Embodiment

[0026] The working power supply 1 is a built-in 12V / 500mAH rechargeable lithium battery, which provides working power for other functional modules and components of the device. Lithium battery charging. When the device is working, it can be hung at any position in the dangerous area as required. When someone enters the dangerous area, the pyroelectric infrared sensor 2 senses and collects the infrared signal, and transmits the signal to the infrared sensor signal processor 3, which is controlled by the infrared sensor. The signal processor 3 identifies and processes the signal, judges whether there is indeed a person intruding into the dangerous area, and outputs the sensing state trigger signal to the main controller 4, and the main controller 4 judges that the signal sent by the infrared sensor signal processor 3 is triggered. State, output driving signal, drive indicator light or externally expanded warning light to work, emit light for alarm. At the same time, the main c...

Abstract

The invention discloses a hazardous area infrared ray alarm system. The hazardous area infrared ray alarm system mainly comprises a working power source, an infrared monitoring device and an intelligent sound-light alarm device. The infrared monitoring device comprises at least one pyroelectric infrared sensor arranged in a hazardous area. The pyroelectric infrared sensor is connected with a master controller through a connected infrared sensor signal processor. The intelligent sound-light alarm device comprises a caution lamp, a voice recording and playing device, an audio power amplifier and a loudspeaker. The master controller is connected with the caution lamp, the audio power amplifier and the voice recording and playing device with a TF card slot, and the master controller and the voice recording and playing device carry out voice playing by the connected audio power amplifier through the loudspeaker. The working power source is a 12V / 500mAH rechargeable built-in type lithium battery module. The lithium battery module is provided with a charging port capable of charging a lithium battery through an external charger. The hazardous area infrared ray alarm system has the advantages of being simple in structure, convenient to use, high in reliability and the like.

Description

technical field [0001] The invention relates to an infrared warning system in a dangerous area, which belongs to the field of electric equipment tools. Background technique [0002] With the rapid development of my country's economy and society, the electricity consumption of the society is increasing year by year. At present, there are a large number of old substation capacity expansion projects and new substation construction projects every year to improve the power supply capacity of substations to meet the rising demand. To ensure the reliability of electricity consumption of users. In the process of increasing the capacity of the old substation and the construction of the new substation, civil works such as the excavation and construction of the main transformer foundation, cable trenches, drainage ditches, and oil storage tanks will be involved. Due to the stages of civil construction, the holes and ditches excavated during the civil construction were not backfille...
