Detailed Description
The present application is further described below with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present application is not limited thereby.
Fig. 1 is a schematic flow chart illustrating steps of an intelligent electricity consumption data acquisition and uploading method based on a repeater according to the present invention. As shown in fig. 1, a first aspect of the present invention relates to an intelligent electricity consumption data collection and uploading method based on a repeater, wherein the method includes steps 1 to 3.
It can be understood that the intelligent electricity data acquisition and uploading method is suitable for various systems with three-layer network structures. The three-layer network structure described herein is a network structure that includes a master station, relays, and terminals. Typically, a plurality of relays are connected to a master station, and each relay device is connected to a plurality of terminals. In this network configuration, the master station may send data requests to the relays and the terminal devices in a broadcast manner, and after responding to the requests, each eligible terminal device may return data to the master station.
In an embodiment of the present invention, the network structure may be applied to a power system. The main station is used as a station for processing the electricity consumption data, the terminal can be an intelligent electricity consumption data acquisition terminal, such as an intelligent electric meter, a common electric energy meter and the like, and the relay can correspond to the intelligent electric meter and be configured as a concentrator for acquiring the data of the intelligent electric meter.
Specifically, in an embodiment of the present invention, a plurality of electric energy meters may be combined into an electric energy meter group, where each group of electric energy meters is connected to the same concentrator. The electric energy meter can be used as a household entrance port to collect various household electric load identification data, such as voltage, current, user electric quantity, abnormal events and the like. Meanwhile, the electric energy meter can support a time-sharing metering mode to send data to the concentrator through power carrier waves after the data are collected.
Step 1, the intelligent electricity consumption data acquisition terminal circularly sends data requests to delete pre-acquired electricity consumption data at preset time intervals based on a repeater.
In the invention, before the data acquired by the intelligent power consumption data acquisition terminal is sent to the repeater, the data stored in the intelligent power consumption data acquisition terminal needs to be preprocessed. Specifically, when the intelligent power consumption data receives a data request each time, the intelligent power consumption data judges the request and responds to whether to respond to the request. If the intelligent power consumption data acquisition terminal determines that the request needs to be responded, the power consumption data of the user side connected with the equipment needs to be acquired again. In order to accurately collect the electricity utilization data in the current time period and reply the data without redundancy to the repeater and the electricity utilization data processing main station, before collecting the data in the current time period, the deletion operation of the data collected in the last time period stored in the local terminal is required. In this way, the data collected in the previous time period is not repeatedly transmitted, so that data redundancy is not caused. Therefore, the electricity consumption data collected in advance in step 1 of the present invention is only used for explaining the data collected in the previous time period, and is not the data content collected in the present time period.
In addition, because the intelligent user data acquisition terminals are various in types and quantity and have various characteristics in network connection modes, the data acquisition process of the intelligent user data acquisition terminals and the data transmission process of the intelligent user data acquisition terminals to the repeater do not have high reliability. For example, in the prior art, when the data acquired in the previous time period is not timely transmitted to the relay, the terminal may simultaneously transmit the data acquired in the two different time periods to the relay in the next time period. The repeater then forwards the data to the master station. Because the quantity of the collected data is huge, not all data items can cover the time stamp, so that the main station cannot accurately obtain the collection time of the electricity consumption data although receiving the electricity consumption data, and the main station is easy to make mistakes in the process of analyzing and processing the data. For another example, in the prior art, in order to prevent data from not being transmitted reliably, data acquired at one time may be transmitted multiple times in multiple time periods, which also easily causes confusion of the master station about the time of data acquisition.
In the application, the data stored in the local terminal is deleted before the acquisition operation is executed each time, and then the acquisition and transmission are performed. In this way, substantial data redundancy is avoided.
Specifically, the terminal receives two different requests from the relay, one is a data request and the other is a repeat request.
The first data request is a request which is automatically sent to the terminal by the repeater after the first preset time period is finished. While the second type of request is typically a remedy to prevent the unsuccessful receipt of data after the first type of data request is sent. Therefore, the repeat request is typically issued a short interval after the first data request. The terminal determines a duplicate request in order to prevent duplicate data transmission.
Specifically, after receiving a data request in the next time period, the terminal will execute a deletion operation and re-collect and transmit power consumption data. After receiving the repeat request, the terminal determines whether an acknowledgement signal sent from the repeater is received in the current time period. The confirmation signal is a signal that the repeater notifies the terminal that the data request it sent has been responded to with the data sent. If the terminal judges that the confirmation signal is received, the terminal does not send data to the repeater again, and the local data does not need to be deleted at the moment. If the terminal does not receive the confirmation signal, the local data is deleted, and the operation of collecting the data is executed.
