Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The magnetic suspension set and the pressure ratio dynamic pre-adjusting method and device thereof according to the embodiment of the invention are described below with reference to the accompanying drawings.
Fig. 1 is a flow chart of a magnetic levitation train pressure ratio dynamic pre-adjustment method according to an embodiment of the invention.
As shown in fig. 1, the method for dynamically pre-adjusting the pressure ratio of a magnetic suspension set of the present invention comprises the following steps:
and S1, acquiring the pressure ratio of the head of the magnetic suspension set.
Wherein, the magnetic suspension set can be a magnetic suspension centrifugal water chilling unit.
Specifically, in the operation process of the magnetic suspension unit, the pressure ratio of the magnetic suspension unit can be obtained in real time, or the pressure ratio of the magnetic suspension unit is obtained every other first preset time when the water temperature or the load change is smaller than a certain value, and the pressure ratio of the magnetic suspension unit is obtained every other second preset time when the water temperature or the load change is larger than the certain value, wherein the second preset time is smaller than or equal to the first preset time.
Optionally, when the magnetic levitation train operates, a user can obtain the pressure ratio of the machine head through a remote controller connected with the magnetic levitation train as required so as to check the pressure ratio of the machine head at any time.
And S2, acquiring the dynamic coefficient value according to the pressure ratio of the handpiece.
In one embodiment of the invention, obtaining the dynamic coefficient value from the pressure ratio of the handpiece comprises: judging whether the pressure ratio of the machine head is smaller than a minimum pressure ratio preset value or not; if the value is smaller than the preset value of the minimum pressure ratio, setting the dynamic coefficient value to be 1; if the pressure ratio is not less than the minimum pressure ratio preset value, further judging whether the pressure ratio of the machine head is greater than the maximum pressure ratio preset value; and setting the dynamic coefficient value to a preset minimum value if the value is greater than the maximum pressure ratio preset value.
Specifically, referring to fig. 2 and 3, PR is the pressure ratio of the head, Kpr is the dynamic coefficient value, Kprmin is the preset minimum value, and PRumin and PRumax are the minimum pressure ratio preset value and the maximum pressure ratio preset value, respectively. When PR<When PRumin, Kpr is 1; when PR>When PRumax is obtained, Kpr is Kprmin; when PRumin<PR<When the number of the particles is PRumax,
PR, Kpr, decreases linearly with increasing PR.
And S3, acquiring the operation current value of the handpiece.
In one embodiment of the invention, when the number of the machine heads of the magnetic suspension machine set is multiple, the pressure ratio of the machine heads is the maximum pressure ratio of the multiple machine heads, and the operation current value of the machine heads is the maximum operation current value of the multiple machine heads. Therefore, the magnetic suspension set pressure ratio dynamic adjusting method is ensured to cover all machine heads of the set, and the control of the magnetic suspension set is more accurate.
Of course, when there is one head of the magnetic suspension unit, the pressure ratio of the head is the pressure ratio of the head, and the operation current value of the head is the operation current of the head.
Optionally, the obtained operating current and dynamic coefficient value of the handpiece are displayed to a user through a display screen of the magnetic suspension unit or a remote controller connected with the magnetic suspension unit, so that the user can check the values at any time.
And S4, controlling the magnetic suspension set according to the running current value and the dynamic coefficient value.
In one embodiment of the present invention, referring to fig. 3, controlling the magnetic levitation train according to the operation current value and the dynamic coefficient value comprises: generating a dynamic current load limit value according to the dynamic coefficient value; judging whether the running current value is larger than the dynamic current load limit value or not; and if the current is larger than the dynamic current load limit value, controlling the magnetic suspension set to limit the load.
Further, after controlling the magnetic suspension set to limit the load, the method further comprises the following steps: generating a dynamic current unloading value according to the dynamic coefficient value; judging whether the running current value is larger than the dynamic current unloading value or not; and if the current is larger than the dynamic current unloading value, controlling the magnetic suspension set to unload.
The dynamic current limit value may be PARGmax _1 ═ ARGmax _1 × Kpr, and the dynamic current unload value may be PARGmax _2 ═ ARGmax _2 × Kpr, where ARGmax _1 and ARGmax _2 are the dynamic current limit value and the dynamic current unload value respectively under normal operation of the magnetic levitation set, and the dynamic current unload value is greater than the dynamic current limit value.
Specifically, in the process of operation of the magnetic suspension unit, when the operation current value of the machine head is detected to be larger than the dynamic current load limit value, the magnetic suspension unit is controlled to limit the load, meanwhile, the current magnetic suspension unit can be prompted to need load limit through voice prompt or other prompting modes, namely, the upper limit of the load is reached, the load increase is stopped, whether the operation current value is larger than the dynamic current load relief value or not is judged immediately, if yes, the magnetic suspension unit is controlled to unload, and meanwhile, prompting information can be sent. After unloading, if the running current value is smaller than the dynamic current unloading value, the unloading is stopped, whether the running current value is larger than the dynamic current load limiting value or not is judged again, and the process is repeated.
Therefore, the magnetic suspension unit can not give an alarm and stop running due to overload in the running process, so that the magnetic suspension unit can stably run under the working condition of high pressure ratio, and the service life and the user experience of the magnetic suspension unit are prolonged.
In one example, referring to fig. 3, if the operating current value is not greater than the dynamic current limit value, generating a dynamic current unload exit value as a function of the dynamic coefficient value; judging whether the running current value is smaller than the dynamic current unloading exit value or not; if the current is less than the unloading exit value of the dynamic current, the normal operation of the magnetic suspension set is kept; and if the current is not less than the dynamic current unloading exit value, controlling the magnetic suspension set to unload.
The dynamic current unloading exit value may be PARGmax _3 ═ ARGmax _3 × Kpr, the ARGmax _3 is the dynamic current unloading exit value under normal operation of the magnetic levitation train, and the dynamic current unloading exit value is smaller than the dynamic current load limit value.
Specifically, in the operation process of the magnetic suspension set, if the operation current value is not greater than the dynamic current load limit value, that is, when the increase of the load is not required to be stopped, whether the operation current value is smaller than the dynamic current unloading exit value or not is judged, if so, the magnetic suspension set normally operates and can be adjusted, and if the operation current value is larger than the dynamic current unloading exit value, the magnetic suspension set is controlled to unload, and prompt information can be sent out.
In the example, even if the running current value of the machine head is not greater than the dynamic current load limit value, when the running current value is greater than the dynamic current unloading exit value, the magnetic suspension unit needs to be unloaded, so that the phenomenon of alarm shutdown of the magnetic suspension unit is further reduced, and the magnetic suspension unit can run more stably.
In conclusion, the method for dynamically adjusting the pressure ratio of the magnetic suspension set controls the magnetic suspension set according to the pressure ratio and the running current value of the machine head of the magnetic suspension set in the running process of the magnetic suspension set, can greatly reduce the phenomenon of alarm shutdown of the magnetic suspension set caused by pressure ratio fluctuation, enables the magnetic suspension set to run stably, and improves the service life and user experience of the magnetic suspension set.
Furthermore, the present invention also proposes a computer-readable storage medium, on which a computer program is stored, which, when the program in the storage medium is executed by a processor, enables the magnetic levitation train pressure ratio dynamic pre-adjustment method of the present invention.
When the program corresponding to the dynamic pressure ratio pre-adjusting method of the magnetic suspension set stored on the computer readable storage medium is executed, the phenomenon that the magnetic suspension set generates alarm shutdown can be greatly reduced, and the magnetic suspension set can stably operate.
