[0002] With the acceleration of urbanization, high-rise buildings and their ancillary facilities such as underground parking lots are becoming more and more common. Underground parking lots are prone to radon gas accumulation due to their closed nature and the possible presence of radioactive substances in building materials. Radon is a colorless and odorless radioactive gas. Long-term exposure to high concentrations of radon can have serious effects on human health, especially damage to the respiratory system. Therefore, monitoring the environmental nuclear radiation dose rate in confined spaces such as underground parking lots is crucial to ensure people's life safety.

[0003] Existing environmental nuclear radiation dose rate measurement equipment mainly includes handheld Geiger counters and handheld semiconductor detectors. These devices usually require users to carry them with them and manually start the measurement process when needed, and then wait to read the measurement results. This method has obvious limitations, such as poor portability of the equipment, complex operation, and inability to realize remote monitoring and real-time alarm functions. Especially in emergency situations, this reliance on manual operation may delay the best time to take necessary protective measures. Summary of the invention

[0020] Figure 2 The present invention is a flow chart of a method for measuring and protecting nuclear radiation dose rate in a vehicle environment. DETAILED DESCRIPTION

[0021] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] The present invention provides Figure 1 A vehicle environment nuclear radiation dose rate measurement and protection system is shown, the system includes the following components: environment nuclear radiation intensity sensor RS, seat pressure sensor, window actuator, air conditioning and ventilation actuator, body control unit BCM, cockpit screen, cockpit audio, cockpit control unit CDC, remote communication terminal Tbox, intelligent driving control unit ADC, cloud server, mobile phone application;

[0023] The environmental nuclear radiation intensity sensor is integrated in the vehicle body control unit and is used to detect the intensity of gamma radiation in the environment; the environmental nuclear radiation intensity sensor RS is responsible for detecting the intensity value of gamma radiation in the environment. The present invention uses a gamma-ray nuclear radiation dose detection chip as an environmental nuclear radiation intensity sensor, model CRD1503G of China National Nuclear Corporation, with an operating temperature range of -20°C to 50°C, a power consumption of about 1mW, and a range of 100nSV / h to 10mSV / h. When used for environmental background radiation measurement, continuous and stable readings can be obtained in about 1 minute.

[0024] The working principle is: when gamma rays (essentially gamma photons with extremely high energy) hit the sensitive volume inside the nuclear radiation dose detection chip (sensitive volume refers to a semiconductor area inside the chip that is specifically used to receive radiation impact), there is a certain probability that the semiconductor nuclei or electrons in the sensitive volume will be ionized or excited. The gamma photons will lose energy in this process, and the lost energy is converted into hundreds or thousands of electron-hole pairs or scintillation photons. The photoelectric conversion circuit in the nuclear radiation dose detection chip converts and amplifies the energy generated by these ionizations, and then converts it into a digital pulse signal for measurement through the analog-to-digital conversion circuit in the chip. By counting the number of pulse signals, the number of gamma photons received can be known, which reflects the intensity of the gamma rays.

[0025] The body control unit is used to receive the gamma radiation intensity value detected by the environmental nuclear radiation intensity sensor and forward the value to the cockpit control unit; the cockpit control unit is used to process the received gamma radiation intensity value, and when the value exceeds the set threshold, send a warning message to the cloud server through the remote communication terminal; the cloud server is used to record the gamma radiation intensity value and push the warning message to the mobile phone application; the mobile phone application is used to receive and display the warning message.

[0026] The body control unit BCM is a common component in many modern vehicles, which includes a main control chip and other necessary auxiliary components and circuits for the related logic control of various sensors and actuators of the body. On the basis of the conventional BCM, the present invention integrates the aforementioned environmental nuclear radiation intensity sensor RS on the hardware circuit board of the BCM, and the data and control pins of the environmental nuclear radiation intensity sensor RS are connected to the corresponding pins of the main control chip of the BCM, so that the BCM can configure the working state of the environmental nuclear radiation intensity sensor RS and read the environmental nuclear radiation intensity value detected by the environmental nuclear radiation intensity sensor RS.

[0027] The present invention adds the following functions to BCM: 1. Forwarding the environmental nuclear radiation intensity value measured by the environmental nuclear radiation intensity sensor RS to the cockpit control unit CDC; 2. Receiving instructions from the cockpit control unit CDC, controlling the window actuator to lower the window and controlling the air-conditioning and ventilation actuator to turn on the external circulation ventilation mode to ventilate the passenger compartment to reduce the radon gas concentration; 3. Real-time collection of seat pressure values ​​sent by each seat pressure sensor in the passenger compartment, judging whether there are drivers and passengers in the car, and notifying the cockpit control unit CDC of the judgment result.

