Technical Field

The invention belongs to the field of grain condition monitoring, and particularly relates to a real-time grain condition monitoring system and method for bulk grain container transportation.

Background

The grain types, the yield, the supply and the demand of the grain in the south and the north of China are unbalanced, and the distribution of production and marketing places is uneven, so that the trans-regional grain transportation becomes a normal state. The container transportation is an important component of transregional food transportation in China due to the characteristics of convenience, high efficiency and flexibility. The grain container transportation is a storage and transportation coexisting process, and is influenced by the change of outside climate, and the grains in the container are likely to have the phenomena of dewing, mildewing, heating and the like in the long-time transportation process, so that the quality of the grains is influenced, and the quality of the grains is reduced and the economic loss is caused. If the temperature, humidity and CO of the grain can be mastered in the transportation process of the container₂The grain condition information such as change, take necessary grain and guarantee the quality transportation measure, will reduce the grain effectively and damage the risk.

At present, a grain temperature detection system is generally applied to grain storage, a multi-parameter grain condition monitoring system is also applied to popularization and application, but the grain condition monitoring tools are rarely applied to grain container transportation. Patent No. CN209131717U, "a wireless temperature and humidity detector for detecting grain conditions in grain container transportation" discloses a wireless temperature and humidity detector for detecting grain conditions in grain container transportation; patent No. CN105446279A, "a bulk grain container monitoring control system and method" discloses a bulk grain container monitoring control system capable of monitoring environmental climate information, bulk grain container position information, internal grain humiture, moisture and weight information in real time. The two patents solve the problems of grain situation data acquisition, monitoring and the like in grain container transportation to a certain extent, the first patent describes the structure of a detection system and the principle of a sensor, but does not describe a specific implementation method, for example, how the sensor is arranged in a container, and only comprehensively describes that the sensor can be arranged in the container. The second patent mainly describes an on-line weighing device which can prevent the grain inside the container from being stolen and a method for ventilating when the grain condition changes, but does not describe the mode of the ventilator configuration and power, and only describes that the grain condition detector (sensor) is directly put into the grain pile of the container, but does not describe how to install. In fact, as the position of the detector (sensor) changes along with the movement of the grain layer along with the change of the road surface in the transportation process, the damage risk of the detector (sensor) is increased, the transmitted data can be distorted or lost, and the digital monitoring management of the grain transportation process is impossible.
