Embodiment
Below in conjunction with the drawings and specific embodiments the intelligent bus molded lines sensing fire detector that has a type thermal sensing element that the utility model provides is elaborated.The parts identical with prior art adopt identical drawing reference numeral, to omitting its explanation of carrying out.
As shown in Figure 2, the intelligent bus molded lines sensing fire detector that has a type thermal sensing element that the utility model provides comprises boxcar 7, many data/power buss 8, a plurality of intelligently encoding temperature measurement module 20 and many linear temperature sensors 11; Wherein boxcar 7 is electrically connected with an end of many data/power buss 8; A plurality of spacing distances are that 1～200 meter intelligently encoding temperature measurement module 20 parallel connections are distributed on many data/power buss 8; Be connected with one on each intelligently encoding temperature measurement module 20 between two adjacent intelligently encoding temperature measurement modules 20, with the length linear temperature sensor 11 about equally of the 8 parallel settings of data/power bus and length and data/power bus 8, and temperature measuring circuit is housed; Linear temperature sensor 11 for continuous distribution NTC parallel connection type, continuous distribution PTC connection type, continuous distribution NTC parallel-connected thermo couple type, intermittently distribute thermal sensing element type in parallel, the interrupted series thermal-sensitive element type that distributes; Also be connected with a some type thermal sensing element or some type temperature element 30 on described each intelligently encoding temperature measurement module 20.Data/power bus 8 is used for transmitting address and warning message between boxcar 7 and intelligently encoding temperature measurement module 20, and to 20 power supplies of intelligently encoding temperature measurement module.The fire information that is connected in parallel on the some type thermal sensing element on each intelligently encoding temperature measurement module 20 on data/power bus 8 or some type temperature element 30 and each bar linear temperature sensor 11 is is periodically patrolled and examined in boxcar 7 timesharing, and, send fire alarm signal immediately in case receive some type thermal sensing element or some type temperature element 30 or linear temperature sensor 11 detected fire alarm situations on the intelligently encoding temperature measurement module 20.
Described some type thermal sensing element 30 is thermoswitch, temperature detect switch (TDS), temperature switch, thermal protector, as bimetallic strip type switch, CTR type switch, mercury type switch, PTC type switch etc.
Described some type temperature element 30 is thermocouple type, thermosensitive resistance type, bimetal type, PN junction type, integrated circuit type, optical-fiber type etc.
Described some type thermal sensing element or some type temperature element 30 also can formation be intertwined with linear temperature sensor (NTC parallel connection type, PTC tandem type, NTC/PTC thermocouple type etc.).
In addition, because data/power bus 8 is four-core, five cores or six cored structures, when with itself and linear temperature sensor 11 parallel settings, its with linear temperature sensor 11 on can also a shared lead between two detecting conductors, thereby can make the quantity minimizing of core.
In addition, in order to improve the warning sensitivity of a type thermal sensing element or some type temperature element 30, it can be arranged on outside the housing of intelligently encoding temperature measurement module 20.
As mentioned above, an end of linear temperature sensor 11 is electrically connected with the measuring junction of intelligently encoding temperature measurement module 20, and its other end can connect one and be used for the terminal resistance that loop fault detects.This terminal resistance can be installed in the adjacent intelligently encoding temperature measurement module 20, also can draw by other circuit to be back in above-mentioned and the intelligently encoding temperature measurement module 20 that linear temperature sensor 11 1 ends link to each other, but also can be provided with separately.
The alarm temperature that linear temperature sensor 11 is set must satisfy: 1. do not report to the police under the highest permission environment temperature of the fire detector of national Specification (alarm temperature of setting as fire detector is 85 ℃, and its high ambient temperature is 60 ℃); 2. the minimum permission alarm temperature (alarm temperature as fire detector is 85 ℃, and its minimum permission alarm temperature is 77 ℃) that is not less than the specified alarm temperature of fire detector can be reported to the police.Be failure to actuate when the highest permission environment temperature in order to satisfy fire detector, the setting alarm temperature in linear temperature sensor 11 loops is generally than higher.The setting alarm temperature of described some type thermal sensing element or some type temperature element 30 must satisfy: the highest permission environment temperature of fire detector (alarm temperature as fire detector is 85 ℃, and its highest permission environment temperature is 60 ℃) that does not 1. exceed national Specification; 2. do not exceed the maximum operating temperature that intelligently encoding temperature measurement module 20 allows; 3. be not less than the minimum permission alarm temperature (alarm temperature as fire detector is 85 ℃, and its minimum permission alarm temperature is 77 ℃) of the specified alarm temperature of fire detector; 4. be not less than detector is carried out the high temperature exposure heating-up temperature in when test.Like this, if the alarm temperature that this point type thermal sensing element or point type temperature element 30 are set is certain certain value (as 78 ℃), intelligently encoding temperature measurement module 20 carries out temperature detection to linear temperature sensor 11 loops and some type thermal sensing element or some type temperature element 30 loops simultaneously, when in a single day the heating temperature of intelligently encoding temperature measurement module 20 is elevated to the setting alarm temperature (as 78 ℃) in a type thermal sensing element or some type temperature element 30 loops, whether the heating temperature no matter linear temperature sensor 11 loops are detected reaches the alarm temperature (alarm temperature as setting is 90 ℃) of its setting, fire detector sends fire alarm signal immediately, can avoid Yin Wendu further to raise like this and influences the operate as normal of intelligently encoding temperature measurement module 20.When intelligently encoding temperature measurement module 20 residing heating temperatures do not reach the setting alarm temperature (as 78 ℃) in a type thermal sensing element or some type temperature element 30 loops, be that intelligently encoding temperature measurement module 20 is in the highest permission operating ambient temperature of electronic chip on it or device, and the heating temperature that linear temperature sensor 11 loops are detected is when having reached the alarm temperature (is 90 ℃ as the alarm temperature set) of its setting, fire detector also can send fire alarm signal, in the time of so just can overcoming residing heating-up temperature of intelligently encoding temperature measurement module in the intelligent bus parallel connection thermal sensitive element type linetype temperature-sensing fire detector of prior art or environment temperature and in a single day exceed the maximum operating temperature that its electronic chip or device allow, the problem of fire detector cisco unity malfunction.
