BRIEF DESCRIPTION OF DRAWINGS
[0021] In order to more intuitively illustrate the prior art and the present application, exemplary drawings are given below. It should be understood that the specific shapes, configurations shown in the drawings should not be considered as limiting conditions in the implementation of the present application; for example, based on the technical concepts disclosed in the present application and the exemplary drawings, those skilled in the art can easily make routine adjustments or further optimizations to the increase / decrease / assignment of certain units (components), specific shapes, positional relationships, connection methods, size ratio relationships, etc.
[0022] Figure 1 A structural schematic diagram of a wireless sound and light warning device provided by an illustrative embodiment of the present application is shown. DETAILED DESCRIPTION
[0023] In order to make the purpose, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the drawings.
[0024] First, the implementation scenario is introduced. As mentioned in the background art, the main reason for the aging and action delay problems of the relay in long-term use is that the internal mechanical components and electrical contacts will be affected by wear, corrosion, fatigue, etc. during repeated work. These problems will cause the response time of the relay to become longer and the working precision to decrease, thereby affecting the stability and reliability of the entire control system.
[0025] For train on-board systems, these problems of the relay are particularly prominent, especially after long-term use, the aging problem will gradually affect the safety and performance of the train. Therefore, the traditional relay system is often replaced by a modern logic control system. The logic control system does not rely on mechanical components and controls in an electronic manner, so it has higher stability and accuracy.
[0026] However, when a new logic control system is added to the train, the problem of access difficulty is usually encountered, especially it is difficult to directly connect with the train backbone network, and the distribution cabinet wiring is complex. At this time, the monitoring problem of the logic control system becomes a big problem. Therefore, developing a device like the wireless sound and light warning device proposed in the present application can realize fault monitoring without relying on traditional wiring, providing a simple and flexible solution for later equipment installation. The wireless sound and light warning device will be described below through various embodiments.
[0027] Embodiment 1
[0028] Reference is made to Figure 1 which shows a structural schematic diagram of a wireless sound and light warning device provided by an illustrative embodiment of the present application.
[0029] The wireless sound and light warning device is suitable for a train-mounted logic control system, and comprises a warning board card and a wireless sound and light warning box installed in the train-mounted logic control system.
[0030] The warning board card is connected to the train-mounted logic control system through wired or wireless communication, and the wireless sound and light warning box is connected to the warning board card through wireless communication.
[0031] The warning board card is used to detect the fault state of the train-mounted logic control system and send the analyzed fault data to the wireless sound and light warning box.
[0032] In an example, in the daily operation of a subway train, the train-mounted logic control system may fail, and the traditional method requires complex wiring and access to the train backbone network, which brings difficulties to later maintenance. The wireless sound and light warning device in the present application connects the warning board card to the train-mounted logic control system through wired or wireless communication, and realizes real-time monitoring of the train operation state without complex wiring. When the train-mounted logic control system fails, the warning board card analyzes the fault state data and sends the data to the wireless sound and light warning box through the wireless communication module, and the latter sends out light signals and sound signals to prompt the staff to handle the fault in time.
[0033] In an example, when a new logic control device is installed in a train system, if there is no original train-mounted network interface, the traditional method needs to make major changes to the train network, while the present application solves this problem through wireless communication. The flexible installation of the wireless sound and light warning box and the wireless data transmission can adapt to different types of trains, especially those without reserved network interfaces. After the device is installed, the warning board card can still effectively monitor the system operation state and alarm through the warning box to ensure the safe operation of the train.
[0034] In an example, the wireless sound and light warning device of the present application can also be used in cooperation with other monitoring systems to realize remote monitoring of the train-mounted logic control system. The application of the wireless communication module enables the system to remotely transmit fault data, which facilitates the timely diagnosis and response of the fault by the operation center or maintenance personnel, reduces the time and cost of on-site handling, and improves the safety and reliability of the train.