It should be noted that there is a special case, and in general, the terminal can receive the data request in each time interval and effectively feed back the power consumption data. Thus, even if the repeater transmits a repeat request, the terminal does not feed back. However, when the data request of the relay in the current period is not transmitted to the terminal, the terminal can receive only the repeated request of the current period. Then, according to the repeated request, the terminal also needs to delete the power consumption data collected in advance, that is, the data collected in the previous time period.
For the situation that the terminal receives the data request and the repeated request in the current time period, the terminal deletes the pre-collected data in the data request stage, so that the repeated request does not need to be deleted again. In the case where the terminal receives the data request, but does not successfully transmit the power consumption data to the relay and then receives the repeat request, the processing procedure of the terminal for repeatedly transmitting the power consumption data of the current time period will be specifically described in step 2 and step 3.
And 2, after the pre-collected power utilization data are deleted, the intelligent power utilization data collection terminal collects the power utilization data and responds to the request of the repeater to send the power utilization data, wherein the intelligent power utilization data collection terminal judges based on repeated requests sent by the repeater and confirms whether to collect and send the power utilization data again.
According to the invention, after the local electricity consumption data are deleted, the intelligent electricity consumption data acquisition terminal acquires the data according to the request and sends the data.
Preferably, step 2 further comprises: step 2.1, after the intelligent electricity consumption data acquisition terminal receives a data request of a response repeater, the acquired electricity consumption data are sent to the repeater; step 2.2, after receiving the electricity utilization data sent by the intelligent electricity utilization data acquisition terminal, the repeater feeds back a receiving confirmation signal to the intelligent electricity utilization data acquisition terminal; step 2.3, if the intelligent electricity consumption data acquisition terminal receives the confirmation signal, the repeated request sent by the repeater is not responded; and if the intelligent power consumption data acquisition terminal does not receive the confirmation signal, the power consumption data of the acquisition time period corresponding to the base data request is deleted after the repeated request sent by the repeater is responded, and the power consumption data is acquired again and sent to the repeater.
Specifically, in the invention, the intelligent electricity consumption data acquisition terminal responds to the data request of the repeater and sends data, and after the repeater receives the data, the data is fed back and confirmed. Thereby, the data request and the data reply for one period of time are completed. After the terminal has confirmed that the data is successfully transmitted, it is not necessary to respond to the repeat request again in the current time period. The terminal will not re-respond to the request and perform the same operation procedure until the next time period starts.
However, the reliability of the collection of electricity usage data is not so high due to network connectivity and network transmission problems. Therefore, a problem often arises in that a data request is not successfully responded to. In this case, the repeater cannot feed back the acknowledgement signal to the terminal, and therefore, the terminal needs to re-acquire and feed back data after receiving the repeat request.
It should be noted that, in the present invention, the terminal may collect the power consumption data based on the data request, and send the data corresponding to the collection time period based on the data request. However, in the process of the terminal transmitting data to the repeater, a communication failure may occur. In this case, when the repeater does not receive the power usage data fed back by the terminal based on the data request, a repeat request is issued. And the terminal can not directly feed back the data before the short interval collected for the data request for the repeated request. Even if the terminal is used for repeated requests, the terminal still acquires data again and feeds back the data after deleting internal data. Internal data here refers to data collected for a data request.
This is because the format of the re-request is similar to the repeat request sent by the repeater when the network card is present in the electric energy meter in the prior art or the data transmission time is too long. If the terminal does not delete the internal data for re-acquisition, the time stamp of the acquired data is difficult to ensure accuracy under the condition that the repeater does not perform any data processing. If the data needs to be processed, the storage and calculation pressures of the repeater are consumed. It can be seen that if the internal data is not deleted for re-collection, the following problems may occur: the terminal cannot determine whether to acquire data before or after 3 minutes based on the data content uploaded by the repeated request. This causes the system to be inaccurate when it subsequently processes the data.
Therefore, the method realizes the effect of data instant acquisition, and uploads the data acquired at the current time according to the accurate time of each request. When the subsequent system processes the data, the approximate processing can be performed based on all the data, or the accurate analysis can be performed based on the accurate data. In addition, in the invention, in order to prevent the problems possibly occurring in the data analysis process caused by the inaccuracy of the data acquisition time, the requirement on the comprehensive degree of the data is abandoned.
