[0037] The inventors discovered that data centers are an essential infrastructure for the financial industry's informatization. Banks across the country have numerous branches scattered throughout various cities, providing daily business services and ATM deposit and withdrawal operations. To ensure the normal and stable operation of various businesses within these branches, a small server room (data center) is typically built within each branch. This server room is equipped with power equipment such as UPS (Uninterruptible Power System), batteries, and various security, fire protection, environmental, and asset status sensors to ensure the safe operation of the server room infrastructure. Simultaneously, the bank's monitoring center monitors the operational status of the infrastructure at each branch. Since bank branch server rooms are usually unattended, various automated sensors are used to monitor the operational status of the on-site infrastructure. Data acquisition devices, battery inspectors, and leak detectors are among the key equipment used in this monitoring.

[0038] Traditional environmental monitoring systems for computer rooms on the market include monitoring platform software, data acquisition devices for network points, sensor controllers (such as water leakage controllers and air conditioner remote control repeaters), battery inspection instruments, battery acquisition sensors, switching power supplies and module boxes that power the monitoring equipment, etc. The entire environmental monitoring system has a wide variety of hardware devices, complex device functions, a large amount of wiring, and various devices transmit data through a bus, resulting in poor real-time acquisition, slow alarm response when equipment abnormalities occur, and high overall solution costs.

[0039] The current market offers various types of sensor devices, data acquisition devices, and power supply equipment for bank branches. Their purpose is to monitor the operating status of power equipment, temperature and humidity, toxic and harmful gas environments, smoke levels, air conditioning leaks, and the temperature and humidity control of air conditioning systems in the branch's computer room, as well as the status of IT (Information Technology) equipment assets in the server racks. Each sensor is an independent device from numerous manufacturers, and each device can only provide a single function. At the branch site, these devices need to be networked and connected, and each needs its own independent power supply. Finally, the communication and status lines of these devices must converge on the data acquisition device, where protocol conversion is performed, and the data is ultimately transmitted over the network to a remote monitoring platform for management and display.

[0040] The shortcomings of existing technologies are that various single-function sensor devices need to be installed at the site, and water leakage, infrared remote control repeaters, batteries, etc. also require dedicated controllers to collect and manage data from the sensors, and finally transmit the data to the data acquisition device via RS485; in addition, each device needs to be powered by a DC power supply, which leads to complex on-site installation and wiring, high costs, and very low data acquisition efficiency.

[0041] To resolve the above technical issues, please refer to the following: Figure 11 and Figure 12 This utility model innovates and improves upon these data acquisition devices. Specifically, this utility model provides a data acquisition device, which includes: a housing 17, a motherboard 2, the aforementioned bank branch monitoring data acquisition network 1000, and a switching power supply 1; wherein, the housing 17 is a square sheet metal housing 17, and the housing 17 is provided with several through holes for mounting the wired data transmission module 400; the housing 17 forms an accommodating space; the motherboard 2 is disposed in the accommodating space, and the bank branch monitoring data acquisition network 1000 is disposed on the upper surface of the motherboard 2; the switching power supply 1 matches the shape of the motherboard 2 and is electrically connected to the motherboard 2 and the wired data transmission module 400 of the bank branch monitoring data acquisition network 1000 respectively, for supplying power to the wired data transmission module 400 and the motherboard 2 circuit respectively.

[0042] Specifically, to enable a single data acquisition unit to handle data access from all peripherals and sensors in a single bank branch, an industrial-grade switching power supply 1 is integrated within the data acquisition unit. This power supply not only powers the unit itself but also provides power to external sensors, achieving dual functionality of single-wire power supply and data communication. The data acquisition unit, serving as a branch data collection device, is an independent host unit with a standard 1U height sheet metal structure. 1U (Unit) is a unit of measurement for the external dimensions of a server; therefore, the data acquisition unit is 44.45mm high, and its overall dimensions are 300mm (L) * 100mm (W) * 44mm (H).

[0043] In some preferred embodiments of this utility model, please refer to Figure 13The switching power supply 1 has a power of 60W, divided into two main branches. One branch supplies power to all components on the internal motherboard 2, using a DC-DC step-down circuit to reduce DC 12V to 3.3V for all onboard components, allocating 12W. The other branch first passes through overcurrent and short-circuit protection circuits and filtering circuits at the power output, and then distributes power to various external communication terminals of different attributes, providing power to different external devices, with a total allocation of 48W. For example, the external communication terminals may include intelligent sensors (such as intelligent temperature and humidity sensors) powered via RJ45 ports and connected to external devices via communication, hydrogen transmitters with Phoenix terminal interfaces, battery current modules with independent 2-pin power output interfaces, and independent sensor devices driven by external DO interfaces 6 (such as audible and visual alarms, light switches, etc.).

