Abstract
The invention discloses a FlexRay bus-based multimachine program online upgrade method. In the traditional industrial control field, the method of upgrading an application program of the equipment is realized in a manner of updating each unit separately. In the method disclosed by the invention, a hardware device only needs a USB-to-FlexRay debugger to connect MCUs (lower computers) with a PC (an upper computer) to realize multimachine program online upgrade; by adopting the method, application programs of multiple units (up to 124 units) can be upgraded simultaneously, the transmission rate of the FlexRay bus can reach 8 Mbps, the participation of professionals is not needed in the multimachine program online upgrade process, correct operation can be performed according to the simple PC interface, and thus the application upgrade efficiency of the industrial control system is improved.
Description
Technical field
What the present invention relates to is industrial control field, and refering in particular to is a kind of industrial control system multimachine program on-line upgrading method based on FlexRay bus.
Background technology
The method of in traditional industrial control field, equipment being carried out to application program updating mostly is to be upgraded individually to each unit.Therefore in program upgrade process, must carry out a large amount of identical operations to each unit, cause having reduced widely the upgrading efficiency of system.Although also there is in recent years the method for some multimachine program on-line upgradings, they are mostly based on designing compared with low speed and compared with old bus, and there is no the man-machine interface of easy operating.Therefore the method for these program on-line upgradings or because of a large amount of work repeating, or because of lower message transmission rate, again or there is no flat-footed operation interface and cause the reduction greatly of system upgrade efficiency ground.
Summary of the invention
The object of the invention is to, propose a kind of method of new industrial control system multimachine program on-line upgrading.Aim to provide a short and sweet easy-operating upper computer software, user-friendly; Aim to provide a kind of multimachine program upgrade device, reduce burden for users; Aim to provide a kind of high-speed procedure upgrade-system, improve system upgrade efficiency.
A kind of industrial control system multimachine program on-line upgrading method based on FlexRay bus depends on lower device: MCU unit (slave computer), USB turn FlexRay debugger, PC (host computer); Multiple MCU unit (slave computer) turns FlexRay debugger with PC (main frame) by USB and is connected;
Step 1: when system powers on after also initialization, all slave computers unit enters BOOTLOADER space, and waits for the order of shaking hands that host computer sends;
Step 2: the mode that host computer triggered by the time sends to slave computer the order of shaking hands, and wait for the answer signal that receives slave computer.Just proceed program updates work if receive at least one answer signal, if do not receive this time program updates of any answer signal constipation bundle.
Step 3: if slave computer unit has successfully received the order of shaking hands, send an answer signal to host computer.If slave computer unit do not receive shake hands order the direct redirect in slave computer unit enter application space;
Step 4: the mode that host computer triggered by the time sends the information of the subsequent Frame that will send sends corresponding Frame after distributing;
Step 5: the information of slave computer unit receiving data frames just receives corresponding Frame after receiving;
Step 6: the Frame that the verification of slave computer unit is received, if just errorless according to the Frame application programs space that receives upgrading accordingly, otherwise termination routine;
Step 7: host computer judges whether to send all data, if do not send repeating step four～step 7, finishes this program updates if sent.
The invention has the beneficial effects as follows: can carry out program on-line upgrading (maximum quantity can arrive 124 appendent computer systems) to multiple slave computers unit simultaneously, and articulate traffic rate under the slave computer unit of maximum quantity in bus and can reach 8Mbps, and just can correctly operate according to the host computer interface of being easily understood without professional's participation, improve the program upgrade efficiency of industrial control system.

Embodiment
In conjunction with Fig. 1, present embodiment is described, this embodiment turns FlexRay debugger by multiple MCU unit (slave computer) by USB and is connected with PC (host computer);
In conjunction with Fig. 2, present embodiment is described, this embodiment:
Step 1: when system powers on after also initialization, all slave computers unit enters BOOTLOADER space, and waits for the order of shaking hands that host computer sends;
Step 2: the mode that host computer triggered by the time sends to slave computer the order of shaking hands, and wait for the answer signal that receives slave computer.Just proceed program updates work if receive at least one answer signal, if do not receive this time program updates of any answer signal constipation bundle;
Step 3: if slave computer unit has successfully received the order of shaking hands, send an answer signal to host computer.If slave computer unit do not receive shake hands order the direct redirect in slave computer unit enter application space;
Step 4: the mode that host computer triggered by the time sends the information of the subsequent Frame that will send just sends corresponding Frame after distributing;
Step 5: the information of slave computer unit receiving data frames just receives corresponding Frame after receiving;
Step 6: the Frame that the verification of slave computer unit is received, if just errorless according to the Frame application programs space that receives upgrading accordingly, otherwise termination routine;
Step 7: host computer judges whether to send all data, if do not send repeating step four～step 7, finishes this program updates if sent.
