Information.Either server can be by accessing data monitor center or data collecting module collected arrives for third-party mobile phone
Carbonomonoxide concentration information and temperature information.It can also be data monitor center, by above-mentioned carbonomonoxide concentration information and temperature
Degree information is uploaded to third party's mobile phone or server.
It is understood that due to construction environment, the difference of cost, the collection one specifically set in a pickup area aoxidizes
The quantity of the steel pipe of carbon and the number of the temperature-sensing element set are probably different.In same piping lane, each piping lane
The length of subregion is probably that the number of different, adjacent point one pickup areas of middle setting is also likely to be different.In some realities
Apply in example, because fire separation setting is nearer, therefore can also be set at the fire separation being spaced after one or more fire separation
Put vasculum, i.e. pickup area corresponding to vasculum and can be across one or more fire separation between the position of vasculum
's.
The technical scheme of the information of above-mentioned interval setting case collection piping lane subregion solves power supply, the biography that sensor is related to
The problems such as defeated distance, transmission stability, suitable for being applied in extensive, long range pipe gallery.
In certain embodiments, the temperature sensor is K-type armoured thermocouple.Armoured thermocouple passes as temperature survey
Sensor, it has many advantages, such as bending, be high pressure resistant, thermal response time is fast and sturdy and durable, and it and industrial assembled are warm
Galvanic couple is the same, the sensor as measurement temperature.
In one embodiment, by temperature and carbonomonoxide concentration comprehensive descision whether reach open fire resistant doorsets when
Machine：
(1) maximum temperature is reduced to below threshold temperature (see Fig. 6) in pipe gallery；And
(2) highest carbonomonoxide concentration is less than the 20% of LEL (volume fraction) in pipe gallery；
When in the carbonomonoxide concentration data received, highest carbonomonoxide concentration is higher than LEL (volume fraction)
When 20%, by opened smoke-discharging blower fan, carbon monoxide in pipe gallery is excluded, until highest carbonomonoxide concentration is reduced to blast
Less than the 20% of lower limit (volume fraction), now think resume combustion can not possibly occur in piping lane.
(after i.e. carbonomonoxide concentration is less than the 20% of LEL), opened after judging can not possibly to occur in piping lane resume combustion
Fire resistant doorsets and smoke evacuation system, exclude the waste gas of incident area.
It is understood that flame range temperature collect module and carbonomonoxide concentration detecting module can be also used in piping lane
Real-time fire alarm, i.e., when any one of carbonomonoxide concentration or temperature are higher than preset value, trigger data center produces police
