These terms are only used to distinguish one element from another. For example, a first xx script may be referred to as a second xx script, and similarly, a second xx script may be referred to as a first xx script, without departing from the scope of the present application.
Fig. 1 is a diagram of an application environment of a message scheduling method provided in an embodiment, as shown in fig. 1, in the application environment, including a network controller 110 and a network terminal 120.
The network controller 110 may be an independent physical server or terminal, or may be a server cluster composed of a plurality of physical servers.
The network terminal 120 is a device capable of processing and uploading data collected by the sensor, and mainly receives a command sent by the network controller and passively sends data to the network controller 110.
The network controller 110 and the network terminals 120 may be connected through an optical fiber network, the network controller 110 may be an NC node in an FC-AE-1553 bus, and the network terminals may be NT nodes in the FC-AE-1553 bus, and generally, one network controller 110 is connected to and communicates with 20 network terminals 120, which is not limited herein.
For example, the network controller is a bus network control node on board, the network terminal may be a bus network terminal node located on a wing or a fuselage, and the network terminal node may upload various sensor data on board.
As shown in fig. 2, in an embodiment, a message scheduling method is proposed, and this embodiment is mainly illustrated by applying the method to the network controller 110 in fig. 1. The method specifically comprises the following steps:
step S202, a mask inquiry message is sent to a target network terminal, and the target network terminal is a network terminal of data to be uploaded;
step S204, receiving and analyzing a mask returned by the target network terminal, wherein the mask is used for identifying a sub-address of data needing to be read back in the target network terminal;
step S206, sending a message read-back instruction to a target network terminal, wherein the message read-back instruction is used for enabling the data in the sub-address of the data to be read back to be sent to a network controller through the target network terminal.
In one embodiment, the network terminal cannot actively send message data to the network controller, and usually the network controller sends a query command to the network terminal to query whether the network terminal uploads data; specifically, the network controller can send the command to the network terminal through the address information of the network terminal itself, and then send the command to the corresponding sub-address through the sub-address value of the sub-address carried under the network terminal. Among the network terminals, there are some network terminals for periodically sending data to the network controller, the network terminals are preset and known by the network controller, the network controller communicates with the network terminals one by one in a period to upload data, and the network terminal to be uploaded may be a target network terminal. Therefore, after the network controller sends the mask query message to the target network terminal, the target network terminal can receive the mask query message and send the mask to the network controller.
In one embodiment, one sub-address may be set among several sub-addresses of the network terminal to store the mask.
In one embodiment, a network terminal may carry several sub-addresses, such as 256, 128, etc., without specific limitation. Each subaddress may represent the subaddress by a subaddress value, and each subaddress may map a block of memory in hardware for storing specific data.
In one embodiment, a network controller receives and analyzes a mask, the mask is used for identifying states of sub-addresses under a target network terminal, some sub-address states exist and no data are uploaded to the network controller, some sub-address states exist and data are uploaded to the network controller, the mask can correspondingly identify the states of the sub-addresses, the sub-addresses with data uploaded are sub-addresses needing to read back data, and the network controller can know the sub-addresses needing to read back data under the current target network terminal after analyzing the mask. The network controller knows the sub-addresses where data needs to be read back, i.e. can communicate with these sub-addresses only in one cycle, without communicating with all sub-addresses.
In one embodiment, a network controller sends message read-back instructions to a target terminal, each message read-back instruction is only communicated with one sub-address under the target network terminal, the message read-back instruction can instruct the network terminal to upload data in the sub-address, and since the network controller knows which sub-addresses have data, the network controller can send the data read-back instruction only to the sub-address needing data read-back, and the data in the sub-address needing data read-back can be sent to the network controller through the target network terminal.
In this embodiment, the network controller obtains the data in the sub-address no longer in a polling manner for the sub-address of the network terminal, but obtains the data storage state of each sub-address by obtaining the mask, and then obtains the sub-address that needs to read back the data in the target network terminal, and then obtains the data only for the sub-address that needs to read back the data, so that the efficiency of data processing is greatly improved, and the real-time performance of data uploading in the network terminal can also be ensured.
