[0040] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0041] Current radiation monitoring equipment mainly focuses on radiation measurements in the local environment, and most radiation monitoring equipment currently on the market does not have a positioning function. However, in certain circumstances, such as national security considerations, the positioning systems of monitoring equipment on the market are mostly GPS, and there are fewer monitoring devices based on the Beidou positioning system. Or in many practical application scenarios, especially in urbanization management and environmental protection, old radiation monitoring equipment cannot provide location information and data transmission functions, and cannot meet the needs of intelligent supervision. At the same time, the replacement cost of old radiation monitoring equipment is high, and direct abandonment will result in the waste of old radiation monitoring equipment. Old radiation monitoring equipment refers to radiation monitoring equipment that does not have positioning and online data transmission functions and can only be used for local monitoring and viewing radiation monitoring data. Specifically, the data communication method of old equipment is mostly RS232.

[0042] In this regard, this embodiment provides a data transmission device, such as Figure 1 As shown, a data transmission device is connected to an old radiation monitoring device A, and the data transmission device includes:

[0043] The control module 10 is connected to the data output terminal of the old radiation monitoring device A and is used to periodically send control signals at a preset monitoring frequency and receive monitoring information sent by the old radiation monitoring device A. The control signals include measurement signals;

[0044] A relay module 40, wherein a first end of the relay module 40 is connected to the control module 10, and a second end of the relay module 40 is connected to a measurement button of the old radiation monitoring device. The relay module 40 is configured to generate a measurement instruction to the measurement button based on the control signal; the measurement instruction is used to control the old radiation monitoring device to respond to the measurement instruction and feedback monitoring information;

[0045] Beidou positioning module 20, which is connected to the control module 10 and is used to send location information of old radiation monitoring equipment;

[0046] The control module 10 is further configured to determine the monitoring information and the location information as monitoring location data and output the data;

[0047] The output module 30 receives the monitoring position data and outputs it.

[0048] It should be noted that the old radiation monitoring equipment A is a nuclear and radiation monitoring equipment that only has the radiation collection function.

[0049] Specifically, legacy radiation monitoring equipment refers to equipment that lacks positioning and online data transmission capabilities. The Beidou positioning module 20 uses the SR2631Z3 model, which offers improved accuracy compared to GPS positioning, ensuring national security. Optionally, the Beidou positioning module 20 uses the NEMA protocol for satellite communication.

[0050] Specifically, the control module 10 and the Beidou positioning module 20 are each connected to the legacy radiation monitoring device A. The Beidou positioning module 20 can collect the location information of the legacy radiation monitoring device A in real time and transmit this location information to the control module 10 via a preset communication method. Alternatively, the Beidou positioning module 20 can obtain the location information of the current device in real time. The Beidou positioning module 20 receives control signals periodically transmitted at a preset monitoring frequency and outputs the location information of the legacy radiation monitoring device.

[0051] Specifically, the control module 10 receives monitoring information transmitted by the legacy radiation monitoring device A via a pre-set communication method. The monitoring information is the radiation information collected by the legacy radiation monitoring device A. The control module 10 associates the positioning information with the monitoring information, packaging the positioning information and the monitoring information for integration. Optionally, the control module 10 is a microcontroller, specifically an STM32F103C8T6. It is worth noting that the format of the monitoring information transmitted by the legacy radiation monitoring device A and the monitoring location data output by the control module 10 are different.

[0052] Specifically, the control module 10 controls the measurement button of the legacy radiation monitoring device A through the relay module 40. Based on the measurement signal, the relay module 40 outputs a measurement command to the legacy radiation monitoring device A. After receiving the measurement command, the legacy radiation monitoring device A transmits the monitoring information to the control module 10, implementing automatic control functions, including automatic measurement of the monitoring information. This eliminates the need to replace the legacy radiation monitoring device A, significantly extending the service life of the existing equipment and preserving its original investment value. Furthermore, the addition of automatic control functionality improves the intelligence of the legacy radiation monitoring device A without requiring any modifications.

[0053] It's important to note that when designing an automatic data transmission system for older radiation monitoring equipment, a relay module was added to control the opening and closing of buttons on the older equipment, enabling these devices to automatically transmit data to the receiving end. This not only improves the intelligence level of older radiation monitoring equipment but also allows them to connect to modern communication systems without requiring major modifications, further reducing upgrade costs.

