Description

Technical Field

[0001] This application relates to the field of electronic information system design, and particularly to a method for transmitting data increment in an electronic information system. Background Art

[0002] An electronic information system includes multiple subsystem modules and a network. Each subsystem module is connected to several unit modules. When designing the system, according to the interaction requirements of each unit module, the scheduling rules and network transmission protocols of each subsystem module and the network are determined. After the system has been running for some time, when new functions need to be added, the implementation of new function data will involve an increase in the data transmission path or the transmission of new data. The original scheduling rules of each subsystem module cannot parse and schedule the data involved in the new functions, so it is necessary to change the scheduling rules related to each subsystem module, that is, the scheduling rules of all subsystems involved in the transmission path through which the new function data passes need to be modified. Such modifications involve a large amount of work and long time consumption, and may affect the system stability. Summary of the Invention

[0003] In view of this, this application provides a method for transmitting data increment in an electronic information system, which solves the problems in the prior art. When the functions of the system increase, only the unit modules involved need to be changed, and the transmission of new function data can be completed without changing the scheduling rules of the subsystem modules, improving the scalability of the system.

The transmission method includes:

[0006] When the transmission path of the original data in the electronic information system increases or a new data transmission path needs to be added for new data transmission, the data corresponding to the added transmission path is used as new function data;

[0007] The unit module that forms the new function data is used as the data source unit module, and the subsystem module that finally analyzes and processes the new function data is used as the target subsystem module.

[0008] Design service functions residing on the computers of each subsystem module. When the data source unit module sends new function data to the target subsystem module, the data source unit module first sends the new function data to the subsystem module where it is located through the bus. The service function on the subsystem module where the data source unit module is located controls the reception of the new function data and sends the new function data to the target subsystem module. The target subsystem module parses the new function data to obtain the instruction data of the control unit module, and then sends the instruction data to the unit module serving as the execution unit.

[0009] Optionally, the new function data is sent from the data source unit module to the target subsystem module along a preset transmission path, which includes the subsystem module where the data source unit module is located, the target subsystem module, and one or more intermediate subsystem modules between the subsystem module where the data source unit module is located and the target subsystem module;

[0010] The service function on the subsystem module where the data source unit module is located and the service function of the intermediate subsystem module packetize the received data according to preset rules to form a transmission packet, and periodically send the transmission packet to the target subsystem module.

[0011] Optionally, the service function presets the format of the transmission packet. The format of the transmission packet includes an information field and several data packets. The data packets are used to fill in the information words of the new function data, and the information field is used to fill in the bus information of the transmission path.

[0012] Optionally, the format of the transmission packet further includes a flag word, which is used to fill in the function type of the new function data.

[0013] Optionally, the preset rules for packetization include:

[0014] The service function on the subsystem module where the data source unit module is located groups several new function data that need to be sent to the same intermediate subsystem module and the same target subsystem module into a transmission packet. When a transmission packet is saturated or the packetization period ends, the transmission packet is sent to the intermediate subsystem module, and the packetization of the next transmission packet is carried out. The information field of the transmission packet fills in the bus information of the transmission path;

[0015] The service function on the intermediate subsystem module reads the information field of the received transmission packet and sends it to the service function of the corresponding subsystem module according to the transmission path of the transmission packet;

[0016] After receiving the transmission packet, the target subsystem module parses the transmission packet and processes the new function data in the transmission packet to obtain the required instruction data.

[0017] Optionally, the data packet presets multiple digit formats, and according to the number of digits of the received data, data with different numbers of digits is placed into data packets with corresponding digit formats.

[0018] Optionally, a transmission packet includes data packets of multiple digit formats, and the number of data packets of each digit format is one or more.

[0019] Optionally, the data increment transmission method is used for an aircraft flight control system.

[0021] When the system of the present application is designed, service functions for transmitting new function data are designed on each subsystem module. The service functions are independent of other parts within the subsystem module, and the operation of the service functions does not affect the operation of other functions of the subsystem module. After the system design is completed, when there is no new function data generated, the data of each module is transmitted according to the original design of the system; if there is new function data, the service functions receive and send the new function data. The part other than the service function on the intermediate subsystem module does not process the new function data, and the service function only transfers and transmits the new function data. Only the unit modules involved in the new function data need to be changed, so that the system does not need to be redesigned, saving costs and ensuring system stability. Description of the Drawings

[0029] The embodiment of the present application provides a transmission method for data increment in an electronic information system.

[0030] As Figure 1 shown, multiple subsystem modules of the electronic information system are connected and communicate through a bus. A plurality of unit modules are connected to the subsystem module through the bus. The unit module communicates with the subsystem module through the bus. The subsystem module receives the data sent by each connected unit module, and the subsystem module sends the data received from other subsystem modules to the unit module connected to itself. Among them, the unit module is a sensor or an action execution unit.

