Therefore, it is to be understood that the following description is a broad disclosure of those skilled in the art and is not intended to limit the invention. The invention can convert various measurement instruments to measure the measured value of the slope of the area to be tested into an optical signal, and represent the logic 1 and the logic 以 with high-intensity LEDs of different colors respectively, and then capture the image by the image 7 200947319 device' For example, the camera captures the image of the high-intensity LED, and provides the remote administrator with the image recognition method to identify the optical signal captured by the image, so as to complete the image monitoring and measurement data communication at the same time. Features. The first diagram is a system architecture diagram of an image data transmission system and method according to an embodiment of the present invention, including a plurality of lighting coding devices 10, an image recognition device 20, and a plurality of conversion devices. Each of the light encoding devices 1 is electrically coupled to the plurality of sensing devices 4 via the corresponding converting device 30 to convert the sensing signals output by the sensing devices 40 and output light having a plurality of changes. a signal, and the image recognition device 20 captures a picture including the light coding device 10, and performs image recognition on the surface to convert the optical signal generated by the light coding device 1 into an output digital signal. . The image recognition device 20 can include a calculation unit (not shown in the figure) and an image capture unit (not shown). The image-removing unit can capture a side surface of the image-encoding device for a camera, a camera or a general image capturing device, and the computing unit can recognize the image by using a conventional image recognition technology. The optical signal of the light-coding device is turned into a round of digital signal, and since the image recognition technology is a well-known technique, the invention will not be described in the image. . The squeegee and the sensing devices 40 are erected on the slope of the area to be tested to detect various numerical changes in the slope of the area to be tested to provide the administrator with the basis for monitoring and preventing sloping ground disasters. Among them, ^, etc. 200947319 Sensing f set 40 includes a ground slide meter to measure the displacement of the slope of the slope. 'Pressure type water level gauge is used to monitor the height and speed of the groundwater level. The rain gauge is used to measure the rainfall on the surface. Or tilt gauges, time domain reflectometers, etc., respectively, to measure the required slope information. Referring to the second figure, a functional block diagram of a light encoding device 1 and a conversion device 30 according to an embodiment of the present invention is shown. Due to the measurement principle and processing circuit of various measuring instruments, the output method is different. At present, the types of output signals of various measuring instruments can be divided into four categories: voltage output, current output, pulse wave output and digital value output. The present invention adopts a binary editing & method to convert the output signals of the sensing devices 40 into a binary encoded form to obtain the largest encoded value with a minimum of high luminance LEDs. Referring to the conversion device 30 of the second figure, a binary input port 31, a voltage input port 32, a current input port 33, a pulse wave input port 34, and a BCD code input port 35 are included. The binary code 'into bee 31 is used to directly transmit the measurement data to the light encoding device 10 when the sensing device 40 outputs the binary encoded measurement data, and the voltage input port 32 is used to When the sensed data in the form of a voltage is sensed, the voltage is converted into a binary coded digital signal via an analog converter (ADC) 38; the pulse input 玮 34 is used to output at the sensing device. When measuring data in the form of current, 'first supply current to a voltage ^ Rs to generate a corresponding voltage' and then transfer the voltage to the analog-to-digital S-bit converter 38' to be converted into a binary coded digital bit 200947319; The pulse input port 34 is configured to convert the pulse wave into a frequency and voltage by a frequency voltage converter (IF/VC) 36 when the sensing device 4 outputs the measurement data in the form of a pulse wave, and then converts the pulse wave. The subsequent voltage is supplied to the analog-to-digital converter 38 for conversion to a 'binary coded digital signal; and the BCD code input '35^ outputs the measurement data in the form of a BCD code at the sensing device 40, directly via a BCD. Code pair binary code converter 37 will BCD Is converted to binary coded digital signal before passing the light coding apparatus 10 codes Pi. Therefore, all of the output signals of the different output types are converted into binary coded digital signals by the conversion device 30, so that the light encoding device 1 can display a single-coded image image. Referring back to the light encoding device 1 in the second figure, each of the light encoding devices 10 includes a light encoding column u and a driving $120. The light coding column u includes a plurality of light-emitting units 111 ′ according to a preset sequence Φ ^ column for providing a plurality of changed optical signals, and the driving unit 12 receives the digital signals provided by the sensing devices 3 a signal, and driving the illumination of the illumination unit Π1 according to the digital signal to generate the optical signal. In an embodiment of the invention, each of the