Embodiment 1

[0082] Example 1: Node Energy Saving Test

[0083] In order to study the actual energy-saving status of nodes under the hardware sleep mechanism, the present invention designs the following experiments.

[0084] Test purpose: to test the energy saving of the node when the hardware is scheduled to sleep.

[0085] Test environment: There are normal interferences such as computer equipment and personnel.

[0086] Test equipment: It consists of a coordinating node and a routing node, among which JN5148-M00, JN5148-M03, and JN5148-M04 are used as the transmission modules of the nodes.

[0087] Test plan: the routing node is placed 1m away from the coordinating node, and the routing node sends a data packet to the coordinating node every 1000ms, and each data packet contains 13 bytes of information. Measure the energy consumption of the node when the node is in hardware sleep and when it is not in hardware sleep. When the hardware sleep mechanism is adopted, the working and sle...

Embodiment 2

[0091] Example 2: Single node data transmission test

[0092] In order to verify the performance of the designed indoor temperature and humidity sensor network system: reliability and effectiveness, this test will follow the gradual increase of test interference and network complexity to verify the test, verify the reliability and accuracy of data transmission sex. Through the single-node test, the transmission distance and data loss of a single module of different types of chips can be counted, and the data communication situation in the "multi-hop" mode can be measured through multi-node networking. Through the above research and test the influence of different obstacles on the network in the room, the networking capabilities of the nodes can be summarized, which provides an experimental basis for the real use in the building, and effectively and reasonably deploys the nodes.

[0093] Through single-node data transmission test, simple topology test under JNET protocol, co...

Embodiment 3

[0101] Example 3: Complex network structure networking test

[0102] (1) No personnel interference network test.

[0103] This experiment is composed of a coordinating node 10, three routing nodes 7-9 and six underlying nodes 1-6, in which the communication module of the coordinating node adopts a high-power M04 chip. Combined with the results of the last experiment, in order to increase the reliability of transmission, both the routing node and the underlying node use the M03 chip with an external antenna. This test experiment will use the mesh network topology of the ZigBee protocol for networking. The location and distance of each node are as follows: Figure 16 shown. Because this system is applied indoors in buildings, the test site of this experiment is the Electrical Intelligence Experiment Center of Beijing Institute of Civil Engineering and Architecture. The test time is 23 o'clock in the evening for testing. There is no human interference during this time period,...

Abstract

The invention discloses an intelligent wireless network sensor system possessing power supply management and belongs to the instrument and meter detection technology field. Wireless sensor nodes in the system comprise ground floor nodes, a routing node and a coordination node. The ground floor nodes are distributed on each monitoring point. According to a Zigbee protocol, the routing node and the coordination node are communicated with an upper computer so as to realize real-time control of a network. Each sensor node is formed by a base circuit, a core module, a function circuit and a power supply management module respectively. In the invention, based on a PIC single chip microcomputer, through using a mode of controlling on and off of a load power supply, about 70% average node power consumption is reduced; a dormancy mechanism is added in the nodes and on and off of a node load power supply are controlled in a fixed time mode; micromation, low power consumption, low cost and other characteristics are possessed; the nodes possess certain anti-interference performance and high robustness of adaptability; an expansion interface is reserved in the nodes and scalability is high.

Description

technical field [0001] The invention belongs to the technical field of instrument detection, and in particular relates to an intelligent wireless network sensor system with power management. Background technique [0002] With the development of computer and information science and technology, the demand for intelligence in different fields such as military defense, precision agriculture, medical health, safety monitoring, environmental protection monitoring, construction, traffic flow, and smart home is also increasing. The ensuing problems of information collection, acquisition, data transmission and storage are highlighted. Wireless sensor network (Wireless SensorNetwork, WSN) is able to deploy many small and cheap sensor nodes in the unattended monitoring area, and form a multi-hop, environment adaptive "intelligent" measurement and control network system through wireless communication. It can be applied to areas where wiring, power supply is difficult, and where people ...
