Problems solved by technology

[0004] Faults caused by hardware equipment failures or abnormalities in some important functions, such as code errors in a physical line, fiber breaks, physical line failures, etc., if not handled in time, the equipment will not operate normally
Although protection circuits are widely used in various electronic communication equipment, most of the existing protection circuits use current-limiting resistor protection and fuse protection, the protection function is single, the protection accuracy is not high, and it cannot protect the product equipment very well. During the electrical aging of batch products in the production and manufacturing of electronic equipment, it cannot play the role of real-time monitoring, status judgment, power-off protection, and prompting and alarming, and cannot meet the needs of production and manufacturing.

Abstract

The invention provides a full-state monitoring and power failure protection alarm circuit and aims to provide a protection alarm circuit having properties of low cost, powerful functions and wide application. The alarm circuit is characterized in that a solid relay connected with a status monitoring unit is connected with a sound and light rotation prompter through a built-in switch output end, anAC switch is connected in series through an AC access wire with a built-in switch input end of the solid relay to constitute an AC loop of a sound and light prompting alarm unit. When a monitored load works normally, the positive power is supplied to the monitored load through a power-off control relay normally-on group switch and passes through a current monitor to the ground to form a power supply loop, a working status of the monitored load is monitored by the current monitor in real time, signal changes detected in real time are sent to left and right two positive signal access points ofan upper half of a comparator through a no-load switch normally-on group switch, signal reference is completed for left and right two negative signal access points of the upper half of the comparator,and the sound and light rotation prompter is connected with the AC power supply loop to realize the alarm.

Description

technical field [0001] The invention relates to a monitoring and protection system widely used in local circuit monitoring and protection, electronic equipment work monitoring and protection, industrial production automation equipment monitoring and protection, various types of product equipment electric aging work monitoring and protection, and multiple sets of product equipment working separately under DC conditions. [0002] technical background [0003] Electronic communication products widely used in industrial production, especially in the electronics manufacturing and aerospace fields, have clear requirements for product burn-in and rejection tests in the production process. The so-called burn-in rejection test refers to applying a certain stress to components or products within a certain period of time, such as voltage, current, temperature, etc., and usually higher than the stress of normal use, the purpose is to eliminate some defective components, A screening metho...
