Embodiment
Below with reference to accompanying drawing, the utility model is described in detail, should be appreciated that specific embodiment described herein only for explaining the utility model, and be not used in restriction the utility model.
As shown in Figure 1: the control panel of the present embodiment, the MCU micro-control unit 1 connected successively is comprised, communication unit 2, coupling isolated location 3, Power Management Unit 4, and the key-press input unit 5 be connected with described MCU micro-control unit 1, the fieldbus 10 be connected with described coupling isolated location 3.
Described key-press input unit 5, for gathering the input signal of active user.
Described MCU micro-control unit 1, for receiving the input signal of key-press input unit 5, and carries out information interaction with described communication unit 2, the transmission at the scene in bus 10 of the setting of completion system functional parameter and key-press input signal.Concrete, 6 general purpose I/O port of MCU micro-control unit 1 are as the signals collecting port of 6 buttons in intelligent control panel, and after the energising of control panel functional circuit, MCU micro-control unit 1 is with 100ms cycle timing acquiring push button signalling input port state.Being that high level then represents that button is down state when collecting port signal, is that low level then represents that button is release conditions when collecting port signal.MCU micro-control unit 1 carries out protocol data alternately by spi bus and communication unit 2, and the data of intelligent control panel are carried out alternating transmission by fieldbus 10 communication interface.
Described communication unit 2, for the treatment of on-scene communication bus signals, carries out the two-way interactive of functional parameter with MCU micro-control unit 1.In the present embodiment, communication unit 2 adopts Pyxos FT communication unit 2, and it is supported on a pair 2 core twisted-pair feeders and transmits 24VAC/DC power supply, and signal of communication and power nonpolarity, transfer rate is up to 312.5Kbps.Pyxos FT communication unit 2 specifically comprises: communication protocol processing unit 21 and fieldbus networks Transmit-Receive Unit 22; Described communication protocol processing unit 21, for carrying out protocol data alternately with MCU micro-control unit 1, is transmitted the communications data frame of described intelligent control panel by high-speed field bus 10.Described fieldbus networks Transmit-Receive Unit 22 is connected with described coupling isolated location 3, forms the current supply circuit be made up of fieldbus networks Transmit-Receive Unit 22, coupling isolated location 3, Power Management Unit 4 and MCU micro-control unit 1.
Described coupling isolated location 3, for separating of the power supply signal in fieldbus 10 and signal of communication; Due to not only transmit communications signals but also transmit 24V power supply signal in existing Pyxos bus, therefore need signal of communication to be separated with power supply signal.Because Pyxos data signal bus is high-frequency carrier signal, the signal of communication in Pyxos bus is separated with 24VDC/AC power supply signal by common mode inductance by the isolated location 3 that is coupled in the present embodiment.
