Problems solved by technology

[0002] At present, in many welfare homes and hospitals in China, some accidents often occur in the care of bedridden elderly and patients with limited mobility. Patients leave the bed without the presence of nursing staff, resulting in accidents such as falls and falls. , especially when going to the bathroom at night, short-term nursing staff cannot know after falling down, which leads to accidents. Welfare homes, hospitals, and other fields currently do not have suitable technical solutions to deal with the above-mentioned accidents urgently

Embodiment 1

[0021] Such as Figure 1~Figure 3 As shown: when in use, place the pressure sensing element 14 on the elastic body 12, and then install the pressure receiving body 16 on the elastic body 12, and a strain chamber 15 is provided between the pressure receiving body 16 and the pressure sensing element 14; Then the housing 9 is fixedly installed on the elastic body 12 to form the bed pressure sensor 1 . Install the bed pressure sensor 1 at the bottom of the four bed feet of the bed. The output wire 10 of the bed pressure sensor 1 is connected to the signal acquisition and processing module 2, and the ADC conversion module of the signal acquisition and processing module 2 uses 10-bit sampling rate to carry out bed weight signal acquisition to the bed pressure sensor 1; The resolution is 1023 divisions, the maximum weight on the bed is set to 250 kg, (including the weight of the bed itself) the weight division value output by the single-chip microcomputer is approximately equal to 0...

Embodiment 2

[0024] Such as Figure 1~Figure 3As shown: when in use, place the pressure sensing element 14 on the elastic body 12, and then install the pressure receiving body 16 on the elastic body 12, and a strain chamber 15 is provided between the pressure receiving body 16 and the pressure sensing element 14; Then the housing 9 is fixedly installed on the elastic body 12 to form the bed pressure sensor 1 . Install the bed pressure sensor 1 at the bottom of the four bed feet of the bed. The bed pressure sensor 1 is connected to the signal acquisition and processing module 2, and the ADC conversion module of the signal acquisition and processing module 2 uses a 16-bit sampling rate to collect, so that the resolution of the weight change on the bed is 65535 divisions, and the maximum weight on the bed is set to 250 kg, (including the weight of the bed itself) the weight division value output by the single-chip microcomputer is approximately equal to 3.8 grams. During work, the signal ac...

Abstract

The invention relates to an Internet of things (IOT)-based bed wireless sensing device, which comprises a bed pressure sensor for detecting bed weight, wherein the output end of the bed pressure sensor is connected with a signal acquisition and processing module, and the signal acquisition and processing module acquires and processes the bed weight signal detected by the bed pressure sensor and then wirelessly transmits the processed signal to a bed management device of the IOT; and when the bed weight signal detected by the bed pressure sensor is lower than a set weight range and exceeds a set time length, the bed management device of the IOT outputs a bed alarm signal. When the bed weight information input to the bed management device of the IOT is lower than the set range for long time, the bed management device of the IOT outputs the alarm signal so as to avoid unmanned supervision when a person on the bed leaves for long time and an accident happens, improve the monitoring operability and improve the bed monitoring reliability; and the device has simple structure and is convenient to install and use.

Description

technical field [0001] The present invention relates to a bed position wireless sensing device, especially a bed position wireless sensing device based on the Internet of Things, specifically a bed position monitoring and management device based on the Internet of Things, belonging to the technical field of the Internet of Things. Background technique [0002] At present, in many welfare homes and hospitals in China, some accidents often occur in the care of bedridden elderly and patients with limited mobility. Patients leave the bed without the presence of nursing staff, resulting in accidents such as falls and falls. , especially when going to the bathroom at night, the short-term nursing staff cannot know after falling down, which leads to accidents. For this reason, welfare homes, hospitals and other fields currently do not have suitable technical solutions to deal with the above-mentioned accidents urgently. Contents of the invention [0003] The purpose of the presen...
