Description

Technical Field

[0001] This invention relates to the field of parking control technology for hazardous materials transport vehicles, and particularly to a parking method, apparatus, equipment, and readable storage medium for hazardous materials transport vehicles. Background Technology

[0002] Due to the special nature of the hazardous materials transportation industry, high safety requirements are placed on hazardous materials transport vehicles. This includes vehicles transporting petroleum oil tankers, liquefied gas tankers, flammable and explosive chemicals, and military ammunition, as well as the warehouse environments in which these vehicles are located, such as armories or dusty workshops. In these environments, hazardous materials transport vehicles are highly susceptible to explosion if an electric arc is generated. Furthermore, in extreme emergencies, such as an unavoidable collision during transit, leakage of the transported hazardous materials, or dust dispersion, the resulting electric arc can also cause an explosion or fire. Therefore, after a hazardous materials transport vehicle has stopped normally or abnormally (due to a collision), it is imperative to quickly and completely disconnect the power supply to the entire vehicle.

[0003] In order to quickly and completely cut off the power supply to the vehicle, some vehicles are equipped with an emergency power-off system. Its main function is to quickly cut off the power supply to the vehicle by disconnecting the emergency stop switch, thereby reducing safety hazards caused by the electrical system.

[0004] However, existing solutions typically require manual operation to disconnect the emergency stop switch, which can lead to situations where the driver forgets to do so. Furthermore, in the event of an abnormal stop, the driver may be injured and lose the ability to disconnect the emergency stop switch, posing a safety hazard. Summary of the Invention

[0046] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] This invention provides a method for parking a hazardous materials transport vehicle, which solves the technical problem that existing methods require drivers to manually disconnect the vehicle's power supply when parking hazardous materials transport vehicles, posing safety hazards when drivers forget to operate or are unable to perform the operation.

[0048] See Figure 1 As shown, this embodiment of the invention provides a method for parking a hazardous materials transport vehicle, including the following steps:

[0049] Step S10: Obtain the parking parameter values ​​of the vehicle; the parking parameter values ​​are the vehicle body acceleration value or the seat belt acceleration value.

[0050] Specifically, see Figure 2As shown, an acceleration sensor can be installed on the vehicle body, and the controller in the instrument panel can obtain the vehicle's parking acceleration value based on the parameters collected by the acceleration sensor. Alternatively, a force sensor can be installed on the seat belt, and the controller in the instrument panel can obtain the seat belt acceleration value based on the parameters collected by the force sensor. This embodiment of the invention also provides a parking device for a hazardous materials transport vehicle. The parking device is connected to the instrument panel via a CAN bus to obtain the parking vehicle acceleration value or the parking seat belt acceleration value. The CAN bus has advantages such as strong real-time performance, long transmission distance, strong anti-electromagnetic interference capability, and low cost. It adopts a two-wire serial communication method, has strong error detection capability, can work in high-noise interference environments, can automatically retransmit after the transmitted information is corrupted, and nodes have the function of automatically exiting the bus in case of serious errors.

[0051] Step S20: Determine whether the vehicle is parked normally based on the vehicle's parking parameter values.

[0052] Specifically, determining whether a vehicle is parked correctly based on its parking parameter values ​​includes:

[0053] Determine whether the parking parameter value is less than a preset parameter threshold;

[0054] If so, determine that the vehicle is parked normally;

[0055] If not, determine that the vehicle is parked abnormally.

[0056] Specifically, if the parking parameter value is the vehicle acceleration value, it checks whether the vehicle acceleration value is less than a preset vehicle acceleration threshold. This is for the case of deceleration while parking, and the absolute value of the vehicle acceleration value is considered. For example, if the vehicle acceleration value is less than 6 m / s²... 2 This indicates that the parking was relatively smooth and was a normal parking maneuver. If the vehicle's acceleration is not less than 6 m / s², then... 2 (typically 10m / s) 2 The above indicates that a collision may have occurred, and the vehicle is parked abnormally.

[0057] If the parking parameter value is the parking seatbelt acceleration, it checks whether the parking seatbelt acceleration is less than a preset seatbelt acceleration threshold. For example, if the parking seatbelt acceleration is less than 0.8g (g is the acceleration due to free fall), it indicates a relatively smooth stop, which is normal parking. If the parking seatbelt acceleration value is not less than 0.8g (usually above 2g), it indicates that a collision may occur, which is abnormal parking. It should also be noted that the preset parameter threshold can also be a range of values.

[0058] Step S30: If it is determined that the vehicle is parked normally, disconnect the vehicle power supply.

