Preferably, described key board unit comprises: keyboard, comprises talk key, switch key and dial key; Keyboard management chip, is connected with keyboard, for real time scan keyboard to send push button signalling; Wherein, at described push button signalling, be talk key while being pressed, described control command is for carrying out half-duplex operation, at described push button signalling, is switch key while being pressed, and described control command is for carrying out full-duplex communication.
Preferably, described control device is single-chip microcomputer.
Preferably, this equipment also comprises: voice device, is connected with described control device, for playing voice.
Preferably, this equipment also comprises: recording device, is connected with described control device, for storing communication content.
Preferably, this equipment also comprises: CAN bus driver, be connected with described control device, and provide to the interface of CAN bus.
Pass through technique scheme, the utility model is by combining half-duplex operation device and full-duplex communication device with key board unit and control device, on railway locomotive, realized the communication mode that integrates half-duplex operation and full-duplex communication, in addition the equipment providing by the utility model, can also carry out the switching of half-duplex operation and full-duplex communication.
Other feature and advantage of the present utility model partly in detail are described the embodiment subsequently.
Accompanying drawing explanation
Accompanying drawing is to be used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model, but does not form restriction of the present utility model with embodiment one below.In the accompanying drawings:
Fig. 1 is the structural representation of the intercom that provides of the utility model; And
Fig. 2 is the structural representation of the intercom that provides of the utility model preferred implementation.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.Should be understood that, embodiment described herein only, for description and interpretation the utility model, is not limited to the utility model.
Fig. 1 is the structural representation of the intercom that provides of the utility model, and as shown in Figure 1, this equipment comprises key board unit, control device, half-duplex operation device and full-duplex communication device.Key board unit is used for sending push button signalling, control device is connected with key board unit, the push button signalling sending according to key board unit sends corresponding control command, half-duplex operation device is connected with control device, for the control command of sending according to control device, carry out half-duplex operation, full-duplex communication is similarly connected with control device, for the different control command of sending according to control device, carries out full-duplex communication.
Wherein, key board unit comprises keyboard and Keyboard management chip, on keyboard, be provided with talk key, switch key and dial key, Keyboard management chip is connected with keyboard, and keyboard is for example carried out to real time scan, to send corresponding push button signalling,, at the push button signalling sending, be that talk key is when be pressed, the control command that control device sends is for carrying out half-duplex operation, at the push button signalling sending, is switch key while being pressed, and the control command that control device sends is for carrying out full-duplex communication.
Specifically, the intercom that those skilled in the art easily understand the utility model to be provided can comprise talking handle, intercom default conditions are half-duplex operation state, when operating personnel take this talking handle, intercom, in half-duplex operation state, it will be readily appreciated by those skilled in the art that now by repeating press-to-talk key and unclamping talk key and can carry out half-duplex operation.When operating personnel need to carry out full-duplex communication, press the switch key on lower keyboard, intercom will be in full-duplex communication state, now press again the corresponding button of verbal system (being similar to telephone number) of required connection, can be communicated with the verbal system of required call, now both sides operating personnel can carry out full-duplex communication.Wherein, dial key can comprise station, the place ahead, station, rear, control centre, the place ahead train, rear train etc.
