The wireless transmission pressure acquisition device adopts a wireless transmission mode, does not need the connection of cables, can perform remote transmission, has low power consumption, and solves the problems existing due to excessive cables in the prior art.
Description
Technical field
The utility model relates to the device that carries out pressure data wireless collection and transmission in a kind of industry spot, relates in particular to a kind of radio transmitted pressure collector, applicable to industries such as oil, chemical industry, space flight, tobaccos.
Background technology
In the prior art, in order to realize the long-distance transmissions of sensor signal, general pressure transducer is pressure signal to be converted to electric signal directly be sent to transmitter, transmitter amplifies electric signal again, so that supply the signal source of distant place measurement and control, mode signal output commonly used has 4-20mA electric current loop or 0-5V voltage signal by the signal cable transmission signals.
Adopt aforesaid way mainly to have following problem: one, the existing a lot of cables of teletransmission mode needs, and need power to transmitter, use very inconvenience.Two, along with the increasing gradually of collection in worksite parameter, on-site cable is more and more, causes problems such as difficult wiring, because to be used for the cable of information transmission more, causes transmitter mistake to occur to the information of on-site data processing control center easily simultaneously.Three, site work environment is abominable, causes cable to damage easily, and power consumption is big, not only causes image data discontinuous but also increased acquisition cost.
The utility model content
The purpose of this utility model is to overcome the problems referred to above that exist when having the pressure sensor data collection now, a kind of radio transmitted pressure collector is provided, the utility model adopts wireless transmission method, do not need cable to connect, and can carry out long-distance transmissions, low in energy consumption, solved in the prior art because the too many problems referred to above that exist of cable.
For achieving the above object, the technical solution adopted in the utility model is as follows:
A kind of radio transmitted pressure collector, it is characterized in that: pressure transducer is gathered pressure signal, the pressure signal that collects is transferred to microprocessor after being converted to digital signal by A/D converter, after microprocessor is given radio-frequency (RF) circuit module with digital data transmission, after amplifying radiofrequency signal, amplifying circuit sends to receiver.
Described amplifying circuit amplifies radiofrequency signal after antenna transmission arrives receiver.
Described amplifying circuit amplifies radiofrequency signal after antenna and repeater send to receiver.
Adopt advantage of the present utility model to be:
One, adopt the wireless mode transmission between radio transmitted pressure collector and the data processing control center, do not need cable, and pressure transducer do not need to the transmitter power supply for not with the pressure transducer of transmission circuit, easy to use.
Two, in the utility model, pressure transducer can turn-off the pressure transducer feed circuit when image data is not in the free time, make pressure transducer be in waiting status completely, common high-energy battery just can satisfy the on-the-spot test needs, and is low in energy consumption, and acquisition cost is lower.
Can adopt repeater when three, between transmission range is greater than 500m or radio transmitted pressure collector and data processing control center large-scale barrier being arranged, the number according to the different choice repeater of transmission range is not subjected to the restriction of transmission range, uses flexibly.
Four, the utility model is changed into wireless transmission with data collection and transfering system from wire transmission, has solved that the information transmission cable is more, field wiring is difficult, cable damages easily, transmitter problems such as mistake occur to the information of on-site data processing control center.
Five, the utility model is installed in the position that needs image data, cooperate on-the-spot test equipment can collect real-time pressure data accurately and efficiently, can reduce the power consumption of battery significantly, battery can use 6 months to 2 years under the low power consumption standby mode, prolonged the on-site data gathering System production time, solved effectively and can't frequently change battery or this difficult problem of charging repeatedly in the site work process, reduced cost simultaneously.

Be labeled as among the figure: 1, pressure transducer, 2, safety cock, 3, A/D converter, 4, single-chip microcomputer, 5, the SPI interface, 6, radio-frequency (RF) circuit module, 7, antenna, 8, battery, 9, power management module.
Embodiment
In the radio transmitted pressure collector, the radio transmitted pressure collector is gathered the measuring point pressure signal, the pressure signal that collects is transferred to microprocessor after being converted to digital signal by A/D converter 3, after microprocessor is stored and is shown, again digital signal is transferred to radio-frequency (RF) circuit module 6 by SPI interface 5, after amplifying circuit amplifies radiofrequency signal, send to receiver, finish transport communication with data processing control center.
The radio transmitted pressure collector comprises that mainly pressure transducer 1, safety cock 2, A/D converter 3, the low-power scm 4 of not being with transmission circuit are microprocessor, radio frequency circuit module 6 and external comprehensive gain antenna 7, common lithium battery 8, in whole wireless data transmission, adopt common lithium battery 8 to become feed signals so that 4-20mA to be provided for power management module 9 power supplies.Amplifying circuit amplifies radiofrequency signal after antenna 7 sends to receiver.When transmission range was far away, amplifying circuit amplified radiofrequency signal after antenna 7 and repeater send to receiver.
The utility model mainly is to finish sensor signal input, ADC analog to digital conversion, collection and record sensing related data, and by wireless radio frequency mode the information wireless that collects is sent to receiver.When selecting intelligent pressure sensor for use, then output signal is a digital signal, does not need to carry out the AD conversion again.
Adopt the wireless mode transmission between the utility model and the data processing control center, pressure transducer 1 can turn-off pressure transducer 1 feed circuit when image data is not in the free time, makes pressure transducer 1 be in waiting status completely.When long transmission distance, can adopt repeater as transmission range when between 500m or collector and the data processing control center large-scale barrier being arranged, the number according to the different choice repeater of transmission range is not subjected to the restriction of transmission range in theory.Be installed in the position that needs image data, cooperate on-the-spot test equipment can collect real-time pressure data accurately and efficiently, can reduce the power consumption of battery significantly, battery can use 6 months to 2 years under the low power consumption standby mode, prolonged the on-site data gathering System production time, solved effectively and can't frequently change battery or this difficult problem of charging repeatedly in the site work process, reduced cost simultaneously.
Obviously; those of ordinary skill in the art is according to technical know-how of being grasped and customary means; according to above said content, can also make the various ways that does not break away from the utility model basic fundamental thought, these pro forma conversion are all within protection domain of the present utility model.
