Embodiment 8
The as described above Emergency radiological monitoring and notification system for being suitable to the simplification of high temperature nuclear reactor off site emergency, the present embodiment with
Its difference is:
The security of HTGR is very high, but we still need the running status of HTGR is exercised supervision,
The emergency response of HTGR general possible without core meltdown therefore corresponding Emergency radiological monitoring Yu notification system
Time can suitably lengthen, but appropriate lengthening is only its reality for existing Emergency radiological monitoring and notification system
On be still to need to be responded in a short period of time.In actual treatment, due to processing server and policy server
Apart from far, therefore use wireless connection, in this case, once occur near HTGR local nuclear radiation increase or
Leakage, if now the wireless signal in the region signal intensity occurs not enough or connects not smooth problem, processes very may be used not in time
Loss difficult to the appraisal can be brought to normal meeting an urgent need.
To solve the problem, as shown in Fig. 2 the Emergency radiological monitoring suitable for HTGR is with notification system also

So, the policy server 3 can enable active service when processing server 2 cannot carry out proper communication
Device 6 is communicated, and does not interfere with the decision-making of policy server 3 so, and decision-making order normal issue, also avoid nothing
Line communicates the unstable loss brought to contingency operation, such that it is able to quick emergent, treatment in time.
The computing formula of the communication quality is:
Wherein, MiDetermined by following formula:
xi=xi2-xi1
Wherein, xi1It is i-th delivery time of heartbeat packet, xi2For i-th heartbeat packet correspondence returns to the time of reception wrapped, xi
It is i-th intercycle of heartbeat packet, D is normal interval, MiIt is i-th judgement factor of heartbeat packet, n is to send heartbeat packet
Sum, P is communication quality.
Wherein, D is constant, is set according to actual conditions.
Basic ideas are:First calculate the intercycle of heartbeat packet, then the ratio according to normal interval and intercycle to
Under round the judgement factor for obtaining heartbeat packet;It is all to judge that the ratio between factor sum and heartbeat packet sum are required communication quality.
Have the beneficial effect that:Setting normal interval, the intercycle of heartbeat packet can be determined by adjusting normal interval is
No is admissible, is admissible, between intercycle is more than or equal to normally if intercycle is less than normal interval
Every not allowing then;The judgement factor is converted to by rounding downwards, then if admissible, its decision content is more than 0
Positive integer;If do not allow, its decision content is 0, and intercycle is smaller, judges that the factor is also bigger;By to judge because
Son summation, is required communication quality by and with heartbeat packet ratio of number, can eliminate the judgement factor pair in allowed band
The influence of communication quality;And communication quality is bigger, represent that the communication speed between two working nodes is faster;So, by this
Formula can directly obtain the communication quality of policy server 3 and processing server 2, and formula is simple, and convenience of calculation is quick, saves
System resource.
