Abstract

The utility model relates to an ammeter with infrared distance induction, which comprises a power circuit, an infrared distance induction module, a single chip microcomputer minimum system and an LCD display module, wherein output signals of the power circuit are transmitted to the infrared distance induction module and the single chip microcomputer minimum system; two-way data communication is carried out between the infrared distance induction module and the single chip microcomputer minimum system; and output signals of the single chip microcomputer minimum system are sent to the LCD display module. According to the full-digital voltmeter and the full-digital ammeter, the corresponding values of measured signals are displayed on the LCD display module through data acquisition, number system processing and control of the single chip microcomputer minimum system, the values are sent to a computer by using a serial port and are displayed in a proper waveform, the measurement control precision is high, and high reliability and stability are facilitated; and as the infrared distance induction module is adopted for controlling the LCD display module, the purpose of saving energy is achieved, and the service life of the LCD is improved.

Description

A kind of reometer of answering with infrared distance perspective

Technical field

The utility model relates to electronic circuit field, particularly be a kind of reometer of answering with infrared distance perspective.

Background technology

Along with the development of electronic technology, in digitizing, intellectuality, science and technology, turn to main today.Digital voltage, reometer have become the main direction of voltage, reometer design, occupy very important position in current voltage, current measurement system.

Utility model content

The purpose of this utility model is to provide a kind of reometer of answering with infrared distance perspective.

The utility model solves the technical scheme that its technical matters adopts: a kind of reometer of answering with infrared distance perspective, include power circuit, infrared apart from induction module, single-chip minimum system and LCD display module, the output signal of described power circuit is transferred to infrared apart from induction module and single-chip minimum system, described infrared apart from induction module and single-chip minimum system bidirectional data communication, the output signal of described single-chip minimum system is sent to LCD display module.

It is control core that described single-chip minimum system adopts STM32F101RBT6 chip.

Described infrared apart from induction module employing pyroelectric sensor process chip BISS0001 collection signal.

Described LCD display module is LCD LCDs.

By adopting above-mentioned technical scheme, the beneficial effects of the utility model are: digital voltage of the present utility model, reometer by measured signal by data acquisition, numeral system is processed, by single-chip minimum system, control and finally make its analog value show on LCD display module, and utilize serial ports to send to computing machine simultaneously, and show with in good time waveform, and the utility model is by the control to the judgement of measured signal and range selector, the range of having realized eight gears in high-precision meter regulates automatically, not only guarantee the measuring accuracy of weak signal but also taken into account the measurement range of strong signal, simultaneously, overcome at the voltage that adopts traditional manual selection range gear, during reometer, forget conversion gear and cause the decline of instrument measurement precision or the danger of damage, SCM Based intelligent comprehensive instrument is based on intellectuality, digitizing, the design concept of networking New Generation of Intelligent instrument, adopt intelligent conditioning, dexterous bus, industrial network, liquid crystal display, electron storage technology, comprehensive indicatior table, regulation meter, integrating meter and recorder function, there is high measurement control accuracy, the feature of high reliability stability, the utility model adopts infrared distance perspective to answer module controls LCD display module, both reached the object of saving the energy, can improve again LCD serviceable life.

Embodiment

Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.

As shown in Figure 1 and Figure 2, a kind of reometer of answering with infrared distance perspective of the present utility model, include power circuit, infrared apart from induction module, single-chip minimum system and LCD display module, the output signal of described power circuit is transferred to infrared apart from induction module and single-chip minimum system, described infrared apart from induction module and single-chip minimum system bidirectional data communication, the output signal of described single-chip minimum system is sent to LCD display module.

Power circuit by one independently Switching Power Supply produce one+12V voltage, through obtain+5V of overcommutation ,+3.3V voltage, offer all parts, guarantee the normal work of system.

It is control core that described single-chip minimum system adopts STM32F101RBT6 chip, STM32F103RBT6 chip is used 32 Dun RISC kernels of high-performance ARM Cortex-M3, frequency of operation is 72MHz, built-in high-speed memory (up to the flash memory of 128K byte and the SRAM of 20K byte), abundant enhancing I/O port and the peripheral hardware that is connected to two APB buses, can work in the temperature range of-40 ℃ to+105 ℃, supply voltage+2.0V is to+3.6V, and power consumption is very low.In this reometer design system with infrared control, it is controlled as core, and its outside is added with 8M crystal oscillating circuit, and stable time clock is provided, and synchronous miscellaneous part, makes working properly.

Described infrared apart from induction module employing pyroelectric sensor process chip BISS0001 collection signal, this chip is that a sensor with superior performance is processed integrated circuit, be equipped with pyroelectric infrared switch, warning human body heat-releasing electric transducer that pyroelectric infrared sensor and a small amount of outward element just can form passive type, have antijamming capability strong, inside is provided with timer and blocking time timer time delay.In native system, be mainly to detect by pyroelectric infrared sensor the infrared radiation sending from human body, device is changed into electric signal output, control the backlight open of LCD display module, if people leaves simultaneously, the infrared radiation that human body sends do not detected, when setting-up time arrives, just close LCD display module backlight, seem humanized, also reduced the waste of the energy.

Described LCD display module is LCD LCDs, and its quality is good, more diversified than traditional charactron demonstration, can not bring serious consequence because of the demonstration fault of certain section, more directly perceived, convenient, reliable.

Above-described is only a preferred embodiment of the present utility model, can not limit the scope that the utility model is implemented, and every equalization of doing according to the utility model claim changes and decorates, and all should still belong in the scope that the utility model contains.
