In the present embodiment, the configuration of the transmitter / receiver of the wireless mouse, in particular the wireless mouse, and the synchronization process of the transmission / reception period (hereinafter referred to as 'peering') will be described in detail.

1 is a block diagram schematically showing the internal configuration of a transmitter and a receiver of a wireless mouse according to a preferred embodiment of the present invention. As shown in FIG. 1, a receiver 200 of a mouse is installed in a computer, and in general, the receiver and the computer transmit and receive data to each other by using a universal serial bus (USB).

The transmitter 100 of the mouse includes a first control unit 120 for controlling the operation of the transmitter of the mouse, an optical sensor unit 130 for detecting the movement of the mouse, and a wireless signal transmitter 110 for transmitting an operation signal of the mouse to the receiver. It is provided. The optical sensor unit 130 detects the positional movement of the mouse using an optical signal, converts the detected signal into an electrical signal, and transmits the detected signal to the first control unit. The first controller 120 converts the signal transmitted from the optical sensor unit into a preset data format and then transmits the signal to the receiver 200 using the wireless signal transmitter 110.

On the other hand, the receiver 200 of the mouse includes a wireless signal receiving unit 210, a second control unit 220 for controlling the overall operation of the receiver, and an interface unit 230 for transmitting and receiving data with the computer. Here, the interface unit 230 may use a communication protocol such as USB, RS232C. In a preferred embodiment of the present invention, the wireless signal transmitter and receiver 110 and 210 of the transmitter and receiver use a transmitter and a receiver using Zigbee (a wireless protocol of IEEE 802.15.4). Equipment that supports communication may optionally be used.

Hereinafter, a peering process in which the transmitter and the receiver of the wireless mouse having the above-described configuration are synchronized will be described in detail. Prior to describing the peering process, a form of a data packet transmitted and received during a transmission / reception period of a wireless mouse according to a preferred embodiment of the present invention will be described. 2 is a diagram showing the form of a data packet according to a preferred embodiment of the present invention. Referring to FIG. 2, a data packet generally includes a header, a data, and a frame check sequence.

The header part is composed of 1 byte, and the first and second bits indicate a data type, and in case of '00', indicates data and '01' indicates peering data. The third and fourth bits of the header part indicate the type of peering mode, and in case of '00', a connection request signal in case of '01', a connection request confirmation signal in case of '01', and a channel request in case of '10'. If the signal is '11', this indicates a channel assignment confirmation signal.

The data portion is composed of bytes of a predetermined size, and records data transmitted and received during the transmission and reception period of the wireless mouse.

The next frame check unit, which is added to the end of the packet to detect an error of the packet, consists of 2 bytes and includes information such as parity or periodic addition check (CRC) added to detect an error.

Hereinafter, the peering process of the transmission / reception period of the wireless mouse which transmits / receives the data packet will be described based on the form of the above-described data packet.

First, FIG. 3 is a flowchart sequentially illustrating a peering operation in a mouse transmitter according to a preferred embodiment of the present invention. Hereinafter, a peering process of the first controller of the mouse transmitter will be described in detail with reference to FIG. 3.

First, when a battery of a mouse is newly inserted and power is supplied to the mouse, it is checked whether a button of the mouse is input for a predetermined time. If the mouse wheel button or the left / right button is input for a predetermined time or more (step 200), the device enters a peering mode. Otherwise, the mouse transmitter is normally operated. For example, if the wheel button or the left / right button is continuously pressed for 5 seconds or more after power is applied to the transmitter of the mouse, the controller enters the peering mode.

When the mouse transmitter enters the peering mode, the transmitter first transmits a connection request signal for requesting connection of a transmission / reception period to the receiver of the mouse (step 210), and then a connection response signal for allowing a mutual connection from the receiver is received. In step 220, the transmitter analyzes the signal received from the receiver and, in the case of the normal connection response signal, transmits a connection confirmation signal to the receiver indicating that the connection is normally performed (step 230). If the connection response signal is not received from the receiver after step 310 is executed, the process returns to step 310 and repeatedly transmits the connection request signal with the receiver, and waits for the connection response signal from the receiver.

Next, in step 330, the transmitter that transmits the connection confirmation signal to the receiver transmits a channel allocation request signal for requesting allocation of a channel to enable data transmission and reception of a transmission and reception period to the receiver (step 340). When a channel assignment signal including information about the channel is received from the receiver (step 350), a channel assignment confirmation signal indicating that channel allocation is normally performed is transmitted to the receiver (step 360).

Next, the transmitter reads the allocated channel information from the channel assignment signal received by the receiver in step 350 and resets the channel therein according to the read channel information (step 370). Next, the transmitter of the mouse terminates the peering mode, performs data transmission and reception to the receiver using the reset channel and performs normal operation (step 380).

