Description
Technical Field
The invention relates to the technical field of electric energy meter communication, in particular to an electric energy meter communication method and system based on subsequent frame dynamic registration.
Background
China will fully enter into the '2.0 times of power grid', and the full coverage of the intelligent ammeter is realized. Different from the traditional electric energy meter, the intelligent electric energy meter has the most basic metering function, the function and the data quantity are exponentially increased, and very high requirements are provided for data acquisition. The high efficiency, accuracy and timeliness of the data uploaded by the electric energy meter play a vital role in the stability of the whole system. But as the power meter function and data accuracy expand, the data length increases. If the base power is 4 bytes, 4 rates, then the read forward active power length is 20 bytes (sum rate). The new increased precision power is 8 bytes and 12 rates, then the combined active power is 104 bytes (sum rate). The electric energy meter 698 protocol 20 standardizes that frozen data to be obtained after being taken out of the desk requires that basic electric energy be upgraded into high-precision electric energy, and collected data is multiplied.
One application layer data frame has a maximum APDU length of 2000, while the maximum APDU of data transmission does not exceed 512, and the carrier channel as the main communication channel is more than 255. Link layer framing transmissions are required. The electric energy meter 698 protocol requires: each physical port maintains an independent link layer framing (each framing fragment is not self-resolvable), requiring at least 2000 bytes per channel. The current electric energy meter can support channels with 2 channels 485, 1 channel infrared, 1 channel carrier, 5 channels Bluetooth, two or more expansion modules and the like. If at least 11×2000=22000 space is required for supporting, the space required is very large, so that a high-specification singlechip is required to meet the communication requirement.
Consider the case where there is substantially no simultaneous communication and simultaneous operation of subsequent frames using a scene. The highest frequency of use is that the main station reads frozen data through the carrier channel and the expansion module, and the other channels have low frequency of use. If each channel is opened, the product cost is increased, and the lower utilization rate can cause the waste of the space of the singlechip.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In addition, the technical features of the different embodiments of the present invention described below may be combined with each other as long as they do not collide with each other.
The embodiment of the invention provides an electric energy meter communication method based on subsequent frame dynamic registration, wherein the communication process of the electric energy meter relates to two-way communication of a client and a server, and the method provided by the embodiment of the invention is applied to a server side, as shown in fig. 1, and specifically comprises the following steps:
step S1: after the electric energy meter is electrified, initializing a preset number of communication channels and a preset number of subsequent frame storage spaces into an unregistered state.
Specifically, in the embodiment of the present invention, as shown in the dynamic routing topology diagram of fig. 2, channels that can be supported by the electric energy meter include a carrier communication channel, a 485 communication channel, an infrared communication channel, a bluetooth communication channel, a metering module communication channel, and an expansion module communication channel, where the expansion module includes a load identification module and a quality monitoring module. The invention selects one carrier communication channel and two 485 communication channels with highest frequency, but is not limited to this. Three subsequent frame memory spaces are correspondingly arranged, and each memory space is a 2100-byte RAM space, but the method is not limited to the 2100-byte RAM space. Meanwhile, the embodiment of the invention configures a channel timer for each communication channel. After the electric energy meter is electrified, the passing channel and the storage space of the subsequent frame are set to be in an unregistered state, and the method comprises the following steps:
the specific initialization flow is shown in fig. 3, and is described as follows by setting temporary variables to traverse all communication channels and the storage space of the subsequent frames:
(1) Powering up and initializing, and calling the flow;
(2) The judgment number of the temporary variable is given an initial value of 0;
(3) If the judgment number is more than or equal to 3, jumping to (6);
(4) The channel number is initialized to 0xFF, the subsequent frame number is initialized to 0xFF, and the channel timer is initialized to 0;
(5) Judging the number++, and jumping to (3);
(6) And (5) ending.
In the embodiment of the invention, the first preset code and the second preset code are both set to 0xFF, which represents an unregistered state, but is not limited thereto.
Step S2: and after the first frame of the data frame transmitted by the communication channel is monitored, dynamically pairing and registering the communication channel and the subsequent frame storage space according to the registration state of the communication channel and the subsequent frame storage space and the preset emergency importance priority of the data frame.
Specifically, in the embodiment of the present invention, after data acquisition, the client sends the data to the link layer of the server, and when the server needs to communicate with the client, the server sends the application layer data to the link layer, so that the present invention realizes the transmission of the frame data by performing the subsequent frame dynamic registration on the link layer, as shown in fig. 4. When any party needs to perform data transmission and the data frame exceeds the maximum transmission size and needs to perform frame division transmission, the frame division is issued to a link layer of a server, and after the first frame of the data frame is monitored, dynamic pairing registration is performed, wherein the registration process is as follows:
1. judging the registration state of the communication channel according to the channel number, and judging the registration state of the storage space of the subsequent frame according to the subsequent frame number;
2. if the communication channel and the storage space of the subsequent frame are in an unregistered state, the communication channel and the storage space of the subsequent frame are paired and registered according to the time priority;
3. if all the communication channels and the storage space of the subsequent frames are in the registered state through traversal, sequentially comparing the data frames in the communication channels with the data frames in the storage space of the subsequent frames according to the preset emergency importance priority;
4. if the priority of the data frame in the communication channel is higher than the priority of the data frame with the lowest priority in the storage space of the subsequent frame, the communication channel and the storage space of the subsequent frame with the lowest priority are paired and registered, otherwise, the pairing and registration are not performed.