[0054] Specifically, the output module 30 can be a preset monitoring platform, thereby sending the monitoring location data to the preset monitoring platform for convenient viewing by the user. The output module 30 can also be a display device, thereby displaying the monitoring location data for convenient viewing by the user.

[0055] Furthermore, it should be noted that after receiving the monitoring signal from the old radiation monitoring device A, the control module 10 outputs it via the output module 30. This information can also be sent via wireless communication to a pre-set monitoring and early warning platform. The monitoring and early warning platform can adjust the data reporting frequency of other devices based on the monitoring information from the current device, sending instructions to other devices via wireless communication to increase or decrease the sampling frequency of their monitoring information. Using an adaptive algorithm, when a device's radiation exceeds the standard monitoring value, the system calculates the dose field based on the device's location information and increases the monitoring frequency within the monitoring radius of that monitoring point.

[0056] The present invention provides a data transmission device that connects to an old radiation monitoring device A, a Beidou positioning module 20, and an output module 30 via a control module 10, and connects to the control module 10 and the old radiation monitoring device A via a relay module 40. The control module 10 periodically sends control signals at a preset monitoring frequency, receives monitoring information and location information, determines monitoring location data based on the monitoring information and location information, and outputs it via the output module 30. This ensures compatibility between the positioning information and the data reporting platform without requiring large-scale hardware replacement of the old radiation monitoring device A. Furthermore, by eliminating the need to replace the old radiation monitoring device A, the service life of the existing equipment is greatly extended, the original investment value is preserved, and the substantial costs incurred by comprehensive hardware upgrades are effectively reduced.

[0057] The present invention provides a data transmission device that addresses the inability of traditional GPS positioning to meet specific requirements. This not only ensures that all monitoring data is accompanied by accurate location information, but also significantly improves the accuracy and efficiency of nuclear and radiation environmental monitoring. Furthermore, the improved Beidou positioning module 20 built into the data transmission device of the present invention is particularly important for scenarios requiring high-precision location information, such as rapidly locating potential risk sources or conducting detailed environmental impact assessments.

[0058] In some optional embodiments, such as Figure 4 As shown, the old radiation monitoring equipment also includes: a reset button R and an output button O, the control signal includes: a reset signal and an output signal, and the relay module includes:

[0059] A first relay 41, wherein a first end of the first relay 41 is connected to the control module 10, and a second end of the first relay 41 is connected to the reset button R. The first relay 41 is configured to receive a reset signal and generate a reset instruction to the reset button R. The reset button R is configured to reset the old radiation monitoring device A;

[0060] A second relay 42, wherein a first end of the second relay 42 is connected to the control module 10, and a second end of the second relay 42 is connected to the measurement button M. The second relay 42 is configured to generate a measurement instruction after receiving a measurement signal;

[0061] The third relay 43, the first end of the third relay 43 is connected to the control module 10, the second end of the third relay 43 is connected to the output button O, the third relay 43 is used to generate an output instruction after receiving the output signal, and the output instruction is used to control the old radiation monitoring equipment A to output monitoring information.

[0062] Specifically, when the control module 10 outputs the reset signal, the first square wave signal is outputted through the first pin PB13 of the control module 10 to control the first relay 41 , thereby activating the reset button R to control the old radiation monitoring device A to reset.

[0063] Specifically, when outputting the measurement signal, the control module 10 outputs a second square wave signal through the second pin PB14 of the control module 10 to control the second relay 42 , thereby activating the measurement button M to control the old radiation monitoring device A to start measurement.

[0064] Specifically, when outputting a signal, the control module 10 outputs a third wave signal through the third pin PB15 of the control module 10 to control the third relay 43 , thereby activating the measurement button O to control the old radiation monitoring device A to start outputting.

[0065] In some optional implementations, the Beidou positioning data transmission device further includes:

[0066] The level conversion circuit is connected to the control module 10 and the old radiation monitoring device A respectively, and is used to convert the level of the control signal output by the control module into a control signal that can be recognized by the old radiation monitoring device.

