Problems solved by technology

[0002] The existing technology of elevator voice broadcast mainly has the following shortcomings: (1) the broadcast content is too simple, and can only broadcast one or two simple sentences; When the announcement starts, passengers often leave the elevator before they have finished listening
The problem mainly lies in the signal that triggers the voice broadcast, that is, the appropriate trigger signal is not obtained from the elevator

Embodiment Construction

[0010] As shown in Figure 1, the elevator voice announcement device comprises audio power amplifier circuit 5, the elevator signal acquisition circuit 1, system isolation circuit 2, single-chip microcomputer and its peripheral circuit 3, output end connected audio chip circuit 4 of audio power amplifier circuit 5 connected successively. The "elevator panel" referred to in this manual refers to the buttons and display parts accessible to the elevator user. The user presses the floor number keys on the elevator panel to select the corresponding target floor. "Elevator control panel" means the portion of the circuit board behind the elevator panel that is not visible to the user. The elevator signal acquisition circuit 1 takes out the elevator up and down signals, door closing signals and floor signals from the elevator control panel. Processing, that is, it supports the programmatic way to scan and collect signals from the elevator panel under the control of the single-chip micr...

Abstract

The invention provides a voice broadcasting method for lift, comprising following steps: (1) initialization, selecting current floor; (2) scanning elevator panel and quantizing all of target floors information selected by users; (3) sorting the data of the stored target floor; (4) judging whether existing effective target floor information, returning to step (2) if the result is NO; (5) detecting whether existing closing signal if the result in step (4) is YES, returning to step (2) if the result is NO; (6) judging the elevator up or down if the result in step (5) is YES; (7) judging the nearest floor of the elevator and storing; (8) calling voice for playing subprogram; (9) storing the elevator nearest floor having played voice as current floor.

Description

technical field [0001] The invention relates to a voice broadcast method, in particular to a voice broadcast method applied to instant broadcast of elevator floor information. Background technique [0002] The existing technology of elevator voice broadcast mainly has the following shortcomings: (1) the broadcast content is too simple, and can only broadcast one or two simple sentences; When the announcement starts, passengers often leave the elevator before they have finished listening. The former situation mainly occurs in the voice announcement device that comes with the elevator itself, because the same type of elevator has the same broadcast content when it leaves the factory, so the specific requirements of each customer cannot be realized; the latter situation is mainly because there is no Make full use of the effective broadcast time during elevator operation. It takes about 3 seconds for medium and high-end elevators to run between two adjacent floors, but it take...
