In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Example 1:
fig. 1 shows a flowchart of an implementation of a data polling method according to an embodiment of the present invention, and for convenience of description, only the relevant portions of the embodiment of the present invention are shown, and the following details are described below:
s101: sending a polling instruction set to monitored equipment according to a first polling period, wherein the polling instruction set is used for indicating the monitored equipment to return data corresponding to each measuring point group, and the data comprises at least one group of analog data; the polling instruction set comprises at least one analog polling instruction; each analog polling instruction corresponds to an analog polling period.
The execution subject of this embodiment may include a monitoring server or a monitoring terminal, and the following explanation takes the monitoring terminal as an example. The monitored equipment may include, but is not limited to, UPSs (uninterruptible power supplies), energy storage devices, and other equipment that generates analog quantities.
In this embodiment, when data polling is performed on the monitored equipment for the first time, the terminal equipment sends a polling instruction set to the monitored equipment according to a fixed first polling period, where the polling instruction set includes at least one analog polling instruction and at least one state polling instruction, and each analog polling instruction carries an identification number of a corresponding group of analog measurement points, and is used to query analog data of the group of analog measurement points in the monitored equipment; each state quantity polling instruction carries the identification number of a corresponding group of state measurement points and is used for inquiring the state data of a group of state measurement points in the monitored equipment. The measuring point group of the analog quantity comprises at least one measuring point, and each measuring point detects one analog quantity; a state quantity measuring point group includes at least one measuring point, and each measuring point detects a state quantity. And there is a correlation between each measurement point in one analog quantity measurement point group, for example, the measurement points queried by the same analog quantity polling command are all output voltage related measurement points of the device.
Illustratively, the polling instruction set comprises four analog quantity polling instructions and one strip state quantity polling instruction, wherein one analog quantity polling instruction corresponds to the inquiry of analog data of ten measuring points, and one strip state quantity polling instruction corresponds to the inquiry of state data of ten measuring points. Then the simulation data for forty stations and the status data for ten stations are queried for each first polling cycle.
In this embodiment, the analog data may include, but is not limited to, analog quantities such as voltage, current, power, and the like, and the status data may include, but is not limited to, states such as switch status, normal, abnormal, and alarm.
S102: and acquiring the simulation data of the measuring point group corresponding to each analog quantity polling instruction sent by the monitored equipment.
S103: and updating the analog polling period corresponding to the first analog polling instruction according to the analog data of the measuring point group corresponding to the first analog polling instruction, wherein the first analog polling instruction is any one analog polling instruction.
In this embodiment, since there is a correlation between a set of measurement points, the data change thereof usually has a similar rule, and therefore, the average value of the analog data change amounts of two analog polling periods before and after each measurement point in a set of measurement points can be taken to determine whether to update the analog polling period corresponding to the analog data.
Specifically, at the beginning of data polling, the analog polling period and the state polling period are the same as the first polling period, if the change amplitude of the analog data of the first analog polling instruction in the current analog polling period and the previously acquired analog data is within the preset amplitude range, the analog polling period of the analog polling instruction is kept unchanged, and if the change amplitude of the analog data of the analog polling instruction is smaller than the minimum value of the preset amplitude range, the analog polling period corresponding to the analog polling instruction is prolonged, so that the terminal device acquires less analog data of the test point group corresponding to the analog polling instruction, thereby reducing the acquisition of unnecessary data and improving the data polling efficiency. If the variation amplitude of the analog data corresponding to the analog quantity polling instruction is larger than the maximum value of the preset amplitude range, the analog data corresponding to the analog quantity polling instruction is changed faster, so that the analog quantity polling period of the test point group corresponding to the first analog quantity polling instruction can be shortened, and the timely effectiveness of data polling is ensured.
According to the embodiments, by the scheme, each analog polling period can be dynamically adjusted according to the test point analog data corresponding to each analog polling instruction, so that the timeliness of data polling is improved.
In an embodiment, as shown in fig. 2, fig. 2 shows a specific implementation flow of S103 in fig. 1, which includes:
s201: taking the difference value between the simulation data of the first measuring point corresponding to the first analog quantity polling instruction in the current analog quantity polling period and the simulation data of the previous analog quantity polling period as a first difference value, wherein the first measuring point is any measuring point in the measuring point group corresponding to the first analog quantity polling instruction;
s202: averaging first difference values of all measuring points corresponding to the first analog quantity polling instruction to obtain a first difference value average value;
s203: and if the first difference average value is smaller than a first preset difference threshold value, prolonging the analog quantity polling period corresponding to the first analog quantity polling instruction.