[0059] Specifically, disconnecting the vehicle's power supply includes:

[0060] Disconnect the excitation circuit of the excitation generator to stop the excitation generator from generating electricity;

[0061] Disconnect all vehicle electrical equipment from the battery.

[0062] See Figure 3 As shown, this invention uses an excitation generator as the generator. The normally open contact of relay S1 in the excitation circuit of the excitation generator is opened, and the normally closed contact is closed, causing the excitation generator to stop generating electricity. The vehicle's electrical equipment is also disconnected from the battery, specifically by disconnecting the switch S2 built into the parking device of the hazardous materials transport vehicle.

[0063] Figure 3 In the process, the relay S1 in the excitation circuit of the excitation generator G is controlled by the parking device of the hazardous materials transport vehicle. When generating electricity normally, the normally open contact of the control relay S1 is closed and the normally closed contact is opened, and the excitation generator G is normally excited and generates electricity to the vehicle's electrical equipment or battery. When it is not necessary to generate electricity, the normally open contact of the control relay S1 is opened and the normally closed contact is closed, and the excitation generator G is not excited. Even if the excitation generator G rotates, it will not generate electricity, and the entire vehicle loses power supply. Compared with traditional generators, the power outage is more thorough.

[0064] Step S40: If it is determined that the vehicle is abnormally stopped, disconnect the vehicle power, turn on the emergency call device, and send an emergency call signal to the emergency call recipient.

[0065] Specifically, activating the rescue call device and sending a rescue call signal to the rescue recipient through the rescue call device includes:

[0066] Turn on the microphone, speaker, and wireless communication module of the emergency call device;

[0067] The wireless communication module continuously sends rescue call signals to the rescue recipient at preset intervals.

[0068] See Figure 2 As shown, the emergency call device is equipped with a microphone, speaker, and wireless communication module (from right to left). When an abnormal vehicle stop is detected, the vehicle's power is disconnected, and the battery built into the hazardous materials transport vehicle's parking device is used as a backup power source. The microphone, speaker, and wireless communication module of the emergency call device are then activated. The hazardous materials transport vehicle's parking device can continuously send emergency call signals to the rescue recipient (which can be a rescue organization or rescue platform) at preset intervals via the wireless communication module. The microphone and speaker, once activated, can be used by the driver or passengers to contact the rescue organization.

[0069] The method for parking a hazardous materials transport vehicle in this embodiment of the invention first obtains the vehicle's parking parameter values, then determines whether the vehicle is parked normally based on these parameters, and finally disconnects the vehicle's power supply based on the determination, or, based on disconnecting the vehicle's power supply, activates the emergency call device and sends an emergency call signal to the emergency responder. This invention can automatically disconnect the vehicle's power supply when a hazardous materials transport vehicle is parked and can send an emergency call signal in case of abnormal parking, thus improving safety.

[0070] See Figure 4 As shown in the figure, this embodiment of the invention also provides a parking device for a dangerous goods transport vehicle, including: an acquisition unit, a judgment unit, a first execution unit, and a second execution unit.

[0071] The acquisition unit is used to acquire the parking parameter values ​​of the vehicle; the parking parameter values ​​are the vehicle body acceleration value or the seat belt acceleration value.

[0072] Specifically, see Figure 2 As shown, an acceleration sensor can be installed on the vehicle body, and the controller in the instrument panel can obtain the vehicle's parking acceleration value based on the parameters collected by the acceleration sensor. Alternatively, a force sensor can be installed on the seat belt, and the controller in the instrument panel can obtain the seat belt acceleration value based on the parameters collected by the force sensor. The parking device of the hazardous materials transport vehicle is connected to the instrument panel via a CAN bus to obtain the parking vehicle acceleration value or the parking seat belt acceleration value. The CAN bus has advantages such as strong real-time performance, long transmission distance, strong anti-electromagnetic interference capability, and low cost. It adopts a two-wire serial communication method, has strong error detection capability, can work in high noise interference environments, can automatically retransmit after the transmitted information is corrupted, and nodes have the function of automatically disconnecting from the bus in case of serious errors.

[0073] The judgment unit is used to determine whether the vehicle is parked normally based on the vehicle's parking parameter values.

[0074] Specifically, the judgment unit is used to determine whether the vehicle is parked normally based on the vehicle's parking parameter values, specifically including:

[0075] Determine whether the parking parameter value is less than a preset parameter threshold;

[0076] If so, determine that the vehicle is parked normally;

[0077] If not, determine that the vehicle is parked abnormally.