According to communication expectations and success rates, grading the data frames from three dimensions of emergency priority, importance priority and time priority, presetting the emergency importance priority, wherein the priority adopts a sorting mode from small to large, the 0 level is highest, and gradually increases to be lower and lower, as shown in the following table:
the emergency priority and the importance priority are integrated to obtain the emergency importance priority, wherein the high half byte is the emergency, and the low half byte is the importance, as shown in the following table:
when a plurality of data frames are transmitted, processing is performed according to the time priority, and registration is performed first. And if the storage spaces of the subsequent frames are all registered, screening and sorting are carried out according to the priority of the emergency importance, the lowest priority is cancelled, and the registration of high priority is carried out. When the pairing registration is performed, the subsequent frame storage space can be used for the pairing registration of each communication channel in an unregistered state. The time priority and the emergency importance priority are used for dynamic registration, so that the daily communication function requirement can be met, and a small amount of resources are used for exchanging the maximum value. The embodiment of the invention can also expand or compress the channels according to the actual demands of the communication channels, and determine the number of the storage spaces of the subsequent frames based on the number of the channels, wherein each communication channel supports one subsequent storage space.
Further, the channel timer is set to a preset time and communication timing is performed while registration is performed. The specific registration flow is shown in fig. 5, and by setting temporary variables to traverse all channels, selecting an idle communication channel and performing pairing registration on the channel and a storage space of a subsequent frame, the flow is described as follows:
(1) When the application layer frames or the link layer frames are received, the flow is called;
(2) The judgment number of the temporary variable is given an initial value of 0;
(3) If the judgment number is more than or equal to 3, jumping to (7);
(4) If the channel number of the judgment number is not 0xFF, jumping to (3);
(5) Registering a channel number (equal to the issuing channel number), registering a subsequent frame number (equal to the judging number), and setting a channel timer to 10;
(6) Judging the number++, and jumping to (3);
(7) And (5) ending.
In the embodiment of the invention, the channel timer is set to 10, which represents the timing time of 10s, but is not limited thereto.
Step S3: and storing the first frame and the subsequent frame of the data frame into the paired subsequent frame storage space for communication, and canceling the communication channel and the paired subsequent frame storage space to be in an unregistered state when the data transmission is finished.
Specifically, in the embodiment of the invention, after the communication channel and the storage space of the subsequent frame are paired and registered, the first frame and the subsequent frame of the data frame are all stored in the paired subsequent frame storage space. In the data transmission process, the channel timer performs communication timing according to preset timing time, checks the channel timer every second, checks whether the timing is finished, and a specific timing processing flow is shown in fig. 6, and the flow is described as follows:
(1) Every second, calling the flow;
(2) The judgment number of the temporary variable is given an initial value of 0;
(3) If the judgment number is more than or equal to 3, jumping to (7);
(4) If the timer of the judgment number is not more than 0, jumping to (3);
(5) Channel timer-;
(6) If the timer of the present judgment number is equal to 0, the channel number (equal to 0 xFF) is logged out, and the subsequent frame number (equal to 0 xFF) is logged out;
(7) And (5) ending.
In the embodiment of the invention, when the data transmission is finished or the timing is finished, the corresponding communication channel and the subsequent frame storage space are logged out to be in an unregistered state, namely, the channel number of the communication channel is reset to be a first preset code, and the subsequent frame number of the subsequent frame storage space is reset to be a second preset code. For example, in the embodiment of the present invention, the first preset code and the second preset code are set to 0xFF again, and the unregistered state is restored. In addition, when dynamic registration is performed according to the priority of emergency importance, the registration is performed again after the cancellation is performed. The specific logout flow is shown in fig. 7, and the flow is described as follows:
(1) The judgment number of the temporary variable is given an initial value of 0;
(2) If the judgment number is more than or equal to 3, jumping to (6);
(3) If the channel number of the judgment number is registered, jumping to (5);
(4) Judging the number++, and jumping to (2);
(5) Deregistering the channel number (equal to 0 xFF), deregistering the subsequent frame number (equal to 0 xFF), and setting the channel timer to 0;
(6) And (5) ending.
The flow of the whole communication processing data frame is shown in fig. 8, and includes a two-way communication process, which is specifically described as follows:
(1) When in communication, the flow is called;
(2) Judging whether the frame is divided, if not, jumping to the step (5);
(3) Judging whether the frame is the first frame or not, if not, jumping to the step (8);
(4) Performing subsequent frame registration, and jumping to (12);
(5) Judging whether the subsequent frame is acquired or not, if not, jumping to (10);
(6) Judging whether the subsequent frame is finished or not, if not, jumping to (11);
(7) Logging off, and jumping to (12);
(8) Judging whether the data is received completely or not, and jumping to the step (11) if the data is not received completely;
(9) Logging out;
(10) Application layer data processing, jumping to (12);
(11) Processing link layer data;
(12) Judging whether framing is needed or not, and jumping to the step (14) if not;
(13) Registering;
(14) Organizing the data frames;
(15) And (5) ending.
According to the electric energy meter communication method based on the subsequent frame dynamic registration, after the electric energy meter is powered on, if the first frame of the transmitted data frame is monitored, the communication channel and the subsequent frame storage space are dynamically paired and registered according to the registration state of the communication channel and the subsequent frame storage space and the preset emergency importance priority of the data frame, communication timing is carried out based on the channel timer, and the communication channel and the paired subsequent frame storage space are cancelled to be in an unregistered state after communication or timing is finished. The invention uses the following frame dynamic registration mechanism, each channel has low coupling degree, can ensure reasonable and efficient resource allocation on the basis of meeting the daily function requirement, and has high expandability, can expand or compress the communication channel according to the actual requirement, and has extremely small code modification amount.
