Summary of the invention
The object of the present invention is to provide a kind of method of supplying power to and set-top box phone of set-top box phone, be intended to solve the set-top box phone in the situation that have a power failure, the out of use problem of phone.
The present invention is achieved in that a kind of method of supplying power to of set-top box phone, in described set-top box phone, rechargeable battery is installed, and described method of supplying power to comprises the following steps:
When the electric weight of the rechargeable battery in external power source access and set-top box phone are arranged does not arrive set amount, external power source charges to the rechargeable battery that is connected in described power management chip by the power management chip in the communication module of set-top box phone, and external power source while dispenser device top box phone;
When the electric weight of the rechargeable battery in external power source access and set-top box phone are arranged reaches set amount, external power source dispenser device top box phone;
When outage occured external power source, the rechargeable battery dialogue machine that is connected with described power management chip was powered.
Further, described external power source specifically comprises the step that the rechargeable battery that is connected in described power management chip charges by the power management chip in the communication module of set-top box phone:
First by the current-limiting circuit of communication module inside, rechargeable battery is carried out current-limiting charge, then carry out constant current charge, enable at last constant voltage charge.
Further, described external power source is civil power or portable power source.
Further, described set amount is total capacity over half of rechargeable battery.
Another object of the present invention is to provide a kind of set-top box phone, in described set-top box phone, rechargeable battery is installed, described rechargeable battery is connected in the power management chip in the communication module of set-top box phone, when the electric weight of the rechargeable battery in external power source access and set-top box phone are arranged does not arrive set amount, external power source charges to rechargeable battery, and external power source while dispenser device top box phone; When the electric weight of the rechargeable battery in external power source access and set-top box phone are arranged reaches set amount, external power source dispenser device top box phone; When outage occured external power source, the battery dialogue machine that is connected with described power management chip was powered.
Further, described external power source is civil power or portable power source.
Further, described set amount is total capacity over half of rechargeable battery.
In the present invention, by place rechargeable battery in the set-top box phone, when the access external power supply, rechargeable battery is charged, and when disconnecting external power supply, rechargeable battery just can be powered to the set-top box phone, thereby the phone that guarantees the resident still can use under power-off condition.
Description of drawings
Fig. 1 is the flow chart of the method for supplying power to of the set-top box phone that provides of the embodiment of the present invention;
Fig. 2 is the structured flowchart of the set-top box phone that provides of the embodiment of the present invention.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, is not intended to limit the present invention.
Fig. 1 shows the flow process of the method for supplying power to of the set-top box phone that the embodiment of the present invention provides, and details are as follows:
In step S101, in the set-top box phone, rechargeable battery is installed.
In step S102, detect whether the external power source access is arranged.When the external power source access being detected, execution in step S103; When the external power source access not detected, execution in step S106.
In step S103, whether the electric weight that detects rechargeable battery reaches set amount.When reaching set amount, execution in step S104, when not reaching set amount, execution in step S105.As embodiments of the invention, described set amount is total capacity over half of rechargeable battery.
In step S104, external power source dispenser device top box phone.
In step S105, external power source charges to the battery that is connected in described power management chip by the power management chip in the communication module of set-top box phone, and external power source while dispenser device top box phone.
The process that rechargeable battery is charged can be divided into three phases: first by the current-limiting circuit of communication module inside, rechargeable battery is carried out current-limiting charge, then carry out constant current charge, enable at last constant voltage charge.Can be like this during specific implementation: the judgement battery electric quantity, and determine current charged state according to the battery performance characteristics.If current cell voltage lower than 3.3 volts, charges for the charging current that is no more than 80mA to battery by the inner current-limiting circuit of communication module.In case when cell voltage meets or exceeds 3.3 volts, change 0.3C~0.5C electric current into and carry out constant current charge.When cell voltage reaches 4.05 volts, enable constant voltage charge, guaranteed that battery really was full of in lasting about 30 minutes.
In step S106, the battery dialogue machine that is connected with power management chip is powered.In an embodiment of the present invention, this external power source is civil power or portable power source.
