DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0031] See also Figure 1 The present invention provides a high-speed rail sound barrier safety monitoring system, which includes a monitoring box 3, a routing box 4 and a monitoring background; the monitoring box 3 includes a box body arranged on the sound barrier, a monitoring unit and a first short-range wireless communication module 3-4 arranged inside the box body; the routing box 4 includes a box body arranged on the sound barrier, a second short-range wireless communication module and a long-range wireless communication module arranged inside the box body;

[0032] The monitoring unit is connected to the first short-range wireless communication module 3-4, which is used to send the safety information of the sound barrier obtained by the monitoring unit to the second short-range wireless communication module via short-range wireless communication. Multiple monitoring boxes 3 are connected to one routing box 4 via short-range wireless communication. The long-range wireless communication module is used to send the safety information of the sound barrier received by the second short-range wireless communication module to the monitoring background. The monitoring background is used to display and store the safety information of the sound barrier sent by the long-range wireless communication module.

[0033] The first short-range wireless communication module 3-4 and the second short-range wireless communication module are short-range wireless communication modules, which are used to implement short-range wireless communication between the monitoring box 3 and the routing box 4. The short-range wireless communication module can be specifically used to implement wireless communication within a range of 100 meters. The long-range wireless communication module can be specifically used to implement wireless communication within a range of more than 100 meters.

[0034] In some specific embodiments, the sound barrier includes columns 1 arranged at intervals and partitions 2 arranged on the columns 1, each of the columns 1 is provided with the monitoring box 3, and a routing box 4 is provided on every several columns 1.

[0035] like Figure 1 and Figure 2 As shown, a monitoring box 3 and a routing box 4 are installed on the upper outer side of the sound barrier column 1. A monitoring box 3 is installed on each sound barrier column 1, and a routing box 4 is arranged every 100 meters. Figure 1 Three monitoring boxes 3 and one routing box 4 are included to illustrate the relationship between system components and do not represent a specific quantity setting. The internal structures of the monitoring boxes 3 and the routing boxes 4 are not drawn here.

[0036] The monitoring box 3 and the routing box 4 are both encapsulated in a sealed metal box body, which is waterproof, dustproof and anti-corrosive. Figure 2 The middle monitoring box 3 is fixed to the sound barrier with four screws. It is located at the top of the sound barrier and installed on the side of the sound barrier facing away from the rails to avoid interference with railway operations. It is installed on each column 1. The routing box 4 is also fixed to the sound barrier with four screws. It is installed on the side of the sound barrier facing away from the rails, below the monitoring box 3.

[0037] In some specific embodiments, reference Figure 3 The monitoring unit includes a signal sensor, a signal processor and a first single-chip microcomputer 3-3. A storage chip 3-1 is also provided inside the box body 3-10 of the monitoring box 3. The first single-chip microcomputer 3-3 is respectively connected to the signal sensor, the signal processor, the storage chip 3-1 and the first short-range wireless communication module 3-4; the first single-chip microcomputer 3-3 performs comprehensive control on each component in the monitoring box 3.

[0038] The signal sensor is used to monitor and obtain the safety signal of the sound barrier; the first single-chip microcomputer 3-3 includes an analog-to-digital converter, and the first single-chip microcomputer 3-3 receives the safety signal through the analog-to-digital converter; the first single-chip microcomputer 3-3 also includes a storage read-write module, which can be specifically a storage read-write circuit. The first single-chip microcomputer 3-3 is used to receive the safety signal and store the safety signal to the storage chip 3-1 through the storage read-write module, and after the signal sensor stops transmitting the safety signal, read and write the safety signal on the storage chip 3-1, and obtain the monitoring result through signal processing by the signal processor; the signal processor obtains the monitoring result of the sound barrier according to the safety signal to form the safety information.