[0031] A method for transmitting data increment in an electronic information system according to the present application includes:

[0032] When the transmission path of the original data in the electronic information system increases or a new data transmission path needs to be added for new data transmission, the data corresponding to the added transmission path is used as new function data;

[0033] Design service functions resident on the computers of the subsystem modules on each subsystem module. The service functions are used to process the new function data on the bus between the subsystem module and the unit module where they are located, and the service functions are used to process the new function data on the bus between each subsystem module. The unit module that forms the new function data is used as the data source unit module, and the subsystem module that finally analyzes and processes the new function data is used as the target subsystem module.

[0034] When the functions of the system increase, change the operating programs on the data source unit module, the subsystem module where the data source unit module is located, and the target subsystem module. Specifically, change the operating programs of the data source unit module and the subsystem module where the data source unit module is located to generate new function data, and change the operating program of the target subsystem module to parse and utilize the new function data. Other subsystem modules and unit modules remain unchanged. In one embodiment, when the new function data is original data, change the operating program of the subsystem module where the data source unit module is located to mark a new transmission path for the data.

[0035] During the process of the data source unit module sending the new function data to the target subsystem module, the data source unit module first sends the new function data to the subsystem module where it is located through the bus. After the subsystem module where the data source unit module is located marks the transmission path for the new function data, the service function on the subsystem module where the data source unit module is located controls the reception of the new function data and sends the new function data to the target subsystem module. The target subsystem module parses the new function data to obtain the instruction data of the control unit module, and then sends the instruction data to the unit module of the execution unit.

[0036] According to the network protocol and scheduling rules initially designed for the system, when the data on the unit module needs to be sent to another subsystem module through a certain bus and perform action control on the unit module to which it belongs, the data of the unit module is sent to the data module of the subsystem module where it is located, and the data module of the subsystem module parses and processes the data, and then sends the processed data to the target subsystem through the bus. The target subsystem module then parses and processes the data to obtain a control instruction and sends it to the unit module serving as the execution unit. When there is a need for new functions, the program codes of the subsystem module where the data source unit module is located and the target subsystem module are adjusted. This adjustment is necessary for the generation and utilization of new function data. When the new function data is transmitted from a unit module under one subsystem module to a unit module under another subsystem module, it needs to pass through multiple subsystem modules. However, for the other multiple subsystem modules except the subsystem module where the data source unit module is located and the target subsystem module, since the other subsystem modules do not utilize the new function data and only act as a transmission role, and often the bus network under each subsystem module and the bus network between systems are different. The intermediate subsystem module needs to change the subsystem module scheduling rules and operating programs to complete the reception and transmission of new function data. In this way, when there is new function data, the scheduling rules of all the subsystem modules through which the new function data passes need to be changed. This method results in a huge workload, equivalent to redesigning the system. The cost of designing the scheduling rules of each subsystem module for transmitting new function data is relatively high, and it may affect the system operation stability.

[0037] In the system design of this application, service functions for the transmission of new function data are designed on each subsystem module. The service functions are independent of other parts within the subsystem module, and the operation of the service functions does not affect the operation of other functions of the subsystem module. After the system design is completed, when there is no new function data generated, the data of each module is transmitted according to the original design of the system as described above. If there is new function data, the operating programs on the data source unit module, the subsystem module where the data source unit module is located, and the target subsystem module are changed. For the multiple intermediate subsystem modules, the service functions are used to control the reception and transmission of new function data. The parts of the intermediate subsystem modules other than the service functions do not process the new function data. The service functions only transfer and transmit the new function data, so that it is not necessary to redesign all the subsystem modules, saving costs and ensuring the stable operation of the system.

[0038] The new feature data is sent from the data source unit module to the target subsystem module according to the transmission path of the preset bus. The transmission path includes the subsystem module where the data source unit module is located, the target subsystem module, and one or more intermediate subsystem modules between the subsystem module where the data source unit module is located and the target subsystem module. The service function on the subsystem module where the data source unit module is located and the service function of the intermediate subsystem module packetize the received data according to the preset rules to form a transmission packet, and periodically send the transmission packet to the target subsystem module.

[0039] The service function presets the format of the transmission packet. The format of the transmission packet includes an information field and several data packets. The data packets are used to fill in the information words of the new feature data, and the information field is used to fill in the bus information of the transmission path.

[0040] In one embodiment, the preset rules for packetization include:

[0041] According to the transmission path of the new feature data, the service function on the subsystem module where the data source unit module is located groups several new feature data that need to be sent to the same intermediate subsystem module and the same target subsystem module into a transmission packet. When a transmission packet is saturated or the packetization period ends, the transmission packet is sent to the intermediate subsystem module, and the packetization of the next transmission packet is performed. The information field of the transmission packet fills in the bus information of the subsequent transmission path in the transmission packet.

