Description
Technical field
The present invention relates to the electricity residual value Application way of wireless device battery.
Background technology
Along with the development of science and technology, mobile terminal device and small-size wireless terminal equipment more and more appear at our life and work with in study, these equipment many employings powered battery, the height of battery utilance is directly connected to the time of wireless device steady operation, in battery management, if reasonably do not arrange rational threshold voltage and relevant electricity residual value utilizes technology, then wireless device will shut down suddenly when arriving certain battery threshold values and quit work, electricity residual value in battery continues to use owing to not having corresponding measure, cause battery availability factor not high, the time that equipment normally works does not arrive perfect condition yet, and due to unexpected power-off shutdown, equipment can be damaged greatly, and the data in equipment can not be preserved in time.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, there is provided a kind of when battery electric quantity is not enough, the proper communication of wireless device can be ensured, the battery utilance of effective raising equipment, extend the electricity residual value Application way of the wireless device battery of battery.
The object of the invention is to be achieved through the following technical solutions: the electricity residual value Application way of wireless device battery, the voltage at the main control chip regular check battery two ends of terminal equipment, according to the supplied character of battery, two threshold voltages U1, U2 are set, battery electric quantity residual value can be utilized, and it comprises the following steps:
S1: main control chip detects the magnitude of voltage at battery two ends;
S2: if the voltage at battery two ends is not less than low valve valve U1, then continue the magnitude of voltage detecting battery two ends;
S3: if the voltage at battery two ends is lower than low valve valve U1 but higher than crossing low valve valve U2, then main control chip changes the operating state of terminal equipment, namely the gain of receiving branch is increased by increasing power consumption, or increase the transmitting power of transmitting branch, continue the electricity residual value in consuming cells, realize the proper communication of terminal equipment;
S4: if the voltage at battery two ends is lower than crossing low valve valve U2, then main control chip control terminal preserves data, quits work, then closes powered battery.
The invention has the beneficial effects as follows:
(1) the present invention when battery electric quantity is not enough, can increase the gain of the receiving branch of wireless module, ensures that the signal of receiving branch can not diminish, improves the accuracy of Received signal strength, extend the time of terminal equipment normal receive data;
(2) the present invention when battery electric quantity is not enough, can increase the power of the external transmitting of wireless module, ensures to transmit and can not weaken, improves the accuracy of transmitting data, extend the time of terminal equipment normal transmission data;
(3) the present invention can when battery exhausts substantially, equipment of initiatively closing a terminal, and stops communication; both protect terminal equipment, ensured the safety of data, take full advantage of again the electricity residual value in battery simultaneously; extend terminal equipment normal working hours, energy savings, extend battery.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is battery discharge characteristic figure;
Fig. 3 is threshold voltage figure.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail: as shown in Figure 1, the electricity residual value Application way of wireless device battery, the voltage at the main control chip regular check battery two ends of terminal equipment, according to the supplied character of battery, two threshold voltages U1, U2 are set, battery electric quantity residual value can be utilized, and it comprises the following steps:
S1: main control chip detects the magnitude of voltage at battery two ends;
S2: if the voltage at battery two ends is not less than low valve valve U1, then continue the magnitude of voltage detecting battery two ends;
S3: if the voltage at battery two ends is lower than low valve valve U1 but higher than crossing low valve valve U2, then main control chip changes the operating state of terminal equipment, namely the gain of receiving branch is increased by increasing power consumption, or increase the transmitting power of transmitting branch, continue the electricity residual value in consuming cells, realize the proper communication of terminal equipment;
S4: if the voltage at battery two ends is lower than crossing low valve valve U2, then main control chip control terminal preserves data, quits work, then closes powered battery.
Its operation principle is as follows: the flash-over characteristic being illustrated in figure 2 battery, as seen from the figure, upon discharging within the regular hour, the voltage at battery two ends can remain unchanged, battery is with constant voltage for power terminal equipment, and when reaching the regular hour while power is being supplied, voltage starts to decline.In figure, dotted line is discharge characteristic curve when being 50mA to the discharging current of load, and solid line is be 70mA discharge characteristic curve to the discharging current of load.As shown in Figure 3, arranging electricity low valve valve is U1, now, cell voltage is low, electricity shortage, terminal equipment occurs that Received signal strength weakens, degradation situation under transmitting power, arranging electricity, to cross low valve valve be U2, now, electricity in battery has been depleted to ultimate attainment, and battery cannot ensure the normal work of equipment.When voltage battery two ends being detected is U1, change terminal equipment operating state, by increasing the gain of receiving branch, increase the measures such as the transmitting power of transmitting branch, battery is followed block curve and is powered to equipment, ensures the normal of communication, continues the electricity residual value in consuming cells simultaneously.When voltage battery two ends being detected is U2, make terminal equipment preserve data, quit work, then powered-down is powered.
If do not arrange threshold voltage, or be only provided with voltage valve U1, when voltage is reduced to U1, terminal equipment can not continue normal work, equipment only arrives t1 normal working hours, the electricity residual value of battery also can not get effective utilization simultaneously, take this battery management technique, terminal equipment can extend to t2 normal working hours, add the time period of t1 to t2, simultaneously when maintaining terminal equipment and normally working, cell discharge voltage is also reduced to 2.8V from 3V, make use of battery electric quantity residual value fully, save the energy, extend the effective time of wireless device.
