The fault diagnosis technology have emerged and developed rapidly with the development of wireless sensor networks and requirements of applications improve. This paper describes two commonly used sensor network fault modeling. What is more, in order to solve this problem that sensor nodes are vulnerable and therefore produce wrong data, the paper proposes a distributed fault detecting algorithm based on spatio-temporal correlation among data of adjacent nodes. The simulation experiment shows that the algorithm can efficiently detect errors in the network and very few errors are introduced.

Positioning hydraulic system failure rate is high, the fault detection difficult. This paper introduces the involvement type hydraulic system the basic principle of measuring technology, hardware design and software design. The interventional type hydraulic detection method to overcome the traditional type detection method increased the complexity of the hydraulic system fault, without using the reserved interface. Research on fault diagnosis technology of hydraulic system of the intervention is very important for the development of the hydraulic system fault diagnosis.
