and S101, detecting the pressure of the outlet of the hydraulic oil pump.
The hydraulic oil pump can work only by being driven by the motor, and meanwhile, the hydraulic oil pump is equipment for driving the crane to get on the vehicle to act, so that whether the crane gets on the vehicle to act or not can be judged by detecting the pressure of the outlet of the hydraulic oil pump, and the crane is also judged to be in a hanging load mode or a running mode.

S103, timing the working time of the engine when the crane is in different working modes.
After the current working mode of the crane is determined in step S102, the working time of the engine when the crane is in different working modes may be respectively counted.
Specifically, when the pressure of an outlet of a hydraulic oil pump is larger than zero, the crane is judged to be in a suspension mode, the working time of an engine when the crane is in the suspension mode is timed, and the timing result is determined as the first working time of the engine when the crane is in the suspension mode; and when the pressure of the outlet of the hydraulic oil pump is equal to zero, judging that the crane is in a running mode, timing the working time of the engine when the crane is in the running mode, and determining the timing result as the second working time of the engine when the crane is in the running mode.
Furthermore, one of the hoisting mode and the traveling mode of the crane may be timed, and the difference between the total operating time of the engine of the crane and the engine operating time of the timed operating mode may be used as the operating time of the engine of the other operating mode, where the total operating time of the engine of the crane may be directly read from the engine ECU or obtained in other manners.
For example, only the engine operating time period when the crane is in the suspended load mode is timed, and the difference value between the total engine operating time period of the crane and the engine operating time period when the crane is in the suspended load mode is used as the engine operating time period when the crane is in the driving mode.
Preferably, the method for monitoring the operation duration of the crane further comprises: acquiring the engine speed of the crane; and timing the working time of the engine when the rotating speed of the engine of the crane is greater than the idle speed value, and determining the timing result as the total working time of the engine of the crane. The idle speed value is a minimum engine speed at which the engine is maintained to rotate.
The following describes a method for monitoring the operating time of an engine when a crane is in different operating states, i.e., a suspended load mode and a traveling mode.
When the crane is in a running mode, the speed of the crane is acquired, the crane is determined to be in a running state or a stopping state according to whether the speed of the crane is greater than zero, and the working time of an engine of the crane in the running state or the stopping state is correspondingly timed.

Here, a minimum vehicle speed set value for keeping the vehicle moving forward or backward may be set, and it may be determined that the crane is in the travel mode when the vehicle speed is greater than the minimum vehicle speed set value.
When the crane is in a hoisting mode, acquiring the hoisting weight of the crane; according to the relation between the hoisting load weight of the crane and the empty hook weight of the crane, determining that the crane is in a hoisting mode loaded state or an empty hook state, and correspondingly timing the working time of the engine of the crane in the loaded state or the empty hook state.
Preferably, when the hoisting load weight of the crane is greater than the weight of the empty hook, the crane is determined to be in a hoisting mode and in a loading state; and otherwise, determining that the crane is in a hoisting mode and in an empty hook state, wherein the empty hook state means that the crane is in the hoisting mode but is not subjected to hoisting, the weight of an empty hook is determined when the crane is designed, and the weight of the empty hook of each crane or each model of crane is different.
Furthermore, when the crane is in a loaded state or an empty hook state, whether the crane gets on the train or not is further determined according to the magnitude relation between the pressure of the outlet of the hydraulic oil pump and a pressure set value, and the working time of the engine when the crane is in any one of the following states is timed: the device comprises a loading state, a loading state and no action, an idle state and no action.
For example, when the crane is in a loaded state, the pressure of the outlet of the hydraulic oil pump is greater than a pressure set value, it is indicated that the crane gets on the vehicle and acts, it is determined that the crane is in the loaded state and acts, and the working time of the engine in which the crane is in the loaded state and acts is counted.
Fig. 4 is a flowchart of an application example of the method for monitoring the operation duration of the crane according to the embodiment of the present invention. As shown in fig. 4, firstly, it is determined that the crane is working under the condition that the rotation speed of the engine is greater than or equal to the idle speed value, secondly, it is determined that the crane is in the running mode or the suspended load mode according to whether the pressure of the outlet of the hydraulic oil pump is greater than zero, the working time length of the engine when the crane is in the running mode is timed, and the difference value between the total working time length of the engine and the working time length of the engine when the crane is in the running mode is used as the working time length of the engine when the crane is in the suspended load mode.
When the crane is in a running mode and the vehicle speed is equal to zero, judging that the crane is in a running mode stop state, timing the working time of an engine of which the crane is in the running mode stop state, and taking the difference value between the working time of the engine of which the crane is in the running mode and the working time of the engine of which the crane is in the running mode stop state as the working time of the engine of which the crane is in a running mode advancing state.
When the crane is in a hanging mode and the hanging weight is larger than the weight of the empty hook, judging that the crane is in a hanging mode loaded state, timing the working time of an engine of the crane in the hanging mode loaded state, and taking the difference value of the working time of the engine of the crane in the hanging mode and the working time of the engine of the hanging mode loaded state as the working time of the engine of the crane in the hanging mode empty hook state.
Further, when the crane is in a loaded state and the pressure of the outlet of the hydraulic oil pump is smaller than or equal to a pressure set value Pp, judging that the crane is in the loaded state and does not act, timing the working time of the engine of the crane in the loaded state and does not act, and taking the difference value of the working time of the engine of the crane in the loaded state and the working time of the engine of the crane in the loaded state as the working time of the engine of the crane in the loaded state and acts. When the crane is in the idle load state, the same method can be adopted to time and calculate the working time of the engine when the crane is in the idle load action state and the idle load no action state.
It should be noted that the process of timing the operation time of the engine of the crane is performed on the basis that the engine of the crane is in an operating state, for example: the method comprises the steps of determining that the crane is in a running mode when the pressure of a hydraulic oil pump is equal to zero, timing the working time of an engine of which the crane is in the running mode, determining that the crane is in a stop state of the running mode when the speed of the engine is equal to zero, and the like.
Whether the crane acts or not in the hoisting mode can be judged according to detection results of a boom extension sensor, a rotary table rotation sensor, a winch rotation sensor and a boom pitching sensor of the crane, wherein the crane is determined to act if one of the sensors acts. Meanwhile, whether the telescopic action, the rotary table rotation action, the winch rotation action or the lifting arm pitching action of the lifting arm is executed when the crane is in a lifting mode loaded state and an empty hook state can be respectively determined according to the detection result of the sensor, and the working time of the engine when the crane executes one of the actions is correspondingly timed.
The timing of the working time of the engine of the crane in the scheme is suitable for a single-engine crane, for a double-engine crane, the total working time of the engine of the crane can be obtained only by adding the working time of the engine on the crane and the working time of the engine on the chassis, the working time of the engine when the crane is in a hoisting mode is the working time of the engine on the crane, and the working time of the engine when the crane is in a running mode is the working time of the engine on the chassis.
Through the technical scheme, the control device judges the running mode and the suspended load mode of the crane according to the pressure value of the hydraulic oil pump outlet of the crane detected by the detection device, and times the working time of the engine when the crane is in different working modes, the judgment method is simple, the timing result is accurate, and the calculated crane working efficiency is more accurate.
In addition, in the embodiment of the invention, the running mode of the crane is divided into the running state and the stopping state according to the vehicle speed, the hanging load mode is divided into the loading state and the empty hook state according to the hanging load weight, and whether the crane acts or not is judged according to the pressure of the outlet of the hydraulic oil pump, so that the working state of the crane is divided more finely, and the analysis of factors influencing the crane efficiency after the crane efficiency is calculated is facilitated.