[0078] Specifically, if the parking parameter value is the vehicle's acceleration value, it checks whether the acceleration value is less than a preset acceleration threshold. This is for the case of deceleration while parking, so the absolute value of the acceleration value is considered. For example, if the acceleration value is less than 6 m / s²... 2This indicates a relatively smooth stop, which is a normal stopping condition. If the acceleration value is not less than 6 m / s², then... 2 (usually 10m / s) 2 The above indicates that a collision may have occurred, and the vehicle is parked abnormally.

[0079] If the parking parameter value is the parking seatbelt acceleration, it determines whether the parking seatbelt acceleration is less than a preset seatbelt acceleration threshold. For example, if the parking seatbelt acceleration is less than 0.8g, it indicates a relatively smooth stop, which is normal parking. If the parking seatbelt acceleration value is not less than 0.8g (usually above 2g), it indicates that a collision may occur, which is abnormal parking. It should also be noted that the preset parameter threshold can also be a range of values.

[0080] The first execution unit is used to disconnect the vehicle power supply if it determines that the vehicle is parked normally.

[0081] Specifically, the first execution unit or the second execution unit is used to disconnect the vehicle power supply, specifically including:

[0082] Disconnect the excitation circuit of the excitation generator to stop the excitation generator from generating electricity;

[0083] Disconnect all vehicle electrical equipment from the battery.

[0084] See Figure 3 As shown, this invention uses an excitation generator as the generator. The normally open contact of relay S1 in the excitation circuit of the excitation generator is opened, and the normally closed contact is closed, causing the excitation generator to stop generating electricity. The vehicle's electrical equipment is also disconnected from the battery, specifically by disconnecting the switch S2 built into the parking device of the hazardous materials transport vehicle.

[0085] Figure 3 In the process, the relay S1 in the excitation circuit of the excitation generator G is controlled by the parking device of the hazardous materials transport vehicle. When generating electricity normally, the normally open contact of the control relay S1 is closed and the normally closed contact is opened, and the excitation generator G is normally excited and generates electricity to the vehicle's electrical equipment or battery. When it is not necessary to generate electricity, the normally open contact of the control relay S1 is opened and the normally closed contact is closed, and the excitation generator G is not excited. Even if the excitation generator G rotates, it will not generate electricity, and the entire vehicle loses power supply. Compared with traditional generators, the power outage is more thorough.

[0086] The second execution unit is used to disconnect the vehicle power supply, activate the emergency call device, and send an emergency call signal to the emergency call recipient if it determines that the vehicle is abnormally stopped.

[0087] Specifically, the second execution unit is used to activate the rescue call device and send a rescue call signal to the rescue recipient through the rescue call device, specifically including:

[0088] Turn on the microphone, speaker, and wireless communication module of the emergency call device;

[0089] The wireless communication module continuously sends rescue call signals to the rescue recipient at preset intervals.

[0090] See Figure 2 As shown, the emergency call device is equipped with a microphone, speaker, and wireless communication module (from right to left). When an abnormal vehicle stop is detected, the vehicle's power is disconnected, and the battery built into the hazardous materials transport vehicle's parking device is used as a backup power source. The microphone, speaker, and wireless communication module of the emergency call device are then activated. The hazardous materials transport vehicle's parking device can continuously send emergency call signals to the rescue recipient (which can be a rescue organization or rescue platform) at preset intervals via the wireless communication module. The microphone and speaker, once activated, can be used by the driver or passengers to contact the rescue organization.

[0091] The hazardous materials transport vehicle parking device in this embodiment of the invention first acquires the vehicle's parking parameter values, then determines whether the vehicle is parking normally based on these values, and finally disconnects the vehicle's power supply based on the determination, or, based on disconnecting the vehicle's power supply, activates the emergency call device and sends an emergency call signal to the emergency responder. This invention can automatically disconnect the vehicle's power supply when a hazardous materials transport vehicle is parked and can send an emergency call signal in case of abnormal parking, thus improving safety.

[0092] It should be noted that those skilled in the art will clearly understand that, for the sake of convenience and brevity, the specific working process of the above-described device and each unit can be referred to the corresponding process in the aforementioned embodiments of the dangerous goods transport vehicle parking method, and will not be repeated here.

Figure 5The structure shown is merely a block diagram of a portion of the structure related to the present invention and does not constitute a limitation on the computer device to which the present invention is applied. A specific computer device may include more or fewer components than those shown in the figure, or combine certain components, or have different component arrangements.

