Embodiment
Below in conjunction with accompanying drawing, describe the specific embodiments of the remote upgrade method of a kind of GPRS terminal of the present invention in detail:
Based on the hardware circuit shown in Fig. 1, the remote upgrade method of GPRS terminal of the present invention, its concrete steps comprise:
1) preliminary treatment of upgrade code: after the upgrade code file that the upgrade server 2 being responsible for performing upgrading is sent at the application server 1 receiving responsible updating and management, first cyclic redundancy check (CRC) code (Cyclic Redundancy Check) verification and CRC check are carried out to whole upgrade code file, the check value of whole upgrade code and overall check code is added in upgrade code end of file, then, the upgrade code file adding this overall check code is divided into several code segments according to every frame 1KB usually, and the CRC check code of this section is added at the end of each code segment, and the code segment split is numbered in order,
2) upgrade notification:
Application server 1 issues upgrade command to all online GPRS terminals such as GPRS terminal 11, GPRS terminal 12, GPRS terminal 13, includes in upgrade command: No. ID and file size of the IP address of upgrade server 2 and port numbers, upgrade code file;
3) starting and upgrading:
Any online GPRS terminal, describes concrete code upgrade process for GPRS terminal 11 below:
GPRS terminal 11 connects according to the IP address of the upgrade server 2 in upgrade command and port numbers and upgrade server 2, and informs application server 1;
4) upgrading performs:
After GPRS terminal 11 and upgrade server 2 connect, send request order to upgrade server 2, include in request command: No. ID of upgrade code file and code segment numbering, upgrade server 2 is according to No. ID of the upgrade code file in request command and code segment numbering, the code segment of the reference numeral in this upgrade code file of No. ID is sent to GPRS terminal 11, after GPRS terminal 11 receives this code segment, first verify, if verification is passed through, the code segment of next numbering is then asked to upgrade server 2, if verification is not passed through, and unsanctioned number of times is not when reaching set point (this set point is between 3 ~ 5 usually), GPRS terminal 11 continues the code segment of this numbering of request, otherwise, interrupt this to download, disconnect the connection with upgrade server 2, and error situation is reported application server 1,
When numbered code segment is all downloaded complete, GPRS terminal 11 can verify whole upgrade code file, as verification is passed through, has then upgraded, and GPRS terminal 11 performs the upgrade code file after downloading after resetting and restarting; As verification is not passed through, then continue to perform original code file, if when the number of times of repeated downloads does not reach set point (this set point is between 1 ~ 3 usually), again from the beginning download upgrade code file;
GPRS terminal at least when downloading unsuccessful, reports upgrade case to application server 1, and whether download success rate for the ease of statistics and improve escalation policy, under normal circumstances, no matter download successfully, GPRS terminal all can report upgrade case to application server 1;
When occurring that the number of times interrupting downloading or download exceedes set point, first adjust escalation policy by application server 1: the length L reducing single frames, makes communication success rate Q between 0.58 ~ 0.62;
Wherein, S is signal strength signal intensity, and unit is dBm, L is single frames length, and unit is KB, T is temperature, and unit is degree, and V is voltage, and unit is volt; P1, P2, P3 and P4 are weighted value, difference 0.4,0.4,0.1 and 0.1, and its summation is 1;
When the length that have adjusted single frames still occurs that the number of times interrupting downloading or download exceedes set point, adjustment signal strength signal intensity is (away from base station 5 or the words that in unit area, mobile device is too much, significantly can reduce signal strength signal intensity), make communication success rate Q between 0.68 ~ 0.72, again download; When the length and signal strength signal intensity that have adjusted single frames still occur that the number of times interrupting downloading or download exceedes set point, transmission period can be adjusted, obtain suitable ambient temperature (such as in summer, evening, temperature was closer to the optimum working temperature of equipment, and winter, noon, temperature was closer to optimum working temperature), make communication success rate Q between 0.74 ~ 0.76, again download; When have adjusted the length of single frames, signal strength signal intensity and ambient temperature and still occurring that the number of times interrupting downloading or download exceedes set point, (supply power voltage is between 3.3V to 4.5V for the voltage of adjustment GPRS terminal, voltage is more close to 3.8V, the receiving sensitivity of GPRS terminal is higher), make communication success rate Q between 0.78 ~ 0.82, again download.
In actual application, in order to alleviate the workload of application server 1, the management of message queue remote measurement transmission (Message Queuing TelemetryTransport) shared usually by application server 1 by MQTT server 3, namely application server 1 is by communicating between MQTT server 3 with GPRS terminal.
When the number of times that download or repeated downloads still appear interrupting in the length that have adjusted single frames exceedes set point, communication success rate can also be improved by the length continuing adjustment single frames, maximum three times of the number of times of adjustment single frames length, communication success rate Q after three adjustment single frames length is respectively between 0.68 ~ 0.72,0.74 ~ 0.76,0.78 ~ 0.82, often adjust a single frames length, once download, if download successfully, then end of upgrading.
GPRS terminal is handled as follows the upgrade code after downloading, and whole code area is divided into four regions by GPRS terminal usually: BOOT district and boot section, APP1 district i.e. the first application area, APP2 district i.e. the second application area and ExtROM district and system parameters district;
BOOT district is used for depositing start-up code, when system startup optimization, first runs this section of code;
APP1 district and APP2 district are used alternatingly, if that is: current code file leaves APP1 district in, then the upgrade code file downloaded just leaves APP2 district in, and vice versa.
ExtROM district is used for storage system start-up parameter, and in order to indicate the code attribute in APP1 district and APP2 district, code attribute comprises: current can operation code, more fresh code, old code, free area; When GPRS terminal starts, first bring into operation from BOOT district, after BOOT completes firstization, the system start-up parameter in reading ExtROM district, enters and is marked as current can the code in operation code district and APP1 district or APP2 district bringing into operation.
In sum, be only preferred embodiment of the present invention, not be used for limiting scope of the invention process, all equalizations done according to shape, structure, feature and the spirit described in the claims in the present invention scope change and modify, and all should be included in right of the present invention.
