The invention relates to a clock hand position detection device which comprises an hour hand dial, a minute hand dial, a mark plate and at least one pair of cameras, wherein the cameras are arranged at one end at which a clock mechanism is connected with an hour hand shaft and uniformly distributed on the circumference of the hour hand shaft; the mark plate is arranged at one end at which the clock mechanism and the hour hand shaft are connected and provided with holes matched with the cameras; the hour hand dial and the minute hand dial are respectively arranged on the hour hand shaft and a minute hand shaft and respectively correspond to the holes on the mark plate; at least more than two areas for indicating clock scales are respectively divided on the hour hand dial and the minute hand dial; and different color sequences are respectively identified in different areas of the same dial. The invention also provides a method for detecting the clock hand positions by utilizing the device. The method comprises the following steps of: shooting the images of the hour hand dial and the minute hand dial at a time by the cameras; converting image information into time values; and outputting the time values to determine the positions of the clock hands. The clock hand detection device and the detection method have the advantages of simple structure, low cost and easy mounting.
Description
technical field [0001] The invention relates to an angle measuring device, in particular to a position detecting device and a detecting method of a large clock hand. Background technique [0002] Judging the accuracy of the position of the clock hand at a certain moment is a convenient and fast method to judge the accuracy of the clock travel time. At present, traditional angle positioning devices include synchros, encoders, etc. Among them, the angle positioning trimming machine is a displacement sensor that uses the principle of self-adjusting step characteristics to change the angle into an AC voltage or from the angle to the angle to measure the angle. An encoder is a measuring element that uses the principle of electromagnetic induction to convert the relative displacement between two planar windings into an electrical signal. It can be divided into two types: linear and rotary. The former is composed of a fixed ruler and a slide rule, and can measure linear displacem...
