Embodiment Construction

[0011] Specific embodiments of the present invention will be further described in detail below.

[0012] Such as figure 1 As shown, an induction counting alarm device of the present invention uses 220V mains as the power supply, and the power supply is first connected to the overcurrent protection switch, and then connected to other devices to enhance its safety. The power supply is connected to the alarm and the transformer, and the transformer provides 24V direct current for the counter and the sensor. The counter is connected to the alarm through the relay.

[0013] When the induction counting and alarming device of the present invention is working, the upper limit value of the counter alarming is manually set at first. After the sensor detects the alarm source, it sends a signal to the counter, and the counter counts. When the accumulated number of signals received by the counter reaches the upper limit of the alarm, the counter is turned on, and the alarm starts to alar...

Abstract

The invention discloses an inductive counting alarm device, comprising an alarm and a power supply. The inductive counting alarm device is characterized in that the alarm is connected with a counter through a circuit, and the counter is connected with an inductor through a circuit. According to the inductive counting alarm device provided by the invention, the sensitivity of the alarm is adjusted by the counter, only when the counter reaches preset induction times, the alarm starts working, thus the alarm is adjusted to the optimal sensitivity according to the actual condition so as to prevent false alarm and missed alarm. The inductive counting alarm device provided by the invention has the advantages of simple structure, convenience for use, safety and reliability and the like.

Description

technical field [0001] The invention relates to an alarm device, in particular to an induction counting alarm device. Background technique [0002] In order to ensure safety in industrial production, alarms are often used. The sensitivity of the alarm is an urgent problem to be solved. If the sensitivity of the alarm is too high, there will be frequent alarms, which will affect the working environment and disrupt normal production; if the sensitivity of the alarm is too low, it will be easy to fail to report and cause serious safety hazards. [0003] Contents of the invention [0004] The present invention provides a solution to the above problems, and provides an induction counting alarm device with simple structure, safety and ease of use. [0005] The technical solution of the present invention is to provide an induction counting alarm device, which includes an alarm and a power supply, and is characterized in that: the alarm circuit is connected to a counter, and th...
