According to one embodiment, a conveyor diagnostic device diagnoses an abnormal state of a cyclically moving conveyor. The conveyor diagnostic device includes a first tilt sensor, a second tilt sensor, a table, and a processing unit. The first and second tilt sensors are attached to a predetermined position of the conveyor and detect tilt angles of the conveyor in a vertical direction and horizontal direction, respectively. The table indicates a relationship between a tilt angle which changes in the vertical direction and sections included in one revolution of the conveyor. The processing unit specifies an abnormality occurrence position of the conveyor based on a tilt angle in the vertical direction, the table, and an elapsed time after ingression for a section corresponding to the tilt angle in the vertical direction, when a tilt angle in the horizontal direction exceeds a predetermined management limit value.

Conveyor diagnostic device and conveyor diagnostic system

According to one embodiment, a monitoring/diagnostic apparatus is provided, which is designed for use in a system for monitoring and diagnosing a plurality of object devices. The monitoring/diagnostic apparatus has an agent management module and a diagnostic module. The agent management module is configured to manage agents for collecting operation data of an object device. The diagnostic module uses the operation data collected, thereby to diagnose a problem in the objective device.

System for monitoring and diagnosing remote devices

Disclosed is a remote monitoring diagnostic system in which a center and monitoring diagnostic units of a number of objects to be monitored are connected by a network. The center includes an algorithm forming unit for forming algorithms for monitoring, diagnosing, and operating each object to be monitored, a program group formation unit for forming monitoring, diagnostic, and operational programs from these algorithms, a transmitter for transmitting the programs in response to a request from the monitoring diagnostic unit, and a unit for forming information concerning prevention/maintenance form a diagnostic result and monitoring data from the monitoring diagnostic unit of each object to be monitored. The monitoring diagnostic unit of each object to be monitored includes a mobile program execution processor for executing the corresponding object to be monitored, and a transmitter for transmitting monitoring data to the center.

Remote monitoring diagnostic system

A system for performing remote supervision and diagnosis, having a plurality of local terminals for performing supervision and diagnosis on an object, by executing a mobile program transmitted from a central system. When a disaster occurs and the network is cut, inevitably disconnecting the local terminals from the central system, one of the local terminals is set as a representative local terminal. The representative local terminal collects from the local terminals the maintenance information required for supervising and diagnosing the object.

System for remote supervision and diagnosis using mobile program

To provide an entry control system as well as an entry control method allowing for an easy entry of user, permitting a restriction to persons who have a legitimate right to enter a facility, an illuminating device () emits a modulated visible light signalmodulated by use of a door ID code into a preset illumination range, the modulated visible light signalfrom the illuminating device () is received by a mobile terminal () portable by the user, where it is demodulated for wireless signal transmission, and the door ID code transmitted from the mobile terminal () is received by an authentication device (), which judges whether or not the door ID code is legitimate, and generates an unlock command when the door ID code is judged to be legitimate, and a door () for a facility controlled of entry receives the unlock command from the authentication device (), whereby it is unlocked.

Entry control system and entry control method

A center-side processing system and monitoring processing systems of monitoring objects are connected through a network. The center-side processing system includes a module for producing monitoring and diagnostic algorithms of the monitoring objects, software producing module for producing monitoring and diagnostic software from the monitoring and diagnostic algorithm, a module for producing a transmission schedule of the monitoring and diagnostic software, transmitting module for transmitting software according to the transmission schedule, a module for correcting and changing the monitoring and diagnostic software from data received from the monitoring processing system, and verification module for performing verification before the transmission of the monitoring and diagnostic software. Each of the monitoring processing systems includes a module for receiving the monitoring and diagnostic software, execution processing module for executing the monitoring and diagnostic software, a module for automatically verifying the monitoring and diagnostic software, and transmitting module.

Remote monitoring and diagnostic system

A system for transmitting data between a plurality of linked stations within a cycle period defined by successive transmissions of a header signal indicating the start of a data transmission, only one station having a right to transmit data at a given time, the data including a first portion for which real-time characteristics are required, and a second portion for which real-time characteristics are not required. Each station includes a transmission circuit for transmitting the header signal and the data to another station, a receiver circuit for receiving the header signal and the data from another station, and a control circuit for assigning the right to transmit data serially to each station in a prescribed order two times within each cycle period and for transmitting the first portion of the data separately from the second portion of the data. The first portion of the data is transmitted the first time that the right to transmit data is assigned to the station.

Data transmission system and method for transmitting data having

A system of transmitting data and frame signals distinguishable from the data between a plurality of nodes linked in ring form. Each node comprising two transmitter circuits for simultaneously transmitting data and frame signals in opposite directions, respectively, two receiver circuits for receiving the data and the frame signals from opposite directions, respectively, a priority circuit for selecting the data first received from the two opposite directions, a frame circuit for detecting receipt of the frame signals and generating frame signals, and a control circuit for detecting data transmission faults and supervising data transmission of the system according to the location of the fault in the system, in response to the frame signals.
