[0019] As Figure 1 shown, the utility model provides a meteorological comprehensive dynamic detection system suitable for refrigerated freight railway platform, relative to the limitation of the observation data of the limited several meteorological observation stations of the fixed position railway line in the prior art, solve the prior art cannot carry out the problem of cross-regional, all-weather, high-precision, multi-element high-altitude meteorological comprehensive dynamic detection, the meteorological comprehensive dynamic detection system of the utility model adopts the special open container of railway to carry out the modification, the system includes equipment installation platform module, detection equipment module, monitoring equipment module, control communication module, distribution box module, installs microwave radiometer, cloud radar and other various meteorological equipment on the equipment lifting platform in the container, adopts the special open container of refrigerated freight train to modify, so as to cope with the technical problems such as equipment power supply, positioning damping, slope measurement, operation monitoring and meteorological data collection.

[0020] The equipment installation platform module is arranged in the container, and is used for fixedly installing meteorological equipment;

[0021] The detection equipment module is used for detecting and collecting various meteorological elements along the railway line and vehicle driving and attitude information;

[0022] The monitoring equipment module is used for remotely monitoring the equipment running state in real time;

[0023] The control communication module is used for controlling the opening and closing of the equipment installation platform module, the detection equipment module and the monitoring equipment module, and transmitting the meteorological data collected by the detection equipment module to the monitoring equipment module.

[0024] The distribution box module is used for directly taking power from the refrigerated freight train, and supplying power to the equipment installation platform module, the detection equipment module, the monitoring equipment module and the industrial computer module.

[0025] As Figure 1 shown, the layout and function of each module are as follows:

[0026] (1) distribution box module

[0027] The power distribution box draws power from the electrical box at the bottom of the refrigerated freight train container mounting platform, and then transmits power to the microwave radiometer, industrial control computer, switch, and communication gateway via circuit breakers. The microwave radiometer is powered by a separate circuit breaker, while the industrial control computer, switch, and communication gateway are powered by a separate circuit breaker. This isolates the power supply to the data acquisition equipment (microwave radiometer) and the control and communication equipment (industrial control computer, switch, and communication gateway) to prevent mutual interference in the event of equipment failure.

[0028] The distribution box, serving as a power distribution and signal aggregation hub, integrates circuit breakers, industrial control computers, switches, and communication gateways, and can be fixed to the side wall of an open container. It uses an air switch as the circuit breaker, automatically disconnecting when the current exceeds the rated current. Combining control and multiple protection functions, it not only contacts and disconnects circuits but also protects against short circuits, severe overloads, and undervoltage in circuits or electrical equipment.

[0029] (2) Testing equipment module

[0030] A. Microwave radiometer

[0031] The microwave radiometer is mounted on a lifting platform inside the train car via a shock absorber with vertical and lateral three-dimensional vibration isolation capabilities. The shock absorber is designed based on the quasi-zero stiffness principle to isolate low-frequency vibrations under light loads. The microwave radiometer selects multiple water vapor and oxygen radiation channels for parallel measurement of radiation brightness temperature. Combined with a dynamically adapted temperature and humidity profile inversion mode algorithm, it can dynamically acquire the upper-air temperature and humidity profiles along the railway line as the train is running.

[0032] B. Combined Inertial Navigation System

[0033] The microwave radiometer mounting platform is equipped with an IMU560 integrated inertial navigation system. The IMU560 series inertial measurement units (IMUs) are calibrated across the entire temperature range to meet performance requirements in different environments. A multi-data Kalman filter fusion algorithm is implemented through the built-in navigation computer, outputting real-time and accurate carrier attitude, heading, three-dimensional position, and velocity information. This provides relevant information for microwave radiometer beam pointing correction and dynamic adaptation of inversion mode algorithms.

[0034] (3) Monitoring equipment module

[0035] The monitoring camera and the sound-light alarm device are included, wherein the monitoring camera is installed on the top of the front wall in the carriage to realize remote real-time monitoring of the running state of the device. The monitoring camera adopts a PoE (Power over Ethernet) camera with integrated power supply and network design. The camera is supplied with power through a network cable, and does not need a separate power supply facility. It can be directly connected to a switch through a network cable, which simplifies the wiring and reduces the volume and maintenance cost. The PoE camera can automatically identify the device power and power requirements to ensure stable operation. The sound-light alarm device is used as a local alarm device to timely inform the personnel on the train.

[0036] (4) Control communication module

[0037] The control communication module mainly includes an industrial computer, a switch and a communication gateway.

[0038] The microwave radiometer is connected to the switch in the distribution box through a network cable. The detected meteorological data products are uploaded to the industrial computer through the switch, and data storage and backup are completed in the industrial computer. The IMU560 integrated inertial navigation system is connected to the RS422 interface of the industrial computer through a J30J-9pin connection line. The measured carrier attitude, heading information, three-dimensional position and speed information are uploaded to the industrial computer. The monitoring camera is connected to the PoE port of the switch through a network cable, and the remote real-time monitoring of the running state of the device is realized through the communication gateway.

[0039] The industrial computer can reliably operate in harsh environmental conditions in the open container. It has protection levels such as dust, smoke, high / low temperature, humidity, vibration and corrosion. The industrial computer serves as the signal processing hub, receiving information streams from the microwave radiometer, integrated inertial navigation system and monitoring camera and further processing them.

[0040] The switch uses an industrial-grade wide-temperature switch that can withstand harsh working environments and has strong anti-electromagnetic interference ability for complex electromagnetic environments in the train. The switch serves as an information interaction node to enable efficient and reliable information interaction between the microwave radiometer, integrated inertial navigation system, monitoring camera and industrial computer.

[0041] The communication gateway is used for data transmission. As an optimal solution, to ensure the safety of train information transmission, the train-to-station transmission method is used for data collection and processing, i.e., when the train arrives at the station, the industrial computer transmits the detected data to the station receiving station through the switch and the communication gateway, ensuring the safety of train information transmission.

[0042] (5) Special installation platform module

[0043] The inventor has found through experiments that the measured vibration frequency data of the roof accelerometer in the previous analysis shows that when the vehicle is normally driven, the vibration frequency of the train is mainly concentrated in the lateral and longitudinal impact of 30Hz-40Hz, and the lateral and longitudinal impact vibration at the frequency has a greater impact on the measurement accuracy of the microwave radiometer, and therefore the special installation damping platform is designed for the situation.

[0044] The special installation damping platform is designed by using the quasi-zero stiffness principle, and the low-frequency vibration of the lighter load is isolated, a special damper suitable for the comprehensive inspection train platform and the TK001S type small microwave radiometer is designed and developed, and has three-way vibration isolation capability in the vertical and lateral directions.

[0045] The above-mentioned embodiments only exemplarily illustrate the principles and effects of the present application, and are not used to limit the present application. Any person skilled in the art can modify or change the above-mentioned embodiments without departing from the spirit and scope of the present application.
