Patent number: 10348833Abstract: Provided are a multiplex communication system and a work machine that can appropriately perform transmission and reception of data between a processing circuit used in an industrial network and a multiplex processing section that multiplexes and transmits control data transmitted in the industrial network. A slave processes control data in the industrial network. The control data processed by the slave is transmitted and received by the multiplex communication by a multiplex processing section. A DUMMY-PHY, which is connected between the multiplex processing section and the slave, generates, in a pseudo manner, a signal compliant with an MII communication standard using a pseudo signal generation section, and transmits the generated signal to the slave, thereby performing establishment of communication. The DUMMY-PHY performs data transmission between the multiplex processing section and the slave after establishing communication with the slave.Type: GrantFiled: March 6, 2015Date of Patent: July 9, 2019Assignee: FUJI CORPORATIONInventors: Hidekazu Kanai, Shigemoto Hirota, Nobuo Nagasaka

Patent number: 10205554Abstract: In an electronic component mounting device, a first multiplexing device of a head section which is attachable to and detachable from a Y-axis slider is connected to a second multiplexing device through an electric communication cable. The first multiplexing device, from which the cable is likely to be removed, is connected through the electric communication cable for which the communication failure due to dust or the like is relatively unlikely to occur. Second and third multiplexing devices, from which cables are less likely to be removed, are connected through the optical communication cable. The second multiplexing device separates data directed to the input and output device, among frame data received from the third multiplexing device, multiplexes only data directed to the first multiplexing device from the second multiplexing device, and transfers the multiplexed data to the first multiplexing device by the electric communication cable.Type: GrantFiled: December 3, 2014Date of Patent: February 12, 2019Assignee: FUJI CORPORATIONInventors: Hidekazu Kanai, Nobuo Nagasaka, Shigemoto Hirota

Patent number: 9916752Abstract: A multiplexing communication system is capable of maintaining an appropriate response speed of a control with respect to an electromagnetic motor based on an encoder signal during multiplexing and transmission of the encoder signal. A transmission data composition processing section of a multiplex communication device multiplexes encoder signals ENCD1 to ENCD8 output from a linear scale and a rotary encoder into frame data FRMD and transmits the data. The transmission data composition processing section sets the encoder signals ENCD1 to ENCD8 to bit positions of the frame data FRMD respectively corresponding to the linear scale and the rotary encoder. At the bit positions where the encoder signals ENCD1 to ENCD8 are set, the encoder signal ENCD and information showing the presence or absence of the data of the encoder signal ENCD are alternately set for each cycle of transmission of the frame data FRMD.Type: GrantFiled: October 9, 2013Date of Patent: March 13, 2018Assignee: FUJI MACHINE MFG.
