Step (1) was divided into 96 time periods by 24 hours, and 15 minutes each time periods, single-chip microcomputer detects water dispenser in the operating state of each time period by current detection module, and records the heating times of each time period;
Step (2) is carried out sequence from big to small by the heating times of each time period of two weeks interior single-chip microcomputer records, using N section heating time before heating the most frequently as the reference hot spot of next week; N is natural number.And N is less than 10;
Step (3) records the heating times of new one week each time period, and compare with reference hot spot before, if heating times two Zhou Douwei of reference hot spot before enter front N, cancel this with reference to hot spot, otherwise continue to continue to use this with reference to hot spot; If occur, the heating times of new hot spot all enters front N in continuous two weeks, using this new hot spot as reference hot spot next time; If not used hot water in continuous 4 hours of user detected, it is abnormal that socket will judge that this sky of user occurs, to directly cut off the electricity supply, no longer carry out the intelligent mode heating, now the infrared induction module still works, if this sky of user needs water, the infrared induction module is when sensing the user near water dispenser, the automatic opening power of meeting, enter the intelligent work pattern; If one week interior three days or above appearance abnormal (in one day, within continuous 4 hours, there is no the heating after water), the data in this week are invalid data for extremely all this week;
As shown in Figure 8, for the present invention, each modular circuit is merged to the schematic diagram of the circuit board of finally making.This circuit board size is 7.5cm*7.5cm, and L, N are live wire and zero line interface, receives on the 220V civil power to deliver to power module and drive whole circuit board work, and L1, N1, for live wire and the zero line of this pcb board output, will finally be used for driving water dispenser work.
As shown in Figure 9, the jack housing size is 8cm*8cm, and the water dispenser plug is inserted on this socket, and the socket face is circuit board, wherein infrared, photosensitive, indicator are three apertures, and PIR infrared probe, photo resistance and indicator light will pass from aperture.Be key switch in button place one aperture, can carry out button operation by the mode of inserting nib, select mode of operation.
Performance evaluation of the present invention is as follows:
The present invention adopts the uPD78F9202 single-chip microcomputer of NEC 78K0S series, and overall design adopts light sensation module, infrared induction module and intelligent memory algorithm to realize the energy-conservation purpose of water dispenser.Water dispenser, by learning by oneself user's water habits, can identify the working hour commonly used of every day.Light sensation module and infrared induction module are assisted.For the intelligent memory algorithm, socket can be stored user's water situation of nearest 4 weeks, to set up the heating reference point.The data of this storage will be updated once after within one week, finishing, and add the data of up-to-date a week, reject the data of a week the earliest.After data are updated, socket re-establishes hot spot, as the heating reference point in next week, and so circulation, unceasing study user water habits.And light sensation module, infrared induction module are opened the water dispenser power supply so that water dispenser enters the intelligent work pattern by induction.
Such as the routine work period is 9:00-17:00, when certain luminous intensity is sensed in the photo resistance of light sensation module in the morning, the water dispenser power supply is opened, and enters the intelligent work pattern.Suppose user's general custom in the morning 9:00 drink water, this point just as the reference hot spot of water dispenser, socket will shift to an earlier date 30 minutes and be heated, and when 9:00 user needs water, just can use.And socket can be recorded the user simultaneously and whether at this time period water, considers whether retain this hot spot.If the number of times that in a week, this point drinks water is less than 2 times, this heating reference point will be disallowable.For some special circumstances:
(1) if socket detection to not used hot water in continuous 4 hours of user, socket will judge that this sky of user belongs to special state, will directly cut off the electricity supply, and no longer carry out the intelligent mode heating.Now the infrared induction module still works, if this sky of user needs water, the infrared induction module is when sensing the user near water dispenser, and the automatic opening power of meeting, enter the intelligent work pattern;
(2) generally in office space, be no more than 17:00 normal working hours, 17:00 reference hot spot is afterwards seldom arranged in the ordinary circumstance of socket record.What now work is the light sensation module, and when the light sensation module detects office space when the unsocial hours still has the user, socket still can be controlled drinking machine heating, to guarantee the demand of user's water.
Embodiment 1:
The present invention is used for to the bedroom water dispenser, obtain following test data as shown in table 1, wherein the last fortnight is the single-chip learning time, the rear test of carrying out each side in two weeks, mainly measured the accuracy of power consumption, infrared induction and light sensation module working condition and hot spot, test result is as table 1:
The every test index of table 1. intelligent drinking machine
