Seat condition monitoring system based on photoelectric starting real-time detection

Abstract

The invention discloses a seat state monitoring system based on photoelectric start-up real-time detection, which includes the minimum system of the lower computer STC89C52 and the minimum system of the upper computer STC89C52 corresponding to the seat one by one; Communicate with the lower computer NRF24l01 wireless transceiver and the lower computer STC89C52 minimum system; the upper computer STC89C52 minimum system is normally closed, and is connected to the power supply through a relay, and the start of the relay is controlled by a photoelectric sensor; the lower computer STC89C52 minimum system It is also connected with PC and LED display. The present invention adopts the route of first detection and then control, rather than the usual route of first control and then detection, which solves the problem of power consumption very well. We use the photoelectric sensor to start the relay for detection-control, so that the MCU controller It does not need to be in a constant startup state, thereby effectively reducing power consumption.

Description

technical field [0001] The invention relates to a monitoring system, in particular to a seat state monitoring system based on photoelectric start-up real-time detection. Background technique [0002] The university library is favored by teachers and students for its quiet and comfortable reading environment and the advantages of convenient access to learning resources. However, the number of seats often cannot meet the needs of teachers and students. However, the number of seats in the library is limited, and there are serious problems such as students occupying seats and administrators supervising air crashes. At the same time, students not only spend a lot of time looking for vacant seats, but also make noises in the process of finding seats, which disturbs the order of the self-study room and disturbs the self-study students. Anyone who has college experience will deeply remember the spectacular queue at the library gate before dawn. Seats in the library are the most "...

Problems solved by technology

[0006] The purpose of the present invention is to provide a seat state monitoring system based on photoelectric start-up real-time detection. The present invention adopts the route of detection first and then control instead of the usual route of control first and then detection, which solves the problem of power consumption very well. We use the photoelectric sensor to start the relay for detection-control, so that the MCU controller does not need to be in the normal startup state, thereby effectively reducing power consumption and saving electric energy
