Public places is an important part of human society, improve and enhance the quality of environmental health in public places is directly related to the people's health, therefore, looking for a set of monitoring, supervision as one of the automated management system of public places health is imperative. Convenient beach cleaning car, the public places of health management system combined with the characteristics of public places of health, the entire automated management system consists of three major components, namely, in the health supervision department of the central processing and control institutions, working in the public places of the site of the extension of the measurement and control institutions and communication networks. As the extension is working in different areas, environments, locations, distance of intelligent measurement and control equipment, which raises the issue of computer communication networks, and computer communication is inseparable from the communication line (channel), but the health supervision department to establish their own dedicated communication network in the area under their jurisdiction, whether economically or technically speaking is unrealistic, therefore, the use of ready-made public network (post and telecommunications network) As the relay transmission equipment is the best choice. This not only can greatly reduce the construction of automated management system cost investment, but also has the equipment (relay transmission equipment) technical maintenance of the security and reliability of the public places of health automated management system, the host computer (IBM PC) is the core part of the whole system, but also the whole system of control and management centre. It is not only responsible for all the management work of the health supervision department, but also responsible for the task of controlling other extensions, as well as the supervision centre of all places and the processing, analysis and management centre of supervision data.

Due to the IBM PC's data processing and management affairs of the workload is very large, and bear the task of communication with all the extensions at any time, which produces a great contradiction between the two, the front-end machine is precisely for the solution of this contradiction and set up, that is, the front-end machine share part of the IBM PC's workload, that is, to ensure that the computer has enough time to deal with their own affairs, so that the whole system works in a reliable and good state. And the main role of MODEM is to achieve long-distance multi-computer communication; the role of automatic transfer switch is to achieve the dual role of telephone communication and computer communication on leased trunk lines to improve the utilisation rate of the trunk lines. The extension is an intelligent measurement and control equipment integrating on-site hygiene index testing, hygiene index exceeding automatic alarm, communication and computer clock display. When there are health indicators exceeding the standard, automatic timing or real-time start the alarm, so that it sends out on behalf of the corresponding health indicators exceeding the standard of audible or visible signals, to remind the place on-site management personnel to identify the causes in a timely manner and make improvements, and at the same time, the MCS-51 will be the data sent to the central processing and control institutions, the alarm until the health indicators are qualified or up to the standard.

CPU and peripherals or computer information exchange (communication), there are two ways to query and interrupt, according to the health management requirements of public places and the characteristics of the system composition, should choose to interrupt the way, which not only improves the efficiency of the CPU and to ensure that the host has enough time to deal with the management of the affairs, but also has a relatively good performance of real-time response. Extension programme design, in addition to follow the above basic principles, the main consideration of the real-time response rate, that is, the use of assembly language, this is because once the extension of the field test, there is no need to be as complex as the host as often as the transaction operations. In the extension for some daily and necessary business operations, in general, is relatively simple, which as long as the reasonable settings of the corresponding transaction processing of special function keys to achieve the same purpose.
