The drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the concepts of the application by those skilled in the art with reference to specific embodiments.
Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
A large number of electronic devices (e.g., sensing devices and execution devices, etc.) are typically deployed in a factory. At least one signal point may be provided on one electronic device. For example, taking an electronic device including a motor as an example, a sensing device for detecting the rotational speed of the motor, an actuator for controlling the rotational speed of the motor, and the like of the electronic device are signal points of the electronic device.
In a factory digital scene, in order to realize the unified monitoring of the electronic equipment, the edge computing host can be interconnected with the electronic equipment, so as to acquire data of signal points of the equipment and carry out the unified monitoring on the electronic equipment according to the acquired data.
Taking a signal point as an example of the sensing device, the data of the signal point may be data (e.g., temperature, humidity, rotation speed, etc.) detected by the sensing device. Taking a signal point as an execution device as an example, the data of the signal point may be data (such as rotation speed, voltage, current, etc.) output by the execution device.
At present, the existing data acquisition methods mainly include the following two methods:
1. acquiring data of signal points of each electronic device in a polling mode one by one: and the edge calculation host acquires the signal point data in a polling mode one by one through the query command until all the signal points of the electronic equipment are acquired. When the number of signal points is small, the method can complete data acquisition more quickly. However, the data acquisition method consumes more time when there are more signal points, and has low data acquisition efficiency and poor data real-time performance.
2. Data for a plurality of signal points is acquired simultaneously. And the edge computing host acquires a section of memory data with a preset length of the electronic equipment when the edge computing host passes the query command. The memory data of the preset length may include data of a plurality of signal points. When the memory data with the preset length comprises more signal point data, the data of a plurality of signal points can be acquired through one section of memory data with the preset length, and higher data acquisition efficiency can be realized. However, when the memory data with the preset length includes less signal point data, since the memory data with the preset length takes a certain time to transmit, the average acquisition time of each signal point data is increased, thereby reducing the acquisition efficiency of the signal point data.
Therefore, the existing data acquisition methods all have the problem of low data acquisition efficiency.
In view of 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 acquiring data in a data acquisition mode with short time so as to improve the data acquisition efficiency. Optionally, an execution main body of the data acquisition mode provided by the present application may be any electronic device, such as a terminal and a server, having a processing function.
Taking the above-mentioned 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 present application does not limit the connection manner between the edge computing host and the N devices. Illustratively, the edge computing host and the N devices may be connected by wireless communication. The wireless communication method may be, for example, a communication method based on OPC UA communication protocol. The OPC UA is generally called OLE for Process Control. OLE is called Object Linking and Embedding. Alternatively, the wireless communication method may be, for example, a communication method based on MODBUS communication protocol.
In addition, it should be understood that the present application does not limit the types of the target devices and the types of the signal points (e.g., sensors or actuators, etc.) of the target devices.
The technical solution of the present application will be described in detail with reference to specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 2 is a schematic flow chart of a data acquisition method provided in the present 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.
Wherein, the target device list may include: and N identifiers of target equipment 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 consumption 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. Illustratively, the time-consuming parameters of the data acquisition mode may include, for example, at least one of: the time length required by the electronic equipment to transmit a single byte with the target equipment, the time length required by the target equipment to acquire the data of the signal point, the time length required by the electronic equipment to analyze the data of the target signal point from the response frame of the target equipment and the like.
It should be appreciated that the first data acquisition mode described above may be any one of the existing data acquisition modes. The second data acquisition mode may be any one of the existing data acquisition modes different from the first data acquisition mode. For example, the first data acquisition mode is the 1 st data acquisition method described in the foregoing prior art, and the second data acquisition mode may be, for example, the 2 nd data acquisition method described in the foregoing prior art.
Optionally, as shown in fig. 1, taking an electronic device as an edge computing host as an example, the electronic device may also be connected to the device management platform in a wired or wireless manner, for example. In this implementation, the electronic device may receive, for example, a "list of target devices, 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. Or, the electronic device may further obtain one or more 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 device management platform.
