Problems solved by technology

On the one hand, due to space constraints, some parts cannot be designed redundantly; on the other hand, the cost of the whole machine is greatly increased
Most of the existing excavators are not equipped with motion state monitoring devices, and the driving is mainly driven by the operator's own judgment, which has high requirements for the driver. When there is a malfunction, the inertia of large equipment and the delay caused by the response time, it is easy to cause security incident

Embodiment 1

[0024] In the technical solutions disclosed in one or more embodiments, such as figure 1 As shown, an excavator action state monitoring device includes a main control terminal and an attitude measurement terminal arranged at each action position of the excavator. The attitude measurement terminal includes a housing, a sensor arranged in the housing, a power supply battery and a wireless communication module, and the wireless communication module is used to transmit the data detected by the sensor to the main control terminal.

[0025] In this embodiment, by setting the attitude measurement terminal at each action position of the excavator, the action data of each part of the excavator can be collected, and the main control terminal can receive the action data of each part and perform data processing to obtain the overall action state of the excavator , so that the state monitoring of excavator movement can be realized. The attitude measurement terminal is set in the casing to...

Embodiment 2

[0039] This embodiment provides an excavator. The excavator operation state monitoring device described in Embodiment 1 is set on the excavator. The posture measurement terminals of the operation state monitoring device are respectively arranged on the chassis 8, the body 1, and the boom 2. , stick 3 or rocker 7, the main control terminal communicates with the main control module of the excavator, and the main control module obtains the action state data of the excavator sent by the main control terminal, and combines the action state data with the control of the excavator The data is compared, and when they are inconsistent, it is determined that there is a malfunction, an alarm command is issued, and the engine of the excavator is controlled to be shut down.

[0040] Specifically, such as figure 1 As shown, four attitude measurement terminals are set in this embodiment, including boom attitude measurement terminal 51 , arm attitude measurement terminal 52 , bucket attitude m...

Embodiment 3

[0045] This embodiment provides an excavator control method, such as figure 2 As shown, the method can be implemented in the main control module of the excavator, and is used to improve the safety of the excavator action, and can include the following steps:

[0046] Step 1. Obtain the attitude measurement data of each action position of the excavator and the control data of the excavator;

[0047] The attitude measurement data includes the data collected by the attitude measurement terminal arranged on the chassis 8, the body 1, the boom 2, the arm 3, the rocker 7 and the bucket 4, and may include the rotation angle of the chassis 8 and the body 1, the boom, 2 stick 3 and rocker 7 tilt angle data. The control data of the excavator may be the output signal of the operating handle.

[0048] Step 2, according to the positional relationship of each action position of the excavator and the acquired attitude measurement data of each position, generate the overall action data of ...

Abstract

The invention provides an excavator action state monitoring device, an excavator and a control method. The excavator action state monitoring device comprises a main control terminal and attitude measurement terminals arranged at all action positions of the excavator, each attitude measurement terminal comprises a shell, a sensor arranged in the shell, a power supply battery and a wireless communication module, and the wireless communication module is used for transmitting data detected by the sensor to the main control terminal. The excavator action state monitoring device is flexible in arrangement, can be installed on the excavator put into use to achieve performance improvement of an existing excavator, and can recognize misoperation at the initial stage of misoperation by comparing thedetected state with an excavator handle action signal, so that a shutdown instruction is sent to an engine, a shutdown instruction is sent to an engine, and the working safety of the excavator is improved.

Description

technical field [0001] The present disclosure relates to the technical field related to excavators, and in particular, relates to an excavator operation state monitoring device, an excavator and a control method. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art. [0003] In order to meet the needs of the market for intelligence and informatization, the excavator control system has begun to develop in the direction of full electric control, that is to say, the movements of the excavator are all electronically controlled. Even if the driver does not operate the excavator, the excavator can still move under the control of the control system. This presents the problem of safety, and puts forward higher requirements for the reliability of the components of the excavator control system. For example, failure of a certain component or a loophole in the c...