4 is a flowchart sequentially illustrating a peering operation in a mouse receiver according to an exemplary embodiment of the present invention. Hereinafter, a peering process of the second controller of the mouse receiver will be described in detail with reference to FIG. 4.

First, the receiver of the wireless mouse detects the moment of connection to the computer (step 400), and then checks whether a connection request signal for peering operation is received from the mouse transmitter for a predetermined time (step 410). If the reception of the connection request signal from the transmitter in step 410 is confirmed, enter the peering mode. First, the receiver grants a connection with the mouse transmitter (step 430), transmits a connection response signal to the transmitter (step 440), and then receives a connection confirmation signal from the transmitter (step 440). If the connection confirmation signal is not received in step 440, the process returns to step 430 to repeatedly transmit the connection response signal to the transmitter and waits for a signal from the transmitter.

Next, when a channel assignment request signal is received from the transmitter (step 450), after confirming the assignable channel of the receiver (step 460), a channel assignment signal for allocating a specific channel of the receiver is transmitted to the transmitter (step 470). If a channel allocation confirmation signal from the SRS is received (step 480), the peering mode is terminated and a normal operation as a mouse receiver is performed (step 490).

5, the operation of the transmitter and receiver of the wireless mouse according to the preferred embodiment of the present invention will be described as a whole. 5 is a flowchart for sequentially explaining data transmitted and received between a transmitter and a receiver of a wireless mouse.

As shown in FIG. 5, when a peering request signal from a user is detected at the mouse transmitter (step 500), a connection request signal with the receiver is transmitted to the receiver (step 520). On the other hand, the receiver detects that the connection to the USB port of the computer (step 510), and if the connection request signal from the transmitter is confirmed, and transmits a connection response signal that allows the connection between the transmitter and the receiver to the transmitter (step 530). Next, the transmitter transmits a connection confirmation signal with the receiver to the receiver (step 540), and transmits a channel request signal for requesting channel allocation to the receiver (step 550). After receiving the channel request signal, the receiver checks the assignable channel and transmits a channel assignment signal including channel information to the transmitter (step 560). After the transmitter checks the channel assignment signal and transmits the channel assignment confirmation signal to the receiver (step 570), the transmitter performs an operation as a normal mouse transmitter using newly allocated channel information. On the other hand, after receiving the channel assignment confirmation signal from the transmitter, the receiver performs the operation as a normal mouse receiver.

Next, a peering process of a transmission / reception period of a wireless mouse according to another embodiment of the present invention will be described. The wireless mouse according to the present embodiment is changed to the standby mode for peering for a predetermined time when the receiver is connected to the computer and the first power is applied. During the standby mode for peering of the receiver, if a peering request signal from the transmitter is detected, the peering mode is entered. At this time, the transmitter transmits a peering request signal to the receiver when the wheel button is pressed for 5 seconds or longer or the left / right button is pressed for 5 seconds or more. Since the operation process after entering the peering mode is the same as that in the above-described preferred embodiment, redundant description is omitted.

 Next, a peering process of a transmission / reception period of a wireless mouse according to another embodiment of the present invention will be described. The transmitter of the wireless mouse according to the present embodiment automatically sends a peering request signal to the receiver when the battery is removed and reinserted or first inserted. Meanwhile, the mouse receiver enters a peering mode when a peering request signal from a transmitter is transmitted and a button attached to the receiver is pressed for a predetermined time or more. Since the operation process after entering the peering mode of the transmitter and receiver of the mouse is the same as that in the above-described preferred embodiment, redundant description is omitted.

Next, a wireless mouse in which a plurality of transmitters can be connected to one receiver according to another embodiment of the present invention will be described in detail. 6 is a block diagram illustrating an example of a transmitter and receiver of the wireless mouse according to the present embodiment. As shown in FIG. 6, while the first transmitter 610 is connected to one receiver 600 of the wireless mouse, the second transmitter and the nth transmitter may be additionally connected.

The receiver of the wireless mouse according to the present embodiment further includes a separate mode setting button for adding a transmitter, and when the mode setting button is pressed, the receiver enters a peering setting mode. In this case, peering information for the first transmitter preset in the receiver is maintained.

The receiver entering the peering setup mode checks whether a connection request signal is transmitted from an external second transmitter, and if a connection request signal is detected, proceeds with peering with the second transmitter to allocate a new channel to the second transmitter. Done. In this case, since the operation of the receiver that detects the connection request signal is the same as that described in the preferred embodiment, redundant description thereof will be omitted. According to this embodiment, one receiver of the wireless mouse can use a plurality of transmitters.

Meanwhile, the present invention can be applied to a wireless keyboard which is one of the wireless devices, and the synchronization process between the transmitter and the receiver of the wireless keyboard is the same as that of the wireless mouse. However, the controller of the transmitter of the wireless keyboard determines whether there is a peering request according to a predetermined key input, and when a peering request from a user is generated by the input of a specific key, the same as that of the wireless mouse described above. Will work.
