Detailed Description
The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.
Example 1
Fig. 1 is a flowchart of an acquisition scheduling method of a low-voltage centralized meter reading device according to an embodiment of the present invention, where the embodiment is applicable to a case of centralized acquisition of data in a plurality of low-voltage centralized meter reading devices. The method of the embodiment can be executed by an acquisition and scheduling device of the low-voltage centralized meter reading equipment, and the device can be realized in a software and/or hardware mode and can be generally integrated in a concentrator for acquiring data in a plurality of low-voltage centralized meter reading equipment.
Correspondingly, the method specifically comprises the following steps:
s110, responding to a parameter configuration instruction of a user, forming acquisition parameter configuration information, wherein the acquisition parameter configuration information comprises the following components: a plurality of collected data items, and a priority level corresponding to each of the collected data items.
The plurality of collected data items are composed of data types required to be collected by a plurality of low-voltage meter reading devices, and can be daily freezing, load data, alarm and event record. And each collected data item can correspond to different priority levels according to the collected parameter configuration information in the plurality of low-voltage centralized meter reading devices. The priority level is the importance degree of the processing of the collected data, the priority level can be ordered from high to low, and the collected data is processed according to the collected parameter configuration information of the plurality of low-voltage meter reading devices.
In the present embodiment, the priority levels set for different collected data items are different, for example, if the number of collected data items is 4, different 4 priority levels need to be set for the above 4 collected data items.
S120, forming an acquisition sequence table according to the historical data acquisition condition of each connected low-voltage centralized meter reading device.
The low-voltage centralized meter reading system, namely the low-voltage power user centralized meter reading system, is one of core elements of the intelligent power grid. The low-voltage centralized meter reading is an information integration system which utilizes modern digital communication, computer software and hardware, automation equipment and other advanced technical frameworks, and is used for collecting, processing and monitoring the power consumption information of power users in real time so as to realize information exchange control with intelligent electric equipment. The low-voltage centralized meter reading equipment consists of a system main station, a communication channel, an acquisition terminal (data acquisition and remote control equipment such as a concentrator and an acquisition device) and an intelligent ammeter. The acquisition terminal acquires data information on the intelligent ammeter through a power line carrier, RS485 or other communication channels, and then sends the data information to a master station of a low-voltage centralized meter reading equipment system through networks such as an Ethernet, a wireless public network, an optical fiber and the like. The acquisition sequence list is a list formed according to the sequence of the acquisition data, namely the acquisition sequence of each recorded low-voltage centralized meter reading device.
Optionally, forming the acquisition sequence table according to the historical data acquisition condition of each connected low-voltage meter reading device may include: acquiring average acquisition time delay and acquisition success rate of each low-voltage centralized meter reading device at a plurality of historical acquisition moments; calculating the priority score of each low-voltage centralized meter reading device according to the average acquisition time delay and the acquisition success rate; and sequencing the low-voltage centralized meter reading equipment according to the order of the priority scores from high to low to form an acquisition sequence table.
The average acquisition time delay is the average time required by one message or packet in the data acquisition to be transmitted from one end of the device to the other end, and the acquisition success rate is the probability that the concentrator successfully acquires target acquisition data from the low-voltage centralized meter reading device.
In this embodiment, the concentrator may collect data from each low-voltage meter reading device at a plurality of historical collection times, respectively. Correspondingly, for each historical collection time, the collection time delay (the waiting time required by the process from the start of sending a collection request to one low-voltage centralized meter reading device to the process of receiving the collection data fed back by the low-voltage centralized meter reading device) and the result (the collection is successful or unsuccessful) of whether the collection is successful or not can be obtained for each low-voltage centralized meter reading device, and further, the average collection time delay and the collection success rate corresponding to each low-voltage centralized meter reading device can be obtained through summarizing and calculating according to the plurality of historical collection time points.
It can be understood that the lower the average acquisition time delay and the higher the acquisition success rate of a low-voltage centralized meter reading device, the easier the data in the low-voltage centralized meter reading device can be acquired quickly and accurately, and the higher priority score can be correspondingly set for the low-voltage centralized meter reading device, so that the low-voltage centralized meter reading device can be acquired preferentially.
The advantages of this arrangement are that: by acquiring the average acquisition time delay and the acquisition success rate of each low-voltage centralized meter reading device, when the average acquisition time delay is lower and the acquisition success rate is higher, the priority set for the low-voltage centralized meter reading device is relatively higher. Therefore, the data can be collected preferentially, so that the collection priority can be arranged more reasonably, the collected data of each low-voltage centralized meter reading device can be more flexible and accurate, and the collection optimization is realized.
