Embodiment 1

[0048]Compared with infrared detection, ultrasonic detection has the advantages of strong directivity, long detection distance, low cost, and little weather disturbance; compared with infrared, Bluetooth and wireless LAN transmission, ZigBee has low power consumption, low cost, and anti-interference ability Therefore, based on ultrasonic detection and ZigBee wireless communication technology, a real-time monitoring system for cargo loading and reinforcement during transportation can be built to realize real-time monitoring of cargo deviation during the entire operation and ensure the safety of railway and road cargo transportation .

[0049] The energy consumption of ultrasonic waves is slow in the process of propagating in the medium, and the propagation distance is relatively long. Ultrasonic detectors are commonly used for ranging objects and often work well in bad weather. The detector transmits ultrasonic wave and receives the ultrasonic wave bounced back by the cargo, c...

Embodiment 2

[0161] The ultrasonic monitoring unit collects distance information between the ultrasonic monitoring unit and the goods carried by the vehicle in various scenarios, and transmits the distance information to the receiving terminal through the wireless transmission unit. The various scenarios include In the road scene test, the car body is in a static state, the car body is driving on a flat road section, the car body is driving on a bumpy road section, and the cargo is offset.

[0162] The receiving terminal can also use Chebyshev's inequality to determine and eliminate abnormal values ​​of distance information in various scenarios, and to perform normal distribution test, independent sample variance test and sum of distance information in various scenarios. t test and / or use Chebyshev's inequality to judge outliers.

[0164] In order to test the working condition of the monitoring and alarm device under the influence of road curves, bumpy road sec...

Embodiment 3

[0193] In order to test the applicability of the system on actual railway vehicles and to simulate the actual application of the system in railway freight transport, an impact test was carried out at CRRC Erqi Vehicle Factory in Fengtai District to simulate the connecting process of vehicles; The comparison of the data collected by the monitoring system determines the accuracy of the monitoring data.

[0194] Nail the ultrasonic ranging module on the wooden floor of the vehicle, and test the changes of monitoring data during the static and dynamic processes of the container and cargo respectively, so as to verify the feasibility of the system in practical application. a test point is installed in the longitudinal direction of the container, b test point is installed in the longitudinal direction of the cargo, and is used to record the initial placement position of the cargo.

[0195] Because the vehicle will form a large impact force when it is connected, even if it is connect...

Abstract

The invention provides a system for monitoring loading and strengthening status of goods in transit in real time. The system comprises an ultrasonic monitoring unit, a wireless transmission unit and areceiving terminal, wherein the ultrasonic monitoring unit is connected with the wireless transmission unit by means of a circuit; the wireless transmission unit is connected with the receiving terminal by means of a wireless network. The ultrasonic monitoring unit detects the distance information between the monitoring unit and goods carried by a vehicle by transmitting ultrasonic waves, and transmits the distance information to the wireless transmission unit; the wireless transmission unit transmits the distance information to the receiving terminal by means of the wireless network; the receiving terminal is arranged in a cab; the distance information is displayed in real time by means of a display screen of the terminal, and the offset state of the goods is determined according to a preset alarm distance threshold. The device provided by the invention can be used for performing real-time monitoring and alarm on the displacement of the goods in freight transportation on a road and arailway, and can help a driver to find the movement, eccentric load and eccentric weight of the goods in time, thus reducing the occurrence of related accidents, and guaranteeing the safe transportation of the goods.

Description

technical field [0001] The invention relates to the technical field of cargo transportation safety monitoring, in particular to a real-time monitoring system for cargo loading and reinforcement status during transportation. Background technique [0002] Oversized cargo is the general term for oversized cargo, super long cargo and bulky cargo. Due to the special shape of the goods, affected by external factors such as weather, geographical environment, and line conditions on the way, large and large goods are prone to deviation and movement during transportation, which may cause driving accidents such as vehicle unbalanced load, derailment, and overturning. While carrying goods, it may also cause serious damage to the equipment along the railway, affect the normal operation of the railway, and even cause serious off-road casualties. Therefore, real-time monitoring and alarming of the deviation of bulky cargo transportation can detect and eliminate potential safety hazards in...
