Security authentication system for country biogas data collection terminal

Abstract

The invention discloses a security authentication system for a country biogas data collection terminal. The security authentication system comprises modules such as a master controller module, a radio-frequency module, a power module, an interface module and a crystal oscillation module as well as an antenna switch, a security authentication module and a biogas device; the master controller module comprises a master controller, an operation module and a storage unit; the radio-frequency module is responsible for sending and receiving wireless data; the interface module is connected to an input-output interface of the master controller and an interface of an external circuit; the antenna switch is responsible for switching an antenna channel; the power module provides an electrical energyconsumption for each of sub-modules inside the modules and for a circuit unit; the crystal oscillation module provides a crystal oscillation frequency for the radio-frequency module and the master controller; and the security authentication module performs security authentication on data received via an air interface from the master controller, and data of the biogas device from the interface module, passes through the data that are correct and legal, or otherwise intercepts the data. According to the security authentication system, the independent security authentication module is designed to perform checking and authentication on input-output data of the biogas terminal; and the security authentication system can be independently dismounted.

Description

technical field [0001] The present invention relates to a wireless network system, in particular to a security authentication system for rural biogas data collection terminals. Background technique [0002] In rural areas with vast land and sparsely populated areas, biogas data collection is traditionally done manually, and staff members copy biogas usage data from door to door, which is very laborious and inefficient. Later, with the development of wireless network technology, some people put forward the scheme of using the public network for wireless data transmission, that is, using the operator's network for long-distance data transmission. This solution is to use the existing wireless network to realize data transmission, which saves a lot of costs for setting up base stations and network equipment. Although wireless transmission is convenient, how to ensure the safety and correctness of information during wireless transmission has become the key to wireless data trans...

AI Technical Summary

Problems solved by technology

Wireless transmission often receives various interferences from the environment, and the received data may be wrong or incomplete. In addition, it is also necessary to prevent someone from tampering with the communication system by using the data in the air, thus causing the loss of the wireless biogas data acquisition system.
