11. The card reading display part is installed separately from the valve meter, which is convenient for the user to insert the card and check the balance.
12. Complete safety measures, which can record the number of various illegal attacks, and lock the valve if necessary, such as opening the shell, using strong magnetic interference, disconnecting the flowmeter, inserting an illegal card, leaking, etc.
13. Both the POS machine and the valve are supplied with a safe voltage and use a dedicated power supply. The voltage at the water supply site is 12V, so there is no electric shock hazard.
Topology diagram of water control system
(1) The main body of the system
1. Microcomputer.
The built-in “Golden Dragon Card Water Control System” software is used for parameter management of the water control system; card information management; various report management; operator information management; database management, etc.
2. Water controller.
The main function of the water controller is to control whether to supply water and billing during the water supply period. Specifically, it reads and verifies card information; displays working status and information; is responsible for communication with intelligent cascade devices and systems; manages and controls execution devices; stores and memorizes water transaction information; water controller and system communication adopt RS-485 communication . The water controller adopts anti-drain and splash-proof design as a whole. The water controller adopts isolated DC low-voltage power supply to ensure safe use.
The water controller can only read one type of card, and the water controller model should be selected according to the type of card used by the user.
The timing type water controller is charged according to the time of opening the valve to supply water, and the meter type water controller is charged according to the amount of water flowing through. The cost of the timing water controller is lower than that of the metering type, and the billing accuracy is relatively low.
3. Universal charge card reader.
The main function of the universal charge card reader is to read and verify card information for registration, inquiries, and purchase of water charges.
There are different models of universal charge card readers, corresponding to different card types. The card type used should be the same as that of the water controller.
4. The first-level management machine.
The main function of the first-level management machine is to transfer data, working status, and work instructions of the water control system, and to exchange data with the computer; and to transfer data to the second-level management machine. RS-232 serial communication is used for communication with computer; RS-485 communication is used for intelligent cascade or secondary management machine.
When the number of system water controllers is less than 100, it can be directly driven by the first-level management machine, and the second-level management machine is not used.
5. Secondary management machine.
The main function of the secondary management machine is to adopt a hierarchical structure to solve the contradiction between RS-485 machine quantity and response speed. The second-level management machine can perform water control system data transfer, working status transfer, work instruction transfer, water-controller communication management, and data exchange with the first-level management machine. RS-485 serial communication is used with the first-level management machine; RS-485 communication is also used with the intelligent cascade device.
When the number of water controllers is greater than 100, a second-level management machine is added, and the second-level management machine adopts a dial switch to set the management machine number. The number ranges from 01 to 60, and the secondary management machine in a system must not have duplicate numbers.
6. Intelligent cascade device.
The main function of the intelligent cascade is to isolate the communication, improve the communication load capacity, determine the working status of the communication line, and provide a low-voltage safe DC power supply for the water controller. The communication input and communication output of the intelligent cascade are RS-485, the power input of the cascade is AC220V, and the output is DC12V2A isolated DC.
7. Four-way transfer box.
The main function of the four-way adapter box is to connect the communication line of the system and the water controller to ensure the long-term stability of the wiring head. Generally, the water controller works in harsh environments (high temperature, high humidity, splashing), so the four-way junction box has a waterproof design.
8. Number card.
The function of the number card is to set a specific number for the water controller for the system to distinguish and manage. The “+, -” number card can adjust the opening amount of the valve, so as to control the size of the water flow, so that the different water outlets are as balanced as possible. The number card is composed of 12 cards from 1, 2, 3 to 9, 0, +, -.
The type of the number card should be the same as the type of card used by the water controller.
When the water controller is locked, using the number card will not change the machine number, but can be unlocked. The machine number can be changed after unlocking.
Note: The EM card water controller uses the photoelectric number card to set the number.
9. Base table
The base meter currently used is an integrated water meter with a valve. The main function is to measure the flow of water flowing through; visually display and transform the flow signal into an electrical signal through a signaling device to provide intelligent remote measurement and control; close or open the valve through the actuator to achieve the ultimate goal of controlling the flow of the pipeline. The control signal of the valve is provided by the water controller.
10. Valve
The main function of the valve is to control the on and off of the water flow to achieve the purpose of billing and water cut without money. When the pressure of the pipeline does not change or the pressure does not change much, the water flowing through the pipeline is proportional to the water passing time. The purpose of controlling billing is achieved by controlling the time of opening and closing the valve. The control signal of the valve is provided by the water controller, and the valve is driven by the motor deceleration mechanism.
