Fig. 1 is a flowchart of a control method of an excavator according to an embodiment of the present application. The control method of the excavator comprises the following steps:
s101: and after receiving the opening instruction, acquiring the heart rate value of the driver for a preset number of times.
In this step, before the excavator is prepared to be opened to the driver, dispose intelligent wearing equipment on one's body at the driver first, so that gather driver's heart rate value in real time, wherein intelligent wearing equipment includes intelligent wrist-watch, intelligent bracelet, intelligent glasses, intelligent dress etc. can gather human physiological parameter's smart machine, after wearing good smart machine, open the excavator, the main control unit of excavator is after receiving the instruction of opening, gather driver's heart rate value once every period through intelligent wearing equipment in the preset time, and send main control unit, until the driver's heart rate value of taking the preset number of times.

It should be noted that, the information transmission between the intelligent wearable device and the main controller may be transmitted in a bluetooth manner, or may be transmitted in other wireless transmission manners, which is not limited herein.
S102: and determining the current target heart rate grade of the driver according to the heart rate value of the driver of the preset times and the basic information of the driver.
In the step, basic information of a driver is obtained, wherein the basic information of the driver comprises basic information of the sex, age, weight and the like of the driver, which influence the normal heart rate of a human body, standard heart rate values and various heart rate levels matched with the basic information of the driver are screened out according to the obtained basic information of the driver, and then the heart rate level to which the driver belongs currently is determined according to the obtained heart rate values of the driver for preset times, namely the target heart rate level.
The standard heart rate value is matched with the basic information of the driver, and the standard heart rate value of the normal human body is closely related to the sex, the age and the weight of the driver, so that the standard heart rate value corresponding to the basic information of the driver can be matched after the basic information of the driver is obtained.
In one example, assuming that the sex of the driver is male, the age is 25 years, and the weight is 130 jin, the standard heart rate value corresponding to the driver is matched according to the sex of the driver being male, the age being 25 years, and the weight being 130 jin, which are screened one by one.
S103: determining a control strategy matching the target heart rate rating.
In this step, the control strategy corresponding to each heart rate level is stored in advance, so that after the target heart rate level of the driver is determined, the control strategy corresponding to the target heart rate level is acquired, and the control strategy is determined to be the control strategy matched with the target heart rate level.
The heart rate grade is divided into a safety grade and a danger grade, the safety grade is divided into a high safety grade and a normal safety grade, the danger grade is divided into a low danger grade and a high danger grade, and different control strategies are formulated according to different heart rate grades.
S104: and controlling the driving device according to the control strategy.
In the step, the driving device of the excavator is controlled according to the determined control strategy, wherein the driving device of the excavator comprises an engine of the excavator, a hydraulic pump of the excavator and a display screen of a cab of the excavator.

In the embodiment of the application, after the starting instruction is received, the heart rate value of the driver for the preset times is obtained, the target heart rate grade to which the driver belongs currently is determined according to the heart rate value of the driver for the preset times and basic information of the driver, then the control strategy matched with the target heart rate grade is determined according to the determined target heart rate grade, and the driving device of the excavator is controlled according to the control strategy. According to the method and the device, the current target heart rate grade of the driver is determined, so that the current physical condition of the driver is determined, the driving device of the excavator is controlled according to the current physical condition of the driver, and the safety of operating and driving the excavator can be improved.
In a possible implementation manner, in S102, the determining, according to the heart rate value of the driver of the preset number of times and the basic information of the driver, a target heart rate level to which the driver currently belongs includes the following steps:
step (1): and determining each heart rate interval matched with the basic information and the heart rate grade associated with each heart rate interval according to the basic information of the driver.
In the step, according to basic information such as sex, age and weight of the driver, a standard heart rate value matched with the basic information of the driver and each heart rate interval are determined, and each heart rate interval is associated with a heart rate grade, namely a safety grade or a danger grade.
The heart rate intervals represent the physical conditions of the driver, the heart rate intervals 80-82 or 87-89 are specified to be normal safety levels if the basic heart rate value matched with the basic information of the driver is 85, and the heart rate intervals of the driver are determined to be 87-89 if the real-time heart rate value of the driver is 88, namely the physical conditions of the driver are normal safety.
Step (2): and calculating the average heart rate value of the driver according to the heart rate value of the driver of the preset times.
In this step, for the heart rate value of the driver which has acquired the preset number of times of the driver, a value obtained by dividing the total heart rate value within the calculated preset number of times by the preset number of times is determined as the average heart rate value of the driver.
In one example, if the preset number is 5, and the values of the heart rate of the driver at the 5 times are 85, 87, 82, 90 and 86 respectively, the total value of the heart rate of the 5 sets is 85+87+82+90+86 which is 430, so that the average value of the heart rate of the driver is 430/5-86.
And (3): and determining a heart rate interval to which the average heart rate value belongs, and determining a heart rate grade associated with the heart rate interval as the target heart rate grade.
In the step, the calculated average heart rate value of the driver is compared with the determined heart rate intervals, the heart rate interval to which the average heart rate value of the driver belongs is determined, and the heart rate grade associated with the heart rate interval is determined as the target heart rate grade to which the driver belongs.
In a possible embodiment, each heart rate interval comprises a lower limit value and an upper limit value, the lower limit value being calculated by the following formula:
y1＝a-a*x％；
wherein y1 represents a lower limit value of each heart rate interval, a represents a standard heart rate value corresponding to the basic information, and x represents a preset percentage corresponding to the heart rate interval;

wherein y2 represents an upper limit value of each heart rate interval, a represents a standard heart rate value corresponding to the basic information, and x represents a preset percentage corresponding to the heart rate interval.
Further, different basic information corresponds to different standard heart rate values and different heart rate intervals, wherein an upper limit value and a lower limit value corresponding to each heart rate interval are obtained through the standard heart rate value corresponding to the basic information and a preset percentage.
