and the electronic equipment is monitored in a unified mode according to the acquired data.
Taking a signal point as a sensing device as an example, the data of the signal point may be the data (such as temperature, humidity, rotation speed, etc.) detected by the sensing device. Taking a signal point as an executing device as an example, the data of the signal point may be the data (such as a rotation speed, a voltage, a current, etc.) output by the executing device.
At present, the existing data acquisition method mainly comprises the following two steps:
1. acquiring data of signal points of each electronic device in a polling mode: the edge computing host collects signal point data in a polling mode one by one through the query command until all the signal points of the electronic equipment are obtained. When the number of signal points is small, the data acquisition can be completed quickly by the method. However, when the number of signal points is large, the data acquisition method needs to consume more time, and has low data acquisition efficiency and poor data instantaneity.
2. And simultaneously acquiring data of a plurality of signal points. And the edge computing host acquires a section of memory data with preset length of the electronic equipment when the edge computing host inquires the command. The memory data with a preset length may include data of a plurality of signal points. When the memory data with the preset length contains more data of the signal points, the data of a plurality of signal points can be acquired through a section of memory data with the preset length, and higher data acquisition efficiency can be realized. However, when the data of the signal point included in the memory data with the preset length is less, because the memory data with the preset length takes a certain time to be transmitted, the average acquisition time of each signal point data is increased, and thus the acquisition efficiency of the signal point data is reduced.
Therefore, the existing data acquisition methods have the problem of low data acquisition efficiency.
Considering the problem of low data acquisition efficiency of the existing data acquisition method, the application provides a method for predicting the time length required by data acquisition in two different data acquisition modes respectively, and then carrying out data acquisition in a data acquisition mode with short time so as to improve the data acquisition efficiency. Optionally, the execution main body of the data acquisition mode provided by the application can be any electronic device such as a terminal and a server with a processing function.
Taking the above electronic device as an edge computing host as an example, fig. 1 is a schematic view of an application scenario of the data acquisition method provided by the present application. As shown in fig. 1, the edge computing host may be connected to N target devices to collect data of signal points of the N target devices.
It should be understood that the connection manner between the edge computing host and the N devices is not limited by the present application. The edge computing host and the N devices may be connected by wireless communication, for example. The wireless communication method may be, for example, a communication method based on OPC UA communication protocol. Among them, OPC UA is generally called OLE for Process Control. OLE is known as Object Linking and Embedding. Alternatively, the wireless communication method may be, for example, a communication method based on a MODBUS communication protocol.
Further, it should be understood that the present application is not limited to the types of target devices described above, and the types of signal points (e.g., sensors or actuators, etc.) of the target devices.
The technical scheme of the present application will be described in detail with reference to specific examples. The following embodiments may be combined with each other, and some embodiments may not be repeated for the same or similar concepts or processes.
Fig. 2 is a schematic flow chart of a data acquisition method provided by the application. As shown in fig. 2, the method comprises the steps of:
s101, acquiring a target device list, time-consuming parameters of a first data acquisition mode and time-consuming parameters of a second data acquisition mode.
The target device list may include: and N identifications of target devices to be subjected to data acquisition. The N may be an integer greater than or equal to 1.
For any one of the first data acquisition mode and the second data acquisition mode, the time-consuming parameter of the data acquisition mode may be used to calculate a time length required for the electronic device to perform data acquisition on the signal points of the N target devices through the data acquisition mode. By way of example, the time-consuming parameters of the data acquisition mode may include, for example, at least one of: the method comprises the steps of transmitting a single byte between the electronic equipment and the target equipment, acquiring data of a signal point by the target equipment, analyzing the data of the target signal point from a response frame of the target equipment by the electronic equipment, and the like.
It should be appreciated that the first data acquisition mode described above may be any of the existing data acquisition modes. The second data acquisition mode may be any existing data acquisition mode different from the first data acquisition mode. Illustratively, taking the first data acquisition mode as an example of the 1 st data acquisition method described in the foregoing prior art, the second data acquisition mode may be, for example, the 2 nd data acquisition method described in the foregoing prior art.
