Accompanying drawing 3 is a kind of Multifunctional main board structural representations of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Embodiment:
The technical solution of the utility model is: a kind of LonWorks equipment development technique teaching experiment porch, is made up of experimental box, Multifunctional main board, core cpu plate, LON network interface card, computer supervisory control system.
Ginseng Fig. 1, experimental box is the carrier of this experiment porch, Multifunctional main board is arranged in experimental box, Multifunctional main board devises the multiple IO style interface application of multiple I/O cell object module for core cpu plate, Multifunctional main board is reserved with the connection of core board interface for I/O object module and core cpu plate, core board is reserved with communication interface for being connected with LON network interface card, computer supervisory control system realizes the communication with core cpu plate by LON network interface card, and core cpu plate realizes the observing and controlling to each I/O cell module by moving calculation machine monitoring program.
Ginseng Fig. 2, Multifunctional main board includes D/A, A/D, eight logical point equal the abundant I/O cell module such as input, eight logic level displays, audio driven, Control, clock, temperature survey, signal light control, LED display, core board interfaces.The connection of core board interface and core cpu plate adopts connector to design, dismounting to core board when facilitating programming program, be connected by wire jumper interface between core board interface with I/O cell object module, this can make the I/O programming pin of core board be defined as several working ways, the convenient experimental study to core board I/O programming pin.In addition Multifunctional main board further comprises direct supply, regulated power supply, the pulse power, the first-class kinds of experiments power supply of digital display meter and measure display module, facilitating experimental observation.
Ginseng Fig. 3, core board contains FT3150 free topology smart transceiver, eeprom memory, 10MHZ crystal oscillator and FT-X1 communications transformer 4 critical pieces.Wherein FT-X1 communications transformer is for connecting LON network interface card and FT-3150 free topology smart transceiver, FT-3150 free topology smart transceiver is connected with the I/O cell module on Multifunctional main board by 11 pins (IO0 ~ IO10), during programming development, according to different I/O cell object modules, these 11 I/O pin flexible configuration can be become several working ways, thus realize the study to LonWorks equipment development technology.
For " PWM exports and controls light experiment ", implementation process is described below.
Referring to Fig. 2, control object is light control unit, IO0 programming is defined as pulsewidth object output by computer supervisory control system, IO7 is defined as an input object, connect IO0 on core board interface and signal light control " IN " port with wire jumper, IO7 port connects the flat input of eight logical point " DO0 " port.Computer supervisory control system is downloaded in core board by LON network interface card and runs.When button is pressed, pulsewidth output duty cycle is increased to 100% automatically by 0%, and bulb is slowly lighted, and when button is upspring, pulsewidth output duty cycle is decremented to 0% automatically by 100%, and bulb slowly extinguishes; Closer, also can define other port (as IO1) for pulsewidth object output, at this moment only need the IO1 port be connected to by the wire jumper of signal light control " IN " port on core board interface.Therefore the exploitation and the study that FT-3150 free topology smart transceiver pulsewidth are exported to I/O object programming mode can conveniently be carried out.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
