Embodiment

Below in conjunction with drawings and Examples, embodiment of the present utility model is described in further detail.Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.

A kind of digital cascade device of the utility model comprises communication unit, main control unit, solenoid control unit and a plurality of solenoid valve as shown in Figure 1.Communication unit is used to receive literal or the graph data that needs show; Main control unit is connected with described communication unit, is used for described literal or graph data are sent to the solenoid control unit by serial ports; The solenoid control unit is connected with described main control unit, is used for according to the literal or the graph data that receive, the switch of control electromagnetic valve; Each solenoid valve is by controlling the length of water column switching time.

The solenoid control unit comprises string and conversion subelement and Darlington transistor array chip.The serial data that string and conversion subelement are used for receiving from main control unit is converted to parallel data; The control end of Darlington transistor array chip is connected with the parallel port of described string and conversion subelement, and the output terminal of each Darlington transistor is connected with a solenoid valve respectively, is used for the parallel data according to described string and the output of conversion subelement, controls described a plurality of solenoid valve.

Communication unit uses the RS485 interface, according to predefined communication unit address, carries out the cascade of a plurality of digital cascade devices.Wherein, adopt toggle switch to set the communication unit address.

The circuit theory diagrams of main control unit of the present utility model as shown in Figure 2, it is the chip of ATmega168 that the main control chip of the main control unit in the present embodiment adopts model, this main control unit further comprises: main control chip, for the total system circuit provides correct sequential, guarantee the operate as normal of circuit system; The jtag interface submodule is used for the debugging and the download of program; The resetting sub module is used to realize the normal electrification reset of total system.

The circuit theory diagrams of communication unit of the present utility model as shown in Figure 3, communication unit in the present embodiment uses the RS485 interface, act on serial communication protocol, it is the chip of MAX487EPCA that present embodiment adopts model, link to each other with the respective pin of main control chip in the main control unit, can carry out multi-computer communication, therefore different module's addresss can be set, carry out the cascade of a plurality of digital cascade devices, be used for showing more contents.Address setting uses toggle switch, and toggle switch is connected with the respective pin of the main control chip of main control unit, and main control chip is finished obtaining of address by each state of detection toggle switch.

The circuit theory diagrams of solenoid control of the present utility model unit as shown in Figure 4, the main control chip of the solenoid control unit in the present embodiment uses 4 74HC595D chips of serial line interface control, realize string and conversion, because each 74HC595D chip comprises 8 parallel port, so can produce 32 parallel interfaces.These parallel port link to each other with the control corresponding pin of Darlington transistor array chip ULN2003 respectively, and 32 control signals of Darlington transistor output can be controlled 32 solenoid valves.These 32 solenoid valves are " one " word and arrange, and each solenoid valve is in requisition for a literal that shows or a point of figure.Main control unit is accurately controlled the opening and closing time of each point, and then the length of control water column, and this a series of water column different in size has formed literal or figure in the process that falls.