[0039] Specifically, this embodiment proposes integrating a signal processor into the monitoring box 3. After the signal sensor monitors and acquires the safety signal from the sound barrier, the signal processor directly performs in-situ signal processing in the monitoring box 3. Based on the safety signal, the signal processor analyzes whether the sound barrier is faulty or operating properly, generating a monitoring result. The safety information sent by the monitoring box 3 to the routing box 4 can be the monitoring result, thereby avoiding the transmission of a large number of original safety signals, which is beneficial for improving efficiency and reducing power consumption. Accordingly, a memory chip 3-1 is provided in the monitoring box 3 for storing the safety signal of the sound barrier acquired by the signal sensor, so that the original safety signal can be called and sent when needed by the monitoring background.

[0040] The signal processor is a common module in sound barrier monitoring. For example, the signal processor can be set as a comparison circuit to compare the safety signal with the preset signal threshold. If it exceeds the threshold, it is considered that there is a fault. If it is within the threshold range, it is considered to be working normally. The monitoring result is whether there is a fault in the sound barrier or the sound barrier is working normally. The signal processor can also be set as a chip, and the existing fault diagnosis model is set on the chip, so that the specific fault type of the sound barrier can be diagnosed according to the safety signal, and the monitoring result can be the fault diagnosis result.

[0041] Furthermore, the signal processor may be integrated on the first single chip microcomputer 3 - 3 to form an integrated single chip microcomputer with signal processing function. For example, relevant circuits or models of the signal processor may be integrated on the first single chip microcomputer.

[0042] Specifically, the signal sensor is a vibration sensor 3-8, which is installed on the side of the box body 3-10 of the monitoring box 3 connected to the sound barrier, and the axial direction of the vibration sensor 3-8 is arranged to intersect with the side; in other embodiments, the signal sensor can also be other types of sensors, such as strain sensors, etc., for the purpose of obtaining fault diagnosis results based on the obtained safety signal analysis, and the specific type is not limited.

[0043] The first single chip microcomputer 3-3 and the memory chip 3-1 are respectively arranged on a circuit board 3-2. A signal processor can also be arranged on the circuit board 3-2.

[0044] Furthermore, a vibration switch 3-9 is provided inside the box body 3-10 of the monitoring box 3. The vibration switch 3-9 is connected to the first single-chip microcomputer 3-3. The vibration switch 3-9 is used to turn on the first single-chip microcomputer 3-3 when the sound barrier generates a vibration signal. When the vibration signal generated by the sound barrier is greater than a preset threshold, the vibration switch 3-9 will send a signal to the first single-chip microcomputer 3-3. After receiving the signal, the first single-chip microcomputer 3-3 can control other components in the monitoring box 3, such as the signal sensor, the first short-range wireless communication module 3-4, etc. to turn on. That is, when the vibration signal generated by the sound barrier is greater than the preset threshold, the vibration switch 3-9 turns on the first single-chip microcomputer 3-3 so that the first single-chip microcomputer 3-3 controls the monitoring box 3 to start running.

[0045] Furthermore, the first single-chip microcomputer 3-3 is further configured to shut down the monitoring box 3 after the first short-range wireless communication module 3-4 transmits the safety information to the second short-range wireless communication module. That is, after receiving the safety signal transmitted by the signal sensor, storing the safety signal, reading the safety signal and performing fault diagnosis, and transmitting the fault diagnosis result to the routing box 4, the first single-chip microcomputer 3-3 can control other components in the monitoring box 3, such as the signal sensor and the first short-range wireless communication module 3-4, to shut down, placing the monitoring box 3 in a dormant state, thereby reducing power consumption and increasing service life.

[0046] In some specific embodiments, a second single-chip microcomputer is further provided within the body of the routing box 4. The second single-chip microcomputer is connected to the second short-range wireless communication module and the long-range wireless communication module, respectively. The second single-chip microcomputer comprehensively controls the various components in the routing box 4, specifically controlling communication with the monitoring box 3 and with the monitoring backend. The second single-chip microcomputer is configured to transmit the security information received by the second short-range wireless communication module to the monitoring backend via the long-range wireless communication module.

