2.2 preview video;
- Preview the video and pay attention to the server time of the current preview video operation, so as to find the log record of the corresponding operation in the found log file;
2.3 lookup log;
- Gateway log: [GPSGatewaySvr----libmdvrnet]];
2.4 analysis log;
- Find the corresponding operation log record in the downloaded gateway log file according to the operation time or protocol instruction;
- Refer to JTT 1078- 2016 on- board video communication protocol for satellite positioning system of road transport vehicles;
-
The video request instruction is [7E 91 01]];
-
At the same time, log analysis tools (applicable scope: 808/1078 protocol) can be used to analyze logs;
- A. Copy the complete log; As shown in the above figure:
- 7E 91 01 40 15 01 00 00 00 00 11 01 01 01 11 01 00 13 0D 31 39 32 2E 31 36 38 2E 31 2E 31 37 33 19 E7 00 00 02 00 01 08 7E
-
B. paste the log into the input box of the log analysis tool;
-
C. click "analysis" to know the information content contained in this instruction;
2.5 problem judgment;
-
A. No 9101 has been issued;
(1) The equipment protocol is incorrect, not the 1078 protocol (check the protocol type in the online status in the operation management);
(2) There is a problem with the server (look for technology); -
B. Is the server ip distributed in the 9101 correct (WEB server management, one- click configuration of server IP, check whether the obtained is consistent with the current database configuration);
-
C. If the result returned by the device is not 0, it may be that the protocol does not match and the device is not the 1078 protocol;
-
D. Reconfirm that the lower port is not accessible (6630 - - 6636 TCP);
