Embodiment 1

[0042] figure 2 It is a flow chart of a trailer state detection method provided by Embodiment 1 of the present invention. The trailer state detection method provided in this embodiment is completed by the host integrated on the trailer. see figure 2 , the trailer state detection method includes:

[0043] S101. Detect vibration parameters of the trailer within a preset time period.

[0044] Optionally, the vibration parameters of the trailer include the acceleration of the trailer in the three-dimensional direction (such as the acceleration in the X direction, the acceleration in the Y direction, and the acceleration in the Z direction, wherein any two of the X direction, the Y direction, and the Z direction are perpendicular to each other) and Acceleration acquisition frequency. It should be noted that if the collection frequency of the acceleration is different, the acceleration in the X direction, the acceleration in the Y direction, and the acceleration in the Z direc...

Embodiment 2

[0072] Figure 4 It is a flow chart of a trailer state detection method provided by Embodiment 2 of the present invention. This embodiment is a specific example of the first embodiment. see Figure 4 , the trailer state detection method includes:

[0073] First, install a host (eg, the model of the host is MT2503D) with a vibration sensor (eg, the model of the vibration sensor is LIS2DH12) on the trailer, turn on the vibration detection mode, and send the vibration data (including the trailer in the The acceleration in the X direction, the acceleration in the Y direction, the acceleration in the Z direction, and the acquisition frequency of the acceleration) are stored in the SD card of the host.

[0074] Secondly, a period of data collection is carried out. In the actual business operation process, the customer or driver can click on the APP to record the start loading time, loading completion time, unloading start time, unloading completion time, departure time, Time of ...

Embodiment 3

[0079] Figure 6 It is a structural block diagram of a trailer state detection device provided in Embodiment 3 of the present invention. see Figure 6 , the trailer state detection device includes a trailer vibration parameter detection module 310 , a trailer vibration parameter input module 320 , a trailer state determination module 330 and a trailer state sending module 340 .

[0080] Wherein, the trailer vibration parameter detection module 310 is used to detect the trailer vibration parameters within a preset time period;

[0081] The trailer vibration parameter input module 320 is used to input the trailer vibration parameters within the preset time period into the trailer state model, the trailer state model includes functions related to the trailer vibration parameters and the trailer state, and the trailer The state includes at least one of a stay state, a loading state, an unloading state and a driving state;

[0082] The trailer state determination module 330 is u...

Abstract

The embodiment of the invention discloses a trailer state detection method and a trailer state detection device. The trailer state detection method comprises the steps that trailer vibration parameters in a preset time period are detected; the trailer vibration parameters within the preset time period are input into a trailer state model, wherein the trailer state model comprises a function aboutthe trailer vibration parameters and the trailer state, and the trailer state comprises at least one of a staying state, a loading state, an unloading state and a driving state; the trailer state model determines the trailer state based on the trailer vibration parameters; and when the trailer state of the trailer changes, the trailer state is sent out, so that the interaction frequency of the sensor and the monitoring terminal is reduced, and the communication and maintenance cost is saved.

Description

technical field [0001] Embodiments of the present invention relate to automobile transportation technology, and in particular to a trailer state detection method and a trailer state detection device. Background technique [0002] Drop-and-pull transportation refers to an organizational method in which vehicles are dropped or attached to designated trailers at each loading and unloading operation point according to a predetermined plan, and continue to run. Drop-and-hook transport can minimize the downtime of trucks (or tractors), thereby maximizing the use of traction capacity and improving transport efficiency. [0003] In drop and pull transportation, the tractor can be separated from the trailer, and the trailer is the main body of the cargo, and its position and status are what we care about. At present, various sensors are usually installed in the trailer, and each sensor reports the collected data to the monitoring terminal, and the monitoring terminal determines the ...
