Description

technical field [0001] The invention relates to a network platform, in particular to a multipurpose wireless sensor network platform based on a single-chip microcomputer. Background technique [0002] The wireless sensor network node hardware platform is mainly composed of main control chips, wireless communication modules and peripheral circuits, etc., and generally has the characteristics of small size, low cost and low power consumption. At present, the commonly used hardware platforms are divided into two types: integrated type and split type. The integrated platform is mainly a hardware device made by using TI's CC2430, CC2530 and other main control components and a wireless single-chip microcomputer combined with a radio frequency unit; Early MicaZ nodes composed of ATmega128 and CC2420, and other platforms designed and built using 8051 single-chip microcomputers and RF modules. [0003] As for the all-in-one hardware platform, it has high working efficiency and good...

Problems solved by technology

Although some nodes provide a variety of power supply methods, most of the different power supply methods are switched by jumpers, which is troublesome to use and affects the service life of the node hardware; while some platforms do not have switching devices and do not provide protection measures. Connecting other power sources will cause the external power source to charge the dry battery, which may cause an explosion and cause an accident

[0007] To sum up, the currently commonly used wireless sensor network platforms have the disadvantages of secondary development difficulties, low performance of the main control single-chip microcomputer, and inability to realize independent collocation. High, efficient and safe wireless sensor network platform that can realize hardware selection and matching