[0035] The embodiments of the present application solve the problems of difficult fault monitoring and difficult access in the traditional train-mounted logic control system by adopting wired or wireless connection between the wireless sound and light warning device and the train-mounted logic control system. Specifically, the warning board card is connected with the train-mounted logic control system through wired or wireless communication, so that the system can detect the fault state of the train-mounted logic control system in real time, and transmit the parsed fault data to the wireless sound and light warning box. The wireless sound and light warning box is connected with the warning board card through wireless communication, effectively reducing the complexity of traditional wiring, and is especially suitable for the case of late equipment installation or difficult direct access to the train backbone network. The scheme provides a low-cost and low-maintenance solution, which has a significant advantage especially in the environment with large network changes and difficult line arrangement.
[0036] Embodiment 2
[0037] Optionally, the communication interface includes a backplane CAN, Ethernet, MVB and hard-wire interface.
[0038] Since the train-mounted logic control system may have different communication protocols and network structures, these interfaces can cover different network requirements such as CAN, MVB and Ethernet, ensuring that the warning board card can be seamlessly connected with the existing control system. By using backplane CAN, Ethernet and MVB interfaces, the stability and high speed of data transmission are ensured, the state information of the train-mounted control system can be obtained in time, and the timeliness of fault alarm is ensured. In the future, when the train-mounted control system is upgraded or replaced, the warning board card can be quickly adapted and deployed through these different interfaces, reducing the complexity and additional cost caused by equipment upgrade.
[0039] In one example, in a train, the train-mounted logic control system is connected with the warning board card through interfaces such as CAN bus, Ethernet or MVB. For example, during the train operation, if the train-mounted control system detects a fault of a certain device through the MVB interface, the warning board card will receive the fault information through the interface. After parsing the fault information, the warning board card transmits the data to the wireless sound and light warning box through the wireless communication module for alarm. This connection method based on multiple protocol interfaces ensures the comprehensiveness and real-time of data acquisition.
[0040] In one example, assuming that the train-mounted logic control system needs to add new functions or devices, such as adding a new fault alarm module, the traditional method may need to rewire or change the train-mounted network structure, but by using multiple communication interfaces, the warning board card can be easily connected with the existing train system. For example, if the new device is connected to the train-mounted logic control system through the Ethernet interface, the warning board card can access and monitor the fault state through the Ethernet interface, simplifying the process of installation and upgrade.
[0041] In one example, since different train models can employ different communication protocols and network architectures, using backplane CAN, MVB, Ethernet and hard-wired interfaces can ensure that the warning board card can be compatible with multiple train configurations. For example, older trains can employ CAN bus for data transmission, while new trains can use Ethernet interface. The warning board card, by adapting these interfaces, can achieve unified monitoring functions on different types of trains, without the need to redesign the control system, reducing the cost of transformation.
[0042] In one example, when the train fails, the warning board card collects fault data through different interfaces and sends it to the maintenance personnel. Assuming that a train has a power system failure, the warning board card is connected to the on-board control system through the hard-wired interface, detects the abnormality of the power system in real time, and transmits the fault data to the wireless sound and light warning box through the wireless communication module for alarm, while sending the fault data to the remote maintenance platform through the Ethernet interface, facilitating the maintenance personnel to diagnose and handle the fault remotely.
[0043] The communication interfaces used in the embodiments of the present application include backplane CAN, Ethernet, MVB and hard-wired interface, providing the warning board card with multiple data transmission methods. These interfaces can be flexibly adapted to different types of train on-board logic control systems, enhancing the compatibility and expandability of the system. Specifically, backplane CAN, Ethernet, MVB and hard-wired interface can support data exchange between different devices, so that the warning board card can collect the fault status of the train on-board logic control system in real time through these interfaces.
[0044] Embodiment 3
[0045] Optionally, the warning board card is integrated with an acquisition circuit, a power supply circuit, a controller and a first radio frequency module, and the wireless sound and light warning box is integrated with a second radio frequency module; the acquisition circuit is connected with the train on-board logic control system through at least one of the backplane CAN, the Ethernet, the MVB and the hard-wired interface; the controller is used to receive the acquisition signal of the acquisition circuit for fault state analysis, and send the analyzed fault data to the sound and light alarm through the first radio frequency module, and the second radio frequency module is used to receive the fault data; the first radio frequency module and the second radio frequency module are connected by wireless communication.
