First embodiment
Fig. 1 and Fig. 2 are please referred to, the embodiment of the invention provides a kind of on-Line Monitor Device 100, the on-Line Monitor Devices
100 include temperature sensor 130, humidity sensor 120, the first connecting line 140, the second connecting line 150, the first shielded cable
240, secondary shielding cable 250 and processor 110, humidity sensor 120 pass through the first connecting line 140 and 110 electricity of processor
Connection, temperature sensor 130 are electrically connected by the second connecting line 150 with processor 110, and humidity sensor 120 is for obtaining one
The humidity information of body to be detected, temperature sensor 130 are used to obtain the temperature information of body to be detected, and processor 110 is for passing through
Temperature information judges whether body to be detected breaks down with humidity information.
Specifically, in embodiment, temperature sensor 130 uses thermo-sensitive resistor, and resistance value can be with environment temperature
Change and changes；Humidity sensor 120 uses humicap, and capacitance can change with the variation of ambient humidity, together
When, it includes weld on the high steam pipeline 300 that body to be detected described in the present embodiment, which is high steam pipeline 300, will be warm
Degree sensor 130 and humidity sensor 120 are installed on the ambient gas that can be realized detection weld close to the position of weld
Humidity information and temperature information effect.Due to when high-temperature steam leakage occurs, temperature information around weld with it is wet
Degree information can change, therefore by the temperature information and humidity information of detection weld, and temperature information and humidity information are passed
It transports to processor 110 to be handled and analyzed, can determine whether weld occurs high-temperature steam leakage accident, reach detection
The effect whether weld breaks down.
In addition, measuring probe uses PT1000 temperature sensor and capacitance type humidity sensor resistant to high temperature, it is ensured that its
Steady in a long-term works in the high irradiation zone of nuclear power station, and is resistant to hot and humid environment.Of course, in some other implementations
In example, body to be detected may be other devices, can be realized judgement by way of detection temperature information and/or humidity information
The device whether to break down can be used as body to be detected, and the present embodiment does not do any restriction to this.
Furthermore, it is desirable to explanation, the present embodiment is used the form of seperated cable, that is, passes through the first connecting line 140, the
Two connecting lines 150 are electrically connected with humidity sensor 120 with temperature sensor 130 and processor 110 respectively, can be directly online by this
Monitoring device 100 is installed on jet chimney 300, so that the response time of measurement is faster, precision is higher, and stability is more preferable, structure
Simpler, overall cost is lower.
Specifically, in the present embodiment, it is connect by the first core wire 141 with the second core wire 142 with the both ends of humicap,
And processor 110 is enable to acquire the wet of current environment by the first core wire 141 and the second core wire 142 and humicap in turn
Spend information.However, in practical applications, can have parasitic capacitance between the first core wire 141 and the second core wire 142, and also
Electromagnetic interference signal can be generated, for the accuracy of data acquisition, needs to eliminate the electromagnetic interference signal.In view of this, this reality
The on-Line Monitor Device 100 for applying example offer includes the first shielded cable 240, secondary shielding cable 250, wherein the first shielding line
Cable 240 is sheathed on outside the first core wire 141, and secondary shielding cable 250 is sheathed on the first connecting line 140, the second connecting line 150 and
Outside one shielded cable 240, and secondary shielding cable 250 is grounded.The first core wire can be eliminated by the first shielded cable 240
141 and the second electromagnetic interference between core wire 142, the interference signal outside eliminating can be realized by secondary shielding cable 250,
So that the humidity information and temperature information of detection are more accurate.
Further, the parasitic capacitance between the first core wire 141 and the second core wire 142, the capacitance is in the first core wire 141
It is certain value after being determined with the length of the second core wire 142.Meanwhile the processing for the ease of processor 110 for signal, online
Detection device further includes oscillating circuit module 170, wherein oscillating circuit module 170 passes through the first core wire 141 and the second core wire
142 are electrically connected with humicap, and oscillating circuit is also electrically connected with processor 110.Wherein, oscillating circuit module 170 is for producing
Square-wave signal after raw humicap and parasitic capacitance superposition, in order to which processor 110 carries out signal processing, due to parasitic electricity
Holding is definite value, therefore the frequency of square-wave signal can change with the variation of humicap, and the frequency variation of square-wave signal is only
Variation with humicap has relationship.
Meanwhile after the first shielded cable 240 is set, between the first shielded cable 240 and the first core wire 141 there is also etc.
Parasitic capacitance is imitated, and, it is generally the case that the equivalent parasitic capacitances are tens times of humicap, are generated to humicap
Electric signal is affected, result even in signal can not identify, therefore in the present embodiment, on-Line Monitor Device 100 further includes
Equipotential circuit module 160, equipotential circuit module 160 are connect with the first core wire 141, the first shielded cable 240 respectively, so that
Equipotential state is between first core wire 141 and the first shielded cable 240, to eliminate the equivalent parasitic capacitances to humicap
The influence of the electric signal of generation.
Also, in the prior art, thermo-sensitive resistor and processor 110 are attached by two core wires, but in reality

Wherein, four-wire system temperature measurement circuit module 180 is used to generate the voltage signal Vrx of thermo-sensitive resistor, due to thermo-sensitive resistor
There are dead resistances Rc1, Rc2 on the signal cable at both ends, so that the voltage signal that Rx is generated generates deviation delta Vrx, so that real
The voltage signal Vrx ' that border measures=Vrx+ Δ Vrx.In order to eliminate the influence of Δ Vrx, using four-wire system temperature measurement circuit module
180, the both threads cable of same dead resistance parameter is linked into thermo-sensitive resistor both ends, utilizes four-wire system temperature measurement circuit module 180
Internal processing of circuit forms electric bridge in the inside of four-wire system temperature measurement circuit module 180, and equal proportion eliminates the shadow on four core wires
It rings, i.e. Δ Vrx=0, and then the thermo-sensitive resistor voltage signal for obtaining measuring circuit is Vrx, final measurement result is more smart
Really.
Due to using the equipotential cable parasitic capacitance technology for eliminating and four-wire system temperature measurement technology of above-mentioned innovation,
Exchanging cable does not influence measurement accuracy, only needs disassembly temperature sensor, humidity sensor and corresponding meter body in this way,
Under conditions of dismantling cable, periodic maintenance and calibration are carried out to instrumentation.Concrete operations are as follows: the temperature that will be disassembled