[0047] The second single-chip microcomputer is further configured to send a request message to the first short-range wireless communication module 3-4 via the second short-range wireless communication module. The request message may include status request information for detecting the device status of the monitoring box 3. The second single-chip microcomputer may periodically send status request information to the first single-chip microcomputer 3-3. Upon receiving the status request information periodically sent by the routing box 4, the first single-chip microcomputer 3-3 returns a set of information to the second single-chip microcomputer via the first short-range wireless communication module 3-4. This set of information may be preset information, allowing the second single-chip microcomputer to determine whether the monitoring box 3 is functioning properly.

[0048] The request information may also include data call information. The second single-chip microcomputer is also used to receive the data call information sent by the monitoring background and send the data call information to the monitoring box 3. When the first single-chip microcomputer 3-3 in the monitoring box 3 receives the data call information, it reads the relevant information stored on the storage chip 3-1 and returns the relevant information to the routing box 4 via the first short-range wireless communication module 3-4. The second single-chip microcomputer in the routing box 4 sends the relevant information to the monitoring background via the long-range wireless communication module for retrieval.

[0049] In some specific embodiments, the first short-range wireless communication module 3-4 and the second short-range wireless communication module respectively include a Lora communication circuit and a short-range communication antenna 3-12, the Lora communication circuit is arranged inside the corresponding box body, and the short-range communication antenna 3-12 is arranged outside the corresponding box body, and the Lora communication circuit and the short-range communication antenna 3-12 are connected;

[0050] The remote wireless communication module includes a 4G or 5G wireless network communication circuit and a remote communication antenna. The 4G or 5G wireless network communication circuit is arranged inside the box body of the routing box 4, and the remote communication antenna is arranged outside the box body of the routing box 4. The 4G or 5G wireless network communication circuit and the remote communication antenna are connected;

[0051] The short-range communication antenna 3-12 and the long-range communication antenna are respectively arranged under the corresponding box body.

[0052] Figure 1 The arrows in the figure indicate the direction of data transmission. In this example, the monitoring box 3 and the routing box 4 transmit information via LoRa wireless communication. The routing box 4 transmits information to the cloud storage center and the monitoring center via 4G or 5G wireless network communication. The cloud storage center and the monitoring center can exchange data via a wireless network such as a 4G or 5G wireless network. In actual applications, other types of communication methods can also be used.

[0053] Furthermore, the monitoring box 3 and routing box 4 are each equipped with a self-powered system that powers the components within the corresponding box. The monitoring box 3 is a small, self-powered, and long-term autonomous intelligent monitoring unit that can monitor the vibration signals of the sound barrier when a high-speed train passes through, analyze the vibration signals in real time, and perform fault diagnosis on the sound barrier. The routing box 4 is a small, self-powered, and long-term autonomous intelligent communication unit. The self-powered systems of the monitoring box 3 and routing box 4 can be powered by solar energy, but other self-powered methods can also be used depending on the actual environmental conditions.

[0054] Specifically, the self-powered system is a solar power system, which includes a solar panel 3-11, a charge-discharge controller 3-5, and a lithium battery pack 3-7. The solar panel 3-11 is arranged on the outside of the corresponding box body, and the charge-discharge controller 3-5 and the lithium battery pack 3-7 are arranged on the inside of the corresponding box body. The charge-discharge controller 3-5 is connected to the solar panel 3-11 via a waterproof connector 3-6, and the charge-discharge controller 3-5 is connected to the lithium battery pack 3-7. This specific embodiment uses a solar power system to power the monitoring box 3 and the routing box 4. In actual applications, different self-powered modes can be selected according to the on-site environment, and are not limited to solar power supply.

