A common drawback of these devices and systems is the inability to transmit to drivers of non-rail vehicles predictive information on the employment (vacancy) of the crossing due to the fact that the considered analogues use the rail chains of "approaching / removing sections" located directly near the crossing. Moving automation does not allow to provide predictive information for drivers of non-rail vehicles, but only includes light and sound alarms, activates systems that protect the crossing.

This drawback significantly affects the throughput of railway crossings by non-rail vehicles.

The aim of the claimed invention is the formation of an information management system (IMS) of the lower hierarchical level to provide drivers of non-rail vehicles about the employment (vacancy) of level crossings.

The problem is solved in that the information system for early warning of employment (vacancy) of a railway crossing consists of an input module and an alert synthesizer. The input module also includes cellular network subscribers, an Internet site, applications for mobile devices and personal computers. The notification synthesizer also includes an SMS message server and a network of information boards at crossings.

The proposed system includes an information input module and an alert synthesizer and is illustrated by drawings. In FIG. 1 shows the ISO-SP scheme. In FIG. 2 shows a block diagram of a warning about the closure (vacancy) of a railway crossing.

In FIG. 1 is indicated: the central server of the system - 1, the server of SMS messages - 2, the network of information boards at the crossings - 3, the dispatch centralization system - 4, the network gateway - 5, the Internet - 6, the drivers of non-rail vehicles at crossings - 7, the Internet website and applications for personal computers and mobile devices - 8, cellular network subscribers - 9, block of information about the train position - 10, block for short-term forecast of free (busy) moving - 11, block of requests received from drivers of non-rail vehicles through s Internet - 12, SMS-messages received from drivers nerelsovyh transport system - 13, SMS-message system, sent by drivers nerelsovyh vehicles - 14.

In FIG. 2 shows a block diagram of a warning about the closure (vacancy) of a railway crossing, where information blocks are indicated in dotted lines.

The proposed system works as follows.

The information system for the notification of the freedom of railway crossings "ISO-SP" includes visual warning systems in the form of information boards, SMS-service, a set of Internet applications.

All railway crossings in the system must be assigned unique identification numbers of the type ПХХХХХ, where П is the letter denoting the level crossing, and XXXXX is its unique number, for example П13569. Such identification is necessary for the system services to work with consumers.

The central server of the system 1 receives information about the train position 10 directly from the centralized dispatch system 4 through the network gateway 5 according to the network protocol adopted in the system. Here, an analysis is made of the status of transfers connected to the ISO-SP system, and a short-term forecast of their vacancy / employment is generated 11. Central server 1 receives requests 12 from users 7, 8, 9 via the Internet via TCP-IP, in response sending information and forecast 11 for the requested relocation.

SMS server (shot messages service) 2 provides linking of the system with cellular networks. The server is assigned a four-digit short telephone number of the form XXXX, which increases the usability of the SMS service by consumers. The driver of the non-rail vehicle 7 sends an SMS message 13 to a short number with the text ПХХХХХ (moving number). In response, the system sends message 14, which indicates: the move is open or closed and how long it will remain in this state.

When approaching the driveway from both directions, information boards 3 are installed, which contain information 11 about the number of the crossing, its busy / free status, and the estimated estimated time of employment / vacancy. Places of installation of information boards should be selected individually for each crossing, taking into account the peculiarities of building a network of roads, so that the driver of vehicles 7 still at the doorways knew whether he should go further.

To interact with users of ISO-SP on the Internet, a website and a family of Internet applications for personal computers and mobile Internet devices 8 was organized, on which you can find out the number of the desired move, as well as receive a short-term forecast 11 about its condition.

The proposed ISO-SP system will bring significant economic benefits for companies involved in the transport of goods by road, reduce fuel consumption and environmental pressure, and increase driver comfort. The claimed effect of using ISO JV is achieved through the use of information technologies used in rail transport, interaction with the global computer network Internet and cellular networks.
