[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0022] Embodiment 1

[0023] Embodiment 1 of the present invention provides an inflation control method for an inflator. Figure 1 It is a schematic flow chart of the inflation control method of the inflator in Embodiment 1 of the present invention, asFigure 1 As shown in the figure, the inflation control method of the air pump in Embodiment 1 of the present invention includes the following steps:

[0024] S101: During the current inflation process of the air pump for the item to be inflated, obtain the current inflation pressure of the air pump.

[0025] Specifically, a pressure sensor is installed at the inflation pipe of the air pump, and the current inflation pressure of the air pump can be obtained through the pressure sensor.

[0026] Exemplarily, the item to be inflated can be a car tire, a motorcycle tire, a bicycle tire, a basketball, a football, etc.

[0027] S102: Determine the stop pressure when the air pump inflates the item to be inflated according to the historical inflation data of the air pump inflating the item to be inflated.

[0028] Specifically, the method of determining the stop pressure when the air pump inflates the item to be inflated according to the historical inflation data of the air pump inflating the item to be inflated can be as follows: Input the historical inflation data of the air pump inflating the item to be inflated into a preset pressure compensation model to obtain the stop pressure when the air pump inflates the item to be inflated.

[0029] Specifically, the historical inflation data includes multiple groups of inflation data of the air pump inflating the item to be inflated, and one group of inflation data of the air pump inflating the item to be inflated includes: the starting pressure of the item to be inflated at the starting moment of inflation, the termination pressure of the item to be inflated at the end moment of inflation, the inflation duration, the accuracy of the pressure sensor of the air pump, and the stop pressure when the air pump stops inflating.

[0030] Before determining the stop pressure when the air pump inflates the item to be inflated according to the historical inflation data of the air pump inflating the item to be inflated, it further includes: obtaining the number of times the air pump inflates the item to be inflated; when the number is greater than or equal to a preset quantity threshold, execute the step of determining the stop pressure when the air pump inflates the item to be inflated according to the historical inflation data of the air pump inflating the item to be inflated.

[0031] When the number is less than the quantity threshold, determine the stop pressure according to the original control program in the air pump. For example, determine the stop pressure according to the inflation mode.

[0032] In Embodiment 1 of the present invention, the stop pressure when the air pump stops inflating can be set by the user, can be matched by the air inflation control system of the air pump according to the item to be inflated, or can be determined according to historical inflation data. Specifically, the air pump can also perform mode selection. Different modes can represent different items to be inflated, and the stop pressure is different in different modes, so that different items to be inflated correspond to different stop pressures. For example, during the first inflation process or the first few inflation processes (such as the first 5 times) when the air pump inflates the item to be inflated, the stop pressure when the air pump stops inflating can be set by the user or matched by the air inflation control system of the air pump according to the type of the item to be inflated. This is because there is no historical inflation data or the historical inflation data is relatively small when the air pump inflates the item to be inflated, so the stop pressure cannot be determined according to the historical inflation data or the stop pressure determined according to the historical inflation data is not accurate.

[0033] During the subsequent inflation processes (other inflation processes except the first inflation process or the first few inflation processes) when the air pump inflates the item to be inflated, the stop pressure when the air pump stops inflating is determined according to historical inflation data. For example, the stop pressure in the 100th inflation process when the air pump inflates the item to be inflated can be obtained according to the inflation data of the inflation processes before the 100th inflation process. It should be noted that the inflation processes before the 100th inflation process can be all the inflation processes from 1 to 99 or some of the inflation processes from 1 to 99.

[0034] Specifically, the pressure compensation model is a BP neural network model.

[0035] A BP neural network is a multi-layer feedforward neural network trained according to the error backpropagation algorithm. It solves the problem of learning the connection weights of the network hidden layer, has excellent multi-dimensional function mapping ability, and has unique advantages in dealing with non-linear problems. In theory, a BP neural network can use an input vector and a corresponding output vector to train a network to approximate a certain function and realize any non-linear mapping from input to output. Generally, the accuracy of the network model is improved by adjusting the number of hidden layers or nodes.

[0036] Figure 2 As a typical BP neural network topology structure, it includes an input layer, a hidden layer, and an output layer. Assume that X is the input vector; H is the output vector of the hidden layer; Y is the output vector of the output layer; D is the expected output vector; V and W are the weight matrices of the input layer - hidden layer and the hidden layer - output layer respectively. Among them, Vj is the weight vector of the jth neuron in the hidden layer, and Wk is the weight vector of the kth neuron in the output layer.

