Abstract

The invention discloses a separated type photoelectric control device capable of being installed in a separating mode. The separated type photoelectric control device is used for measuring a material level and a liquid level and comprises an optical detecting head and a signal processing unit. The optical detecting head is separably connected with the signal processing unit and can judge the locking state or the separating state of the optical detecting head and the signal processing unit. The signal processing unit comprises a light emitting module, a light receiving module, a signal processing module and a signal outputting module. An optical path of a light signal is changed by an object to be detected, and the light signal is sent to the light receiving module. The light receiving module sends the light signal to the signal processing module, the signal processing module analyzes and processes the light signal so as to obtain an output signal and send the output signal to the signal output module, and the output signal is outputted. According to the separated type photoelectric control device capable of being installed in the separating mode, the state of the object to be detected does not need to be changed and outputting of various simulation alarm signals can be performed; meanwhile, locking or separating of the optical detecting head and the signal processing unit can be judged.

Description

technical field

[0001] The invention relates to the field of photoelectric control, in particular to a detachably installed separated photoelectric control device. Background technique

[0002] The operating principle of the existing photoelectric switch measuring device is as follows: figure 1 As shown, it includes an optical transmitter (13), an optical receiver (14), a signal processing unit (15), and a signal output circuit (16).

[0003] When the object to be measured does not exist and the object to be measured appears, there will be two different light receiving states, one is that the light receiver has received a signal, or has not received a signal. After signal processing, the transformation of the signal can treat the photoelectric measuring device as a switch device for controlling other back-end equipment.

[0004] Under normal circumstances, the above-mentioned conventional technology can only correctly output the state of measuring whether the object under ...
