【The content of the invention】
Present invention aim at solve to need artificial wiring brush machine during traditional single-chip microcomputer brush machine, when needing to write with a brush dipped in Chinese ink firmware
When single-chip microcomputer reaches certain amount, the inefficiency by way of firmware is write with a brush dipped in Chinese ink in artificial wiring, and waste time and energy；When single-chip microcomputer is put
When in Package casing, write with a brush dipped in Chinese ink firmware and often also need to take shell apart, be inconvenient profit；When the excessive single-chip microcomputer of firmware content can not
During disposable storage, the not enough of the problem write with a brush dipped in Chinese ink one by one is needed and a kind of new network multiple single chip microcomputer that provide once is brushed
Machine system and implementation method.
The present invention is achieved through the following technical solutions：A kind of network multiple single chip microcomputer once brush machine system and
Implementation method, comprises the steps：
(1) prepare to build the hardware system of network multiple single chip microcomputer once brush machine system；Hardware system by need brush
All single-chip microcomputers of firmware and a PC end are constituted；
(2) all single-chip microcomputers and PC ends connect network simultaneously；
(3) PC ends are identified by different IP address to single-chip microcomputer；
(4) by self-defining communication protocol, PC ends send firmware content to all single-chip microcomputers and write with a brush dipped in Chinese ink one by one firmware to
All single-chip microcomputers；
(5) by self-defining Verification for Communication Protocols firmware content；
(6) complete to send firmware content.
Further, hardware system is made up of all single-chip microcomputers for needing brush firmware and a PC end in the step (1),
All single-chip microcomputers turn WIFI module comprising external serial ports or raspberry group supports that the system module of WIFI, PC ends must be supported to send
Firmware and interface display.
Further, all single-chip microcomputers of the step (2) and PC ends connect network simultaneously；By router transmitting WIFI letters
Number, and all single-chip microcomputers and PC ends connect upper this WIFI signal simultaneously.
Further, step (3) the PC ends are identified by different IP address to single-chip microcomputer；In connection network letter
On the premise of number, with PC ends single-chip microcomputer is connected one by one, and the IP address to single-chip microcomputer is modified, and is such as revised as
192.168.1.1,192.168.1.2,192.168.1.3,192.168.1.4,192.168.1.n.
Further, the step (4) by self-defining communication protocol, PC ends send firmware content to all single-chip microcomputers
And firmware is write with a brush dipped in Chinese ink one by one to all single-chip microcomputers；Self-defining communication protocol is：0xbe+1byte id+1byte sequence+
2bytes length+N bytes data, when sending lower a piece of news every time, sequence number adds one, and during re-transmission, sequence number is constant.
Further, the step (5) is by self-defining Verification for Communication Protocols firmware content；PC ends send every time one
After message, the response for receiving the identical sequence number that single-chip microcomputer sends is needed just to carry out the transmission of next serial number message,
Automatically the message is resend after otherwise 1s, sequence number is constant, re-transmission does not receive yet afterwards response 5 times and is then judged to time-out；
If repeatedly receiving the message of same sequence number, the message for only receiving for the first time is effective, on the basis of original, when main frame sends
After Send_Over, slave computer is needed to No. 02 message of one same sequence number of host computer response；Afterwards slave computer is under transmission
One sequence number sends checking message to host computer；
Empirical tests, if transmission information can not be mutually matched with response message, the message failure returns to step
(4), continue to send firmware content；
Empirical tests, if transmission information can be mutually matched with response message, the message correctly sends, and goes to step
(6), it is successfully transmitted firmware content.
Further, the step (6) completes to send firmware content, the interface display brush machine success of PC ends.
The beneficial effects of the present invention is：
(1) it is in hgher efficiency, in conventional brush write method, ability brush machine after wiring, and a single-chip microcomputer can only be write with a brush dipped in Chinese ink every time
Firmware, introduce network brush machine method after, the firmware that can simultaneously support multi-disc single-chip microcomputer updates, greatly improve renewal consolidate
The efficiency of part, greatly reduces workload；
(2) write with a brush dipped in Chinese ink firmware to be more convenient, when needing the single-chip microcomputer for writing with a brush dipped in Chinese ink firmware to reach certain amount, by artificial wiring brush
The mode for writing firmware is very inconvenient, and wastes time and energy, and when single-chip microcomputer is placed in Package casing, writes with a brush dipped in Chinese ink firmware and often also needs to
Take shell apart, be inconvenient profit, firmware is write with a brush dipped in Chinese ink by way of network convenient；
(3) function is write with a brush dipped in Chinese ink more diversified, after introducing self-defining communication protocol so that during single-chip microcomputer renewal firmware not
Whole firmwares must be disposably stored, solves the problems, such as that firmware content is excessive well, make to write with a brush dipped in Chinese ink firmware functional diversities.
