Abstract

Constant pressure water supply in the power of intelligent control systems, adjustments to achieve through Mitsubishi Inverter speed pump to adjust the pump pressure and flow, in the day outside the peak hours in addition to water, other times are running at a very low frequency of state run.

I. System Overview:

1, constant pressure water supply control system for intelligent power-saving program 2 (optional):

System Architecture Description

a, constant pressure water supply in the power of intelligent control systems, adjustments to achieve through Mitsubishi Inverter speed pump to adjust the pump pressure and flow, in the day outside the peak hours in addition to water, other times are running at a very low the frequency of state, even in peak hours the water would not be run in 50Hz, so the energy can be substantial. At the same time, automatically by pumps, pump stop, rotation, automatic protection.

b, through the serial port UNO2050 read Inverter PID parameter settings, the current operating parameters and alarm, and through MODEM and the telephone network control center to the top;

c, after receipt of the police at the scene, the control center can remotely control UNO2050, for inverter control of the start and stop.

2, constant voltage power supply of intelligent control system 2 (optional):

a, and a different program, program 2 using, Adam5510KW-site data collection and control, and to support the remote control.

Second, the hardware structure:

1, I / O analysis:

DO: 1 Road, relay output, the inverter power supply is responsible for the on-off;

DI: 4 way, that is, alarm frequency, low water level alarm, high pressure alarm, low water pressure alarm. Signals are off.

2, controller compared Selection:

Option 1 and Option 2 is only the different parts in the controller, which is part of the program using a controller UNO2050, while Option 2 using Adam5510KW. Now, do the following:

a, Adam5510KW soft four-slot logic controller can be flexible to provide matching Advantech 5000 Series rich I / O modules, for example, matching four 5056 output of 16, you can 64 Road DO. In this way, we can be flexible to achieve a large number of local I / O of centralized control.

b, UNO2050 is the integration of generic controller, with 4 serial, in which two anti-high-voltage isolation, isolation board 8DO & 8DI, real-time operating system winCE.

c, we recommend the use of UNO2050, for the following reasons

- Adam5510KW for KJW Molded Case, UNO2050 is metal, so, UNO, compared to electromagnetic interference and better anti-KW;

- In this system, we have only five of the DIO, matching the 8DO & 8DI to 5055s, then the equipment should be the other three slots idle, idle rate of 92 percent, a little waste. If I choose to UNO2050, we use the onboard onboard isolation 8DO & 8DI, idle rate of only 56% have adequate room to expand, there is no waste.

- UNO2050 the Adam5510KW size is 1 / 2 weak, so more convenient to install;

- UNO2050 the use of low-power embedded CPU, real-time operating system winCE, stability;

- UNO2050 the use of solid-state electronic disk, a good earthquake.

Third, software Description:

1, the controller software for the preparation of:

Option 1, using UNO2050 integrated controller, the internal real-time operating system running winCE, we need to be embedded through the Microsoft.net platform programming: Serial Communication programming, read the data converter; onboard I / O control and acquisition program; transmitted serial data and I / O data to the central upper works.

Option 2, the logic controller Adam5510kw, KW-Software can be programmed to carry out the logic: the logic of serial communication program for the establishment, to read the data converter; I / O control and collection of logic programming; do a good job in the data converter and I / O channel mapping data for the center position works to read.

2, Center for Systems Engineering PC configuration:

Central Station can use the entire Chinese MCGS configuration software to collect data and control the purpose of the scene, the need to lower the corresponding channel, send commands to carry out data collection and decentralization. Start and stop the need for modem connections. Need to show a friendly configuration interface.