It will be appreciated that the repeat request is still distinguished from the data request in that the repeater does not send an acknowledgement signal to the terminal whether or not the repeater receives power usage data based on the repeat request.
Fig. 2 is a timing chart of power consumption data acquisition and uploading in the intelligent power consumption data acquisition and uploading method based on the repeater of the present invention. A time sequence of successful response to repeated requests after unsuccessful response to a first data request for power usage data acquisition is shown in fig. 2.
Preferably, the repeater sends a data request to the intelligent power consumption data acquisition terminal based on a first preset time interval; and the repeater sends a repeated request to the intelligent electricity utilization data acquisition terminal after a second preset time interval sent by the data request.
Generally, the first and second preset time intervals are both set in advance by the system. For example, the master station may set an acquisition interval for the electricity consumption data and send the interval to each relay station. After receiving the information, the relay station configures each intelligent electricity consumption data acquisition terminal accessed under the relay station based on the same interval.
Preferably, the first preset time interval is greater than the second preset time interval.
Since the second time interval is used for executing the repeat request, the value thereof must be smaller than the first preset time interval. And, generally speaking, the second time interval is much smaller than the first time interval.
Preferably, the first predetermined time interval is 15 minutes and the second predetermined time interval is 3 minutes.
In an embodiment of the present invention, the first predetermined time interval may be set to 15 minutes, and the second predetermined time interval may be set to 3 minutes. In the invention, the second time interval is not set to be very small, so that the problem of data loss caused by the fact that data cannot be successfully acquired or successfully uploaded to the master station in two times when the network cannot be recovered in time is solved.
In addition, in order to ensure synchronization and consistency of time in the network system. The electricity consumption data processing master station can actively send time synchronization information to the intelligent electricity consumption data acquisition terminal and the repeater so as to realize the consistent time synchronization of all devices in the whole system.
Preferably, the electricity consumption data processing master station regularly sends time setting information to the intelligent electricity consumption data acquisition terminal through the repeater, and sends the time setting information to the intelligent electricity consumption data acquisition terminal before electricity consumption data are acquired for the first time; the intelligent electricity data acquisition terminal executes synchronous time setting operation based on the time setting information.
Fig. 3 is a schematic diagram of device time synchronization in the intelligent power consumption data acquisition and uploading method based on the repeater. Specifically, as shown in fig. 3, the master station may manage all terminals through the repeater, and after receiving the time tick information, the terminals accumulate the information of the clock on the local chip and implement time tick.
In the present invention, in order to ensure that the data acquired by the system are time-synchronized, for example, even if the data acquired for the first time is accurate, the time synchronization should be performed on the data before the data is acquired for the first time.
Preferably, the electricity consumption data processing master station sends time setting information to the intelligent electricity consumption data acquisition terminal based on a third preset time interval; the third preset time interval is N times of the first preset time interval, wherein N is more than or equal to 50.
In an embodiment of the present invention, the third preset time interval is 24 hours a day, and by performing time synchronization once in a 24-hour time period, it is possible to prevent a time error of data from increasing due to an excessively large time synchronization interval. And a third preset time interval is set based on the first preset time interval, so that the accuracy of the data timestamp can be better realized according to the frequency requirement of the system for acquiring data. By the method, not only can the time setting be prevented from being too frequent, but also the time setting frequency can be ensured to fully meet the requirement of data acquisition accuracy.
In the invention, the operation of executing time synchronization or deleting on the data is realized based on the load identification algorithm module integrated in the intelligent power utilization data acquisition terminal.
Preferably, the power utilization data is load identification data acquired by an intelligent power utilization data acquisition terminal; the load identification data comprises power utilization voltage, power utilization current, user power and abnormal power utilization events.
As described above, the data collected in the present invention may include various electricity usage indicators. Such as the commonly used voltage, current, power, etc., and abnormal electricity consumption information summarized according to the abnormal electricity consumption event. Specifically, the abnormal electricity utilization events in the present invention may include indoor short circuit, indoor large current, indoor current surge, and the like. For example, when an electric bicycle is charged by entering a home, the electric energy meter can collect the occurrence of a high-current event in the home at the moment and send the event to the master station as a piece of collected information. The main station can predict the load in advance according to the power utilization conditions of all the terminals, and the appropriate power supply is considered.
In addition, a carrier communication module may be embedded in the terminal. In particular, the carrier communication module may be used to perform transmission and reception of carrier signals, processing of communication protocols, assembly and maintenance of carrier networks, and adaptation functions of carrier communication.
