Abstract
The utility model relates to an omnibearing infrared safety alarm which is composed of an infrared transmitting device 1, an infrared receiving device 2, a bearing 4, a multi-direction illuminating lamp 5, an alarm lamp 6, a sound escaping hole 7, a supporting rod 8, a pedestal 9, etc., wherein, the infrared transmitting device 1 and the infrared receiving device 2 are connected with each other by a rotating shaft 3, and infrared transmitting device 1 and the infrared receiving device 2 can rotate correspondingly. When the utility model is installed at the periphery of a construction field, the infrared light signal can be sent out and received mutually; thereby, the alarm can be sent out if an object crosses the line to block the infrared light. Because the infrared transmitting device 1 and the infrared receiving device 2 can rotate correspondingly, the utility model is suitable for the requirement of the irregular fields.
Description
The utility model is a kind of electronic installation, promptly a kind of comprehensive infrared safety alarm.
The alarm that utilizes the infrared optics principle to make is existing multiple at present, but all is the receiving trap of reporting to the police by receiving infrared-ray mostly.This form range of control is less, if use in the larger context, cost is higher, is unfavorable for popularization and application.In addition by a kind of alarm of forming by infrared emission and reception two parts device, though can control bigger scope, place but mostly be 90 degree between the infrared receiving/transmission camera lens in the existing product, thereby only be applicable to the use in rectangle place, do not adapt to the use in erose place.
The purpose of this utility model is that the direction of each infrared lens on a kind of same alarm of development all can be adjusted, and can adapt to the all-direction ultrared warner of different shape place needs.
Above-mentioned purpose is realized by following technical scheme: also be provided with infrared launcher and infrared receiving device on this alarm, different is to be connected by rotating shaft between infrared launcher and infrared receiving device.
Said infrared launcher is made up of the oscillatory circuit of two different frequencies and 3BG and infrared transmitting tube LED.
Said infrared receiving device is to be coupled by receiving circuit and frequency selection circuit, and joins with an AND circuit, language circuit, sound discharge road and power supply.
The alarm that adopts such scheme to make as long as be located at around the place, after the energising, can be received and dispatched Infrared mutually, shuts out the light as object, and alarm can be reported to the police immediately.Owing to be provided with rotating shaft between the infrared launcher of alarm and the receiving trap, can turn, thereby this alarm not only is applicable to the warning requirement in rectangle place, and can be suitable for erose places such as triangle, polygon, thereby solved the problem that prior art exists.
Introduce a kind of embodiment below in conjunction with accompanying drawing:
Fig. 1 is the front view of present embodiment, and Fig. 2 is its vertical view.
Fig. 3 is the infrared launcher circuit diagram.
Fig. 4 is the infrared receiving device circuit diagram.
