Embodiment
Below by specific embodiment technical solution of the present invention is described further.
The invention, support the wireless urban lighting monitoring technique of multichannel, multi-protocols, with different communication modes, as communication interfaces such as RS232, networks different channels is set, and every kind of communication protocol is packaged into a protocol library, when illumination wireless Surveillance center station software is controlled the illumination monitoring terminal of supporting this agreement, enables the data of this protocol library, resolve accordingly, the channel of data by correspondence sent or receive data from corresponding channel.
The realization of multi-protocols: adopt the mode of data dictionary to manage all parameters and data item, the core data item in the agreement that can compatible come in must have definition in data dictionary, and in simple terms, data dictionary is exactly complete or collected works, and each agreement all is its subclass.Concerning application layer, one group of abstract data (its entity content must have definition in data dictionary) only is concerned about in the transmitting-receiving of its data, and be indifferent to its concrete definition and performance in a certain agreement, thereby application layer has been shielded the details of agreement effectively, and making application layer needn't frequently be that the increase of agreement is constantly revised.
This programme adopts succession and the polymorphic characteristic in the object oriented language to design realization, with all protocols abstract is an abstract description TRLPrtl, each concrete agreement is all inherited (T204Prtl from this abstract class, T205Prtl ...), its upper strata is to the statement of quoting that only need provide the TRLPrtl object of quoting of protocol object, keep supplying the unified processing of layer different agreement object, thereby avoided direct correlation concrete agreement.As shown in Figure 1, be the schematic diagram of realization of the multi-protocols of the embodiment of the invention.
