Aiming at various water storage facilities, the number of which is generally large and whose distribution is not centralized in the industrial and civil buildings, this paper proposed a multi-channel water level telemetry and low power automatically warning system based on wireless sensor network. The sensor nodes of the proposed system could monitor water levels and transmit sensing data to the sink node periodically. The host server analyzed sensing data received from the sink node. Meanwhile, it made decisions according to the multi-grade cycle comparison algorithm proposed in this paper to improve the alarm accuracy. Experiment result indicated that it could not only improve the alarm sensitivity of the system, but also avoid error judgment to a large extent. When a leakage emergency happened, the host server sends an alert message to the alert terminal, through the sink node. In addition, SMS server is added to the system architecture to automatically send emergency messages to related emergency processing offices for dealing with it timely. The design of sensor nodes adopts the sensing data selective transmission mechanism and the node transmission power adaptive mechanism to reduce power consumption. The experiment result indicates that the energy reducing effect is significant. The communication performance of the system network was tested and the experimental results show that the system has good reliability and real-time performance. By testing the system operations, the good performances of alarm accuracy and low power are verified. © 2013 Engineering and Technology Publishing. |