[0044] The schematic diagram of the DC-DC step-down circuit is as follows: Figure 2As shown, it includes a first capacitor C1, a second capacitor C2, a third capacitor C3, a fifth capacitor C5, a first inductor L1, a first resistor R1, a second resistor R2, a third resistor R3, and a first chip U1. One end of the first capacitor C1 is connected to the gate drive terminal of the first chip U1, and the other end of the first capacitor C1 is connected to the inductor terminal of the first chip U1. One end of the first inductor L1 is connected to the inductor terminal of the first chip U1, and the other end of the first inductor L1 is connected to a 3.3V operating voltage output. One end of the second capacitor C2 is connected to the 3.3V operating voltage output, and the other end of the second capacitor C2 is connected to the output feedback terminal of the first chip U1. One end of the third capacitor C3 and one end of the fifth capacitor C5 are connected to the 3.3V operating voltage output. The other end of the resistor and the other end of the fifth capacitor C5 are grounded for power filtering. The input terminal of the first chip U1 is connected to a 12V external voltage. One end of the first resistor R1 is connected to a 12V external resistor, and the other end of the first resistor R1 is connected to the enable terminal of the first chip U1. One end of the third resistor R3 is connected to a 3.3V operating voltage output, and the other end of the third resistor R3 is connected to the output feedback terminal of the first chip U1. One end of the second resistor R2 is connected to the output feedback terminal of the first chip U1, and the other end of the second resistor R2 is grounded to the ground terminal of the first chip U1. The first chip U1 is used to control the step-down voltage; preferably, it is a SY8120I step-down chip. It should be noted that the switching power supply module 1 includes a DC-DC power supply, which is used to provide operating voltage to the central management module 100. In another preferred embodiment, the switching power supply module 1 may also include an AC-DC module, one end of which is connected to an external AC power supply, and the other end of which is connected to the central management module 100, for converting the external AC power supply into DC power supply. Further details will not be elaborated here.

[0045] A further feature of this invention is that the outer casing 17 is provided with mounting ears 4, which are disposed on at least one side wall of the outer casing 17 and symmetrically arranged between each other, for screwing the data acquisition unit onto a vertical plane. This wall-mounted installation method does not occupy server room cabinet space, solving the problem of minimizing space occupation for a single unit on-site. Specifically, by installing mounting ears 4 on both sides of the data acquisition unit, the equipment can be screwed and installed using a wall-mounted method, without occupying server room cabinet space. Those skilled in the art will understand that the mounting ears 4 can be parallel to the width direction of the data acquisition unit and horizontally arranged, or parallel to the height direction of the data acquisition unit and vertically arranged, or inclined at a certain angle to the horizontal direction, thereby adapting to different angled fixing planes. Simultaneously, the mounting ears 4 can be disposed on the side of the data acquisition unit, or on the upper and lower surfaces of the data acquisition unit, and mounting ears 4 with different inclination angles can be disposed simultaneously, thus allowing multiple mounting ears 4 for fixing to be disposed on one side, improving suspension stability.

[0046] Furthermore, this utility model provides a bank branch monitoring data acquisition network 1000, such as... Figure 1 As shown, it includes: a central management module 100, an environmental condition detection module 200, a short-range wireless control module 300, and a wired data transmission module 400; wherein, the environmental condition detection module 200 is connected to the central management module 100, used to detect environmental parameters in the space, and output environmental data signals to the central management module 100; the short-range wireless control module 300 is connected to the central management module 100, collects and stores remote control memory signals to the central management module 100, and collects the remote control memory signals of the central management module and outputs them to the environment during output; The wired data transmission module 400 is connected to the central management module 100 and is used to output external control signals to the central management module 100. The central management module 100 is used to collect and store the remote control memory signal in the short-range wireless control module 300, the external control signal in the wired data transmission module 400, and the environmental data signal in the environmental condition detection module 200, and output the remote control memory signal, the external control signal, and / or the environmental data signal to the short-range wireless control module 300, and output the external control signal and / or the environmental data signal to the wired data transmission module 400.