[0046] In one example, assuming that a device failure occurs during train operation, the warning board card is connected to the on-board logic control system through its acquisition circuit (such as through the MVB interface) to obtain fault data. After the acquired signals are parsed by the controller, the fault data is transmitted to the wireless sound and light warning box through the first radio frequency module. After receiving the fault data, the wireless sound and light warning box sends an alarm signal through the buzzer and indicator light, prompting the train staff to take appropriate maintenance measures. Wireless communication ensures that fault information can be transmitted in real time, avoiding the delay and complexity of traditional wiring methods.
[0047] In one example, during the late installation of the train, the traditional method may need to connect the device through the train backbone network or wiring, while the present application realizes the rapid access of the device through the wireless radio frequency module. Assuming that a train adds a set of monitoring system, the warning board card is connected with the on-board system through the Ethernet interface, real-time monitoring of fault status, and sending data to the wireless sound and light warning box through wireless communication. This wireless communication method not only saves the wiring cost, but also facilitates the later maintenance, ensuring the flexibility and scalability of device installation.
[0048] In one example, in the remote fault monitoring system, the controller of the warning board card can not only alarm locally when the train fails, but also transmit fault information to the remote monitoring platform through the wireless communication module. For example, when the train power system fails, the warning board card is connected with the on-board control system through the hard-wire interface, and after collecting the fault signal of the power system, the controller will transmit the fault information to the wireless sound and light warning box through the radio frequency module and perform local alarm. At the same time, the fault information can also be transmitted to the remote monitoring system through the network, facilitating remote diagnosis and processing by maintenance personnel. This greatly improves the response speed and efficiency of train fault handling.
[0049] In one example, different trains may use different communication protocols or interface types, and the warning board card integrates multiple communication interfaces (such as CAN, Ethernet, MVB and hard-wire interface) to ensure that whether it is an old train or a modern train, the system can adapt flexibly and perform fault monitoring and alarm. In a train upgrade, the warning board card can seamlessly interface with the existing control system and transmit fault data wirelessly, improving the stability and safety of the train system.
[0050] In the embodiments of the present application, the warning board card receives fault signals from the train-mounted logic control system through the acquisition circuit. The controller analyzes these acquisition signals, judges the fault state, and sends the analyzed fault data to the second radio frequency module of the wireless sound and light warning box through the first radio frequency module. In this way, the fault information can be transmitted in real time, and the sound and light warning box can trigger the sound and light alarm to prompt the staff to handle the fault in a timely manner. Using the radio frequency module (i.e., wireless communication method) instead of traditional wired connection reduces the wiring complexity and maintenance cost of the system. Wireless transmission eliminates the need for direct access to the train backbone network or complex wiring between devices, especially for late-stage device installation or difficult wired connection scenarios. The warning board card integrates multiple communication interfaces (such as backplane CAN, Ethernet, MVB, and hard-wired interfaces), which can adapt to the needs of different train-mounted logic control systems. Through these interfaces, the warning board card can collect various fault information in real time and transmit it to the wireless sound and light warning box, providing unified monitoring and alarm functions for different types of trains. The first and second radio frequency modules transmit data through wireless communication, ensuring fast, efficient, and stable data transmission. This wireless communication method has low latency and high reliability, which helps to respond to system failures in a timely manner and ensures the safe operation of the train.
[0051] Embodiment 4
[0052] Optionally, the warning board card also integrates a power supply circuit for power supply, which provides DC 24V power supply when connected to the train-mounted logic control system.
[0053] In one example, in a train-mounted system, if a wireless sound and light warning device needs to be added, external power supply access may be required traditionally, but the present application avoids installing external power supply for the device by integrating a power supply circuit. Assuming that a wireless sound and light warning device needs to be added to the train, during installation, the warning board card directly obtains power from the vehicle-mounted power system, such as DC 24V, without the need for additional wiring or battery system, simplifying the complexity of device installation and later maintenance.
