Existing problems:

1. There is too much noise when the construction equipment is working, so the driver can't hear the information of the train entering the safe construction area told by the walkie talkie in time, and can't stop the construction and avoid the train in time;

2. The on-site safety officer used the whistle to inform the driver, because the noise of construction vehicles was too loud, the driver could not hear the whistle of the safety officer in time, and could not stop the construction and avoid the train in time;

3. The on-site personnel and vehicles can not locate the current location information, which has a great impact on the management and forensics of each transfer.

4. It is unable to dispatch personnel and vehicles in groups; in the construction process, it needs a lot of protective personnel to command and can not effectively solve practical problems, which brings great security risks to the construction process.

Each construction vehicle cigarette lighter or fuse box provides power supply, and the on-board intelligent terminal equipment is installed in the vehicle cab, and a "sound and light alarm" is provided in front of the driver. The safety guard on site and the safety guard of the remote 800 m management are equipped with a 4G handheld terminal equipment. When the train reaches the safe construction range, the remote 800 meter safety guard can hold the 4G hand-held terminal equipment The one key alarm function of terminal equipment controls the start of alarm of sound and light alarm installed in all vehicles on the construction site, and at the same time, it shall make voice call with the site safety guard to inform the safety officer that the train will drive into the safe construction scope; meanwhile, the standby remote controller can be equipped to prevent the equipment from alarming in time due to the poor on-site signal, the on-site guard can carry out remote control by hand The controller controls the sound and light alarm alarm in the construction vehicle to alarm;

To solve the safety of existing line construction and ensure the safety of personnel during construction, specially provide mobile 4gpoc terminal for the remote 800 meter protection personnel and field protection personnel. Based on 4G data service, it can realize real-time intercommunication and video transmission between the remote 800 meter protector and the field guard. Local video and central intercom can be realized. The one key call function can be realized, and the time limit is not limited when the public network is covered The influence of inter and regional, real-time report and view user information, personnel position is reported and synchronized to the dispatching platform through GPS. It can also realize one-to-one, one-to-many real-time intercom calls. The monitoring center platform can call a single user, or call multiple users, and can set up groups to call a single group, and view the real-time location of the caller. Phase The advantages of traditional interphone equipment are: unlimited transmission distance, positioning, transmission of multimedia information such as text expression, voice, video, image, etc., and the rapid circle selection and scheduling of monitoring platform with one key, which is helpful for personnel management
