Description
Technical field
The utility model relates to the circuit of the carried charge indication of a kind of circuit of astronomical telescope, particularly a kind of astronomical telescope.
Background technology
Traditional astronomical telescope, what have does not have an electric quantity indication function, and the user in use just can't learn the powering quantity information of product, can not in time charge to product, thus the problem that will occur cutting off the power supply in the use; Though the product that has is provided with electric quantity indication function, all to enters into and to see that just it is very inconvenient to operate after actions menu is progressively searched.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of circuit of checking the carried charge indication of the astronomical telescope that electric weight is directly perceived, quick, easy to operate.
The technical scheme that the invention for solving the technical problem adopted is: a kind of circuit of carried charge indication of astronomical telescope comprises:
One power switcher is used for switching between external power supply and battery;
One general supply controller is used to control cutting out and opening of entire circuit power supply;
One charging control circuit is used for the control signal that battery is provided charging or cuts off;
One electric weight indicating control is used to control cutting out or opening of electric weight indicating circuit;
One voltage reference circuit is used to voltage comparator circuit that a reference voltage is provided;
One voltage comparator circuit is used for that the reference voltage that voltage reference circuit is imported is carried out voltage ratio and indicates control circuit than back and output voltage information to voltage.
Described voltage indicating control is provided with the electric weight pilot lamp.
The beneficial effects of the utility model are: owing to be provided with a voltage reference circuit, be used to voltage comparator circuit that a reference voltage is provided; One voltage comparator circuit, be used for that the reference voltage that voltage reference circuit is imported is carried out voltage ratio and indicate control circuit to voltage than back and output voltage information, described voltage indicating control is provided with the electric weight pilot lamp, so product in use, when the delivery of product was sufficient, the green light on the voltage indicating control can be bright; Cross when low when the delivery of product, the red light on the voltage indicating control can be bright; When the delivery of product was moderate, red light on the voltage indicating control and green light all can be bright, thereby are shown as gold-tinted, and the user just can learn the information about power of product from the color intuitive and convenient of lamp like this, has also avoided sudden power situation in the use.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a circuit block diagram of the present utility model.
Embodiment
With reference to Fig. 1, the circuit of the carried charge of a kind of astronomical telescope of the utility model indication comprises:
One power switcher 1 is used for switching between external power supply and battery;
One general supply controller 2 is used to control cutting out and opening of entire circuit power supply;
