Face.There are many agreements at this time to connecting, how to be compatible with the problem of these equipment are as urgent need to resolve more with open arms.
Utility model content
The utility model provides a kind of small-sized RS485 converter, solves how to be compatible with different manufacturers, no in the prior art
The technical issues of with equipment interconnection.
The purpose of this utility model is achieved through the following technical solutions:
A kind of small-sized RS485 converter, comprising: microprocessor, power circuit, the first serial line interface, the second serial line interface,
Control panel and memory, the microprocessor respectively with the first serial line interface, the second serial line interface, control panel, memory
Connection, the power circuit give the first serial line interface, the second serial line interface, microprocessor, memory power supply respectively.
The technical effect of the utility model are as follows:
The docking conversion between different agreement is provided, non intelligent type smart home device can be accessed into Intelligent housing
System solves the problems, such as that protocol-compliant present in smart home system docks.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Needed in attached drawing be briefly described, it should be apparent that, the accompanying drawings in the following description is only the utility model
Some embodiments for those of ordinary skill in the art without any creative labor, can also be according to this
A little attached drawings obtain other attached drawings.
Fig. 1 is the structural schematic diagram of the utility model embodiment.
Specific embodiment
To keep the above objects, features, and advantages of the utility model more obvious and easy to understand, with reference to the accompanying drawing and have
Body embodiment is described in further detail the utility model.
As shown in Figure 1, being a kind of small-sized RS485 converter provided by the embodiment of the utility model, comprising: microprocessor,
Power circuit, the first serial line interface, the second serial line interface, control panel and memory, the microprocessor are gone here and there with first respectively
Line interface, the second serial line interface, control panel, memory connection, the power circuit give the first serial line interface, the second string respectively
Line interface, microprocessor, memory power supply.
Wherein, first serial line interface and second serial line interface include RS485 protocol conversion chip and periphery electricity
Road.
In order to support to realize the protocol conversion of RS485 to ZigBee based on ZigBee smart home device, further include
ZigBee transceiver, the ZigBee transceiver are connect with the microprocessor.
In order to support the smart home device based on bluetooth, realize that RS485 further includes bluetooth mould to the protocol conversion of bluetooth
Block, the bluetooth module are connect with the microprocessor.
The first serial line interface in Fig. 1 includes the peripheral hardware devices such as RS485 protocol conversion chip, the first serial line interface master
If receiving the RS485 instruction that periphery need to convert, which is transmitted to microprocessor.Second serial line interface also includes RS485 association
The hardware devices such as conversion chip are discussed, which plays switching host computer configuration information to microprocessor, and sends micro- place
Manage the instruction of the specified output of device.Microprocessor is the core of entire converter, not only receives configuration information, is saved by memory
Configuration information also receives the RS485 instruction that the transmission of the first serial line interface comes, identifies to instruction, it is determined whether can match and deposit
The configuration information that reservoir saves.If matching the configuration information saved, corresponding instruction is exported further according to configuration information, goes control intelligence
Relevant device in energy house system.In addition, the control instruction of different brands equipment can be stored in advance in depositing in the utility model
It in reservoir, can be configured by control panel, such as the lamp dimmer of the switch panel of A brand and B brand is carried out
With association, allow to control the lamp dimmer of B brand by the switch panel of A brand.
It is that the RS485 that microprocessor can identify is instructed that second serial line interface, which receives, is configured to microprocessor by host computer
The inside, storage are saved.Up to 100, identification content is every instruction for the RS485 instruction that microprocessor can be saved and be identified
Length, every instruction content, it is necessary to it is completely the same, microprocessor just judge to think the instruction as effective instruction, just control
Export corresponding control instruction.The received instruction of each can correspond to 5 output orders, can be with 5 kinds of differences of linkage control
Equipment.Its 5 instruction for corresponding to output can be configured to inside microprocessor by host computer configuration software.Microprocessor
Configuration information is saved, according to the instruction of input to determine whether what instruction output order, export.Such as: an output RS485
The switch panel of instruction, on and off instruction are respectively 11 22 and 11 33, and lamp dimmer controls the instruction point of LED light on and off
Not Wei 55 11 22 33 44 and 55 11 22 33 45, at this time switch panel can not directly control lamp dimmer go control lamp
On and off.First serial line interface of the utility model is connected to switch panel, the second serial line interface is connected to lamp dimmer, leads to
It crosses host computer configuration software to be mapped the instruction 55 11 22 33 44 of opening for opening instruction 1122 and controller of panel, pass refers to
Enable 11 33 and the pass instruction of controller 55 11 22 33 45 be mapped.Then it downloads to inside CPU and is deposited by memory
Storage.After equipment operation, opening for switch panel is pressed, switch panel exports 11 22, RS485-2 and receives the signal, is transferred to
CPU, CPU, which retrieve storage the inside, matching instruction, and corresponding output 55 11 22 33 44, the first serial line interface should
Instruction is transferred to lamp dimmer, and lamp dimmer receives out instruction, i.e. control LED light is opened.
The technical effect of the utility model are as follows:
The docking conversion between different agreement is provided, non intelligent type smart home device can be accessed into Intelligent housing
System solves the problems, such as that protocol-compliant present in smart home system docks.
It is understood that the restriction of the not structure paired systems of system structure shown in figure, may include than illustrating more
More or less equipment perhaps combines certain equipment or different deployed with devices.
More than, only specific embodiment of the present utility model, but protection scope of the utility model is not limited thereto,
Anyone skilled in the art within the technical scope disclosed by the utility model, can readily occur in variation or replace
It changes, should be covered within the scope of the utility model.Therefore, the protection scope of the utility model should be with claim
