Description
Technical Field
The invention relates to the technical field of automatic monitoring, in particular to an automatic monitoring method for gene detection laboratory equipment.
Background
With the increasing popularity of computer applications, laboratory data management systems have also entered a rapid development phase. Particularly, when a gene detection experiment is performed, various environmental parameters are usually recorded and an experiment report is filled in, and the experiment report needs to be stored for a long time, so that whether the laboratory conditions are suitable for developing the current biological experiment is judged according to the information of the various environmental parameters. Various environmental parameters can also be adjusted using the environmental parameter adjusting device, for example, the temperature of a laboratory can be measured using the temperature measuring device, the humidity of the laboratory can be measured using the humidity measuring device, the ultraviolet light intensity of the laboratory can be measured using the ultraviolet light measuring device, then the temperature of the laboratory can be adjusted using the temperature parameter adjusting device, the humidity of the laboratory can be adjusted using the humidity parameter adjusting device, and the ultraviolet light intensity of the laboratory can be adjusted using the ultraviolet light parameter adjusting device. Various environmental parameter measurement devices are capable of providing various valuable reference data for various operations.
The existing laboratory data management system is generally designed based on the traditional experimental process and by adopting a C/S framework, so that the system cannot meet the correlation between the experimental link and the analysis link, and further cannot meet the function of automatically generating a detection report according to a second-generation sequencing result in gene detection. Moreover, the development of the system based on the C/S architecture focuses on the client software, but the existing large and small hospitals and clinics are in a large number, so the existing laboratory data management system needs to install a large number of client software, which may cause the following problems: firstly, the client software is high in installation difficulty and high in cost for the first time; secondly, the gene detection technology is rapidly developed at present, and the corresponding system is updated and updated quickly, so that the client software needs to be updated and upgraded frequently, which obviously needs higher time cost and economic cost. In addition, many information in the gene detection process needs to be managed in a unified way and even needs to be operated in a coordinated way, but the clients based on the C/S architecture are independent from each other, and data can be managed in a unified way only by synchronizing the data to the server, so that the information sharing degree of the laboratory management system based on the C/S architecture is not high, and the laboratory management system based on the C/S architecture is not convenient to manage in a unified way.
Meanwhile, the fault diagnosis is to analyze and judge according to the information obtained from the operation process of the instrument and equipment to determine whether the instrument and equipment have faults and cause the faults. Along with the development of science and technology, the degree of automation of the structure and the system of the existing instrument and equipment is more and more complicated, the possibility that the instrument and equipment breaks down is increased, meanwhile, the control and the detection of the faults of the instrument and equipment are more and more difficult, and the fault detection problem of the instrument and equipment is more and more emphasized by experimenters because the loss caused by the faults of the instrument and equipment is more and more large. However, because the existing instruments and equipment have high integration and complex structures, manual detection is generally needed during fault diagnosis, and diagnosis errors are easy to occur.