And S130, when the acquisition conditions of the low-voltage centralized meter reading equipment are met, sequentially acquiring a target acquisition data item according to the order of the priority levels in the acquisition parameter configuration information from high to low.
The collection conditions refer to conditions that need to be met when the collected data items included in each low-voltage meter reading device need to be collected once, and the collection conditions may be manual trigger conditions of a user, or time conditions of periodic trigger, and the embodiment is not limited to this.
In an optional implementation manner of this embodiment, the parameter configuration instruction may further include: data cycles are acquired (e.g., every 15 minutes, every 30 minutes, every 12 hours, or every 24 hours, etc.);
correspondingly, the meeting of the collection conditions of each low-pressure meter reading device can specifically include: and when the current system time reaches an acquisition time point defined by the acquisition data period, determining that the acquisition condition of the low-voltage centralized meter reading equipment is met.
In the present embodiment, the data collection process at the current collection time point is performed once every time the collection time point for each low-voltage meter reading device is detected. Of course, when the comparison of the acquisition period setting is short, it may occur that the data acquisition process at the previous acquisition time point is not completely ended, and at this time, the data acquisition process at the previous acquisition time point may be directly terminated. Meanwhile, when the whole data acquisition process starts, it is necessary to first acquire one target acquisition data item in sequence from the higher priority level to the lower priority level in the acquisition parameter configuration information, and execute S140 for each target acquisition data item, respectively.
S140, respectively acquiring target acquisition data items from the low-voltage centralized meter reading devices according to the acquisition sequence of the low-voltage centralized meter reading devices recorded in the acquisition sequence table, and executing the operation of sequentially acquiring one target acquisition data item according to the sequence from high to low of the priority in the acquisition parameter configuration information again until the acquisition process is ended.
The acquisition parameter configuration information is information of configurable acquisition parameters, and may include: the acquisition data item, the acquisition data period, the priority level, the acquisition starting condition and the termination condition, and the configurable acquisition parameter schematic diagram is shown in fig. 2 b. Specifically, the collected data items may include daily freezing, load data, alarms or event records, etc.; the period of acquisition data may be every 15 minutes, every 30 minutes, every 12 hours, every 24 hours, etc.; priority levels may be classified as 1, 2, 3, or 4, etc.; the acquisition starting condition can be unconditional, the acquisition completion rate of the previous level or manual triggering and the like; the termination condition may be that the total acquisition time length of the acquired data item exceeds a preset acquisition waiting time length threshold or a new acquisition time point arrives, etc.
In a specific example, the acquisition data items included in the acquisition parameter configuration information include: the data acquisition system comprises a data item A, a data item B and a data item C, wherein the data item A has the highest priority level, the data item B has the lowest priority level and the data item C has the highest priority level, the acquisition starting condition of the data item A is unconditional, and the acquisition starting conditions of the data item B and the data item C are all the acquisition completion rate of the previous level which reaches 80 percent. Simultaneously, N low-voltage centralized meter reading devices, namely device 1, device 2, … and device N are sequentially recorded in the acquisition sequence table;
correspondingly, when the collection conditions of the low-pressure centralized meter reading equipment are met, the concentrator can execute the following collection operations:
1. starting a data acquisition flow of the data item (data item A) with the highest priority, executing the operation of acquiring the data item A from each low-pressure meter reading device according to the sequence from the device 1 to the device N, and updating the acquisition completion rate matched with the data item A in real time; when the acquisition completion rate reaches 80% once, triggering the start of a data acquisition process of a data item (data item B) of the next level while keeping the data item acquisition process of the priority level continuously;
2. when the data acquisition flow of the data item B is started, the operation of acquiring the data item B from each low-pressure meter reading device is executed according to the sequence from the device 1 to the device N, and the acquisition completion rate matched with the data item B is updated in real time; when the acquisition completion rate reaches 80% once, triggering the start of a data acquisition process of a data item (data item C) of the next level while keeping the data item acquisition process of the priority level continuously;
3. when the data collection flow of the data item C is started, the operation of collecting the data item C from each low-voltage meter reading device is performed in the same order from the device 1 to the device N.
It should be noted that, in the execution process of the data collection flows of the three data items, there may be no association relationship between the data collection flows of each data item, and the data collection flows of each data item may automatically stop after the execution of the data collection flows of each data item is finished (that is, all N low-voltage meter reading devices complete the collection of the corresponding data item), and meanwhile, a corresponding termination condition may be set for each data item, so that in the execution process of the data collection flows of each data item, only the termination condition of each data item is concerned.
