Description
Technical field
This utility model relates to noise measuring field, particularly relates to a kind of portable noise level monitor.
Background technology
Noise monitoring and detection are more and more important in people's daily life, and many important events are all it can be seen that the publicity of " quiet please " or " thank you for keeping your voices down " or the like identifies.Moreover, plant siting is set up factories and will be considered the pollution of Noise upon Environment, all needs to take certain noise reducing efforts.
China Patent Publication No. is that the utility model of CN201320243565.3 discloses a kind of noise measuring instrument, technical scheme includes housing, pick up, processor, alarm, display and power supply, processor is arranged in housing, pick up is connected with processor, in order to receive and to detect the noise decibel in environment；Display is connected with processor, is arranged at the outside of described housing, in order to show noise figure；Alarm is connected with processor, when noise reaches certain decibel, then carries out voice reminder；This noise level monitor can play and preferably monitor and prompting function, but no data writing function, it is necessary to improve.
Utility model content
This utility model purpose be develop a kind of tape recording function exportable noise data portable noise level monitor.
This utility model is achieved by the following technical solution:
A kind of portable noise level monitor, including the cavity being wrapped to form by housing, also include processor and the signal storage being arranged on inside cavity, described signal storage signal is stored in end and is electrically connected with processor, and signal output part is electrically connected with LCDs, AC signal output interface by mode conversion key.
Preferably, also include the pick up being arranged on housing upper, in described pick up, be additionally provided with amplifier.
Preferably, also include function button district, be arranged on below LCDs, the function button that described function button district is provided with at least including mode conversion key, maximum readings locking key and A/C value shift key, upper downturning key.
Preferably, described maximum readings locking key is arranged between mode conversion key and AC signal output interface.
Preferably, described LCDs is at least more than 5 inches.
Preferably, it is also equipped with sponge ball above described pick up.
Preferably, also including the accumulator being arranged in cavity, described accumulator is 3000 milliamperes of lithium batteries, and accumulator side is provided with USB interface.
The beneficial effects of the utility model are:
1, this utility model by shell, LCDs, function button, pick up, AC signal output interface, signal storage, accumulator with the use of, its feature richness, simple in construction, easy to carry, it is possible to when noise sends, the size of noise to be measured and can store and export related data.
2, this utility model is provided with mode conversion key, is changed by it, noise measuring data can be shown on liquid crystal display or output data are to movable storage device；Being provided with maximum readings locking key, the maximum noise value monitored can be done discrete data output, enhance the motility of equipment in different periods, extended equipment storage function.
3, this utility model is also additionally arranged amplifier in pick up, can be with the noise of the low decibel of effective monitoring, wide accommodation.
4, in this utility model, accumulator is 3000 milliamperes of lithium batteries, is provided with USB interface in accumulator side, can be that accumulator is charged by USB interface, it is also possible to the data of measurement are downloaded to USB flash disk, computer etc., improves the sharing functionality of device data.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation；
Fig. 2 is this utility model embodiment schematic diagram.
Detailed description of the invention
Below in conjunction with the accompanying drawings and this utility model is described further by detailed description of the invention.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Fig. 1～2, a kind of portable noise level monitor, including the cavity being wrapped to form by housing 1, also include processor and the signal storage being arranged on inside cavity, processor use 16 high-performance, super low-power consumption MSP430F149 chip as central processing unit, processing speed is fast, and efficiency is high；Signal storage signal is stored in end and is electrically connected with processor, and signal output part is electrically connected with five inch liquid crystal display screens 3 by mode conversion key 4 one tunnel, and a road is electrically connected with AC signal output interface 8.
In the present embodiment, also include the pick up 2 being arranged on housing 1 top, in pick up 2, be additionally provided with amplifier, strengthen for the signal when low decibel value.
In the present embodiment, also include function button district, being arranged on below LCDs 3, described function button district is provided with the function key including mode conversion key 4, maximum readings locking key 7 and A/C value shift key 5, upper downturning key 6, on & off switch, operation key, stop key.
Operation principle of the present utility model is: lithium battery provides the electric energy that whole system is run, the treated device of noise signal that pick up 2 gathers is automatically stored to signal storage after processing, if desired for, line function can be switched so that it is the signal real time reaction of detection is to LCDs 3 by mode conversion key 4.In addition, for ease of the maximum noise monitored in different periods value being done discrete data output, being also provided with maximum readings locking key 7, and being prefixed peak value processing routine within a processor, by the maximum readings locking key 7 of switching, the maximum noise value in different periods can be done discrete data output.
It is to explanation of the present utility model that embodiment that above is describes, it not to restriction of the present utility model, this utility model limited range sees claim, and in the case of this utility model basic conception, this utility model can make the amendment of other form.