S204: and if the first difference average value is larger than a second preset difference threshold value, shortening the analog quantity polling period corresponding to the first analog quantity polling instruction.
In this embodiment, the specific implementation flow of S202 in fig. 2 includes:
and if the first difference average value is smaller than a first preset difference threshold value, updating the next analog polling period of the first analog polling instruction to be a multiple of the analog polling period.
In this embodiment, after determining that the first difference average value is smaller than the first preset difference threshold, the next analog polling period corresponding to the first analog polling command may be updated to be a multiple of the initial analog polling period. In the next analog polling period, if the first difference value is detected to be greater than or equal to a first preset difference threshold value and smaller than a second preset difference threshold value, adjusting the next analog polling period corresponding to the first analog polling instruction back to the initial analog polling period.
For example, it is assumed that when the first difference value is smaller than the first preset difference threshold, the next analog polling cycle of the first analog polling instruction is updated to be 2 times of the current analog polling cycle, that is, the query of the corresponding station group of the next analog polling instruction is skipped. If the query time corresponding to each analog quantity polling instruction and each state quantity polling instruction is 5 seconds, the total polling time required by the four analog quantity polling instructions and the 1 state quantity polling instruction is 25 seconds, and when the next polling period skips the polling of a point corresponding to the first analog quantity polling instruction, the polling time of the next polling period can be shortened to 20 seconds.
In an embodiment, as shown in fig. 3, fig. 3 shows another specific implementation flow of S103 in fig. 1, which includes:
s301: inputting simulation data and historical simulation data corresponding to the test point group corresponding to the first analog quantity polling instruction in the current analog quantity polling period into a preset learning model, and outputting prediction simulation data of the test point group corresponding to the first analog quantity polling instruction in the next analog quantity polling period;
s302: and updating the analog quantity polling period of the first analog quantity polling instruction according to the predicted analog data corresponding to the measuring point group corresponding to the first analog quantity polling instruction in the next analog quantity polling period and the analog data corresponding to the current analog quantity polling period.
In this embodiment, historical simulation data may also be acquired as training samples to train the preset learning model. After the preset learning model is trained, the monitoring terminal can determine the predicted analog data of the test point group corresponding to the first data polling instruction in the next analog polling period according to the analog data and the historical analog data corresponding to the first data polling instruction in the current polling period, so that the next analog polling period of the first data polling instruction is updated according to the analog data of the current analog polling period and the predicted analog data of the next analog polling period.
In one embodiment, as shown in fig. 4, fig. 4 shows a specific implementation flow of S302 in fig. 3, and the process thereof is detailed as follows:
s401: taking the difference value between the predicted analog data of the first measuring point corresponding to the first analog polling instruction in the next analog polling period and the analog data corresponding to the current analog polling period as a second difference value; the first measuring point is any measuring point in the measuring point group corresponding to the first analog quantity polling instruction;
s402: averaging second difference values of the measuring points corresponding to the first analog quantity polling instruction to obtain a second difference value average value;
s403: and if the second difference average value is smaller than a first preset difference threshold value, prolonging the analog quantity polling period corresponding to the first analog quantity polling instruction.
Specifically, after determining that the second difference average value is smaller than the first preset difference threshold, the next analog polling cycle corresponding to the first analog polling command may be updated to be a multiple of the initial analog polling cycle.
Furthermore, in the next analog polling period, if it is detected that the second difference average value is greater than the first preset difference threshold and less than the second preset difference threshold, the next analog polling period corresponding to the first analog polling command is updated to the initial analog polling period.
In one embodiment, another specific implementation flow of S103 in fig. 1 includes:
counting the number of the test points of the simulation data in the test point group corresponding to the first analog polling instruction within a preset data range in the current analog polling period, and if the number is larger than the preset number, prolonging the analog polling period corresponding to the first analog polling instruction.
In this embodiment, the preset data range may be set as a range of data of the station during normal operation, and when the simulation data is within the normal range, the polling period of the analog quantity of the corresponding station may be appropriately extended. And because a group of measuring points corresponds to an analog quantity polling instruction, counting the number of the measuring points of which the data is in the normal range in the measuring point group, and prolonging the analog quantity polling period corresponding to the first analog quantity polling instruction when the counted number is greater than the preset number.
In one embodiment, the polling command further includes a state quantity polling command, the data further includes at least one set of state data, and step S101 in fig. 1 further includes: and sending a state quantity polling instruction to the monitored equipment according to a first polling period so as to enable the monitored equipment to return state data of the corresponding station group.
In this embodiment, the status quantity represents the status of a certain measuring point of the monitored equipment, including but not limited to on-off status, normal, abnormal, alarm, and the like.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
