Problems solved by technology

[0002] There is only one input terminal in the circuit structure based on the wireless sensor network, and the measured value of the wireless output cannot be input to the secondary wireless sensor node to change the node state. Therefore, the UIO method of the wireless input and output test case lacks hardware foundation and cannot be found sensor failure

Embodiment Construction

[0044] The physical name of the input signal intensifier varies with each wireless sensor, for example, for a wireless temperature sensor, it is a heating coil connected to the measuring head of the wireless sensor.

[0045] The present invention synchronously sends a group of starting pulses of the same specification to each wireless sensor through the central controller, so that each starting pulse can start the input signal intensifier connected to each wireless sensor measuring probe through each triode switch pulse circuit, and increase the effect on The input pulse amplitude value on the measuring probe makes each wireless sensor turn from the idle state to the running state, and the corresponding wireless sensor CPU w Then send their respective IP addresses to the central controller, indicating that they are in the running state; for nodes with no signal output, the central controller will determine them as faulty nodes, and according to the IP addresses of the faulty no...

Abstract

The invention discloses a fault discovery and rapid alarm method for a wireless sensor network, and belongs to the field of wireless sensor network operation. The central radiation network is composed of a central control node and all wireless sensors, and the worm network is formed by connecting storage servers through optical cables in series up and down through the wireless sensors. In idle time, the central controller sends out a group of starting pulses to start the wireless sensors through the input signal intensifiers on the probes respectively, and the central control node discovers all fault nodes in the network at one time according to whether a response signal is received or not; during normal operation, any two adjacent nodes not only transmit information in the shortest path at the fastest speed and send the information to the central control node or other nodes through the worm network or / and the central radiation network, but also can actively call the next node to find a fault node during transmission, so that the whole-process detection is realized.

Description

technical field [0001] The invention belongs to the field of wireless sensor network operation, in particular to the technical field of finding faulty nodes. Background technique [0002] There is only one input terminal in the circuit structure based on the wireless sensor network, and the measured value of the wireless output cannot be input to the secondary wireless sensor node to change the node state. Therefore, the UIO method of the wireless input and output test case lacks the hardware foundation and cannot be found Sensor failure. Contents of the invention [0003] The purpose of the present invention is to provide a wireless sensor network system in the idle state, normal operation state or sick operation state to find a fault and quickly alarm method, which is a method of early warning and information transmission in the whole process. [0004] The present invention is characterized in that, 1, a kind of method for fault finding and rapid alarm of wireless senso...