[0054] In one example, assuming that the train has a power system failure, the warning board card obtains stable power supply through the power supply circuit and continues to work. The fault signals collected by the acquisition circuit are transmitted to the controller, and the analyzed data are sent to the wireless sound and light warning box through the wireless radio frequency module for alarm. In this case, the power supply circuit can ensure that the warning board card can work normally when a fault occurs, and send an alarm signal to the staff in a timely manner, ensuring the safe operation of the train.
[0055] In one example, when the train is in long-time operation, the integrated power supply circuit can effectively adjust the power consumption to avoid power waste caused by long-time operation of the device. For example, the warning board card runs in a low-power mode when there is no fault, and activates a higher-power alarm mode when a fault occurs, thereby optimizing energy efficiency and reducing energy consumption, which helps the overall energy management of the train.
[0056] In one example, if the train has an emergency failure, the power supply circuit of the warning board card can ensure that the device continues to work in an emergency state without worrying about the interference or power failure of the external power supply. This integrated power supply solution improves the stability of the system and avoids potential safety hazards caused by external power supply failure.
[0057] In the embodiments of the present application, the power supply circuit can provide stable voltage and current according to the working requirements of the device, avoid device failure caused by power fluctuations or instability, ensure the continuous operation of the warning board card and related modules (such as controllers, radio frequency modules), and improve the reliability of the device. The integrated power supply circuit means that there is no need to provide an external power supply or a battery for the warning board card, which simplifies the installation process, especially when the train device is installed, avoiding additional power supply wiring and access work, reducing the installation and maintenance cost of the system. By integrating the power supply circuit into the warning board card, the need for external power supply equipment is reduced, the design of the entire system is optimized, the compactness and integration of the device are improved, and the limited space requirement of the train is met. The integrated power supply circuit can automatically adjust the power supply according to the load, optimize energy efficiency, and reduce unnecessary energy consumption, thereby reducing energy consumption while ensuring stable operation of the system, meeting the energy-saving and environmental protection requirements.
[0058] Embodiment 5
[0059] Optionally, the wireless sound and light warning box is provided with a DC 110V interface, which is connected to the vehicle power supply interface and supplies power to the wireless sound and light warning box.
[0060] In one example, if a fault occurs during train operation, the warning board card will analyze the fault data through its controller and transmit the data to the wireless sound and light warning box through the radio frequency module. After receiving the data, the wireless sound and light warning box immediately sends a sound and light alarm to the staff. The wireless sound and light warning box obtains power from the train power system through the DC 110V interface to ensure the continuous operation of the warning device and is not affected by external power failure or insufficient battery power.
[0061] In one example, when the train needs to add a wireless sound and light warning device, the warning box can be directly connected to the original power system of the train through the DC 110V interface to obtain DC 110V power supply, without the need for additional installation of independent power supply or battery for the device, simplifying the installation process of the device and ensuring the long-term stable operation of the device, reducing the complexity of later maintenance.
[0062] In one example, when the train power system is modified or upgraded, the new wireless sound and light warning box can be connected to the existing power supply system of the train through the first and DC 110V interfaces. This design is compatible with the original power equipment and interface when the system is upgraded, avoiding large-scale modification of the power system and reducing the upgrade cost and time cost.
[0063] In one example, when the train power system fails, the power supply of the train on-board logic control system and the wireless sound and light warning box can still be guaranteed. Even if other devices fail, the DC 110V interface can still obtain stable power supply from the main power system of the train, ensuring that the wireless sound and light warning device can continue to alarm and prompt in case of failure, and ensuring the safe operation of the train.
