Research on Application of 1-Wire Bus Technology in Long Distance and Multi-Spot Temperature Monitoring

According to the request of the application environment of long distance and multi-spot temperature system, the author proposes the method of forceful actuation temperature monitoring about the 1-wire bus´s field. By designing one driving circuit with proper rate of drop-down and drop-up, the driving force of the temperature monitoring can be enhanced greatly so as to support the multi-spot temperature monitoring in a longer distance, a bigger space and simultaneously realize the separation between the monitoring pattern and the searching pattern. In this way, we can avoid the occurrence of monitoring chaotic situations because of the lose of sensors thus guarantee the monitoring network´s reliability, stability and intelligence, enabling the 1-wire bus monitor to be applied in a bigger scope.
