The present invention can be implemented or applied through other different specific embodiments, and the details in this specification can also be modified and changed in various ways based on different viewpoints and applications without departing from the concept of the present invention.

The following embodiments will further explain the relevant technical contents of the present invention in detail, but the disclosed contents are not intended to limit the scope of protection of the present invention.

[0043] Embodiment 1

[0044] like Figure 1 As shown, the present invention provides a slow start control device, which includes a microprocessor 1, a control unit 10, a switching device 20, and a fine-tuning program 30. The microprocessor 1 can be a central processing unit (CPU), a controller, or a multiplexer. The control unit 10 has a driving circuit board 101, and the driving circuit board 101 uses a pump 40 device to provide a power source for the switching device 20, and the pump 40 is used to open and / or close the switching device 20.

[0045] The switching device 20 has a valve form. Specifically, the switching device 20 can be a valve, a solenoid valve, a proportional valve, a multi-way valve or a piezoelectric valve. The control unit 10 sends a forward continuous signal to the switching device 20, so that the switching device 20 gradually reaches a fully open state. The control unit 10 sends a reverse continuous signal to the switching device 20, so that the switching device 20 gradually reaches a fully closed state. The receiving device for the switching device 20 to open and / or close can be an air bag 50 or an air bag.

[0046] Among them, when the fine-tuning program 30 performs a time-phased adjustment on the open state of the switching device 20, and at the same time performs a time-phased adjustment on the closed state of the switching device 20, the fine-tuning program 30 is used to calculate the average opening and / or closing time of the switching device 20, thereby obtaining the optimal opening and / or optimal closing control interval value.

[0047] Thus, the slow-start control device of the present invention can send a positive signal (from closed to open) and a reverse signal (from open to closed) to the switching device 20 in real time through the control unit 10, thereby obtaining an optimized control signal.

[0048] Embodiment 2

[0049] like Figure 2 As shown, compared with the first embodiment, the difference is that the switching device 20 can be specifically configured as a valve switching device (a three-way valve is used as an example for explanation in this embodiment).

[0050] When the control unit 10 is activated, the driving circuit board 101 sends a power source signal to the pump 40 device. After the pump 40 generates fluid, the three-way valve 201 of the switching device is opened and / or closed through the air inlet 202. The three-way valve 201 of the switching device 20 then inputs the fluid into the air bag 50 or the airbag through the air outlet 203. In addition, the three-way valve 201 of the switching device can also discharge the fluid to the external atmosphere through the pressure relief outlet 204.

[0051] By utilizing the design of the present invention, when the control unit 10 sends a forward continuous signal to the switching device 20, the switching device 20 gradually reaches a fully open state. In addition, the control unit 10 sends a reverse continuous signal to the switching device 20, so that the switching device 20 gradually reaches a fully closed state. The fine-tuning program 30 is used to adjust the time of the open state of the switching device 20 in stages, and the time of the closed state of the switching device 20 is adjusted in stages at the same time. The average opening and / or closing time of the switching device 20 is calculated, and the optimal opening and / or optimal closing control interval value is obtained.

[0052] Through the above operation, the slow start control device of this embodiment can immediately send a forward signal (off to on) and a reverse signal (on to off) to the switching device 20 through the control unit 10, thereby obtaining an optimized control signal to prevent the switching device 20 from generating excessive noise during the repeated cyclic switching of the forward signal and the reverse signal.

[0053] like Figure 3 FIG. 2 is a flowchart of a forward continuous signal---opening state determination process according to a second embodiment of the present invention.

[0054] When the control unit is started, the switching device is first used to open the device, and the opening state of the switching device is adjusted in stages according to the fine-tuning program, and the average opening time of the switching device is calculated. At this time, the system determines whether the switching device has gradually reached a fully open state.

[0055] If the system determines that it has not yet reached the fully open state (reading No), it will re-perform the action of switching the device to open; conversely, if the system determines that it has reached the fully open state (reading Yes), the system will set this action time as the optimal opening control interval value.