In some embodiments, the electronic device may also receive user input of a list of target devices, a time-consuming parameter for the first data acquisition mode, and a time-consuming parameter for the second data acquisition mode, for example. Illustratively, the electronic device may receive, for example, through an Application Programming Interface (API) or a Graphical User Interface (GUI), at least one of 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, which are input by a User.
In some embodiments, at least one of the "target device list, the time consumption parameter of the first data acquisition mode, and the time consumption parameter of the second data acquisition mode" may also be pre-stored in the electronic device, for example. That is, the electronic device may obtain 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 the electronic device.
S102, according to the target equipment list and time consumption parameters of the first data acquisition mode, determining a first time length required for data acquisition of the signal points of the N target equipment by using 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 duration required for data acquisition of a signal point of one target device in the target device list using the first data acquisition mode. Then, the electronic device may multiply the time length by N to obtain the first time length. Or, the electronic device may also predict, according to the time-consuming parameter of the first data acquisition mode, a time duration required for data acquisition of the signal point of each target device in the target device list using the first data acquisition mode. Then, the electronic device may use the sum of the time lengths corresponding to each target device as the first time length.
Alternatively, the electronic device may, for example, calculate 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, for example, calculate 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 signal points of all signal points of the target device.
S103, according to the target equipment list and the time consumption parameters of the second data acquisition mode, determining a second time length required for performing data acquisition on the signal points of the N target equipment by using the second data acquisition mode.
For example, the electronic device may predict, according to the time-consuming parameter of the second data acquisition mode, a time duration required for data acquisition of a signal point of one target device in the target device list using the second data acquisition mode. Then, the electronic device may multiply the time length by N to obtain the second time length. Or, the electronic device may also predict, according to the time consumption parameter of the second data acquisition mode, a time length required for data acquisition of the signal point of each target device in the target device list using the second data acquisition mode. Then, the electronic device may use the sum of the time lengths corresponding to each target device as the second time length.
Alternatively, the electronic device may calculate a second time period required for data acquisition of all signal points of the N target devices using the second data acquisition mode, for example. Alternatively, the electronic device may, for example, calculate a second time period required for data acquisition of at least one target signal point of the N target devices using the second data acquisition mode.
It should be understood that the order in which the electronic device executes S102 and S103 is not limited in the present application. Optionally, the electronic device may first execute S102 and then execute S103. Alternatively, the electronic device may first execute S103 and then execute S102. Still alternatively, the electronic device may also perform S102 and S103 simultaneously.
And S104, taking a data acquisition mode corresponding to the smaller value of the first duration and the second duration as a target data acquisition mode, and acquiring data of the signal points of the N pieces of target equipment through the target data acquisition mode to obtain data of each signal point.
That is, if the first duration is less than the second duration, the electronic device may determine that the target data collection mode is the first data collection mode. If the first duration is longer than the second duration, the electronic device may 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 one data acquisition mode as the target data acquisition mode from the first data acquisition mode and the second data acquisition mode, for example. Alternatively, when the first duration is equal to the second duration, the electronic device may further determine, for example, a preset data acquisition mode as the target data acquisition mode. 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, for example, 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 in a target data acquisition mode, for example, to obtain data of the target signal point.
In this embodiment, through the list of target devices and the time consumption parameter of the first data acquisition mode, a first time length required for performing data acquisition on the signal points of the N target devices by using the first data acquisition mode may be determined. And determining a second time length required for acquiring data 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. Furthermore, the electronic device may use a data acquisition mode corresponding to a smaller value of the first duration and the second duration as a target data acquisition mode, and perform data acquisition on the signal points of the N target devices through the target data acquisition mode to obtain data of each signal point. By the method, dynamic decision of the data acquisition mode is realized, so that the electronic equipment always acquires data by adopting a data acquisition mode with short time consumption, and the data acquisition efficiency is improved.
