Detailed Description
The following embodiments of the present invention are described in terms of specific examples, and those skilled in the art will appreciate the advantages and effects of the present invention from the disclosure herein. The invention is capable of other and different embodiments and its several details are capable of modifications and various other uses and applications, all of which are obvious from the description, without departing from the spirit of the invention. The drawings of the present invention are merely schematic illustrations, and are not intended to be drawn to actual dimensions. The following embodiments will further illustrate the related art content of the present invention in detail, but the disclosure is not intended to limit the scope of the present invention.
Example 1
As shown in fig. 1, 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 may be a Central Processing Unit (CPU), a controller (controller), a multiplexer (multiplexer). The control unit 10 has a drive circuit board 101, and the drive circuit board 101 provides a power source for the switching device 20 by using the pump 40 device, and performs an opening and/or closing operation of the switching device 20 by the pump 40.
The switching device 20 has the form of a valve, in particular the switching device 20 may be a valve, a solenoid valve, a proportional valve, a multi-way valve or a piezo valve. The control unit 10 sends a forward continuous signal to the switching device 20 to gradually turn on the switching device 20, and the control unit 10 sends a reverse continuous signal to the switching device 20 to gradually turn off the switching device 20, so that the receiving device for opening and/or closing the switching device 20 can be an air bag 50 or an air bag.
When the fine tuning program 30 performs time-staged adjustment on the on state of the switching device 20 and simultaneously performs time-staged adjustment on the off state of the switching device 20, the fine tuning program 30 calculates the average on and/or off time of the switching device 20, thereby obtaining the optimal on and/or off control interval value.
Therefore, the slow start control device of the present invention can send the forward signal (off to on) and the reverse signal (on to off) to the switching device 20 through the control unit 10 in real time, thereby obtaining the optimized control signal.
Example two
As shown in fig. 2, a difference from the embodiment is that the switching device 20 may be specifically provided as a valve switching device (a three-way valve is exemplified in the present embodiment).
When the control unit 10 is started, the driving circuit board 101 is used for sending a power source generation signal to the pump 40 device, and 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 inputs the fluid into the air bag 50 or the air bag through the air outlet 203, and in addition, the three-way valve 201 of the switching device can discharge the fluid to the external atmosphere through the pressure relief outlet 204.
With the design of the present invention, when the control unit 10 sends a forward continuous signal to the switching device 20 to gradually turn the switching device 20 to a fully on state, and in addition, sends a reverse continuous signal to the switching device 20 through the control unit 10 to gradually turn the switching device 20 to a fully off state, the switching device 20 is adjusted in a time-phased manner in cooperation with the fine tuning program 30, and the switching device 20 is adjusted in a time-phased manner at the same time, so as to calculate the average on and/or off time of the switching device 20, and obtain the control interval value of optimal on and/or optimal off.
Through the above operation, the slow start control device of the present embodiment can immediately send the forward signal (off to on) and the reverse signal (on to off) to the switching device 20 through the control unit 10, thereby obtaining the optimized control signal, and avoiding the switching device 20 from generating excessive noise during the repeated cyclic switching of the forward signal and the reverse signal.
Fig. 3 shows a forward continuous signal-on state determination flow in the second embodiment of the present invention.
When the control unit is started, the switching device is firstly utilized to perform opening operation, the opening state of the switching device is adjusted in a time-phased manner in cooperation with the fine tuning program, and the average opening time of the switching device is calculated, at the moment, the system judges whether the switching device gradually reaches the full opening state or not.
If the system judges that the full open state is not reached (reading no), the operation of switching device opening is performed again, otherwise, if the system judges that the full open state is reached (reading yes), the system sets the operation time as the optimal opening control interval value.
Fig. 4 shows a flowchart of a reverse continuous signal-off state determination according to a second embodiment of the present invention.
When the control unit is started, the switching device is firstly utilized to perform closing operation, the closing state of the switching device is adjusted in a time-phased manner in cooperation with the fine tuning program, and the average closing time of the switching device is calculated, at the moment, the system judges whether the switching device gradually reaches the complete closing state or not.
If the system judges that the switching device is not in the completely closed state (reading no), the switching device is restarted, otherwise, if the system judges that the switching device is in the completely closed state (reading yes), the system sets the operation time to be the optimal closing control interval value.
As shown in fig. 5, a test result of the slow start control device according to the second embodiment of the present invention is illustrated. The test environment of the embodiment is to switch the switching device by a three-way valve switching device, wherein the pump device is an air pump, and the test condition of a single air bag is carried out.
The noise value will be as high as 55.6 (Db) when the slow start circuit is not enabled for three-way valve opening, will drop slightly to 53.9 (Db) when the slow start circuit is enabled for three-way valve reverse continuous signal opening, and will drop significantly to 44.6 (Db) when the slow start circuit is enabled for three-way valve forward continuous signal and reverse continuous signal opening.
The comparison of the experimental data shows that the slow start control system of the embodiment can send the forward signal (closed to open) and the reverse signal (open to closed) to the switching device through the control unit, so as to obtain the optimized control signal, and further avoid the excessive noise generated by the switching device in the cycle switching of the repeated forward continuous signal and the reverse continuous signal.
Example III
As shown in fig. 6, a difference compared to the embodiment is that the switching device 20 may be specifically provided with an intelligent control system 21 and a channel 22.
Wherein, the intelligent control system 21 is set with an on mode and an off mode, and the on mode signal is provided by the intelligent control system 21 to gradually turn the switching device 20 from the off state to the optimal on state, and the off mode signal is provided by the intelligent control system 21 to gradually turn the switching device 20 from the on state to the optimal off state.
In the present embodiment, the intelligent control system 21 obtains the optimal opening mode fluid amount and the optimal closing mode fluid amount of the channel 22 through a Pulse Width Modulation (PWM) method.
As shown in fig. 7, a broken line partial position enlargement simulation is illustrated in the third embodiment of the present invention. After the pump 40 generates fluid, the fluid is input into the switching device 20 via the air inlet.
The valve assembly 23 in the switching device 20 determines whether to open or close the channel (by the action of tensile forces on both sides) through the intelligent control system 21, and obtains the optimal opening mode fluid quantity and the optimal closing mode fluid quantity of the channel 22 by using the intelligent control system 21 mode.
Fig. 8 shows an on state judgment flow of the intelligent control system according to the third embodiment of the present invention. When the valve assembly is started by the intelligent control system, the switching device is used for starting, and whether the optimal opening mode fluid quantity is reached is judged by combining a Pulse Width Modulation (PWM) mode.
If the system determines that the optimal open mode fluid volume has not been reached (read no), the valve assembly opening operation will be resumed, whereas if the system determines that the optimal open mode fluid volume has been reached (read yes), the system will set the operation time to open the valve assembly to the optimal open mode fluid volume.
Fig. 9 shows a shutdown state determination flow of the intelligent control system according to the third embodiment of the present invention. When the valve assembly is started by the intelligent control system, the switching device is used for closing, and whether the optimal closing mode fluid quantity is reached is judged by combining a Pulse Width Modulation (PWM) mode.
If the system determines that the optimal closed mode fluid volume has not been reached (read no), the valve assembly closing operation will be resumed, whereas if the system determines that the optimal closed mode fluid volume has been reached (read yes), the system will set this operation time to close the valve assembly to the optimal closed mode fluid volume.
The present invention is not limited to the above-mentioned embodiments, but is not limited to the above-mentioned embodiments, and any simple modification, equivalent changes and modification made to the above-mentioned embodiments according to the technical matters of the present invention can be made by those skilled in the art without departing from the scope of the present invention.
