The DACS (Data acquisition and control system) in this particular case is based on Acura Embedded EIPs (Embedded Intelligent Platforms). Composed of AcuBrite industrial monitors and PowerBrick rugged computers, the system can acquire and manage the data from different sensors, switches, relay, pump, and so on. The communication between the subsystem and the server is based on TCP/IP protocol.
In a factory, various subsystems are required to be integrated together, such as a substation, railway, process control in the production line, equipment monitoring, and so on. Acura Embedded’s DACS is widely used in the detection, control, optimization, scheduling, management to improve product quality and output. It mainly consists of three parts: software, hardware, and operating system.
You can easily configure a DACS to meet your needs for monitoring and control. The DACS is set up to handle many different digital/analog signal inputs/outputs.
DACS can be structurally divided into three parts: Upper Computer, Lower Computer, and The Upper Computer is composed of high-stability and high-reliability EIPs; while the Lower Computer consists of PCI data acquisition and control card, accompanied terminal board and signal lines between them, all of which can be selected to meet customers’ specific requirements for the quantity and type of acquisition signals and control signals. The Server adopts a high-reliability All-in-one Compact PCI Platform.
Signal Flow: After acquiring digital or analog signals, the terminal board transfers them to PCI data acquisition and control card. After being amplified, the processed signals are to be transferred via PCI bus to the Upper Computer for DACS software analysis and processing, during which corresponding control commands can be generated. If the signals analyzed and processed are abnormal ones, the alarm would be triggered, thus achieving monitoring of terminal devices. Or after analyzing the abnormal signals directly, the system generates a series of commands to control PCI data acquisition and a control card which generates TTL control signals. After being amplified, the TTL control signals are transmitted via terminal boards to corresponding terminal devices, thus realizing control of terminal devices.
The information processed by the Upper Computer is real-time transmitted to the server via a network for data backup, which upgrades the reliability of the system. Each substation in the system can be monitored and controlled by the Server, thus realizing real-time monitoring and control of the whole system, and facilitating software upgrade. This server can be widely applied in electric power control systems, an automatic control system of a flow production line, etc.
