| Abstract: | The researching situation of gas sensors at home and abroad is introduced and the structure of gas sensor detecting system based on DeviceNet Bus is provided. The character of DeviceNet Bus protocols and its key technology are analyzed briefly. The designing plan for mine gas sensor based on DeviceNet Bus protocols is put forth, whose hardware circuit mainly includes signal modulators, digital signal processor and interface circuits fulfilling the communication of DeviceNet. Then, the object model of mine gas sensor is constructed by the method of object modeling, and the software design for mine gas sensor being applied as a salve instrument of the network is accomplished by use of modularized programm technique. The sensor can realize remote-control of the data from many mine gas sensors when it connects as a slave instrument with the computer with PCI-CAN network card. |