For convenience of explanation, a flowchart of an acquisition scheduling method for a target acquisition data item is shown in fig. 2a, and in this embodiment, a data acquisition process for one acquisition data item is described in detail by taking data acquisition for the acquisition data item as an example.
As depicted in FIG. 2a, the method includes three flow branches S210-S220, S230-S240, and S250-S260, which are executed in parallel.
S210, sequentially acquiring a target low-pressure centralized meter reading device according to the acquisition sequence of each low-pressure centralized meter reading device recorded in an acquisition sequence table;
s220, after the operation of collecting the target collecting data items from the target low-pressure centralized meter reading equipment is executed, updating the target collecting completion rate matched with the target low-pressure centralized meter reading equipment, and returning to S210.
S230, detecting whether the target acquisition completion rate reaches an acquisition completion rate threshold corresponding to the target low-voltage centralized meter reading equipment in real time, if so, executing S240; otherwise, execution returns to S230.
S240, the operation of sequentially acquiring one target acquisition data item according to the order of the priority levels in the acquisition parameter configuration information from high to low is executed again, so that the acquisition of the target acquisition data item of the next priority level is started.
In an optional implementation manner of this embodiment, the condition for starting collection of the collected data item with the highest priority is unconditional; the starting collection condition of the collection data items with other priorities is the set collection completion rate threshold of the collection data items with the previous priority.
S250, detecting whether a termination condition corresponding to the target acquisition data item is met in real time, if so, executing S260; otherwise, execution returns to S250.
And S260, ending the continuous acquisition of the target acquisition data item meeting the termination condition.
Specifically, the method detects whether each collected data item meets a termination condition in real time in the process of executing the operation of respectively collecting the matched collected data items from each low-pressure centralized meter reading device according to the collection sequence of each low-pressure centralized meter reading device recorded in the collection sequence table aiming at each collected data item, and finishes the continuous collection of the collected data items meeting the termination condition.
When data acquisition of one or more acquired data items is carried out for each low-pressure centralized meter reading device, whether each acquired data item meets an acquisition termination condition or not needs to be detected in real time, and if so, continuous acquisition of the acquired data item is ended; otherwise, continuing to collect. The acquisition termination condition may include setting that an overall acquisition duration of the acquired data item exceeds a preset acquisition waiting duration threshold, and a new acquisition time point arrives.
In an alternative implementation of this embodiment, the termination condition may include: aiming at the situation that the total acquisition time length of the set acquisition data item exceeds a preset acquisition waiting time length threshold;
correspondingly, the method further comprises the steps of:
and counting the total acquisition time length of each acquisition data item in real time in the process of executing the operation of respectively acquiring the matched acquisition data items from each low-voltage centralized meter reading device according to the acquisition sequence of each low-voltage centralized meter reading device recorded in the acquisition sequence table aiming at each acquisition data item.
Further, in S250, it may be determined whether the data acquisition process for the target acquisition data item needs to be terminated by detecting whether the overall acquisition duration with the target acquisition data item exceeds the acquisition latency threshold.
In another alternative implementation of the present embodiment, the termination condition includes: arrival of new acquisition time points. The arrival of the new collection time point means that the collection data item can reach the target collection completion rate threshold matched with the low-voltage centralized meter reading equipment in the corresponding collection data period, or can not reach the target collection completion rate threshold. But when a new acquisition time point arrives, the continued acquisition of the acquired data item is ended.
According to the technical scheme, collected parameter configuration information is formed by responding to a parameter configuration instruction of a user; forming an acquisition sequence table according to the historical data acquisition condition of each connected low-voltage centralized meter reading device; when the acquisition conditions of all the low-voltage centralized meter reading equipment are met, sequentially acquiring a target acquisition data item according to the order of the priority levels in the acquisition parameter configuration information from high to low; and respectively acquiring target acquisition data items from the low-voltage centralized meter reading devices according to the acquisition sequence of the low-voltage centralized meter reading devices recorded in the acquisition sequence table, and executing the operation of sequentially acquiring one target acquisition data item from the high-to-low priority sequence in the acquisition parameter configuration information again until the acquisition process is finished. According to the data acquisition method and device, the dynamic switching of the acquired data items and frequencies is realized according to the properties and the acquisition conditions of different data, the problems of multiple groups of data acquisition and flexible data configuration according to different requirements and scenes are solved, the acquisition optimization is realized, and the acquisition success rate is improved.