[0096] A processor can be a CPU, or other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, or discrete hardware components. A general-purpose processor can be a microprocessor, or any conventional processor. The processor is the control center of a computer device, connecting all parts of the computer device through various interfaces and lines.

[0097] Memory can be used to store computer programs and / or modules. The processor implements various functions of the computer device by running or executing the computer programs and / or modules stored in the memory, and by accessing data stored in the memory. Memory can mainly include a program storage area and a data storage area. The program storage area can store the operating system, at least one application program required for a function (such as video playback, image playback, etc.), etc.; the data storage area can store data created based on the use of the mobile phone (such as video data, image data, etc.). In addition, memory can include high-speed random access memory, and can also include non-volatile memory, such as hard disks, RAM, plug-in hard disks, SmartMedia Cards (SMC), Secure Digital Cards (SD cards), Flash Cards, at least one disk storage device, flash memory device, or other volatile solid-state storage devices.

[0098] In one embodiment, the processor is configured to run a computer program stored in memory to perform the following steps:

[0099] Step S10: Obtain the parking parameter values ​​of the vehicle; the parking parameter values ​​are the vehicle body acceleration value or the seat belt acceleration value.

[0100] Specifically, see Figure 2As shown, an acceleration sensor can be installed on the vehicle body, and the controller in the instrument panel can obtain the vehicle's acceleration value when the vehicle is parked based on the parameters collected by the acceleration sensor. Alternatively, a force sensor can be installed on the seat belt, and the controller in the instrument panel can obtain the seat belt acceleration when the vehicle is parked based on the parameters collected by the force sensor.

[0101] Step S20: Determine whether the vehicle is parked normally based on the vehicle's parking parameter values;

[0102] Step S30: If it is determined that the vehicle is parked normally, disconnect the vehicle power supply;

[0103] Step S40: If it is determined that the vehicle is abnormally stopped, disconnect the vehicle power, turn on the emergency call device, and send an emergency call signal to the emergency call recipient.

[0104] As an optional implementation, in one embodiment of the invention, the step of determining whether the vehicle is parked normally based on the vehicle's parking parameter values ​​specifically includes:

[0105] Determine whether the parking parameter value is less than a preset parameter threshold;

[0106] If so, determine that the vehicle is parked normally;

[0107] If not, determine that the vehicle is parked abnormally.

[0108] Specifically, if the parking parameter value is the vehicle's acceleration value, it checks whether the acceleration value is less than a preset acceleration threshold. This is for the case of deceleration while parking, so the absolute value of the acceleration value is considered. For example, if the acceleration value is less than 6 m / s²... 2 This indicates a relatively smooth stop, which is a normal stopping condition. If the acceleration value is not less than 6 m / s², then... 2 (typically 10m / s) 2 The above indicates that a collision may have occurred, and the vehicle is parked abnormally.

[0109] If the parking parameter value is the parking seatbelt acceleration, it determines whether the parking seatbelt acceleration is less than a preset seatbelt acceleration threshold. For example, if the parking seatbelt acceleration is less than 0.8g, it indicates a relatively smooth stop, which is normal parking. If the parking seatbelt acceleration value is not less than 0.8g (usually above 2g), it indicates that a collision may occur, which is abnormal parking. It should also be noted that the preset parameter threshold can also be a range of values.

[0110] As an optional implementation, in one embodiment of the invention, activating the rescue call device and sending a rescue call signal to the rescue recipient through the rescue call device specifically includes:

[0111] Turn on the microphone, speaker, and wireless communication module of the emergency call device;

When an abnormal vehicle stop is detected, the vehicle's power is disconnected, and the battery built into the hazardous materials transport vehicle's parking device is used as a backup power source. The microphone, speaker, and wireless communication module of the emergency call device are then activated. The hazardous materials transport vehicle's parking device can continuously send emergency call signals to the rescue recipient (which can be a rescue organization or rescue platform) at preset intervals via the wireless communication module. The microphone and speaker, once activated, can be used by the driver or passengers to contact the rescue organization.

[0115] Disconnect the excitation circuit of the excitation generator to stop the excitation generator from generating electricity;

[0116] Disconnect all vehicle electrical equipment from the battery.

[0117] See Figure 3 As shown, this invention uses an excitation generator as the generator. The normally open contact of relay S1 in the excitation circuit of the excitation generator is opened, and the normally closed contact is closed, causing the excitation generator to stop generating electricity. The vehicle's electrical equipment is also disconnected from the battery, specifically by disconnecting the switch S2 built into the parking device of the hazardous materials transport vehicle.
