Problems solved by technology
There are also some temperature and humidity monitoring design schemes in other fields, but they cannot meet the environmental monitoring requirements of pharmacies
Therefore, most hospitals still use manual regular inspections to monitor temperature and humidity. This method of manual regular inspections consumes a lot of manpower and material resources, and sometimes it is impossible to find environmental abnormalities in time during the inspections, which may easily lead to loss of drug efficacy. Major accidents such as fires have affected the later sales and use of drugs and brought a lot of unnecessary losses

The invention discloses a medicine warehouse environment monitoring system based on Zigbee wireless communication. The medicine warehouse environment monitoring system comprises a plurality of environment monitoring nodes and an environment monitoring host. Each environment monitoring node comprises a single-chip microcomputer integrated internally with an A / D converter, and a node Zigbee wireless communication module. The input end of each single-chip microcomputer is connected with a temperature and humidity sensor, and the input end of each A / D converter is connected with a signal conditioning circuit module. The input end of each signal conditioning circuit module is connected with a dust sensor and a smoke sensor. The environment monitoring host is composed of an ARM micro-controller, a host Zigbee wireless communication module and an Ethernet communication circuit module. The input end of the ARM micro-controller is connected with a key operation circuit module. The output end of the ARM micro-controller is connected with a liquid crystal display screen and an acousto-optic alarm drive circuit module. The invention can detect not only the temperature and the humidity inside a medicine warehouse, but also the dust and smoke in the medicine warehouse.
Description
technical field [0001] The invention belongs to the technical field of drug warehouse environment monitoring, in particular to a drug warehouse environment monitoring system based on ZigBee wireless communication. Background technique [0002] Drug warehouse is an important part of drug distribution management in medical institutions. The poor environment of the drug store directly affects the quality of drugs and then affects the clinical treatment effect. In order to ensure the safety and effectiveness of medication for patients, it is necessary to strengthen the monitoring of the drug store environment. The pharmaceutical GSP system standard points out that temperature and humidity are the key factors affecting the quality assurance of pharmaceuticals. Especially in the preservation of Chinese herbal medicines, temperature and humidity almost play a decisive role. Many local food and drug administrations have also noticed this problem, and have made clear requirements ...
