Below in conjunction with accompanying drawing, introduce in detail embodiment.
As shown in Figure 1-Figure 3.Control circuit of the present invention is comprised of single-chip microcomputer, sensor, magnetic valve and drive circuit thereof, counting display circuit and voltage-stabilized power supply.Wherein:
Whether sensor has the height of water container, water container, the liquid level in water container for detection of beverage machine discharging opening place.The output of sensor connects the data input port (P0, P2, P10-P12) of single-chip microcomputer.
Magnetic valve is for opening and closing beverage machine tap according to the signal of sensor, and the input of the drive circuit of magnetic valve connects the output of single-chip microcomputer (P13-P15).
Counting display circuit is for adding up the cup number of beverage machine discharging.The input of counting display circuit connects the data output of single-chip microcomputer.
Voltage-stabilized power supply provides DC supply for control circuit.
The sensor comprises photoelectric sensor group and ultrasonic sensor, wherein: whether photoelectric sensor group has water container for detection of beverage machine discharging opening place and detect the height of water container, and ultrasonic sensor is for detection of the liquid level in water container.
Above-mentioned counting display circuit is in series by counter, decoder, light-emitting diode display, and the input of counter connects the data output of single-chip microcomputer, and single-chip microcomputer can be to counter O reset.
As shown in Figure 4.Photoelectric sensor 6 is arranged on the below of beverage machine discharging opening 5, and photoelectric sensor 6 can detect the height whether beverage machine discharging opening place has water container 7 and detect water container 7.Ultrasonic sensor 4 is arranged on the top of beverage machine discharging opening 5, and ultrasonic sensor 4 can detect the height of liquid level in water container 7.Light-emitting diode display 3 is arranged on beverage machine panel upper right side.Indicator lamp 2 is arranged on beverage machine panel upper left side.
Ultrasonic sensor 4 is contained in to the top of water container 7, only, by the position of delivery port, such one is to save space, the 2nd, and in order to measure better the height of the liquid level in water container.
Photoelectric sensor is assembled on a side ancient piece of jade, round, flat and with a hole in its centre for water container side water dispenser.Photoelectric sensor adopts refraction type, and the measuring distance of photoelectric sensor is debugged and equaled sensor to the distance of discharging opening center line subpoint.The little existence that does not detect water container of distance, easy generation erroneous judgement that distance is large.In order to prevent that non-water container from causing erroneous judgement, first, photoelectric sensor is identified from bottom to top, and photo-sensor signal will is continuous, otherwise just judgement is not water container.Sensor adopts hardware and software in conjunction with identification herein, hardware is photoelectric sensor, when having a glass class container to block sensor, refraction type photo-sensor feedback signal, but for reliably, avoid erroneous judgement, single-chip microcomputer is received after the signal that all sensors send here can time delay 0.5 second, when nethermost sensor has signal and successively effectively time, single-chip microcomputer judgement is glass class container the height that calculates container, if there is below, middle sensor is invalid, illustrate and be not that container or cup do not put well etc.; Secondly, the liquid level that ultrasonic sensor detects must be lower than water container height; Meeting above two condition rear electromagnetic valves can open.Magnetic valve adopts and establishes formula (being normally closed type) by cable, prevents power-off gravity flow.
Figure 5 shows that software flow pattern of the present invention.When have people cup class container is put into beverage machine discharging opening under time, sensor starts identification, if the signal of identification effectively carries out delay process, object is to determine that cup put steady and operator's hand and left, to avoid scalding operator.Single-chip microcomputer calculates the height of container, because of cup, can not fill with too fullly, otherwise can produce, drop, therefore, by measuring height deduct again container along high, obtain the injecting height of answering of liquid.Ultrasonic wave is tracer liquid liquid level making comparisons with answering injecting height at any time, opens magnetic valve when being less than, start and continue to inject, and shut electromagnetic valve when equaling, being greater than, statistics calculator adds 1, gets back to beginning wait state.
During use, user by water container 7 be put into beverage machine discharging opening 5 under, photoelectric sensor group detects exit to be had after the height of water container 7 and water container 7, control circuit is just opened outlet magnetic valve automatically, to water filling in water container 7.Ultrasonic sensor 4 is now the height of liquid level in detecting water container 7 also, and when liquid level will reach the height of water container, control circuit just stops magnetic valve automatically.When people take water container 7 away, counter adds one automatically, and shows output through LED, automatically adds up discharging cup number.
The present invention can reach following effect:
1. can make people use safely, avoid scalding;
2. can reduce overflow, avoid waste;
3. can prevent that staff from touching beverage, health is reliable;
4. can automatically add up and sell a glass number, facilitate service management.
In control circuit of the present invention, every group of photoelectric sensor delivered to single-chip microcomputer internal conversion and become effective binary numeral: 00000000---11111111 form, must be continuously between 000 or 111, otherwise invalid.Because the output of sensor is had plenty of " 1 " and has plenty of " 0 ", if discontinuous between 000 or 111, what show to be placed on beverage machine discharging opening below is not that container or cup are not put well etc.Effectively be set in software program and set.Take " 1 " be example effectively time, " 1111110000 ", " 111111110 ", " 11111111111 " are effective.When there are " 011111100 ", " 111110111 ", " 110110110 " etc., it is invalid signals.The analog quantity that ultrasonic sensor measures is converted into digital quantity, and compares with the digital quantity of photoelectric sensor group, according to fiducial value, judges output.
Counter adopts decade counter 74LS192, with the trailing edge of the driving pulse in driving circuit for electromagnetic valve, triggers, and seven sections of decoder drivers can adopt CD4511,74LS47 etc., and LED adopts common cathode mode or common anode utmost point mode.The drive circuit of magnetic valve can be LM298, MS33886 etc.
In addition, the beverage sales business who considers needs halfway counting again, therefore can set up reset switch in the circuit of Fig. 1.If sometimes need to start counting from middle certain point, also can set up prefabricated several circuit, counter 74LS192 circuit has special corresponding control port.
