Industrial-grade 4G full Netcom short message and telephone ringing alarm terminal and its alarm method

Abstract

The invention discloses an industrial-grade 4G full-network short message and telephone ringing alarm terminal and an alarm method thereof. The alarm terminal is composed of a central processing unit, a 4G full-network modem unit, a SIM card unit, a switch input state detection unit, an analog Acquisition unit, switch output control unit, level conversion unit, communication interface unit, LED indicator unit, internal and external power supply monitoring and power seamless switching unit, watchdog control unit, power management unit and lithium battery charging management unit; Its alarm method includes the following steps: (1) device parameter setting; (2) power-on initialization; (3) detection and entering the ready state for sending text messages, and when an event occurs, start text message alarm and phone ringing reminder. The invention can send alarm short messages to multiple people at the same time and remind the receiving objects of the short messages in time; the device has various detection signals, and the content of the alarm short messages can be flexibly set, and the like.

Description

technical field [0001] The invention relates to an alarm device, specifically an industrial-grade 4G full-network short message and telephone ringing alarm terminal and an alarm method thereof. Background technique [0002] 4G communication technology is the abbreviation of the fourth generation mobile communication technology, and G is the abbreviation of generation (generation). The 4G communication system can download at a speed of 100Mbps, which is 2000 times faster than the current GSM / CDMA dial-up Internet access, and the upload speed can also reach 20Mbps, and can meet the various requirements of almost all users for wireless services. The 4G communication system is compatible with 2G and 3G network communication and SMS functions, that is to say, in places where the 4G network signal is not good, it can automatically switch to 3G network or even 2G network to meet the user's service requirements for voice, SMS and data communication to the greatest extent. .

AI Technical Summary

Problems solved by technology

[0004] Traditional SMS alarms generally only have a single network standard, such as China Mobile's GSM or China Unicom's GSM or China Telecom's CDMA, so the single-mode terminal equipment purchased by users may be inconsistent with the network signal of the local operator when using it. Coverage conflicts occur. For example, the signal of China Mobile is strong in some places, and the signal of China Telecom is strong in some places, so that users cannot flexibly choose the best network operator service according to the actual situation; 2G network SMS has a long delay; due to The technical problems of the manufacturer lead to a high failure rate of SMS sending; the alarm SMS cannot be sent to multiple people at the same time; the recipients of the SMS cannot be reminded in time (especially the occurrence of important events); the device detection signal is single; the content of the alarm SMS cannot be flexibly set ; The backup battery is not used or the backup battery is used without low power consumption processing, resulting in a shorter backup battery life, etc.
