Description
Technical field
The utility model relates to a kind of data collector, relates in particular to a kind of addressable wireless data acquisition device.
Background technology
In the oil recovery production run in field, oil field, need the field data of collection very many, for example, the voltage of pumping-unit motor, electric current, power, power factor, tubing pressure, wellhead temperature, casing pressure, water injection well duty parameter etc.The acquisition technique of these parameters is very ripe, and current many employings scene once table mode gathers.But because the oil production equipment in oil field is numerous, thus how these data are aggregated into administrative authority, and and then form management database, be a workload greatly and have a technology of suitable difficulty.In above-mentioned data acquisition, what at home and abroad generally adopt at present is the mode of hand-kept or data remote.So-called hand-kept, be exactly the keeper of the oil production equipments such as oil pumper or water injection well to field observation or erecting stage measuring instrument, hand filling data form then, this mode is not only backward in technique, and is unfavorable for the computer management of field produces; So-called data remote, is exactly that measurement instrument has comprised telecommunication module, and field data is uploaded to administrative center mechanism by telecommunication network.Although this mode is very advanced, because cost is high and remote network resource restriction, make the popularization of this mode be subject to restriction.
Summary of the invention
The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of addressable wireless data acquisition device.
A kind of addressable wireless data acquisition device of the present utility model, by CPU (central processing unit), DTU (Data Transfer unit), collection starter gear, generating device of the address and wireless data sending device, formed, described CPU (central processing unit) is connected with generating device of the address, DTU (Data Transfer unit) and wireless data sending device circuit respectively, and communication is connected with generating device of the address with CPU (central processing unit) respectively to gather starter gear.
As further improvement of the utility model, in described CPU (central processing unit), establish monostable circuit and drive coil.
As further improvement of the utility model, in described DTU (Data Transfer unit), establish serial 24BIT high-precision A/D chip.
As further improvement of the utility model, in described collection starter gear, be provided with ear magnetosensitive detecting element suddenly.

Embodiment
As shown in Figure 1, a kind of addressable wireless data acquisition device of the present utility model, by CPU (central processing unit) 1, DTU (Data Transfer unit) 2, collection starter gear 3, generating device of the address 4 and wireless data sending device 5, formed, described CPU (central processing unit) 1 is connected with generating device of the address 4, DTU (Data Transfer unit) 2 and wireless data sending device 5 circuit respectively, and 4 communications are connected with generating device of the address with CPU (central processing unit) 1 respectively to gather starter gear 3.In described CPU (central processing unit) 1, establish monostable circuit and drive coil.
When device take over party presses data acquisition key, its central interior processing unit 1 sends magnetic field starting impulse to gathering starter gear 3, through its inner monostable circuit, form the driving pulse of fixed width, drive coil production burst magnetic field, data acquisition side namely gathers starter gear 3, and the Hall magnetosensitive detecting element 6 that gathers starter gear 3 detects magnetic field output afterwards and gathers starting impulse.First this pulse is controlled CPU (central processing unit) and is sent address signal, after verification succeeds, restarts DTU (Data Transfer unit) and carries out analog quantity conversion, and the data superposition address information of generation forms blended data, via wireless data sending device, sends.Because blended data has comprised address information, so can realize addressing formula data transmission.
Wireless data sending device wherein adopts micro power consumption wireless module, and its transmitter current is not higher than 10 milliamperes, and received current is not higher than 5 milliamperes, and effective communication distance is between 0.5～2 meter.
As shown in Figure 2, DTU (Data Transfer unit) 2 receives simulating signal, and simulating signal is converted to digital signal, exports to CPU (central processing unit) 1, also needs to receive the control data of CPU (central processing unit) 1 simultaneously, in order to log-on data conversion equipment 2.The acp chip of DTU (Data Transfer unit) 2 has adopted serial 24BIT high-precision A/D chip AD7705, makes DTU (Data Transfer unit) 2 under the control of CPU (central processing unit) 1, complete the analog to digital conversion of 24BIT.
As shown in Figure 3, in collection starter gear 3, be provided with ear magnetosensitive detecting element 6 suddenly, ear magnetosensitive detecting element 6 receives drive coil in CPU (central processing unit) 1 and produces low-intensity magnetic field signal suddenly, and to CPU (central processing unit) 1, export starting impulse by time-base integrated circuit NE555, then by CPU (central processing unit) 1, control DTU (Data Transfer unit) 2 and carry out data-switching.
As shown in Figure 4, generating device of the address 4 gathers for receiving the starting impulse that starter gear 3 sends, and by 64BIT coding chip EM4101TKC, realizes the unique address coding of image data, and is transferred to wireless data sending device 5.