[0067] Specifically, the data communication method of legacy radiation monitoring device A is mostly RS232, which is converted to microcontroller-compatible levels through hardware level conversion circuits. To overcome compatibility issues between smart monitoring devices from different manufacturers, the communication protocol and data format of legacy radiation monitoring device A were unified. This greatly simplifies the communication process between legacy radiation monitoring device A and the management platform, ensuring seamless collaboration among all devices and improving the stability and efficiency of the entire system.

[0068] In some optional embodiments, such as Figure 2 As shown, the output module 30 includes:

[0069] The communication unit 31 is connected to the control module 10 and the radiation monitoring platform respectively, and is used to receive the monitoring position data and send it to the radiation monitoring platform.

[0070] Specifically, the control module 10 sends the monitoring location data to the radiation monitoring platform based on the communication unit 31. Optionally, the communication unit 31 can be a 4G module. The radiation monitoring platform can be a monitoring and early warning emergency platform. Setting the output from the universal asynchronous receiver and transmitter (UART interface) via AT commands (a communication protocol used to control and configure various devices) sends the radiation monitoring data and Beidou positioning data to the nuclear and radiation monitoring equipment management platform.

[0071] It's important to note that the use of 4G communication technology enables automatic data reporting, overcoming the limitations of legacy radiation monitoring equipment, which cannot directly transmit data to the monitoring platform. This allows users to receive real-time information from various monitoring points, significantly enhancing emergency response and handling capabilities. Furthermore, since this solution requires only the addition or modification of a small number of modules to achieve this functionality, it is highly cost-effective and easy to implement, mitigating the high costs associated with large-scale hardware replacement.

[0072] It should also be noted that the control module 10 receives the control signal sent by the radiation monitoring platform, and after further adjusting the monitoring position data, outputs it to the radiation monitoring platform through the communication unit 31, so that the control module 10 sends the monitoring position data that meets the requirements of the radiation monitoring platform.

[0073] In addition, the data transmission device may also include an operation monitoring module, which is connected to the working line of the old radiation monitoring device A, so as to monitor various working states of the old radiation monitoring device A and notify the user of timely maintenance.

[0074] In some optional embodiments, such as Figure 2 As shown, the output module 30 further includes:

[0075] The display unit 32 is connected to the control module 10 and is used to display the monitoring position data.

[0076] Specifically, the control module 10 sends the monitoring position data to the display unit 32, and the display unit 32 displays the monitoring position data. Optionally, the display unit 32 can be an OLED (Organic Light-Emitting Diode).

[0077] In some optional embodiments, such as Figure 3 As shown, the Beidou positioning module 20 and the control module 10 are connected in communication based on the asynchronous receive and transmit transmission protocol;

[0078] The control module 10 is in communication connection with the old radiation monitoring device A based on the asynchronous receive and transmit transmission protocol.

[0079] Specifically, the asynchronous receive and transmit transmission protocol is UART, refer to Figure 3 The old radiation monitoring device A sends a monitoring signal to the fourth pin RX2 of the control module 10 through TX, and receives the information sent by the control module 10 through RX when the third pin TX2 of the control module 10 sends information.

[0080] Specifically, the Beidou positioning module 20 sends a positioning signal to the sixth pin RX3 of the control module 10 through the third pin TX, and receives information through the fourth pin RX when the fifth pin TX3 of the control module 10 sends information.

[0081] Specifically, the fourth pin TX of the communication unit 31 is connected to the first pin TX1 of the control module 10 , and the fifth pin RX of the communication unit 31 is connected to the second pin RX1 of the control module 10 .

[0082] Specifically, the seventh pin SDA of the control module 10 is connected to the SDA of the display unit 32 , and the seventh pin SCL of the control module 10 is connected to the SCL of the display unit 32 .

[0083] In some optional implementations, the location information of the old radiation monitoring equipment is Beidou positioning information;

[0084] After receiving the Beidou positioning information, the control module 10 is used to obtain longitude and latitude information based on the longitude field and latitude field between the preset comma strings in the character string of the Beidou positioning information, and use the longitude and latitude information as the location information.

