The process of acquiring V0, V1, V2, V3, and V4 in advance is as follows: obtaining the wind speed value V0={a, b} corresponding to different output currents I0={A, B} when the glass-wiping robot is stationary on the smooth glass, wherein a is the corresponding wind speed when the glass-washing robot is adsorbed on the glass without falling, and b is the maximum wind speed corresponding to the continuous increase of the current under the premise that the glass-cleaning robot can be adsorbed on the glass, and A corresponds to the wind speed of a.

Where b=c, d=e, f=g, h=j, B<D<F<H<K.
由于V0、V1、V2、V3、V4为依次连续增大的区间段,且分别唯一对应不同的电流区间。将第一风速传感器的第三风速值与第二风速传感器的第四风速值分别与预先获得的V0、V1、V2、V3、V4五个风速区间进行比对,并判断第三风速值与第四风速值各自所在的风速区间,以得到第一吸附转盘当前的运动状态、玻璃表面状态、与第三风速值所在的风速区间相对应的第三电流区间、第二吸附转盘当前的运动状态、玻璃表面状态、以及与第四风速值所在的风速区间相对应的第四电流区间。如获得的第三风速值位于风速区间V1内,第四风速值位于风速区间V2内,则可以得到当前第一吸附转盘的状态及玻璃表面的状态为在光滑玻璃表面行进,当前第二吸附转盘的状态及玻璃表面的状态为在凹凸不平玻璃表面静止,依据第一吸附转盘和第二吸附转盘的运动状态和玻璃表面的状态就可以判断擦玻璃机器人的运动状态,且V1唯一对应电流区间I1={C,D},V2唯一对应电流区间I2={E,F},即第三电流区间为I1={C,D},第四电流区间为I2={E,F}。Since V0, V1, V2, V3, and V4 are interval segments that continuously increase in sequence, and each uniquely corresponds to a different current interval. Comparing the third wind speed value of the first wind speed sensor and the fourth wind speed value of the second wind speed sensor with the five wind speed ranges of V0, V1, V2, V3, and V4 obtained in advance, and determining the third wind speed value and the first The wind speed interval in which the four wind speed values are respectively is obtained to obtain the current motion state of the first adsorption turntable, the glass surface state, the third current interval corresponding to the wind speed interval where the third wind speed value is located, the current motion state of the second adsorption turntable, The surface state of the glass and the fourth current interval corresponding to the wind speed interval in which the fourth wind speed value is located. If the obtained third wind speed value is located in the wind speed interval V1, and the fourth wind speed value is located in the wind speed interval V2, the state of the current first adsorption turntable and the state of the glass surface are obtained to travel on the smooth glass surface, and the current second adsorption turntable The state of the glass surface and the state of the glass surface are static on the surface of the uneven glass, and the motion state of the glass-cleaning robot can be judged according to the motion state of the first adsorption turntable and the second adsorption turntable and the state of the glass surface, and the V1 unique corresponding current interval I1 ={C,D}, V2 uniquely corresponds to the current interval I2={E,F}, that is, the third current interval is I1={C, D}, and the fourth current interval is I2={E,F}.
S104:将第三电流区间和第四电流区间的最大电流值进行比较,并将两者中较大的电流值对应的电流区间作为目标电流区间。具体地,根据步骤S103中得到的第三电流区间为I1={C,D}和第四电流区间为I2={E,F},将第三电流区间的电流最大值D与第四电流区间的电流最大值F进行比较,并将D与F中较大的电流值对应的电流区间作为目标电流区间。在本实施例中,F>D,故将第四电流区间作为目标电流区间。S104: Compare the maximum current value of the third current interval and the fourth current interval, and use a current interval corresponding to the larger current value of the two as the target current interval. Specifically, according to the third current interval obtained in step S103, I1={C, D} and the fourth current interval is I2={E, F}, and the current maximum value D and the fourth current interval of the third current interval are The current maximum value F is compared, and the current interval corresponding to the larger current value of D and F is taken as the target current interval. In the present embodiment, F>D, so the fourth current interval is taken as the target current interval.
S105:将第一输出电流调整到目标电流区间范围内,以供给第一吸附转盘和第二吸附转盘在当前状态下所需的吸附力。具体地,根据步骤S104获取的目标电流区间,将风机的第一输出电流调整到目标电流区间内。如在本实施例中,将风机的第一输出电流调整到I2={E,F}之间,以防止擦玻璃机器人因吸附力不足出现掉落的情形,且这种动态调整风机输出电流的过程实时更新,以保证擦玻璃机器人在不同状态下能够自动调整风机输出电流来供给其在不同状态下的吸附力需求。该方法10不仅能够通过第一风速传感器和第二风速传感器的值来判断擦玻璃机器人在玻璃表面上的状态从而对不正常状态进行预警,而且能够通过调节风机的输出电流来加大机器人在不正常状态下的吸附力,具有自动处理不正常状态下的吸附力需求。如当擦玻璃机器人在光滑玻璃表面上行进时,根据读取到的风速值来调节风机的输出电流,使擦玻璃机器人既能在玻璃上无障碍行进,又能稳固地吸附在玻璃表面上。又如当擦玻璃机器人在凹凸不平玻璃表面行进时,如遇到凹凸不平的障碍物或者较大的赃物等,通过加大风机的输出电流,进而使擦玻璃机器人的吸附力更强。当擦玻璃机器人行进到玻璃边沿时,风机的输出电流自动变大以加大擦玻璃机器人的吸附力,然后根据两个风速传感器中风速值的大小判断行进到玻璃边沿的吸附转盘,并且通过控制该吸附转盘返回到玻璃内部。当在大电流下风速传感器的风速值与正常的输出电流的情况下增加不明显时,表示擦玻璃机器人已经回到正常的状态,电流会自动减小到正常状态下的值。S105: Adjust the first output current to the target current interval range to supply the adsorption force required by the first adsorption turntable and the second adsorption turntable in the current state. Specifically, the first output current of the fan is adjusted to the target current interval according to the target current interval acquired in step S104. As in the embodiment, the first output current of the fan is adjusted to be between I2={E, F} to prevent the glass-scraping robot from falling due to insufficient adsorption force, and the dynamic adjustment of the fan output current is The process is updated in real time to ensure that the glass-cleaning robot can automatically adjust the fan output current under different conditions to supply its adsorption force requirements under different conditions. The method 10 can not only judge the state of the glass-cleaning robot on the glass surface by the values of the first wind speed sensor and the second wind speed sensor, thereby warning the abnormal state, and can increase the robot's output current by adjusting the output current of the fan. The adsorption force under normal conditions has the need to automatically handle the adsorption force under abnormal conditions. For example, when the glass-wiping robot travels on the smooth glass surface, the output current of the fan is adjusted according to the read wind speed value, so that the glass-cleaning robot can travel unobstructed on the glass and can be stably adsorbed on the glass surface. For example, when the glass-wiping robot travels on the surface of the uneven glass, if an uneven obstacle or a large object is encountered, the output current of the fan is increased, and the suction force of the glass-cleaning robot is further enhanced. When the glass-wiping robot travels to the edge of the glass, the output current of the fan automatically increases to increase the adsorption force of the glass-cleaning robot, and then the adsorption turntable that travels to the edge of the glass is judged according to the magnitude of the wind speed value of the two wind speed sensors, and is controlled by The adsorption carousel returns to the inside of the glass. When the wind speed value of the wind speed sensor is not significantly increased under the condition of the high current, the glass-cleaning robot has returned to the normal state, and the current is automatically reduced to the value under the normal state.
