Abstract

The invention discloses a nut detection device. The nut detection device comprises a first locking nut sensor, a second locking nut sensor, a third locking nut sensor, a fourth locking nut sensor, a direct current power supply and a programmable controller, wherein the first locking nut sensor, the second locking nut sensor, the third locking nut sensor and the fourth locking nut sensor are connected orderly in series, namely, a signal output end of the first locking nut sensor is connected with a power supply anode of the second locking nut sensor, the signal output end of the second lockingnut sensor is connected with the power supply anode of the third locking nut sensor, the signal output end of the third locking nut sensor is connected with the power supply anode of the fourth locking nut sensor, and the signal output end of the fourth locking nut sensor is connected with an input end of the programmable controller. The nut detection device provided by the invention is easy and convenient to mount, compact and regular in wiring, safe and reliable, and occupies less I / O.

Description

technical field [0001] The invention relates to the technical field of circuit control, in particular to a nut detection device. Background technique [0002] The pitching motion of the radar antenna is realized by the antenna lifting mechanism. On the one hand, the antenna lifting mechanism must play the role of supporting the antenna from rising and falling. On the other hand, it must enable the antenna to achieve accurate positioning at any position within the working range. There are 4 lock nuts. During the lifting process, all 4 lock nuts must be loosened to perform electric lifting. A lock nut detection circuit must be installed for protection. [0003] The traditional method is to install a detection sensor on each lock nut mounting frame, and all the signals of the four sensors are sent to the programmable controller for receiving signals and calculations for control, resulting in many wiring cables and large occupancy. The programming controller has many I / O ports ...
