Embodiment
The radio input device 10 that possesses low-voltage pressure prompting function of the present utility model mainly is will be before battery does not soon have electricity, just force the user will more renew battery immediately, avoid soon not having the battery of electricity as still continuing to provide the words of electric power by this, when the user in a few days no longer uses radio input device in the time of one section, the situation that battery spills electrolytic solution has taken place, and erode to the inside of radio input device, tend to cause the damage of electronic circuit, cause radio input device to re-use.
Fig. 1 shows the configuration diagram of radio input device of the present utility model, and Fig. 2 shows by the performed process flow diagram of the utility model microcontroller.In Fig. 1, the specific embodiment of radio input device 10 can be Wireless Keyboard, wireless mouse, perhaps is even the wireless game rocking bar.Convenient and be easy to understand for the purpose of the reason of the present utility model in order to disclose explanation, Fig. 1 does not give again and draws out other interlock circuit that constitutes radio input device 10, and for example the X-Y displacement of the key-press matrix circuit of Wireless Keyboard, wireless mouse produces circuit.Radio input device 10 mainly includes microcontroller 101 and battery 103, wherein battery 103 is the electric power in order to provisioning wireless input media 10, microcontroller 101 is in order to handle the input signal of radio input device 10, for example be used for handling the button input signal of key-press matrix circuit, or handle the cursor input signal that the X-Y displacement produces circuit.The major technique feature of radio input device 10 of the present utility model is to be: when radio input device 10 in when running, microcontroller 101 is detected the voltage of battery 103 at any time, when the voltage of battery 103 drops to the light current degree, microcontroller 10 can send the low-voltage warning message in order caution unit 105, for example make light emitting diode 105 send the flicker cresset, perhaps microcontroller 101 transmits the low-voltage warning message and gives corresponding wireless receiver, and then, on the screen of computing machine, demonstrate this voltage warning message via the computing machine that connects wireless receiver.When microcontroller 101 voltage of detecting continues to drop to lower voltage limit, when microcontroller 101 detects this situation, though it possesses power capability battery 103 voltages of this moment, still can allow radio input device 10 temporarily keep normal operation, but characteristic of the present utility model is exactly to play a role fully at the moment the time, microcontroller 101 makes radio input device 10 lose all functions fully, for example microcontroller 101 makes Wireless Keyboard can't produce any button input signal, or make wireless mouse can't produce any cursor input signal, after allowing the user experience immediately whereby must more to renew battery, so can continue to use radio input device 10 again.
The person of connecing illustrates the relevance of above-mentioned cell voltage and lower voltage limit with concrete enforcement example.The electrical code of the microcontroller 101 that the utility model adopted, for example for the minimum operating voltage of the normal working voltage of 3.2V (VCC), 2.0V, possess sleep for electricity saving pattern, built-in analog/digital signal converter or the like.Battery 103 in Fig. 1 can be adopted with 3V (volt), also can be in series by two new batteries of 1.5V, changes into the power for operation that 3.2V is used as microcontroller 101 via integrated regulator (IC) 107 again.The positive terminal of battery 103 also is connected to the input pin position of the analog/digital signal converter of microcontroller 101 simultaneously, to offer the voltage that microcontroller 101 is used for detecting battery 103, microcontroller 101 just can grasp the generation of battery 103 decline lower voltage limits whereby.When voltage that microcontroller 101 is detected between 2.2V and 2.1V scope the time, that is be the embodiment of above-mentioned light current degree between the voltage range of 2.2V and 2.1V, the cell voltage of this moment still still greater than lower voltage limit and can radio input device 10 one period long period of operation, in this stage, microcontroller 101 just can make caution unit 105 send the low-voltage warning message.Emphasized that again though radio input device 10 has the situation of low-voltage warning message, battery 103 its tool electric power of present stage still can allow radio input device 10 operate.When the voltage that is detected when microcontroller 101 drops to the lower voltage limit of 2.1V again, voltage soon approaches the minimum operating voltage of microcontroller 101 this moment, this moment, microcontroller 101 just made radio input device 10 lose all functions fully immediately, for example microcontroller 101 makes radio frequency (RF) emission 109 modules cut out its function, can't launch any signal again, or for example microcontroller 101 is advanced into the sleep for electricity saving pattern certainly, and can't handle any button input signal or cursor input signal, after allowing the user experience immediately in view of the above must more to renew battery, so can continue to use radio input device 10 again.
The decision lower voltage limit mode of above-mentioned disclosed microcontroller 101 minimum operating voltage is in order to disclose explanation the utility model, and therefore lower voltage limit deciding means of the present utility model is not limited to.All be familiar with this skill personage should be able to be according to the whole physical circuit of radio input device 10, decide to allow the minimum operating voltage of radio input device 10 operations, and according to and as lower voltage limit.
Moreover, microcontroller 101 can further be used for exporting battery 103 remaining electric weight data, its enforcement means can adopt the wireless receiver that battery dump energy information is sent to radio input device 10 correspondences, and then, on the screen of computing machine, demonstrate this dump energy via the computing machine that connects wireless receiver.
