    摘要: A position detection error correcting method that corrects position detection errors using a limited storage capacity, by calculating position detection error correction values by four simple arithmetic operations at startup to reduce a startup time delay and consumption of a storage capacity even when a portion containing steep error variations exists. Detection error correction values of a position detector are expressed by a correction function using a periodic function, and correction parameters of the correction values are stored in advance in a non-volatile memory. At startup, these correction parameters are read out, and a position detection error correction value corresponding to each detected position is calculated and stored in a random access memory. The output position detection error correction value detector corresponding to each detected position is read out from the random access memory and a corrected detected position value corrected for the detected position value error is calculated.

    摘要: A backlash compensation device for use with a numerically controlled system compensates for a position command signal used to drive and control an object to be controlled. The device includes a reversal detecting unit for detecting a reversal of a direction of driving the object to be controlled based on a reversal of an upward or downward trend in the level of an applied position command signal. A maximum backlash signal generating unit generates a maximum backlash signal corresponding to a maximum value of backlash error every time a reversal of a direction of driving the object is detected. A filter then reduces the level of the maximum backlash signal according to how much time has elapsed since the detected reversal of the driving direction. An adder adds the reduced maximum backlash signal from the filter to the position command signal.

    摘要: When material transport was automated on a building construction site, in a conventional travel tape guide system, it was necessary to replace the tape when it became soiled or when changes were made to a travel route. As a result, the usage efficiency of a material transport vehicle could not be improved on the site due to the fact that changes are made to work floors as demanded by construction schedules. According to this invention, there is provided a sign which is easy to move and which is installed at a turning point or an unloading point on a work floor transport route. An image of the sign is obtained by an imaging device on an autonomous guided vehicle and operating instructions are recognized by image processing. This makes it possible to automate the setting of routes and the control of the vehicle.
