The material-sealing equipment is bound to increase the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Wireless, with multiple Wei keys or single keys, and so on, the power consumption is also different. The characteristic is that when the optical mouse is used, the internal (10) light source will not be thief due to the user's temporary It is a power supply that consumes power supply equipment, which is undoubtedly a waste of power supply itself. [Objectives of the Invention] With the rapid changes in various types of information every day and the increasing development of computer technology, modern people have a laptop computer that is commonplace, but the problem of power supply for notebook computers is a problem. Peripheral devices are bound to increase the user's power consumption. In order to cope with the above problems, the present invention utilizes a data access unit in an optical sensor to transmit a value, and the central processing unit is responsible for determining the state of use of the mouse represented by the transmitted value. 200813703 Therefore, the purpose of the present invention is to reduce the power consumption of the pc itself through the power saving technology inside the mouse. The purpose of this month is due to the over-exploitation of global energy sources, resulting in an ever-increasing shortage of available resources. The purpose of the present invention is to extend the use time of the notebook computer through the power saving technology inside the mouse. SUMMARY OF THE INVENTION The above objective, the optical mouse power saving method provided by the present invention comprises the following steps: ' (1) writing a program in the controller, after the mouse action, the micro control The device will automatically detect the value of the sensitivity of the desktop in the light sensor; (2) When the mouse is placed on a certain desktop, the light converges through the circular lens to the light sensor, as long as the mouse moves 'light' The value of the register in the detector will change; (3) The register will pass the detected value to the microcontroller, and the microcontroller will compare the transmitted value with its own value. (4) The comparison obtains that the transmitted value is less than or equal to the preset value, determines that the mouse has been lifted, and the microcontroller automatically reduces the intensity of the LED light source to the minimum power consumption; (5) If the comparison is that the transmitted value is greater than the preset value, the slip is judged to be slippery. The mouse is not lifted and the microcontroller continues to let the mouse work properly. [Embodiment] Referring to FIG. 1 and FIG. 2, we can write a program written in the microcontroller 112. After the mouse 6 8 200813703 is actuated, the microcontroller 112 can directly and automatically lie back and lift the optical sensing. The value of the sensitivity of the desktop 2 to the desktop 2, and compares this value with the value set in its own program, thereby reducing the intensity of the light source 4 to the minimum power consumption. Let's take avago's optical sensor u as an example. A zero optical sensor core -111 can be used to measure the value of the displacement characteristic that the optical sensor u can face. When the mouse is placed on a certain tabletop 2, the light source 4 is concentrated by the circular lens to the optical sensor u, because even a small displacement can cause a change in the interior of the storage port 111, as long as the mouse moves, The value of her 11 will change. The value of u is 255. If the mouse leaves the table 2, the light source 4 cannot be concentrated to the optical sensor u, and the value of the register (1) is 〇. The focus point is important for register 111, which can affect the value of register (1). After the mouse is lifted, the register m of the optical sensor 11 is transmitted to the microcontroller 112 for a value, and the microcontroller 112 compares this value with the value set in its own program, and compares the result as a judgment of the mouse. The basis for leaving the desktop 2. If the value of the register and 11H is less than or equal to the value set by the microcontroller (1) from the light mode, the micro-control 112 will judge that the mouse has been lifted, thus automatically reducing the intensity of the light source 4 to the minimum power consumption. Please refer to FIG. 3, the specific process is: first, the mouse generates a certain displacement; secondly, the register of the optical sensor 11 obtains the value generated by the displacement (assumed to be X); then, the register U1 detects The value X is passed to the microcontroller 112; then, the microcontroller 112 compares the value of the value with its own value (assumed to be 10); finally, if the comparison yields χ less than or equal to 1〇, it is determined that the mouse has been When raised, the microcontroller 112 automatically reduces the intensity of the light source 4 to the minimum power consumption. If the comparison is greater than 10, it is judged that the mouse has not been lifted and is working normally.