[0028] The seat pressure sensor is used to detect whether there are any passengers in the vehicle. The cockpit control unit decides whether to issue a warning message based on the detection result of the seat pressure sensor. The seat pressure sensor is located under the seat cushions of each seat in the passenger compartment. It can convert the pressure signal of 10kPa to 400kPa into an analog signal with a customizable output range (0~5V), and is connected to the body control unit BCM through ordinary wire cables.

[0029] The window actuator and the air conditioning and ventilation actuator, when the cabin control unit detects that the gamma radiation intensity value exceeds the set threshold, controls the window actuator and the air conditioning and ventilation actuator through the body control unit to improve the air quality in the passenger compartment. The window actuator is located in each door with movable windows, connected to the body control unit BCM through ordinary wire cables, and receives the PWM (Pulse Width Modulation) signal of the BCM for lifting and lowering the window; the air conditioning and ventilation actuator is located in the vehicle air conditioning and ventilation system, connected to the body control unit BCM through ordinary wire cables, and receives the PWM (Pulse Width Modulation) signal of the BCM for switching between internal and external circulation and controlling the fan gear.

[0030] In the present invention, the body control unit BCM and the cockpit control unit CDC are connected via an in-vehicle Ethernet.

[0031] The cockpit control unit uses the sliding average method to process the received gamma radiation intensity value. The algorithm formula is as follows: Vb = (Val + Va2 + Va3 + Va4 + Va5) / 5, Va is the environmental nuclear radiation intensity value, and Vb is the sliding average value.

[0032] The cockpit control unit CDC includes a main control chip and other necessary auxiliary components and circuits for the human-machine interaction logic control of the passenger compartment. The present invention adds the following functions to the CDC: 1. Receive the environmental nuclear radiation intensity value forwarded by the body control unit BCM and perform smoothing, connect to the network through the remote communication terminal Tbox and send the smoothed environmental nuclear radiation intensity value to the cloud server; 2. Receive the occupant status reported by the body control unit BCM; 3. According to whether the smoothed environmental nuclear radiation intensity value exceeds the warning value, combined with the occupant status, decide to display relevant prompts through the cockpit screen and issue voice reminders through the cockpit audio, or connect to the cloud server through the remote communication terminal Tbox to push notification messages to the driver and passenger mobile phone application; 4. Receive the cloud remote call command, notify the intelligent driving control unit ADC to start remote call intelligent driving; 5. Receive the intelligent driving control unit ADC remote call intelligent driving end notification, notify the body control unit BCM to ventilate the passenger compartment.

[0033] The cockpit screen is located in the passenger compartment and is connected to the cockpit control unit CDC through the MIPI-DSI (Mobile Industry Processor Interface-Display Bus Interface) interface. It is used to display text and graphic prompts to the driver and passengers. There are one or more screens.

[0034] The cockpit audio system is located in the passenger compartment and is connected to the cockpit control unit CDC via ordinary wire cables. It is used to play voice reminders to the driver and passengers. There are one or more of them.

[0035] In the present invention, the cockpit control unit CDC and the remote communication terminal Tbox are connected via an in-vehicle Ethernet.

[0036] The remote communication terminal Tbox includes a main control chip, a radio frequency baseband chip, a GPS positioning chip and other necessary auxiliary components and circuits. The present invention relies on the Tbox to connect to the 4G / 5G network of the telecom operator, provide GPS positioning for the vehicle, and provide the cockpit control unit CDC with an Internet communication link connected to the cloud server.

[0037] The intelligent driving control unit ADC includes a main control chip, a visual camera, a radar sensor and other necessary auxiliary components and circuits, which are used for autonomous driving algorithm strategy calculation and driving logic control to achieve assisted driving or autonomous driving in various scenarios. The present invention relies on ADC to execute the remote call intelligent driving function of the vehicle and report the intelligent driving status to the cockpit control unit CDC.

[0038] In the present invention, the intelligent driving control unit ADC and the cockpit control unit CDC are connected via an in-vehicle Ethernet.