[0085] Specifically, Beidou positioning information is a command. The command format of the NEMA protocol is as follows:

[0086] $BDRMC,023656.00,A,2240.61563,N,11359.86512,E,0.16,140324,A,V*2C

[0087] After receiving the instruction, the control module 10 locates the character string containing the comma character, records the number of commas and the character string position of each comma, obtains the longitude field between the first and second preset commas, and obtains the latitude field between the third and fourth preset commas. The longitude field and latitude field are stored in the preset longitude and latitude fields, respectively. The longitude and latitude fields are then converted to numeric values, namely degrees and minutes, and the decimal latitude and longitude information is obtained by adding the degrees and minutes.

[0088] For example, if the first preset comma is the third comma and the second preset comma is the fourth comma, the longitude information obtained is 2240.61563. If the third preset comma is the fifth comma and the fourth preset comma is the sixth comma, the longitude information obtained is 11359.86512.

[0089] degree=2240.61563 / 100

[0090] minute=(2240.61563-degree*100) / 60

[0091] information=degree+minute

[0092] In some optional embodiments, such as Figure 2 As shown, the data transmission device also includes:

[0093] The clock module 50 is connected to the control module 10 and is used to provide clock information to the control module 10 .

[0094] Specifically, the clock module 50 can calculate seconds, minutes, hours, days, weeks, months, and years. It can also add corresponding time information during data transmission to facilitate subsequent data analysis and processing. In other words, the control module 10 packages the time information, monitoring information, and location information together for transmission. Optionally, the clock module 50 is specifically designed as a DS1302.

[0095] Based on the aforementioned radiation monitor, the radiation monitor includes multiple data transmission devices as described above. Each of the multiple data transmission devices is connected to multiple legacy radiation monitoring devices. Consequently, multiple legacy radiation monitoring devices are simultaneously connected to the radiation monitoring platform. The radiation monitoring platform controls multiple legacy radiation monitoring devices simultaneously through the multiple data transmission devices. Specifically, the platform can control multiple legacy radiation monitoring devices to transmit monitoring information at a preset frequency. This achieves compatibility of positioning information and output without requiring large-scale hardware replacement of legacy radiation monitoring devices A. Furthermore, by eliminating the need to replace legacy radiation monitoring devices A, the service life of existing equipment is greatly extended, preserving the original investment value and effectively reducing the substantial costs associated with a comprehensive hardware upgrade.

[0096] Based on the aforementioned radiation monitoring system, the radiation monitoring system includes the aforementioned radiation monitors and a radiation monitoring platform. The radiation monitoring platform is communicatively connected to the control module of each data transmission device and is configured to adjust the preset monitoring frequency based on monitoring location data and preset thresholds. The radiation monitoring platform can adjust the measurement frequencies of multiple older radiation monitoring devices A based on the received monitoring location data. This contributes to the establishment of a comprehensive and efficient national nuclear and radiation safety regulatory system. By increasing the value of existing equipment, extending its lifecycle, and providing it with modern functional features, not only can resources be utilized more efficiently, but the reliability and flexibility of the overall system can also be significantly improved. This has immeasurable significance for safeguarding public health, protecting environmental safety, and promoting scientific and technological advancement in national nuclear and radiation safety management.

[0097] Specifically, the MQTT (Message Queuing Telemetry Transport) protocol can be used between the control module and the monitoring and early warning platform to establish a connection between different legacy radiation monitoring devices and the platform, thereby establishing a correlation between the monitoring frequencies of different legacy radiation monitoring devices. The control module 10 further transmits the monitoring location data to the preset monitoring and early warning platform via wireless communication. The monitoring and early warning platform can adjust the data reporting frequency of other legacy radiation monitoring devices A based on the monitoring information of the current device, and send instructions to other legacy radiation monitoring devices A via wireless communication to increase or decrease the monitoring information sampling frequency of other legacy radiation monitoring devices A. Using an adaptive algorithm, when the radiation of legacy radiation monitoring device A exceeds the conventional monitoring value, the system performs dose field calculations based on the positioning information of the legacy radiation monitoring device A and increases the monitoring frequency of the monitoring radius of the monitoring point.

[0098] In summary, the present invention not only greatly improves the efficiency and accuracy of nuclear and radiation environmental supervision, but also lays a solid foundation for establishing a more scientific and efficient national nuclear and radiation safety protection system through low-cost upgrades and renovations while ensuring the investment value of the original equipment.

[0099] In some optional embodiments, the data transmission device of the radiation monitoring apparatus is connected to an old radiation monitoring device.
