Display device and display method of working state of interphone

Abstract

The invention relates to interphones, and provides a display device and display method of the working state of an interphone. The display device and display method of the working state of the interphone can effectively display a working channel where an interphone product stays, signal strength, electric quantity and other working states, provides multichannel grouping selection, increases a great number of available channels and is low in production cost. The display device and display method of the working state of the interphone comprises a single-chip microcomputer, an LED lamp set, buttons and a channel register connected with the interphone, the single-chip microcomputer is connected with multiple channels on the channel register and controls switching of the multiple channels on the channel register, the output end of the single-chip microcomputer displays the channel set where the interphone located in a current work state through the LED lamp set, and the buttons are connected with the control end of the single-chip microcomputer and control the switching of the multiple channels on the channel register through the single-chip microcomputer. When a user presses down the button standing for contents to be check currently, the single-chip microcomputer connects corresponding detecting circuits or the channel register according to the instructions represented by the button pressing action, and the current working state of the interphone is output and displayed through the LED lamp set.

Description

technical field [0001] The invention relates to a walkie-talkie, in particular to a working state display device and a display method of the walkie-talkie. Background technique [0002] With the continuous development of domestic walkie-talkie technology and the requirements of various industries for walkie-talkie products, walkie-talkies are gradually divided into two categories. One type is amateur walkie-talkies used by amateurs. This type of walkie-talkie has an LCD screen that can clearly display the working status of the walkie-talkie, but it is more expensive and has high production costs. It is also broken when dropped, and the cost of replacement and maintenance is too high, which does not meet the status quo commonly used in the existing market. The other type is professional walkie-talkies. This kind of professional walkie-talkies generally prevents misoperation and keeps the frequency of use confidential, as well as product reliability and adapts to harsh workin...

AI Technical Summary

Problems solved by technology

At present, professional walkie-talkie products on the market mainly use 16-speed encoders as the selection of 16 storage channels. The selection of 16 communication channels is selected through the knob set at the antenna, but it is impossible to clearly understand the working status of the walkie-talkie and Which channel to work on, signal strength, battery status, etc.

In particular, most of the walkie-talkies on the market do not emit a prompt until the battery is basically exhausted. At the same time, a walkie-talkie has only 16 channels, which is too small. If there is channel interference, it is required for large enterprises, large event venues and other places to use multiple channels. The existence of separate communication is not enough, so how to realize the display of working status, increase channels and effectively control costs on professional machines has become an urgent demand in the market

Although the existing professional walkie-talkies also have some display devices that display the working power of the walkie-talkie through indicator lights, they still cannot display and increase the working channel of the walkie-talkie at low cost.
