Description
ACI Wireless Sensor Network is the wireless sensor network system which is research and developed by ANCN. It can be the substitute for traditional sensor data acquisition system. The system is composed of ACI-2 Wireless communication terminal, ACD series wireless digital pressure gauge and ACT series wireless digital temperature gauge. The free ISM frequency is used for data transmission. The instruments are provided with built-in battery, so no wiring is required for connection between the instrument and communication terminal. The communication terminal and industrial control machine are connected by RS485 OR RS232. Standard MODBUS-RTU communication protocol is adopted, so Kingview, Intouch, FIX and other industrial control software are supported; data communication with equipment and system of SIEMENS, Kreuznach, ABB and other famous brands can be realized; currently the stable acquisition of 50 sets ACD wireless instruments within 200m or 800m radius can be realized.
Wireless sensor network is widely used in military, industrial control, medical care, environmental monitoring, smart home, building condition inspection and other fields.
Application
l Unique process monitoring technology
l Applicable to sites which require frequent manual meter reading
l Requires equipment with high frequency monitoring (reading per about some seconds and multiple of 10 seconds)
l Require sites with multi-point pressure and temperature
Features
l Wireless transmission, no site wiring is required, and both external problems of the labor power and construction costs are saved.
l Instrument of wireless sensor network adopts lithium battery with large capacity and high performance, no external power is required, the instrument is especially applicable for the open area without power supply.
l Quantity of wireless sensor instrument can be expanded with certain scope, the adjustment is easy;
l High acquisition precision, stable transmission and less network maintenance;
l Star topology structure bus, sensors have no impact on each other, simple maintenance;
l Communication terminal and wireless instrument adopt lightning protection and explosive-proof designs, which are applicable to various severe climates and data communication and acquisition of gas gathering station.
