[0002] At present, the field operation reliability test of grain combine harvesters mostly adopts the method of test personnel tracking the vehicle, manual recording, and manual data aggregation and processing. It is not only time-consuming and labor-intensive, but the test is easily restricted by personal subjective factors, making it difficult for the large amount of test data collected to play a role in product improvement.

[0003] With the advancement and practical application of technologies such as satellite positioning, wireless transmission, and sensors, remote monitoring of reliability tests for grain combine harvesters can also be achieved through information and intelligent means, which can improve the efficiency of reliability tests, the accuracy of test results, reduce the labor intensity of manual labor, and reduce test costs. At present, the reliability test remote monitoring system is generally used for tractor reliability tests. Tractor reliability tests have high machine integration and easy collection of operating parameters, but lack monitoring and fault judgment of key working parts of grain combine harvesters (such as headers, rollers, elevators, etc.), so it is not suitable for field operation reliability tests of grain combine harvesters.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application.

Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] Figure 1 Schematic diagram of the structure of the remote monitoring system for the reliability test of the field operation of the grain combine harvester provided in the embodiment of the present application. Figure 1 The remote monitoring system for field operation reliability test of a grain combine harvester provided in the embodiment of the present application may include:

[0027] Remote monitoring platform and one or more reliability test monitoring terminals;

[0028] The reliability test monitoring terminal is arranged on the grain combine harvester; the reliability test monitoring terminal includes a monitoring host; the monitoring host is arranged in the cab of the grain combine harvester; the monitoring host is used to obtain the operation data of the grain combine harvester and transmit the operation data to the remote monitoring platform; the operation data includes: positioning information, parameter information and operation video of the grain combine harvester;

[0029] The remote monitoring platform is used to monitor the operating conditions of the grain combine harvester based on the operating data.

[0030] Field operation reliability test is an effective way to evaluate the performance and quality of grain combine harvester products. Through reliability test, various faults that occur in the actual operation of the product can be found, and then the fault conditions can be analyzed and verified to find out the problems in the design and manufacturing of the product, which is conducive to further improving the product quality.

[0031] The present application proposes a remote monitoring system for reliability tests of field operations of grain combine harvesters, including a remote monitoring platform and one or more reliability test monitoring terminals. By installing the reliability test monitoring terminal on the grain combine harvester, the operation position, time, operating status of key working parts (such as headers, rollers, elevators), operation videos, engine ECU data, and operation quality parameters of the grain combine harvester can be monitored in real time. After receiving these data, the remote monitoring platform analyzes and processes the operating area, operating duration, and automatically monitored fault conditions of the grain combine harvester, so as to realize remote monitoring and real-time fault monitoring, and grasp the reliability test conditions of the grain combine harvester in the field.

[0032] Specifically, the normal operating range of key operating parameters such as engine speed, oil temperature, reel speed, material conveying speed of the intermediate conveyor device, drum speed, and elevator speed can be preset according to the basic parameters of different models. The remote monitoring platform can receive and store data sent by each reliability test monitoring terminal in real time. When the real-time monitoring data exceeds the normal operating range, the remote monitoring platform can give a fault reminder. The test personnel can view the fault reminder and key operating parameters through the remote monitoring platform, and can view the on-site operation status in real time through the camera, and communicate with the driver to confirm the fault problem.

[0033] The remote monitoring platform can record the working time of the reliability test monitoring terminal, and automatically distinguish the operating time, idle time, and fault time according to the situation. When the grain combine harvester is in operation and all key components are working normally, it is judged as normal operation, and the accumulated time at this time is the operating time; when the reliability test monitoring terminal is turned on, and the grain combine harvester speed is zero and all key working components are not working, it is judged as not operating, and the accumulated time at this time is the idle time; when the platform finds a fault, the remote monitoring platform can automatically record the start time, and until the fault is eliminated, automatically calculate the fault time.

[0034] The remote monitoring platform can automatically calculate the operating area and header height of the grain combine harvester based on the positioning trajectory, speed, and working conditions of each key component of the grain combine harvester. Through data processing methods, the test reliability results and operating efficiency can be automatically generated based on information such as operating time, operating area, and operating fuel consumption.
