Problems solved by technology
In addition, since the current automatic flushing equipment with reflective infrared sensors counts the time of continuous reflection signals, once the human body shakes away from the effective reflection range when using the toilet, the reflected signals disappear instantly, which will also cause automatic flushing. Unreasonable flushing due to equipment misjudgment
In particular, toilets that use solenoid valves as water outlet control devices have small water volumes and are easily affected by changes in water supply pipeline flow and water pressure, and the flushing effect is poor; However, there is a disadvantage of poor flushing effect
Therefore, this type of infrared sensing equipment, especially the reflective infrared signal type squat urinal and toilet automatic flushing control equipment, lacks practicability in real life.

[0022] As shown in Figures 1, 2, 3, and 5: Ultrasonic sensing type squat urinal intelligent flushing controller, the controller box 16 is installed on the flushing pipeline 22, and the installation height is such that the ultrasonic sensing head is not reflected by the ground. The interference of the ultrasonic signal shall prevail. The solenoid valve 21 is directly installed in the flushing pipeline 22, and is connected with the output control terminal of the central microprocessor 14 on the main control circuit 15. The device is the same, and the working principle is the same.
[0023] Compared with the existing urinal automatic flushing controller, the ultrasonic sensing type intelligent flushing controller and the double anti-false triggering signal processing method provided by the invention have the following beneficial effects:
[0024] In the present invention, through the cooperation of the ultrasonic sensor and the central microprocessor, the controller can accurate...

The invention discloses a supersonic sensing intelligent rinsing control and double false-protection ignited signal processing method, the controller classifies the signal reflected by human body in the preset effective distance through transmitting supersonic wave and processes with double false-protection means, it can incriminate the behavior of people using the piss pool, the squat pool and the closestool accurately, and carries on rinsing process with different quantity, is solves the problem that the reliability with infrared sensor incrimination is bad, thus the automatic rinsing controller can be applied to complex application environment such as restaurant, hotel, building and house toilet fully.
Description
Technical field: [0001] The invention relates to the technical field of toilet automation control, in particular to the technical field of automatic flushing control equipment for urinals, squatting urinals or toilets. Background technique: [0002] At present, the inductive urinals, squatting urinals or toilet automatic flushing control equipment used in the bathroom all use reflective infrared sensors, or use pyroelectric infrared sensors and reflective infrared sensors to use two sensing methods in order to save power consumption. The water outlet control devices are solenoid valves or water valve motors. The former works as follows: when standing at a certain distance in front of the urinal, the infrared sensor is triggered, and the infrared sensor sends a level signal to the back-end control system. After urinating and leaving, the infrared sensor stops sending the level signal and returns to the standby detection state. The control system sends out a level or pulse si...
