For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In addition, the term "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In this context, unless otherwise specified, the term "/" generally indicates that the associated object is an "or" relationship.
The current data transmission between the power grid system and the ammeter is generally carried out by adopting one mode of power line carrier and wireless communication, or alternatively, the two modes are used, namely, the data transmission is realized by still using a single communication link in the data transmission process. Because the single communication link used at present realizes the data transmission between the power grid system and the ammeter, a check mechanism is arranged in the data transmission process in order to ensure the reliability of the data transmission. The checking mechanism is used for checking whether the data is successfully transmitted, and if the data fails to be transmitted without passing the check, the data needs to be retransmitted. The checking mechanism also takes a part of the time, resulting in low data transmission efficiency of the single communication link. The application adopts a plurality of communication links to carry out data transmission, the plurality of communication links adopt a checking mechanism during transmission, when one communication link passes through the checking mechanism, the integrity of the data transmission can be ensured, the time occupied by error retransmission of the checking mechanism is reduced, and the data transmission efficiency is improved.
Embodiments of the application are described in further detail below with reference to the drawings.
Fig. 1 is a schematic diagram of an exemplary operating environment according to an embodiment of the present application, where the operating environment includes an electric meter, a concentrator, and a manager, where the manager is integrated with a power grid system for managing data of the electric meter, and one manager may be communicatively connected to a plurality of concentrators by using power line carrier communication and/or wireless communication, and each concentrator may also be communicatively connected to a plurality of electric meters by using power line carrier communication and/or wireless communication, where the wireless communication may be a 4G communication network connection. The concentrator is used for collecting the ammeter data of a plurality of ammeter connected with the concentrator and uploading the received ammeter data to the manager.
In order to improve the transmission efficiency of a communication link between an electricity meter and a concentrator (or a concentrator and a manager), an embodiment of the present application provides an electricity meter data transmission method, which is performed by the electricity meter (or the concentrator) in fig. 1, and the main flow of the method is described as follows.
Step S101: the service request and the operating states of a plurality of communication links of the ammeter are obtained.
Specifically, the service request may be a request sent by the power grid system for obtaining data, or a request sent by some fixed mechanism in the electric meter for sending data. The fixed mechanism comprises the steps of uploading ammeter data at fixed time, reporting faults, reporting power failure and the like. The service request includes a request for acquiring data of a specified electric meter, a system upgrade request, a time calibration request, and the like.
And the working state of a plurality of communication links of the ammeter is used for indicating whether a certain communication link can normally communicate, if so, the working state is normal, and if not, the working state is abnormal. In the embodiments provided herein, the plurality of communication links is two communication links including a power line carrier link and a wireless communication link. In other embodiments, the plurality of communication links may include other communication links such as fiber optic communication, microwave communication, and the like, in addition to the power line carrier link and the wireless communication link.
Step S102: at least two available communication links are determined based on the operating states of the plurality of communication links.
Specifically, the working states of a plurality of communication links are sequentially judged, and when the working states of the communication links are normal, the communication links are available communication links. In the embodiments provided herein, the available communication links are power line carrier links and wireless communication links.
Step S103: and sending the ammeter data corresponding to the service request according to the service request and the available communication link.
Specifically, the service request includes a request level and a service requirement, and the service requirement represents what data is needed, for example, electricity consumption data of 10 specified electricity meters. The request level indicates that the service request has high or low requirements on data transmission, for example, some service requests have high requirements on data transmission efficiency, and some service requests have high requirements on data accuracy. The request level of a service request is related to the event that triggered the service request. For example, due to a service request triggered by a regional outage, the request needs to be fast and accurate for event and/or data transmission, and the service request has the highest request level, which is the first request level. For another example, a time-triggered time-aligned service request, such a service request, too, requires a fast and accurate completion of the data transmission. For a service request with meter reading at a timing of a minute level, the request level of the service request is medium, namely the second request level, because the data volume is large and the efficiency requirement for data transmission is relatively low. For other daily service requests, the data volume is not large, and at the same time, no service request with higher requirement on the data transmission speed exists, and the service request has the lowest request level, namely the third request level.
And when the request grade of the service request is higher than a preset grade, respectively using a plurality of available communication links to send the ammeter data corresponding to the service request. When the request level is the first request level, the power line carrier link and the wireless communication link are used for transmitting the data of the ammeter, when two or more links are used for transmitting the same data at the same time, the two communication links adopt a checking mechanism, when one communication link passes through the checking mechanism, the integrity of the data transmission can be ensured, even if the other communication link does not pass through the checking mechanism, the data transmission cannot be influenced, and the time occupied by error retransmission of the checking mechanism is reduced. The application adopts a plurality of links to simultaneously transmit data, thereby ensuring the integrity of data transmission to a certain extent and improving the transmission efficiency of data.
When the request level of the service request is equal to a preset level, dividing the ammeter data corresponding to the service request into multiple parts corresponding to the number of the available communication links according to the communication state of the available communication links, and respectively transmitting the multiple parts of ammeter data corresponding to the service request by using the multiple available communication links. The communication state is used for reflecting the data transmission condition of the communication link, and the data transmission speed of the communication link can be obtained according to the communication state.
Specifically, when the request level of the service request is the second request level, the communication state of the available communication links is obtained, the data transmission speed of each available communication link is obtained according to the communication state, the electric meter data corresponding to the service request is divided into a plurality of parts according to the data transmission speed, the ratio of the data quantity of the plurality of parts of data is the same as the ratio of the data transmission speed, and then each available communication link transmits one part of electric meter data corresponding to the available communication link.
For example, a data transmission speed of the power line carrier link and a data transmission speed of the wireless communication link are acquired, wherein the data transmission speed of the power line carrier link is 10 megabits per second (megabits per second, mbps), the data transmission speed of the wireless communication link is 1 megabit per second, the electric meter data corresponding to the service request is divided into two parts, the ratio of the data amounts of the two parts is 1/10, the data with the data amount ratio of 1 is transmitted through the wireless communication link, and the data with the data amount ratio of 10 is transmitted through the power line carrier link.
When the request level of the service request is equal to the preset level, the data transmission is performed by adopting the differential data mode, a target communication link can be determined according to the communication state of the available communication link, and the electric meter data corresponding to the service request can be sent by using the target communication link.
The communication state further includes a packet loss rate and a bandwidth, and the process of determining the target communication link includes: and comparing the packet loss rates of all available communication links, selecting the communication link with the smallest packet loss rate as a target communication link, and when more than one communication link corresponds to the smallest packet loss rate, comparing the bandwidths of the communication links, and selecting the communication link with the smallest packet loss rate and larger bandwidth as the target communication link. When more than one communication link with the smallest packet loss rate and larger bandwidth is adopted, the communication link with the largest transmission data is selected as the target communication link. And then transmitting the ammeter data corresponding to the service request through the target communication link.
And when the request level of the service request is lower than a preset level, sending the ammeter data corresponding to the service request by using a designated link in the available communication links. And presetting a link priority for the service request with the request level of the third request level, and determining a designated link according to the priority of the available communication link, namely when the request level of the service request is the third request level, taking the link with the highest priority in the available communication link as the designated link to finish the transmission of the ammeter data.
