I. Overview 
 With the development of the times and advances in technology, people increasingly high demand for the fountain effect, which prompted the fountain control technology to constantly update and improve, the performance increase of scientific and technological content, as well as the diversification of forms of control, such as program control, sound control run Quan and so on. The control system is used for a dedicated digital sprinkler control system, due to extensive use of the microcomputer and other high-tech means, to build a digital control program operating platform, the computer controller programming. So that the product is very powerful, and the operation is extremely easy to learn, so that users can be programmed at any time on the new track, so that the fountain often look new features are as follows: According to the control systems of different sizes, different functions can be composed of all the needs can be found in scene programming based on the actual effect of water type, in computer programming and demonstration, until satisfied, then the program is downloaded to the controller, run-time controller can be run offline (not associated computer); This is undoubtedly the fountain manufacturer or the final The user provides the greatest convenience, all of your water effect control scheme can be realized in the controller. This controller to break through the conventional PLC control restrictions to avoid complex programming aspects of the user which can be programmed in the understanding of programming principles. 
 Second, digital nozzle controller system consists of: 
 Type: XHSM-56A1 
 Digital nozzle controller host 
 Type: XHSM-16EM 
 Controller 16 expansion module (controlled 16 
 One-dimensional nozzle, or 8-way two-dimensional nozzle) 
 Model: EI-8I 
 Enter the drive module 
 (8-way zero signal input) 
 Model: CP-8T 
 Output drive module 
 (Control drive pulse / direction) 
 Computer editing software 
 1, modular, modular design, easy expansion 
 The control system is divided into two parts: digital nozzle control the host XHSM-56A1 24-point input (32-point output), and the bus expansion module unit (can be divided into 16 XHSM-16EM 8 Road XHSM-8EM 4 Road XHSM-4EM to be improved "), expandable up to 500 channels. It is mainly the following functions: 
 1) pattern selection. Set different parameters can be combined dozens of standard pattern. 
 2) the swing speed is stable, set the time is accurate. 
 3) an external input terminal stop / start control function 
 4) 
 2, advanced technology, reliable performance 
 The system uses a contemporary state-of-the-art ARM technology, complex control functions integrated in one, simple interface and expansion interface, ease of maintenance, high reliability and significantly reduce operating and maintenance costs. Far more than the anti-jamming capability of the 89 series of microcontrollers. 

 3, simple operation, with a load capacity 
 Write a program of this system is different from the Mitsubishi or PLC products do not need to have the computer expertise, and only under the control requirements, select the appropriate working methods and enter the time, control the angle and speed control parameters, we can achieve a variety of shape changes in the portfolio . The company develops digital head control software stored in the PC programming and watch the demonstration effect can download directly to Digital nozzle controller, based on the file when you save to the SD card; water user for debugging type and track simple backup, even if the control system is completely destroyed, as long as the control file can quickly restore to restore the system. Because of its scalability, breaking the restrictions on the number of load greater changes in the portfolio space for the engineering design of the fountain system. 
 Supporting dedicated digital head control software (for free), allowing the user a simple and convenient water design and testing; multiple water-in instance to call or refer to the same time can be saved in the computer.
