Doctor-patient emergency solution

2018-12-06

【Project Overview】
With the frequent occurrence of medical troubles, how to maintain the order of diagnosis and treatment has become an urgent problem. On December 20, 2013, 11 national ministries and commissions including the National Health and Family Planning Commission, the Central Comprehensive Administration Office, the Ministry of Public Security, and the Ministry of Justice jointly issued and issued the "Special Action Plan on Maintaining Medical Order to Combat Medical-related Illegal and Criminal Laws", and proposed the establishment of medical-patient emergency Emergency response plan for incidents, improve police-medicine linkage, joint prevention and control mechanisms, improve on-site handling capabilities for emergency emergencies, and severely crack down on medical and noisy behaviors.
The hospital has the characteristics of large total area and scattered distribution of various departments. Although there is a video surveillance system, due to the large number of internal video points, security personnel may be tired and omission to monitor the screen for a long time. Therefore, when an emergency occurs, a complete emergency alarm system is needed to enable the security center to receive information such as the location of the alarm person and the department in a timely manner. At the same time, it can interface with the hospital broadcast system and cooperate with the 110 command center to form a multi-directional Multifunctional hospital emergency alarm system platform.

【solution】
The hospital emergency solution launched by Tianjin Optoelectronics Anchen Information Technology Co., Ltd. uses China Mobile's wifi base station to form a wireless network, combined with RF wireless transmission of location positioning information. When a doctor-patient event occurs, the medical staff can quickly and easily trigger the alarm signal through the card-type mobile alarm to transmit the location and personal information to the alarm center. The alarm information will be displayed on the large screen of the security center, ensuring that the hospital will deploy security personnel as soon as possible, and at the same time, it can quickly communicate 110 to arrange the patrol police to arrive at the scene for processing.

【Core functions】
WIFI network:
The receiving distance of common wireless alarms is limited, and it does not meet the requirements of large-scale emergency alarm fortification in hospitals. Many similar products on the market, in order to increase the transmission and reception distance, blindly increase the transmission power or increase the receiving antenna, causing radio standards to be exceeded, or causing interference to medical equipment, increasing hidden dangers.
The wireless network formed by our company using WIFI base stations complies with the standards of the National Radio Regulatory Commission. It is safe to use and covers a wide area, which fully meets the needs of wireless emergency alarm systems in hospitals.
Two-way communication
At present, the commonly used wireless alarms are generally controlled by a remote control. This one-way communication method is susceptible to interference by external factors and often produces false alarms and false alarms, which greatly reduces the reliability of the alarm system. In addition, when a unidirectional communication alarm device encounters two alarm devices at the same time, the host cannot recognize it because of interference.
Based on the two-way communication function of China Mobile's wifi base station, our company has completely solved this technical difficulty and realized two-way communication.
Mobile positioning
The use of wireless positioning engine technology solves the problem of alarm positioning during sports such as doctors' rounds.

3.Wireless relay router
  • Within the effective receiving range of wireless alarm equipment and wireless network server, no repeater is needed (wide straight distance of 2 kilometers);
  • Alarm devices that exceed the effective receiving range will form a network with the closest repeater in the wireless network, link routing and server communication;
  • The relay router has the function of automatically establishing a data link and automatic link repair. Once a data link is not smooth, the device can automatically find another link until it is connected to the server;
  • The relay router acts as a reference node for positioning reception in the mobile positioning alarm, obtains the position of the mobile button through the Receive Strength Indication (RSSI) algorithm, and sends the position data of the mobile button to the server;
  • The 2.4 GHz frequency band is used, and its design architecture complies with the IEEE 802.15.4 protocol and ZigBee protocol, which belongs to a license-free frequency band
  • Receive sensitivity <-92 dBm, transmit power is adjustable from 7-20 dBm;
  • Has 0 ~ 15 (total 16) optional working channels
  • Total number of relay router points: 4294967295 nodes;
  • Total network number (network ID): 65535 groups
  • The communication method is two-way, with a full handshake function. If any problem occurs in the middle, it will be repeated.
4.Wireless centralized controller
  • Coordinate the establishment and cancellation of the entire wireless alarm network, alarm control, data transmission, and interface with the hospital HIS gateway;
  • The 2.4 GHz frequency band is used, and its design architecture complies with the IEEE 802.15.4 protocol and ZigBee protocol, which belongs to a license-free frequency band
  • The receiving sensitivity is -92 dBm, and the transmitting power is adjustable from 7-20 dBm;
  • Has 0 ~ 15 (total 16) optional working channels;
  • Total number of network nodes (alarm terminals): 4294967295 nodes;
  • Total network number (network ID): 65535 groups;
  • Each hospital has a different network number (network ID), and the two overlapping networks will not affect each other;