Alternatively, as shown in fig. 1, taking an electronic device as an edge computing host, the electronic device may also be connected to the device management platform, for example, through a wired or wireless manner. In this implementation, the electronic device may receive, for example, a "target device list, a time-consuming parameter of the first data acquisition mode, and a time-consuming parameter of the second data acquisition mode" from the device management platform. Alternatively, the electronic device may further obtain one or more of "the target device list, the time-consuming parameters of the first data acquisition mode, and the time-consuming parameters of the second data acquisition mode" from the device management platform.
In some embodiments, the electronic device may also receive, for example, a list of target devices entered by the user, time consuming parameters of the first data acquisition mode, and time consuming parameters of the second data acquisition mode. The electronic device may, for example, receive at least one of a user entered "list of target devices, time consuming parameters of the first data acquisition mode, and time consuming parameters of the second data acquisition mode" via an application program interface (Application Programming Interface, API), or a graphical user interface (Graphical User Interface, GUI).
In some embodiments, at least one of the above-mentioned "target device list, time-consuming parameters of the first data acquisition mode, and time-consuming parameters of the second data acquisition mode" may also be, for example, pre-stored in the electronic device. That is, the electronic device may acquire at least one of the "target device list, the time-consuming parameter of the first data acquisition mode, and the time-consuming parameter of the second data acquisition mode" from the data stored in itself.
S102, determining a first time length required for data acquisition of signal points of N target devices by using the first data acquisition mode according to the target device list and time consumption parameters of the first data acquisition mode.
For example, the electronic device may predict, according to the time-consuming parameter of the first data acquisition mode, a time period required for data acquisition of the signal point of one target device in the target device list using the first data acquisition mode. The electronic device may then multiply the duration by N to obtain the first duration. Or, the electronic device may predict a time period required for data acquisition of the signal point of each target device in the target device list using the first data acquisition mode according to the time-consuming parameter of the first data acquisition mode. Then, the electronic device may take the sum of the durations corresponding to each target device as the first duration.
Alternatively, the electronic device may calculate, for example, a first time period required for data acquisition of all signal points of the N target devices using the first data acquisition mode.
Alternatively, the electronic device may calculate, for example, a first time period required for data acquisition of at least one target signal point of the N target devices using the first data acquisition mode. For any target device, the target signal point of the target device may be one or more of all signal points of the target device.
S103, determining a second time length required for data acquisition of the signal points of the N target devices by using the second data acquisition mode according to the target device list and the time consumption parameters of the second data acquisition mode.
For example, the electronic device may predict a time period required for data acquisition of a signal point of one target device in the target device list using the second data acquisition mode according to a time-consuming parameter of the second data acquisition mode. The electronic device may then multiply the duration by N to obtain the second duration. Or, the electronic device may predict a time period required for data acquisition for the signal point of each target device in the target device list using the second data acquisition mode according to the time-consuming parameter of the second data acquisition mode. Then, the electronic device may take the sum of the durations corresponding to each target device as the second duration.
Alternatively, the electronic device may calculate, for example, a second time period required for data acquisition of all signal points of the N target devices using the second data acquisition mode. Alternatively, the electronic device may calculate, for example, a second time period required for data acquisition of at least one target signal point of the N target devices using a second data acquisition mode.
It should be understood that the present application is not limited to the order in which the electronic devices perform S102 and S103. Alternatively, the electronic device may first perform S102, and then perform S103. Alternatively, the electronic device may also perform S103 first and then S102. Still alternatively, the electronic apparatus may also perform S102 and S103 simultaneously.
S104, taking the data acquisition mode corresponding to the smaller value in the first time length and the second time length as a target data acquisition mode, and carrying out data acquisition on the signal points of the N target devices through the target data acquisition mode to obtain the data of each signal point.
That is, if the first time period is less than the second time period, the electronic device may determine that the target data acquisition mode is the first data acquisition mode. If the first time length is longer than the second time length, the electronic device can determine that the target data acquisition mode is the second data acquisition mode.
If the first time length is equal to the second time length, optionally, the electronic device may randomly determine that one data acquisition mode is the target data acquisition mode from the first data acquisition mode and the second data acquisition mode, for example. Or when the first time length is equal to the second time length, the electronic device may further determine that the preset data acquisition mode is the target data acquisition mode, for example. The preset data acquisition mode may be, for example, the first data acquisition mode or the second data acquisition mode.
Optionally, the electronic device may perform data acquisition on all signal points of the N target devices through a target data acquisition mode, to obtain data of each signal point. Or the electronic device may perform data acquisition on at least one target signal point of the N target devices, for example, through a target data acquisition mode, to obtain data of the target signal point.
