Description

Technical Field

[0001] This application relates to the field of transportation monitoring technology, and in particular to an alarm method, device and system. Background Technology

[0002] With societal development, businesses have placed greater emphasis on transportation safety. Lead seals are used to secure measuring equipment, preventing unauthorized opening and adjustment of its precision. The use of lead seals effectively reduces instances of arbitrary loading and unloading, cargo swapping, and theft during transport. Currently, the liquefied gas transportation industry primarily uses electronic lead seals. While electronic lead seals enhance vehicle safety, they still cannot fully meet the demands of rapidly growing businesses.

[0003] Currently, the existing electronic seals in the liquefied gas transportation industry include a seal shell, tag antenna, tag chip, metal support, one-way spiking, cable insertion hole, metal reinforcement block, and flexible steel cable. The shell is formed by injection molding, encapsulating the tag antenna, tag chip, metal support, one-way spiking, and metal reinforcement block. The cable insertion hole is a through-hole that penetrates the seal shell and the metal reinforcement block. Such RFID electronic seals have the following functions: they possess electronic anti-tampering capabilities, enabling real-time monitoring of the seal's status, and also solving the problems of seal forgery, poor confidentiality, and poor data recording capabilities.

[0004] In the power industry, intelligent lead seals with active alarm capabilities are currently used. These mainly consist of a wireless communication module, a line break monitoring module, a perpetual calendar clock module, a controller, a data storage device, and an authentication module. Their main functions are: the wireless communication module, a wireless communication interface circuit, reads data and opening information from the intelligent lead seal and connects to the controller; the line break monitoring module records and uploads the event of the opened seal and connects to the controller; the perpetual calendar clock module provides a time stamp for the event record as a verification basis and connects to the controller; the controller primarily controls the wireless communication module, line break monitoring module, and perpetual calendar clock module, reading data from them and storing it in the data storage module. Furthermore, the controller can exchange data with a remote monitoring computer through the authentication module, which is connected to both the data storage device and the authentication module; the data storage device stores various information collected by the controller; and the authentication module connects to the remote monitoring computer via the wireless communication module, enabling real-time online monitoring.

[0005] Currently, smart seals in the power industry are more intelligent and collect more comprehensive information than the electronic seals used in the liquefied petroleum transport industry. However, current smart seals in the power industry lack explosion-proof properties, making them unsuitable for LNG transportation, and they also lack the ability to function properly in harsh, ultra-low temperature environments.

[0020] In some embodiments, the state parameters further include light intensity, and the step of obtaining the pressure values ​​when the doors of the carriage are opened and closed includes:

[0021] Compare the light intensity with the preset light threshold;

If the theft or replacement of LNG is confirmed, a warning message is issued to achieve intelligent monitoring of the LNG transport vehicle's transportation status.

[0036] Based on the temperature change difference in the vehicle compartment status parameters, it is determined whether there is any liquid theft or liquid replacement. Then, based on the difference between the pressure value when the door is closed and the pressure value when the door is open in the vehicle compartment status parameters, it is determined whether there is any liquid theft or liquid replacement, thus achieving a precise determination of the LNG transport vehicle's transport status.

The described embodiments should not be regarded as limitations on this application.

It is understood that "first, second, third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.

The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0046] Based on the problems existing in related technologies, this application provides an alarm method for the transportation status of transport vehicles. Figure 1 This is a schematic flowchart of a transportation vehicle transportation status alarm method provided in an embodiment of this application, as shown below. Figure 1 As shown, it includes:

[0047] Step S101: Obtain the compartment status parameters of the transport vehicles en route.

[0048] In some embodiments, the transport vehicle en route is determined through the following steps:

[0049] Obtain the satellite positioning information of the transport vehicle;

[0050] The computing vehicle is monitored in real time based on the satellite positioning information.

[0051] In the above embodiments, the satellite positioning information of the transport vehicle can be obtained by installing a Beidou positioning device on the transport vehicle, thereby monitoring the location of the transport vehicle in real time. The transport vehicle travels along a predetermined route, which includes the transport route known to the monitoring personnel before departure or during transport. The monitoring personnel can compare the real-time satellite positioning information with the information of the predetermined route to determine whether the transport vehicle is en route.

[0052] Step S102: Based on the status parameters, determine whether there is any theft or replacement of liquid.

