Summary of the invention
The object of this invention is to provide a kind of temperature variation alarm line of coaxial configuration, above-mentioned like product defect can be overcome, will not limit by use length, environment temperature and length of being heated completely, and reusable.
A kind of temperature variation alarm line of coaxial configuration, microcomputer modulator is connected with temperature variation alarm line and terminal resistance, it is characterized in that temperature variation alarm line structure: three or four conductor coaxial settings, clad is by the outer coated NTC elastomeric material layer successively of axle center first conductor, coated second conductor, coated 2nd NTC elastomeric material layer, coated 3rd conductor, external sheath layer, in temperature variation alarm line, the first conductor and the second conductor connect and compose the first loop and establish first terminal resistance, second conductor and the 3rd conductor connect and compose second servo loop and establish the second terminal resistance, the absolute value of the electrical quantity change value difference in two loop a certain moment of microcomputer modulator Real-time Collection temperature variation alarm line, when the heating rate of temperature variation alarm line environment temperature is less than 10 DEG C/min, when the absolute value of the electrical quantity change value difference in two loops is less than presetting alarming threshold value, be normal monitoring state, when environment temperature heating rate meets or exceeds 10 DEG C/min, when the absolute value of the electrical quantity change value difference in microcomputer modulator collection two loops is more than or equal to predetermined alarming threshold value, microcomputer modulation exports differential temperature alerting signal, and goes out constant temperature alerting signal when also can be more than or equal to predetermined alarming threshold value according to the electrical parameter values change in two loops.
The temperature variation alarm line of a kind of coaxial configuration of the present invention compared with prior art tool has the following advantages:
1, the restriction of length and environment temperature is not used completely by temperature variation alarm line.
2, differential temperature report to the police with temperature variation alarm line be heated length have nothing to do.
3, only consider the absolute value of the electrical quantity change value difference in two loop a certain moment, when whether being more than or equal to presetting alarming threshold value, be that microcomputer modulation exports differential temperature alerting signal, no, microcomputer modulation is in normal monitoring duty.
Differential temperature can be realized report to the police by simply calculating, thus reduce produce because of complicated deterministic process wrong report, fail to report, further increase again accuracy and the reliability of warning.
Temperature variation alarm line of the present invention can arrange differential temperature warning heating rate: response in 10 DEG C/min(20s ~ 140s), response in 20 DEG C/min(22.5s ~ 90s), response in 30 DEG C/min(15s ~ 60s), be suitable for wider temperature range, be particularly useful for fire temperature rise ratio place faster.Product quality reliability is high, and cost is low, and temperature-sensitive warning sensitivity is high, can meet the performance requirement of GB16280-2005 " line-type heat detector " and supplementary provision.This temperature variation alarm line is reusable.
