In order to ensure the quality of medicines in production, warehousing, distribution, and operation, and to ensure the quality of medicines and the safety of medicines, the pharmaceutical industry has become increasingly demanding on the drug storage environment. The pharmaceutical supervisory department has clearly required a history of medicine warehouses. Environmental monitoring data to ensure that the drug storage environment is in line with drug storage regulations. The requirements for temperature and humidity of drug storage are as follows: The drug store should be set with different temperature and humidity conditions. The cold storage temperature should reach 2 to 10°C; the cool storage temperature should not exceed 20°C; the normal temperature storage temperature should be 0 to 30°C; and the relative humidity of each warehouse should be kept between 45 to 75% RH.
To achieve comprehensive temperature and humidity monitoring, traditional manual recording is far from meeting requirements. Currently, advanced sensor measurement technology, digital communication technology, computer network technology, and automatic control technology are used to measure temperature and humidity as a measurement terminal, combining data acquisition. Instruments, controllers, etc., are used to form a temperature and humidity monitoring system specifically for pharmaceuticals, which enables effective monitoring and management of pharmaceuticals in all aspects.
The system temperature and humidity collection using RS485N temperature and humidity transmitter, the transmitter using Switzerland Shengn Ryan temperature and humidity probe, with self-calibration, high precision. Measuring parameters such as relative humidity, temperature, and dew point for pharmaceuticals, foods, etc. Warehouse and vaccine production environment. The design of an important room temperature and humidity intelligent monitoring system. Use industry standard RS485 communication format networking or wireless networking.
Option One
1, system composition
Option II
1, system composition
Remarks: This scheme is applicable to the situation where there are many temperature and humidity monitoring points without air conditioning control.
third solution
1, system composition
Remarks: This solution is suitable for situations where there are few temperature and humidity monitoring points and no air conditioning control.
Through the above scheme, the hardware structure is very simple, and the temperature and humidity sensor of an Ethernet interface can completely realize the collection and transmission of the temperature and humidity of the on-site environment. Field wiring is simple and easy to maintain. The temperature and humidity data are transmitted via Ethernet. We can monitor the temperature and humidity of the warehouse anywhere in the LAN or WAN and keep abreast of the environmental changes in the warehouse to ensure the security of warehouse items. The company's medical warehouse temperature and humidity monitoring system is very suitable for monitoring and monitoring of drug library environment, drug production, drug management and circulation and other aspects of temperature and humidity monitoring, but also very conducive to the smooth progress of GMP, GSP certification. At present, the system is widely used in pharmaceutical production, operating companies and drug regulatory departments, and has been recognized and welcomed by users.