[0039] The cloud server, including server hardware and corresponding background software, is usually provided by the vehicle manufacturer to support the Internet of Vehicles function. It uses the public technology TLS (Transport Layer Security) protocol to achieve secure encrypted connections between the cloud server and the vehicle-side cockpit control unit CDC, as well as between the cloud server and the mobile application. It protects all HTTP (Hypertext Transfer Protocol) communications between the vehicle and the cloud, and between the cloud and the mobile phone, including vehicle registration and identity binding, identity authentication, data and command transmission, etc. It is a public technology.

[0040] The present invention adds the following functions to the background software of the cloud server: 1. When a vehicle reports an environmental nuclear radiation intensity value, the value is recorded in the memory of the cloud server; 2. When a mobile phone application requests to query the current or past environmental nuclear radiation intensity value, the corresponding recorded value is read from the memory of the cloud server and sent to the mobile phone application; 3. When a vehicle reports a notification message that the environmental nuclear radiation intensity value exceeds the warning value, the cloud server forwards the notification message to the mobile phone application; 4. When a user issues a remote summoning command through the mobile phone application, the cloud server forwards the command to the vehicle end.

[0041] The mobile phone application is a software component installed in the mobile phone of the driver and passenger for communicating with the cloud server, which belongs to the public technology. The present invention adds the following functions to the mobile phone application: 1. Support users to query the current and historical environmental nuclear radiation intensity values ​​of the bound vehicle from the cloud server; 2. Receive the abnormal reminder notification of the environmental nuclear radiation intensity value pushed by the cloud server; 3. When the user chooses to use the remote summoning function, the remote summoning instruction is sent to the vehicle through the cloud server.

[0042] In summary, the present invention proposes a vehicle environment nuclear radiation dose rate measurement and protection system, which uses a gamma-ray nuclear radiation dose detection chip as an environmental nuclear radiation intensity sensor, and the sensor is integrated into the vehicle electronic system. The system can realize automatic non-sensing measurement; can automatically make decisions based on the measurement results, and achieve protection effects through the cooperation of multiple components; and can connect to the network for communication.

[0043] like Figure 2 As shown, Figure 2 The present invention is a flow chart of a method for measuring and protecting nuclear radiation dose rate in a vehicle environment.

[0044] In this embodiment, a method for measuring and protecting a vehicle environment nuclear radiation dose rate includes the following steps:

[0045] 1. Preset and configure the working parameters of the γ-ray nuclear radiation dose detection chip RS in the body control unit BCM, activate the γ-ray nuclear radiation dose detection chip RS to put it into the measurement state.

[0046] 2. The gamma-ray nuclear radiation dose detection chip RS begins to periodically send the measurement result value Va to the body control unit BCM.

[0047] 3. The body control unit BCM forwards the received environmental nuclear radiation intensity value Va to the cockpit control unit CDC.

[0048] 4. In order to solve the problem of false alarms caused by large fluctuations in the measured environmental nuclear radiation intensity value due to accidental factors, the cockpit control unit CDC uses a simple sliding average method for the received environmental nuclear radiation intensity value Va, and calculates the sliding average value Vb within the past time window (the present invention takes the time window as 5, that is, the most recent 5 measurement readings) as the smoothed environmental nuclear radiation intensity value. The algorithm formula is as follows: Vb = (Va1 + Va2 + Va3 + Va4 + Va5) / 5

[0049] 5. The cockpit control unit CDC will package the data including the latest calculated sliding average value Vb and other necessary data (such as vehicle identification code, date and time, GPS positioning information, etc.), and send it to the cloud server through the remote communication terminal Tbox, and the cloud server will record it. Vehicle drivers and passengers can view the most recent environmental nuclear radiation intensity value Vb recorded by the vehicle through the application on their mobile phones. If the user agrees to join the sharing plan, the environmental nuclear radiation measurement results of the parking lot will be shared with other vehicle users (after removing the privacy information of the vehicle and the driver and passengers), and the environmental nuclear radiation intensity values ​​of other parking lots shared by other users' vehicles can also be viewed.

[0050] 6. The cockpit control unit CDC determines whether the value Vb of the environmental nuclear radiation intensity exceeds the warning limit of the environmental nuclear radiation intensity specified by the environmental protection department: if it does not exceed the limit, no processing is done and the next measurement data is waited for; if it exceeds the limit, the body control unit BCM is queried about the occupant status of each seat to determine whether there are any drivers or passengers in the current vehicle: if there are drivers or passengers, a warning prompt containing the value Vb of the current environmental nuclear radiation intensity is displayed on the cockpit screen, and a voice reminder is played through the cockpit audio system, suggesting that the drivers and passengers leave the area as soon as possible and increase ventilation. If there are no drivers or passengers, a message that the value of the environmental nuclear radiation intensity exceeds the standard is sent to the cloud server through the remote communication terminal Tbox.

