Description

Technical Field

[0001] The utility model relates to the field of data sampling, in particular to a modular situation awareness device. Background Art

[0002] As an intelligent device that can monitor, analyze and predict the environment or system status in real time, situational awareness devices can achieve comprehensive understanding of complex environments through multi-source data fusion and intelligent algorithms. They provide support for decision makers in many fields such as military, security, industry, transportation and smart cities, helping them to quickly respond to potential threats or abnormal situations, and play an important role in various industries.

[0003] However, in actual applications, the amount of data collected and the input signals required by situational awareness devices vary significantly across different systems. Designing a unified situational awareness device to meet the needs of all systems would waste a lot of resources and significantly increase the cost of the entire system.

[0004] Take the relevant technology applications in the power industry as an example, Figure 1 and Figure 2 As shown, Figure 1 This is a schematic diagram of a conventional dual power conversion system with step-by-step switching. Figure 2 This is a schematic diagram of a conventional two-incoming, one-busbar dual power conversion system. In the standard configuration, data collection points with step-by-step switching functionality require additional data collection from the S1 and S2 load circuit breakers, compared to conventional two-incoming, one-busbar power conversion systems. These data include busbar temperature, closing and opening coil operating status, and energy storage motor operating status. This brings the total number of digital quantities required to be measured to 2 × 2n (where n is the number of load levels). Integrating these additional signals into a centralized status control unit for processing dramatically increases the number of interfaces directly connected to the unit. Handling all of these signals by the unit would result in significant resource waste. Furthermore, in actual engineering applications, there are specialized systems with four, five, or even more specific load levels. For these multi-load level scenarios, using a centralized status control unit to collect the relevant signals would not only hinder processor processing speeds, but also create excessive wiring requirements, making the unit unsuitable for field applications. Furthermore, this would result in a large size for the status control unit, limiting its installation options.

[0005] Furthermore, these situational status devices are often used in specialized, custom applications that place high demands on the overall system. Applications vary significantly from project to project, and even equipment of the same level may require different wiring methods depending on their requirements. Due to the varying number and configuration of incoming wires, it's impossible to design a universal situational status device that works for all specialized applications. Utility Model Content

[0036] Reference Attachment Figure 3 To the attached Figure 8 As shown in FIG, a modular situation awareness device 100 of the present invention is shown. Figure 3, which is a block diagram of the modular situational awareness device 100. The modular situational awareness device 100 includes a data integration module 200, at least one digital quantity acquisition module 300, at least one data bus 400, and at least one network bus 500. The digital quantity acquisition module 300 is communicatively connected to the data integration module 200 via the data bus 400 and the network bus 500. The digital quantity acquisition module 300 is configured to acquire digital quantity status and send it to the data integration module 200, while receiving and parsing control commands issued by the data integration module 200 and driving its own first sensor 600 to perform data acquisition operations. The data integration module 200 is configured to receive requests from external devices and respond to them, collect digital quantity signals transmitted by the digital quantity acquisition module 300, and acquire data according to the current execution process, and send acquisition commands to the digital quantity acquisition module 300 to perform data acquisition and integration operations of different protocols.

[0037] For details, refer to the attached Figure 4 As shown, in one embodiment of the present invention, the data bus 400 can be implemented as including at least one 485 bus, at least one CAN bus, and one 232 bus in this embodiment. The data integration module 200 can be installed separately or in one of the circuit breaker electrical cabinets. Since the data integration module 200 and the digital quantity acquisition module 300 adopt a stacked design, the data integration module 200 is a stack of boards of the same size, so the volume of the data integration module 200 can be greatly reduced, which is very convenient for installation in the cabinet. The data integration module 200 and the digital quantity acquisition module 300 are internally connected, so no wiring is required. The digital quantity acquisition module 300 receives and parses the control commands issued by the data integration module 200 and drives the first sensor 600, the second sensor 601, the third sensor 602, and the fourth sensor 603 to perform data acquisition operations.

[0038] Reference Attachment Figure 5 FIG2 is a schematic diagram of the digital quantity acquisition module 300 of the modular situational awareness device 100. In this embodiment, the digital quantity acquisition module 300 functions as a telemetry module, and each digital quantity acquisition module 300 has a unique module address. For example, the digital quantity acquisition module 300 may utilize an STM32F103 or similar microprocessor, with at least 64KB of RAM and 512KB of FLASH memory. Furthermore, it may include a CAN data bus, a 232 data bus, and a 485 data bus for real-time communication with the data integration module 200, transmitting various current telemetry data.

