Embodiment

[0130] Step 1. First determine that the text to be displayed on the water column sprayed by the electromagnetic water valve 6 is "West", connect all the negative pins of the diode 7 in parallel and connect them to the driver 10, and each negative pin leads out a line, which is defined in turn as y1, y2, y3, y4...y16, connect one line of all electromagnetic water valves 6 not connected to the diode 7 in parallel and then connect it to the driver 10, and lead out their respective line ends, which are defined as x1, x2, x3, x4... x16;

[0131] Step 2: Define the 9 digital I / O ports {22, 24, 26, 28, 30, 32, 34, 36, 38, 40, 42, 44, 46, 48, 50, 52} as a one-dimensional array pinx[ 16], control the total 16 signal input ports of the four drivers L298N, the total 16 signal output ports of the four drivers L298N are connected to the 16 lines of x1, x2, x3...x15, x16 of the electromagnetic water valve, and define the single chip microcomputer 9 The digital I / O port {23, 25, 27, 29, 31,...

Abstract

The invention discloses a digital water curtain wiring system which comprises a lower water tank and an upper water tank. The lower water tank is connected with the upper water tank by a water pipe, electromagnetic water valves are arranged in the upper water tank and are arrayed according to a horizontal matrix form, a diode is serially connected onto each electromagnetic water valve, a wire of each electromagnetic water valve is connected with an anode pin of the corresponding diode, a cathode pin of each diode is close to an edge of the corresponding electromagnetic water valve, the cathode pins of all the diodes are connected with one another in parallel and then are connected with a driver, other wires of the electromagnetic water valves are connected with one another in parallel and then are connected with the driver, two sensors are arranged on a side of the upper water tank along the vertical direction, water level information of the upper water tank can be acquired by the two sensors, the two sensors are connected with a water pump by signal wires, the water pump is arranged in the lower water tank, the upper water tank is further connected with a control system, the control system comprises a single chip microcomputer, and the driver can drive a switching power supply of each electromagnetic water valve under the control of the single chip microcomputer. The digital water curtain wiring system has the advantage that problems of complexity in control and high cost due to various wires of digital water curtains in the prior art can be solved by the aid of the digital water curtain wiring system.

Description

technical field [0001] The invention belongs to the technical field of digital water curtain display, and in particular relates to a digital water curtain wiring system, and also relates to a control method of the digital water curtain wiring system. Background technique [0002] Digital water curtain (or digital water curtain, digital water wall, waterfall printer, digital waterfall, etc.) originated from an interactive building displayed by the Massachusetts Institute of Technology at the 2008 World Expo in Zaragoza, Spain - "Digital Water The walls and roof of the "Water Pavilion" are digitally controlled water curtains, which can display images and text according to preset programs. After several years of development, foreign digital water curtains can display fine text, patterns, etc., and have two expression methods of yin and yang, which can be human-computer interaction, touch and handwriting input, and can realize the perfect combination of water curtain, light and ...
