Description

Technical Field

[0001] This utility model relates to the field of alarm technology for temperature and pressure monitoring equipment, and in particular to a temperature and pressure monitoring equipment with alarm function. Background Technology

[0002] Temperature and pressure monitoring equipment is an instrument used to collect and monitor the temperature and pressure parameters of the environment or a specific object in real time. It has data recording, transmission, and abnormal alarm functions. The core consists of temperature sensors (such as thermocouples and RTDs), pressure sensors (such as strain gauges and capacitive sensors), data processing units (MCU / PLC), display / storage modules (LCD / SD card), and communication modules (RS485 / LoRa / NB-IoT), which can realize real-time parameter display, historical data query, and remote monitoring.

[0003] Widely used in industrial production (chemical reactors, power equipment), energy storage and transportation (oil and gas pipelines, storage tanks), building environment (HVAC systems), medical (laboratory temperature control equipment), transportation (cold chain logistics, vehicle tires), and other fields, these devices ensure safe equipment operation, optimize process flows, and reduce energy consumption through high-precision (temperature ±0.1℃, pressure ±0.5%FS) and high-stability monitoring. Some devices support IoT access, possess intelligent analysis and early warning functions, and are adaptable to complex working conditions such as explosion-proof, waterproof, and high / low temperature environments.

[0004] Current temperature and pressure monitoring equipment has certain limitations in use. When the system detects that the temperature or pressure data of the monitored object exceeds a preset threshold, it is often difficult to quickly determine whether the anomaly is caused by an actual malfunction in the monitored equipment itself or by an abnormality in one or more monitoring units within the temperature and pressure monitoring system. Such anomalies may include various forms of failure such as sensor failure, signal acquisition deviation, data drift, communication transmission interruption, calibration errors, or environmental interference. Because the source of the anomaly cannot be effectively distinguished, maintenance personnel often need to invest more time and resources in troubleshooting, which not only reduces the efficiency of fault identification and location but may also lead to false alarms or missed alarms. This, in turn, affects the accuracy and timeliness of the overall equipment status assessment, ultimately resulting in delayed maintenance decisions, increased processing costs, and potentially even increased equipment operational risks.

[0026] like Figure 1 - Figure 5 As shown, a temperature and pressure monitoring device with alarm function mainly includes a temperature and pressure monitoring main housing 1, connecting pipes 2, a display instrument 3, and a detection module 4.

The quick-release connector 5 allows for rapid assembly and disassembly of the entire alarm system, facilitating maintenance and replacement.

[0028] An audible and visual alarm system is installed on the upper part of the alarm control box 6 to provide audible and visual warnings in case of abnormal temperature or pressure. This system includes an alarm speaker 9 and an alarm light 11. A mounting base 7 with an "Ω"-shaped cross-section is fixed to the upper surface of the alarm control box 6 and is bolted to the box body, providing good vibration resistance and stability. An audible control base 8 and a visual control base 10 are respectively mounted on the upper part of the mounting base 7. The upper end of the audible control base 8 is connected to the alarm speaker 9 for emitting an alarm sound; the upper end of the visual control base 10 is connected to the alarm light 11 for emitting a flashing light signal. The audible control base 8 and the visual control base 10 are interconnected via a series interface 12, supporting the expansion of more alarm devices.

[0029] The alarm control box 6 and the quick-release connector 5 adopt a split design, with side strips at the connection point and secured by bolts to ensure structural sturdiness. Sealing strips are also embedded at the joints for dust and water protection. The sound control unit 8 and the light control unit 10 are also bolted to the mounting base 7. The alarm speaker 9 and alarm light 11 are connected to their respective control units via threaded interfaces, ensuring reliable installation and easy replacement. All wires are led into the alarm control box 6 from the bottom of the control unit, with rubber sleeves installed at the wire holes for protection and sealing.

[0030] The device supports the coordinated operation of multiple temperature and pressure monitoring main housings 1, each equipped with an independent audible and visual alarm system. These alarm systems can be connected via a serial interface 12 to achieve system cascading and centralized control, facilitating unified monitoring and management in large equipment or complex systems.

