Abstract

The utility model discloses a random cipher consumable verification device on a water purification machine. The device comprises a switch panel, a singlechip controller, a low-voltage switch, a booster pump, a pressure gauge, a reverse osmosis device and a concentrated water adjustment valve, and is characterized in that: a three-bit digital tube is integrated on the switch panel; the switch panel is connected with the singlechip controller through a data wire; the low-voltage switch is connected to a water inlet through a polyurethane (PE) tube; an outlet of the low-voltage switch is connected to an inlet of the booster pump; an outlet of the booster pump is connected with the pressure gauge; the pressure gauge is connected with the reverse osmosis device; the concentrated water end of the reverse osmosis device is connected with the concentrated water adjustment valve; and the output end 1 of the singlechip controller is connected with the booster pump, and the output end 3 of the singlechip controller is connected with the low-voltage switch. The random cipher verification device with a protection function is developed specially to overcome the defect that a reverse osmosis membrane cannot be protected under certain conventional conditions.

Description

Random cipher consumptive material demo plant on a kind of water purification machine

Technical field

The utility model relates to the clocking capability of singlechip controller, the random cipher systematic function, and human-computer interaction function especially relates to the random cipher consumptive material defencive function on a kind of water purification machine.

Background technology

At present; The protection that the main components and parts reverse osmosis membrane of water purification machine on the market in use there is no need; Cause some producers to change the import reverse osmosis membrane on the water purification machine of laboratory, make the product deteriorating water quality, cause the lab assistant test normally to carry out with homemade family expenses film.

The utility model content

The purpose of the utility model is in order to overcome under existing some situation reverse osmosis membrane not to be protected, and special exploitation one cover has the random cipher demo plant of defencive function.

For realizing above purpose, the technical scheme that the utility model adopts: the random cipher consumptive material demo plant on a kind of water purification machine, it comprises switch panel, singlechip controller, low tension switch, supercharge pump, tensimeter, reverse osmosis unit, dense water regulating valve is formed; It is characterized in that: three charactrons are integrated on the switch panel, and switch panel links to each other with singlechip controller through data line; Low tension switch is connected to water inlet through the PE pipe, and the low tension switch outlet is connected on the inlet of supercharge pump, and the supercharge pump outlet connects tensimeter, and tensimeter connects reverse osmosis unit, and the dense water end (W.E.) of reverse osmosis unit is connected to dense water regulating valve; The output terminal 1 of singlechip controller connects supercharge pump; Singlechip controller output terminal 3 connects low tension switch.

The beneficial effect of the utility model: the operator after the timer on the single-chip microcomputer is accumulated to timing time, can send warning when using water purification machine, stop supercharge pump; The authentication password input that must have the manufacturer of water purification machine to provide just can be restarted supercharge pump; Prevent that some producers from adopting the family expenses film to change the import reverse osmosis membrane on the water purification machine of laboratory.

Fig. 1 is the synoptic diagram of the utility model.

Embodiment

As shown in Figure 1, the mode of operation in the utility model practical work process: after treated tap water was sent into low tension switch, singlechip controller output terminal 3 opened low tension switch; Low tension switch could be closed, and after the low tension switch closure, singlechip controller output terminal 1 starts supercharge pump; Pressurize to reverse osmosis unit; Regulate dense water regulating valve, make the reverse osmosis unit operate as normal, reverse osmosis produced water end (W.E.) produces pure water continuously; The working time of monolithic controller timer internal cumulative rises pump, promptly know working time of reverse osmosis membrane.When supercharge pump working time greater than 7200 hours (about 3 years), three charactrons produce one group of random data, supercharge pump quits work, and reminds the user need change reverse osmosis membrane.When changing reverse osmosis membrane, must tell the random cipher in 3 charactrons of original production producer, last digit position password authentification sign indicating number is got according to the password checking computations program Y=AX+B that configures in advance by producer.Wherein Y is the password authentification sign indicating number, and A is the production batch month of singlechip control panel, and X is one of three random code, and B is the production batch day of singlechip control panel.

Suppose: random cipher is 123, and A is 6, and B is 1, and Y=6*1+1 is 7 so, draw equally two outer two be 39.Obtaining the password authentification sign indicating number is 739.Through the last key on the switch panel, following key acknowledgement key is input in the single-chip microcomputer.The password authentification success, the supercharge pump reclocking, otherwise supercharge pump can not move.

Claims

1. the random cipher consumptive material demo plant on the water purification machine, it comprises switch panel, singlechip controller, low tension switch, supercharge pump, tensimeter, reverse osmosis unit, dense water regulating valve is formed; It is characterized in that: three charactrons are integrated on the switch panel, and switch panel links to each other with singlechip controller through data line; Low tension switch is connected to water inlet through the PE pipe, and the low tension switch outlet is connected on the inlet of supercharge pump, and the supercharge pump outlet connects tensimeter, and tensimeter connects reverse osmosis unit, and the dense water end (W.E.) of reverse osmosis unit is connected to dense water regulating valve; The output terminal of singlechip controller (1) connects supercharge pump; Singlechip controller output terminal (3) connects low tension switch.