[0064] As shown in Figure 1 For clarity of reference, the train on-board power supply system is marked with a first DC 110V interface, and the interface of the wireless sound and light warning box is marked as a second DC 110V interface. The wireless sound and light warning box can be directly powered from this system or other interfaces, which is not limited. Thus, in the embodiments of the present application, through the connection of the first DC 110V interface and the second DC 110V interface, the wireless sound and light warning box can directly obtain stable DC 110V power supply from the train on-board power supply, ensuring that the device can work continuously during the train operation, avoiding the dependence on external power supply, and improving the reliability and stability of the system. By using the train on-board power supply system to power the wireless sound and light warning box, the need for separate installation of batteries or external power lines for the wireless sound and light warning box is avoided, simplifying the power wiring design of the device and reducing the installation and maintenance cost of the device. This design effectively utilizes the original power system of the train for device power supply, without the need for additional power configuration or modification, reducing the modification of the train power system and reducing the cost and complexity of the entire system. Through the DC 110V interface connection, the system ensures that the wireless sound and light warning box uses voltage and current that match the train power system, avoiding power safety problems caused by unstable or mismatched voltage, and ensuring the energy saving and safety of the device.
[0065] Embodiment 6
[0066] Optionally, the wireless sound and light warning box is equipped with an indicator light, which displays the received fault data and emits a warning in the form of sound; the wireless sound and light warning box is equipped with a buzzer, which emits a warning in the form of light; the wireless sound and light warning box is equipped with an interrupt switch, which controls the sound and light alarm state.
[0067] In one example, during the operation of the train, assuming that a device failure occurs, the warning board card transmits the data to the wireless sound and light warning box after the controller analyzes the fault signal. The wireless sound and light warning box emits a loud alarm sound through the buzzer and a flashing light signal through the indicator light, ensuring that the staff can promptly detect the failure in any environment. This dual warning method is particularly effective in noisy environments.
[0068] In one example, during routine maintenance or operation, the staff can control the alarm state through the interrupt switch as needed. For example, when the train is running normally and there is no failure, the sound and light alarm can be stopped by turning off the interrupt switch to reduce unnecessary noise and interference; when a failure occurs, the buzzer and indicator light will immediately work to remind the staff to check and repair in time.
[0069] In one example, when the train has an emergency failure, the high-frequency sound emitted by the buzzer and the flashing of the indicator light can quickly attract the attention of the staff, ensuring a quick response. This fast feedback mechanism is crucial for the safety of the train, especially in high-risk situations, which can minimize accidents caused by slow response to failures.
[0070] In one example, in some special situations, such as when the train is out of service or being repaired, the staff can manually stop the operation of the warning device through the interrupt switch. This flexible alarm control method makes the device more applicable in different use scenarios, avoiding false alarms and interference in the absence of failures or non-emergency situations.
[0071] In one example, the indicator light and buzzer of the wireless sound and light warning box can be used in conjunction with other monitoring systems. For example, in a remote monitoring system, when a device fails, the wireless sound and light warning box provides immediate feedback through the local indicator light and buzzer, while the remote monitoring platform also receives alarm information to take timely follow-up actions.
[0072] In the embodiments of the present application, the wireless sound and light warning box combines the two alarm forms of indicator light and buzzer. The indicator light conveys failure information to the staff through bright light or flashing, while the buzzer further enhances the warning effect by emitting sound, ensuring that attention can be effectively drawn in different environments (such as noisy environments). The response of the indicator light and the buzzer is based on real-time processing of the received failure data. When a train failure occurs, the wireless sound and light warning box can quickly and accurately display the failure status, ensuring that the staff can discover the problem in time and take measures. The wireless sound and light warning box is equipped with an interrupt switch, allowing the device to turn on or off the sound and light alarm state as needed. This flexibility can be adjusted according to the actual scene, for example, turning off the alarm when it is not needed to avoid unnecessary noise interference. Through the dual alarm of the buzzer and the indicator light, the wireless sound and light warning box can provide effective warning in any situation, especially when a train failure occurs, it can quickly and clearly inform the staff, improving the safety and emergency handling capability of the system.
[0073] The above is only an optional embodiment of the present application and does not limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