[0047] The data acquisition unit's housing 17 has several through holes, and the environmental condition detection module 200 is disposed in at least one of these through holes, allowing it to detect environmental parameters in the bank branch environment. The shape of each through hole corresponds to the detection end or probe of the environmental condition detection module 200. The environmental condition detection module 200 converts environmental data into analog or digital signals and outputs them to the central management module 100 for unified data management. The short-range wireless control module 300, when outputting, can transmit wireless control signals into the environment. In another preferred embodiment, the input can be programmed into a learning mode. In learning mode, the short-range wireless control module 300 memorizes remote control signals provided by the user and reads these signals as commands when needed, thereby improving the usability of the data acquisition network and the data acquisition unit.

[0048] Furthermore, the environmental condition detection module 200 includes a temperature and humidity sensing detection unit 210 and a regional water leakage detection unit 220; the temperature and humidity sensing detection unit 210 is connected to the central management module 100 and is used to detect the ambient temperature and humidity and output temperature and humidity signals to the central management module 100; the regional water leakage detection unit 220 is connected to the central management module 100 and is used to output a water leakage warning signal to the central management module 100 when water leakage is detected.

[0049] In a preferred embodiment of this utility model, the area leakage detection unit 220 includes a leakage rope, a collector, and a leakage detection circuit. One end of the leakage rope is connected to the target machine; when the target machine leaks water, the leakage rope absorbs the leaked water. The collector has a detection opening and is electrically connected to the leakage detection circuit. The other end of the leakage rope is inserted into the opening of the collector to detect the moisture content of the leakage rope through the detection opening. When the leakage rope contains water, a leakage signal is output to the leakage detection circuit. The leakage detection circuit collects the leakage signal and outputs a leakage warning signal to the central management module 100.

[0050] Specifically, the target machine for detection is an external object that needs to be protected against water leakage. For example, the target machine can be a refrigeration air conditioner or other equipment in a computer room that may cause water leakage. The water leakage detection circuit is as follows: Figure 4As shown, it includes: a collector port JI4, resistors R91 (91st), R97 (97th), R98 (98th), R99 (99th), R100 (100th), R101 (101st), R102 (102nd), R109 (109th), an optocoupler U25, capacitor C85 (85th), a DIP switch S2, and a dual operational amplifier U29. The collector port JI4 is connected to the collector and is used to detect leaks. It can be equivalent to a two-port jumper. The first end of the collector port JI4 is connected to the first non-inverting input of the dual operational amplifier U29, and the second end of the collector port JI4 is grounded. The collector is positioned between the first and second ends of the collector port JI4, and the collector is located below the leak rope. One end of the first 102 resistor R102 is connected to a 12V power supply. The other end of the first 102 resistor R102 is connected to one end of the first 101 resistor R101. The other end of the first 101 resistor R101 is connected to one end of the 99th resistor R99. The other end of the 99th resistor R99 is connected to one end of the 98th resistor R98. The other end of the 98th resistor R98 is grounded. The DIP switch S2 is a four-position DIP switch S2. The first position of the DIP switch S2... The first terminal of the DIP switch S2 is connected to the common terminal of the first 102 resistor R102 and the first 101 resistor R101. The second terminal of the DIP switch S2 is connected to the common terminal of the first 101 resistor R101 and the ninety-ninth resistor R99. The third terminal of the DIP switch S2 is connected to the common terminal of the ninety-ninth resistor R99 and the ninety-eighth resistor R98. The fourth terminal of the DIP switch S2 is connected to a 12V power supply. The first inverting input terminal of the dual operational amplifier U29 is connected to the third terminal of the DIP switch S2. The first output terminal of the dual operational amplifier U29 is connected to one end of the first 100 resistor R100. The other end of the first 100 resistor R100, the power supply terminal of the dual operational amplifier U29, one end of the first 109 resistor R109, and one end of the eighty-fifth capacitor C85 are each connected to a 12V power supply. The other end of the eighty-fifth capacitor C85 is grounded. The second non-inverting input terminal of the dual operational amplifier U29 is connected to the first output terminal of the dual operational amplifier U29, and the second inverting input terminal and the second output terminal of the dual operational amplifier U29 are connected to the other end of the first resistor R109.The positive terminal of the emitting diode of the optocoupler U25 is connected to the second output terminal, the negative terminal of the emitting diode of the optocoupler U25 is grounded, the collector terminal of the optocoupler U25 is connected to the leakage detection terminal of the central management module 100, and the emitting terminal of the optocoupler U25 is grounded. One end of the ninety-first resistor R91 is connected to the collector terminal of the optocoupler U25, and the other end of the ninety-first resistor R91 is connected to the operating voltage. One end of the ninety-seventh resistor R97 is connected to the first non-inverting input terminal of the dual operational amplifier U29, and the other end of the ninety-seventh resistor R97 is grounded.

