Embodiment
The functional tester of a kind of wind-powered electricity generation unit vibration monitoring device that the utility model is provided below in conjunction with Fig. 1-Fig. 4 is elaborated.
As shown in Figure 1, the functional tester of described a kind of wind-powered electricity generation unit vibration monitoring device mainly comprises: signal output unit 100, and communication unit 110, storage unit 120, control module 130 is left unit 140 and status display unit 150, wherein:
High-speed memory 122 is used for metadata cache, and present embodiment adopts 512k multi-usage FLASH.
Leave unit 140 and be electrically connected, be used to realize the isolation and the output of described switching value signal with control module 130, and according to the dc signal of simulating the rotation speed of fan signal from the steering order of control module 130 to the output of fan vibration monitoring device.
The principle of work of the functional tester of the wind-powered electricity generation unit vibration monitoring device that the utility model is provided is introduced below.
In the present embodiment, can adopt the coupling arrangement of needle-bar frock, simplify installation testing operation for existing wind-powered electricity generation unit vibration monitoring device as described functional tester and wind-powered electricity generation unit vibration monitoring device.
Since the vibration signal that its sensing unit need be sensed of wind-powered electricity generation unit vibration monitoring device with just can carry out relevant monitoring after tach signal converts electric signal to, therefore, wind-powered electricity generation unit vibration monitoring device functional tester of the present utility model is by signal output unit 100 with leave the unit 140 aweather voltage signal and the dc signal of group of motors vibration monitoring device output simulation wind-powered electricity generation unit vibration and rotating speed.Wherein, the voltage signal degree of amplitude modulation of simulation wind-powered electricity generation unit vibration is 0.1～5V, is 5V with the amplitude peak of each bear vibration of the wind-powered electricity generation unit corresponding voltage signal that is directly proportional; Be used to simultaneously to simulate that two dc signal degree of amplitude modulation of tach signal are 0.1～24V before and after the wind-powered electricity generation unit vibration, the degree of amplitude modulation of promptly corresponding wind-powered electricity generation generating unit speed signal is 1r/min～2000r/min.
Adopting the pwm signal output circuit is that 6 tunnel vibration voltage signals from wind-powered electricity generation unit vibration monitoring device tester to wind-powered electricity generation unit vibration monitoring device all are digital forms as an advantage to wind-powered electricity generation unit vibration monitoring device analog vibration voltage signal output unit, need not to carry out digital-to-analog conversion.Allow signal remain digital form and noise effect can be dropped to minimum.
When the slip-stick artist of administration and supervision authorities or operator need carry out functional test to wind-powered electricity generation unit vibration monitoring device, use host computer that test command is sent to wind-powered electricity generation unit vibration monitoring device functional tester.After described functional tester received described order by communication unit 110, the simulator program that calls the fan vibration that is stored in the program storage 121 and rotating speed through control module 130 generated and is used for control signal output unit 100 and leaves unit 140 and will simulate the vibration and the tach signal of wind-powered electricity generation unit and export wind-powered electricity generation unit vibration monitoring device to.After the vibration of the simulation wind-powered electricity generation unit that wind-powered electricity generation unit vibration monitoring device meeting basis receives and tach signal are made corresponding processing, feedback data is sent to described functional tester, by described functional tester feedback data is sent to host computer through communication unit 110, whether simulation wind-powered electricity generation unit vibration that host computer sends by more described functional tester and the monitor signal in tach signal and the wind-powered electricity generation unit vibration monitoring device feedback data, it is normal to judge the work of wind-powered electricity generation unit vibration monitoring device.For example, the voltage and the rotating speed of the wind-powered electricity generation unit vibration amplitude correspondence by the simulation of described tester are respectively 4V and 2000r/min, suppose that the wind-powered electricity generation unit vibration frequency under this rotating speed belongs to alarm range, if the monitor signal in the wind-powered electricity generation unit vibration monitoring device feedback data is an alerting signal, just can judge that wind-powered electricity generation unit vibration monitoring device is working properly, on the contrary then undesired.