Taking the example that the electronic device is further connected with the device management platform, the electronic device performs data acquisition on the signal points of the N target devices in a target data acquisition mode to obtain data of each signal point, and then can also send the data of each signal point to the device management platform, so that the device management platform monitors the N target devices 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, in the present application, there is no limitation on how the device management platform monitors the N target devices according to the data of each signal point. For example, for any target device, the device management platform may perform fault detection on the target device according to data of the signal point, and output alarm information when a 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 device management platform may perform different monitoring operations or the same monitoring operation according to different target devices, for different target devices.
In this embodiment, by sending the data of each signal point to the device management platform, the device management platform can monitor the target device, thereby implementing automatic monitoring of N devices, reducing the amount of computation of the electronic device, and reducing the requirement for the computing 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.
In the following, taking the target data acquisition mode as the first data acquisition mode as an example, how the electronic device performs data acquisition on the signal points of the N target devices through the target data acquisition mode to obtain data of each signal point is described in detail:
as a possible implementation manner, the electronic device may send the first data query frame to the N target devices and receive the response frame from each target device in a signal point-by-signal point polling manner. The first data query frame is used for indicating the target device to feed back 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 is an edge computing host, fig. 3 is a schematic flow chart of a first data acquisition mode provided in the present application. As shown in fig. 3, the specific process of "polling signal point by signal point" may be, for example:
the electronic device firstly sends a first data query frame of 'data for instructing the target device to feed back the target signal point 1' to the target device where the target signal point 1 is located, and receives a response frame including the data of the target signal point 1 fed back by the target device.
Then, the electronic device sends a first data query frame indicating that the target device feeds back 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 transmits a first data query frame for instructing the target device to feed back 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 repeating the steps until the electronic equipment 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 the 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: for an example, how the electronic device determines, according to the target device list and the time consumption parameter of the first data acquisition mode, a first time length required for performing data acquisition on signal points of the N target devices by using the first data acquisition mode, according to a time length Tb required for transmitting a single byte between the electronic device and the target device, a byte length Nb of the first data query frame, a byte length Nr of the response frame, a time length Tr required for the target device to acquire data of the target signal point from the reception of the first data query frame, and a time length Te required for the target device to analyze the data of the target signal point from the response frame, the detailed description will be given below:
as a possible implementation manner, for any target signal point, the electronic device may obtain the first data transmission time length according to a 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 time length Tb required for transmitting a single byte with the target device. Then, the electronic device may obtain a first sub-time length Tm1 required for data acquisition of the target signal point by using the first data acquisition mode according to the sum of the first data transmission time length and a time length Tr required by the target device from receiving the first data query frame to acquiring the data of the target signal point, and the sum of time lengths Te required by the target device to analyze the data of the target signal point from the response frame.
For example, the electronic device may obtain the first sub-period 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-time duration Tm1 required for data acquisition of the target signal point by using the first data acquisition mode, the electronic device may obtain the first time duration according to the first sub-time duration Tm1 and the target device list.
For example, assuming that time lengths Tb required for transmitting a single byte between the electronic device and each target device are all equal, a byte length Nb of a first data query frame corresponding to each target signal point is all equal, a byte length Nr of a response frame corresponding to each target signal point is all equal, time lengths Tr required for each target device from receiving the first data query frame to acquiring data of the target signal points are all equal, and time lengths Te required for the electronic device to analyze the data of the target signal points from each response frame are all equal, first sub-time lengths Tm1 corresponding to each target signal point are all equal. Therefore, the electronic device may obtain the first time length by the following equation (2):
T1＝M×Tm1 (2)
wherein, T1 represents a first time duration, M represents M target signal points of N target devices included in the target device list, and Tm1 represents a first sub-time 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 between the electronic device and different target devices is different, 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 acquiring data of the target signal points from the reception of the first data query frame by different target devices is different, or the time length Te required for the electronic device to analyze data of the target signal points from different response frames is different, the electronic device may predict, for each target signal, the first sub-time length Tm1 corresponding to each target signal point respectively by referring to the method described above. Then, the electronic device may add the first sub-durations corresponding to each target signal point to obtain the first duration.
