Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, the wireless steam drain valve parameter monitoring system provided by the utility model comprises: the device comprises a pre-valve temperature and pressure sensor S2, a post-valve temperature sensor S1, a digital-to-analog conversion module U1, a micro-processing control module U3, a Bluetooth communication module U2 and a wireless communication module U5; the pre-valve temperature and pressure sensor S2 is arranged at the front end of a steam drain valve of the steam pipeline F1 and is connected with the digital-to-analog conversion module U1; the temperature sensor S1 behind the valve is arranged at the rear end of a steam drain valve of the steam pipeline F1 and is connected with the digital-analog conversion module U1; the digital-to-analog conversion module U1 is connected with the micro-processing control module U3, the micro-processing control module U3 is connected with the Bluetooth communication module U2 and the wireless communication module U5, and the battery U4 is used for supplying power to the system.
The digital-to-analog conversion module U1 is used as a core data conversion component and receives a first resistance signal and a second resistance signal sent from the pre-valve temperature and pressure sensor S2 and the post-valve temperature sensor S1. The two resistance signals respectively reflect the temperature and pressure conditions of the steam trap valve, and are key parameters for monitoring the state of the whole system. After receiving these resistance signals, the digital-to-analog conversion module U1 first converts the analog resistance signals into digital data. This is achieved by high precision analog to digital conversion techniques, ensuring that the converted data signal retains all the critical information of the original signal and can be easily interpreted and processed by the microprocessor control module U3. When the microprocessor control module U3 receives the data signal converted by U1, it starts a series of data processing. First, it will calibrate and linearize the data by a preset algorithm to eliminate any possible bias and noise. The U3 module then compares the calibrated data to a predetermined threshold to determine if the system is in normal operation. The microprocessor control module U3 may respond quickly once it detects that the data is outside of normal range. For example, it may send an alarm signal immediately to an operator or directly adjust the operating state of the steam trap valve to ensure safety.
At the same time, the microprocessor control module U3 also supports interaction with other communication modules. For example, it may send data to the field engineer's mobile device for real-time monitoring via the Bluetooth communication module U2. Or the key data and the system state report are sent to a remote control center or a cloud server through a wireless communication module U5, so that remote monitoring and management are realized. In addition, the U3 module also supports a data storage function. It may store key data periodically in internal memory for future data analysis and fault diagnosis. In general, through the wireless monitoring of the system, plant managers and engineers can monitor the working state of the steam drain valve more easily and efficiently, ensure the stable operation of the system, respond to any potential problems or faults rapidly, and greatly improve the production efficiency and the operation safety of the system.
In some embodiments of the present application, the digital-to-analog conversion module is an ADC chip. The digital-to-analog conversion module is a core component in a digital system, and has the main task of converting an analog signal into a digital signal, so that the digital-to-analog conversion module is convenient for a microprocessor or other digital systems to process. The ADC chip has high precision and high stability and can adapt to various application scenes. The ADC chip in the present system needs to process two main analog signals: a resistive signal and a millivolt signal. Wherein:
Resistance signal: this is produced by a platinum resistance temperature sensor (e.g., PT100 or PT 1000) whose law of change is linear, i.e., the change in temperature is proportional to the change in resistance. But the microprocessor control module is not able to directly read or process the resistance signal and therefore needs to convert it into a digital signal.
Millivolt signal: this is generated by a diffused silicon pressure sensor. When the pressure changes, the sensor generates a millivolt signal that is linearly related thereto. Similarly, this analog signal also needs to be converted to digital form for subsequent processing.
The ADC chip periodically samples the input analog signal and converts each sampled value to digital form. This "periodicity" may be a very short time interval, such as microseconds or milliseconds. The result of the conversion is a series of digital values that represent the amplitude of the analog signal at different points in time. To ensure conversion accuracy, there is a reference voltage inside the ADC chip. All analog inputs will be compared to this reference voltage and the corresponding digital output value determined therefrom.
In some embodiments of the present application, the wireless communication module employs 4G or 5G technology. The data of the wireless steam drain valve parameter monitoring system can be transmitted in real time through a 4G or 5G wireless communication technology, and stable work in a complex industrial environment can be ensured.

The platinum resistance temperature sensing unit can realize temperature measurement error + -0.2 ℃, and the diffused silicon pressure sensing unit has the characteristics of high precision and good reliability.

In some embodiments of the present application, the platinum resistance temperature sensing unit is a PT100 platinum resistance sensor or a PT1000 platinum resistance sensor, and other types of platinum resistance sensors may be used in addition to PT100/PT 1000.
In some embodiments of the present application, the model of the micro-processing control module is STM32L071 chip or MSP430 chip.
In some embodiments of the application, the system further comprises: and the terminal equipment is connected with the Bluetooth communication module. Terminal devices (e.g., cell phones, tablets, hand-held terminals, or other mobile devices) are often used as interfaces for controlling, configuring, or monitoring remote systems and devices. These terminal devices can easily communicate wirelessly with various hardware components using bluetooth technology. The terminal equipment can display the working state of the system in real time, such as the key parameters of temperature, pressure and the like, so that a worker can quickly know the running condition of the system.

The server module provides the system with the ability to centralize all data of the storage device, making data backup, retrieval, and analysis more efficient. By means of the server, authorized users can access the system data remotely from anywhere in the world, enabling cross-regional device management and monitoring. Servers typically have more computational power and can be used to perform complex data analysis, pattern recognition and prediction to provide decision support for future maintenance and operations. The server can be used as a centralized integration point of a plurality of devices to realize data synchronization and integration of the devices, and when the system detects an abnormality or reaches a preset warning threshold value, the server can automatically send an alarm or a notification to related personnel to ensure quick response and processing.
