Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] figure 1 Among them, the ID code encoding circuit is composed of the dialing chip IC1 of the model TCM5087, etc., and the input pins COL1, COL2, COL3, COL4, ROW1, ROW2, ROW3, ​​ROW4 of the dialing chip IC1 are connected and welded as required, and there are 16 types Combination, choose one for each walkie-talkie. Among them, pins 7 and 8 of the dial-up chip IC1 are connected to an oscillation circuit I composed of capacitors C1, C2 and quartz crystal C0. Its selectable frequency range is 430-530KHz. In practice, a frequency of 480KHz is used. The oscillation signal is provided to the dial-up chip IC1. Pulse signal. The dial chip IC1 generates continuous DTMF codes representing identity codes, and its model can also be MK5087 or CSC5087 or GF5087 or TP5087 or MT5087 or UM95087 or WE9187 or CIC9187 or S2559 or LH2559 or SBA5091 or LR4087 or MK538...

Abstract

This invention discloses an intercom remote control device with an identity code function including an emit circuit and a receive circuit, in which, the emit circuit is connected with the identify code encoding circuit, which emits double-phone multi-frequency identity code signals having different frequencies with the double-phone multi-frequency control signals of the emit circuit, which are transmitted together with the control signal emitted by the emit circuit, said receiver circuit is connected with the decode circuit of the identity codes sending the decoded identity code signals to the single-chip processor IC2 control circuit, which executes the operation of the control signal if the decoding signal meets the agreement, otherwise it does not.

Description

technical field [0001] The invention relates to a remote control device, in particular to a walkie-talkie remote control device with an identity identification function using the walkie-talkie. Background technique [0002] A walkie-talkie is a device that can communicate over a long distance. People take advantage of its long-distance communication characteristics and use it as a remote control device. At present, walkie-talkies are used as remote controls in many workplaces that require remote control to control the operation of certain equipment. Its working principle is: use the digital keyboard of the walkie-talkie (that is, the dialing circuit) to send a DTMF (dual-tone multi-frequency) code, which is received and decoded by the remote receiver (walkie-talkie, vehicle-mounted station, base station, etc.), and then sent to the computer for control. certain equipment. However, there is a problem in the existing walkie-talkie-type remote control equipment, that is, ther...
