Drug warehouse temperature and humidity monitoring system solutions
First, development background
At present, the pharmaceutical industry is increasingly demanding the drug storage environment. The drug administration department has clearly requested that the drug warehouse needs historical environmental monitoring data, and it should be included in the certification assessment index. Because there are many points requiring monitoring, the traditional recorder is used. The method is not adaptable, so it is necessary to develop a multi-point, remote, and easy-to-install temperature and humidity monitoring and recording system.
Second, the system architecture
The scheme adopts a distributed intelligent network monitoring system. The monitored points can expand the types of hardware and increase the number of monitoring points as required. The monitoring terminal adopts a touch screen IPC can be embedded and installed on the site or can be placed in a dedicated monitoring room.
Based on the fieldbus-based transmission, digital transmitters are used to facilitate field wiring. The recording platform uses a PC or embedded touch screen to support data export and Ethernet transmission. The software interface is graphical, and commercial configuration software is proposed.
System composition:
The system consists of four parts: temperature and humidity sensor, digital transmitter (with LCD display), communication bus (repeater) and embedded touch screen and upper computer management software.
1, temperature and humidity sensor: responsible for detecting the temperature and humidity data.
2. Digital Transmitter: It is responsible for collecting the data collected by each temperature and humidity sensor, performing data correction conversion, performing on-site LCD display, accepting the communication command from the upper computer and transmitting the data to it.
3, communication bus (repeater): responsible for the data cable transmission, and can extend the communication distance.
4, touch screen and software part: responsible for the digital transmitter communication, read the transmitter temperature and humidity data, display, record, and perform various management functions.
Third, system function
1. The operation interface is graphical, the operation process is simple and intuitive, and the user only needs to operate with simple training;
2. The real-time measurement values ​​of each monitoring point are displayed in a table and a curve manner.
3. The historical data of each monitoring point is displayed in a table and a curve manner.
4. You can query data for any day, month, or year, and display and print in tables and graphs.
5. It can count the maximum, minimum and average data of any interval.
6. You can set the upper and lower alarm value of each monitoring point. And record the alarm value, you can query the alarm history
7. When the measured value exceeds the upper and lower alarm value, the alarm signal can be automatically sent to the mobile phone or email via the acousto-optic, automatic telephone voice alarm, and the alarm signal can be automatically sent to easily achieve unattended.
8. Data export function, U disk data export function
9. Web Edition features remote remote users
10. The operator must authorize to query historical data, perform data analysis, and print operations.
Fourth, technical parameters:
1. Number of monitoring points: 1 to 32 (expandable to 255);
2. Temperature range: -40°C～+60°C;
3. Temperature accuracy: ± 0.5 °C (-10 °C ~ +35 °C);
4. Humidity range: 0 to 100% RH
5. Humidity accuracy: ± 3% RH (30 to 90% RH)
6. 485 bus transmission distance: < 1200 M
7. Power: 220V/AC ±10%
V. System advantages:
1, the graphical user interface, the operation process is simple and intuitive, the user can only operate through simple training;
2. Provides 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, the program according to RS-485/422 communication network wiring, convenient and economical. Only one pair of twisted pairs can be used to connect 32 acquisition terminals, which greatly reduces the amount of wiring work and does not cause transmission errors or signal loss due to digital signals.
4. The system is specially designed for storing drug environment monitoring. It has the function of on-site touch screen display and over-limit alarm. At the same time, it can be connected to the monitoring department's computer for real-time detection and recording. The monitoring computer and the monitoring system can be connected via Ethernet. According to the customer's needs, the monitoring system of multiple reservoir areas can be networked. With one monitoring computer, the temperature and humidity monitoring of all storage areas can be completed and the management can be simplified.
Sixth, engineering basic functions and quotation
According to the actual distribution of a pharmaceutical company, the warehouse is 4 layers, and each layer is used as a unit (according to the above diagram). Each layer has 1 touch screen and 10 temperature and humidity recording transmitters (the quantity can be increased or decreased according to the actual distribution). Each floor can view the real-time temperature and humidity changes at any time, and can read the history of temperature and humidity conditions on the spot, temperature and humidity exceeding the standard (more detailed features visible). Connect 4 touch screens to the master control computer. Can achieve a full range of records, monitoring, early warning and other functions. Specific quotes are as follows:
