Temperature exceeding standard situation, for example, when temperature exceeding standard temperature nodes be 10 when light flash time interval be less than temperature exceeding standard
Temperature nodes be 5 situation.In the present embodiment, alarm 500 is arranged in control room, but not limited to this.
In addition, if it is determined that in temperature nodes temperature 400A~F, some is exceeded, then being sent to corresponding temperature nodes
Interval adjustment signal, interval adjustment signal is used to shorten the time interval that corresponding temperature nodes gather measured parameter value.It is then warm
Spend node and receive interval adjustment signal and the corresponding time interval for shortening collecting temperature measured value.If it is determined that there is measured parameter value
Beyond the situation that default value is interval, then illustrate that temperature fluctuation occur in the temperature nodes, now shorten the collection of measured parameter value
Time interval, can preferably be counted with understanding this temperature fluctuation, and then precisely judge that the temperature fluctuation occurred is abnormal disturbs
Dynamic point still reflects overall temperature conditions, improves the precision of early warning.
If not sending temperature exceeding standard signal within the early warning cycle, the current early warning cycle is exited.As described above, according to
The early warning cycle is compared judgement and sends temperature exceeding standard signal, considers the overall temperature in cold (warm) storehouse in a period of time
Degree situation, rejects local abnormal noise spot, improves the precision of alarm.
For example for freezer, preset temperature range includes upper and lower bound, is set if opening refrigeration when temperature exceedes the upper limit
It is standby that freezer refrigerating is cooled, stop refrigeration when measured parameter value is less than lower limit；Measured parameter value is possible to be more than the upper limit or small
In lower limit, because refrigerating device refrigeration is uneven, it is possible to cause the temperature of some temperature nodes temporarily exceeded, but now freezer
Bulk temperature to be sufficient for demand to cold, refrigeration plant also normal, if using traditional alert mode, will be right
False alarm occurs for one freezer normally run, and uses the time and again principle or average principle of the present invention, can filter these temporary
Temperature exceeding standard, the filtering false alarm of when property, improve the efficiency of management.
