Adopt said system that the method for electric elevatable table inner parameter is set, comprise the steps:
The first step, connects host computer and electric elevatable table internal controller by hardware interface unit;
Second step, host computer and controller set up signal interface channel by carrying out shake communication;
3rd step, amendment parameter is transformed the backward controller of encryption and sends amendment signal by host computer; Controller receives described amendment signal, judges parameter change type, complete parameter change after deciphering.
Further describe below by specific embodiment:
1. on PC computer, open data configuration process software, comprise interface display module, parameter input module, parameter calculating module, parameter encrypting module, parameter sending module.
2., after File Open, connection is set
When connection is set, PORT COM can be selected in PC interface, select baud rate, if after foregoing coupling, PC sends the signal of a string Handshake Protocol, and protocol contents comprises identity of the sender, recipient's identity, communication handshake.If host computer is after transmission handshake, also receive self-controller and reply same signal, the match is successful to prove signal, connects between host computer and controller.
3. input amendment parameter on PC, is converted into usb signal by the signal of amendment parameter, and is sent outward by USB port, be encrypted operation simultaneously to signal, ensures the tightness that signal transmits.
Concrete, carry out as follows: by parameter input module, host computer gets type and the numerical value of amendment parameter; By parameter calculating module, the parameter type got is converted into the hexadecimal code that controller can identify by host computer, by the numerical value of parameter, is calculated as the data that controller can identify; By parameter encrypting module, by etc. parameter to be sent be encrypted; By parameter sending module, parameter modification signal is sent to controller.
Adopt the method for random value additional calculation encryption afterwards, when processing signals, the temporal information of random intercepting host computer, comprise minute numerical value, numerical value, and was placed on one and connected and to alter in signal on specific byte order second, simultaneously by after minute numerical value and numerical value addition in second, be put in another byte in signal, send with parameter information simultaneously, thus realize addition encryption function.
4. by the patchcord of USB RS 232, the usb signal that PC sends is converted into RS232 signal, thus strengthens the outside transfer capability of signal and anti-tampering ability, and lengthen the transmitting range of signal, prevent distorted signals or loss;
Turn SCI signaling module by RS232 signal, RS232 signal is converted into the SCI signal that controller single-chip microcomputer can identify, conveniently carry out reception and the process of single-chip microcomputer;
