A safety warning device for prison police

Abstract

The invention discloses a safety alert device for the people's policeman in a prison management department. The device is composed of a real-time positioning module, an attitude measurement module, a micro control unit, a pulse monitoring module and a voice compression module and is used for monitoring the policeman on duty in a prison management department in real time to effectively prevent an attach or injuries on the policeman; and the provided device is a safety alert terminal capable of realizing the voice intercom function. According to the device, state monitoring is carried out on the policeman on duty in a prison management department by combining a three-axis acceleration sensor, a three-axis geomagnetic sensor and a three-axis gyroscope sensor; and because of combined usage of various sensors, the false alarm rate is substantially reduced; on the basis of a signal-strength-based zigbee wireless positioning technology, seamless indoor and outdoor positioning can be realized to eliminate the restriction of indoor application of satellite positioning. Meanwhile, a pickup unit can be turned on automatically to upload environment sound data. Besides, with a pulse sensor, the health state of the policeman in the prison management department can be monitored at any time at any place and thus diseases like the high blood pressure or arrhythmia can be found timely, so that alarming can be carried out automatically.

Description

technical field [0001] The invention relates to an embedded security alert intelligent device, in particular to a security alert device for prison police. Background technique [0002] Public security supervision The police undertake the tasks of guarding and guarding criminal suspects, defendants, criminals, offenders, and mentally ill persons subject to compulsory medical treatment, enforcing criminal penalties, administrative penalties, education, treatment of specific diseases, and psychological and behavioral corrections in accordance with the law. The progress of public security supervision work is inseparable from the dedication and contribution of the public security supervision police. Although the number of police officers supervised by public security has increased in recent years, it is still obviously insufficient compared with the tasks undertaken. According to statistics, the ratio of the national public security supervision police to the supervised personnel...

AI Technical Summary

Problems solved by technology

[0004] Deficiencies in existing related technologies: In practical applications, personnel status monitoring and alarming are mainly divided into three categories: the first category is based on video monitoring for status analysis; the second category is based on acoustic status detection systems; the third category It is based on the intelligent perception of wearable devices for state analysis

Video surveillance technology is susceptible to interference from various factors such as light, temperature, and personnel coordination, and has extremely high requirements for the monitoring environment. If one of the above conditions is not met, personnel status monitoring based on video surveillance technology will produce a high false alarm rate. or even completely useless

And the system construction cost is very high

[0006] The second type of technology and equipment is to monitor by analyzing the audio signal when falling, which can monitor only a single type of personnel status, and is very vulnerable to external interference, resulting in a high false alarm rate of the system

[0015] The above-mentioned state monitoring devices often have disadvantages such as high false alarm rate, low intelligence, few types of monitoring states, inability to perform indoor positioning, high cost and high power consumption, and cannot meet the daily work needs of prison police officers.