[0051] 7. After the cloud server receives the message that the environmental nuclear radiation intensity exceeds the standard, it will push the message notification to the mobile phone application of the vehicle driver and passengers.

[0052] 8. Vehicle drivers and passengers can view messages about excessive environmental nuclear radiation intensity pushed by the application on their mobile phones.

[0053] 9. Before the driver or passenger plans to go to the parking lot to pick up the car and leave, they can decide whether to pick up the car by selecting the remote call function in the mobile phone application or go to the parking lot in person to pick up the car. If the driver or passenger chooses the remote call function to pick up the car, the cloud server sends a remote call command to the cockpit control unit CDC through the remote communication terminal Tbox; if the driver or passenger does not choose the call function to pick up the car, when the driver or passenger enters the passenger compartment, the cockpit control unit CDC detects that the driver or passenger is seated through the body control unit BCM, and then displays a warning prompt containing the current environmental nuclear radiation intensity value Vb on the cockpit screen, and plays a voice reminder through the cockpit audio, suggesting that the driver or passenger leave the area as soon as possible and increase ventilation.

[0054] 10. After the cockpit control unit CDC receives the remote summoning command requested by the driver and passengers, it requests the intelligent driving control unit ADC to start the remote summoning intelligent driving process.

[0055] 11. The intelligent driving control unit ADC takes the location designated by the driver and passengers as the destination and starts intelligent driving navigation.

[0056] 12. When the vehicle arrives at the location designated by the driver and passengers, the intelligent driving control unit ADC will feedback to the cockpit control unit CDC that the remote summoning intelligent driving process has been completed.

[0057] 13. The cockpit control unit CDC confirms that the remote summoning intelligent driving process is completed and notifies the body control unit BCM to ventilate the passenger compartment.

[0058] 14. The body control unit BCM controls the window actuator to lower the window and controls the air conditioning and ventilation actuator to turn on the external circulation ventilation mode.

[0059] In summary, the present invention proposes a vehicle environment nuclear radiation dose rate measurement and protection method, which allows the driver and passengers to remotely obtain the value of the environment nuclear radiation intensity at the location of the vehicle; when the value of the environment nuclear radiation intensity at the location of the vehicle exceeds the safety limit, the driver and passengers can be notified in time. The driver and passengers can choose to let the vehicle automatically drive to a relatively safe location for environmental nuclear radiation before getting on the vehicle, and automatically ventilate.

[0060] In addition, the measurement and protection system of the present invention is installed in the vehicle as a component of the vehicle-mounted electronic system, and does not need to be carried separately or charged separately. The measurement and protection system of the present invention is driven by the vehicle-mounted electronic system software, does not require human intervention, and does not need to wait for the measurement results on site, thus realizing automatic and non-sensing operation.

[0061] The measurement and protection system of the present invention can be connected to the network and transmit the measurement results through the network. The driver and passengers can view the real-time environmental nuclear radiation intensity value through the mobile phone application. With the permission of the driver and passengers, the environmental nuclear radiation measurement results of the parking lot can be shared with other vehicle users, so that other vehicle users can understand the environmental nuclear radiation levels of each parking lot in advance and make better parking plan decisions.

[0062] The measurement and protection systems described in the present invention can work in conjunction with each other. For example, when a continuous high radiation intensity is measured, it is recommended that the driver and passengers wait on the ground floor, without entering the underground parking lot to drive or ride the vehicle. The intelligent driving control unit will be responsible for automatically driving the vehicle to the ground floor to wait for the driver and passengers to get on the vehicle. At the same time, it can also automatically lower the windows after leaving the underground parking lot, start the air conditioning external circulation, and ventilate the passenger compartment to remove radon pollution; for example, when the nuclear radiation intensity of the parking environment is measured to be high, a text prompt will be displayed on the cockpit screen, supplemented by a voice broadcast reminder, reminding the driver and passengers to pay attention to the abnormal nuclear radiation intensity of the environment and recommending them to leave as soon as possible.

[0063] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
