Abstract

The utility model provides an intelligent water-saving device for college trench type toilets. The intelligent water-saving device comprises an infrared sensor module, a clock module, a main control module, a button module, a display module and an electromagnetic valve control module and is characterized in that the main control module is respectively connected with the infrared sensor module, the clock module, the button module, the display module and the electromagnetic valve control module. According to college timetables, the button module sets corresponding water flushing modes; when the water-saving device is in an infrared mode, the infrared sensor module detects exercising human body signals, the main control module performs counting through the clock module, and the electromagnetic valve control module controls the on-off of an electromagnetic valve; and when the water-saving device is in a timing mode, the main control module performs timing through the clock module, and then the electromagnetic valve control module controls the on-off of the electromagnetic valve.

Description

Colleges and universities' plough groove type public lavatory intelligent water-saving device

Technical field

The utility model relates to a kind of water saving fixtures, especially colleges and universities' plough groove type public lavatory intelligent water-saving device.

Background technology

Along with economy and science and technology development; Water resource in short supply day by day; Water-saving strategy of sustainable development thought is the concern of society extremely, the present wasting phenomenon that occurs of some plough groove type public lavatory waters of colleges and universities, more existing water-saving systems or be the control mode of regularly washing by water; Be according to the number of setting control mode, but can't realize effective water saving.

Summary of the invention

In view of above these situation, the utility model provides a kind of human body infrared intelligent light controller.These water saving fixtures have not only been realized the timing working pattern according to colleges and universities' daily schedule, have also integrated counting and timing function under the infrared operation pattern, have realized Self Adaptive Control, have reached effective water saving purpose, and have met hygienic requirements.

The utility model provides a kind of colleges and universities plough groove type public lavatory intelligent water-saving device; Comprise infrared sensor module, clock module, main control module, key-press module, display module, solenoid control module, it is characterized in that: the main control module is connected with infrared sensor module, clock module, key-press module, display module, solenoid control module respectively.According to colleges and universities' daily schedule, key-press module is provided with corresponding bath pattern, and when being in infrared mode, the infrared sensor module detects the moving human body signal, and the main control module is counted through clock module, then the break-make of solenoid control module controls electromagnetic valve.When being in timing mode, the main control module is carried out timing through clock module, then the break-make of solenoid control module controls electromagnetic valve.

The beneficial effect of the utility model is, and is simple in structure, and cost performance is high, and stable performance is suitable for the application and the popularization of colleges and universities' plough groove type public lavatory water saving, has advantages of high practicability.

Fig. 1 is the theory diagram of the utility model; Fig. 2 is the electric structure chart of the utility model.

The specific embodiment

In Fig. 1; The utility model provides a kind of colleges and universities plough groove type public lavatory intelligent water-saving device; Comprise infrared sensor module 1, clock module 2, main control module 3, key-press module 4, display module 5, solenoid control module 6, it is characterized in that: main control module 3 is connected with infrared sensor module 1, clock module 2, key-press module 4, display module 5, solenoid control module 6 respectively.According to colleges and universities' daily schedule; Key-press module 4 is provided with corresponding bath pattern, and when being in infrared mode, infrared sensor module 1 detects the moving human body signal; Main control module 3 is counted through clock module 2, then the break-make of solenoid control module 6 control electromagnetic valve.When being in timing mode, main control module 3 is carried out timing through clock module 2, then the break-make of solenoid control module 6 control electromagnetic valve.

In Fig. 2, what main control module 3 adopted is the single-chip microcomputer of 89S52, and 89S52 reads the real-time clock data of clock module 2, and through data, clock data to be shown shows thereby drive display module 5 with serial transfer mode to 7219.What clock module 2 adopted is the DS12887 clock chip, and its working power is 5V, and MOT ground connection is the INTEL sequential; AS address latch, DS read signal, R/W write signal are connected with ALE, RD, the WR of 89S52 respectively, and AD0 ~ AD7 is the address/data multiplex bus, are connected with the P0 mouth of 89S52 respectively; RESET need guarantee the above low level ability of 200m s reliable reset when powering on; CS is the chip selection signal of DS12887, and low level is effective, is connected for 7 mouthfuls with the P2. of 89S52; The high eight-bit address of DS12887 is 7FH so, and low eight bit address are then decided by its inner each element address.89S52 is operated in timing mode or infrared mode according to the clock data decision systems that reads; Whether the break-make decision according to hand switch uses the function that manually discharges water; Satisfying under the various situation that discharge water; By 6 mouthfuls of break-makes of coming control electromagnetic valve control module 6 of P1. of 89S52, thereby the break-make of control electromagnetic valve is to reach the control requirement.When infrared sensor module 1 detects the moving human body signal, pin 2 output 3V level, triode 9014 saturation conductions; The detection indicator lamp is bright, and 2 pin of photoelectrical coupler are because of being pulled down to the low level conducting, and its 4 pin also is pulled down to low level; When no moving human body signal, 2 pin of detection components are output as 0, and triode ends; The detection indicator lamp extinguishes, and 2 pin of photoelectrical coupler are pulled to high level, and the output pin 4 of photoelectrical coupler also is pulled to high level.What key-press module 4 adopted is 4 * 4 matrix keyboards, and one has 16 keys, is respectively numerical key 0 ~ 9 and function key A ~ F.