In this embodiment, the electronic device may perform data acquisition on the signal points of the N target devices in a first data acquisition manner to obtain data of each signal point. The first time length required for carrying out data acquisition on the signal points of the N target devices by using the first data acquisition mode can be obtained through the time-consuming parameters of the first data acquisition mode, and a foundation is laid for subsequently determining a target data acquisition mode.
Taking the target data acquisition mode as the second data acquisition mode as an example, how the electronic device performs data acquisition on the signal points of the N target devices through the target data acquisition mode to obtain data of each signal point is described in detail below:
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 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 analyze 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 also does not limit 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) and the electronic device as an edge computing host as an example, fig. 4 is a schematic flow chart of a second data acquisition mode provided in the present application. As shown in fig. 4, the specific process of the second data acquisition mode may be, for example:
the electronic device first sends a second data query frame for instructing 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 instructing 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 data of the target signal point 4 and 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 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 application is not limited to how the electronic device parses the target memory data to obtain data of at least one target signal point. Optionally, any existing method for analyzing data to obtain data of a signal point may be referred to, and details of this application are not repeated 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 parameter of the second data acquisition mode includes: the following describes in detail how the electronic device determines, according to the target device list and time consumption parameters of the second data acquisition mode, a second time period required for data acquisition of signal points of N target devices using the second data acquisition mode, by taking, as an example, a byte length Nm of target memory data, a byte length Nc of a second data query frame, a time period required for parsing out the target memory data from a response frame and parsing out data of a single target signal point, a time period required for transmitting a single byte between the electronic device and the target device, and a time period Ts required for the target device to acquire the target memory data from receiving the second data query frame:
as a possible implementation manner, for any target device, the electronic device may obtain the second data transmission time length 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, multiplied by the result of the time length Tb required for transmitting a single byte with the target device, and the time length Ts required by the target device from receiving the second data query frame to obtaining the target memory data.
Illustratively, the electronic device may obtain the second data transmission duration by, for example, the following formula (3):
Tsm＝(Nm+Nc)×Tb+Ts (3)
where Tsm denotes a second data transmission duration. Nm denotes the byte length of the target memory data. Nc denotes the byte length of the second data query frame. Tb represents the time period required for transmitting a single byte between the electronic device and the target device. And Ts represents the time length from the receiving of the second data query frame to the acquisition of the target memory data by the target equipment.
Then, the electronic device may acquire the memory addresses of all the 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 further modify the target signal point, so that the electronic device executes the data acquisition method to acquire data of other target signal points. Alternatively, the electronic device may also receive, for example, user-input storage addresses of all target signal points of the respective target devices.
The electronic device may then determine the number of times to transmit the second data query frame to the target device based on the memory addresses of all of 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. For example, the electronic device may obtain the number of times to transmit the second data query frame to the target device according to the following formula (4):
K＝DA÷Nm+1 (4)
where K represents the number of times a second data query frame is sent to the target device. DA denotes the difference between the memory address of the first target signal point and the memory address of the last target signal point. Nm denotes 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 target signal point 1, target signal point 2, target signal point 3, target signal point 4, target signal point 5, and 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 a product of the number K of times that the second data query frame is transmitted to the target device and the second data transmission duration. Illustratively, the electronic device may obtain the third data transmission duration by, for example, the following formula (5):
Ta＝Tsm×K (5)
where Ta denotes the third data transmission duration.
After obtaining the third data transmission duration, 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 target memory data in one target device. Therefore, the electronic device may obtain the second duration according to the following equation (6), for example:
T2＝Ta×N+M×Tf (6)
where N represents the number of target devices included in the target device list. M denotes M target signal points of N target devices. And Tf represents the time length required by the electronic equipment to analyze the target memory data from the response frame and analyze the data of a single target signal point.
In this embodiment, the electronic device may perform data acquisition on the signal points of the N target devices in a 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 the data acquisition of the signal points of the N target devices by using the second data acquisition mode, and a foundation is laid for subsequently determining a target data acquisition mode.
