Technical Field

[0001] This utility model relates to the field of radiation monitoring technology, specifically to a positioning data transmission device. Background Technology

[0002] Current radiation safety and environmental monitoring work relies heavily on outdated radiation monitoring equipment, such as various radiation detectors, inspection instruments, surface contamination meters, and radon meters. While these devices retain their core measurement functions, their early design often results in numerous defects. They are largely limited in function, primarily providing local measurement and display, lacking network communication capabilities, and thus unable to upload monitoring data to a central management platform in real time, creating "data silos." This hinders regulatory authorities from conducting centralized, dynamic, and real-time effective monitoring, leading to slow emergency response times.

[0003] If all these old devices, which still have some functionality but lack network positioning capabilities, are replaced with new integrated smart devices, it will result in huge financial expenditures and a serious waste of existing fixed assets.

[0004] Therefore, the market urgently needs a cost-effective, highly compatible solution that can intelligently upgrade and transform existing outdated equipment. Utility Model Content

The control module controls the indicator light to turn on or off to indicate the power status, system operating status, or communication status.

[0018] In one optional embodiment, the positioning data transmission device further includes a power supply and a power supply monitoring module.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] In current radiation safety and environmental monitoring work, there are a large number of outdated radiation monitoring devices in service. These devices have limited functionality and generally suffer from the following defects:

[0036] 1. Isolated functions and inability to connect to the network: Most devices are for local measurement and display, lacking network communication capabilities and unable to upload monitoring data to the central management platform in real time, creating "data silos." This prevents regulatory authorities from conducting centralized, dynamic, and real-time effective monitoring, resulting in slow emergency response.

[0037] 2. Lack of positioning and inability to trace the source: Most older equipment lacks positioning modules, especially the BeiDou positioning system which meets national security requirements. When mobile monitoring is conducted or abnormal events occur, the geographical location of data collection cannot be accurately recorded, posing significant challenges to risk tracing and environmental assessment.

[0038] 3. Inconsistent interfaces make integration difficult: Different brands and models of equipment have different data export methods, such as RS232 and RS485 serial interfaces. Some equipment even uses non-standard methods, such as multi-functional radiation measuring instruments that use infrared optical ports. This results in poor compatibility and high technical difficulty in unifying these heterogeneous devices into a modern management platform.

[0039] 4. High replacement costs and waste: If all these old devices with decent functions but lacking network positioning capabilities are replaced with new integrated smart devices, it will result in huge financial expenditures and a serious waste of existing fixed assets.

[0040] To address the problems of limited functionality, inability to network for location tracking, inconsistent interfaces, and high replacement costs associated with existing outdated radiation monitoring equipment, this utility model aims to provide a location data transmission device compatible with multiple interfaces. This device acts as an "external" smart adapter, solving the following technical problems: providing remote data transmission capabilities based on 4G / 2.4G cellular networks for outdated radiation monitoring equipment lacking remote data transmission functionality; integrating a location module into outdated equipment without location functionality, adding high-precision geographic location information to each monitoring data point; resolving compatibility issues between different radiation monitoring equipment data interfaces (such as RS232, RS485, infrared, etc.), enabling plug-and-play or simple adaptation access to various mainstream radiation monitoring instruments; and achieving intelligent upgrades of equipment in a low-cost and high-efficiency manner without replacing the original expensive core detection equipment, extending its service life and preserving investment value.

[0041] like Figure 1 As shown, this embodiment of the present invention provides a positioning data transmission device, comprising:

[0042] The data acquisition interface module is used to connect the target radiation monitoring equipment and the control module, and transmit the radiation monitoring data output by the target radiation monitoring equipment to the control module.

[0043] The data acquisition interface module is crucial for compatibility; it connects to the data output of the target radiation monitoring equipment to receive radiation monitoring data. The target radiation monitoring equipment consists of various outdated devices, such as those lacking remote data transmission or positioning capabilities, or whose corresponding functions are damaged. Radiation monitoring equipment includes radiation detectors, inspection instruments, surface contamination meters, and radon meters, among others.

[0044] The clock module is used to obtain the current time information and send it to the control module.

[0045] Specifically, such as Figure 6As shown, the clock module uses a high-precision real-time clock (RTC) chip such as the DS1302 to provide accurate time information to the control module. The clock module acquires the current time information in real time to ensure that each uploaded radiation monitoring data has a precise acquisition timestamp, facilitating subsequent data analysis and event tracing.

[0046] The positioning module is used to obtain the current positioning information and send it to the control module.

