Distribute Controll System

This system is total control system which shares only necessary information and resolves overconcentration of the controlling. For example, a building blind control. This blind system constructed by 3 types of device, and designed for distributed control network system.
The control network system is organized by terminal device controller, parent unit which control these terminal device controller group, relay device for sensor which gathering environmental data from outside, and PC for monitoring and setting at highest hierarchy.
These devices are controlling, connected by typical TCP/IP network or 485 communication system, depending on the scale, using originally developed hardware.
Central control PC, control parent unit and relay device for sensor are connected by typical TCP/IP network. And, the central control PC function is only for setting and monitoring condition of each device and not doing any controlling. Regular controlling is done by control parent unit. One parent unit is able to support maximum 256 terminal device controllers with daisy chain by 485 communication system using originally developed hardware.
The relay device for sensor collects multiple information suchlike solar radiation, illumination and outside temperature, and issue command to each parent unit via TCP/IP network corresponding environmental changes.
Our company is developing and manufacturing all required device in this network and developing software for central control PC, developing controller software using C language stand with OS for parent unit, and developing firmware for terminal device controller.
In this way, KSJ implemented the big scale network system with 5000 terminals by developing requested hardware and software by customer.