[0055] Figure 3 The memory chip 3-1 and the single chip microcomputer are located on the circuit board 3-2. The circuit board 3-2 is connected to the first short-range wireless communication module 3-4, the vibration sensor 3-8, the self-power supply system, etc. for control. In order to simplify the schematic diagram and highlight the characteristics of the utility model, other specific circuit elements are not marked. The bottom of the first short-range wireless communication module 3-4 is connected to the antenna outside the box body 3-10 of the monitoring box 3, such as Figure 4 shown.

[0056] Figure 3 The circuit components related to the self-powered system are the charge and discharge controller 3-5, one end of which is connected to the external power generation part, namely the solar panel 3-11, through a waterproof connector 3-6, and the other end is connected to the vibration sensor 3-8, the circuit board 3-2 and the vibration switch 3-9 through other lines. It is responsible for providing electrical energy. The circuit board 3-2 can be connected to the first short-range wireless communication module 3-4 to power it and establish a communication connection. Figure 3 The system also includes a lithium battery pack 3-7, which is part of the self-powered system and is connected to the charge and discharge controller 3-5. It is responsible for storing excess electrical energy and maintaining the operation of the monitoring box 3 when the self-power supply is insufficient. In this example, after power consumption estimation and redundant design, the rated voltage of the lithium battery pack 3-7 is approximately 3.7V and the capacity is approximately 300 mAh.

[0057] Figure 3The monitoring box 3 also includes a vibration sensor 3-8, the axis of the probe of which intersects with the inner surface of the monitoring box 3, and the inner surface of the monitoring box 3 is tightly fixed to the steel frame of the sound barrier. Optionally, the axial direction of the vibration sensor 3-8 forms a 45-degree angle with the side of the box body 3-10 connected to the sound barrier, which can realize vibration monitoring of the sound barrier along the partition and perpendicular to the partition; specifically, a mounting seat with an inclined surface can be provided on the side of the box body 3-10 connected to the sound barrier, and the vibration sensor 3-8 can be connected to the surface of the mounting seat by screws, etc., so that the axial direction of the vibration sensor 3-8 intersects with the inner surface of the box body 3-10. The vibration sensor 3-8 accurately receives the vibration signal, and the signal generated by the vibration sensor 3-8 is directly transmitted to the core circuit board for processing.

[0058] Figure 4 The external structure of the monitoring box 3 in this embodiment is described. A solar panel 3-11 is mounted on top of the box body 3-10 of the monitoring box 3 to maximize solar energy absorption. The solar panel is connected to the interior of the monitoring box 3 via a waterproof connector 3-6, specifically a conductive connection, to power the monitoring box 3. Figure 4 The housing 3-10 of the monitoring box 3 is, in this example, made of aluminum alloy with an anti-corrosion coating. The housing is secured with stainless steel screws, and rubber rings are used at the connection between the housing cover and the screws to provide waterproofing. The housing used in this embodiment is only one design approach; in actual applications, different solutions may be selected based on the site environment. Figure 4 The middle rod-shaped communication antenna is the short-range communication antenna 3-12. The short-range wireless communication module sends and receives information through this communication antenna. In this example, the communication antenna is placed at the lower part of the box body 3-10 of the monitoring box 3 to reduce the impact of factors such as rain and light on it. The connection between the communication antenna and the inside of the shell is equipped with a waterproof connector 3-6.

[0059] The configuration of the short-range communication module, long-range communication module and self-power supply system of the routing box 4 is similar to that of the monitoring box 3 and will not be described in detail.

[0060] In some specific embodiments, the monitoring backend includes a cloud storage unit 5 and a monitoring unit 6. The cloud storage unit 5 is used to store the security information sent by the remote wireless communication module, and the monitoring unit 6 is used to receive the security information. The cloud storage unit 5 is a storage module, and the monitoring unit 6 is a human-computer interaction module.