[0042] The service function on the intermediate subsystem module reads the information field of the received transmission packet and sends it to the service function of the corresponding subsystem module according to the transmission path of the transmission packet, until the transmission packet is sent to the target subsystem module after passing through all the intermediate subsystem modules in the transmission path.

[0043] After receiving the transmission packet, the target subsystem module parses the transmission packet and processes the new feature data in the transmission packet to obtain the required instruction data.

[0044] Among them, the service function on the subsystem module where the data source unit module is located can preset multiple transmission packets and preset the paths of the information fields of various transmission packets. The corresponding transmission packet receives the new feature data of the corresponding transmission path. When the transmission path of the new feature data is not available in the preset information field of the transmission packet, a transmission packet can be added manually, and the path information of its information field can be set.

[0045] The service function continuously receives new feature data within a cycle, packetizes the received data within the cycle, and when the cycle ends, regardless of whether the transmission packet is saturated, the packetization is completed and sent out.

[0046] Regarding the preset packetization rules, in another embodiment, the preset rules for packetization include:

[0047] According to the transmission path of the new function data, the service function on the subsystem module where the data source unit module is located groups the new function data that needs to be sent to the same intermediate subsystem module into one transmission packet, and groups the new function data that needs to be sent to different intermediate subsystem modules into different transmission packets. When a transmission packet is saturated or the packet assembly cycle ends, the transmission packet is sent to the intermediate subsystem module, and the packet assembly of the next transmission packet is carried out. Among them, the information field of the transmission packet fills in the bus information of the subsequent transmission path of the new function data.

[0048] The intermediate subsystem module groups the new function data that needs to be sent to the same target subsystem module into one transmission packet, and groups the new function data that needs to be sent to different target subsystem modules into different transmission packets. When a transmission packet is saturated or the packet assembly cycle ends, the transmission packet is sent to the corresponding target subsystem module, and the packet assembly of the next transmission packet is carried out. Among them, the information field of the transmission packet formed by the service function of the intermediate subsystem module is the bus information of the subsequent transmission path of the new function data.

[0049] After receiving the transmission packet, the target subsystem module parses the transmission packet and processes the new function data in the transmission packet to obtain the required instruction data.

[0050] Regarding the preset packet assembly rules, in another embodiment, the preset packet assembly rules include:

[0051] The format of the transmission packet further includes a flag word, and the flag word is used to fill in the function type of the new function data, and the function type is such as maintenance data, fault data, etc.

[0052] According to the transmission path of the new function data, when the service function on the subsystem module where the data source unit module is located assembles packets, several new function data of the same function type and that need to be sent to the same intermediate subsystem module and the same target subsystem module are grouped into one transmission packet. When a transmission packet is saturated or the packet assembly cycle ends, the transmission packet is sent to the intermediate subsystem module, and the packet assembly of the next transmission packet is carried out. The information field of the transmission packet fills in the bus information of the subsequent transmission path of the new function data;

[0053] The service function on the intermediate subsystem module will read the information field of the received transmission packet and send it to the corresponding target subsystem module according to the transmission path of the transmission packet until the transmission packet is sent to the target subsystem module after passing through all the intermediate subsystem modules in the transmission path;

[0054] After receiving the transmission packet, the target subsystem module parses the transmission packet and processes the new function data in the transmission packet to obtain the required instruction data.

[0055] When transmitting new function data, classify the function types of the data to facilitate the centralized processing of the new function data received by the target subsystem module and improve the data processing efficiency.

[0056] The data packet is preset with multiple bit formats. According to the number of bits of the received data, the data with different numbers of bits is placed into the data packets with corresponding bit formats. A transmission packet includes data packets with multiple bit formats, and the number of data packets with each bit format is one or more. According to the different received data formats, the different formats are selectively placed into appropriate data packets to improve the utilization rate of the data packets.

[0057] Specifically, for the new function data with multiple bit formats, there are data packets with different bit formats in a transmission packet. For example, there are a 8-bit data packets, b 16-bit data packets, and c 32-bit data packets. During the packet assembly process, an 8-bit new function data can be placed into an 8-bit data packet, or two 8-bit new function data can be placed into a 16-bit data packet, or four 8-bit new function data can be placed into a 32-bit data packet; two 8-bit new function data and a 16-bit new function data can also be placed into a 32-bit data, and so on. Preset the values of a, b, and c according to actual needs, and place the new function data with the received bit format into the data packet with available spaces.

[0058] The data increment transmission method of this application can be used in the flight control system of an aircraft.

[0059] The above is only the specific implementation manner of this application, but the protection scope of this application is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by this application should be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