[0039] Reference Attachment Figure 6 Figure 2 shows a schematic diagram of the data integration module 200 of the modular situational awareness device 100. In this embodiment, the data integration module 200 is the specific conversion logic operating body. An internal embedded processor runs the conversion program and can flexibly adjust program files based on changing customer needs to accommodate different project requirements. For example, the data integration module 200 may utilize an STM32F407 or similar microprocessor; have at least 512KB of RAM, 2MB of FLASH memory, an 8GB SD card, at least one RJ45 Ethernet interface, two isolated RS485 buses, and two isolated RS232 buses for user use.

[0040] Reference Attachment Figure 7 Figure 2 shows a schematic diagram of the communication unit PCB within the digital acquisition module 300. The communication unit has a transmission range of at least 200 meters. The communication unit's CAN bus and 485 bus signals are converted into USART serial data for easier processing by a microprocessor. Upon receiving this control signal, the CPU within the digital acquisition module 300 immediately drives the sensor to perform the corresponding action, thereby controlling the downstream sensor.

[0041] Reference Attachment Figure 8 The figure shows a schematic diagram of the sampling circuit in the digital quantity acquisition module 300. The main function of the sampling circuit is to perform optical isolation on the input of the sampling state and then send it back to the CPU for acquisition. Pin 1 of the optocoupler input side is connected to the external signal input side through the current limiting resistor R94 and the pull-up resistor R96, and pin 3 is grounded. C56 is used for filtering and D48 is a TVS diode used to protect the circuit from damage by high voltage transients. Pin 4 of the optocoupler output side is grounded, and pin 6 is connected to the low-voltage side working power supply VCC3.3V through the protection diode D47 and the pull-up resistor R95. C55 is also a filter capacitor, and the filtered signal at pin 6 is directly sent to the CPU. In this circuit, when the optocoupler input DI_IN_22 signal is low level 0, the light-emitting diode on the primary side of the optocoupler does not work, so the transistor on the output side of the optocoupler is also not turned on. At this time, the GPIO_IN_22 signal on pin 6 is high level 1; when the DI_IN_22 signal is high level 1, the light-emitting diode of the optocoupler starts to work, and the secondary side transistor of the optocoupler is turned on. At this time, the GPIO_IN_22 signal on pin 6 is low level 0.

[0042] The modular situation awareness device 100 is further described in detail below in conjunction with the specific usage process. All the digital quantity acquisition modules 300 that are switched on and off step by step are connected to the CAN bus via the 485 bus and form a whole with the data integration module 200. The difference between the multiple digital quantity acquisition modules 300 is distinguished by the device address and is determined according to the load priority level. All signal samples of the multiple digital quantity acquisition modules 300 are polled by the data integration module 200 in an orderly manner through the address to obtain the required digital quantities, thereby ensuring that the signals of each sensor collected by all the digital quantity acquisition modules 300 are received by the data integration module 200 in an orderly manner. The data collected by the digital quantity acquisition module 300 is updated every 50 milliseconds, and the latest collected 50 milliseconds of data replaces the first cached 50 milliseconds of data, and the results are stored in the cache area of ​​the specified address and wait for the query of the data integration module. The digital quantity acquisition module 300 uses the sampling status and sampling data provided by the device address as the basis for real-time device situation.

[0043] During the operation of the system, the main control module sends telemetry commands according to the priority level through the communication bus to poll the sampling status of all the digital quantity acquisition modules 300. After receiving the query command that matches its address, the digital quantity acquisition module 300 replies with the corresponding sampling status and sampling data. In this way, the data integration module 200 can continuously query the calculation and sampling results of all front-end sampling execution modules at a certain time interval, thereby obtaining the power quality status of all incoming lines and the health information of switches. When all conditions are met, the data integration module 200 uploads the equipment status information of all circuit breakers through the connection in accordance with the pre-compiled processing sequence. After the front-end sampling actuator analyzes the equipment status, it selects whether to drive the related relay output to switch.

[0044] It is understandable that the modular situational awareness device 100 provided by the present application can flexibly expand a number of the digital quantity acquisition modules 300 according to different project requirements, compared to the traditional centralized dual power conversion device, and delegate all sampling and small-scale processing to the digital quantity acquisition module 300. The data integration module 200 only needs to set up the required modules in advance, process the data uploaded by the sampling module during operation and respond to external requirements, thereby greatly simplifying the system design and improving the overall project customization responsiveness of the controller. Therefore, the modular situational awareness device 100 can be flexibly matched according to different situation demand levels, and can adapt to systems with different load levels, as well as special customized scenarios with different numbers and configurations of incoming lines, solving the problem that traditional centralized devices are difficult to use universally.

The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and illustrated in the embodiments.