[0051] The leakage detection circuit integrates the functions of a leakage controller. By toggling the position switch on the DIP switch S2, the voltage input to the first inverting input terminal of the dual operational amplifier U29 changes accordingly, supporting three levels of sensitivity adjustment to detect the state of the leaking rope. The data acquisition port JI4 can be directly connected to the leaking rope. When there is moisture on the leaking rope, the data acquisition port JI4 can be considered a short circuit. Specifically, the leakage controller sets the leakage sensitivity through three DIP modes (00, 01 / 10, and 11) on the two-position DIP switch S2, adjusting the impedance threshold value for triggering leakage on the leaking rope. A comparator circuit then compares and triggers the output, which is then driven by an optocoupler for signal isolation before being transmitted to the MCU's GPI for detection, thus achieving impedance detection of the analog leaking rope. The data acquisition unit can directly process the analog signal from the leaking rope, eliminating the need for a separate leakage controller component and integrating the controller's functions into the data acquisition unit itself. This feature minimizes equipment costs and simplifies the installation and wiring of the leak detection device; only a leak detection rope needs to be connected to the outside of the collector.

[0052] In another preferred embodiment of this utility model, the central management module 100 on the motherboard 2 is directly connected to a temperature and humidity sensing unit via a signal transmission line, and its circuit diagram is shown below.

[0065] Further improvements to this invention address the problems of numerous, complex, and inefficient data acquisition devices in bank branch infrastructure monitoring systems. To improve the real-time responsiveness of the bank branch environmental monitoring system and reduce the complexity and cost of monitoring equipment, this invention employs a highly integrated approach to achieve monitoring and acquisition functions. It utilizes a single independent MCU for management. The central management module 100 includes a microcontroller chip, specifically an ARM Cortex M4 RISC chip, which acquires and processes various data. This chip provides a 240MHz clock frequency, 512KB of SRAM, and 1MB of on-chip Flash, running an RTOS real-time operating system to enable rapid power-on reset and startup of the device, efficient data acquisition, and ensure real-time data transmission. Under the coordination of a single controller, sensor data is acquired, processed, converted, buffered, and displayed locally. Simultaneously, the integrated and processed data is output to the upper layer via the northbound interface of the network bus, achieving the most efficient and cost-effective monitoring and acquisition function. By employing a single independent microcontroller unit (MCU) chip, the system manages sensor probe data acquisition, processing, protocol conversion, and the addition, deletion, modification, and querying of battery sensor modules, enabling a single unit to monitor the entire network infrastructure. The device utilizes an ultra-low-power MCU chip running a real-time operating system (RTOS) for data acquisition and processing. The MCU on motherboard 2, running the RTOS, ensures rapid power-on reset and startup, efficient data acquisition, and real-time data transmission. This device incorporates a built-in web server for managing the acquisition equipment and external sensors, displaying data, and configuring the network; significantly improving the efficiency of on-site equipment data debugging; and supporting system and module firmware upgrades via a web browser accessing the acquisition device's web page. The acquisition device also supports acquiring and processing data from southbound sensor devices using various protocols, converting it into northbound standard Modbus TCP, SNMP, and MQTT protocol data for use with the upper-level monitoring system. Since the monitoring system only needs to read the data interface of one device to obtain data from all environmental monitoring devices and sensors in the network, this significantly reduces acquisition time and improves the system's real-time response capability.

[0066] Furthermore, the front and rear sides of the housing 17 of the data acquisition device of this utility model are respectively provided with a plurality of through holes. The through holes on the front side of the housing 17 are respectively used to house the temperature and humidity sensing unit 210, the near-field wireless control module 300, and other modules for user interaction. That is, the temperature and humidity sensing unit 210 and the near-field wireless control module 300 are located on the motherboard 2 near the front side of the housing and are arranged corresponding to the positions of the through holes. For details, please refer to the following: Figure 11and Figure 12 The motherboard 2 is an L-shaped motherboard 2, and the shape of the switching power supply 1 corresponds to the shape of the motherboard 2.

