Highway intercom solution
First, the system profile
HM-PTT is an intercom voice service system based on wireless data network (CDMA-1x or EVDO network) implemented by VoIP technology. It is different from traditional walkie-talkie. There is no restriction on distance. As long as there is wireless network, , Is the traditional cluster communications products extension and supplement.


The system is based on the public network - easy to achieve nationwide intercom

Second, the system advantages
1, a press that pass

Mobile phone into a walkie-talkie, call fast, support single call and group call.

2, a call should be

Group users within the large capacity, group calls, for on-site command, on-site coordination of the work scene.

3, super cover

Free from geographical, distance restrictions, can achieve remote real-time scheduling.

4, professional scheduling

Multi-function dispatcher, to meet the daily needs of the Group's customers in the scheduling of professional requirements.

5, speak management

To achieve sub-authority forced to insert the speech, give priority to emergency instructions.

6, the network is simple

Relying on China Mobile's communications network, only need to increase the PTT server can achieve PTT system.

7, interoperability

Through the installation of intermediate converters, you can communicate with other intercom systems and other cluster systems.

Third, the system function
1, the basic business functions

Fixed group calls

After entering a fixed group, the user can make calls to all online users in this group, and can also receive calls from other users in the group.

Dynamic group establishment

Users can initiate invitations to one or more online users to create dynamic groups for calls.

 User status display

In the client software can see each group in the group is online, a valid call.

 call tips

During a cluster call, the user participating in the call can receive various prompts related to the cluster call status.

 seize the call

In the same group, when multiple people make a call, in the case of the same call authority, call the right to speak, the remaining users to answer the state.

 users multiple groups

Users can view multiple groups of members, you can enter multiple groups to call.

Default group

The default group is the group that the user automatically enters after landing, and each user can specify a default group.

 dropped and automatically reconnected

When the data network is broken for some reason, the software will detect whether the network is available, and when the network is available, the software will re-dial the connection.

2, the system special features

 User call priority

The user has the call priority, and the administrator can set and modify the priority of the user's call. In the same group, when a user with a low priority is on a call, the user with the highest priority can interrupt his call at any time and make a call.

 recording playback

Users in the scheduling and management platform can query each group of speech records, and can play back each record, in the enterprise management platform can query all the call records in the enterprise.

 monitor

The user can listen to multiple groups at the same time.

 broadcast

The dispatcher can broadcast all the groups in its enterprise.

3, multi-function scheduling table

 plug in

The dispatcher can be forced into any group of intercoms.

 demolitions

The dispatcher can force users to leave a group.

 remote death

The dispatch station can remotely "shut down" the terminal's cluster functionality.

 call

The dispatcher can make a single call and group call to the user.

 visual scheduling

Set the phone, personnel positioning, cluster intercom as one.

Fourth, contrast with other intercom
HM-PTT intercom and other intercom way to contrast, to put the traditional digital intercourse in Qingdao as an example:

Fifth, the highway industry applications

1, the solution map


To meet the current highway centralized management model development, to solve the toll station monitor, webmasters and management center long-distance, cross-regional daily and I should be anxious to talk about the issue to meet the needs of the new era of fee-based operations; Road traffic, rescue, traffic police and monitoring center emergency communication and speaking of the problem, to improve the road section of the emergency response speed and disposal capacity. The use of wireless cluster intercom can be a comprehensive solution to the highway cross-regional, multi-sectoral, large-scale rapid communication and reporting problems.

2, the group structure chart


Combined with the actual management structure of the highway and the characteristics of the application, the establishment of the whole section of the management structure of the charge management group and emergency management group, the charge management group can administer a number of toll station group to achieve the toll station within the group communication and monitoring center communication The Emergency management group can be under the jurisdiction of the road, rescue, traffic police and other intercom groups to achieve different communication within the intercom group, and monitoring center communication. According to the need to set the walkie-talkie can choose to enter other groups in the intercom, to achieve a more flexible call and emergency communication.

3, monitoring center

In the monitoring center to install two walkie-talkie, one to charge management group management; one to emergency management group, two can hear the charge management group and emergency management group call content, monitoring center of the radio to speak All the groups under the jurisdiction of all can hear the speech, to achieve the whole section of all emergency communication and management.

According to the needs of the road, you can set up a number of central management group, to achieve the management of the district. Walkie-talkie can choose to enter other groups to launch a small range of intercom, to improve the response speed of response and disposal capacity.

4, toll station

In the toll station monitor, webmasters, electricians and other staff of the configuration of the walkie-talkie, to achieve the internal communication intercom, all communication content monitoring center can be collected from the default intercom management group intercom, but also direct call and monitoring center Communication and speaking, to achieve this site and the monitoring center of the two intercom.

Webmaster walkie-talkie can be selected according to the need to enter the higher charge group, emergency group initiated intercom, to achieve a more flexible, more extensive call and emergency communication, improve the response speed of response and disposal capacity.

5, road administration, traffic police

For the whole road patrol road administration, rescue, traffic police and other personnel configure the walkie-talkie, to achieve communication within the department intercom, all communication content monitoring center can be collected from the default intercom management group radio, but also direct call and monitoring Center to communicate intercom, to achieve the department and the monitoring center of the two-level intercom.

Road, rescue, traffic police walkie-talkie can be selected according to the need to enter the higher charge group, emergency group initiated intercom, to improve the response speed of response and disposal capacity.
