The advantage that this long-range control method based on script has is as follows:
(1) without carrying out complicated string matching, control end is no matter send the control instruction of what form and control the grammer that parameter only need to meet script to controlled terminal, finally can carry out by the script resolver resolves of controlled terminal, write extra string matching code without developer.
(2) size of code is optimized, use script and script resolver, only need to realize at controlled terminal code and the hardware api interface of script resolver, write separately analysis program without the control instruction of each the outer relay part to controlled terminal, reduce greatly size of code.
(3) amendment is convenient, different with traditional mode, if newly-increased or Optimized code, what revise is the script language code that controlled terminal sends, instead of the script analytic language environment of controlled terminal, so without the ROM on programming controlled terminal again, amendment is convenient.
(4) control flexibly, owing to can transmit the code snippet of script arbitrarily in control message, therefore can Use a code, in code, contain abundant parameter, or use the code combination of multiple statements to realize complicated merit Can; No matter in control message, comprise a statement, or multiple statements, say for controlled terminal, be all that use is same Script resolver is carried out, and the code of controlled terminal, without any amendment, is controlled flexibility ratio considerably beyond traditional control The mode of character string.
