Detailed Description
The scheme of the present application is further described below with reference to the accompanying figures 1 to 5:
the cleaning robot comprises a collision perception sensor 1 for acquiring and perceiving collision conditions in the running process of the robot; a water quantity control module 2 for controlling the water yield; and a controller 3 connected to and controlling the collision sensing sensor 1 and the water amount control module 2; the collision perception sensor 1 comprises an accelerometer, the water quantity control module 2 comprises a water pump, and the controller 3 controls the water outlet speed according to the collision information.
The water outlet control method of the cleaning robot comprises a water outlet control step and an operation duration control step;
firstly, setting judgment time T, standard water outlet speed A under the reference space size X ', and standard operation time T' required by the robot to walk to cover more than 90% of the space; the cleaning robot firstly runs at a standard water outlet speed A for judging time T;
the effluent control step is as follows:
1) acquiring the collision frequency N of the cleaning robot in the judgment time T;
2) when the N is greater than 1, the reaction mixture,
obtaining the size X of the current walking space through a formula X which is 1/lnN;
obtaining a water outlet speed Y through a formula Y-A X/X', and discharging water according to the water outlet speed Y;
the operation is circulated until the operation time t is finished;
3) when N is less than or equal to 1, judging that the cleaning robot is trapped, and closing water outlet;
the smaller the space is, the more the collision times are, the more the machine walks through the repeated area, and accordingly, the water outlet speed is reduced, so that the floor damage is reduced while the cleaning capacity is maintained, and the machine is prevented from skidding;
the operation time length control step is as follows:
1) acquiring the collision frequency N of the cleaning robot in the judgment time T;
2) when the N is greater than 1, the reaction mixture,
obtaining the size X of the current walking space through a formula X which is 1/lnN;
obtaining the operation time length t through a formula t '. X/X';
3) and when N is less than or equal to 1, judging that the cleaning robot is trapped, and transferring to a trapped processing program.
The step of acquiring the judgment time T comprises the following steps: placing the cleaning robot in a reference space to operate, and taking the longest distance L of the reference space; obtaining a judgment time T through a formula T-G L/V; wherein G is a constant, L is the longest distance of the reference space, V is the walking speed of the cleaning robot, in order to ensure that the samples are close to reality, more sample sets are selected as much as possible to serve as the reference, but too many samples cannot be selected, otherwise, the machine covers all the areas, the meaning of water control is lost, and the value of G is 10. For example, the reference space is a rectangle of 3m × 4m, and the traveling speed V of the cleaning robot is 0.3 m/s; i.e. the longest distance L of the reference space is 5m, T is 10 m 5/0.3 166.67 s.
Since the cleaning robot walks randomly in a fixed space, the process is similar to the movement of gas molecules in a space in thermodynamics, and the larger the space is, the smaller the entropy value is, and the smaller the space is, the larger the entropy value is. And comparing the current entropy value with the entropy value of the reference space to judge the size of the current space. Therefore, the step of obtaining the reference space size X' is: placing the cleaning robot in a reference space to operate, and acquiring the number of collision times N0 of the cleaning robot within the judgment time T; according to an evaluation formula S-K lnW of thermodynamic entropy, wherein W is a state number, and K is a Boltzmann constant and is used for expressing the relation between energy and temperature; substituting the value of K into 1 and substituting W into the collision frequency N0 to obtain the spatial entropy S-lnN 0; since entropy is inversely proportional to the reference spatial size, the reference spatial size X' 1/S1/lnN 0.
The standard water outlet speed A is adjusted and set to be a proper value according to the walking condition of the cleaning robot in the reference space, and is ml/min; the standard water exit velocity a is correlated to a reference space size X'.
The step of obtaining the standard operation time t' is as follows: placing the cleaning robot in a reference space to walk, and recording the time required by the cleaning robot to walk to cover more than 90% of the space; multiple sets of time records are obtained through multiple tests, and the average value of the time records is taken as the standard running time t'.
The above preferred embodiments should be considered as examples of the embodiments of the present application, and technical deductions, substitutions, improvements and the like similar to, similar to or based on the embodiments of the present application should be considered as the protection scope of the present patent.
