With technological advancements, pressure monitoring equipment is evolving towards digital display, real-time performance, multi-functional integration, and data interaction support to meet the dynamic pressure management needs of various fields.

[0003] Currently, negative pressure monitoring instruments on the market have many problems. Some instruments use pointer displays, which are not intuitive and accurate enough, and are prone to human error in reading. This makes it difficult to quickly obtain pressure information, increases the difficulty of operation and the probability of error. At the same time, the existing negative pressure monitoring instruments have relatively simple functions. Most of them can only perform simple measurement and display of pressure values ​​and lack functions such as data recording, over-limit alarm, and remote transmission. They cannot meet the requirements of modern production and management for intelligent and information-based equipment. Utility Model Content

The front of the housing 1 has a display screen mounting slot and a keypad 11. The pressure sensing module 4 includes a high-precision piezoresistive pressure sensor 401. The piezoresistive pressure sensor 401 is installed on the upper surface of the main board 3. The air inlet of the piezoresistive pressure sensor 401 is connected to the negative pressure environment to be measured through an air guide pipe 402.

[0036] The data processing module 5 uses a high-performance microprocessor chip, which is mounted on the upper surface of the motherboard 3. The microprocessor chip is connected to the pressure sensing module 4, display module 6, alarm module 7, storage module 8, and communication module 9 via circuitry. The data processing module 5 receives the electrical signal output from the pressure sensing module 4, performs analog-to-digital conversion and data calculation, converts the pressure signal into the corresponding pressure value, and analyzes and judges the pressure value according to preset parameters and algorithms to control the working status of each functional module. The display module 6 uses a Chinese LCD screen, which is mounted in the display mounting slot. The Chinese LCD screen can display the current negative pressure value, pressure unit, measurement time, and equipment working status information in real time with a clear and intuitive Chinese interface.

[0037] The alarm module 7 includes a buzzer alarm 701, which is installed on the front of the housing 1. When the data processing module 5 determines that the current negative pressure value exceeds the preset alarm threshold, the buzzer emits a loud alarm sound to remind the operator to take timely measures. The alarm threshold can be set and adjusted through the operation buttons to meet the alarm needs in different scenarios. The storage module 8 uses a large-capacity memory and supports CSV format data storage. The storage module 8 is installed on the front of the motherboard 3. The storage module is used to store pressure measurement data, alarm records, equipment parameters and other information. The operator can query historical data through the operation buttons.

[0038] The communication module 9 integrates multiple communication interfaces, including an RS485 interface and a USB interface. The communication module 9 also includes a wireless communication component 903. The RS485 interface and the USB interface are located on the side of the housing 1 for easy wired connection with other devices. The wireless communication component 903 can realize wireless data transmission with mobile terminals, enabling operators to obtain negative pressure monitoring information anytime and anywhere, and realize remote monitoring and management. The power supply module 10 includes a rechargeable lithium battery 1001 and a charging port 1002. The lithium battery 1001 is installed inside the housing 1.

[0039] It should be noted that before use, the power level of the lithium battery 1001 must be confirmed, and the alarm threshold must be entered through the keypad 11.

[0040] The working principle of the above embodiment is as follows: In use, the air duct 402 of the pressure sensing module 4 is connected to the environment to be measured. The piezoresistive pressure sensor 401 of the pressure sensing module 4 begins to sense the pressure change of the negative pressure environment and converts the pressure signal into an electrical signal, which is then transmitted to the data processing module 5. After receiving the electrical signal, the data processing module 5 performs analog-to-digital conversion and data calculation processing, converts the pressure signal into the corresponding pressure value, and compares it with the preset alarm threshold. If the current negative pressure value does not exceed the alarm threshold, the data processing module 5 controls the display module 6 to display the current negative pressure value, pressure unit, measurement time, and other information in real time in a Chinese interface. If the current negative pressure value exceeds the alarm threshold, the data processing module 5 immediately triggers the alarm module 7, and the buzzer alarm 701 sounds an alarm to remind the operator.

[0041] The data processing module 5 stores pressure measurement data, alarm records, and other information into the storage module 8 at set time intervals. Operators can use the keypad 11 to query historical data and adjust alarm thresholds on the display module 6. When it is necessary to transmit instrument data to external devices, wired transmission can be achieved through the RS485 interface 901 and the USB interface 902, or wireless connection can be established with the remote monitoring center or mobile terminal through the wireless communication component 903, so as to realize remote data transmission and monitoring management, and meet the requirements of modern production and management for intelligent and information-based equipment.
