Abstract

The invention relates to the technical field of wireless sensor networks, and particularly relates to a lightweight high-speed wireless sensor node. The lightweight high-speed wireless sensor node comprises a shell, a first circuit board, a second circuit board, a wireless communication module and a connector, wherein the first circuit board and the second circuit board are arranged in the shell in parallel, the wireless communication module is arranged below the second circuit board, and the first circuit board, the second circuit board and the wireless communication module are connected via the connector; wireless sensor node circuit chips are arranged on the mutually departing sides of the first circuit board and the second circuit board, the wireless communication module is provided with the wireless sensor node circuit chip on the side away from the second circuit board, a plurality of bosses are arranged on an upper cover plate and a lower cover plate of the shell, the wireless sensor node circuit chip on the first circuit board is respectively propped against the boss on the upper cover plate, and the wireless sensor node circuit chips on the second circuit board and the wireless communication module are respectively propped against the boss on the lower cover plate. The lightweight high-speed wireless sensor node provided by the invention can reduce the device size, as well as quickly dissipate heat.

Description

technical field [0001] The invention relates to the technical field of wireless sensor networks, in particular to a lightweight high-speed wireless sensor node. Background technique [0002] Industrial wireless sensor network technology is another hot technology in the field of industrial control after fieldbus. It is a revolutionary technology that reduces the cost of industrial measurement and control systems and improves the application range of industrial measurement and control systems. It is also a new growth point for industrial automation products in the next few years. In the field of factory automation, due to the large number of sensors required by the system and the high real-time and reliability requirements of the system, the existing wireless sensor network nodes based on single-chip or other low-performance CPUs are far from meeting the performance requirements of factory automation. In order to meet the real-time and reliability requirements of factory autom...

AI Technical Summary

Problems solved by technology

In order to meet the real-time and reliability requirements of factory automation, higher-performance CPUs and high-speed peripherals need to be used, but with the improvement of CPU performance, the complexity of the system will inevitably increase, which brings two problems: on the one hand, high-performance The size of the CPU and its peripheral wireless sensor node circuit chips is generally relatively large, and the nodes produced are generally relatively bulky, which is not suitable for field application in factory automation; on the other hand, high performance will inevitably bring high power consumption, and heat dissipation has become A relatively big problem. In order to ensure the long-term and reliable operation of the CPU, it is generally necessary to install heat sinks and fans, which further increases the size of the node.
