and 102, when the voltage is determined not to be matched with the preset voltage range, generating a control instruction, sending the control instruction to a pilot output actuator of the working machine, and controlling a generator output actuator of the working machine to stop outputting electric energy.

The invention provides a control method of a working machine, which comprises the steps of obtaining the voltage of a generator of the working machine in operation; when the acquired voltage is determined to be not matched with the preset voltage range, a control instruction is generated, and the control instruction is sent to a pilot output actuator of the working machine, wherein the control instruction is used for indicating the pilot output actuator to control the pilot assembly to close, and the closing of the pilot assembly is used for indicating the working machine to stop working, therefore, when the voltage is not matched with the preset voltage range, the pilot assembly is automatically closed, the working machine stops working, the working machine is prevented from working abnormally when a generator is abnormal, and the generator output actuator of the working machine is controlled to stop outputting electric energy at the same time, wherein the generator output actuator is used for transmitting the electric energy generated by the generator to the electrical equipment of the working machine, and therefore, the invention cuts off the electric energy transmission between the generator and the electrical equipment, namely, isolates the generator and the electrical equipment, when having avoided the generator to appear unusually, electrical equipment appears damaging, the effectual user experience that has improved.
Wherein, the operation machinery includes: excavators, road rollers, pump trucks, and the like. The following description will be given taking the working machine as an excavator as an example, but it should be noted that the description is given here by way of example only and is not intended to limit the scope of protection. The following examples in the embodiments also do not limit the scope of protection, and are not limited to any one.
Wherein, electrical equipment includes: integrated box, relay, working lamp, alarm lamp, radio, IO module etc..
In one embodiment, before obtaining the voltage of the generator of the operating work machine, the work machine needs to be tested, as shown in fig. 2:
In step 202, a voltage of a generator of the work machine is obtained.
In step 203, the voltage of the work machine level is detected.
In step 204, it is determined whether the voltage level is less than the predetermined voltage level, if so, step 205 is performed, otherwise, step 206 is performed.
At step 205, the work machine is started.
At step 206, the work machine is inhibited from being started.
Before the operation machine is started, the level voltage of the operation machine needs to be detected, and the operation machine is started only when the starting condition is met, so that the safety of the operation machine is ensured, and the condition of the operation machine is avoided.
In one embodiment, when it is determined that the work machine is operating, a corresponding control strategy is employed to control the work machine based on the voltage of the generator and the actual condition of the work machine, as shown in fig. 3:
And step 302, when the voltage is matched with the preset voltage range, judging whether the operation fault exists in the working machine.
The preset voltage range is a range of voltage of the corresponding generator when the working machine can work normally and the electrical equipment can work normally.
Among them, the operation failure is a failure that affects the operation of the working machine.
Wherein the operational failure comprises: a first pressure failure when the engine oil pressure is lower than a preset pressure, an runaway failure when the operating machine has a runaway phenomenon, a fuel failure when the fuel oil is lower than a preset oil amount, a first temperature failure when the cooling water temperature is higher than a preset temperature, a second pressure failure when the tire pressure is lower than a preset tire pressure, a second temperature failure when the Exhaust pipe temperature is higher than a preset temperature, an abnormal waste water circulation failure when an Exhaust Gas Recirculation (EGR) system is abnormal, and the like.
And step 303, controlling the working machine to normally operate when the working machine is determined not to have the operation fault.
In step 304, when it is determined that the work machine has an operational failure, a failure level of the operational failure is determined.
In one embodiment, when it is determined that the work machine has an operational failure, the failure level is determined based on a degree of influence of the operational failure on operation of the work machine.
Wherein the failure levels include: a first failure level, a second failure level, and a third failure level.
For example, a first pressure fault and an aircraft fault may affect the operation of the work machine to a significant extent, causing damage to the work machine and injury to personnel, and thus may be defined as a first fault level. For another example, a fuel fault and a first temperature fault may affect operation of the work machine, but may not damage the work machine and cause injury to personnel, but may not guarantee operation of the work machine for a long period of time, and thus may be defined as a second fault level. For another example, the second pressure failure, the second temperature failure, and the abnormal failure of the waste water circulation may not have any influence on the working machine, and may only cause a reduction in the working efficiency, and thus, may be defined as a third failure level.
At step 305, the work machine is controlled using a control strategy corresponding to the failure level.
In one embodiment, a control strategy corresponding to a fault level is used to control a specific implementation of a work machine as shown in fig. 4:
and step 401, when the fault level is the first fault level, generating a control instruction, and sending the control instruction to the pilot output actuator to control the working machine to stop working.
And step 403, controlling the working machine to normally operate when the fault level is the third fault level.
When the fault level is the first fault level, the pilot output actuator is directly utilized to control the pilot assembly to close, so that the operation of the operation machine is stopped, the damage of the operation machine and the possible personal injury are avoided, and the personal safety is ensured; when the fault level is the second fault level, whether the operation is carried out on the operation machine is judged based on the operation duration of the operation machine, so that the operation of the operation machine is ensured to be carried out as much as possible, and the operation progress is improved; when the fault level is the third fault level, the working machine is continuously controlled to work in order to ensure the working progress because no influence is caused on the working machine and personnel.
In a specific embodiment, when the voltage is determined to be not matched with the preset voltage range, it is determined that the generator is abnormal, at the moment, first alarm information is generated, and the first alarm information is sent to a central control screen of the working machine, so that the central control screen displays the first alarm information.
Wherein, first alarm information is used for instructing the generator to appear unusually.
When the abnormal condition of the generator is determined, the first alarm information is displayed on the central control screen to remind a driver, and at the moment, the driver can also manually control the working machine according to the first alarm information. The invention effectively improves the user experience and ensures the personnel safety.
In one specific embodiment, when the operating fault of the working machine is determined, second alarm information is generated and sent to a central control screen of the working machine, so that the central control screen displays the second alarm information.
The second alarm information is used for indicating the fault level of the operation fault and the actual component with the operation fault.
When the operation fault of the operation machine occurs, the second alarm information is displayed to the central control screen to remind the driver, and at the moment, the driver can also carry out manual control on the operation machine according to the first alarm information. The invention effectively improves the user experience and ensures the personnel safety.
Of course, the sequence of determining whether the voltage of the generator is normal and determining whether the operation fault exists in the working machine is not strictly limited.
