The concrete communication process of the intelligence building system that the present invention provide is described in detail below.

1, point-to-point communication

Message Producer initiates once to communicate, after message consumer receives command frame to message consumer, it is judged that order It is the most legal to ask, and without mistake, then performs corresponding operating and returns normal response to message Producer.If function please Wrong appearance in asking, then return exception response.

Under this pattern, communicating pair all must have a unique address (1-255), for distinguishing other website, As shown in Figure 2.

When claim frame is downlink data upon handover, acknowledgement frame is sent completely at all claim frames and sends afterwards.

2, broadcast (multicast) mode communicates

One corresponding multiple message recipient of message promoter.Broadcast address is 0x00.

Message Producer initiates once to communicate, after message consumer receives command frame to multiple message consumers, it is judged that Command request is the most legal, without mistake, then performs corresponding operating and returns normal response to message Producer.If merit Wrong appearance in can request that, then return exception response, as shown in Figure 3.

3, typical case's Message processing flow process

1) address distribution: in CAN, all devices has unique MAC ID, span 1-255.This address is main Use when equipment configures, after system worked well, i.e. need not.Equipment connects as indicated at 4, and device address allocation flow is such as Shown in Fig. 5.

2) equipment configuration:

Physical object: in N-BUS system, all of entity module is all physical object, such as: PC, gateway, various mould Block.Object logic: various kinds of equipment that physical object is controlled or function are through abstract object.Such as: light, curtain, Service request etc..

After completing the configuration of all of equipment, whole system just completes the generation of object logic.At system worked well Time, system demonstration is not various modules to user, but object logic.Such as one system is by following object logic group Become:

Lighting circuit 1, lighting circuit 2, lighting circuit 3 ...

Curtain 1, curtain 2 ...

Exhaust fan 1

Air-conditioning 1, air-conditioning 2

Equipment configuration is completed by PC end configuration software, in configuration end software, and the module in each bus An all corresponding C language structure pre-defined, this structure embodies all properties of this module, as shown in Figure 6.

3) equipment controls

In bus any one equipment all can initiating equipment control command, such as PC, input module, opening and closing module. Below as a example by the input module connecting Self-resetting button, as shown in Figure 7.

4) facility information active upload

After object logic completes due to timed events or other spontaneous class actions, can believe to bus active upload state Breath, as shown in Figure 8.

The N-BUS Intelligent Building Control System of the present invention utilizes CAN to add self-defining application layer protocol, whole new definition A kind of standardization, extendible agreement, named N-BUS intelligent bus.N-BUS physical layer contain be integrated with CAN and 12VDC power line, contains 12V, GND, CANH, CANL.Use RJ45 interface Fast Installation.Application layer protocol be one for The custom-designed proprietary protocol of Intelligent Building Control System.

This bus had both remained the original advantage of CAN: real-time, reliability is high, capacity of resisting disturbance is strong, communication is fast Rate is high, easily realization and cost performance are high；The simultaneously the most self-defined application layer protocol being applicable to Intelligent Building Control System, complete Full object-oriented.

The design core of the Intelligent Building Control System agreement of the present invention is the concept proposing abstract object.So make Agreement is easier to understand, and greatly facilitates the exploitation of embedded software.

Physical object: in N-BUS system, all of entity module is all physical object, such as: PC, gateway, various mould Block.

Object logic: various kinds of equipment that physical object is controlled or function are through abstract object.Such as: light, Curtain, service request etc..

After completing the configuration of all of equipment, whole system just completes the generation of object logic.At system worked well Time, system demonstration is not various modules to user, but object logic.I.e. in Intelligent Building Control System, user is only Need to be concerned about the actual controlled object needing to control in real system, there is no the concept of module.For software engineer or secondary Object-oriented design method it is entirely for Developmental Engineer.Greatly reduce the difficulty of embedded software developing.

The course of normal operation of system, the process i.e. an object logic being controlled.Any one equipment in bus All can initiating equipment control command, such as PC, input module, opening and closing module.Below with a certain lighting loads (lighting loop 1), as a example by control process, the normal control process of system is illustrated:

The N-BUS Intelligent Building Control System Protocol Design of the present invention can be supported: security type information, service request class letter Breath, signal light control category information, curtain control category information, curtain controls category information, air-conditioning/floor heating controls category information, energy conservation Category information, video intercom category information, home wiring control category information.Plus reserved command word, it is to prop up holding equipment kind in the market The Intelligent Building Control System agreement that class is most.Therefore, N-BUS Intelligent Building Control System agreement applicable situation is widely: Go for the application scenarios such as intelligent hotel guestroom control, intelligent lighting, Smart Home.And in traditional sense, intelligent hotel Guest room control system, intelligent illuminating system, intelligent domestic system be three separate, distinguish the biggest product line.N-BUS Intelligent Building Control System is under unified standardized bus protocol infrastructure, it is provided that the most compatible product line.

The address administration mode of the N-BUS intelligent building management system protocol of the present invention uses distributes address mode automatically. These are different from traditional fieldbus working method, more flexibly, conveniently.

The N-BUS Intelligent Building Control System agreement of the present invention supports IAP order, can complete compiling in application of module Journey.IAP is the acronym of In Application Programming, and IAP is that the program of user oneself is at running In the subregion of User Flash is carried out programming in order to firmware upgrade can be realized easily after product is issued Function.IAP is a general concept, but it realizes process, by the difference of chip, the difference of development environment, development language Different and different.In native system, it is simply that based on CAN, it is achieved the IAP function of module.Flow process such as Figure 10 and 11 that IAP realizes Shown in.N-BUS Intelligent Building Control System Protocol Design is reserved with nearly 20 kind equipment command words, can expansion equipment/module at any time, Compatibility, extensibility are the strongest.Many bags format design of N-BUS Intelligent Building Control System agreement well compensate for CAN The short shortcoming packing formula of bus.

Although the present invention discloses as above with preferred embodiment, so it is not limited to the present invention, any this area skill Art personnel, without departing from the spirit and scope of the present invention, when making a little amendment and perfect, the therefore protection model of the present invention Enclose when with being as the criterion that claims are defined.
