Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1, an embodiment of the present invention provides an intelligent control system for a toilet, including a monitoring system, an execution system, and a control system;
the execution system comprises a ventilation fan and a lighting lamp;
the monitoring system comprises an infrared heat sensor and a photoelectric sensor, wherein the infrared sensor is used for monitoring whether a person enters a toilet or not, and the photoelectric sensor is used for monitoring the illumination intensity of the toilet;
the control system judges whether the lamp needs to be turned on or the air needs to be exchanged according to the information monitored by the monitoring system. A time threshold value and an illumination threshold value are set in the control system; the infrared sensor continuously detects the use time of a person entering a toilet, and the ventilation fan is started when the use time is greater than a time threshold value by comparing the use time with the time threshold value; the photoelectric sensor monitors the numerical value of the illumination intensity, and judges whether to start the illuminating lamp or not by comparing the numerical value with an illumination threshold value; specifically, the infrared pyroelectric sensor is used for detecting whether a person enters a toilet or not, continuously detecting the person and determining the intention of the person to enter the toilet by a certain time threshold, the photoelectric sensor is used for detecting the actual value of the illumination intensity of the toilet, the actual value of the illumination intensity of the toilet is compared with the set threshold in the microcomputer to determine whether the illumination lamp needs to be turned on for illumination or whether the ventilation fan needs to be turned on for ventilation of the toilet or not.
The control system adopts a singlechip microcomputer, and an editable logic module is arranged on the singlechip microcomputer.
In specific application, the microcomputer controller firstly detects the output value of the infrared heat release sensor, and if the output value is high level, the microcomputer controller immediately detects the illumination value of the current toilet. According to the comparison between the currently detected illuminance value and the current illuminance threshold value set in the microcomputer, there are two control ways according to the comparison result.
(1) ① if the input value is changed to low level, it indicates that the user enters the toilet for a short time (for example, take one thing in the toilet), and does not need to use the toilet and leaves the toilet within 10s, it controls to return to the detection of the input value of the infrared heat release sensor at the beginning to prepare to enter the next detection and control, ② if the input value is still high level, it indicates that the user does not leave within 10s, and needs to use the toilet, at this time, the input value of the infrared heat release sensor is started, then the input value of the infrared heat release sensor is detected once every 5s, if the input value is high level, it indicates that the user is still using the toilet, the ventilator is kept in the on state until the input value of the infrared heat release sensor is changed to low level, it indicates that the user has left the toilet, the timing is started, ventilation is continued to be closed after 60s, then the control returns to the input value of the infrared heat release sensor at the beginning to prepare to detect the next detection and control the ventilator.
(2) ① if the input value is changed to low level, it indicates that the user enters the toilet for a short time, should immediately turn off the lamp, then control returns to the infrared heat release sensor input value detection at the beginning to prepare for the next detection and control. ② if the input value is still high level, it indicates that the user does not leave in 10s, should use the toilet, at this time, should turn on the ventilation fan, then detect the infrared heat release sensor input value once every 5s, if it is high level, it indicates that the user is still using the toilet, maintain the lamp and the ventilation fan in the on state until the infrared heat release sensor input value is changed to low level, it indicates that the user has left the toilet, at this time, should immediately turn off the lamp, start timing, continue ventilation, turn off after 60s, then control returns to the next detection of the heat release sensor at the beginning, and prepare for the next detection of the infrared heat release sensor.
