Technical Field

[0001] The invention relates to the technical field of infrared sensing equipment control, and in particular to a parameter adjustment method of an infrared sensing water outlet controller. Background Art

[0002] With the advancement of technology and the improvement of the requirements for the use environment, more and more urinals and toilets are equipped with automatic induction flushing, replacing the traditional flushing mode that requires manual operation. In the application field of automatic induction flushing, infrared induction flushing solutions have been more widely used due to their low power consumption, low cost and easy implementation.

[0003] Infrared induction water controller is used in automatic water flushing toilets. After installation, there is no way to adjust the parameters using a visual interface. Due to the influence of the installation angle, reflective surface, illumination, and water pressure, it is necessary to adjust the flushing time and the sensing distance after installation, which requires complex operations to complete. Therefore, the existing parameter adjustment method of infrared induction water controller has the following defects:

[0004] (1) The operation is complicated; (2) There is no visual interface and the adjustment parameters cannot be displayed; (3) It takes a lot of time to adjust the parameters and the efficiency is low; (4) It is necessary to observe the sensor controller to determine whether the parameters have been modified correctly, but the sensor controller has only one indicator light. The parameter judgment scheme is relatively complicated and difficult for general engineering and technical personnel to master. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention proposes a parameter adjustment method for an infrared sensing water outlet controller, which can be operated through a visual interface, is easy to operate, and has high adjustment efficiency.

[0006] In order to realize the above technical solution, the present invention provides a parameter adjustment method of an infrared sensing water outlet controller, which specifically comprises the following steps:

[0007] S1, the power module converts the mains power into a low-voltage DC power supply to power the MCU of the sensor controller;

[0008] S2, MCU transmits signals to detect distance through infrared transmitting tube. When an object approaches, the receiving tube receives the return signal of the detected object distance information.

[0009] S3, MCU detects the appropriate object distance by calculating the infrared transmission signal and the infrared reception signal, and controls the electromagnetic water valve according to the preset parameter logic to realize the water opening and closing functions;

[0010] S4, the receiving tube of the induction controller receives the infrared induction signal of the detection distance and receives the parameter setting command of the visual remote controller at the same time;

[0011] S5, when the induction controller receives the parameter setting command of the visual remote controller, the induction controller state parameters are sent to the visual remote controller according to the coding structure through the transmitting tube;

[0012] S6, the visual remote controller starts the remote control and sets the parameters by operating the buttons;

[0013] S7, the receiving tube of the visual remote controller receives the coding structure of the sensing controller status signal, and displays the received coding structure parameters in text on the display screen;

[0014] S8, the transmitter tube of the visual remote control controls the parameters pre-configured by the remote control through buttons, and sends the parameters through the transmitter tube according to the coding structure of the new parameters;

[0015] S9, the induction controller receives the new setting parameters of the visual remote controller, saves them to the memory of the induction controller, and sends a confirmation signal to the visual remote controller;

[0016] S10, the visual remote control shows that the setting is successful, and the induction controller works according to the newly set parameters.

[0017] Preferably, the object distance detected in step S3 includes the distance between a human body or a palm and the infrared emitting tube.

[0018] Preferably, the parameter encoding structure in step S5 and step S7 is the same, and the encoding structure is as follows:

[0019]

[0020] Preferably, the encoding structure of the new parameter sent by the visual remote controller in step S8 is as follows:

[0021]

[0022] Preferably, in step S8, the parameters sent by the transmitting tube include sensing distance, flushing time and flushing mode.

[0023] Preferably, during the operation of setting parameters in step S6, the transmitting tube and the receiving tube of the visual remote controller are respectively aligned with the receiving tube and the transmitting tube of the induction controller, kept in a horizontal straight line, and the distance is within the range of 5cm-40cm.

[0024] The beneficial effects of the parameter adjustment method and control method of the infrared induction water outlet controller provided by the present invention are:

[0025] (1) After the infrared sensing water outlet controller is installed, the present invention can use a visual remote control with parameter display to modify the sensing distance, flushing time, flushing mode and other parameters of the water outlet controller, which is easy to operate and has high adjustment efficiency.

[0026] (2) In the prior art parameter adjustment, the remote controller has no display screen, while the parameter adjustment remote controller of the present invention is equipped with a display screen, which can directly display the parameter content.

[0027] (3) In the prior art, the remote controller only has a transmitting function but no parameter receiving function. In the present invention, the remote controller is equipped with an infrared receiving tube and can receive the status parameters sent by the induction controller.

[0028] (4) In the prior art, the receiving tube of the induction controller receives commands and distance signals, and the infrared transmitting tube of the induction controller can only send infrared distance detection signals. In the present invention, the infrared transmitting tube of the induction controller can transmit infrared distance detection signals and also transmit the state parameters of the induction controller to the visual remote controller.

