Embodiment
In order to make those skilled in the art person better understand the utility model scheme; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, complete description; Obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all should belong to the scope of the utility model protection.
As shown in Figure 1; A kind of Internet of Things is adopted the control platform, comprises the central processing unit 6 of two serial ports, i.e. CPU; Data acquisition module, data transmission module 7, PLD 5, protocol conversion module, two serial ports of central processing unit 6 are connected with data acquisition module, data transmission module 7 respectively; Protocol conversion module is connected with central processing unit 6 through PLD 5.Protocol conversion module comprises: RS485 protocol module 1, MUDBUS protocol module 2, BACnet protocol module 3, LONworks protocol module 4; RS485 protocol module 1, MUDBUS protocol module 2, BACnet protocol module 3, LONworks protocol module 4 are connected respectively to FPGA module 5; Between connecting line be merely the transmitting-receiving two lines; FPGA module 5 connect with central processing unit 6 between be connected except that transmitting-receiving two lines data wire and address wire in addition.Central processing unit 6 is connected to data transmission module 7, is linked to each other by transmitting-receiving two lines, is to improve reliability, between need add protection and drive circuit.Data transmission module is ONU communication module or GPRS communication module or ZigBee communication module or WIFI wireless communication module or ethernet communication module.
Serial ports of the central processing unit of two serial ports connects data acquisition module, i.e. second line of a couplet circuit, and another serial ports connects the data transmission module, i.e. first line of a couplet circuit, the format conversion of first line of a couplet data and second line of a couplet data is accomplished in central processing unit.In second line of a couplet circuit, CPU is connected to PLD (FPGA), and FPGA is connected respectively to 4 protocol conversion modules, and the connection level is a Transistor-Transistor Logic level.Each protocol module all has level and protocol format separately, and protocol conversion module is accomplished the conversion of corresponding protocols level and Transistor-Transistor Logic level, and Data Format Transform is accomplished in central processing unit.Four kinds of protocol interfaces adopt time division multiplexing mode with communicating by letter of central processing unit, and central processing unit with which protocol module is communicated by letter in sometime, selects corresponding communication port by FPGA.In first line of a couplet circuit, CPU is directly connected to data transmission module, Transistor-Transistor Logic level.The communication module completion is adopted the control platform and is connected with the communication of central machine room.
Fig. 2 is the shape assumption diagram of the utility model; It comprises the accessory power outlet 8 of RS485 protocol module 1, the accessory power outlet 9 of MUDBUS protocol module 2, the accessory power outlet 10 of BACnet protocol module 3, the accessory power outlet 11 and the data communication module slot 12 of LONworks module 4, can insert ONU communication module, GPRS communication module, ZigBee communication module, WIFI wireless communication module, ethernet communication module respectively.The utility model can couple together the object of different agreement or system and central machine room, accomplishes data communication function, thereby sets up large-scale Internet of things system.