In this embodiment, the first time length required for data acquisition of the signal points of the N target devices using the first data acquisition mode may be determined by the target device list and the time-consuming parameters of the first data acquisition mode. The second time period required for data acquisition of the signal points of the N target devices using the second data acquisition mode can be determined by the target device list and the time consuming parameters of the second data acquisition mode. Furthermore, the electronic device may use the data acquisition mode corresponding to the smaller value in the first duration and the second duration as the target data acquisition mode, and perform data acquisition on the signal points of the N target devices according to the target data acquisition mode, so as to obtain the data of each signal point. By the method, dynamic decision of the data acquisition mode is realized, so that the electronic equipment always adopts the data acquisition mode with shorter time consumption to acquire data, and the data acquisition efficiency is improved.
Taking the electronic equipment as an example, the electronic equipment is further connected with the equipment management platform, after the electronic equipment acquires the data of the signal points of the N pieces of target equipment through the target data acquisition mode to obtain the data of each signal point, the data of each signal point can be sent to the equipment management platform, so that the equipment management platform monitors the N pieces of target equipment according to the data of each signal point.
Optionally, the electronic device may send the data of each signal point to the device management platform in a wired or wireless manner.
It should be understood that the present application does not limit how the device management platform monitors the N target devices according to the data of each signal point. For any target device, the device management platform may detect a fault of the target device according to the data of the signal point, and output alarm information when the fault detection result indicates that the target device has a fault, so that a user may know the target device having the fault as soon as possible. Optionally, the monitoring operation performed by the device management platform according to different target devices may be different or the same for different target devices.
In this embodiment, by sending the data of each signal point to the device management platform, the device management platform may monitor the target device, thereby implementing automatic monitoring on N devices, reducing the calculation amount of the electronic device, and reducing the requirement on the calculation capability of the electronic device.
In some embodiments, the electronic device may further monitor the N target devices directly according to the data of each signal point after obtaining the data of each signal point.
Taking the target data acquisition mode as a first data acquisition mode as an example, how the electronic equipment performs data acquisition on signal points of N target equipment through the target data acquisition mode to obtain data of each signal point for detailed description:
as one possible implementation, the electronic device may send a first data query frame to N target devices in a signal point-by-signal point poll manner, and receive response frames from each target device. The first data query frame is used for indicating the target device to feed back the data of the target signal point, and the first data query frame includes: identification of the target signal point. The response frame includes: data of the target signal point.
For example, taking the number of the target signal points as M (M may be less than or equal to the total number of signal points included in the N target devices) and the electronic device as an edge computing host, fig. 3 is a schematic flow chart of a first data collection mode provided in the present application. As shown in fig. 3, the specific procedure of "polling signal point by signal point" may be, for example:
the electronic device sends a first data query frame for indicating the target device to feed back the data of the target signal point 1 to the target device where the target signal point 1 is located, and receives a response frame which is fed back by the target device and comprises the data of the target signal point 1.
Then, the electronic device sends a first data query frame for indicating the target device to feed back the data of the target signal point 2 to the target device where the target signal point 2 is located, and receives a response frame including the data of the target signal point 2 fed back by the target device.
Then, the electronic device sends a first data query frame for indicating the target device to feed back the data of the target signal point 3 to the target device where the target signal point 3 is located, and receives a response frame including the data of the target signal point 3 fed back by the target device.
And so on until the electronic device acquires the data of the M target signal points.
For any response frame, after receiving the response frame, the electronic device may parse the response frame to obtain data of the target signal point from the response frame. It should be understood that the present application is not limited to how the electronic device parses the response frame to obtain the data of the target signal point.
In this implementation, the time consuming parameters in the first data acquisition mode include: the length of time Tb required for transmitting a single byte between the electronic device and the target device, the length of time Nb of the first data query frame, the length of time Nr of the response frame, the length of time Tr required for the target device to acquire the data of the target signal points from the first data query frame, and the length of time Te required for the electronic device to parse the data of the target signal points from the response frame are taken as examples, how the electronic device determines the first time length required for acquiring the data of the signal points of N target devices by using the first data acquisition mode according to the list of target devices and the time consumption parameter of the first data acquisition mode, and details are described:
as a possible implementation manner, for any target signal point, the electronic device may obtain the first data transmission duration according to the result of multiplying the sum of the byte length Nb of the first data query frame and the byte length Nr of the response frame by the duration Tb required for transmitting a single byte with the target device. Then, the electronic device may obtain a first sub-duration Tm1 required for data acquisition of the target signal point using the first data acquisition mode according to a sum of the first data transmission duration and a length Tr required by the target device from receiving the first data query frame to acquiring the data of the target signal point, and a length Te required for resolving the data of the target signal point from the response frame.
