Detailed Description
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, embodiments accompanying the drawings are described in detail below.
The inventor finds in the research of the traditional hydrogen cylinder monitoring method that the traditional hydrogen cylinder monitoring mainly monitors the temperature and the stress in the hydrogen cylinder, and cannot monitor the overall temperature distribution and the stress distribution of the hydrogen cylinder body. When the surface temperature or stress of the hydrogen cylinder changes greatly, the driving safety is affected because the real-time monitoring cannot be carried out.
Based on this, this application embodiment provides a hydrogen cylinder monitoring system, and this monitoring system includes temperature detecting system and stress detecting system. The temperature detection system can comprise a plurality of temperature detection devices, and different temperature detection devices are distributed and deployed at different positions on the surface of the hydrogen cylinder, so that the overall temperature distribution of the hydrogen cylinder can be detected; the stress detection system can comprise a plurality of stress detection devices, and different stress detection systems are distributed and arranged at different positions on the surface of the hydrogen cylinder, so that the overall stress distribution of the hydrogen cylinder can be detected. Therefore, through the monitoring system provided by the embodiment of the application, the whole temperature distribution and the stress distribution of the hydrogen cylinder can be monitored in real time, and when the temperature of the cylinder body is too high or the stress changes greatly, the safety of vehicle operation can be improved by automatic alarm.
Here, the stress refers to an internal force that generates an interaction between each part in the object when the object is deformed by an external factor (stress, humidity, change in temperature field, or the like), and attempts to restore the object from a position after the deformation to a position before the deformation against the action of the external factor.
To facilitate understanding of the monitoring system provided in the embodiments of the present application, the monitoring system will be described below with reference to the accompanying drawings.
Referring to fig. 1, which is a block diagram of a hydrogen cylinder monitoring system according to an embodiment of the present disclosure, as shown in fig. 1, the system may include: a temperature sensing system 100 and a stress sensing system 200.
The temperature detection system 100 at least comprises two temperature detection devices 101, and different temperature detection devices are arranged at different positions on the surface of the hydrogen cylinder. The temperature detection device 101 is configured to detect a temperature of a location, and as shown in fig. 1, the temperature detection device may be distributed on the surface of the hydrogen cylinder to collect temperature information of different locations of the hydrogen cylinder.
The stress detection system 200 includes at least two stress detection devices 201, different ones of which are deployed at different locations on the surface of the hydrogen cylinder. The stress detection device 102 is configured to detect stress at a location, as shown in fig. 1, the temperature detection device may be distributed on the surface of the hydrogen cylinder to collect stress information at different locations of the hydrogen cylinder.
In a specific implementation, the temperature detection device may be a thermocouple or a temperature sensor; the stress detection device may be a strain gauge or a stress sensor.
In one possible implementation, the monitoring system may further include a data acquisition device 300 and a data receiving device 400, as shown in fig. 2. The data acquisition device 300 is used for acquiring the temperature information of the hydrogen cylinder from each temperature detection device and acquiring the stress information of the hydrogen cylinder from each stress detection device; and simultaneously sending the acquired temperature information and stress information to data receiving equipment.
And the data receiving device 400 is used for analyzing and processing the temperature information and the stress information to obtain the temperature distribution and the stress distribution of the hydrogen cylinders. The data receiving device can be a vehicle-mounted computer, a portable computer, a mobile phone and other user terminals.
In specific implementation, the data acquisition device acquires the detected temperature information of the position of the data acquisition device from each temperature detection device through the data line, acquires the detected stress information of the position of the data acquisition device from each stress detection device, and sends the acquired temperature information and the stress information to the data receiving device. And after receiving the temperature information and the stress information, the data receiving equipment respectively analyzes and processes the temperature information and the stress information to obtain the temperature distribution condition and the stress distribution condition of the hydrogen cylinder.
In practical application, the data receiving device can compare and analyze the received temperatures of different positions to obtain a chart and/or a cloud chart of temperature distribution, so that the overall temperature distribution of the hydrogen cylinder and the temperature difference of different positions can be intuitively known. Similarly, the data receiving device can compare and analyze the received stresses at different positions to obtain a stress distribution chart and/or a cloud chart, so that the stress distribution of the whole hydrogen cylinder and the stress difference at different positions can be intuitively known.
It can be understood that the temperature information and the stress information obtained by the temperature detection device or the stress detection device are not visual temperature data and stress data, so that the data receiving device can directly process the temperature information and the stress information sent by the data acquisition device, and the data acquisition device can convert the temperature information and the stress information before sending the temperature information and the stress information to the data receiving device to obtain visual temperature data and stress data, so that the data receiving device can analyze and process the temperature data and the stress data to obtain the temperature distribution and the stress distribution of the hydrogen cylinder. Specifically, the data acquisition device is further configured to perform conversion processing on the temperature information and the stress information to obtain temperature data and stress data, and send the temperature data and the stress data to the data receiving device; and the data receiving equipment is specifically used for analyzing and processing the temperature data and the stress data to obtain the temperature distribution and the stress distribution of the hydrogen cylinder.
It should be noted that the data acquisition device may also directly send the acquired temperature information and stress information to the data receiving device, and the data receiving device converts the temperature information and the stress information to obtain the temperature data and the stress data.
In practical application, when the data acquisition device is close to the data receiving device, the acquired temperature information and stress information can be sent to the data receiving device from the data acquisition device through a wire through wired connection. When the data acquisition device is far away from the data receiving device, in order to avoid the wiring between the data acquisition device and the data receiving device and facilitate information transmission, the monitoring system may further include a wireless transmitter 500, as shown in fig. 2. The wireless transmitter 500 is located between the data acquisition device and the data receiving device, and is configured to send the temperature information and the stress information acquired by the data acquisition device to the data receiving device. Namely, the data acquisition equipment sends the acquired temperature information and stress information to the data receiving equipment through the wireless transmitter, so that wiring from the roof data acquisition equipment to the data receiving equipment is avoided, and the temperature information and the stress information can be acquired in real time even if the vehicle is in an operating state, and the data transmission efficiency is improved.
It will be appreciated that the hydrogen cylinders, which are the primary energy source for the vehicle, may be located under the vehicle or on the vehicle roof. When the hydrogen cylinders are located on the vehicle roof, a data acquisition device and a wireless transmitter are correspondingly arranged on the vehicle roof, wherein the data acquisition device and the wireless transmitter can be connected through wires, and a data receiving device is located in the vehicle, as shown in fig. 3. In fig. 3, 1 denotes a temperature detection device, 2 denotes a stress detection device, 3 denotes a data acquisition device, 4 denotes a wireless transmitter, and 5 denotes a data reception device.
It can be understood that when the hydrogen cylinder is positioned at the bottom of the vehicle, the data acquisition equipment and the data receiving equipment can be directly connected by a wire, and data transmission is carried out by the wire.
As can be seen from the above description, the monitoring system includes a temperature detection system and a stress detection system. The temperature detection system can comprise a plurality of temperature detection devices, and different temperature detection devices are distributed and deployed at different positions on the surface of the hydrogen cylinder, so that the overall temperature distribution of the hydrogen cylinder can be detected; the stress detection system can comprise a plurality of stress detection devices, and different stress detection systems are distributed and arranged at different positions on the surface of the hydrogen cylinder, so that the overall stress distribution of the hydrogen cylinder can be detected. Therefore, through the monitoring system provided by the embodiment of the application, the whole temperature distribution and the stress distribution of the hydrogen cylinder can be monitored in real time, and when the temperature of the cylinder body is too high or the stress changes greatly, the safety of vehicle operation can be improved by automatic alarm.
