Description

The intercom of a tractor serves several purposes

Technical field

The utility model relates to a kind of intercom, and is especially a kind of with train wireless dispatch communication function and the intercom that construction contact, security protection intercommunication function unite two into one, and belongs to the communication apparatus technical field.

Background technology

In railway system's transportation guarantee process, AT STATION in the scope, take Transportation Organization as main transportation department, the communication that mainly adopts the train wireless dispatch communication of dispatch control train operation to combine with the contact of transporting less important work.AT STATION with circuit on, the electricity take repair apparatus, circuit as main body is engaged in, works department, then the main communication that adopts construction contact, security protection to combine with the Radio train dispatching monitoring.In these two kinds of communications, the Radio train dispatching communication belongs to railway Special answering machine, and construction contact and security protection belong to common intercom with communication, so the staff of these departments needs to be equipped with this two kinds of intercoms at present, could satisfy need of work, so just strengthened the heavy burden that the staff carries two kinds of intercoms and reserve battery, in working at the scene, no matter be communication, still operation is used and is carried etc., all makes troubles to the staff.Therefore, be necessary prior art is improved.

Summary of the invention

For alleviating staff's heavy burden, be convenient for carrying, simplify the operation, the utility model provides a kind of intercom of a tractor serves several purposes.

The utility model provides a kind of like this intercom of a tractor serves several purposes, comprise housing, be located at the power supply in the housing, and by the radio-frequency (RF) transceiver of being located in the housing, the controller that is electrically connected with radio-frequency (RF) transceiver, the audio process that is electrically connected with controller, with the antenna that is electrically connected with radio-frequency (RF) transceiver of being located on the housing, the mains switch that is connected with power supply, what be electrically connected with controller controls part, the microphone that is electrically connected with audio process and loud speaker, the Radio train dispatching commander communication means that consists of, characterized by further comprising by the Radio train dispatching pilot valve that is electrically connected with controller of being located in the housing, the operation contact that contact protection communicator consists of, the security protection communication means, and be provided with the function switching key that is electrically connected with controller at housing, state voice reading button.With according to actual needs, operating function switching key, state voice reading button, carry out railway transportation Train Dispatch ﹠ Command communication or maintenance construction operation contact, the security protection intercommunication is switched and enter for.

Described controller is conventional programmable controller, and model is M30622.

Described housing is provided with the DLL (dynamic link library) that is electrically connected with controller.

The part of controlling that is electrically connected with controller on the described housing comprises conversation emission PTT key, channel knob, indicator light, Radio train dispatching call button.

The utlity model has following advantages and effect: adopt such scheme, the Train Dispatch ﹠ Command communication system that is about to railway transportation unites two into one with the contact of maintenance construction operation, security protection communication system, and by the function switching key, just can easily mutually switch, on an intercom, just can finish the Train Dispatch ﹠ Command communication function, and the maintenance construction operation is got in touch with, the security protection communication function, both handled easilies, be convenient for carrying again, greatly alleviate staff's heavy burden, reduce labour intensity, increase work efficiency.Be a desirable a tractor serves several purposes intercom in fact.
