2016 International Conference on Electronic Information Technology and Intellectualization (ICEITI 2016) ISBN: 978-1-60595-364-9 The Schematic Design of the Ward Temperature Regulation Based on Computer Remote Control Xiaotao Lai and Juan Zhong ABSTRACT In this paper, the current hospital ward temperature regulation mode is analyzed. On this basis, the scheme is designed. The paper introduces mainly the system design and the completion of the scheme. INTRODUCTION Along with the rising of our Chinese economic level year by year, people have higher demands for their food, clothing, shelter and medical service. In medical service, people demand not only the doctors' sophisticated medical technique, but also the good environment of hospital, especially the living conditions of the ward, such as temperature, humidity and so on. Due to different requirements for temperature of the different hospitals, different departments and different patients, the ward temperature is different. More often, many patients don't know what is the actual temperature of the ward and adjust the temperature optionally, which makes the ward temperature unsuitable. The present status of hospitals in our country is that patients are more, nurses are less. Therefore, when a nurse is busy with their work, they rarely pay attention to the temperature change of the wards, which leads to various complaints about room temperature. With the advent of technologies of computer remote control, the Xiaotao Lai, Juan Zhong, School of Gannan Medical University, Ganzhou, China 602
whole room temperature can be effectively regulated, and the situation has been controlled effectively, which reduces the nurses work, and is good to doctor-patient relationship. THE PRESENT STATUS OF THE WARD TEMPERATURE REGULATION IN OUR COUNTRY Many hospitals in our country are built in the nineties. Therefore, the wards were designed without considering the temperature regulation. Then, considering the needs of different patients, the hospitals equipped with air- conditioners in the wards to adjust the room temperature. But every room needs a remote control to turn on the air conditioner. In order to convenient management, the remote controls are managed unified by the nurses. However, a lot of inconvenience to patients and nurses are happened. The hospitals built in the recent period, the wards are basically installed central air-conditioners. The patients in the ward can adjust the indoor temperature by themselves through the control panels. In fact, because of no idea of the actual temperature of the wards, the patients more than often make the room temperature unsuitable when they adjust the temperature. Therefore, the nurses monitoring and management are needed.. Hospitals on ward temperature regulation need to spend a lot of manpower and material resources, and the result is bad. The existing management mode as shown in figure 1 Figure 1. There is a circle among ward temperature, the patient and the nurse. As long as an error happens in a link, a lot of problems will emerge. The Computer Remote Control System The computer remote control system is a system that controls the related equipment with the help of certain computer, communication equipment and the corresponding software. 603
With the rapid development of information technology, the related equipment of computer has been more and more, the price is cheaper and cheaper. Especially the emergence of a wireless network greatly improves the efficiency of communication equipment, which makes people's life more convenient. The computer remote control has experienced two stages. The two stages complement each other and develop commonly. One is a stage of cable network, which links physically the two devices by means of the network cable, twisted pair, and optical cable, then codes through certain a language program, so as to achieve the purpose of controlling. The other is a stage of wireless network, in which two devices butt joint through radio waves, then achieve the purpose of control through the programming software. These two stages have their own goodness and weakness. In the stage on cable a number of lines need to be laid. Therefore, it needs a lot cost in the line maintenance. Nevertheless, in the second stage of wireless, there is a higher demand for the signal of requirement. If the signal can t be received in some places, the remote control will not work. The Design of The Scheme Although the actual situation in each hospital is not the same, the schematic design and layout are similar. Mostly the hospitals achieve the goal of controlling through the combination of cable network and wireless network. Therefore, the principle must be followed is that the main equipment and the main line link through a cable network, and the terminal equipment and the branch joint through the wireless network, then make a unified software management, so as to achieve the goal of effective control. As shown in figure 2 In figure 2 the scheme consists of two parts. One is the hardware module, the other is the software module. In the hardware module, the main work is to set up a server and a workstation. The workstation shall be set up in accordance with the hospital departments. At present, many inpatient departments in our hospitals have basically finished the work. And each nurse station has been equipped with computers, cable servers and wireless servers. Because of signal strength problem of the wireless router, the wireless AP has to been installed in the inpatient corridor, the wireless temperature sensors and wireless temperature controllers must be installed inside the wards. In some wards that needs segregated from electromagnetic radiation, the installation of the cable temperature sensor and the cable temperature controller is necessary. In the software module is mainly divided into two big modules-monitoring module, and control module. In monitoring module, the main job is to set a temperature range through the temperature sensor. For example, the room temperature of pediatric ward can be divided into: the room temperature of neonatal chamber with 20 to 22 advisable, the room temperature of premature babies in which should be kept for 24 ~ 26, and the one of ICU treatment 604
which temperature ranges between 18 to 22, etc. At the same time, to set timing report data for temperature sensor is also the important job of monitoring module. When the temperature exceeds in the range, the temperature sensor will give an alarm signal to monitoring software. And the monitoring software will send the information to user terminal of the computer, mobile phone or a panel computer. The nurses can know the basic information through the software. In the control module, after knowing the information, the nurses can take control over the ward temperature through the software turn on or turn off the air-conditioners through the temperature controller, so as to achieve the purpose of regulating the ward temperature. And the nurses can go immediately to the wards to see whether there is a need to solve the problem. CONCLUSIONS Figure 2. At present in China, the doctor-patient relationship is the problem which all hospitals have to face with. Controlling and keeping regular records of the ward temperature through the computer remote controls not only can offer hospitalized 605
patients a comfortable living environment, which helps alleviate the illness of the patients, but also can lessen a lot of complaints from the patients, thus reduce the conflicts between doctors and patients.
