The reason why textile factories need to install temperature and humidity monitoring systems is:

1. Water must be added regularly and cannot be used in environments below zero degrees
2. Personnel must conduct regular patrols to check, and there may be inconsistencies in meter readings among different individuals The personnel focused some of their energy on meter reading, but not all of their energy on regulating the relevant equipment of the air conditioning
There is a large temperature difference between indoor and outdoor during winter, so checking the outdoor dry and wet bulb temperature requires going outdoors. However, in northern areas, outdoor temperatures are generally below zero degrees in winter, while textile factories usually have indoor temperatures of over 20 degrees. The temperature difference between indoor and outdoor is large, making it inconvenient to check outdoor readings
There are many fraudulent practices, and management personnel usually check how many times the table has been copied and whether the readings are within the range. However, the data on the table is manually filled in, resulting in data that is not very real-time and accurate
A dry wet bulb thermometer costs about 100 yuan, and a spinning mill with 50000 spindles requires about 24 pieces, totaling 2400 yuan If a person reads a meter (both inside and outside) for about 20 minutes, a shift reads 8 times, a total of about 480 minutes per day, and the working time of about one person plus the salary of the staff, it wastes about tens of thousands of yuan per year. However, if a spinning mill with 50000 spindles adds a temperature and humidity monitoring system, it increases by about tens of thousands of yuan If personnel focus their energy on how to adjust air conditioning equipment, it is estimated that the intangible benefits of increasing production, improving quality, reducing waste and yarn recycling will increase by about 100000 yuan per year due to appropriate air humidity and temperature. Therefore, a temperature and humidity monitoring system for textile factory workshops is necessary

Detailed explanation of temperature and humidity monitoring system in textile factory workshop:

The intelligent humidity monitoring system for textile machinery is a core technology developed by Beijing Jiuchunjian with independent intellectual property rights. Based on the special requirements for temperature and humidity in the fabric processing technology of the textile and printing and dyeing industries, experienced engineers in textile and printing and dyeing processes have been organized to conduct extensive on-site experiments and develop an automatic humidity control system for textile machinery. After years of market testing, the intelligent humidity monitoring system for textile machinery has been successfully applied in processes such as drying of yarn spindles, drying and washing after printing and dyeing, and high-temperature drying and shaping in textile machinery. The intelligent humidity monitoring system for textile machinery has taken special measures for humidity measurement sensors, intelligent monitoring and adjustment instruments and other system components, enabling it to operate stably in special environments such as high temperature, high humidity, high electromagnetic interference, and high electrostatic interference in the textile and printing and dyeing industries. The product has been widely recognized and promoted by customers.

The temperature and humidity monitoring system of Beijing Jiuchunjian Technology mainly installs temperature and humidity sensors at reasonable locations in textile factories to achieve 24-hour real-time monitoring of temperature and humidity, and can display real-time temperature and humidity measurement values at various locations on the monitoring host in the central control room. Once the value exceeds the preset upper and lower limits of temperature and humidity, an alarm can be triggered on the monitoring host by changing the color of the corresponding position value. To monitor the temperature and humidity conditions of the entire textile factory as a whole, temperature and humidity transmitters can be installed at the inlet of the fresh air fan and the return outlet of the main air conditioning unit to detect temperature and humidity.

The temperature and humidity sensor converts the temperature and humidity values detected on site into digital signals through a conversion circuit and transmits them to the acquisition box. After conversion by the acquisition box, it becomes a standard RS-485 communication protocol and is transmitted to the backend management computer. The computer software manages and centrally displays, controls, prints, stores and other functions

Composition of temperature and humidity monitoring system:

The system consists of four parts: temperature and humidity sensors, digital transmitters (with LCD display), communication buses (relays), and an upper computer.
1. Temperature and humidity sensor: responsible for detecting various temperature and humidity data.
2. Digital transmitter: responsible for collecting data from various temperature and humidity sensors, performing data calibration and conversion, displaying on site LCD (optional), receiving communication instructions from the upper computer, and transmitting data to it.
3. Communication bus (repeater): responsible for wired transmission of data and can extend communication distance.
4. Upper computer: Read the temperature and humidity data of the transmitter, display and record it, and perform various management functions.

Functions of temperature and humidity monitoring system:

1. The product adopts LCD display, with low power consumption and long lifespan.
2. Real time temperature data collection, with an interval of up to ms and fast response.
3. The interface is friendly, the operation process is simple and intuitive, and users can operate it after simple training.
4. Simultaneously display temperature and humidity data online.
5. Simple configuration method: only set the correspondence between measurement points and test addresses, as well as the correction values for measurement points.
6. Real time display of monitoring values for each monitoring point in graphical or curved form.
7. Built in buzzer alarm function, users can set the upper and lower limits and alarm values of each monitoring point according to the actual situation.
8. Through sound, light SMS、 Method over limit alarm.
9. Can track and record changes in environmental temperature and humidity throughout the entire process.
10. High stability and 24-hour uninterrupted operation, it is a new product that replaces traditional temperature and humidity transmitters.

Advantages of temperature and humidity monitoring system:

1. The operation interface is graphical, the operation process is simple and intuitive, and users only need to undergo simple training to operate it;
2. Provide functions such as trend curves, data reports, and over limit alarms, which can be expanded according to application requirements;
3. Due to the use of advanced digital temperature and humidity sensors, this solution is wired according to the RS-485/422 communication network, which is convenient and economical. Only one pair of twisted pair cables can connect 32 acquisition terminals, greatly reducing the amount of wiring work, and because it is a digital signal, there will be no transmission error or signal loss.
4. The system is designed specifically for environmental monitoring and has the functions of on-site touch screen display and over limit alarm. It can also be connected to the monitoring department's computer for real-time detection and recording
