Description
Technical field
The present invention relates to technical field of pressure detection, specifically a kind of wireless pressure detecting device.
Background technology
Pressure detection is very general in the application of the every field such as daily life, industrial and agricultural production.Pressure detection in the market is a bit taked artificial reading and is recorded the pressure data recorded, some is the automatic detected pressures data of wire laying mode, but because a lot of industrial environment is quite complicated, pressure detection point has a very wide distribution, distance, if adopt existing wired pressure detector, not only trouble is installed, cost is high, and system is doted on greatly, be unfavorable for applying on a large scale.
Summary of the invention
The object of the present invention is to provide a kind of easy for installation, cost is low and result of use is good wireless pressure detecting device.
The technical solution adopted for the present invention to solve the technical problems is: wireless pressure detecting device comprises the pressure transducer connected successively, Circuit tuning, A/D converter, microprocessor and radio-frequency (RF) receiving and transmission module, also be connected to serial port module on the microprocessor, radio-frequency (RF) receiving and transmission module is connected to antenna, described pressure transducer, Circuit tuning, A/D converter, microprocessor and radio-frequency (RF) receiving and transmission module are connected with power supply respectively powers, described microprocessor comprises MSP430 chip, described radio-frequency (RF) receiving and transmission module comprises NRF905 less radio-frequency and to get into the frame of mind for work chip, described serial port module comprises data-interface, be mainly used in connecting copy reading equipment, write device or input equipment, information set by running for input microprocessor and data upload download etc., described power supply comprises dry cell.
The invention has the beneficial effects as follows, the present invention has the advantages such as practical, usable range is wide, accuracy rate is high, good reliability, life-span are long, and easy to install, and cost is low, easy to utilize.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
With regard to accompanying drawing 1, wireless pressure detecting device of the present invention is described in detail below below.
As shown in Figure 1, wireless pressure detecting device of the present invention comprises the pressure transducer connected successively, Circuit tuning, A/D converter, microprocessor and radio-frequency (RF) receiving and transmission module, also be connected to serial port module on the microprocessor, radio-frequency (RF) receiving and transmission module is connected to antenna, described pressure transducer, Circuit tuning, A/D converter, microprocessor and radio-frequency (RF) receiving and transmission module are connected with power supply respectively powers, described microprocessor comprises MSP430 chip, described radio-frequency (RF) receiving and transmission module comprises NRF905 less radio-frequency and to get into the frame of mind for work chip, described serial port module comprises data-interface, be mainly used in connecting copy reading equipment, write device or input equipment, information set by running for input microprocessor and data upload download etc., described power supply comprises dry cell.
Principle of work of the present invention is, the pressure signal of pressure transducer Test Field, and the pressure signal detected is sent to Circuit tuning compensate adjustment process, then export from Circuit tuning, convert data-signal to through A/D converter and flow to microprocessor, microprocessor carries out recognition coding process to the data-signal received, and give corresponding time data signal, then, total data signal is packed and is sent to radio-frequency (RF) receiving and transmission module in real time by microprocessor together, in the frequency of operation segment limit of regulation, collection control receiving center is sent in time again by radio-frequency (RF) receiving and transmission module and antenna, and wait the other side is received the confirmation signal beamed back by microprocessor after being sent, fail to report to avoid loss of data, if when failing to obtain confirmation signal, microprocessor will repeat to send set point number by radio-frequency (RF) receiving and transmission module and antenna again, when not yet obtain confirmation signal then microprocessor be automatically restored to normal condition and wait for wake up next time, when acquisition confirmation signal etc. then microprocessor will proceed to park mode immediately, wait for and waking up next time.
The frequency of operation section that described radio-frequency (RF) receiving and transmission module and antenna use comprises the one in 433MHz, 915MHz, 2450MHz.