In one embodiment, the mask word size is configured to correspond to the number of subaddresses of the target network terminal. In some large systems, a network terminal may be connected to more components, such as different sensors, or may need to upload more different types of data, so that a network terminal needs to set more sub-addresses and send different data to a network controller respectively; the mask itself can be corresponded to the sub-address by setting the word length; for example, if a bit corresponds to the state of a sub-address, if a certain sub-address needs to be read back, i.e. the bit at the position corresponding to the sub-address in the mask is "1", then by setting a sub-address separately to store the mask, the state of the sub-address storing the mask may not necessarily be identified. Therefore, the present embodiment can identify the state of the sub-address by using the mask in a large bus system, so as to facilitate the efficiency of uploading data from the network terminal to the network controller.
Referring to fig. 3, in an embodiment, step S206, the step of sending a message read-back instruction to the target network terminal includes:
step S302, a plurality of message read-back instructions are generated according to the mask;
step S304, writing the message read-back instruction into a message queue;
step S306, sequentially sending the message read-back commands in the message queue to the target network terminal.
In one embodiment, after the mask is analyzed, it may be determined which sub-addresses in the target network terminal have message data to be read back, and then a plurality of message read-back instructions are generated for the sub-addresses requiring the read-back message, where each message read-back instruction may excite one sub-address in the target network terminal to send the message data to the network controller, and after the network terminal receives the message read-back instruction, the corresponding sub-address may send the cached data to the network controller.
In one embodiment, the message read-back instructions are generated and then written into a message queue, i.e. arranged in sequence, so as to facilitate the ordered sending of the message read-back instructions and the sending of the message read-back instructions one by one. When different network terminals are target network terminals, the message read-back instructions for each target network terminal can be written into a message queue in a sequential arrangement mode and then executed.
In one embodiment, the message read-back commands in the message queue are sequentially sent, specifically to the target network side, to communicate with the corresponding sub-addresses in the target network terminal.
In one embodiment, the network controller stores preset configuration information, and the network controller may accurately send a mask query message to the target network terminal according to the configuration information, such as the current number of network terminals, address information of each network terminal, sub-address information of a mask stored in the network terminal, word length information of the mask, and a total network terminal lookup table, and then send a message read-back instruction to the target network terminal. Specifically, the network controller may query the address value of the corresponding target network terminal according to the network terminal query table, and specify the sub-address value in the target network terminal corresponding to the mask query instruction and the sub-address value in the target network terminal corresponding to the message read-back instruction; the network controller can send the mask inquiry message or the message read-back instruction to the bus in the form of a command frame, then the mask inquiry message or the message read-back instruction is received by the target network on the bus, and then the target network terminal executes the corresponding instruction to enable the corresponding sub-address to upload the corresponding data.
As shown in fig. 4, in an embodiment, the step after the step S304 writes the message read-back instruction into the message queue further includes:
step 402, sequentially sending mask inquiry messages to target network terminals;
step 404, if the masks of all the target network terminals are obtained, determining whether a preset protection time is reached;
in step 406, if the preset guard time is reached, the message queue is emptied.
In one embodiment, the network controller schedules the messages periodically, that is, the communication with the network terminals is periodic, and in one message scheduling period, the network controller sends mask query messages to all the network terminals in a polling manner, so that whether the mask query messages are sent to all the network terminals needs to be confirmed, and if not, the network terminals which do not receive the masks send the mask query messages, so that the current network terminals can conveniently send data to the network controller;
if all network terminals have sent the mask inquiry message and received the corresponding mask, then further confirming whether the protection time is reached, and if the protection time is reached, emptying the message queue. The protection time is a preset parameter, and the duration of the protection time is less than the duration of the message scheduling period. And emptying the message queue after the protection time length is reached, wherein the execution time length of the message read-back instruction is mainly limited, and the message queue is used for preventing the network terminal from overflowing due to excessive data uploaded according to the message read-back instruction, so that the message scheduling cycle is jittered and the accuracy of the message scheduling cycle is influenced.
In an embodiment, after the sub-address storing data in the network terminal uploads the data according to the message read-back instruction, a corresponding bit of the sub-address in the mask may be set to "0", which indicates that no data of the sub-address needs to be uploaded in the current message scheduling period. And when the protection time is up, the message queue is emptied, and if data in some sub-addresses in a certain target network terminal are not uploaded, the data can be uploaded in the next message scheduling period. And the message is prevented from being lost, the message scheduling period is ensured not to be jittered, and the reliability is improved.
In an embodiment, the message scheduling period is used to control the target network terminal data uploading period, a message scheduling period duration may be preset to 100ms, and a message protection time duration may be preset to 80 ms.