[0047] The positioning module can be a GPS module or a BeiDou positioning module. In a preferred embodiment, the positioning module uses a single BeiDou positioning module, such as the SR2631Z3 module. Figure 5 As shown, the single BeiDou positioning module is connected to the control module via a UART interface. After the single BeiDou positioning module is started, it automatically searches for satellites and locates itself, continuously outputting a positioning information string conforming to a standardized protocol, preferably the NMEA protocol. Upon receiving this string, the control module parses it using a built-in algorithm, extracting key fields such as longitude and latitude to obtain accurate current positioning information.

[0048] Unlike common GPS or hybrid positioning solutions on the market, this utility model adopts a single Beidou positioning module, which not only improves positioning accuracy but also meets the requirements of information security strategy, making it particularly suitable for application scenarios in sensitive departments such as science and technology and environmental protection.

[0049] The data transmission module is used to enable data communication between the control module and the monitoring terminal.

[0050] The control module is used to fuse radiation monitoring data, current location information, and current time information into a data packet, and then send the data packet to the monitoring terminal through the data transmission module.

[0051] like Figure 2 As shown, the control module uses a microcontroller, specifically an STM32 microcontroller. As the brain of the entire device, the control module is responsible for scheduling and managing the work of all other modules. It executes the firmware program and completes the entire process of data acquisition, parsing, packaging, display, and transmission.

[0052] After receiving radiation monitoring data from the target radiation monitoring equipment, the control module immediately obtains the current location information from the positioning module and the current time information from the clock module. Then, it integrates these three information into a standard format data packet in the format of "radiation monitoring data + current location information + current time information".

[0053] Monitoring terminals include cloud-based systems, private radiation monitoring platforms, or mobile devices.

[0054] The data transmission module can employ a cellular network communication module, a 2.4G wireless communication module, a Zigbee wireless communication module, etc. In one example, such as... Figure 8 As shown, the data transmission module uses a 4G cellular network communication module, which is connected to the control module via a UART interface. The control module sends AT commands to control the 4G cellular network communication module to dial, connect to the network, and establish a data link to the designated backend platform (e.g., via TCP / IP or MQTT protocols). After the connection is established, the control module sends the packaged data packets to the monitoring terminal via the 4G module.

[0055] This utility model discloses a positioning data transmission device that transmits radiation monitoring data output from a target radiation monitoring device to a control module via a data acquisition interface module. The current time and location information are acquired by a clock module and a positioning module, respectively. The control module merges the radiation monitoring data, current location information, and current time information into a data packet, which is then sent to the monitoring terminal via the data transmission module. This "plug-and-play" upgrade solution provides a plug-and-play external smart adapter. Users do not need to discard expensive, outdated radiation monitoring equipment; they only need to configure one positioning data transmission device for each outdated radiation monitoring device to achieve a full-function modernization upgrade, revitalizing fixed assets and saving over 90% of replacement costs.

[0056] By precisely matching the spatiotemporal coordinates of each measurement data point, the integrity and validity of the data are ensured. All monitoring records are verifiable and traceable, providing a high-quality data foundation for subsequent environmental assessments, dose calculations, and scientific research.

[0057] The data transmission module sends data packets containing radiation monitoring data, current location information, and current time information to the monitoring terminal. This enables real-time fusion and standardized encapsulation of these three data points from diverse sources, forming valuable, structured information directly applicable to big data analysis. This integrates previously scattered and isolated monitoring points into an organic, dynamic, and visualized monitoring network. Regulatory personnel can view the location and data of any front-end radiation monitoring device in real time on the central platform, achieving a shift from "passive inspection" to "proactive early warning," significantly improving the efficiency and accuracy of environmental supervision and nuclear emergency response.

[0058] In some embodiments, the data acquisition interface module includes an RS232 communication circuit. The RS232 communication circuit includes a first level conversion chip and an RS232 interface. The first level conversion chip is connected to the data transceiver terminal of the control module and the RS232 interface, respectively. It is used to convert the RS232 level signal input from the RS232 interface into a TTL level signal and output it to the control module. The RS232 interface is used to connect with the target radiation monitoring device to receive the RS232 level signal output by the target radiation monitoring device. The target radiation monitoring device transmits radiation monitoring data through the RS232 level signal.

