Abstract
The invention discloses a mining intrinsically safe closed-end amplified phone circuit device, which comprises an 18V intrinsically safe power module, a charging control circuit, a voice amplifier, a dotting output module, a front-end voice amplification module and a signal switching processing module, wherein the 18V intrinsically safe power module is connected with the charging control circuit through a connecting terminal; the charging control circuit is connected with the voice amplifier, the dotting output module, the front-end voice amplification module and the signal switching processing module respectively; the voice signal output end of the signal switching processing module is connected with the voice amplifier which is connected with a loudspeaker; and the signal switching processing module is connected with a dotting device through a dotting button and a transmitter button. The device can be used for voice communication, can stop and lock equipment such as a motor when used together with various electrical control devices to ensure the safety of personnel and the equipment, and also can control external equipment.
Description
Technical field
The present invention relates to a kind of hands free telephone, specifically is a kind of mining intrinsic safety type enclosed type hands free telephone circuit arrangement, and this hands free telephone is applicable to rubber conveyer working face under the coal mine, getting working face communication and control use.
Background technology
At present, the quantity of China's coal-mine down-hole belt feeder is quite a lot of, and the control section of belt feeder is formed for the components and parts (as: contactor, relay etc.) that separate mostly.This control appliance volume is big, failure rate is high, maintenance is inconvenient, the especially transportation in the down-hole, very inconvenient when installing.
In addition, existing mining down-hole public address set is difficult to carry out supporting use with various electrical control gears, more can not shut down and locking equipment, and the safety that ensures the person and equipment is brought hidden danger.
Summary of the invention
The present invention seeks in order to overcome above-mentioned defective, provide a kind of compact conformation, volume little, transport, install, debug enclosed type hands free telephone easily.
Technical scheme of the present invention is:
A kind of mining intrinsic safety type enclosed type hands free telephone circuit arrangement; Comprise 18V intrinsic safety electric source module, charging control circuit, speech amplifier, get output module, front end voice amplification module and signaling switch processing module ready; Said 18V intrinsic safety electric source module connects charging control circuit through binding post; Charging control circuit connects speech amplifier respectively, gets output module ready, front end voice amplification module and signaling switch processing module; The voice signal output of signaling switch processing module connects speech amplifier; Speech amplifier connects loud speaker, and the signaling switch processing module connects device for dotting through getting button ready, and the signaling switch processing module connects device for dotting through press-to-talk switch.
The signal input part of said signaling switch processing module connects the voice signal line.
The invention has the beneficial effects as follows:
Enclosed type hands free telephone circuit arrangement of the present invention; Be mining intrinsic safety electro gas equipment; Be applicable to the environment that gas, coal dust explosion hazard are arranged under the coal mine, also be applicable to adverse circumstances such as metallurgy, building materials, mine and coal preparation plant, steel plant, cogeneration power plant, harbour.Can be used for speech communication and various electrical control gear when supporting, can shut down and locking equipment (like motor) again, guarantee the safety of the person and equipment, can also control external equipment etc.
Of the present invention can being widely used in has in the environment of damp (methane) and coal dust, and it is simple to operate, and is easy to use.As long as press " sending words " button during use, can carry out single worker's conversation; Press " locking " button left, the right rotation button, can realize locking, send one simultaneously and often open no electric potential contact signal.The button opposite spin, make that red point on the button is aimed at the red point on the outer rim after, button is extracted can be realized release again.

The signal input part of signaling switch processing module connects the voice signal line.
Fig. 1 is an electrical principle block diagram of the present invention.Supply power voltage is the 18V intrinsic safety electric source, and the binding post through Fig. 2 is introduced, and phone comprises sending and receives words part, early warning transmitting section and the anxious latching segment of closing down; Voice in the phone are accepted part and are being detected voice lines always, and when the signal on the voice lines during less than 400mV, voice are accepted part and quit work; When the signal on the voice lines time more than or equal to 400mV; Voice are accepted part and are started working, and voice signal is amplified, and are sent out by loud speaker; If signal is less than 400mV, the phone cut-out of will delaying time.When power line connected, phone was in charged state, and charging divides three gears: it is 18mA that first toggle switch is put in the ON position; It is 23mA that second toggle switch is put in the ON position; It is 34mA that first toggle switch, second toggle switch are all put in the ON position.
Embodiment recited above describes preferred implementation of the present invention; Be not that design of the present invention and scope are limited; Do not breaking away under the design concept prerequisite of the present invention; Common engineers and technicians make technical scheme of the present invention in this area various modification and improvement all should fall into protection scope of the present invention, and the technology contents that the present invention asks for protection all is documented in claims.