[0037] S103: When the current inflation pressure reaches the stop pressure, control the air pump to stop inflating.

[0038] Further, after controlling the inflation pump to stop inflating, it further includes: obtaining a set of inflation data corresponding to the current inflation process of the inflation pump for the item to be inflated, and adding it to the historical inflation data. That is, adding the inflation data of the current inflation process to the historical inflation data, which can make the historical inflation data increase with the increase in the number of inflations, and further make the stop pressure obtained from the historical inflation data more accurate.

[0039] As Figure 4 shown, the more times it runs, the more data is collected, and the better the calibration effect of the pressure measurement of the inflation pump. The user can adjust the pressure value P setting by observing the tire pressure value of the vehicle-mounted terminal to achieve the effect of artificially adjusting the tire state. There is an upper limit tire pressure value to prevent the stop working pressure value set by the user from being too large.

[0040] Further, after determining the stop pressure when the inflation pump inflates the item to be inflated according to the historical inflation data of the inflation pump for the item to be inflated, it further includes: displaying the stop pressure; determining whether a change instruction for the stop pressure is obtained; when receiving the change instruction for the stop pressure, changing the stop pressure according to the change instruction. Specifically, the change instruction for the stop pressure can be that the user determines whether to modify according to their own experience to judge whether the pressure of the item to be inflated is too large or too small; or it can also revise a pressure threshold according to the real-time pressure value of the item to be inflated. Therefore, the step of changing the stop pressure is added here. It should be noted that when changing the stop pressure according to the change instruction, the number of inflations needs to be cleared.

[0041] To illustrate in detail the inflation control method of the inflation pump in Embodiment 1 of the present invention, a specific example is given. As Figure 3 shown, the inflation control method of the inflation pump includes the following steps:

[0042] 1. The user selects an inflation mode and determines the stop pressure according to the selected inflation mode, that is, P 阈值 ; if a setting of the stop pressure by the user is received, then obtain P 设置 , if a setting of the stop pressure by the user is not received, then directly use the P 阈值 determined according to the inflation mode as the stop pressure;

[0043] 2. Obtain the number of inflations recorded in the memory. When the number of inflations is less than 5 times, regardless of whether P 设置 is received, directly use the P 阈值 determined according to the inflation mode as the stop pressure, and go to step 3; when the number of inflations is greater than or equal to 5 times, determine whether there is P设置 , when it exists, judge P 设置 whether it is greater than the maximum stop pressure. When P 设置 is greater than the maximum stop pressure, then continue to use P determined according to the inflation mode 阈值 as the stop pressure; when P 设置 is less than or equal to the maximum stop pressure, use P 设置 as the stop pressure; it should be noted that when using P 设置 as the stop pressure, the inflation times need to be cleared to zero;

[0044] 3. Test the tire pressure value P 测量 ;

[0045] 4. When P 测量 = stop pressure (P 阈值 or P 设置 ), the motor stops working; otherwise, continue to detect the tire pressure value P 测量 ;

[0046] 5. Obtain the initial pressure P 起始 of the tire at the start of inflation, the final pressure P 终止 of the tire at the end of inflation, the inflation duration, the accuracy of the inflation pump pressure sensor, and the stop pressure when the inflation pump stops inflating. At the same time, increment the inflation times by 1 and record it in the memory;

[0047] 6. Obtain the inflation times in this inflation mode. When the inflation times are greater than or equal to 5 times, input the data saved in the memory into the pressure measurement compensation model P = f(P 起始 , P 终止 , t, I P , P 设置 ) to obtain the next stop pressure of the tire in this mode, that is, P 阈值 .

[0048] Thus, it can be seen that the inflation control method of the inflation pump provided in Embodiment 1 of the present invention obtains the initial pressure value P 起始 of the tire of the inflation pump pressure sensor each time, the stop working pressure value P 终止 , the user - set final pressure value P 设置 of the tire, the inflation time t, the self - accuracy I P of the inflation pump pressure sensor, and establishes a pressure measurement compensation model of the inflation pump pressure sensor, P = f(P 起始 , P 终止 , t, I P , P 设置 ). Through continuous feedback adjustment and learning prediction, measurement compensation is performed when measuring the tire pressure with the inflation pump sensor next time, improving the tire inflation efficiency and user usage safety.