[0059] The circuit schematic of the RS232 communication circuit is as follows: Figure 3 As shown, the first level conversion chip U5 uses a MAX3232 chip. The T1IN1 and R1OUT pins of the first level conversion chip U5 are connected to the data transceiver terminals TXD3 and RXD3 of the control module. The T1OUT and R1IN pins of the first level conversion chip U5 are connected to the RS232 interface P1. The target radiation monitoring device connects via an RS232 bus and an RS232 interface, transmitting its own radiation monitoring data to the first level conversion chip U5 via RS232 level signals. The first level conversion chip U5 converts the RS232 level signals into TTL level signals that the control module can recognize. The control module receives the TTL level signals through the UART port, i.e., the data transceiver terminals TXD3 and RXD3, to obtain the radiation monitoring data, thereby realizing data transmission between the control module and the target radiation monitoring device.

[0060] This utility model embodiment uses an RS232 communication circuit to realize data transmission between the control module and the target radiation monitoring equipment (such as a personal dosimeter) with a corresponding serial port, thereby enabling the positioning data transmission device to be used as an external device for the target radiation monitoring equipment, increasing the compatibility with the target radiation monitoring equipment.

[0061] In some embodiments, the data acquisition interface module includes an RS485 communication circuit. The RS485 communication circuit includes a second level conversion chip and an RS485 interface. The second level conversion chip is connected to the data transceiver terminal of the control module and the RS485 interface, respectively, and is used to convert the RS485 level signal input from the RS485 interface into a TTL level signal and output it to the control module. The RS485 interface is used to connect with the target radiation monitoring device to receive the RS485 level signal output by the target radiation monitoring device. The target radiation monitoring device transmits radiation monitoring data through the RS485 level signal.

[0062] The circuit schematic of the RS485 communication circuit is as follows: Figure 4As shown, the second level conversion chip U7 uses a MAX3485. The RO and DI pins of the second level conversion chip U7 are connected to the data transceiver terminals TXD3 and RXD3 of the control module, and the A and B pins of the second level conversion chip U7 are connected to the RS485 interface J3. The target radiation monitoring device is connected to the RS485 interface J3 via an RS485 bus, transmitting the radiation monitoring data it obtains to the second level conversion chip U7 via an RS485 level signal. The second level conversion chip U7 converts the RS485 level signal into a TTL level signal that the control module can recognize. The control module receives the TTL level signal through the UART port to obtain the radiation monitoring data, thereby realizing data transmission between the control module and the target radiation monitoring device.

[0063] This utility model embodiment uses an RS485 communication circuit to realize data transmission between the control module and the target radiation monitoring equipment with a corresponding serial port, thereby enabling the positioning data transmission device to be used as an external device for the target radiation monitoring equipment, increasing the compatibility with the target radiation monitoring equipment.

[0064] By using RS232 and RS485 communication circuits, the positioning data transmission device supports RS232 / RS485 standard industrial serial ports, increasing compatibility with target radiation monitoring equipment.

[0065] In some embodiments, the first level conversion chip can be used with an external infrared adapter to receive infrared signals output by the target radiation monitoring device through the infrared port and convert the received infrared signals into RS232 level signals. The first level conversion chip converts the RS232 level signals input by the infrared adapter into TTL level signals and outputs them to the control module. The target radiation monitoring device transmits radiation monitoring data through infrared signals.

[0066] Specifically, the first level conversion chip is used in conjunction with an infrared adapter. The infrared adapter can receive the infrared signal output by the target radiation monitoring device (such as the FH40G radiation detector) through the infrared port, and work with the first level conversion chip to convert the infrared signal into a TTL level signal that the control module can recognize, and then input it to the UART port of the control module, namely the data transceiver terminals TXD3 and RXD3.

[0067] This utility model embodiment achieves a data acquisition design compatible with heterogeneous interfaces through an infrared adapter. It not only supports standard industrial serial ports such as RS232 / RS485, but also can be adapted to infrared adapters in actual use. The control module can obtain raw radiation monitoring data from devices with different interface types, successfully solving the data access problem of special devices that have no physical interface and only optical output, and greatly expanding the versatility and applicability of the device.

[0068] With its multi-interface compatibility (especially infrared adapter), it can be adapted to most mainstream old radiation monitoring equipment on the market, providing users with a unified and standardized upgrade solution that facilitates large-scale, phased deployment and has strong versatility and flexibility.

[0069] In some embodiments, the positioning data transmission device further includes a human-machine interaction module, which includes a display unit connected to the control module via an I2C bus, for displaying radiation monitoring data, current positioning information, and current time information.

