Abstract
An apparatus capable of increasing reliability and a utilization rate of a battery pack is formed by one or more battery packs and a battery pack control unit. The battery pack control unit is formed by an electric quantity statistics unit, an over-current protection unit, a MCUand a power supply output unit. The each battery pack is connected in series with one battery pack control unit. By using the battery pack control unit in the apparatus, the electric quantity statistics is timely performed. When two or more battery packs which are connected in parallel are used, the reliability can be increased and the utilization rate of the battery packs can be increased too.
Description
Affiliated technical field
The present invention relates to oil, colliery and geological prospecting drilling engineering deviational survey field, relate in particular to a kind of device that improves battery pack reliability and utilance.
Background technology
Along with the development of oil, colliery and geological prospecting drilling well, need to be to down-hole equipment attitude Real-Time Monitoring, so that wireless drilling inclinometers is widely used, the attitude parameter that this measuring system needs battery pack to power to finish drilling tool is uploaded in real time.
At present, when carrying out aboveground measurement, use battery pack to power, when the battery electric quantity residue is not enough, just can not guarantee next instructions for use, in order to guarantee normal power supply, the battery pack that need to more renew causes a large amount of battery pack not take full advantage of like this.The degree of depth along with well constantly increases in addition, and is higher to the reliability requirement of battery pack, if electric weight is under-supply in the deep-well measuring process, can cause continuing measuring, and again changes battery, needs drilling team repeatedly to pull out of hole, and can strengthen drilling cost like this.
Summary of the invention
The deficiency that can not take full advantage of in order to overcome existing battery pack, the utility model provides a kind of device that improves battery pack reliability and utilance.
The technical scheme that its technical problem that solves the utility model adopts is: the utility model is comprised of one or more battery pack and battery pack control unit; the battery pack control unit is comprised of electric weight statistic unit, over-current protecting unit, MCU control unit, power supply output unit; it is characterized in that battery pack control unit of each battery pack series connection.
When lower well measurements, can adopt one or more battery pack and battery pack control unit to power according to design, when using the series connection of single battery group and battery pack control unit, in time add up electric weight, and play overcurrent protection; When using two or more battery pack, battery pack control unit of each battery pack series connection can be added up each battery electric quantity, preferentially opens the low battery pack supplying power for outside of electric weight.
The beneficial effects of the utility model are that the utility model utilizes the battery pack control unit in this device, in time adds up electric weight, when using two or more battery pack in parallel, both can improve reliability, can improve again the utilance of battery pack.
Description of drawings:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model single battery group connected mode.
Fig. 2 is a plurality of battery pack connected modes of the utility model.
Fig. 3 is control flow chart of the present utility model.
Embodiment:
In Fig. 1; a kind of device that improves battery pack reliability and utilance of the utility model; be comprised of one or more battery pack and battery pack control unit, the battery pack control unit is comprised of electric weight statistic unit, over-current protecting unit, MCU control unit, power supply output unit.
The electric weight statistic unit is for detection of battery pack output current and statistics battery pack output electric weight.
Over-current protecting unit, for detection of the control of the external output current of battery pack, can automatic disconnection power supply output when excessive when load current occurring, with the protection battery pack.By over-current protecting unit, for the damage that reduces battery, in order to improve the battery pack reliability.
The MCU control unit is controlled battery voltage output according to the behaviour in service of battery electric quantity, and can be communicated with other battery pack control units.The MCU control unit is preferentially opened the low battery pack supplying power for outside of electric weight by each battery electric quantity of statistics, to guarantee the utilance of battery pack.
The power supply output unit is used for realizing battery pack supplying power for outside state: close output and open output.
In Fig. 2, when using two or more battery pack, battery pack control unit of each battery pack series connection, and the mode that is connected in parallel is adopted in power supply output, isolate by diode between every group, as long as there is like this Battery pack power supply just can guarantee supplying power for outside.
In Fig. 3, when a plurality of battery pack are used simultaneously, it is many from pattern to need that the battery pack control unit is arranged to a master, wherein the master battery pack control unit needs the electric weight of other battery pack is read, and to determine the opening minimum battery pack of electric weight, can guarantee that the battery pack that electric weight is low uses first, then automatically switch to the high battery pack of electric weight, can guarantee the abundant use of battery pack, can ensure again in deep-well and use for a long time, to reduce drilling team's trip-out number of times.
Claims (3)
