Technical Field

[0001] This utility model relates to the field of gas equipment monitoring technology, specifically a monitoring and early warning terminal device for industrial and commercial users. Background Technology

[0002] Traditional gas equipment monitoring systems have the following problems:

[0003] 1. Insufficient real-time performance: Key parameters such as pipeline pressure, flow rate, and temperature cannot be collected in real time, making it difficult to detect pressure loss, overpressure, or micro-leakage in a timely manner.

[0004] 2. Weak security measures: There is a lack of effective monitoring for illegal disassembly of gas meters, loose flanges, or gas theft.

[0005] 3. Low level of automation: It relies on manual inspection, and the fault diagnosis and early warning response are delayed.

[0006] In the existing technology, patents ZL202420218805.2 and ZL202222706523.0 involve some gas monitoring devices, but they do not solve problems such as multi-parameter collaborative monitoring, IoT integration, and anti-theft gas linkage. Therefore, a more intelligent and comprehensive solution is urgently needed. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a monitoring and early warning terminal device for industrial and commercial users, which solves the problem of insufficient real-time performance: key parameters such as pipeline pressure, flow rate, and temperature cannot be collected in real time, making it difficult to detect pressure loss, overpressure, or micro-leakage in a timely manner.

[0009] Preferably, the flow meter is equipped with an electronic seal, and the Bluetooth communication module is connected to the electronic seal via a signal, and the pressure transformer is connected to the Bluetooth seal via a signal.

[0010] Preferably, the gas intelligent monitoring host is equipped with an explosion-proof antenna and a power cord.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-2 This utility model provides a technical solution: a monitoring and early warning terminal device for industrial and commercial users, including a gas intelligent monitoring host 1, a Bluetooth communication module 2 on the upper wall of the gas intelligent monitoring host 1, a combustible gas concentration alarm 3 on the gas intelligent monitoring host 1, and a pressure transmitter 4, a temperature transmitter 5, a flow meter 6 and a pressure transformer 7 connected to the gas intelligent monitoring host 1 via signals.

[0017] As a preferred technical solution, the flow meter 6 is further equipped with an electronic seal 8, the Bluetooth communication module 2 is connected to the electronic seal 8 via a signal, and the pressure transformer 7 is connected to the Bluetooth seal 8 via a signal.

[0018] As a preferred technical solution, the gas intelligent monitoring host 1 is further equipped with an explosion-proof antenna 9 and a power cord 10.

[0019] It should be noted that for industrial and commercial users who have already installed gas leak alarm controllers, a pressure sensor should be installed on the main pipeline after the meter to collect pipeline pressure data in real time and monitor the pipeline pressure status. The intelligent monitoring controller for gas-using equipment connects to combustible gas detectors and pressure sensors, and collects data from each sub-device in real time. This data is uploaded to the system platform via the Internet of Things (IoT), where users can view detector concentration data, pipeline pressure data, and valve status in real time.

[0020] By installing intelligent monitoring terminals on gas equipment of large industrial and commercial gas users, the gas equipment can be monitored 24 hours a day. The fluctuation values ​​and curves of pressure and flow can reflect the operation of the pipeline network or users, and the status of gas equipment can be analyzed and reliability assessed. This enables automatic diagnosis of equipment status, early warning of equipment failures, and early handling.

[0021] The lack of real-time monitoring of pipeline pressure means that management personnel cannot obtain timely information regarding pressure loss or overpressure, posing a safety hazard. Monitoring pipeline pressure can also help determine if there is a leak, especially a minor one. The gas and combustible gas alarms provide synchronized warnings. For example, if a flow meter is removed and a minor leak occurs, the combustible gas alarm above the flow meter can detect whether the flow meter has been illegally removed or if a flange has been removed, causing the leak.

[0022] The communication control host has cover-opening alarm and low battery alarm functions. The host itself reports the status of the host, its associated lead seal, and transformer to the alarm data management backend twice a day. The host has a built-in lithium battery with a lifespan of ≥2 years and an external 4G communication antenna. Maintenance and repair reports are submitted via QR code scanning. The host and Bluetooth slave unit communicate using encrypted Bluetooth. The host and transformer are connected via signal cable.

[0023] The pressure transducer is slightly larger than the bolt hole diameter, monitoring the flange bolt preload to determine the flange disassembly status. The transducer senses the flange bolt and nut preload in real time, monitoring the flange sealing status and reducing the risk of flange leakage.

[0024] Electronic alarm seals are used to encapsulate gas meter counters, meter heads, flanges, and other locations. When the Bluetooth seal is short-circuited, powered off, or lost, the feedback signal is transmitted via Bluetooth to the communication control host for analysis and processing. The alarm signal is then uploaded to the gas inspection alarm platform via the 4G network.

[0025] It should be noted that: pressure transmitters (monitoring the upper / lower limit of pipeline pressure, alarm values ​​are 1.2P2 and 0.6P2 respectively, and shut-off values ​​are 1.2Pf and 0.3Pf respectively); temperature transmitters (low temperature alarm T≤5℃, heat tracing lower limit T≤0℃); flow meters (overflow alarm Q≥Qb, shut-off threshold 1.5Qb; low flow alarm Q≤5%Qb); and combustible gas detectors (leakage concentration ≥1% alarm, ≥2.5% trigger shut-off).

[0026] Intelligent monitoring controller: Connects to sensors, collects data in real time, and uploads it to the cloud platform via 4G / Bluetooth.

[0027] Pressure transducer (monitors flange bolt preload and determines flange disassembly status);

[0028] Electronic alarm lead seal (encapsulates meter counters, triggering platform alarm when wires are disconnected or lost).

[0029] Multi-parameter collaborative monitoring: Improves the accuracy of leak detection by cross-validating data of pressure, flow rate, temperature, and combustible gas concentration;

[0030] Anti-theft gas linkage mechanism: The pressure transformer is combined with the Bluetooth lead seal to monitor unauthorized disassembly in real time;

[0031] Low power consumption design: The main unit has a built-in lithium battery with a lifespan of ≥2 years and supports low battery alarm;

[0032] High-frequency data acquisition: The flow meter supports high-frequency readings (once every 3 seconds) to capture instantaneous anomalies.

[0033] Install a pressure transmitter on the main pipeline after the gas meter, and install pressure transformer plates at the flange.

[0034] Combustible gas detectors are deployed above flow meters to monitor for unauthorized removal or leaks;

[0035] The intelligent monitoring host integrates a 4G communication module, connects to mains power, and is equipped with a backup power supply.

[0036] Data Flow

[0037] Sensor data is transmitted to the controller via a 4-20mA signal or Bluetooth.

[0038] The controller encrypts the data and uploads it to the cloud platform, automatically sending an SMS notification when a threshold alarm is triggered.

[0039] The platform generates alarm records and assigns patrol tasks, and law enforcement officers scan the code on-site to report the handling results.

[0040] Leakage warning: Sudden pressure drop + increase in combustible gas concentration → Leakage detected, triggering shut-off valve to close;

[0041] Gas theft detection: Flow meter removed → Pressure transformer detection flange loose + lead seal broken wire → Platform alarm synchronized.
