The night out-of-bed alarm can be set to alarm only if the important attention object gets out of bed or alarm when all criminals get out of bed according to the requirement. Wherein the important focusing object and the service management platform realize automatic data synchronization; frequent bed exit cues: when criminals frequently rise in a set period of time and reach a certain number, the system automatically sends out alarm prompts and pops up monitoring videos of the monitoring room for the police to check. The time period length and the number of times of lifting can be uniformly set; prompting the people who do not fall asleep for a long time: when the criminals still fail to fall asleep within a set time, the system automatically sends out prompt information. After the police clicks the prompt, the system invokes the monitoring video of the room where the criminals are in for the police to check; simultaneous bed leaving prompt for multiple people: when more than two criminals leave the bed simultaneously or in a very short time, the system automatically sends out prompt information. After clicking the prompt information, the system invokes a monitoring video of the monitoring room of the criminal for the police to check; low electricity suggests: because the intelligent mattress used by the system is powered by the built-in battery, the condition of low electric quantity needs to be prompted, so that the battery is replaced as soon as possible by a policeman. The intelligent bed can actively detect the electric quantity of the battery, and when the electric quantity is low, the intelligent bed actively sends out low-electric quantity alarm information; data connection failure prompting: the intelligent bed uses wireless mode to upload status data and alarm information. The system can automatically monitor the data communication state among the devices, such as the immediate prompt of the device failure system; alarm when leaving bed overtime: when the criminals leave the bed for a certain time and have no rest on the bed, the system automatically sends out an alarm prompt and pops up the monitoring video of the monitoring room for the police to check. The bed leaving timeout time can be uniformly set; heartbeat and respiratory mutation alarm: when a criminal's heartbeat or breath suddenly becomes faster or slower and the data continues to exceed the average heart rate and respiratory value range of the person. The system automatically gives an alarm and pops up a monitoring video of the monitoring room for the police to check; and (5) opening an alarm by the equipment: when the criminal opens the equipment, the intelligent bed immediately sends out an alarm signal, and the system linkage monitoring system pops up the monitoring video of the monitoring room for the police to check.
Referring to fig. 3-4, a deformation film 6 is installed between a mattress body 11 and a spacer 14, the lower end of the mattress body 11 is connected with a plurality of uniformly distributed pressing rods 7, the pressing rods 7 are in contact with the deformation film 6, gravity migration balls 8 are arranged on the upper side of the deformation film 6, a plurality of uniformly distributed magnetic balls 5 are installed at the lower end of a sensor module 13, a criminal can press the mattress body 11 to sink downwards under the action of gravity when sleeping on the mattress body 11, so that the deformation film 6 is synchronously pressed by the pressing rods 7, the gravity migration balls 8 actively roll to the sink under the action of gravity after the deformation film 6 is sunk, and then the sensor module 13 is actively moved to the sink through the magnetic attraction effect of the magnetic balls 5, so that the detection is directly corresponding to the criminal, and the distance is short, the interference is less, and the precision is high.
Referring to fig. 5-6, the gravity migration ball 8 includes a hollow ceramic ball 81, a plurality of stability augmentation bands 82 and a magnetic base liquid 83, the stability augmentation bands 82 are uniformly embedded on the outer surface of the hollow ceramic ball 81, a plurality of communication holes corresponding to the stability augmentation bands 82 are formed in the hollow ceramic ball 81, the magnetic base liquid 83 is filled inside the hollow ceramic ball 81, and the magnetic base liquid 83 partially enters the communication holes to compress the stability augmentation bands 82 during filling, so that a certain friction resistance exists between the gravity migration ball 8 and the deformation membrane 6, the gravity migration ball 8 is prevented from generating displacement due to normal slight fluctuation, the stability of the gravity migration ball 8 in a certain controllable range is ensured, the gravity migration ball 8 is still displaced after the friction resistance received by the stability augmentation bands 82 is exceeded, the active compensation effect of the gravity migration ball 8 after being slightly inclined can be improved by utilizing the flowability of the magnetic base liquid 83, and the gravity migration ball 8 is not easy to directly generate displacement.
The stability augmentation belt 82 is made of elastic friction materials, the maximum angle of the vertical section of the stability augmentation belt 82 corresponding to the hollow ceramic balls 81 is 5-10 degrees, the gravity migration balls 8 are not easy to displace within the range of 5-10 degrees of inclination of the gravity migration balls 8, so that stability within a certain controllable range is improved, the gravity migration balls 8 still displace after the inclination angle exceeds 5-10 degrees, the angle is not suitable to be too large or too small, the displacement action response of the gravity migration balls 8 is not accurate enough due to too large angle, and slight fluctuation is easy to occur due to too small angle.
The magnetic base liquid 83 adopts the mass ratio of 1:1 and non-newton liquid, and the filling percentage of the magnetic base liquid 83 is 80-90%, the magnetic powder is used for giving magnetism, and can attract the magnetic ball 5, and the viscosity coefficient of the non-newton liquid is larger, so when the non-newton liquid inclines for a certain angle, the non-newton liquid cannot immediately flow to compensate, and the gravity migration ball 8 can immediately displace after the gravity center deviation is overlarge.
The deformation film 6 is also filled with deionized water, the filling height of the deionized water accounts for 1/5-1/4 of the diameter of the gravity migration ball 8, under the normal state, the deionized water can utilize the buoyancy effect to reduce friction resistance and noise when the gravity migration ball 8 is displaced, and can flow to the concave part along with the gravity migration ball 8, the height of the deionized water at the concave part can be increased, so that when controllable fluctuation occurs, the stability of the gravity migration ball 8 can be assisted to be improved by utilizing the resistance of the deionized water, and displacement is not easy to occur due to slight fluctuation.
According to the intelligent monitoring system, the vital sign of a person can be monitored by the Internet of things sensing technology, the aim of preventing sudden disease death and detecting physiological and psychological abnormal criminals is achieved, various abnormal situations possibly existing in the criminals are intelligently identified through continuous monitoring of vital sign data, health data of the criminals can be collected when the criminals sleep without special cooperation of the criminals, therefore, the data are more accurate than chest card type data, the obtained data are more approximate to the situation of the criminals in an unconscious state after the criminals sleep, heartbeat and respiratory data transmitted by the person can be obtained in a contact-free state, the data can be uploaded to a server in a wireless mode after being obtained, active alarm and prompt of the abnormal situations can be achieved through client software after the data are analyzed, and the sleeping position of the criminals can be detected more accurately.
