Embodiment Construction

[0030] Below in conjunction with the embodiment image 3 Further explanation of the working engineering of the system in case of remote control:

[0031] The up, stop, and down signals generated by the three buttons K1, K2, and K3 of the remote control (1) are isolated through the photoelectric isolation coupler (2), and then shaped by the inverting Schmitt trigger (3). The signal of the signal is provided to the processor (14) by the OR gate circuit (4), and the program in the processor detects the flap F of the current mechanical transmission (13) sent by the sensor (10) after reading the code through the query mode. and the position signal of the pallet T, the magnetic steel N on the support shaft of the turnover plate F and the magnetic steel N1 on the pallet T pass through the magnetic induction sensor, so that the current position state is supplied to the processor through H1, H2, H3, H4, and the processor (14) According to the current H1, H2, H3, H4 signal and remote c...

Abstract

The invention provides a query-type remote control system, and belongs to the technical field of electronic control. The query-type remote control system is characterized in that a signal variable of a remote button and a signal variable of a terminal button are input to a processor through different coders, a signal decoding circuit of the terminal button is composed of a quanternary counting circuit, a signal coding circuit of the remote button is composed of a three-state binary coder, current motion and movement state signals in a mechanism device are input to the processor through multiple sensing circuits, codes of output signals of the processor are supplied to two motors through drive circuits, one motor controls motions of opening a cover or closing the cover, and the other motor controls a tray to move up and down. The software characteristics of the system include the steps of querying codes of an x1 input port, an x2 input port and an x3 input port, querying codes of Q1n and Q2n of a preceding state of an output port, and outputting codes of Q1n+1 and Q2n+1 after the codes of the x1, the x2, the x3, the Q1n and the Q2n are processed. The system has the advantages of being simple in circuit, stable in performance and the like.

Description

Technical field: [0001] The invention belongs to the field of electronic technology and relates to a query type remote control system. Background technique: [0002] At present, on the desktops of multimedia conferences, video conferences, command and dispatch conferences, production analysis conferences, financial analysis conferences, and various large conference rooms, it is required that the LCD monitor of the computer can be automatically hidden under the desktop at ordinary times. Under button operation or remote button operation, the LCD monitor will automatically rise to the desktop and be placed on the desktop stably. Although Japanese Patent Gazette discloses 2000-250, 2001-354521, and 2000-23761 patents, and Chinese patents disclose 02238102.3, 02292756.5, 200920194578.X, 200710123335.2, 200720152038.6. However, the above-mentioned patents only disclose the mechanical device or a part of the sensing circuit, but not the control circuit. Invention content: [0...
