2 are transmitted to talkback system.
In addition, because needing push-to-talk when saying machine normal use, our main intercom needs to set acoustic control to launch
Module, has the function of that (VOX) is launched in acoustic control.
VOX is introduced：Unlike mobile phone, intercom sends speech and generally requires button transmitting, this key is called PTT
(Push to Hold, push to talk),.If the key is pressed, Splatter Filter and VCO is connected, and otherwise speech can not
Reach transmitting terminal.In order to avoid the worry of long-time button, intercom is provided with VOX (Voice Operation, sound now
Control) function, by VOX, the speech of people can control the connection of Splatter Filter and VCO.
VOX has sensitivity level, and grade is more high sensitiveer.At this time need according to outdoor noise situation, adjust wireless
The alarm sound of alarm host machine matches with VOX susceptibilitys.In general, setting alarm sound, VOX susceptibilitys are minimum i.e. for maximum
Can.
The setting of the function is very big facilitate the system carry out car early warning.
In addition, the main intercom 3 of wireless digital in present embodiment divides for 2 groups, every group is arranged to 2, every nothing
The main intercom 3 of line number word corresponds to the sub- intercom 4 of 5 wireless digitals in same channel, and multigroup main intercom 3 of wireless digital corresponds to frequency
Road is different.The sub- intercom 4 of wireless digital is card insert type wireless digital intercom.
That carrys out car early warning system in above-mentioned existing line construction carrys out car method for early warning, includes the following steps：
Step 1：2 Radio infrared detectors 1 are fixedly secured can be up and down on the base of telescopic movable, and put respectively
In on the curb of the rail track both sides outside 2-3 kilometers of construction part, Radio infrared detector 1 described in adjustment, by Radio infrared
Detector 1 is set above rail plane 10cm to penetrating face；
Step 2：Wireless alarming host 2 is set, memory module 6, memory module 6 are provided with the wireless alarming host 2
Communicate and connect with the signal output module 7 of wireless alarming host 2；Record and carry out car warning message, and warning message is stored in institute
State in memory module 6；
Step 3：The connecting line of earphone wheat and the lead-out terminal in 2 signal output module 7 of wireless alarming host are led to
News connection, so as to export the warning message of recording to the main intercom 3 of wireless digital；
Step 4：The main intercom 3 of wireless digital is provided with acoustic control transmitting module 9, and earphone wheat transmits described
Warning message can trigger the voice control function of acoustic control transmitting module 9, wireless so as to which warning message to be simultaneously sent to more in time
The sub- intercom 4 of numeral；
Step 5：The sub- intercom 4 of more wireless digitals is set at the construction field (site), is worn for construction personnel；The more nothings
Line number word intercom 4 is connected with the main intercom 3 of the wireless digital using same channel communication；
Step 6：Wireless alarming host 2 is opened, basic alarm system is formed with the pairing of Radio infrared detector 1；When distal end
Radio infrared detector 1 detect train by when, send alarm signal, no report from a liner to the wireless alarming host 2 immediately
Alert host 2 exports the warning message recorded in advance to the main intercom 3 of wireless digital by earphone wheat, while warning message triggers
Voice control function, and all more nothings for accessing same channels are passed to by the main car warning message in 3 future of intercom of wireless digital
In line number word intercom 4, realize that car crew's warning function is carried out in distal end.
Above-described embodiment is intended merely to become apparent from that explanation technical scheme makes enumerates, not to the present invention's
Limit, protection scope of the present invention is still subject to scope defined in the appended claims.
