Abstract
The present invention is for remote terminal data dispatch mechanism in 1553B bus, propose a kind of 1553B bus universe message trigger control method, by extending 2 vector font query messages, vector font sequence is identified using certain 1 BIT of vector font, remaining BIT identifies whether corresponding subaddressing has new data, it solves the problems, such as the control of RT subaddressing universe message trigger, meets application demand to greatest extent, ensure that the time delay certainty and its application range of onboard networks.
Description
Technical field
The present invention relates to a kind of transmission data managing methods for being used for 1553B bus communication remote terminal (RT) message.
Background technique
1553B is command/response type multiplex data bus, and RT can only be executed according to the order of bus control unit (BC)
Corresponding data transmit-receive operation.When RT has new data to update, BC knows and organizes to send to order in time, to data transmission
Real-time is most important, with the increase of 1553B bus load, at present using the message for sending vector font 16 subaddressings of control
Triggering mode has been unable to meet application demand, is badly in need of realizing the control of universe message trigger, expands application range.
Summary of the invention
The present invention proposes a kind of 1553B bus universe message trigger control method, simply and effectively realizes universe message
Triggering control.
Technical scheme is as follows:
The 1553B bus universe message trigger control method, BC continuously transmit multiple vector font query messages, in vector font
For certain BIT for identifying vector font sequence, remaining BIT identifies whether corresponding RT subaddressing has new data；When some RT has new data
When sending, 1 is set on the correspondence position of vector font, and organizes to send to order in time by BC to send destination for RT new data.
BC can be specifically set to continuously transmit two vector font query messages, the BIT15 of first vector font is set as 0,
BIT0-BIT14 corresponding with RT subaddressing 1-15, and the BIT15 of second vector font is set as 1, BIT0-BIT14 and RT
Address 16-30 is corresponding, to guarantee that the new data of RT subaddressing 1-30 timely and effectively transmits.
The invention has the following advantages that
The control of universe message trigger is simply and effectively realized, there is scalability, expands application range.
Detailed description of the invention
Fig. 1 is 1553B bus topolopy figure；
Fig. 2 is the end the present invention program BC process flow.
Fig. 3 is the present invention program RT new data refresh flow figure.
Specific embodiment
1553B is command/response type multiplex data bus, and topological structure is as shown in Figure 1, BC is responsible for whole network
Communication and management, subsystem access 1553B network by RT, the communication in realization and network between other systems.
Whether the present invention inquires it by sending vector word command (mode code 10000) to the same RT twice in succession
There is new data, and by the timely organizing transmission order of BC.Vector font sequence, remaining BIT mark are identified using certain 1 BIT of vector font
Know whether corresponding subaddressing has new data.It is sent for example, the BIT15 of the 1st vector font is set as 0, BIT0-BIT14 with RT
Subaddressing 1-15 is corresponding, the BIT15 of the 2nd vector font be set as 1, BIT0-BIT14 it is corresponding with RT transmission subaddressing 16-30,
It when some subaddressing has new data to send, is corresponded in its vector font and sets 1 on position, and organize to send order in time for RT by BC
New data is sent to destination, ensure that the new data of RT subaddressing 1-30 timely and effectively transmits, and realizes the touching of universe message
Hair control.
Specific implementation process is as shown in Figure 2 and Figure 3:
When some subaddressing of RT has new data to send, subsystem is write new data into pair by call driver
The subaddressing data space answered, and by the service request position 1 of the corresponding vector font of the subaddressing.
BC sends according to RT period of the bus indicator to all normal responses in network and " sends vector font 1, send vector
Word 2 " is ordered, and whether the vector font for detecting RT loopback has service request bit to be set to 1, asks if so, BC will set the service immediately
It asks the transmission order of the corresponding RT subaddressing in position to be set to effectively, the data of the RT subaddressing is allowed to be sent to destination in time；If
There is no service request bit to be set to 1, BC to continue to inquire next RT.
After RT is connected to " send vector font 1 " order of BC transmission, 1 content of vector font is sent to BC, while by vector font 2
Content be assigned to protocol chip vector font transmission unit.
After RT is connected to " send vector font 2 " order of BC transmission, 2 content of vector font is sent to BC, while by vector font 1
Content be assigned to protocol chip vector font transmission unit.
After BC organizes RT new data to send, RT is removed and is corresponded to position in vector font 1 or vector font 2, and by 1 assignment of vector font
For protocol chip register.
Claims (1)
1. a kind of 1553B bus universe message trigger control method, it is characterised in that:
BC continuously transmits two vector font query messages to the same RT, certain BIT sets 1,0 respectively in two vector fonts, for marking
Know vector font sequence, remaining BIT identifies whether corresponding RT subaddressing has new data；Specific set-up mode are as follows: first vector font
BIT15 be set as 0, BIT0-BIT14 it is corresponding with RT subaddressing 1-15, the BIT15 of second vector font is set as 1,
BIT0-BIT14 corresponding with RT subaddressing 16-30；
When some RT has new data to send, 1 is set on the correspondence position for the vector font for being passed back to BC, and hair-weaving is organized by BC in time
It loses one's life to enable and sends destination for RT new data.
