The method includes: step one, using a device communication module to read device signals of different security monitoring devices, analyzing, recognizing, setting up system signals, and sending the system signals to a signal analyzer; step two, using the signal analyzer to analyze the system signals, setting up device signal targets, and sending the device signal targets to a linkage strategy processor; step three, if the linkage strategy processor finds associated linkage strategies, sending device signal change signals to a model storage access module and a superior security monitoring integrated platform, and if not, directly performing the step four; step four, enabling the linkage strategy processor to sequentially execute each predefined responding strategy to form device commands, and sending the device commands to an order processor; and step five, allowing the order processor to code the device commands to form instructions, and sending the instructions to the device communication module which sends the instructions to a target device. Using the method for responding to signals from the security monitoring subsystem lowers the technical difficulty and reduces the workload of development of the integrated platform of a security system.
Description
(1), technical field: the present invention relates to a kind of data processing method, particularly relate to a kind of response from the method for safety monitoring subsystem signals.
(2), background technology: at present, different safety monitoring subsystems integrated do not have a kind of unified standard, still in a kind of opening and exclusive two kinds of states that intergration model mixes.The integrating process of general security device system mainly comprises:
1. according to the interface protocol of specific security device subsystem, create a slave computer communication system that can receive identification equipment subsystem signals and carry out the collection (preposition communication subsystem) of data;
2. communication subsystem is resolved the signal of receiving according to specific coding protocol, concurrent toward host computer (integrated platform);
3. integrated platform is responsible for service equipment model and linkage strategy, responds the signal from communication subsystem, and response coding is mail to communication subsystem.
Said process is independently realized by several different software modules conventionally.At the security device for different, carry out when integrated, all need to specifically encoding for different access protocols, realize technology more complicated.
Because security device industry lacks unified industry standard, there is larger difference in the implementation of the interface protocol that therefore security device externally provides, mainly comprise interface specification based on OPC, based on serial ports as the programming of RS485 agreement, and the network insertion pattern based on ICP/IP protocol etc.When prior art accesses each security device subsystem, conventionally all need to use C++ or Java etc. to carry out protocol interaction processing, analyze the device signal that decoding receives, according to the rendezvous protocol with integrated platform, decoded signal is sent to platform, and platform completes all processing procedures of receiving after signal.
As shown in Figure 1, the Integrated Solution of existing security device system is generally divided into two independent parts that realize, first by devices communicating subsystem 100, be responsible for the communication connection of foundation and specific security device subsystem, be responsible for receiving the device signal of transmitting from device systems; Then utilize the link passage between devices communicating subsystem 100 and safety monitoring integrated platform 101, signal is converted to after the bytes of stream data that server end can receive, send to safety monitoring integrated platform 101, safety monitoring integrated platform 101 is received after request, retrieve the linkage strategy of this request, according to predetermined linkage protocol, make response; And the order that the equipment that is encoded to can be identified mails to devices communicating subsystem 100, by devices communicating subsystem 100, be responsible for mailing to particular device, driving arrangement work; Or as the signal receiving belongs to equipment state signal, upgrade system model, the state and the device systems that maintain equipment keep synchronous.
Because the Integrated Solution of existing security device system is all will carry out independent protocal analysis decoding and coding for the agreement of every kind of equipment in application program, realization is during to different security protection subsystems integrated, its coding work amount is larger, and the development requires developer of this communication system has stronger signal processing, the program capability of the distributed and high technology such as concurrent, while is for the reliability of system, expandability and maintainability require high, in addition, the debugging of security protection subsystem is owing to lacking analogue means, therefore its debug process is very difficult on stream.
In the Integrated Solution of existing security device system, have and adopt XML language to solve the unified problem of describing of signal in integrated system as the mechanism of description, but because traditional XML technology only can realize unified description of grammer for structure, and shortage is for the semantic description of model, therefore, cannot be used for as a kind of conforming open descriptive tool the integration field of safety monitoring.The body of rising in recent years (Ontology) technology, standardization by the concept to specific area, term and mutual relationship thereof is described, sketch out ABC system and the descriptive language in this field, as a kind of explanation mechanism, body has been strengthened knowledge sharing and has been reused by different application.But, have not yet to see during integrated and signal that ontology is applied to safety monitoring integration field equipment processes.
