Describe data transmission device 120 carries out transfer of data between upper network 110 and the next network 130 handling process in detail below with reference to Fig. 4～Fig. 7.Wherein, Fig. 4～Fig. 5 relates to the data transmission and processing from the next to upper, and Fig. 6～Fig. 7 relates to the data transmission and processing from upper to the next.Wherein, from the next to upper, refer to obtain the process of management information, be specially data transmission device 120 and will be forwarded to after treatment from the status data that the next network 130 is obtained upper network 110; From upper to the next, refer to the process that basis is set from the control command of upper network 110, comprise that data transmission device 120 changes the attribute data of storing in self storage part 124, also comprise the control command that sends in order to control being monitored object to the monitor 131 of the next network 130.
Fig. 4 shows the flow chart of the first embodiment of the data transmission and processing from the next to upper.In the first embodiment, the office terminal 113 in the upper network 110 sends to obtain the query requests 240 of management information in the mode of poll to the next side, to manage all monitors 131 in the next network 130.
As shown in Figure 4, if receive to obtain the query requests (S01) of management information from upper network 110, then start the data transmission and processing from the next to upper.Subsequently, the monitor 131 in the next Department of Communication Force 123 and the next network 130 communicates, and receives the status data (S02) that expression is monitored the situation of object with the monitor 131 from the next network 130, and status data is sent to data processing division 122.
Then, 122 pairs of data processing divisions are analyzed from the status datas of the next Department of Communication Force 123 inputs, with identification corresponding with status data be monitored object (S03).The concrete processing procedure of step S03 can be, data processing division 122 is judged address included in the query requests that step S01 receives and the corresponding relation between the status data, thereby can determine according to this corresponding relation the source address of status data, and identify the object that is monitored that is associated with this status data based on this source address.Wherein, identification is monitored object and can be specially type and the numbering of determining to be monitored object.The type that is monitored object comprises the input of DI(numeral), the output of DO(numeral), the input of MI(multimode), the output of MO(multimode), the AI(analog input), AO(simulate output) and PI(measure input) etc.The numbering that is monitored object is monitored object and is monitored position in the object in all of same type in order to represent this.Also namely, can uniquely determine one according to type with numbering and be monitored object.
Then, data processing division 122 is according to the type that is monitored object and the numbering that identify, read from storage part 124 and to be monitored attribute data (S04), state-based data and the attribute data that reads generate and comprise the management information (S05) that is monitored the object full detail, and the management information that generates is sent to upper Department of Communication Force 121.
By above-mentioned introduction as can be known, can comprise at least as shown in Figure 9 analyzer 1221, attribute data reader 1222 and management information synthesizer 1223 according to the data processing division 122 in the data transmission device 120 of the present invention.Wherein, analyzer 1221 is used for the status data 230 from the next network 130 is analyzed, to identify the object that is monitored that is associated with this status data; Attribute data reader 1222 is used for reading from storage part 124 based on the information that is monitored object that identifies (for example, being monitored the type of object and numbering etc.) and is monitored attribute data 220; And management information synthesizer 1223 is used for status data 230 and attribute data 220 are synthesized the management information 210 that comprises the full detail that is monitored object.
Subsequently, the office terminal 113 in upper Department of Communication Force 121 and the upper network 110 communicates, being sent to upper network 110(S06 from the management information of data processing division 122 inputs).So far, the data transmission and processing from the next to upper routine finishes.
Although in the first embodiment, start data transmission and processing from the next to upper by the query requests that is issued to obtain management information by upper network 110.Yet, the invention is not restricted to this particular implementation, for example, data transmission device 120 also can be configured to comprise following function, namely carries out the data transmission and processing from the next to upper when the status data that receives from the next network 130 satisfies predetermined condition.
Fig. 5 shows the flow chart for the second embodiment of the data transmission and processing from the next to upper of this situation.
Compare with Fig. 4, Fig. 5 has omitted step S01, has increased step S031 and S032 simultaneously between step S03 and S04.The below will omit the repeat specification to same section, and only describe the difference of Fig. 5 and Fig. 4 in detail.
At first, by omitting step S01, so that the executive condition of the second embodiment is no longer dependent on the query requests that receives to obtain management information from upper network 110.
Secondly, according to the second embodiment, by between step S03 and S04, having increased step S031 and S032, so that data processing division can send warning information etc. to upper side immediately when each status data from the next network 130 satisfies predetermined condition, thereby can in time tackle various emergencies, and needn't wait until that poll regularly.
Particularly, be monitored accordingly object (S03) afterwards in the state-based data identification, data processing division 122 according to the information that is monitored object that identifies (for example, be monitored the type of object and numbering etc.) status data is processed (for example, carrying out numerical value conversion etc.) situation (S031) to determine to be monitored object.Subsequently, judge that whether the determined situation that is monitored object satisfies the predetermined condition (S032) of expression emergency, if satisfy, then continues follow-up step S04～S06 with the management information of immediately transmission expression emergency, otherwise directly finishes.Wherein, be applied to water level monitoring system as example take the present invention, the predetermined condition of expression emergency comprise the water level value that is monitored object exceeded default alarm threshold value, with the communication disruption that is monitored object and monitor 131 faults etc. that are monitored object in order to supervision.
The data transmission and processing flow process from upper to the next below with reference to Fig. 6 and Fig. 7 detailed description.As previously mentioned, the data transmission and processing from upper to the next mainly refers to the process set according to the control command 310 that upper network 110 issues.
Fig. 6 shows the flow chart of the 3rd embodiment of the data transmission and processing from upper to the next.
As shown in Figure 6, receive in order to control command (S11) that the next side is set afterwards from upper network 110 at upper Department of Communication Force 121,122 pairs of received control command analyses of data processing division are identified corresponding with this control command object (S12) that is monitored, from storage part 124 read identify be monitored the attribute data, and determine concrete setting content (S13) based on this control command and the attribute data that reads.Subsequently, according to the information that is monitored object that identifies (for example, being monitored the type of object and numbering etc.) and determined setting content, this is monitored object sets accordingly (S14).
For above-mentioned assignment procedure from upper to the next, since the full detail (corresponding to management information) that is monitored object comprise with the next network 130 in be monitored the relevant data items of object (corresponding to status data) and be monitored the attribute data, therefore, when the control command that receives from upper network 110, need to determine setting content relate to be monitored the attribute data also relate to the next network 130 in be monitored the relevant data items of object, and set accordingly processing according to the setting content difference.
