The principle of the reduction wireless mouse power consumption method that the present invention proposes is to organize the mouse displacement data more, for example N organizes, merge into a single package transmission to the wireless mouse receiver, then by the wireless mouse receiver merged mouse displacement data recovery is become original many groups displacement data again, be divided into by receiver more afterwards and N time data supported in displacement and be sent to computing machine.Thus, because the displacement data amount that single transmits increase, so the number of times that the required data of mouse transmit will reduce the therefore power consumption of having saved mouse.Next be elaborated with embodiment.
Please consult Fig. 3, Fig. 4 (b) and Fig. 4 (c) simultaneously, Fig. 4 (b) transmits the sequential synoptic diagram of displacement data package to wireless signal receiver for the wireless signal transmitter of wireless mouse one preferred embodiment of the present invention; And Fig. 4 (c) is the sequential synoptic diagram of the wireless signal receiver transmission mouse displacement data of wireless mouse one preferred embodiment of the present invention to computer system.When the first mobile wireless of user mouse 200, can produce one first mouse displacement data 2141 (among Fig. 4 (a)), and first control module 202 is converted to the first displacement data package 21 with the first mouse displacement data 2141, and wherein the data layout of the first mouse displacement data 21 and the first displacement data package 21 is identical with mouse displacement data and displacement data package in the known technology.In this preferred embodiment, wireless mouse 200 is defined as the first mouse displacement data 2141 by the mouse displacement data that stationary state is produced when being used state, the first mouse displacement data 2141 directly are not transferred to wireless signal receiver 203 by accumulation, its reason is, in order to keep the sensitivity of wireless mouse 200, therefore this kind then directly is output by the mouse displacement data that stationary state is produced when being used state, and can not make the user feel that the operant response of wireless mouse 200 is slow.Generally speaking, in this preferred embodiment, the first mouse displacement data 2141 directly are transmitted and can merge into same data packet with next mouse displacement data, and after beginning to produce from next mouse displacement data, the package of every single transmission will contain at least two group mouse displacement data.
After the first mouse displacement data 2141 receive by wireless transmission and by wireless signal receiver 203 with the form of the first displacement data package 21, second control module 205 is converted to the first mouse displacement data 2141 originally with the first displacement data package 21, and the first mouse displacement data 2141 are sent to computer system 204.Wireless mouse 200 continues to be operated by the user and continues to produce the second mouse displacement data 2241 and the 3rd mouse displacement data 2242, shown in Fig. 4 (a).In the second mouse displacement data 2241 and the 3rd mouse displacement data 2242, have only mouse horizontal shift data and mouse vertical offset data difference, other value data is identical, be illustrated in these two groups of mouse displacement data, the user has carried out moving of level and vertical direction to wireless mouse 200.
In this preferred embodiment, setting the displacement data that at every turn is transmitted is 2 groups, and when the low-speed mode of wireless mouse 200, it is 16 milliseconds that wireless mouse transfers data to T1 of the employed wireless transmission time interval of receiver, and wireless signal receiver transmit data to the employed wire transmission of computing machine time interval T2 be 8 milliseconds.
First control module 202 is not converted to the data packet form with the second mouse displacement data 2241 when producing the second mouse displacement data 2241, and when the 3rd mouse displacement data 2242 produce, first control module 202 is merged into the single second displacement data package 22 with the second mouse displacement data 2241 and the 3rd mouse displacement data 2242, wherein the second displacement data package 22 comprises the second wireless signal preamble 221, second device identification code 222, second sign 223, the second carrying data 224 and the second cyclic redundancy check code 225, and the second carrying data 224 comprise the second data type sign indicating number DI22, the second button pressing data Key22, the second mouse horizontal shift data X221, the second mouse vertical offset data Y221, the 3rd mouse horizontal shift data X222, the 3rd mouse vertical offset data Y222, the first roller rolling data Z11 and the first window level ticker data H11.Can know that by Fig. 4 (b) the expression second displacement data package 22 comprises the second mouse displacement data 2241 and the 3rd mouse displacement data 2242.And in the back 16 milliseconds time of the transmission first displacement data package 21, utilize wireless signal WS to transmit the second displacement data package 22, and wireless signal receiver 203 is after receiving the second displacement data package 22, second control module 205 disassembles the second displacement data package 22 into the second mouse displacement data 2241 and the 3rd mouse displacement data 2242 originally, with per 8 milliseconds of frequency gradation once the second mouse displacement data 2241 and the 3rd mouse displacement data 2242 is sent to computer system 204 again.
Similarly, please consult Fig. 4 (a) once again, after the 4th mouse displacement data 2341 produce, first control module 202 is not converted into the data packet form, and after the 5th mouse displacement data 2342 produce, first control module 202 is merged into a triple motion data packet 23 with the 4th mouse displacement data 2341 and the 5th mouse displacement data 2342, shown in Fig. 4 (b).When triple motion data packet 23 is transferred into wireless signal receiver 203, second control module 205 is the 4th mouse displacement data 2341 and the 5th mouse displacement data 2342 with triple motion data packet 23 reduction decomposition, and again the 4th mouse displacement data 2341 and the 5th mouse displacement data 2342 being transferred to computer system 204 respectively, mouse displacement data thereafter are by that analogy.
Above embodiment is in the wireless transmission situation of low-speed mode for wireless mouse of the present invention, when if wireless mouse of the present invention is in full speed pattern (Full Speed), the wire transmission time interval can be 1 millisecond, and the displacement data that single package comprised that at every turn is transmitted can reach 10 groups of mouse displacement data.In theory, with situation about can estimate at present, 32 groups of displacement datas can be accumulated as same package at most and transmit again.
Compared to known technology, the wireless transmission in the known technology is mouse displacement data of every generation, just is converted into the package form, and per 8 milliseconds carried out wireless transmission one time, that is to say that wireless mouse just consumes electric power one time for per 8 milliseconds.The present invention will form single package after the many groups of mouse displacement data accumulation of generation, and re-using, the time interval of length will comprise the single package transmission of many group displacement datas to wireless signal receiver.Comprise under the situation of 2 groups of displacement datas at every single package, wireless mouse only needs per 16 milliseconds to carry out a wireless transmission and get final product, this is because the data volume of single transmission is enhanced, so the number of times of needed wireless transmission can be lowered, thereby reduced wireless mouse and transmitted the required electric power that expends of data.
The above only is the preferred embodiments of the present invention, be not in order to limit claim of the present invention, therefore all other do not break away from the equivalence of being finished under the disclosed spirit and changes or modification, all should be contained in the application's claim institute restricted portion.