[0053] In some embodiments, the carriage status parameters include temperature information, and determining whether there is any fluid theft or fluid replacement based on the status parameters includes:

[0054] If the temperature change difference exceeds the preset temperature change value and the duration exceeds the preset time, it is determined that there is a case of liquid theft or liquid replacement.

[0055] In the above embodiments, when the method provided in this application is applied to materials that require specific transportation temperatures, such as liquefied gas, when there are operations such as loading, unloading, stealing, or changing materials on the transport vehicle, the temperature inside the transport vehicle will change. In some embodiments, the temperature change difference is detected at the outer wall of the loading and unloading port of the transport vehicle.

[0056] In some embodiments, the principle of a thermistor is utilized. When a platinum resistance thermometer is connected to a circuit, the circuit will generate a corresponding current change according to the temperature change. The tester of the platinum resistance thermometer can plot the corresponding temperature-resistance graph based on the change. When applied to the circuit implementing the method of this application, the temperature value to be measured can be estimated according to a certain calculation formula.

[0057] In the above embodiment, the formula for calculating the change in resistance of the platinum resistance thermometer with temperature is: Rt = Rt0[1 + α(t - t0)], where Rt is the resistance value at temperature t, Rt0 is the resistance value at temperature t0 (usually t0 = 0℃), and α is the temperature coefficient. The temperature and resistance of the platinum resistance thermometer have an approximately linear relationship. A preset temperature change value of 5℃ and a preset time of 300s are set.

[0058] In some embodiments, the status parameter further includes a pressure value, and determining whether there is fluid theft or fluid replacement based on the status parameter includes:

[0059] Obtain the pressure values ​​when the doors of the carriage are opened and closed;

[0060] Calculate the difference between the pressure value when the door is closed and the pressure value when the door is open;

[0061] Compare the difference with a preset difference range;

[0062] If the difference exceeds a preset difference range, it is determined that liquid theft has occurred.

[0063] When the difference meets the preset difference range, it is determined that a fluid replacement has occurred.

[0064] In the above embodiments, in addition to the preset difference range, the determination of whether there is liquid theft or liquid replacement can also be made by combining the actual duration of the temperature change difference.

[0065] In some embodiments of the above embodiments, the pressure value is measured by a pressure gauge inside the vehicle compartment. The pressure gauge is a fixed accessory of the transport vehicle. A reading instrument is matched with it, which enables the terminal using the method of this application to directly obtain the pressure value. Using the pressure gauge of the vehicle's fixed accessory does not affect the overall stable structure of the transport vehicle.

[0066] In some embodiments, instead of specifically determining whether there is liquid theft or liquid replacement, a classification is made. For example, a difference of 0-2V is considered normal wear and tear and is within the normal range due to vehicle movement. A difference of 2-5V indicates minor liquid replacement, and a difference of 5V or more indicates serious liquid replacement.

[0067] In some embodiments, the state parameters further include light intensity, and the step of obtaining the pressure values ​​when the doors of the carriage are opened and closed includes:

[0068] Compare the light intensity with the preset light threshold;

[0069] When the light intensity is greater than the preset light threshold, it is determined that the door of the carriage is open, and the pressure value when the door of the carriage is opened is obtained;

[0070] When the light intensity is less than a preset light threshold, it is determined that the door of the carriage is closed, and the pressure value when the door of the carriage is closed is obtained.

[0071] In the above embodiments, the light intensity can be obtained by a light sensor. The working principle of the light sensor is based on the hotspot effect principle, and most importantly, it uses a detection component that is highly responsive to weak light. Within the linear range, the output signal of the light sensor is proportional to the light intensity. Visible light passing through the filter illuminates the inlet photodiode, and the photodiode converts the visible light intensity into an electrical signal.

[0072] In the above embodiments, the alarm method further includes:

[0073] When liquid theft is detected, the amount of liquid stolen is determined based on the difference in pressure values.

[0074] Step S103: If it is determined that there is liquid theft or liquid replacement, a warning message is issued.

[0075] This application provides an electronic device; Figure 2 This is a schematic diagram of the composition structure of the electronic device provided in the embodiments of this application, such as... Figure 2 As shown, the electronic device includes: a processor 210, at least one communication bus 250, a user interface 240, at least one external communication interface 230, and a memory 220.
