Hot projects supporting IC card time charge device

I. Introduction: Copper timing IC card water control is integrated water solenoid valve controller + copper + power as a whole, the new structure, safe and reliable multi-user smart meter. This product uses the IC card pre deductions way through microelectronic control solenoid valve, to achieve reading cartoon water, according to the timing of deductions of water management. A table to support multi-card, and the limited number of cards. Student apartment hot water, hot water factory dormitory, public bathrooms with hot charges and energy conservation, water conservation, water recycling equipment investment in an effective way. Water control structure to take the whole sealed design, can be installed in the vicinity of the bathroom, in order to facilitate the discharge card and take the card user. Water control installation is simple, as with ordinary water meter installation, only with a need for additional DC12V DC power supply which can work. Very safe and reliable. IC card charge management system can and other schools share a IC card, the management fees, "Card" Second, the technical characteristics: 1, the controller sensor module selects the original "Philips" chip. 2, high-quality patents solenoid valve, low power consumption, low failure rate, long service life switching frequency of more than 10 million times, easy maintenance. 3, maintenance-free power supply design using unique technology off valve design can be achieved without battery backup power off valves, low-power microprocessor, a powerful, high reliability and anti-jamming capability. 4, liquid crystal display (digital display can also be used), fully sealed design, with timing accuracy, safety and reliability, long life and water features. 5, external integration with nice full copper shell design and a unique place card device design features, the use of more humane. 6, a multi-card, to achieve the purpose of an independent apartment hostel than water. Unique encryption method, can completely eliminate the illegal card invasion. 7, consumption patterns design:. A, continuity of timer chargeback mode b, small prepaid mode c, custom mode e day limit deductions timing mode 8, easy to use, effective IC card into the solenoid valve is opened , take the card or power failure, the solenoid valve closes automatically. Deductions in accordance with the use of water. Third, the main technical parameters: Project Parameters reader module storage capacity of 2M bits Philips RC500 reader time timer <200ms Power DC 12V ± 15% Current Standby (solenoid valve is not activated) <100mA Work (electromagnetic valve action) <1000mA electrical solenoid valve parameters Rated voltage: DC 12V; Working temperature: 0 ℃ -50 ℃ Humidity: 20% -95% RH Dimensions (externally mounted) 165mm × 95mm × 105mm solenoid valve solenoid valve main performance parameters Performance parameters rated voltage DC12V coil resistance 28Ω ± 4Ω (20 ℃ when) switch type AC continuous type operating pressure 0.02Mpa-0.8Mpa Medium temperature 1 ℃ -100 ℃ (according to user needs to set) Response time on ≤0.15s off ≤0.5s life ≥15 thousand times
