5. engineering machinery remote control method according to claim 4 is characterized in that, in steps A and the step e, described Long-distance Control authorization command comprises: order initial symbol, authorization command sign, licencing key, authorization command, order end mark; Described authorization command comprises: allow Long-distance Control, close Long-distance Control, revise licencing key.
6. engineering machinery remote control method according to claim 1, it is characterized in that, among the step C, described remote control command comprises: order initial symbol, control command sign, Long-distance Control password, control command, order end mark, described control command comprises revises the Long-distance Control password.
7. engineering machinery remote control method according to claim 1, it is characterized in that, Long-distance Control password described in licencing key described in steps A and the step e and the step C, respectively by Long-distance Control authorized administrator and remote control management person's keeping, password allows to revise again, and default licencing key and Long-distance Control password storage are in the static data memory module.
8. engineering machinery remote control method according to claim 1 is characterized in that, described Long-distance Control licensing status sign comprises that Long-distance Control allows to close two states with Long-distance Control; Revise Long-distance Control licensing status sign by licencing key, under the situation that obtains the Long-distance Control mandate, just carry out Long-distance Control with the Long-distance Control password.
9. engineering machinery remote control method according to claim 1 is characterized in that, described step D, and implementation step is:
D1: resolve the remote monitoring order,, directly withdraw from,, change D2 if resolve successfully if the command format mistake is disregarded;
D2: judge Long-distance Control licensing status sign,, reply " Long-distance Control unauthorized ", withdraw from if Long-distance Control is closed; If Long-distance Control allows, change D3;
D3: read the Long-distance Control password in the static data memory module, and compare,, reply " Long-distance Control password mistake ", withdraw from, if the password coupling is changeed D4 if do not match with the Long-distance Control password that receives;
D4: the requirement according to control command is carried out;
D5: be finished, reply " Long-distance Control success ".
10. engineering machinery remote control method according to claim 1, it is characterized in that, in the above-mentioned substep of step D, message answer mode is identical with the message mode of step C, if step C adopts short message, then be returned to mobile communication equipment,, then reply packet to monitoring server in the mobile communication data business mode equally if step C employing is the mobile communication data business mode with short message way;
If once need to carry out multinomial Long-distance Control, repeating step C and step D send different remote control commands and realize, and need not repetitive endowment, still, if through step e and step F, need to carry out new remote control command after mandate is closed, then need repeating step A-F again.
