摘要:
A data collection system includes a plurality of sensor modules each provided with a sensor unit, and a data collecting device. The data collecting device (200) is provided with: a clock output unit (201) which outputs a clock signal; an enable signal output unit (202) which outputs to a prescribed sensor module (100) an enable signal at intervals equal to or greater than the number of clock signals corresponding to the number of sensor modules (100); a counter (203) which counts the number of clock signals; and a sensor signal input unit (205) into which data output by the sensor modules (100) is input via a bus line, and which records said data in association with the count value. Using the clock signal as a trigger, each sensor module (100) functions as a shift register feeding the enable signal to the subsequent stage sensor module (100), and each sensor module (100) outputs output data from the sensor unit (110) in said sensor module (100) to the sensor signal input unit (205) only when the enable signal has been fed to said sensor module (100).
摘要:
Provided is a conveyance control system in which fast and smooth control is realized without causing a control delay by a processing delay of a control apparatus such as a PLC, and wiring between a control object and a central control unit is omitted. A conveyance control system according to the present invention includes a plurality of data processing slave stations connected through a common transmission line. The data processing slave station obtains information about a predetermined station from monitor/control data about a plurality of stations of the data processing slave station transmitted to the common transmission line, determines and adjusts control/monitoring of an own station and outputs information about an own station to the common transmission line. The information about an own station output to the common transmission line from the data processing slave station is obtained by a different station as part of the monitor/control data to become a control/monitor factor of the different station.

A parent station output section changes a duty factor between a period in which a control data signal is at a level (high-potential low-level) lower than a power supply voltage Vx but higher than high-level signal in other circuit portions and a subsequent period in which the control data signal is at the power supply voltage Vx level to convert the control data signal into a serial pulse voltage signal and output the voltage signal onto data signal lines D+ and D− in accordance with each data value in the control data signal inputted from a controller in each cycle of a clock.
