Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
See also Fig. 1, as shown in fig. 1, the temperature monitoring of aerogenerator and warning system comprise temperature sensor 1, signal converter 2, and described signal converter 2 comprises two input interfaces 21, measuring unit 22, signal processing unit 23, converting unit 24 and the output interface 25 that connects successively; Described temperature sensor 22 is arranged in the cabin of aerogenerator and with an input interface 21 of signal converter 2, is connected, by temperature sensor with the measuring unit 22 of the temperature real-time Transmission in cabin to signal converter 2; After the temperature signal measurement that 22 pairs of temperature sensors 1 of measuring unit by signal converter 2 transport amplifies, secondly process through 23 pairs of signals of signal processing unit, be converted to the constant current signal linear with dut temperature finally by crossing converting unit 24, send the server 4 of ground master-control room by output interface 25 to; Another input interface 21 is connected with the starting switch 3 of the extinguishing device of aerogenerator, and the starting switch by extinguishing device is transferred to signal converter 2 with the switching value of extinguishing device enabling signal and present position signal; Temperature monitoring signal and the enable position signal of extinguishing device and the server 4 that alerting signal is transferred to the ground master-control room that the output interface 25 of signal converter 2 will be changed by cable.
The output interface 25 of described signal converter 2 is RS485 interface or TCP/IP interface.
Described temperature sensor 1 is electronic temperature sensor, can be at an easy rate by selecting suitable thermistor to change temperature regulating range and working temperature, and to responsive to temperature and be swift in response.
The temperature monitoring of the utility model aerogenerator and warning system are carried out Real-Time Monitoring by temperature sensor and signal converter to the temperature of aerogenerator, and the temperature signal that will monitor, fire alarm signal and extinguishing device enable position signal by cable transmission to the ground master-control room; And reliability is high, and the non-maintaining cycle reaches 10 years.
Further, as shown in Figure 2, described signal converter 2 also is provided with temperature compensator 26, and described temperature compensator 26 is connected in measuring unit 22; , by signal than the actual temperature high error of temperature compensator 26 auto-compensations because of signal converter output, avoid bringing wrong judgement to the operations staff.Temperature compensator 26 is to produce a direct current signal millivolt generator that changes with the variation of actual temperature, when temperature compensator 26 is connected on measuring unit 22 thermometric, actual temperature is compensated, the signal of erasure signal converter output and the error between actual temperature, be consistent both.
Further, as shown in Figure 2, described signal converter 2 also is provided with power-off protecting circuit 27, and described power-off protecting circuit 27 is connected in measuring unit 22; To cause the accident because the galvanic couple silk fracture of wire of temperature sensor 1 lost efficacy temperature control when preventing that measuring unit 22 from carrying out temperature survey; the power-off protecting circuit 27 that arranges is when thermopair fracture of wire or loose contact; make the maximal value of the signal transducer output value of establishing scope;, so that the server of master-control room is cut off the electricity supply, check and change action.
Above disclosed is only preferred embodiment of the present utility model, certainly can not limit with this interest field of the utility model, and the equivalent variations of therefore according to the utility model claim, doing, still belong to the scope that the utility model is contained.
