What described wireless communication module adopted is the GPRS/CDMA communication module.
The utility model is when concrete the use, telemetering terminal carries out data communication by the GPRS/CDMA mode, telemetering terminal carries out exchanges data by data network and administrative center and comprises active reporting, inquiry response etc., when equipment need to carry out code upgrade, telemetering terminal can carry out by network the remote upgrade of code.
the normal condition lower module is completed data interaction with communication server by the GPRS/CDMA mode, the telemetering terminal switchback is changed the code of program operation to the remote upgrade pattern when needs carry out the system code upgrading, telemetering terminal is connected to the code upgrade server automatically under this pattern, send the code upgrade request, the code upgrade server downloads to local FLASH to fresh code according to the agreement flow process after receiving upgrade request, by hypervisor, thereby user program is switched the upgrade job of backhauling row mode completing user code after code upgrade is completed and lower the cost that system software upgrading is safeguarded.
Under normal operation, telemetering terminal operates in the operation code pattern, and the timing of carrying out data by network reports, and fault reports immediately, the telemetry command inquiry response.In case there is the code upgrade request to be issued to telemetering terminal by network, the telemetering terminal hypervisor will according to the agreement process flow operation until completion code receives, be upgraded.
If system's operation is operation code, when code upgrade need to be done by system, the center sends the code upgrade order, telemetering terminal is placed loading remote upgrade code sign at command buffer after receiving the upgrading order, restart system, system can be automatically according to the sign upgrade code of reloading, beginning run time version upgrading flow process.
If system's operation is the remote upgrade program, system can the Lookup protocol parameter be connected to the code upgrade server, send the code upgrade request, upgrade server receives upgrade request can send to the distal terminus machine to fresh code more, arrange after verification is errorless and load the operation code sign, restart system, the operation code that system can automatically reload and upgrade according to sign, completion code remote upgrade.
