Detailed Description
The invention is further described below with reference to the accompanying drawings.
An IEC104 protocol processing method based on 5G communication is completed based on a master station and terminal equipment which are connected through a wireless transmission channel and slave equipment which is connected with the terminal equipment through an RS485 bus, the master station and the terminal equipment perform data interaction through an IEC104 protocol, and a 5G wireless transmission channel is adopted between the master station and the terminal equipment, as shown in figure 1.
The terminal equipment is provided with a protocol trigger frame, and the protocol trigger frame comprises a data item, trigger information corresponding to the data item, an operation module corresponding to the data item and configuration information.
The method comprises the following steps:
1.1, receiving master station data by the terminal equipment, and analyzing an IEC104 protocol;
1.2, the terminal equipment extracts the data item and generates protocol control information according to the data item and the protocol trigger framework;
1.3, configuring data items according to the protocol control information;
1.4, determining the operation sequence of each operation module according to the protocol control information;
and 1.5, the terminal equipment issues an execution command of the operation module to the slave equipment, collects data of the slave equipment and sends the executed feedback information to the master station.
In this embodiment, the data items include remote measurement, remote signaling, remote tuning commands, remote control commands, kilowatt-hour measurement, and fixed value measurement.
The operation module corresponding to the data item comprises information acquisition, telemetering acquisition, remote signaling acquisition, event acquisition, remote regulation execution and remote control execution.
The value range of the trigger information is 0-2, and the value range of the configuration information is 0-3.
Configuring the data items according to the protocol control information, and associating the trigger information with the data items, such as associating configuration information 1 with a remote control command.
When the master station transmits the commands collectively, the terminal device cannot process the commands in time, and the unexecuted commands wait in the terminal device. The traditional approach is to wait for execution in order of arrival.
In this embodiment, if there are a plurality of unprocessed data items in the terminal device, the unprocessed data items are queued according to the size of the trigger information; and when the terminal equipment is idle, preferentially processing the data item with large triggering information.
If the current item is identical to the unprocessed item, i.e. the previous command was not executed, the master station sends the same command again, in which case the terminal device only responds once, thus deleting the unprocessed or current item.
The following description will be given taking two data items of a remote control command and a remote control command as an example.
When the trigger information corresponding to the data item remote regulation command is greater than 0, the configuration information acquired by remote measurement is 1, the configuration information executed by remote regulation is 2, and the configuration information of other operation modules is 0, as shown in the following table.
Remote control protocol triggering framework
After receiving the data items sent by the master station, the terminal equipment analyzes the IEC104 protocol, extracts service data, generates protocol control information according to a remote regulation protocol trigger frame when the service data is a remote regulation command, at the moment, the remote regulation command is effectively triggered, and the remote measurement calling, the remote signaling calling, the remote control command, the electric power calling and the like of an uplink (between the master station and the terminal equipment) are all temporarily stopped to be processed, and uplink channel resources are reserved; according to the configuration information of the operation module, information acquisition, remote signaling acquisition, event acquisition and remote control execution of downlink (between terminal equipment and slave equipment) temporarily stop processing, downlink channel resources are reserved, remote regulation execution and remote measurement acquisition are preferentially executed, and after execution is finished, current trigger information and configuration information are removed, and normal operation is recovered.
When the trigger information corresponding to the data item remote control command is greater than 0, the configuration information acquired by remote control is 1, the configuration information executed by remote control is 2, and the configuration information of other operation modules is 0, as shown in the following table.
Remote control protocol trigger framework
After the terminal device receives the data item sent by the master station, the processing process is similar to the above.
In the data items related to this embodiment, the remote adjustment command and the remote control command issued by the master station need to be responded by the terminal device in time, so that the trigger information corresponding to the remote adjustment command and the remote control command is set to 1. When a remote control command or a remote control command is received, other data items are executed in a suspending mode, and uplink resources are reserved.
And aiming at a specific data item, analyzing the occupation sequence of the corresponding running module to the resource, determining the running sequence, namely the priority, and further determining the configuration information of the running sequence.
For example, in the remote adjustment command, when the master station issues the power adjustment command, the purpose is to change the current power of the target device (slave device), and at this time, the master station side mainly cares whether the remote adjustment command is successfully issued, whether the slave device executes the power adjustment command, and whether the current power of the target device reaches the target value.
In order to realize quick response, the terminal equipment sets the remote regulation command as trigger information according to a remote regulation protocol trigger frame, other data items of the uplink command are suspended, and uplink channel resources are reserved; in the downlink operation module, firstly, remote regulation execution related to the power regulation command is executed, namely, the terminal equipment issues a remote regulation execution command to the slave equipment, and the slave equipment executes the power regulation command; and then, performing telemetering acquisition related to the result of the power regulation command, namely, the terminal equipment issues a telemetering acquisition command to the slave equipment, the slave equipment replies the current power value, and the terminal equipment bursts the power value fed back by the slave equipment to the master station. And the master station end judges according to the feedback value, the target value is reached, the remote regulation command is completed, the target value is not reached, and the regulation is continued.
In the remote regulation command, if the terminal equipment does not trigger the frame according to the remote regulation protocol, the command is randomly issued, and the slave equipment may execute the command irrelevant to the regulation power first, so that on one hand, an RS485 channel is occupied, and in addition, the master station cannot judge whether the remote regulation command succeeds or not according to the data, and the feedback speed of the execution result of the remote regulation command is influenced.
In the operation module corresponding to the remote regulation command, the remote measurement acquisition is carried out after the remote regulation execution and accords with the execution sequence, therefore, the configuration information of the remote regulation execution is set to be 2, the configuration information of the remote measurement acquisition is set to be 1, namely, according to the configuration information, the remote regulation execution is firstly carried out, the remote measurement acquisition is then carried out, and other operation modules do not directly contact the regulation power command and do not need to execute or be put into the following execution.
The protocol trigger framework can be modified according to actual requirements, and is suitable for different functional requirements.
And the terminal equipment and the slave equipment are in Modbus communication protocol. In the protocol, one register corresponds to one data.
In a conventional operation mode, when the terminal device obtains data of the slave device, the terminal device is instructed to upload all data once, such as voltage, current, power and the like of three phases.
When the slave device uploads a plurality of data once, the slave device occupies the RS485 channel for a long time, and only when the channel is idle, the terminal device can send a command, which may cause downlink channel blocking.
In this embodiment, the terminal device reads only one data at a time, i.e. instructs the slave device to transmit only one specific data at a time.
In step 1.5 of this embodiment, the slave device only sends one data at a time, which reduces the time for the slave device to reply and occupy the RS485 channel, and the terminal device can issue the command in time.
Further, the terminal device may change the order of reading the slave device data, for example, after sending the remote adjustment execution, then send the telemetry acquisition, and then read the power data, that is, after the slave device executes the power adjustment, the feedback value after the adjustment is acquired back.
At the moment, the uplink channel is already yielded, and the obtained power data can be uploaded to the master station in a burst mode in time, so that timely response is realized.
The data of the slave equipment is collected by the terminal equipment in real time, and the sequence of collecting the data by the terminal equipment is adjusted according to application requirements.
Through the technical measures, when the protocol trigger occurs, the downlink channel resource can be yielded more quickly, the data item in the protocol trigger frame is executed, and the command issued by the master station is responded quickly.
After the feedback information is successfully sent, the protocol triggering frame is completed, the protocol triggering is closed, and the normal operation is recovered.
