Abstract
The invention provides a remote control unit electricity quantity reminding circuit which comprises a voltage detection circuit, an A/D conversion circuit, a controller, an alarm circuit and a starting circuit. The voltage detection circuit, the A/D conversion circuit, the controller and the alarm circuit are connected in sequence, and the voltage detection circuit is connected with the starting circuit. By means of the remote control unit electricity quantity reminding circuit, a user can conveniently detect the electricity quantity of batteries when required, normal usage of the user can be ensured and the electricity quantity can be saved.
Description
Technical field
The present invention is specifically related to a kind of telepilot electricity alert circuit.
Background technology
There is the remote control of various household electrical appliance at present, but remote control all cannot be reminded when battery electric quantity is not enough, such, be easy to the use having influence on user.
Summary of the invention
The object of this invention is to provide a kind of telepilot electricity alert circuit, solve problems of the prior art, whether can being convenient to user, to detect battery electric quantity when needed not enough, guarantees the normal use of user, save power.
The technical solution adopted in the present invention is:
The invention provides a kind of telepilot electricity alert circuit, its special character is: comprise voltage detecting circuit, A/D change-over circuit, controller, warning circuit, start-up circuit, described voltage detecting circuit, A/D change-over circuit, controller, warning circuit connect successively, voltage detecting circuit and start-up circuit.
Switch is provided with between described controller and battery.
The invention has the beneficial effects as follows and can be convenient to user whether detect battery electric quantity when needed not enough, guarantee the normal use of user, save power.
Accompanying drawing explanation
Fig. 1 is connection block diagram of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
The embodiment of the present invention provides a kind of telepilot electricity alert circuit, comprise voltage detecting circuit 1, A/D change-over circuit 2, controller 3, warning circuit 4, start-up circuit 5, described voltage detecting circuit 1, A/D change-over circuit 2, controller 3, warning circuit 4 connect successively, voltage detecting circuit 1 and start-up circuit 5.
Switch is provided with between described controller 2 and battery.
Because A/D change-over circuit 2 needs to consume more electricity, so without the need to gathering voltage data constantly and changing, like this, when needing, by start-up circuit 5 trigger voltage testing circuit 1, the voltage data of collection is after A/D change-over circuit 2 is changed, when determining by controller 3 situation belonging to electricity deficiency, carry out light prompting by warning circuit 4, so that user changes battery in time, guarantee normal use.
Claims (2)
1. a telepilot electricity alert circuit, it is characterized in that: comprise voltage detecting circuit (1), A/D change-over circuit (2), controller (3), warning circuit (4), start-up circuit (5), described voltage detecting circuit (1), A/D change-over circuit (2), controller (3), warning circuit (4) connect successively, voltage detecting circuit (1) and start-up circuit (5).
2. telepilot electricity alert circuit according to claim 1, is characterized in that: be provided with switch between described controller (2) and battery.
