Application of paperless recorder in temperature and humidity measurement and control of food cold storage

Description of temperature and humidity measurement and control project of food cold storage:

The on-site signal is connected to TP710 true color 16-channel paperless recorder. The data and records of the on-site signal displayed by the paperless recorder are saved (power failure data is never lost), and connected to the computer through RS485 data interface (communication converter). The computer software (Kingview) collects the data of the on-site recorder, and displays the working condition data, curves and alarm prompts on the computer screen.

The temperature and humidity signals of eight food cold storages are respectively connected to two TP710 true color paperless recorders, and the alarm values of high temperature, low temperature, high humidity and low humidity can be set freely for each temperature and humidity. The alarm output is connected to the flash buzzer, and when the alarm value reaches, the relay outputs an alarm current to the flash buzzer, and the equipment operator is reminded in time when the flash buzzer lights up and gives an alarm.

Introduction of computer monitoring software

1. The built-in RS485 or RS232 communication interface of two paperless recorders is directly connected with the computer in the central control room, and the background monitoring screen simulates the working conditions of food cold storage and displays the field data in a centralized way (the pictures are for reference only, subject to the actual picture).

2. Curve interface, which shows the trend chart of temperature and humidity curves at various points on site. After being equipped with a printer, the curve can be printed and kept.

3, data viewing, you can browse past data, you can export it to an excel spreadsheet.

Brief introduction to the function of topree TP710 true color paperless recorder

1. Overview display: 16 channels of temperature and humidity are displayed on the same screen, and the temperature, humidity and alarm status are displayed in real time.

2. Trend display page, curve and bar chart. The color of the curve or bar graph can be modified.

3. Extra-large digital display, which displays the measured values of single channel and displays them in large font.

4. Historical curve, which is convenient for viewing the previously recorded data on site (the length of data recording is related to instrument setting).

The temperature and humidity of eight food cold storage (32 roads) are connected to two true-color paperless recorders TP710, so that the data for on-site display, recording and power-off can be protected from being lost, and the alarm prompt function of over-high temperature, over-low humidity and over-high humidity can be provided, so that the on-site staff can be prompted to turn on the equipment to heat up, cool down, humidify and reduce humidity in time, so as to strictly ensure the food quality, greatly reduce the generation of defective products and also provide information. TP710 True Color Paperless Recorder has a built-in communication interface, which can communicate directly with the control room computer or industrial computer, and display, view, store and print on the computer or industrial computer in real time. The monitoring personnel can directly monitor the temperature and humidity of the food cold storage in the office, and in the office, they can really know whether the field staff have done their duty and whether the products are unqualified.
