Abstract
The utility model provides a storage-battery low-voltage detection and alarm device which includes a one-chip microcomputer connected with an interface of a storage battery, an adjustable resistor, a diode, a display and a buzzer. The device is characterized in that the adjustable resistor and the diode are both connected with an input end of the one-chip microcomputer; and the display and the buzzer are connected with an output end of the one-chip microcomputer respectively. Through voltage change of the storage battery, the constant voltage of the diode is measured in reverse and the voltage of the storage battery is deduced through calculation of the one-chip microcomputer. When the voltage of the storage battery is lower than a set threshold, the one-chip microcomputer controls the display and the buzzer to send out an audible and visual alarm prompt and at the same time, measurement values can be adjusted precisely through the adjustable resistor. The storage-battery low-voltage detection and alarm device has the advantages of being simple in structure, wide in element selectable range, flexible in design, low in cost and high in precision and the like.

Technical field
The utility model relates to a kind of detection alarm device, and especially a kind of accumulator low-voltage detection alarm device, belongs to battery detecting technical field.
Background technology
current various machine room and uninterrupted power source UPS are being used a large amount of accumulators, therefore need to monitor battery tension, when voltage lower than limit threshold values time, need timely reminding user, otherwise can have a strong impact on because of overdischarge the serviceable life of battery.Existing accumulator low-voltage detects, all directly to measure based on accurate reference source, therefore need to configure an accurate reference source chip powers to single-chip microcomputer, the voltage that utilizes self voltage changes accumulator accurately by single-chip microcomputer is measured, but use accurate reference source chip can improve the cost of hardware circuit, cause product cost performance when producing in enormous quantities to reduce, also dwindled the selectable scope of electronic devices and components, the limitation while having increased system simultaneously.Therefore, be necessary prior art to be improved.
Summary of the invention
For overcoming prior art, need to configure accurate reference source chip, and the deficiency such as the cost bringing is high, electronic component range of choice is limited, the utility model provides a kind of accumulator low-voltage detection alarm device.
The utility model provides a kind of like this accumulator low-voltage detection alarm device, comprise the single-chip microcomputer being connected with accumulator interface, adjustable resistance, diode, display, hummer, it is characterized in that adjustable resistance and diode are all connected with the input end of single-chip microcomputer, display is connected with the output terminal of single-chip microcomputer respectively with hummer, so that the unsettled voltage with accumulator, the terminal voltage that measuring diode is stable, by the calculating reverse push of single-chip microcomputer, derive again the voltage of accumulator, when battery tension is when setting threshold values, by Single-chip Controlling display and hummer, send sound, light alarm prompt.
The positive pole of described diode is connected with the input end of single-chip microcomputer, minus earth.
One end of described adjustable resistance is connected with the input end of single-chip microcomputer, and the other end is connected with accumulator interface.
Described display input end is connected with the output terminal of single-chip microcomputer, and display is also connected with accumulator interface.
Described single-chip microcomputer is the conventional products with a plurality of modulus AD translation interfaces.
The utlity model has following advantages and effect: by the change in voltage of accumulator, the constant voltage of measuring diode conversely, by the calculating of single-chip microcomputer, derive again the voltage of accumulator, when battery tension is when setting threshold values, by Single-chip Controlling display and hummer, send sound, light alarm prompt, pass through adjustable resistance simultaneously, can fine adjustment measured value.Have simple in structurely, the optional scope of components and parts is wide, flexible design, and cost is low, precision advantages of higher.
Accompanying drawing explanation
Fig. 1 is the utility model circuit structure diagram.
Embodiment
below in conjunction with accompanying drawing, the utility model is described further.
As Fig. 1, the accumulator low-voltage detection alarm device that the utility model provides, comprise the single-chip microcomputer 4, adjustable resistance 1, diode 2, display 5, the hummer 6 that are connected with accumulator interface 3, wherein adjustable resistance 1 and diode 2 are all connected with the input end of single-chip microcomputer 4, display 5 is connected with the output terminal of single-chip microcomputer 4 respectively with hummer 6, specifically: the positive pole of diode 2 is connected with the input end of single-chip microcomputer 4, minus earth; The lower end of adjustable resistance 1 is connected with the input end of single-chip microcomputer 4, and upper end is connected with accumulator interface 3; The input end of display 5 is connected with the output terminal of single-chip microcomputer 4, and display 5 is liquid crystal display, and display 5 is also connected with accumulator interface 3; Single-chip microcomputer 1 is that all the other elements are commercial product with the conventional products of a plurality of modulus AD translation interfaces.
During work, battery tension is after proportion divider, to single-chip microcomputer 4 power supplies, modulus AD by single-chip microcomputer 4 changes, with single-chip microcomputer 4, self follow the synchronous voltage changing of accumulator the constant voltage of diode 2 is carried out to AD sampling, when the magnitude of voltage that records diode 2 is when setting threshold values, just can judge that battery tension is too low, thereby by single-chip microcomputer 4 driving displays 5 and hummer 6, provide sound, the light alarm prompt of low-voltage, inching adjustable resistance 1, can adjust the degree of accuracy of low pressure alarming threshold values.
