Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
The non-maintaining Wireless loading displacement integrated sensor of a kind of one as shown in Figure 1; for the sensor of a kind of load-carrying and displacement of testing beam-pumping unit sucker rod load and oil pumper stroke; comprise power unit, signal processing and sensor cluster; the Switching Power Supply that described power unit comprises solar energy equipment, the mu balanced circuit be connected with solar energy equipment and is connected with mu balanced circuit; described power unit also comprises the protection circuit be connected with mu balanced circuit, the farad capacitor be connected with protection circuit.In this circuit arrangement, most important two key points: select Acclimation temperature scope is wide, leakage current is little super capacitor and select the Switching Power Supply that Micro Energy Lose, conversion efficiency are high.Because farad capacitor has quick charge, voltage declines along with electric discharge, output circuit relative complex.
Described signal processing comprises signal processing circuit, pressure conditioning Acquisition Circuit and the wireless communication line that super low power consuming single chip processor forms, sensor cluster comprises acceleration and low-power consumption pressure sensor, LOAD CELLS and displacement transducer are integrated together by it, use low-power scm technology, and wireless communication technique, the load signal collected and displacement signal are matched, thus obtain pumping machine merit figure, the duty of reaction oil pumper, as the reference of adjustment oil pumper operating frequency, reach energy-saving and cost-reducing object.
The power-supply system utilizing heliotechnics and super capacitor to form, reaches green, non-maintaining, cost-saving object.
According to the structure of pumping unit horsehead, special pressure sensing and solar panels design frame for movement, easy for installation, do not need to change site machinery structure.
Wherein, described wireless communication line is connected with antenna.
Sensor of the present invention needs to be arranged on the polished rod eye 10 of sucker rod 7 in use, the all pressure of sucker rod 7 all acts on pressure sensor, utilize the change of A/D module acquires pressure, the size of pressure is calculated again by signal processing module, moving up and down along with wire rope on the other hand, the acceleration of pumping rod is measured by acceleration transducer, quadratic integral is carried out to acceleration, again according to the reciprocating feature of sucker rod, draw the fringe conditions that each lamination is divided, so just calculate the displacement of sucker rod, degree of will speed up sensor and pressure sensor are integrated together, use low-power scm technology and wireless communication technology, the load signal collected and displacement signal are matched, thus obtain the duty of sucker rod, as the reference of oil pumper operating frequency, thus reach energy-saving and cost-reducing object.
Mainly with non-maintaining power circuit I, treatment circuit part ii, Sensor section III that solar energy and farad capacitor form.Low power consumption switch power supply respectively with signal processing circuit, nurse one's health Acquisition Circuit, sensor circuit and wireless communication line and be connected, be its power supply.Patent utilization solar energy of the present invention adds a farad capacitance group and becomes power-supply system, because farad capacitor has of a specified duration, environment-adapting ability in application life strong, high charge-discharge efficiencies, high-energy-density feature, can realize in the wild non-maintainingly powering to wireless sensing system; According to the frame for movement of oil pumper, custom-designed shape of a hoof pressure sensor structure, easy for installation, without the need to changing existing field structure; Load and displacement data are sent to neighbouring RTU device by the mode of wireless transmission simultaneously.Achieve: easy for installation, environmental protection, non-maintaining saving human cost, wireless transmission etc.
The design of whole Circuits System all adopts low power dissipation design, and when system works, this electric current is less than 15mA, and when wireless module does not work, electric current is 3mA, and whole system is in low-power consumption duty, and electric current is uA level.
Because merit figure only needs send a secondary data maximum half an hour, half an hour, consumed power operational was as follows:
Half an hour power consumption:
Gather 40s, send 1s, 3mA*40s+15mA*1s=135mAS;
When system is in Micro Energy Lose duty, power consumption is: 30*60*1uA=1.8mAS
Half an hour, power consumption was altogether: 1.8mAS+135mAs=137mAS
The power consumption of every day is: 48*137mAs/3600=1.8mAH
Super capacitor correlation computations:
Capacity F=coulomb (C)/voltage (V)
Transfer capacity, voltage to equivalent electric quantity
Electricity=voltage (V) the x quantity of electric charge (C)
Practical Calculation:
The electricity of voltage 6V 1F (1 farad capacitor) is 6C (coulomb)
Lower voltage limit is 4V, and the effective voltage difference of capacitor discharge is 6-4=2V, so effective electricity is 2C.
2C=2A*S (ampere-second)=2000mAS (milliampere-second)=0.555Ah (MAH)
The 200F electric capacity of voltage 6V, effective electricity is:
0.555mAh*500＝111mAh。
Be that 1.8mAh calculates by the power consumption of every day, 111mAh/1.8mAh=62 days, selects the super capacitor that leakage current is little, and internal loss, about 1%, just calculates by 10%, also can work 50 days.Also just say after super capacitor is full of electricity, can continuous operation 50 days.Feature due to this life of super capacitor can ensure to complete charging rapidly, so add that solar panels cell panel charges, meets power demands completely.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
