If being not received by the communication link before communication link establishes timer expiry establishes response message, judge
The radio detection terminal is not received by communication link and establishes response message, is simultaneously stopped and resets the communication link and establishes
Timer；
If receiving the communication link before communication link establishes timer expiry establishes response message, described in judgement
Radio detection terminal receives communication link and establishes response message, is simultaneously stopped and resets the communication link and establishes timer.
8. utilizing the water pollution detection system of radio detection terminal as claimed in claim 7, it is characterised in that: wherein, described
Water pollution status report reception confirmation message is sent by following steps:
After the monitoring center is successfully received the water pollution state report, it is dirty that the water is parsed by the monitoring center
Dye state report is accorded with obtaining the unique identity corresponding to the radio detection terminal；
Generate water pollution status report reception confirmation message, wherein include in the water pollution status report reception confirmation message
The received unique identity corresponding to the radio detection terminal accord with；
The water pollution status report reception confirmation message is broadcasted by the monitoring center.
9. utilizing the water pollution detection system of radio detection terminal as claimed in claim 8, it is characterised in that: wherein, judgement
Whether the radio detection terminal, which receives water pollution status report reception confirmation message, is carried out by following steps:
After the radio detection terminal sends water pollution state report to the monitoring center with the first power, described in starting
Water pollution status report transmissions timer in radio detection terminal；
If it is true to be not received by the water pollution status report reception before water pollution status report transmissions timer expiry
Recognize message, then judges that the radio detection terminal is not received by water pollution status report reception confirmation message, be simultaneously stopped simultaneously
Reset the water pollution status report transmissions timer；
If receiving the water pollution status report reception confirmation before water pollution status report transmissions timer expiry to disappear
Breath, then judge the unique body corresponding to the radio detection terminal for including in the water pollution status report reception confirmation message
Whether part identifier is consistent with the transmitted unique identity symbol corresponding to the radio detection terminal；
If the unique body corresponding to the radio detection terminal for including in the water pollution status report reception confirmation message
Part identifier and the transmitted unique identity symbol corresponding to the radio detection terminal are consistent, then judge the wireless inspection
It is fixed to survey terminal and receive water pollution status report reception confirmation message, be simultaneously stopped and reset the water pollution status report transmissions
When device.
10. utilizing the water pollution detection system of radio detection terminal as claimed in claim 6, it is characterised in that: wherein, different
Radio detection terminal there is different Random Waiting Times, and wherein, second power is higher than first power.
