Description
Technical field
The present invention relates to substation equipment detection alarm device, be specially a kind of ultrasound wave detection and localization alarm for transformer station.
Background technology
Along with the standardization of the every management of electric power enterprise, the maintenance detection management of power equipment also becomes more and more stricter, research finds, any electrical equipment is in operation, owing to being subject to the effect of exchange current, there is various sound and vibration in capital, comprising hearing noise and sound wave, these sound and vibration are specific to operational outfit, it is a kind of feature of indication equipment running status, so, experienced staff often can position judgement according to the acoustic wave character of converting equipment to its fault, but, some are in the high-tension apparatus of specific position, such as superelevation nip or altitude plant, do not allow people close under normal operating conditions, therefore, equipment failure cannot be predicted or locate, very unfavorable to the detection of its accident defect.
Especially between regular turn(a)round, technician cannot accurate characterization high pressure time phenomenon of the failure, this problem is never resolved breakthrough, and can only manually infer by rule of thumb, large area is exchange device more.For the location of abnormal sound, particularly ultrasonic signal, be only difficult to accomplish with ear.So how to carry out auditory localization just seem particularly important under noisy environment, because the periodic test of the running status to electric equipment and odd test require more and more higher, more and more thinner, traditional listening argues that position has been difficult to solve site technology problem up hill and dale; Research finds, mostly transformer station is to be in the environment that has multiple noise, is wherein power frequency acoustical signal mostly, when equipment breaks down, will inevitably supervene ultrasonic signal, and these ultrasound waves and power frequency acoustical signal are mingled in the environment sound.But transformer station is again simultaneously the more special place of an environment, and be do not allow people near equipment under substation operation state, belong to hazardous location, duration of work forbids that personnel are close.And at present, the lookup method intelligence degree of the abnormal ultrasound source of transformer station is very low, cannot search ultrasound source fast and accurately, fix a breakdown.
Summary of the invention
The present invention cannot search to solve existing transformer station the problem that ultrasound source fixes a breakdown fast and accurately, provides a kind of ultrasound wave detection and localization alarm for transformer station.
The present invention adopts following technical scheme to realize: for the ultrasound wave detection and localization alarm of transformer station, comprise single-chip microcomputer, single-chip microcomputer has connected amplifier, amplifier is connected to ultrasonic transmission device, single-chip microcomputer has connected filtering circuit, filtering circuit is connected to ultrasonic probe, ultrasonic receiver, single-chip microcomputer has connected temperature sensor, single-chip microcomputer has connected signal alarm, single-chip microcomputer is also connected to imaging signal processing circuit, imaging signal processing circuit is connected to digital indicator, single-chip microcomputer is specially AVR programmable microcontroller, the transmitting driving circuit that ultrasonic transmission device is made up of ultrasound transmitting transducer and multiple phase inverter is formed, ultrasonic probe, ultrasonic receiver is made up of ultrasound wave receiving transducer and infrared ray detection reception circuit integrated chip.
In use procedure, the single-chip microcomputer square-wave signal preset needed for port output ultrasonic wave transducer, utilize the return signal that outer middle fracture monitoring ultrasound wave receiving circuit exports, on the one hand the return signal received is converted to general-purpose digital signal subsequently, the outside digital indicator connected is transferred to by imaging signal processing circuit, on the other hand the criticality alarm value that digital signal and internal processes store is carried out size to compare, if meet or exceed criticality alarm value, perform interruption subroutine, and alerting signal is transferred to external signal alarm, thus realize warning function.Imaging signal processing circuit can receive the display of prime module transfer, the i.e. sound intensity mapping signal of ultrasound wave reception, this signal is shown with the pixel of different colours on its digital indicator connected by threshold circuit, thus special ultrasonic wave point can be demonstrated by the colour circle difference on display, realize the function that display differentiates.The external pin of single-chip microcomputer exports pulse train as drive input signal, an electrode of ultrasonic transducer is delivered on signal one tunnel after one-level reverser, another electrode of ultrasonic transducer is delivered on another road after two-stage reverser, by this form of recommending square-wave signal is added to the two ends of ultrasonic transducer, hyperacoustic emissive porwer can be improved; Receiving chip is infrared ray detection reception circuit integrated chip, has good sensitivity and stronger antijamming capability; By suitably changing the size of output capacitor, sensitivity and the antijamming capability of receiving circuit can also be changed.The signal of receiving chip, circuit after filtering before being transferred to single-chip microcomputer, and filtering circuit is the two-stage filtering and amplifying circuit of R-C coupling form.
Above-mentioned sound digital indicator, imaging signal processing circuit, signal alarm, single-chip microcomputer, amplifier, ultrasonic transmission device, temperature sensor, filtering circuit, ultrasonic probe, ultrasonic receiver etc. are existing product, and its circuit design and control mode are that those skilled in the art easily realize.
Beneficial effect of the present invention is as follows: the present invention utilizes the supersonic sounding device of appropriate design, achieves and searches ultrasound source fast and accurately in transformer station thus fix a breakdown.The invention provides a kind of safe, reliable, technological means of being suitable for, signals collecting accurately, data transmission rapidly, accuracy rate is high, simultaneously lower for the cost of device and antijamming capability is high, simple and practical, be easy to safeguard.The present invention is located by ultrasonic listening, effectively solving people ear cannot transformer station's abnormal vibrations of consciousness and location, under guaranteeing that equipment operates in normal state, before there is operation troubles in equipment, find problem and solve, prevent trouble before it happens, effectively improve the work efficiency that station is safeguarded.