The electronic device may obtain the first sub-duration Tm1 required for data acquisition of the target signal point using the first data acquisition mode, for example, by the following formula (1):
Tm1＝(Nb+Nr)×Tb+Tr+Te (1)
after obtaining the first sub-duration Tm1 required for data collection of the target signal point using the first data collection mode, the electronic device may obtain the first duration according to the first sub-duration Tm1 and the target device list.
For example, assuming that the length of time Tb required for transmitting a single byte between the electronic device and each target device is equal, the length of time Nb of the byte of the first data query frame corresponding to each target signal point is equal, the length of time Nr of the response frame corresponding to each target signal point is equal, the length of time Tr required for each target device from receiving the first data query frame to acquiring the data of the target signal point is equal, and the length of time Te required for the electronic device to parse the data of the target signal point from each response frame is equal, the first sub-length of time Tm1 corresponding to each target signal point is equal. Therefore, the electronic device may acquire the first time length by the following formula (2):
T1＝M×Tm1 (2)
wherein T1 represents a first duration, M represents M target signal points of N target devices included in the target device list, and Tm1 represents a first sub-duration required for data acquisition of one target signal point using the first data acquisition mode.
In some embodiments, if the time length Tb required for transmitting a single byte is different between the electronic device and different target devices, or the byte length Nb of the first data query frame corresponding to different target signal points is different, or the byte length Nr of the response frame corresponding to different target signal points is different, or the time length Tr required for the different target devices from receiving the first data query frame to acquiring the data of the target signal points is different, or the time length Te required for the electronic device to parse the data of the target signal points from the different response frames is different, the electronic device may refer to the first sub-time length Tm1 corresponding to each target signal point of the predicted point according to the method for each target signal point. Then, the electronic device may add the first sub-duration corresponding to each target signal point to obtain the first duration.
In this embodiment, the electronic device may perform data acquisition on signal points of N target devices by using a first data acquisition manner, to obtain data of each signal point. The time-consuming parameters of the first data acquisition mode can be used for acquiring the first time length required by data acquisition of the signal points of N target devices by using the first data acquisition mode, so that a foundation is laid for the follow-up determination of the target data acquisition mode.
Taking the target data acquisition mode as the second data acquisition mode as an example, how the electronic equipment performs data acquisition on the signal points of the N target equipment through the target data acquisition mode to obtain the data of each signal point, and performing detailed description:
as one possible implementation, for any target device, the electronic device may send a second data query frame to the target device and receive a response frame from the target device. The second data query frame is used for indicating the target device to feed back the target memory data. The target memory data may include: data of at least one target signal point. The response frame may include: the target memory data. Then, the electronic device may parse the target memory data to obtain data of at least one target signal point.
Optionally, the number of target signal points included in different target memory data may be the same or different. It should be understood that the present application is not limited to the number of target memory data included in one target device.
For example, still taking the number of the target signal points as M (M may be less than or equal to the total number of signal points included in the N target devices) as an example, the electronic device is an edge computing host, and fig. 4 is a schematic flow chart of a second data collection mode provided in the present application. As shown in fig. 4, the specific procedure of the second data acquisition mode may be, for example:
The electronic device sends a second data query frame for indicating the target device to feed back the target memory data 1 to the target device where the target memory data 1 is located, and receives a response frame including the target memory data 1 fed back by the target device. Then, the electronic device may analyze the target memory data 1 to obtain data of the target signal point 1, data of the target signal point 2, and data of the target signal point 3.
Then, the electronic device sends a second data query frame for indicating the target device to feed back the target memory data 2 to the target device where the target memory data 2 is located, and receives a response frame including the target memory data 2 fed back by the target device. Then, the electronic device may analyze the target memory data 2 to obtain the data of the target signal point 4 and the data of the target signal point 5.
