[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1

[0019] Please refer to Figure 1-3As shown, this utility model provides a wired remote water meter data centralized acquisition device, including a waterproof rectangular housing 1. The surface of the housing 1 is provided with a display screen 2 and operation buttons 3. The bottom of the housing 1 is provided with a cable interface. The main control module 7 is installed inside the housing 1. The main control module 7 uses an MCU chip as the core processor. The main control module 7 is connected to a communication module 8, a power module 9 and a data interface module 10. The communication module 8 includes an RS485 communication unit, an MBUS bus communication unit and a wireless 4G transmission unit. The power module 9 includes an AC-DC power converter and a backup battery. The data interface module 10 is provided with multiple interfaces.

[0020] Specifically, when the wired remote water meter data centralized acquisition device is working, multiple interfaces of the data interface module 10 can be connected to each water meter via shielded twisted-pair cables through the cable interface at the bottom of the housing 1. The AC-DC power converter of the power module 9 can be connected to the mains power supply, and the backup battery can be used for power outage backup. The operator can set parameters through the display screen 2 and operation buttons 3. The MCU chip of the main control module 7 can control the RS485 communication unit and the MBUS bus communication unit to collect water meter data. After processing, the data is uploaded to the server through the corresponding port of the radio base station via the wireless 4G transmission unit, realizing centralized wired remote transmission and management of multiple water meter data. Thus, through the above structure, the efficiency of water meter data acquisition and the level of intelligent management can be effectively improved.

[0021] The main control module 7 has a built-in data cache unit that stores the water meter data collected periodically. This data cache unit can temporarily save the data in the event of communication interruption or system failure, thus avoiding data loss and ensuring data integrity and continuity. Once communication is restored, the data can continue to be transmitted, thereby improving the reliability of data collection.

[0022] The RS485 communication unit and the MBUS bus communication unit connect multiple water meters via shielded twisted-pair cables to collect water meter data. The wireless 4G transmission unit connects to the host computer via a radio base station for remote transmission of processed data. The combination of these two components enables stable data collection from multiple water meters and reliable long-distance transmission. It has strong anti-interference capabilities and high transmission efficiency, meeting the data collection and remote management needs of intelligent water systems.

[0023] The cable interface at the bottom of housing 1 is a waterproof aviation plug. The waterproof aviation plug includes a power interface 4, an RS485 interface 6, and an Ethernet interface 5. The waterproof aviation plug at the bottom of housing 1 integrates the power interface 4, RS485 and MBUS bus interfaces 6, and wireless 4G transmission interface 5, which can achieve waterproof and dustproof connection, ensure reliable access and protection of power and data transmission lines, and facilitate stable operation of the equipment in humid and other harsh environments.

[0024] The system includes at least 50 RS485 and MBUS bus interfaces, each of which connects to a water meter independently. This meets the centralized and synchronous data collection needs of multiple water meters in large residential areas and buildings, significantly improving data collection efficiency, simplifying cabling structure, and reducing networking costs.

[0025] The housing 1 has an anti-interference shielding layer inside, which encloses the main control module 7, communication module 8 and data interface module 10. This anti-interference shielding layer inside the housing 1 can effectively block external electromagnetic interference, ensure the stability of data acquisition, processing and transmission, and improve the reliability of the equipment in complex electromagnetic environments.

[0026] Working principle: First, multiple interfaces of the data interface module 10 can be connected to each water meter via shielded twisted-pair cables through the cable interface at the bottom of the housing 1. Data is collected by the RS485 communication unit and the MBUS bus communication unit. At the same time, it is connected to the host computer through the wireless 4G interface 5 to realize the remote transmission of processed data. During operation, the AC-DC converter of the power module 9 is connected to the mains power supply, and the backup battery is used for power failure backup. The operator sets parameters through the display screen 2 and operation buttons 3. The MCU chip of the main control module 7 can control data acquisition and processing. The built-in data cache unit can store the periodically collected data to ensure that the data is not lost when communication is interrupted. The anti-interference shielding layer inside the housing 1 covers the core module, which can improve the reliability of the equipment in complex environments. Ultimately, it realizes the centralized acquisition, stable transmission and intelligent management of data from multiple water meters, thereby completing the entire operation process.