[0056] like Figure 4 FIG. 2 is a flowchart of a reverse continuous signal---a closed state judgment process according to the second embodiment of the present invention.

[0057] When the control unit is started, the switching device is first used to close the device, and the closing state of the switching device is adjusted in stages according to the fine-tuning program, and the average closing time of the switching device is calculated. At this time, the system determines whether the switching device has gradually reached a completely closed state.

[0058] If the system determines that it has not yet reached the fully closed state (reading No), it will re-perform the action of closing the switching device; conversely, if the system determines that it has reached the fully closed state (reading Yes), the system will set this action time as the optimal closing control interval value.

[0059] like Figure 5 The test result of the slow start control device of the second embodiment of the present invention is shown in FIG. The test environment of this embodiment is to switch the switching device with a three-way valve switch device, the pump device is an air pump, and the test condition of a single air bag is carried out.

[0060] When the slow start circuit is not enabled to open the three-way valve, the noise level will be as high as 55.6 (Db); when the slow start circuit is enabled to open the three-way valve with a reverse continuous signal, the noise level will slightly drop to 53.9 (dB); when the slow start circuit is enabled to open the three-way valve with a forward continuous signal and a reverse continuous signal, the noise level will significantly drop to 44.6 (dB).

[0061] The above experimental data comparison proves that the slow start control system of this embodiment can indeed send a forward signal (off to on) and a reverse signal (on to off) to the switching device through the control unit. In addition to obtaining an optimized control signal, it can also further prevent the switching device from generating excessive noise during the repeated cyclic switching of the forward continuous signal and the reverse continuous signal.

[0062] Embodiment 3

[0063] like Figure 6 As shown, compared with the first embodiment, the difference is that the switching device 20 can specifically set an intelligent control system 21 and a channel 22.

[0064] Among them, the intelligent control system 21 is set with an open mode and a closed mode. The intelligent control system 21 provides an open mode signal to gradually change the switching device 20 from the closed state to the optimal open state. At the same time, the intelligent control system 21 provides a closed mode signal to gradually change the switching device 20 from the open state to the optimal closed state.

[0065] In this embodiment, the intelligent control system 21 obtains the optimal opening mode fluid volume and the optimal closing mode fluid volume of the channel 22 through a pulse width modulation (PWM) method.

[0066] like Figure 71 is an enlarged simulation illustration of the dotted line local position of the third embodiment of the present invention. After the pump 40 generates fluid, the fluid is input into the switching device 20 through the air inlet.

[0067] The valve assembly 23 in the switching device 20 determines whether to open or close the channel (actuated by the stretching force on both sides) through the intelligent control system 21, and uses the intelligent control system 21 to simultaneously obtain the optimal opening mode fluid volume and the optimal closing mode fluid volume of the channel 22.

[0068] like Figure 8 The figure shows the process flow of the intelligent control system of the third embodiment of the present invention - the opening state judgment process. When the valve assembly is activated by the intelligent control system, the switching device is first used to perform the opening action, and the pulse width modulation (PWM) method is used to determine whether the optimal opening mode fluid volume has been reached.

[0069] If the system determines that the optimal opening mode fluid volume has not yet been reached (reads No), the valve assembly will be opened again; conversely, if the system determines that the optimal opening mode fluid volume has been reached (reads Yes), the system will set this actuation time to open the valve assembly to the optimal opening mode fluid volume.

[0070] like Fig. 9 The figure shows the process flow of the intelligent control system of the third embodiment of the present invention - the closed state judgment process. When the valve assembly is activated by the intelligent control system, the switching device is first used to perform the closing action, and the pulse width modulation (PWM) method is used to determine whether the optimal closed mode fluid volume has been reached.

[0071] If the system determines that the optimal closing mode fluid volume has not yet been reached (reads No), the valve assembly will be closed again; conversely, if the system determines that the optimal closing mode fluid volume has been reached (reads Yes), the system will set this actuation time to close the valve assembly to the optimal closing mode fluid volume.

[0072] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technician familiar with the profession can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