Correspondingly, the through hole on the rear side of the housing has sequentially arranged for fixing the communication ports of the wired data transmission module 400 and the collector structure 7 of the area water leakage detection unit 220. For example, it may include an RJ11-6 interface for setting up an XBUS serial bus; a digital output port, the port being 3PIN-5.08mm; a through hole for setting up the collector structure of the area leakage detection unit 220; two digital input ports 8, DI1 and DI2, the ports being 4PIN-5.08mm; four COM ports 9, COM1, COM2, COM3, and COM4, ​​the ports being 3PIN-5.08mm; and a COM+LAN multiplexed port 10, the port being RJ45. Then, the analog-digital input / output unit 410, the network interface unit 420, and the intelligent device communication bus unit 430 of the wired data transmission module 400 are located on the motherboard 2 near the rear side.

[0067] Furthermore, please refer to the following: Figure 10 , Figure 11 , Figure 12The bank branch monitoring data acquisition network 1000 described in this utility model may further include a reset button 15 for resetting, an LED indicator 14 for indicating the working status of the circuit, and a case and / or DIP switch S2 for controlling the switching of the working status. When the reset button 15, the LED indicator 14 for indicating the working status of the circuit, and the case and / or DIP switch S2 for controlling the switching of the working status are implemented, their circuits are also set on the main board 2 and are disposed on the surface of the housing through through holes in the housing. Further details will not be elaborated here. It should be noted that the above-mentioned modules in this utility model can be implemented simultaneously in the data acquisition device, and the corresponding modules mentioned can be added, their structural positions adjusted, or deleted according to the specific application scenario. By adopting a highly integrated all-in-one design, multiple business function modules are integrated, including temperature and humidity sensor devices with built-in I2C, regional water leakage controller function, battery smart gateway (inspection instrument) function, infrared air conditioner remote control repeater function, 4-channel serial bus function, and analog and digital input and output functions of AI, DI, and DO. After these functions are integrated, there is no need to add additional dedicated controllers for these sensors outside the data acquisition unit to realize function expansion, reducing the number of devices and reducing the complexity of installation and construction.

The data acquisition device 31 is used to collect monitoring signals from each of the lower-level sensors 40 and output the monitoring signals to the network switch 21. The network switch 21 is connected to the host monitoring platform 20 and is used to interact with the host monitoring platform 20, upload the monitoring signals to the host monitoring platform 20, and receive control commands transmitted by the host monitoring platform 20. The host monitoring platform 20 is used to display the monitoring signals and output control commands generated by user interaction to the network switch 21. Specific implementations of the data acquisition device 31 are described in detail below and will not be repeated here. This application supports the collection and calculation of data from southbound sensor devices using various protocols, and converts the data into data using northbound standard Modbus TCP, SNMP, and MQTT protocols, providing it to the upper-layer monitoring system. Because the monitoring system only needs to read the data interface of one device to obtain data from all environmental devices and sensors in the network, this can greatly shorten the collection time and improve the system's real-time response capability.

It provides these modules with power supply, addressing management, intelligent group management, data acquisition, acquisition parameter configuration, periodic automatic and manual internal resistance measurement, module data calibration, module firmware online upgrade, module sleep / wake-up, monitoring data display, and business alarm functions.

These serial buses can all be set to transparent data transmission mode or protocol data parsing mode.

[0078] It integrates one AI analog input (4-20mA, 0-5V), two DI digital inputs, and one relay DO output. It can directly connect to various types of digital input / output devices and supports the associated actions between these status devices. Each port can provide external power, solving the power supply problem for external devices. This allows a single data acquisition unit to handle the access and power supply for all devices at the network site, significantly reducing the overall number of devices and the amount of wiring work.

[0079] The motherboard 2 uses a 32-bit ARM Cortex®-M4 RISC MCU as the main chip to acquire and process various data. This chip provides a 240MHz main frequency, 512KB SRAM and 1MB on-chip Flash, running an RTOS real-time operating system to achieve rapid power-on reset and startup of the device, efficient data acquisition, and ensure data real-time performance. The battery smart gateway's functions and port expansion capabilities (DI interface, DO interface 6, AI interface) are highly integrated, solving the complex transmission architecture problem of the device and significantly reducing the overall hardware cost of the solution.
