Abstract
The invention provides a software loading method using a 1553B bus. The entire loading method includes the following steps: formulating a 1553B bus communication protocol between a control computer and a software loading device; adding a 1553B bus software loading functional module to the bottom layer software PUBIT of the control computer; powering on the control computer and completing the self-check; if handshake information from the software loading device is received within specified time, sending feedback information to the software loading device and completing the software loading according to the subsequently received destination file and loading address; after the completion of loading, sending feedback information to the software loading device. Under the premise of not dismounting the covering cap of the guided missile, the software loading is realized by using the 1553B bus through connecting the software loading device with the guided missile separation plug. Compared with the RS232 serial port loading method, the 1553B bus loading method is easier to operate and higher in speed and reliability.
Description
Technical field
The present invention relates to a kind of Kind of Missile Control Computer method for loading software, particularly a kind of by 1553B bus software loading method.
Background technology
Computer for controlling is the core component of missile flight control system, and the object code that Flight Control Software compiling generates needs to be loaded in computer for controlling.In the development process of model, due to the change of various demand, Flight Control Software needs constantly to change upgrading.In the past in Project R&D, all carry out Bootload by the RS232 serial ports of computer for controlling test port, carry out Bootload upgrading after shooting and need bomb disposal upper flap, then pull down the blanking cover of computer for controlling test port and connect RS232 serial ports loaded cable, carry out Bootload upgrading again, need to pull down the loaded cable of test port after software upgrading and blanking cover connected again, make guided missile return to software upgrading before state.Whole process need expends larger manpower and time, and risk and the fifth wheel that may there is accidental damage product in the process of dismounting fall into the problem bringing repeated disassembled and assembled cabin section in the section of cabin simultaneously.
Prior art can not meet the needs of people, and for making up prior art deficiency, the present invention aims to provide a kind of 1553B bus software loading method.
For achieving the above object, the present invention by the following technical solutions: a kind of 1553B bus software loading method, whole loading method comprises the following steps:
Step one: the 1553B bus protocol formulating computer for controlling and Bootload equipment room, comprises address information, handshaking information, data transmission format;
Step 2: increase 1553B bus software value-added tax function module in the PUBIT software of computer for controlling bottom software, realize computer for controlling to power on and after completing Autonomous test, if receive the handshaking information of Bootload equipment within the time of agreement, send feedback information to Bootload equipment, and complete Bootload according to subsequently received file destination and load address, load rear transmission feedback information to Bootload equipment;
Step 3: that passes through the 1553B bus cycles after Bootload device start sends handshaking information to computer for controlling, sends software object file, load address information after receiving the feedback information of computer for controlling.
Compared with prior art, the invention has the beneficial effects as follows: it is under the prerequisite of not bomb disposal upper flap, to be connected with guided missile breakaway plug by Bootload equipment and to use 1553B bus to realize Bootload.Relative RS232 serial ports loading method, 1553B bus loading method is simple to operate more simply, speed is faster, reliability is higher.

Step 2: increase 1553B bus software value-added tax function module (software flow as shown in Figure 2) in the PUBIT software of computer for controlling bottom software, computer for controlling powers on and after completing Autonomous test, if receive the handshaking information that Bootload equipment sends, send feedback information to Bootload equipment, and complete Bootload according to subsequently received object code and load address, load rear transmission feedback information to Bootload equipment;
Step 3: Bootload equipment is connected with guided missile breakaway plug, realize the power supply of guided missile, RT address is arranged and 1553B bus communication, that passes through the 1553B bus cycles after Bootload device start sends handshaking information to computer for controlling, after receiving the feedback information of computer for controlling, software object codes, load address information is sent to computer for controlling.
The present invention has been successfully applied to certain model air-to-surface missile, achieves expected effect, can use, have a extensive future in other model projects.
To those skilled in the art, obviously the invention is not restricted to the details of above-mentioned one exemplary embodiment, and when not deviating from spirit of the present invention or essential characteristic, the present invention can be realized in other specific forms.Therefore, no matter from which point, all should embodiment be regarded as exemplary, and be nonrestrictive, scope of the present invention is limited by claims instead of above-mentioned explanation, and all changes be therefore intended in the implication of the equivalency by dropping on claim and scope are included in the present invention.Any Reference numeral in claim should be considered as the claim involved by limiting.
The above; be only preferred embodiment of the present invention; not in order to limit the present invention, every above embodiment is done according to technical spirit of the present invention any trickle amendment, equivalently replace and improve, within the protection domain that all should be included in technical solution of the present invention.