[0070] Specifically, the display unit may be an OLED display, an LCD display, or a liquid crystal display, etc. In a preferred embodiment, the display unit uses an OLED display. Figure 7 As shown, the control module is connected to the OLED display via the I2C bus (SDA / SCL pins). The OLED display can show the current device's radiation measurement values, BeiDou positioning status, and latitude and longitude information in real time, facilitating debugging and verification by on-site personnel.

[0071] It should be understood that the positioning data transmission device includes a main body, an OLED display screen disposed on the front of the positioning data transmission device, and other electronic components such as a control module, a positioning module, and a data transmission module disposed inside the main body.

[0072] Furthermore, the human-computer interaction module also includes indicator lights, which are connected to the control module. The control module controls the indicator lights to indicate power status, system operating status, or communication status.

[0073] Specifically, the indicator lights are LEDs. Multiple indicator lights are provided; for example, they may include power indicator lights, system indicator lights, and communication indicator lights. The control module is connected to the indicator lights to control the on / off state of the corresponding indicator lights based on the power status, system operating status, or communication status. Specifically, the power indicator light illuminates when the power is on and turns off when the power is off; the system operating status indicator light illuminates after the control module starts and turns off after the control module stops operating; and the communication status indicator light illuminates when the data transmission module is normally connected to the monitoring terminal and turns off when the connection is lost.

[0074] like Figure 9 As shown in the circuit diagram of the system indicator light, when the control module is started, the system indicator light D1 is enabled to light up.

[0075] This utility model embodiment uses a display unit and indicator lights to intuitively display data and system status information, making it convenient for users to debug and confirm.

[0076] In some embodiments, the positioning data transmission device further includes a power supply and a power monitoring module, such as... Figure 10 As shown, the power monitoring module includes an active switch U2, a first resistor R1, a second resistor R2, a third resistor R3, and a fourth resistor R4. The positive terminal of the power supply is connected to the first terminal of the first resistor R1 and the first connection terminal of the active switch U2. The controlled terminal of the active switch U2 is connected to the second terminal of the first resistor R1 and the monitoring enable terminal of the control module through the second resistor R2. The second connection terminal of the active switch U2 is connected to the monitoring signal input terminal of the control module through the first terminals of the third resistor R3 and the fourth resistor R4. The control module obtains power information through the monitoring signal input terminal. The second terminal of the fourth resistor R4 is grounded.

[0077] Specifically, the power source is a battery or battery pack, which outputs a 5V voltage.

[0078] The active switch U2 can be a MOSFET, a transistor, etc. In one example, the active switch U2 is a MOSFET. The first connection terminal of the active switch U2 is the source of the MOSFET, the second connection terminal of the active switch U2 is the drain of the MOSFET, and the controlled terminal of the active switch U2 is the gate of the MOSFET.

[0079] The monitoring enable terminal BTA_ADC_EN of the control module enables the active switch U2 to conduct, and monitors the voltage signal between the third resistor R3 and the fourth resistor R4 through the monitoring signal input terminal BAT_ADC to obtain the power supply information.

[0080] Furthermore, the positioning data transmission device also includes an alarm circuit, such as... Figure 11 As shown, the alarm circuit includes a buzzer LS1. When the power supply is less than a preset value, the control module controls the buzzer LS1 to sound an alarm.

[0081] This utility model embodiment monitors the power supply through a power monitoring module, which can promptly detect when the power supply is insufficient to replace the battery, thus preventing the battery from running out of power during operation.

[0082] The following describes the workflow of the positioning data transmission device of this utility model embodiment, using the FH40G radiation detector as an example.

[0083] 1. Align the positioning data transmission device with the infrared port of the FH40G radiation detector via an infrared adapter.

[0084] 2. Turn on the positioning data transmission device and the FH40G radiation detector.

[0085] 3. The positioning module begins positioning, and the data transmission module begins registering with the network.

[0086] 4. The FH40G radiation detector performs radiation measurements and transmits the data through the infrared port.

[0087] 5. The infrared adapter receives data and converts it into an electrical signal, which is then sent to the control module of the positioning data transmission device, i.e., the STM32 microcontroller.

[0088] 6. The control module parses the radiation monitoring data and simultaneously obtains the current location information and current time information.

[0089] 7. The control module packages the "radiation monitoring data + current location information + current time information" and displays it on the OLED screen.

[0090] 8. The control module sends data packets to the monitoring end, such as the monitoring center platform, via AT commands through a data transmission device.

[0091] 9. The monitoring terminal can then view the radiation data from this FH40G radiation detector, which includes real-time location and timestamps.

[0092] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and all such modifications and variations fall within the scope of protection.
