Background technology
In the production run in oil field in the past, operating personnel determine the size of pressure by the gauge outfit numerical value that reads the pointer mechanical manometer that is installed on the pipeline, operating personnel need the data of on-the-spot each gauge outfit of manual record, for the occasion that a large amount of pointer mechanical manometers are arranged, reading and writing down of pressure gauge numerical value certainly will bring loaded down with trivial details workload to operating personnel, and can cause the accuracy of data to lower because of different operating personnel's the error that reads, this have brought very big difficulty for the data analysis of back.
The utility model content
Technical problem to be solved in the utility model is that a kind of easy, effective outdoor explosion-proof pressure harvester will be provided.
In order to solve above technical matters, the utility model provides a kind of outdoor explosion-proof pressure harvester, this pressure acquisition device is provided with controlled processing unit, other is provided with pressure sensor unit, the temperature sensor unit is connected with controlled processing unit with power supply unit, pressure sensor unit is gathered ducted pressure data, the temperature sensor unit is gathered the data of environment temperature and is delivered to controlled processing unit, after controlled processing unit converts the pressure data of gathering the pressure value of user's demarcation to, send by wireless transmitting unit, simultaneously with data storage in data storage cell.
Described power supply unit is provided with magnetic induction switch, and this magnetic induction switch is subjected to the control of the magnetic element on the hand-held pressure receiving trap.
Described wireless transmitting unit adopts the 2.4G wireless telecommunications chip of super low-power consumption, realizes the transmission of pressure signal and pressure parameter.
Described pressure sensor unit adopts the device of the pressure transducer of low-voltage, low-power consumption as data acquisition.
The utility model is used for the force value of collection site, when hand-held pressure receiving trap when the pressure acquisition device, power turn-on, by gathering 0 to 100 millivolt voltage signal of pressure sensor unit, convert 0 or 2.5 volt of voltage to, the pressure value that becomes voltage transitions the user to demarcate sends by wireless transmitting unit then.
Superior effect of the present utility model is: the utility model adopts the battery of 3.6V high reliability, wide temperature, in case when needing image data, power turn-on carries out the collection of pressure data, is in the state of low-power consumption at ordinary times; Easy to use, effective.

Embodiment
See also shown in the accompanying drawing, the utility model will be further described.
As depicted in figs. 1 and 2, the utility model provides a kind of outdoor explosion-proof pressure harvester, this pressure acquisition device is provided with controlled processing unit 1, other is provided with pressure sensor unit 2, temperature sensor unit 2 is connected with controlled processing unit 1 with power supply unit 3, pressure sensor unit 2 is gathered ducted pressure data, the data that environment temperature is gathered in temperature sensor unit 3 are delivered to controlled processing unit 1, after controlled processing unit 1 converts the pressure data of gathering the pressure value of user's demarcation to, send by wireless transmitting unit 5, simultaneously with data storage in data storage cell 11.
Described power supply unit 4 is provided with magnetic induction switch, is subjected to the magnetic element gauge tap on the hand-held pressure receiving trap.
As shown in Figure 4,Described wireless transmitting unit 5 adopts the 2.4G wireless telecommunications chip of super low-power consumption, realizes the transmission of pressure signal and pressure parameter.
As shown in Figure 6,Described pressure sensor unit 2 adopts the device of the pressure transducer of low-voltage, low-power consumption as data acquisition.
The utility model is used for the force value of collection site, when hand-held pressure receiving trap when the pressure acquisition device, power turn-on, by gathering 0 to 100 millivolt voltage signal of pressure sensor unit, convert 0 or 2.5 volt of voltage to, the force value that becomes voltage transitions the user to demarcate sends by wireless transmitting unit 5 then.
As shown in Figure 7 and Figure 8, the 3.6V battery is through the system power supply of U3 power supply unit generation 3.3V, and the system power supply of 3.3V produces 2.5 volts of stable reference voltage voltage supply force sensor units through U4 again and uses.
As shown in Figure 5 and Figure 6,Collecting unit is divided into temperature sensor unit 3 and pressure sensor unit 2 two parts, and the environment temperature by the U5 acquisition system is so that be used for the error that compensatory pressure causes because of environment temperature, thereby improves the measuring accuracy of system.Pressure acquisition carries out delivering to controlled processing unit 1 after the processing and amplifying to signal by U2 by 0 to 100 millivolt of voltage signal that pressure sensor unit U6 produces the corresponding pressure range.