[0031] Connecting pipes 2 are installed on the left and right sides of the temperature and pressure monitoring main housing 1, respectively, for connecting the measured medium; display instrument 3 is embedded in the front panel of the temperature and pressure monitoring main housing 1 for real-time parameter display; detection module 4 is set at the lower end of the temperature and pressure monitoring main housing 1, integrating temperature and pressure sensors. A quick-release connector 5 ("L"-shaped obtuse angle structure) is connected to the rear opening of the temperature and pressure monitoring main housing 1 to ensure a secure connection; its internal wiring holes are used for subsequent power and signal cable routing. The alarm control box 6 is connected to the top of the quick-release connector 5, adopting a split design; the connection is fixed by side strips and bolts, and a sealing strip is embedded in the joint for dust and water protection; the control box is pre-installed with a microprocessor, battery, and memory. Mounting bracket 7 (Ω-shaped cross-section, vibration-resistant and stable) is bolted to the upper surface of the alarm control box 6. Sound control bracket 8 and light control bracket 10 are bolted to the upper end of mounting bracket 7. Alarm speaker 9 is connected to the upper end of sound control bracket 8 via a threaded interface, and alarm light 11 is connected to the upper end of light control bracket 10 via a threaded interface. Sound control bracket 8 and light control bracket 10 are connected via a serial interface 12, supporting the expansion of more alarm devices. All wires are introduced into the alarm control box 6 from the bottom of sound control bracket 8 and light control bracket 10, with rubber sleeves installed at the wire holes for protection and sealing. Power and signal wires are routed through the internal wiring holes of the quick-release connector 5. When multiple temperature and pressure monitoring main housings 1 work together, each independent sound and light alarm system is interconnected via the serial interface 12 to achieve system cascading and centralized control.

[0032] The device is connected to the measured medium system via connecting pipe 2, transmitting pressure and temperature. The internal sensors of detection module 4 collect temperature and pressure parameters in real time, and display instrument 3 displays the current temperature and pressure values. Detection module 4 transmits the collected parameters to the microprocessor in alarm control box 6. The microprocessor processes the data and compares it with a set threshold, and the memory synchronously stores the monitoring data. When the monitoring data exceeds the set threshold, alarm control box 6 triggers the sound and light alarm system; alarm speaker 9 emits an alarm sound, and alarm light 11 emits a flashing light signal. Multiple devices are cascaded through serial interface 12 to achieve centralized control and unified monitoring management.

[0033] Alarm Procedure: The temperature and pressure sensors inside detection module 4 collect the temperature and pressure parameters of the measured medium in real time. The collected temperature and pressure parameters are transmitted to the microprocessor in the alarm control box 6 via signal lines (through the wiring holes inside the quick-release connector 5). The microprocessor compares the real-time parameters with preset alarm thresholds. If the parameters exceed the thresholds, an abnormal state is determined. The microprocessor sends control signals to the sound control unit 8 and the light control unit 10. The sound control unit 8 drives the alarm speaker 9 to emit an alarm sound, and the light control unit 10 drives the alarm light 11 to emit a flashing light signal, achieving synchronized sound and light alarms. If there are multiple systems, the system that triggers the alarm transmits the signal to other cascaded systems through the serial interface 12, achieving cascaded alarms.

[0034] Sound control base 8: Bolted to the upper end of mounting base 7, the upper end is connected to alarm speaker 9 via a threaded interface. It receives signals from the microprocessor and drives the speaker to emit sound. It is also connected to light control base 10 via serial interface 12.

Light control base 10: Bolted to the upper end of mounting base 7, the upper end is connected to alarm light 11 via a threaded interface. It receives signals from the microprocessor and drives alarm light 11 to flash. It is also connected to sound control base 8 via serial interface 12. Alarm light 11: Connected to light control base 10 via a threaded interface, it emits a flashing light signal under the control base's drive, serving as a visual warning. Serial interface 12: Connects sound control base 8 and light control base 10, supporting the expansion of more alarm devices and enabling cascading of multiple alarm systems, facilitating centralized control of large equipment or complex systems.
