This paper presents the design and implementation of universal low cost data collection module (DCM), which is an essential part of remote monitoring system based on wireless sensor network. The proposed module expands the capabilities of a measuring node for collecting data from greater number of sensors. The DCM includes four parts: one group multiplexers for data acquisition, second group multiplexers for power management, voltage to current converters and DC/DC converters. The universal DC/DC converters provide autonomous power supply for the sensors and the multiplexers, which can be turned on or off for a certain period of time. The data collecting, monitoring and logging functions are realized through a LabVIEW project.The proper operation and the reliable performance of the system were proved by practical experiment. The proposed module makes the WSN-based system a versatile solution for a variety of monitoring applications.

To solve the writing and reading operation conflict to RAM in LED/LCD display control system, a new RAM operation conflict arbiter IC was proposed. Comparing the traditional dual ports RAM, the IC has the advantages of low-cost and high stability. By analyzing the working principle and structure design, the IC was designed in pure digital way with Verilog HDL, and passed the simulation verify. Finally the IC was realized by Alter FPGA chip and passed the actual test.

Computing Structure

The theory of federal filter based on the Kalman filter is investigated in the design process, as well as the federal filter information distribution. Considering the advantage of parallel computing structure, the FPGA chip is selected and used to realize the IP core encapsulation and design of Federated Filter. The filtering speed is greatly improved to meet federal filter integrated navigation system. A group simulation experiments are conducted. The results shown that the filtering accuracy and filtering time of federal filter are both improved using the proposed method.
