A length of 15 seconds, shutdown inquiry timer duration 10 seconds.
Step 2, vehicle-mounted station terminal initiate register flow path, obtain periodic handshake timer duration 15 seconds.
Step 3, Vehicle mounted station terminal periodic are shaken hands time-out, send handshake request to core net, core net replys handshake response
Message is to terminal.
The cycle shakes hands intervalometer again for step 4, successful terminal of shaking hands, and core net restarts crucial detection intervalometer.
By examples detailed above it is achieved that being periodically detected to the SOT state of termination.
In another example, terminal is shut down after normal work firmly.Originally it is that pass machine testing in example comprises the steps：
Step 1, operation and maintenance module setting shutdown quick detection timer duration 30 seconds, during periodic handshake intervalometer
A length of 15 seconds, shutdown inquiry timer duration 10 seconds.
Step 2, vehicle-mounted station terminal initiate register flow path, obtain periodic handshake timer duration 15 seconds.
Step 3, Vehicle mounted station terminal periodic are shaken hands time-out, send handshake request to core net, core net replys handshake response
Message is to terminal.
The cycle shakes hands intervalometer again for step 4, successful terminal of shaking hands, and core net restarts pass machine testing intervalometer.
Step 5, the unexpected power-off shutdown of vehicle-mounted station terminal.
Step 6, core net shutdown quick detection timer expiry, putting the SOT state of termination is false shutdown, and starts shutdown inquiry
Intervalometer, sends shutdown inquiry request message to target terminal.
Step 7, shutdown inquiry timer expiry, putting the SOT state of termination is shutdown, and is shown to operation and maintenance interface.
In aforesaid way, by the reasonable duration arranging each intervalometer, it is possible to achieve the quick inspection of terminal power-off state
Survey.
