Comprehensive management system of open type laboratory

Abstract

The invention discloses a comprehensive management system of an open type laboratory. A server is in a bidirectional communication with at least one ARM (Advanced Risc Machine) client; each ARM client is connected with a corresponding RFID (Radio Frequency Identification Devices) reader-writer and is at least connected with a power supply control module. The power supply control module using a zigBee nodes is used for ZigBee wireless communication by using a mesh network to control an experiment table to be automatically powered-on or powered-off, to monitor whether the electric leakage of the experiment table occurs or not, and to give an alarm, so that the information interaction between a teacher's experiment table and students' experiment tables can be realized. During the B / S (Browser / Server) communication and the C / S (Client / Server) communication, an encrypting algorithm of multi-Hash operation combined with random numbers is used for acquiring data of the server to guarantee that the user information cannot be acquired even if the communication data is intercepted and captured; the data communication of a C / S framework adopts a communication method with complete and reliable data encapsulation and resolution, so that the stability and reliability of the system can be improved. The comprehensive management system of the open type laboratory, disclosed by the invention, is simple to use, energy-saving and efficient, strengthened in safety assurance, and stable and safe in operation.

Description

technical field [0001] The invention belongs to the field of embedded, wireless communication and computer, and provides a complete set of open laboratory comprehensive management system. Background technique [0002] Cultivating research-oriented and innovative talents has become the common goal of talent training in the world's outstanding universities. Therefore, practical teaching is becoming more and more important in higher education. Therefore, building an open laboratory that provides students with hands-on practice and technology production has become the goal of many universities. important work. The open laboratory can be opened to collective experiments with the class as the unit, and can also be opened to individual experiments by students and teachers. [0003] Due to the randomness of the time and number of people using the laboratory, the traditional mode of having a special person on duty in the laboratory cannot predict the number of people participating i...

AI Technical Summary

Problems solved by technology

[0003] Due to the randomness of the time and number of people using the laboratory, the traditional mode of having a special person on duty in the laboratory cannot predict the number of people participating in the experiment and the experiment time, which not only increases the burden of the experiment administrator, but also brings inconvenience to teachers and students , and there is no guarantee of laboratory utilization

At present, there are also new laboratory management systems, such as the Chinese patent "Open Laboratory Management Information System" with the publication number 101789107, which realizes functions such as online reservation and laboratory online management, but this patent mainly focuses on the realization of functional modules. Aspects such as security and communication reliability are rarely involved
