Description
Technical field
The invention belongs to pressure transmitter technical field, relate to that signal strengthen the wireless pressure pick-up of transmission
Device.
Background technology
Pressure transmitter refers to export the pressure sensor for standard signal, is that one kind receives pressure variations and turned in proportion
It is changed to the instrument of standard output signals.It can turn the physical pressure such as gas that load cell is experienced, liquid parameter
Become the electric signal (such as 4~20mADC) of standard, to supply the progress of the secondary meters such as indicator alarm, recorder, adjuster
Measurement, instruction and procedure regulation.Pressure transmitter is usually used in the fields such as oil well, water conservancy, positioned at remote ground, it is necessary to by long-range
Mobile communications network in transmission means outwards transmits data.The signal such as collected is more fuzzy, and letter is easily caused in processing
Number gradually weaken even lose, the signal transmitted in addition is also unstable, has a strong impact on the continuous collecting of data.
The content of the invention
To solve the above problems, the invention discloses enhanced wireless pressure transmitter, it is amplified in signal acquisition
Handle, and carry out the enhancing of signal again before being wirelessly transferred.
In order to achieve the above object, the present invention provides following technical scheme：
Enhanced wireless pressure transmitter, including power supply part, processor, pressure sensor, amplifying circuit, AD conversion circuits,
Memory, 3G/4G communication modules, Signal Booster, antenna, the pressure sensor, amplifying circuit, AD conversion circuits connect successively
Connect, the processor is connected with AD conversion circuits, 3G/4G communication modules respectively, Signal Booster respectively with 3G/4G communication modules
Connected with antenna, the power supply part is each power elements in transmitter, and the pressure sensor is used to gather pressure simulation letter
Number, the amplifying circuit is used to be amplified the signal that pressure sensor collects processing, and the AD conversion circuits are used for will
The analog signal of amplifying circuit output is converted into data signal and transmitted into processor, and the Signal Booster is used for signal
Strengthened.
Further, in addition to temperature-compensation circuit, the numeral that the temperature-compensation circuit exports to AD conversion circuits are believed
Number carry out temperature-compensating.
Further, the power supply part includes battery.
Further, in addition to short range wireless transmission module.
Further, the short range wireless transmission module includes at least one of WIFI module, bluetooth module.
Compared with prior art, the invention has the advantages that and beneficial effect：
Enhanced wireless pressure transmitter provided by the invention can first carry out enhanced processing after signal acquisition so that after signal
Stronger signal intensity is still kept in continuous processing, in addition by first passing through signal enhancing during mobile communication module correspondence with foreign country
Device keeps signal intensity, avoids dropout in transmitting procedure to externally being sent again after signal enhancing.
Brief description of the drawings
Fig. 1 is enhanced wireless pressure transmitter configurations block diagram provided by the invention.
Embodiment
Technical scheme provided by the invention is described in detail below with reference to specific embodiment, it should be understood that following specific
Embodiment is only illustrative of the invention and is not intended to limit the scope of the invention.
Enhanced wireless pressure transmitter, as shown in figure 1, including power supply part, processor, pressure sensor, amplification electricity
Road, AD conversion circuits, memory, 3G/4G communication modules, Signal Booster, antenna, wherein pressure sensor, amplifying circuit, AD
Conversion circuit is sequentially connected, and processor is connected with AD conversion circuits, 3G/4G communication modules respectively, Signal Booster respectively with 3G/
4G communication modules connect with antenna.Power supply part is each power elements in transmitter, it is preferred to use battery.Pressure sensor is used
In collection pressure simulation signal, amplifying circuit is used to be amplified the signal that pressure sensor collects processing, AD conversion electricity
Road is used to the analog signal of amplifying circuit output is converted into data signal and transmitted into processor, and Signal Booster is used for pair
Signal is strengthened.In addition, this transmitter may also include short range wireless transmission module, short range wireless transmission module includes
At least one of WIFI module, bluetooth module.
As an improvement, transmitter of the present invention should also include temperature-compensation circuit, temperature-compensation circuit is connected with processor, is used
Data signal after pressure sensor is gathered and gone out carries out temperature-compensating.
In enhanced wireless pressure transmitter, pressure sensor collection pressure simulation data, amplifying circuit enters to the data
The signal that pressure sensor collects can be amplified, make it locate behind by being transmitted after row amplification to AD conversion circuits, amplifying circuit
Stronger signal intensity is still kept during reason.Analog signal is converted into data signal by AD conversion circuits, the data signal
Trip temperature compensation deals of going forward side by side are transmitted into processor.Data in processor are stored by being conveyed into memory.
When data need to transmit by 3G/4G communication modules, strengthened by Signal Booster, then outwards transmitted by antenna,
Very strong communication signal strength can be kept.In addition, transmitter can also be by short range wireless transmission module with showing in the present invention
Field router or repeater carry out signal transmission.
Technological means disclosed in the present invention program is not limited only to the technological means disclosed in above-mentioned embodiment, in addition to
Formed technical scheme is combined by above technical characteristic.It should be pointed out that for those skilled in the art
For, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as
Protection scope of the present invention.
