The invention discloses a load spectrum compilation method of an engineering vehicle, electronic equipment and a readable storage medium. The method comprises the following steps: acquiring driving information of the engineering vehicle under different working conditions in at least one working cycle; the working cycle refers to a process from execution of one-time transportation to end of the transportation; the driving information at least comprises a driving speed; according to the driving information and the vehicle information of the engineering vehicle, the rotating speed of a power input shaft of the engineering vehicle under different working conditions in all the working cycles and the duration and the use frequency corresponding to the different working conditions in all the working cycles are obtained; acquiring torques of the power input shaft under different working conditions in each working cycle; and determining a load spectrum of the engineering vehicle based on the rotating speed, the torque, the driving speed, the duration and the use frequency. Therefore, the load spectrum of the engineering vehicle can be conveniently compiled, and the compilation efficiency and applicability of the load spectrum of the engineering vehicle are improved.

The application discloses a rule engine execution method, device and equipment and a computer readable storage medium. The application assembles a rule instance object structure value according to preset rule parameter classes, obtains a target condition object instance, constructs a hash key value according to the target condition object instance and a fixed query condition array, constructs a combined key value according to the target condition object instance, a dynamic query condition array and a classification combination condition array, and obtains a rule result from the rule engine according to the hash key value and the combined key value. The application processes rule conditions based on the rule engine, separates business logic from code, and thus simplifies development of business code.
