Abstract

A mining amplified telephone automatic identification system relates to mining communication equipment, and comprises a single-chip microcomputer; wherein the single-chip microcomputer is respectively connected with a first receiving module and a second receiving module through two input pins, and is respectively connected with a first sending module and a second sending module through two output pins; the single-chip microcomputer is also connected with a detection module, the detection module is connected in parallel with a locking switch, the locking switch is connected with cable ports through emergency stop lines; the first receiving module and the first sending module are connected with a previous cable port through querying lines; and the second receiving module and the second sending module are connected with a next cable port through querying lines. By adopting the mining amplified telephone automatic identification system of the utility model, a mining intrinsic safe type control box can have a function of displaying states of equipments such as the amplified telephones, on-off switches, and so on along the line, thereby effectively helping workers and maintenance personnel analyze status along the line, and greatly raising a working efficiency; in addition, the mining amplified telephone automatic identification system of the utility model consumes extremely little current, thereby greatly reducing influences on power supply voltages along the line.

Description

Mining hands free telephone automatic recognition system

Technical field

The utility model relates to a kind of mining communication apparatus, specifically a kind of mining hands free telephone automatic recognition system.

Background technology

In mining face communication control device or mine belt conveyor protective device, mine intrinsic safety type control cabinet is a master controller, can reach equipment such as 20 intrinsic safety type locking hands free telephones, intrinsic safety type start stop switch as required.The platform number and the state of connected equipment can not discerned and show to mine intrinsic safety type control cabinet at present; Can not be difficult to accurately deal with an urgent situation for the staff provides the method for differentiating mining face communication control device or mine belt conveyor protective device operating state simply and effectively.

The utility model content

The purpose of the utility model is to provide a kind of mining hands free telephone automatic recognition system, solves the above problems.

The utility model solves the technical scheme that its technical problem adopted: mining hands free telephone automatic recognition system; It is characterized in that native system comprises single-chip microcomputer, single-chip microcomputer connects first receiver module and second respectively through two input pins and accepts module; Connect first sending module and second sending module respectively through two output pins; Single-chip microcomputer also is connected with detection module, and detection module is parallelly connected with latch switch, and latch switch links to each other with cableport through suddenly stopping line; Described first receiver module links to each other with a last cableport through information trunk with first sending module, and described second receiver module links to each other with next cableport through information trunk with second sending module;

Described single-chip microcomputer adopts the MSP430 single-chip microcomputer.

The beneficial effect of the utility model is: on mine intrinsic safety type control cabinet, show the function of equipment states such as locking hands free telephone along the line, start stop switch, help staff and maintenance personal to analyze situation along the line effectively, improved operating efficiency greatly.The utility model current sinking is extremely low, greatly reduces the influence to supply voltage along the line.The cableport of the utility model is non-directional, does not have the misgivings of wrong.
