[0021] The utility model is further described in detail below with reference to the accompanying drawings.

[0022] An autonomous controllable input device suitable for a marine operating console comprises a housing and an internal circuit, wherein the internal circuit is installed inside the housing, such as Figure 1 As shown, the casing includes a ball bearing, an upper shell, a lower shell and a keypad. The lower shell is the base of the input device and is installed on a marine operating table. The upper shell is installed above the lower shell. The ball bearing is installed on the left side of the upper shell to accommodate the thumb of the user. The keypad is installed on the right side of the upper shell to accommodate the index finger and middle finger of the user.

[0023] like Figure 2 As shown, the internal circuit includes a rolling ball system, a main control system and a key system, wherein the rolling ball system and the key system are respectively connected to the main control system, and the main control system is connected to the computer host through a transmission interface. The rolling ball is connected to the rolling ball system, and the key keyboard is connected to the key system.

[0024] When the ball rolls, the sensor of the rolling ball system obtains continuous surface images through optical signals, and performs mathematical operations on the changes in the image to determine the direction and distance of movement, thereby measuring the position change. The sensor of the rolling ball system includes an image acquisition system, a digital signal processor, and a three-wire serial port. The sensor part uses YS8009 from Huichun Technology. YS8009 is a high-performance, low-power CMOS processing optical mouse sensor with an integrated DSP unit. It does not require mechanical movement and has a good effect of drawing lines across the interface. The X, Y two-dimensional coordinates can be accurately controlled through the trackball sensor circuit.

[0025] The main control system includes a main control chip, a power supply circuit and an interface circuit, wherein the power supply circuit and the interface circuit are respectively connected to the main control chip, the power supply circuit is used for power supply, and the interface circuit is used for providing a transmission interface.

[0026] like Figure 6 As shown in the figure, the main control chip uses CH32V103C8T6 single chip microcomputer. The main control system is the core device of the device, which is responsible for handshaking between the device and the host computer, scanning the keys, querying the key values, and sending them to the host computer.

[0027] like Figure 3 As shown, the power supply circuit includes the ME6211 power supply chip and its peripheral circuits, and the interface circuit includes the GSRO5LC chip and its peripheral circuits. ME6211 is a high-precision, low-noise, low-voltage-difference LDO voltage regulator chip that can convert 5V input to 3.3V output.

[0028] like Figure 4 As shown in the figure, the key keyboard includes three keys: left, middle and right. The keys are in the form of IO keys and are pressed by pulling up. Combined with the selection of the control chip and the consideration of the overall mouse system, the keys are scanned to obtain the key positions of the keys. Each key has a unique corresponding value. When the key is pressed, the key is turned on and the main control system collects the key. According to the physical position of each key, the main control system transmits the key value corresponding to the key to the host computer through USB or PS / 2 transmission protocol.

[0029] like Figure 5As shown in the figure, the interface circuit includes the GSRO5LC chip and its peripheral circuits. Because the clock and data signal lines of the PS2 interface have pull-up resistors, and the USB interface only has one of the D+ or D- connected to a pull-up resistor, the microcontroller identifies the interface type by judging the high and low levels of the two IO ports. The GSR05LC ESD electrostatic diode array is used at the interface to protect components from ESD interference.

[0030] The advantages and beneficial effects of the utility model are:

[0031] 1The devices used in this equipment are all 100% independently controllable products, and are standard components with mature status, stable quality, high reliability and sustainable supply.

[0032] 2. Through the interface circuit, the utility model is compatible with both USB and PS2 interfaces and can be adapted to most control consoles.

[0033] 3. High adaptability, can adapt to a variety of host computer operating systems: all series of Windows, Zhongbidi Kylin, Galaxy Kylin, Linux, Unix and other systems.

[0034] 4 The casing material is made of rust-proof aluminum alloy plate (5A06-F GB / T3880-1997) to reduce the weight of the equipment, simplify the process flow, shorten the processing cycle, ensure performance while reducing equipment costs.

[0035] The implementation method of the utility model is:

[0036] The input device is connected to the host through an interface. The main control device continuously scans the left and right buttons to determine whether the button is pressed. When it is found that the button is pressed, the corresponding key value is uploaded to the host computer. The ball movement on the input device will be measured by the sensor sending a continuous surface image to measure the position change. The sensor determines the direction and amplitude of the tracking ball movement through calculation, thereby determining the direction of movement of the tracking ball, and the main control system uploads the data to the host computer.

[0037] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention includes but is not limited to the embodiments described in the specific implementation manner. Any other implementation manners derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