It should be understood that the target device where the target memory data 2 is located and the target device where the target memory data 1 is located may be the same target device or may be different target devices.
And so on until the electronic equipment acquires the data of the M target signal points.
It should be understood that the present application is not limited to how the electronic device analyzes the target memory data to obtain the data of at least one target signal point. Optionally, reference may be made to any existing method for analyzing data to obtain data of a signal point, which is not described herein.
In this implementation manner, the byte length of the target memory data is a preset length, the storage addresses of the target memory data are continuous, and the time-consuming parameters of the second data acquisition mode include: the method includes the steps of analyzing a byte length Nm of target memory data, a byte length Nc of a second data query frame, a time length required for analyzing the target memory data from a response frame and analyzing data of a single target signal point, a time length Tb required for transmitting a single byte between an electronic device and the target device, and a time length Ts required for the target device from receiving the second data query frame to acquiring the target memory data, wherein how the electronic device determines a second time length required for data acquisition of the signal points of N target devices using the second data acquisition mode according to a target device list and time-consuming parameters of the second data acquisition mode is described in detail:
as a possible implementation manner, for any target device, the electronic device may multiply the result of the duration Tb required for transmitting a single byte with the target device according to the sum of the byte length Nc of the second data query frame and the byte length Nm of the target memory data, and the length Ts required for the target device from receiving the second data query frame to acquiring the target memory data, to obtain the second data transmission duration.
The electronic device may obtain the second data transmission duration by, for example, the following equation (3):
Tsm＝(Nm+Nc)×Tb+Ts (3)
where Tsm represents the second data transmission duration. Nm represents the byte length of the target memory data. Nc represents the byte length of the second data query frame. Tb represents the length of time required to transfer a single byte between the electronic device and the target device. Ts represents the length of time required for the target device from receiving the second data query frame to acquiring the target memory data.
The electronic device may then obtain the memory addresses of all target signal points of the target device. The storage addresses of all target signal points of the target device may be carried in the target device list, for example. In some embodiments, the user may also modify the target signal point, so that the electronic device executes the data acquisition method to perform data acquisition on other target signal points. Alternatively, the electronic device may also receive, for example, a storage address of all target signal points of each target device input by the user.
Then, the electronic device may determine the number of times to send the second data query frame to the target device according to the storage addresses of all the target signal points of the target device.
Optionally, because the storage addresses of the target memory data are continuous, the electronic device may sort the storage addresses of the target signal points from small to large according to the storage addresses of all the target signal points, and determine the number of times of sending the second data query frame to the target device according to the byte length of the target memory data. Illustratively, the electronic device may obtain the number of times the second data query frame is transmitted to the target device according to the following equation (4):
K＝DA÷Nm+1 (4)
where K represents the number of times the second data query frame is sent to the target device. DA represents the difference between the memory address of the first target signal point and the memory address of the last target signal point. Nm represents the byte length of the target memory data.
Still taking fig. 4 as an example, assuming that all the target signal points of the target device are the target signal point 1, the target signal point 2, the target signal point 3, the target signal point 4, the target signal point 5, and the target signal point 6, the number of times that the electronic device sends the second data query frame to the target device is 3.
Then, the electronic device may obtain a third data transmission duration according to the product of the number K of times of sending the second data query frame to the target device and the second data transmission duration. The electronic device may obtain the third data transmission duration by, for example, the following equation (5):
Ta＝Tsm×K (5)
Wherein Ta represents the third data transmission period.
After the third data transmission duration is obtained, the electronic device may obtain a second duration according to the third data transmission duration and the target device list.
The third data transmission duration is a duration required by the electronic device to acquire all the target memory data in one target device. Thus, the electronic device may obtain the second duration, for example, according to the following equation (6):
T2＝Ta×N+M×Tf (6)
where N represents the number of target devices included in the target device list. M represents M target signal points of N target devices. Tf represents the time period required by the electronic device to parse the target memory data from the response frame and parse the data of a single target signal point.
In this embodiment, the electronic device may perform data acquisition on signal points of the N target devices in the second data acquisition manner, to obtain data of each signal point. The time-consuming parameters of the second data acquisition mode can be used for acquiring the second time length required by data acquisition of the signal points of the N target devices by using the second data acquisition mode, so that a foundation is laid for the follow-up determination of the target data acquisition mode.
