Description
Technical field
The present invention relates to a kind of noise-measuring system, more particularly to a kind of Substation Station circle noise-measuring system.
Background technology
High-voltage alternating substation audible noise measuring is included to substation's Main Noise Sources（Main transformer, reactor, ventilation
Wind turbine etc.）, Work places and stand boundary's audible noise measurement.At present, generate and make an uproar in 500kV and 1000kV substations Work places
The charging equipment of sound is numerous and bulky, and Work places acoustic environment is complicated, is unfavorable for operating personnel's physical and mental health and equipment peace
Row for the national games, there is an urgent need for carrying out comprehensive measurement analysis to noise, to realize the accurate control to Work places noise.For operation field
The phenomenon that charging equipment is numerous and bulky during institute's noise testing, existing solution are using self-control extension rod and extension electricity
Cable.Microphone is connected with sound level meter host using extension cable, and the hollow parts of extension cable from self-control extension rod run through into.
Self-control extension rod is combined by simple grafting, is easily rocked when reaching eminence, can be shaken microphone, and be unable to control probe
Direction prevents probe from face noise-producing source measurement result to be caused to be not allowed.It can only by hand be controlled by tester in microphone direction
System, can not realize the comprehensive measurement of noise.
The content of the invention
The present invention provides a kind of comprehensive noise-measuring systems for substation's Work places, solve existing measurement
The technical issues of device can not ensure noise testing accuracy and can not realize noise comprehensive measurement.
The present invention is to solve more than technical problem by the following technical programs：
A kind of comprehensive noise-measuring system for substation's Work places, including wireless signal receiver, sound level meter
Host, stepper motor, stepping-motor remote controlled device and noise testing elevating lever, stepper motor are connected electrically in stepping-motor remote controlled device
Together, installing plate is fixedly installed on the top of noise testing elevating lever, is provided with power module and wireless communication on a mounting board
Number transmitter, is provided with stepper motor on the top of installing plate, is connected on the output shaft stretched out vertically upward of stepper motor
There is sound level meter probe, sound level meter probe links together with wireless signal transmitter.
The bottom of noise testing elevating lever is fixed with three-legged support.
The comprehensive measurement of the achievable substation's Work places noise of the present invention carries for the accurate control of Work places noise
Accurate data is supplied.
Description of the drawings
Fig. 1 is the structure diagram of the present invention.
Specific embodiment
The present invention is described in detail below in conjunction with the accompanying drawings：
A kind of comprehensive noise-measuring system for substation's Work places, including wireless signal receiver 6, sound level meter
Host 7, stepper motor 3, stepping-motor remote controlled device 8 and noise testing elevating lever 1, stepper motor 3 and 8 electricity of stepping-motor remote controlled device
It links together, is fixedly installed installing plate 2 on the top of noise testing elevating lever 1, power module is provided on installing plate 2
And wireless signal transmitter, the top of installing plate 2 is provided with stepper motor 3, it is defeated in stretching out vertically upward for stepper motor 3
Sound level meter probe 4 is connected on shaft, sound level meter probe 4 links together with wireless signal transmitter.
The bottom of noise testing elevating lever 1 is fixed with three-legged support 5.
According to the device height of substation's Work places and situation on the spot, noise testing elevating lever 1 is selected, general noise is surveyed
Amount elevating lever 1 is made of more piece, and sound level meter probe 4 is made to reach designated position after rise, starts noise testing.Tester holds
Sound level meter host, operation stepping-motor remote controlled device 8 make 4 rotation of sound level meter probe, carry out the 360 degrees omnidirection measurement of noise.Sound
The noise signal that grade meter probe 4 detects can be emitted by wireless signal transmitter, and reception of wireless signals module 6 is transmitted to after receiving
Sound level meter host 7 is shown on the liquid crystal display of sound level meter host 7, and survey crew can observe and record noise data.
