The invention relates to a reminder for safety production, and relates to an electronic reminder. The reminder consists of a circuit board, a micro loudspeaker, a battery, a switch, a charging port and a shell, wherein the circuit board, the micro loudspeaker and the battery are arranged in the shell, and the switch and the charging port are arranged on the side of the shell; the second pin of a timing resistor is connected to the anode of a timing capacitor, the input end of a NOT gate and the first pin of a discharging resistor, and the second pin of the charging resistor is connected to the anode of a discharging diode; the output end of the NOT gate a is connected to the input end of a NOT gate b, the first pin of the timing resistor and the cathode of the discharging diode, the output end of the NOT gate b is connected to the trigger end of a solid speech circuit, the output end of the solid speech circuit is connected to the base electrode of a triode b through a biasing resistor b, and the collector electrode of the triode b is connected to the output end of the switch through the voice coil of the micro loudspeaker. The reminder for safety production disclosed by the invention is worn on every manager and every production people, so that the safety production is reminded and warned, and liability accidents are avoided or reduced.
Description
technical field [0001] The invention relates to an electronic circuit, in particular to an electronic reminder. Background technique [0002] Work safety is related to the fundamental interests of the broad masses of the people, and the responsibility for safe production is heavier than Mount Tai. [0003] The so-called safe production refers to the relevant activities in the production and operation activities, in order to avoid accidents that cause personal injury and property loss, and take corresponding accident prevention and control measures to ensure the personal safety of employees and the smooth progress of production and operation activities. . In the production process, safety is the most important thing, safety must be the first priority, and safety production responsibilities must be fully performed. [0004] my country's safety production policy is "safety first, prevention first, comprehensive management", the basic idea is "safety production, everyone is re...