After the terminal collects the data, the information can be sent to the repeater through the power carrier wave in a time-sharing metering mode. The repeater, acting as a relay station, may forward the information to the master station.
And 3, after receiving the electricity utilization data, the repeater forwards the electricity utilization data to the electricity utilization data processing master station in real time.
In an embodiment of the present invention, the repeater may be a concentrator. The concentrator is used for completing communication with the terminal, reading information in a terminal electric meter, communicating with the main station through 4G, and managing and maintaining the electric energy meter.
Preferably, the intelligent electricity consumption data acquisition terminal transmits the electricity carrier data obtained after encoding and modulating the electricity consumption data to the repeater based on power carrier communication; the repeater modulates the power carrier data based on the 4G communication system and transmits the data to the power consumption data processing main station.
It can be understood that, the repeater in the present invention does not have redundant data processing and computing functions, and therefore, after receiving the power carrier data, the repeater does not demodulate and decode the data, but directly modulates the data onto the channel frequency band of the 4G communication system, and realizes continuous transmission, so as to complete the repeating function.
The concentrator can be used for finishing communication with a main station as one type of the repeater, and communication with a plurality of terminal electric energy meters is realized through a 4G communication system. In addition, the concentrator can manage and maintain the electric energy meter, and collect load identification data in the electric energy meter in a power carrier communication mode.
Specifically, in the invention, in order to integrate the data processing steps at the master station end, the meter reading mode of the concentrator is improved. Because the redundant data are deleted in time according to different time periods and conditions on the terminal side, the concentrator can collect all data from the terminal without processing the data from the terminal. By the method, the workload of the concentrator can be greatly reduced, so that the concentrator only executes the function of transferring data, redundant data are reduced, and the speed of forwarding data by the concentrator is increased. Meanwhile, various errors of the concentrator in the data processing process are avoided.
Preferably, the repeater acquires the equipment number and the equipment model of the intelligent power consumption data acquisition terminal in advance, and acquires the power consumption data based on the equipment number and the equipment model.
In the present invention, the concentrator may store all the parameters related to the electric energy meters communicating with the concentrator, such as the device number, the device model, and the like. By comparing the parameters, the legal device approved by the concentrator can be effectively logged into the concentrator. In this way, illegal access by illegal devices can be avoided and counterfeit or illegal data can be mixed into the data transmitted by the concentrator to the primary station. In this way, the security of data acquisition is improved.
The method for the repeater to pre-acquire the equipment number and the equipment model of the intelligent power consumption data acquisition terminal mainly comprises two methods. One is to obtain, for example, the device number by the system, and issue the device number to each subordinate intelligent electricity data acquisition terminal. And the other method is to acquire the equipment signals from the intelligent electricity utilization data acquisition terminal and upload the equipment signals to the system to realize synchronization.
Preferably, the power consumption data processing master station analyzes and calculates the received power consumption data to obtain the information of the start-stop time of the electric appliance, the energy consumption level of the electric appliance and the use rule of the electric appliance.
In the invention, the master station can read the power utilization data from the repeater and extract the electric appliance working characteristics in the power utilization data by adopting signal analysis and machine learning algorithm, thereby acquiring the information of start-stop time, energy consumption level, use rule and the like of relevant electric appliance equipment. In the invention, the characteristics can be extracted by adopting a correlation method in the prior art, and the correlated rule information can be generated.
The electrical appliances described herein may include some common household electrical appliances, and the usage rules may include waveform information of current, voltage, power, and the like of various electrical appliances during the usage process. For example, when the electric bicycle performs household charging, the current information collected by the electric energy meter is instantly and greatly improved. The master station can know the charging time of the electric bicycle users by analyzing the information, and can perform early warning of the load of the power grid and change power generation and distribution strategies and the like when the use habits of a large number of users are similar, such as charging at work hours and the like.
Fig. 4 is a schematic structural diagram of an intelligent power consumption data acquisition and uploading system based on a repeater. As shown in fig. 4, a second aspect of the present invention relates to an intelligent electricity data collecting and uploading system based on a repeater. The system comprises an intelligent power consumption master station, a plurality of relays in communication connection with the intelligent power consumption master station, and a plurality of intelligent power consumption data acquisition terminals in communication connection with each relay; moreover, the system adopts the intelligent electricity utilization data acquisition and uploading method based on the repeater to realize communication transmission and data processing.
