Passive remote emergency button, application method thereof, and help-seeking system

Abstract

The invention provides a passive remote emergency button and an application method thereof. The emergency button is used for achieving a remote help-seeking function through pressing a key in needs or emergency. The emergency button comprises a magneto-electric induction device, an eMTC communication module group, a central processing unit, a central processor unit, a power management unit, a rectification processing unit, a button device body, and an energy storage capacitor. The emergency button does not need an external power supply or a battery for power supply through combining the eMTC communication technology with the passive magneto-electric induction device. There is no need of an additional GPS or other positioning chip, and the emergency button achieves the locating of a device. The emergency button is very wide in signal coverage, and the communication distance can reach several kilometers. The emergency button supports the positioning of a moving object, and can achieve the connection with a remote platform. The emergency button is low in cost, is small and exquisite in appearance, can be installed and fixed freely, and is good in market prospect.

Description

Technical field [0001] The invention relates to the technical fields of wireless communication technology, energy-saving technology and location-based services, in particular to a passive remote emergency button and its use method and help-seeking system. Background technique [0002] There are usually several methods for traditional emergency button, one-key help-seeking and other scenarios. The more common one is to use the one-key help function of the elderly phone through a mobile phone to dial a designated number for help, while smart phones use SMS, WeChat, etc. to ask for help. In this way, the shortcomings of using a mobile phone to achieve emergency help are obvious. First, you need to get the mobile phone. The mobile phone must have electricity. At the same time, the mobile phone must be operated. The process is cumbersome and not suitable for use in situations where personal safety is dangerous. Cause more harm to yourself. [0003] Another traditional way is to use an ...

[0002] There are usually several methods for traditional emergency button, one-key help and other scene applications. The more common one is to use the one-key help function of the elderly phone to dial the designated number for help through the mobile phone, while smart phones mostly use SMS and WeChat for help. The method, the shortcomings of using mobile phones to achieve emergency help are obvious. First, you need to get the mobile phone, the mobile phone must have power, and at the same time, you need to operate the mobile phone. inflict more harm on yourself

[0003] Another traditional method is to use an alarm device with GPRS function or SMS function, or a device using WiFi. This type of device also has the problem of working power, because such emergency or emergency help devices are generally rarely used. When it is really needed, it may not work properly because the battery is dead or not connected to the power supply. It will not be useful when it is urgently needed. It will cost money in the early stage and cause trouble in the later stage.

Moreover, the GPRS function consumes a lot of power, and the connection takes a relatively long time and is unstable; while using SMS for help, there may be mistakes due to human reasons, such as not checking in time, forgetting, missing, etc., and due to the limited environment, cannot pass on more information

At the same time, such devices generally rarely have positioning functions such as GPS. If positioning information is to be transmitted synchronously, a GPS-related positioning chip needs to be added, which increases hardware costs and equipment power consumption.

[0004] Other methods such as Bluetooth and infrared are generally suitable for short-distance home applications, which are limited by regions or regions. At the same time, it is impossible to realize the position positioning function without adding chips.
