Description of drawings
The building-block of logic of the wireless sensing network system that Fig. 1 provides for an embodiment who the present invention relates to;
Fig. 2 detects the workflow diagram of the transducer on its node interface of identification automatically for wireless sensing network system shown in Figure 1.
Embodiment
Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing.
See also shown in Figure 1ly, an embodiment of the invention provide a kind of wireless sensing network system, and it comprises node, and wherein node is provided with sensor interface and is used for connecting transducer.The quantity of the sensor interface of each node setting can be one, also can be a plurality of, decides with the need.Node also can arrange indicating device, is used to indicate its interface and whether is connected with transducer.
The transducer that connects includes 2 lines and/or 3 line analog sensors and intelligence sensor (Smart transducer).Be provided with system information (Sensor Identification Structure, SIS information) in these transducers, it comprises the supply power mode of transducer, the stand-by period that powers on, sampling stand-by period and sensor type etc. information.
Further, can set up on their own according to actual needs for these system informations.Be example with sensor type information, it can be to be stored by the space of a byte-sized, the number of this byte can be got any number between 0 to 255,256 type of sensor so just can be set, similar identity card ID is called for short Sensor ID, and each transducer has and have only a Sensor ID, in the wireless sensing network system, the transducer kind of use can be above 256.This method shows every kind of type of sensor in the client of system very easily.
For 2 lines and/or 3 line analog sensors, these system informations be by the 1-Wire programming in the EEPROM of analog sensor, and EEPROM is arranged in the interface or interface board of transducer.And for intelligence sensor, it is that EEPROM is not set, and the system information in it sends to system by RS485.
See also shown in Figure 1ly, it has shown the operational process of the wireless sensing network system that the present invention relates to.At first, system starts the WSN node, and node begins its interface of automatic scan, determines whether to be connected with transducer.And the program of node maintains the original state when node interface is added the transducer of new connection.
As shown in FIG., be the SIS information that reads.For analog sensor, read the system information among its EEPROM exactly.And for intelligence sensor, then be to send the SIS querying command by RS485, receive the SIS information that intelligence sensor sends then.
System can notify its indicating device after knowing SIS information, for example, and lighting fixture; If there is transducer to connect, then green light is bright, if do not have, then red light is bright.