light-emitting units 包含1 includes a red and a blue high-brightness LED for respectively representing a logic 1, and a logic 〇, and the light-emitting units are linearly arranged and formed. A light-coded column consisting of red and blue light. The red light or blue light emitted by the code column and the binary code corresponding to the measured value will display the image pattern of the light code 200947319 column on the image screen. At this time, the red and blue colors are used as the basis for interpretation. , you can know the corresponding measured value. The illuminating unit 111 further determines that the current source is the driving power source, so that the illuminance of the light source generated by each of the illuminating units 111 is the same, so as to increase the accuracy of the image recognizing device 20 during image recognition. In an embodiment of the present invention, the distance between the light-emitting units 111 of the light-coded column 11 can be further adjusted to be close to the photographic distance of the image recognition device 20, so that each light-coded column 11 is The light-emitting unit occupies the same pixel area in the facet captured by the image recognition device 20. After the light-encoding device 10 is set, the pixel position in the face captured by the image recognition device 20 is Therefore, the image recognition device 20 of the present invention performs image recognition only for a specific pixel position in the facet in the manner of the recognition frame, so as to reduce the calculation cost required for the image recognition of the calculation unit. Referring to the third figure, a schematic diagram of adjusting an identification frame according to an embodiment of the present invention is shown. In the kneading surface captured by the image recognition device 20, an identification frame which can adjust the length, width and free movement is set, and the recognition frame is moved to the position where the light coding column image is located, and the identification frame is adjusted. The length and width dimensions are such that the image pattern of each of the light-coded pillars 11 is located in the set identification frame, as shown in the fourth figure. After each set of recognition frames is set, the calculation unit of the image recognition device 20 can directly perform image recognition on each of the recognition frames to convert the optical signals of the respective light code columns 11 into output digital signals. Referring to the 昼11 200947319 surface captured by the image recognition device 20 of the third figure, the long strip formed by the position p〇 is a blank identification frame, and has a shift function, so that the recognition frame can be moved to any position on the fascia. And to change the size of the recognition frame, such as pull-up, pull-down, pull-up, right-pull, etc. The image recognition device 20 is caused to adjust the area covered by the identification frame according to the size of the image pattern of the actual light code column 11. The length of the recognition frame (PI, P2, P3, P4) set in each position will have its fixed coordinate value, which can be used to represent the confirmation number (ID code) corresponding to the instrument, and its optical signal signal The corresponding digital signal is the binary code of each instrument measurement result. After the image recognition device 20 has the function of setting the recognition frame, it is not necessary to perform full-face image recognition, but only for fixed position, fixed-area image data, and color and brightness comparison, and The confirmation of the minimum resolution is determined, so that it is determined that the correct binary code can be quickly obtained and the measurement data of the sensing device 40 corresponding to the ID code is known. In an embodiment of the present invention, the light-coding device 10 ® and the image recognition device 20 can be appropriately adjusted, so that the image patterns of the light-coded columns 11 appear in the peripheral region of the image captured by the image recognition device 20 . In order to avoid affecting the surface condition of the administrator to monitor the slope of the area to be tested.

In the present invention - in the embodiment, the light coding column n: first: ? 111 further may include three kinds of output change light sources, and a ternary optical signal code to provide a change in the large value of the light code 'or decrease under the same value change> light-emitting unit ηι of the light code column 11 Quantity. The figure shows a structure of three kinds of outputs according to an embodiment of the present invention. In this embodiment, the light unit iut contains red, green, and blue light, and has red (R), green (G), or blue light, and dm is 'where red represents 2, and green represents (10)# To convert the binary code into ternary Ξ two: When the LEDs are in the same-value, only the LEDs of the color are illuminated, and the corresponding values can be obtained by combination. The number of the ninth is shown in the sixth figure in the embodiment φ, ,,. The illuminating unit m is made in i: 丄f has three kinds of output hexadecimal codes (38), at this time, there are more illuminating units 111 (28) than the output of 2 13 200947319, so The fewer light-emitting units 111 represent the same value, so that the image recognition device 20 can arrange more light-coded image patterns in the captured surface, so that the same camera can perform more data transfer functions. Reference is made to the seventh block, which is a functional block diagram of a light encoding device 1 and a sensing device 3 of a light-emitting unit 111 having three kinds of output changes according to an embodiment of the present invention.