[0029] (5) The inductive controller in the present invention sends parameters, and the coding structure uses pulse width to represent digital information. The pulse width range is 20%, and the digital high level is subjected to a 37KHz-39KHz frequency carrier with a center frequency of 38KHz, which can effectively enhance the accuracy of parameter transmission and reception, and has a fast response without lag.

[0030] (6) The visual remote controller of the present invention sends setting parameters, and the coding structure uses pulse width to represent digital information, and the pulse width range is 20%. This coding structure can reduce the design requirements of the receiving and transmitting tube of the induction controller, so that the induction controller can receive the distance control signal, and the receiving tube of the induction controller does not need to demodulate the carrier function, and can also receive the setting parameters of the remote controller, which is simple to operate and has high adjustment efficiency.

[0037] Based on the above-mentioned parameter adjustment system of the infrared sensing water outlet controller, the present invention provides a parameter adjustment method of the infrared sensing water outlet controller, which specifically includes the following steps:

[0038] (1) The sensor controller power module 01 converts the mains power into a low-voltage DC power supply (6V) to supply power to the sensor controller MCU module 02;

[0039] (2) The sensor controller MCU module 02 transmits a signal to detect the distance through the sensor controller infrared transmitting tube 04. When an object approaches, the sensor controller infrared receiving tube 03 detects the return signal of the object distance information;

[0040] (3) The sensor controller MCU module 02 detects the appropriate object distance by calculating the infrared transmission signal and the infrared reception signal, and controls the electromagnetic water valve 06 according to the preset parameter logic to realize the water opening and closing functions, wherein the detected object distance includes the distance between the human body or palm and the infrared transmission tube 04 of the sensor controller;

[0041] (4) The infrared receiving tube 03 of the induction controller receives the infrared induction signal of the detection distance and receives the parameter setting command of the visual remote controller at the same time;

[0042] (5) When the induction controller receives the parameter setting command of the visual remote controller, the induction controller state parameters are sent to the visual remote controller according to the coding structure through the induction controller infrared transmitting tube 04; the coding structure of the state parameters sent by the induction controller transmitting tube 04 is shown in Table 1:

[0043] Table 1 Induction controller transmitter state parameter encoding structure

[0044]

[0045]

[0046] The above-mentioned induction controller sends parameters, and the coding structure uses pulse width to represent digital information, the pulse width range is 20%, and the digital high level is subjected to 37KHz-39KHz frequency carrier, and the center frequency is 38KHz, which can effectively enhance the accuracy of parameter transmission and reception, and respond quickly without lag.

[0047] (6) After the visual remote control battery box is installed with batteries, the visual remote control button 14 can be operated to start the remote control and set parameters. During the operation, the visual remote control transmitting tube 11 and the visual remote control receiving tube 12 are respectively aligned with the induction controller infrared receiving tube 03 and the induction controller infrared transmitting tube 04, and are kept in a roughly horizontal straight line position with a distance of 5cm-40cm.

[0051]

[0052]

[0053] The above-mentioned visual remote control sends the setting parameter coding structure using pulse width to represent digital information, and the pulse width range is 20%.

The operation is simple and the adjustment efficiency is high.

[0054] (9) The induction controller receives the new setting parameters of the visual remote controller (according to the coding structure of Table 2), saves them to the induction controller memory EEROM, and sends a confirmation signal to the visual remote controller.

[0055] (10) The visual remote control shows that the setting is successful, and the sensor controller will work according to the newly set parameters (sensing distance, flushing time, flushing mode).

[0056] In the present invention, after the infrared sensing water outlet controller is installed, the present invention can use a visual remote control with parameter display to modify the sensing distance, flushing time, flushing mode and other parameters of the water outlet controller, which is easy to operate and has high adjustment efficiency. Compared with the prior art, the prior art parameter adjustment, the remote control has no display screen, and the present invention is configured with a display screen when adjusting the parameters, which can directly display the parameter content. Compared with the current technology, the prior art parameter setting, the remote control only has a transmitting function, but no parameter receiving function, and the present invention is configured with an infrared receiving tube when adjusting the parameters, which can receive the status parameters sent by the sensing controller. Moreover, in the prior art parameter setting, the sensing controller receives commands and distance signals, but the infrared transmitting tube of the sensing controller only sends infrared distance detection signals. In the present invention parameter setting, the infrared transmitting tube of the sensing controller can not only transmit infrared distance detection signals, but also transmit the status parameters of the sensing controller to the visual remote control.

In the present invention, the visual remote control sends setting parameters, and the coding structure uses pulse width to represent digital information, the pulse width range is 20%. This coding structure can reduce the design requirements of the induction receiving and transmitting tube, so that the induction controller can receive the distance control signal, the induction controller receiving tube does not need to demodulate the carrier function, and can also receive the setting parameters of the remote control, the operation is simple, and the adjustment efficiency is high.
