Detailed Description
The invention is described in further detail below with reference to the accompanying examples.
As shown in fig. 1, the method for controlling the safe opening of the steam box in the embodiment is used for a steam box with a handle, wherein pressure sensors are arranged on the upper side and the lower side of the handle, and specifically, the method for controlling the safe opening of the steam box comprises the following steps 1 to 6:
step 1, respectively and simultaneously acquiring pressure data of the upper side of a handle and pressure data of the lower side of the handle, and turning to step 2;
in step 1, the embodiment simultaneously acquires pressure data on the upper side of the handle and pressure data on the lower side of the handle according to the same preset acquisition frequency; that is, pressure data on the upper side of the handle and pressure data on the lower side of the handle are acquired at the same time, and the pressure data on the upper side and the pressure data on the lower side of the handle are in one-to-one correspondence;
step 2, when the upper side and the lower side of the handle have pressure data, which indicates that a user holds the handle at the moment, the step 3 is carried out; otherwise, the user does not touch the handle at the moment, or no user holds the handle, and the steam box is forbidden to be opened at the moment;
step 3, respectively and correspondingly constructing an upper handle side pressure database and a lower handle side pressure database according to the acquired upper handle side pressure data and lower handle side pressure data;
step 4, presetting a first preset fluctuation range aiming at the pressure data on the upper side of the handle and a second preset fluctuation range aiming at the pressure data on the lower side of the handle; in the embodiment, the first preset fluctuation range is the same as the second preset fluctuation range; of course, according to the requirement, the adjustment of the first preset fluctuation range and the second preset fluctuation range by the user can be received so as to meet the requirement of opening the steam box under the actual situation of the user; for example, the user may set the first preset fluctuation range to be different from the second preset fluctuation range;
step 5, when the fluctuation value of the pressure data in the pressure database at the upper side of the handle is in a first preset fluctuation range and the fluctuation value of the pressure data in the pressure database at the lower side of the handle is in a second preset fluctuation range, indicating that the pressure applied to the upper side and the lower side of the handle is in a normal user holding state, and then turning to step 6; otherwise, judging that the handle is operated by mistake currently, and forbidding opening the steam box;
specifically, in the present embodiment, the fluctuation value of the pressure data in the handle upper side pressure database is the variance of the handle upper side pressure database; correspondingly, the fluctuation value of the pressure data in the handle lower side pressure database is the variance of the handle lower side pressure database;
step 6, when the pressure data of the upper side of the handle is larger than the pressure data of the lower side of the handle, indicating that the arm of the current user is lower than the height of the handle, judging that the current user holding the handle is a child, and forbidding opening the steam box; otherwise, the arm of the current user is higher than the height of the handle, so that the user holding the handle is judged to be an adult, and the steam box is allowed to be opened.
In order to more accurately determine that the current user is indeed ready to open the steam box by holding the handle, in this embodiment, when the duration of the pressure applied to the upper side of the handle reaches a first preset time or the duration of the pressure applied to the lower side of the handle reaches a second preset time, the step 2 is performed to finally perform the judgment that the user identity is an adult or a child; otherwise, it indicates that the current user is most likely not to touch the handle of the steam box, and the current user has no intention to open the steam box, in which case opening of the steam box is prohibited.
Certainly, in this embodiment, after the steam box is allowed to be opened, the judgment can be performed to know that when the temperature in the steam box reaches the preset warning value, the steam box starts to discharge pressure and cool down, so that the user is prevented from being scalded by high-temperature steam in the steam box after the steam box is opened.
In addition, when the acceleration value of the pressure on the upper side of the handle is detected to be larger than a first preset acceleration threshold value, the fact that a user applies a large pulling force to the handle of the steam box instantly indicates that the steam box is damaged at the moment, and therefore the steps 1 to 6 are executed after the steam box is delayed for a preset time period, so that the steam box is ensured not to be damaged by instant force of the user; otherwise, the steam box can execute the steps 1 to 6. The preset time period corresponding to the delay of the steam box can be set according to the needs of users, and can also be set by manufacturers of the steam boxes according to a large amount of empirical data.
In order to avoid the adverse effect of external vibration on the normal opening of the steam box, in the embodiment, when the steam box detects the occurrence of vibration exceeding the preset vibration amplitude, the steam box immediately prohibits the external opening of the steam box.
In actual user groups, there are also adult users with small statures, which have small statures but have palms holding things with a much larger holding force than children. Therefore, in order to meet the practical requirements of the steam box for the adult users with short statures, the embodiment can be further improved as follows: when the pressure data of the upper side of the handle is larger than the pressure data of the lower side of the handle and the pressure value of the holding force of the user borne by the upper side of the handle is smaller than a preset holding force pressure threshold value, judging that the user holding the handle is a child at present, and forbidding opening the steam box; otherwise, the current user holding the handle is judged to be an adult, namely the current user is an adult with a short stature, and the steam box is allowed to be opened, so that the adult group with a short identity is more accurately taken care of, and the method is more humanized.
In particular, for the steam box in the embodiment, the handle on the steam box can be arranged between 1.19 and 1.21 meters higher than the ground where the steam box is located, so that the handle position of the steam box is slightly lower than the arm height of an adult with normal height.
Although preferred embodiments of the present invention have been described in detail hereinabove, it should be clearly understood that modifications and variations of the present invention are possible to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
