The bed pressure data monitoring system of Taizhou Welfare Institute uses wireless products such as Xinli Technology’s related wireless data acquisition devices, wireless management devices, and wireless pressure sensors to monitor the real-time status of the elderly in the orphanage, and keep abreast of the elderly’s activities at night to avoid An unexpected situation occurred.

The following is an overview of the bed pressure data monitoring system of Taizhou Welfare Institute:

1. Project background

The social welfare institution is a place for adopters who are responsible for abandoned babies in society and urban “three noes” objects (incapable of working, no source of income, and indeterminate supporters or supporters). It plays an active role in safeguarding my country’s human rights, stabilizing social order, and serving economic construction. The safety guarantee and effective management of the orphanage are the basic prerequisites for the normal operation of the orphanage.

2. Project requirements

The system requires real-time monitoring of the pressure signals and bed alarm signals of the 324 beds in the five floors of the entire welfare institution. The data transmission method is wireless transmission. The system should be convenient for the second phase of extended applications (internal temperature and humidity monitoring of the room, air-conditioning operation) Status, elevator running status, etc.). The following functions need to be realized:

1. Using low-power wireless data transmission products, installation is simple and convenient, without damaging the existing building structure;

2. The bed sensor system is equipped with wireless pressure on the beds in the elderly roomsensor, It can monitor the information of whether the elderly is in the bed in real time. If the elderly leaves the bed during the alert time (such as 20:00 pm to 7:00 the next morning) for half an hour, the staff will be reminded by sound and light alarm methods to ensure that the elderly Safety and effective management during activities with children;

3. Digital monitoring and computer network management, friendly man-machine picture, and real-time display of monitoring point location and information by simulating on-site room state diagrams.

3. Scheme design

The monitoring system is a hierarchical distributed network structure, consisting of a device layer, a wireless network transmission layer, and a monitoring layer. The device layer is mainly composed of sensors and other control equipment; the wireless network transmission layer is mainly composed of wireless pressure sensors, wireless management devices, etc. Equipment composition; the monitoring layer is composed of main equipment such as computers, monitoring software and network switches.

Bed Configuration Table on Floor of Welfare Institute

1. There are 5 floors in total. As shown in the table, the 2nd and 3rd floors are super-large rooms, each with 4 rooms and a total of 78 beds. Each bed is equipped with 3~4 wireless pressure sensors, and each bed is at the same time Need to configure a signal amplifier to amplify the sensor’s micro signal to 4-20mA.

There are 28 rooms on each floor on the 2.4th, 5th and 6th floors. Each room has 2 beds. In the rooms on the 4th to 6th floors, each room has a WN60 wireless data acquisition device to collect sensor signals and alarms in the room. Equipment signal, one WN60 wireless data acquisition device can also be used in 2 rooms at the same time (1 WN60 wireless data acquisition device can collect 4 analog signals and 4 switching signals at the same time).

3. WN90 wireless management device configuration: 1 WN90 wireless management device can manage the data of 64 WN60 wireless data acquisition devices at the same time, so the entire system is configured with 2 sets.

4. The service desk of the entire floor is equipped with a set of monitoring computers, only one server needs to be configured as the host, and the monitoring platforms of other service desks and nursing rooms can be the client, and the client can also monitor the monitoring information in real time at the same time.

The schematic diagram of the system structure is as follows:
