Description
Technical field
The utility model relates to water-saving control device, in particular, and a kind of novel water regulator.
Background technology
Water saving has special important meaning to us; Enhancing along with people's consciousness of saving water, various water saving measures and water saving fixtures arise at the historic moment, water control owner will be by electronic control module, three parts of IC-card and sender base table form, electronic control module is the core of water control machine, be responsible for the control of the unit such as sampling, charging, demonstration of water control machine, for the running status of water control machine, take appropriate measures in time and process simultaneously, then the significant data of operation all will be preserved for use and analyze later; IC-card sheet has been the carrier of the exchanges data between water meter Dao Guan water department computer.Sender base table is generally by standard machinery table and adds that tongue tube sensor and electric machine valve form.
Fig. 1 is existing water control machine mode of operation: IC-card arranges after discharge through PC office terminal parameter and uses, IC-card is inserted into and on RF antenna, reads data in card, being transferred to Intelligent control board processes, receive that infrared sensing switch red-emitting runs into the signal that barrier reflects, Intelligent control board drives the valve working water outlet of solenoid valve, and water flow drives flowmeter rotor to rotate and produces pulse signal transmission Intelligent control board data processing; The amount of money/water consumption after processing is shown and held Igor Kanygin volume by be allowed user's support in time by charactron.By IC-card reading out data, be sent to again the processing such as the consumption data inquiry of PC office terminal, statistics, form, clearing; Reporting the loss/remove blacklist all needs PC office terminal to process to be transferred to water control machine by IC-card to carry out and report the loss/remove blacklist, and the clock adjustment of control panel also needs to calibrate by capture card.
There is following problem in it: user's situation that in use careless IC-card has fallen or forgotten, the thing administrative office that makes a trip reports the loss for this reason, user comes fallback consume one's strength and lose time, also there will be and report the loss difficult situation, be exactly administrative office come off duty (changing shifts) user can not be reported the loss in time cause Igor Kanygin volume to be used by other people;
IC capture card is generally used in the data acquisition of off line type water control machine, need keeper to go every water control machine image data in the specific time, the workload of picture large enterprises dress 500 water control machine collections is large, and each dormitory door is locking, increased the time of the door of unblanking, the situation (data are incomplete) of omission is grown and had to the running time; The data that possible accidents happened to situation collects are not given in time PC end processing IC capture card and lose, and can not grasp in time latest data and repeat above-mentioned work; Keeper, when processing blacklist, also needs to take card to go to eliminate working method similar with acquisition mode; The clock adjustment of water control machine also needs to calibrate by capture card; Wired interconnection type water control machine, large in wiring installation, the relative off line type of cost is high, is difficult to universal water-saving meaning.
Therefore, there is defect in prior art, needs to improve.
