would send the surveillance exception information to PC client,
and then PC client would direct PDA client to carry out the
work of fieldwork investigation and emergency response.
Meanwhile, the database service of collaborative server is
providing continuous data and information exchange service for
server, PC client and PDA client. Figure 2 shows the
collaborative working flow of prototype system.
Figure 2. Collaborative working flow of prototype system
Real geographical data and simulating disease data are used in
this experiment of prototype system, and spatial scan statistics
results of surveillance module in different scales are shown in
Table 2. Moreover, Figure 3 shows the epidemical surveillance
computing program of collaborative server, including multi
scale surveillance computing results. Intelligent disease
diagnosis module and fieldwork response module of PDA client
are shown in Figure 4 and Figure 5 respectively.
