In order to effectively respond to the epidemic, on February 4th, with the promotion of the Central Guidance Group, Wuhan comprehensively began to transform the exhibition center, stadiums, etc. into "square cabin hospitals" to centrally treat patients with mild pneumonia infected by new coronavirus. As of now, more than ten square-level hospitals have opened warehouses.
As the forefront of the epidemic, the Fangcai Hospital plays an important role. Although they are temporarily set up, the hospital's various facilities are very complete. In addition to the medical facilities, communications, power systems, security systems, etc. are also equipped, and strive to provide a more warm, comfortable and safe medical environment for doctors and patients.
Currently, as a security alarm company with a strong sense of social responsibility, Ai Li An has been actively taking action. The emergency help alarm system previously provided for the highly anticipated Raytheon Hospital provided reliable security for doctors and patients. During the construction of the Wuhan side cabin hospital, Elian once again assisted and provided emergency help alarm systems for multiple side cabin hospitals. In her field of expertise, Eleanor has contributed to winning the battle against the epidemic.
I. System requirements
At the beginning of the project design, the following requirements were made for the alarm system:
1. The equipment used in the alarm system must meet the requirements of national laws and regulations and the current compulsory standards, and pass the inspection or certification of legal institutions.
2. The emergency alarm device should be set to an irrevocable state, and there should be measures to prevent false triggering, and it should be self-locked when triggered.
3. When any of the following situations occur, the alarm control device shall issue an audible and optical alarm message, the alarm message shall be able to be maintained until manual reset, and the alarm signal shall not be lost:
a. In the fortified state, when someone touches the emergency alarm device, the alarm control device should display the address of the area where the alarm occurred;
b. In the fortified state, when multiple alarm buttons alarm at the same time, the alarm control device should sequentially display the area or address where the alarm occurred;
c. After the alarm occurs, the alarm should be reset manually and should not be reset automatically.
4. The design of anti-damage and fault alarm functions should meet the following requirements:
When any of the following situations occur, the audible and optical alarm information shall be issued on the alarm control device, the alarm information shall be able to be maintained until manual reset, and the alarm signal shall not be lost.
a. In the wired transmission alarm system, when the alarm signal transmission line is disconnected or shorted.
b. In a wired transmission system, when the detector power cord is cut off.
c. When the alarm controller main power / backup power fails.
d. In the system that uses the public network to transmit the alarm signal, when the network transmission fails or the information is continuously blocked for more than 30s.
2. Design of demand points
Medical Staff Needs
Install emergency alarm devices in the daily office of medical personnel. When medical personnel have an unexpected situation, they can quickly alert the monitoring center to the monitoring center through the alarm device and get help from security personnel in time;
Hospital key location needs
The emergency button is installed in the bathroom and other important locations. When an emergency occurs, you can press the emergency button to call the monitoring center and get help from security personnel in time;
Three. Specific design and principle
According to the project requirements, Ai Li An mainly made the following designs: The system is mainly composed of a front-end emergency help alarm button, an alarm host, an audible and visual alarm, and a linkage device. Manual alarm buttons are set at the nurses' station, doctor's office, nurse's office, and triage registration desk, and an alarm zone module is set in the weak current room.
In the specific system operation, when someone presses the emergency alarm button, the alarm is triggered, and the on-site sound and light alarm is driven. The alarm signal is uploaded to the back-end alarm control host through the defense zone address module. The back-end control system receives the alarm signal. At this time, the alarm system of the duty center immediately alarms to remind the staff on duty, and displays the alarm area through the LCD Chinese keyboard display, or the electronic map display of the alarm management software. Take measures according to the actual situation.
4. System advantages
Simple operation: just press the button to realize the alarm, more simple and convenient;
Stable signal acquisition and transmission: The system uses bus communication for transmission, and the operation is more stable;
The police information is more accurate: the system uses the LCD Chinese keyboard to display the alarm area, and the Chinese characters of the defense area can be arbitrarily changed. The defense area supports 7 Chinese characters to display the alarm position.
