In view of the current status and shortcomings of existing meter reading systems, in this paper, we proposed an automatic gas meter reading system based on the advantages of gas meter directly reading technology, WSN technology and GPRS technology, introduced the whole scheme and the design of hardware and software in detail. The system is consist of three level network. The first level network and the second level network use the different frequency during communication. It decreases the interface of each other during the translation of the data, and increase the lifetime of the smart gas meter. The system has the advantages of easy construct, flexible layout, lower power consumption
Slip resistance of footwear sole affects the comfort and safety of shoes directly, and slip resistance is mainly expressed by the coefficient of friction. Within a certain range, the greater the coefficient of friction, the better the slip resistance. In order to determine the safety performance of shoes, the system will obtain the coefficient of friction by measuring the tension and pressure put on shoes, so it’s very important to do the measurement precisely. Based on QT development environment and Monitoring-controlling System of footwear sole friction, the software will execute real-time receiving, processing, controlling, displaying, drawing and saving collected data of tension and pressure via serial communication and finally on the basis of the system test to verify the correctness of the software and measurement accuracy
In order to collecting, analyzing and processing the shearer body’s vibration data, we use Labview for data acquisition and signal analysis. By the computer to complete a range of its functions. Instead of the traditional instruments, Labview has a better programming convenience, strong function and flexibility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