[0061] Specifically, when the safety information is fault information, that is, when a fault is diagnosed, the monitoring box 3 can send the safety information to the routing box 4, and the routing box 4 can send the safety information directly to the monitoring unit 6 for alarm, and the safety information can be synchronously sent to the cloud storage unit 5 for storage; when the safety information is no fault information, the monitoring box 3 can choose not to send it to the routing box 4, or after sending it to the routing box 4, the routing box 4 can directly send the safety information to the cloud storage unit for storage.

[0062] The monitoring unit 6 is also used to send data call information to the routing box 4. After the second single-chip microcomputer in the routing box 4 receives the data call information, it will send it to the monitoring box 3. After the first single-chip microcomputer 3-3 in the monitoring box 3 receives the data call information, it will return the relevant call information to the monitoring unit 6 through the routing box 4, and can also be synchronously returned to the cloud storage unit for storage.

[0063] The cloud storage unit 5 and monitoring unit 6 can be developed according to the actual needs of the user, or can be implemented by adding interfaces based on the user's existing railway monitoring and operating system. That is, the cloud storage unit 5 and monitoring unit 6 can be integrated on the host computer.

[0064] The workflow of the high-speed rail sound barrier safety monitoring system provided in this embodiment is as follows:

[0065] The monitoring box 3 receives vibration signals when a train passes by, performs data analysis and fault diagnosis, and actively sends an alarm message to the routing box 4 if a fault is found.

[0066] The routing box 4 regularly performs communication checks and feature data acquisition with the monitoring box 3. The communication between the routing box 4 and the monitoring box 3 is achieved through short-range communication. The routing box 4 then transmits the data to the monitoring unit 6 and the cloud storage unit 5 through long-range communication.

[0067] Figure 5 It shows the specific monitoring process of this instance:

[0068] Serial number a represents the standby state of the monitoring box 3 when it is not awakened by the vibration generated by the passing train or receives a request from the routing box 4.

[0069] Sequence number b indicates that the monitoring box 3 detects vibration, enters the working state, and starts receiving data.

[0070] Sequence number c indicates that the monitoring box 3 starts to measure the vibration signal, and the first single chip microcomputer 3 - 3 receives the vibration data and stores it in the storage chip 3 - 1 .

[0071] Serial number d indicates that when the vibration signal is weak enough, the single chip microcomputer determines that the reception is finished, and then reads the data from the memory chip 3-1, analyzes and processes it, and determines whether a fault occurs.

[0072] Sequence number e indicates that when no fault is detected, the monitoring box 3 returns to the standby state.

[0073] Serial number f indicates that when a fault is detected, the single chip microcomputer sends a fault alarm and related information to the routing box 4 through the Lora communication circuit.

[0074] Serial number g indicates that the routing box 4 in the system regularly wakes up the monitoring box 3 through the Lora communication circuit when the monitoring box 3 is on standby, obtains the equipment working status information and / or calls data-related information. In this example, the routing box 4 sends a request to the monitoring box 3 every night, and the monitoring box 3 sends a set of processed data to the routing box 4 for judging whether the monitoring box 3 is working normally. In actual applications, in addition to the information sent in this example, the content sent can also be customized according to user needs.

[0075] Sequence number h indicates that after receiving the data, routing box 4 sends the corresponding information to cloud storage unit 5 and monitoring unit 6 via the 5G mobile network. In this example, routing box 4 sends the information obtained from monitoring box 3 to the cloud storage center, namely the cloud storage unit, and the fault alarm information is directly sent to the monitoring center, namely monitoring unit 6. The monitoring center can further understand the situation by retrieving data from the cloud storage center. In this example, 5G mobile network is used for transmission between routing box 4 and the monitoring background, and between the cloud storage unit and monitoring unit 6. In actual situations, different remote communication methods can be used according to transmission requirements.

[0076] Sequence number i indicates that after the routing box 4 completes receiving the data from the monitoring box 3 and sending it to the cloud storage center and the monitoring center, it instructs the monitoring box 3 to re-enter the standby state.

[0077] This new system has a long lifespan, low cost, and efficient workflow, ensuring safe high-speed rail operations.
