At the control point, transceivers of the first and second channels, a code converter, a matching unit, an encoding unit, an information processing unit are installed (RF Patent No. 2160929, CL G 08 G 1/01, G 08 G1 / 123, publ. 2000.12.20).

The disadvantages include the low level of noise immunity of transceiver paths between route sensors and vehicles, the inability to simultaneously transmit and receive information from several vehicles to a control point.

A known method of controlling the movement of land transport, comprising route sensors, a central control room with a two-channel transceiver and moving units, a traveled sensor, a transceiver, a control unit, a digital-to-analog converter, a speech input-output unit, an indicator of deviation from the schedule. The central control center monitors the location of all vehicles on the route in the "Request-response" mode, alternately sending codes on the first channel, each of which contains the starting package, vehicle number code, deviation from the schedule and a voice call command. In response, the vehicle either transmits a response codegram containing a marker code, a location code, and a voice call command through the first channel, or receives a codegram from one of the route sensors in the coverage area of which it is located via the third channel. After receiving the response vehicle codogram to the central control room, the location of the corresponding vehicle on the route is determined and the current time is recorded during the exchange of information. If the vehicle receives a voice call command on the vehicle, an audible alarm sounds if the signals from the tangent sensors and the tube holder correspond to the lowered position of the telephone handset on the vehicle, and the driver negotiates with the dispatcher over the telephone via the second transceiver channel. After the communication session, the dispatcher generates a reset command (RF Patent No. 2108625, CL G 08 G 1/01, publ. 1998.04.10).

Disadvantages: the lack of emergency buttons, notifying passengers of the next stops, the time of arrival of the vehicle, insufficient noise immunity of the transceiver paths between the vehicle and the control point.

The closest in technical essence and the achieved result to the claimed one, is a system for monitoring the movement of vehicles, containing a central control center, a server combined with automated workstations of operators in the local area network, devices of automated control points containing a microcontroller connected with a transceiver, vehicle devices, each of which contains a microcontroller connected to a digital-analogue and analogue o-digital converters, a block of indicator signals and a panel of signal buttons. (RF patent No. 2113014, class G 08 G 1/01 publ. 1998.06.10).

The disadvantage of the system is the need for the driver to be distracted by a telephone conversation when receiving additional information, only one operator has the ability to call the telephone at the central dispatcher, the polling of control points is carried out in a cyclic mode, which does not allow the simultaneous exchange of information between several control points and the central control center.

The task underlying the proposed technical solution is to expand the functionality of the system, improve the quality of control due to the ability of each operator of the central control center to simultaneously communicate directly with drivers of vehicles independently of each other, and the possibility of the driver receiving textual information (discrete message) , unification of the method of exchange of information between the checkpoint and the central control room.

The problem is solved as follows. Into an automated dispatching system for monitoring and control of road transport, containing a central dispatching station, a server combined with automated workstations of operators in a local area network, devices of automated control points, each of which contains a microcontroller connected to a transceiver, and transport devices means, each of which contains a microcontroller connected to digital-to-analog and analog-to-digital converters, a unit indication signals and a remote control of signal buttons, according to the proposed technical solution, the microcontroller of each vehicle device is connected to a discrete message output unit, an automatic sound informing unit, a digital-to-analog converter connected to a low-frequency amplifier and an analog-to-digital converter connected to a microphone amplifier, while the microcontroller of the devices of automated control points is connected to a radio modem module, an electronic display and a program and a storage device, the central control room server being connected to a modem module, paper output device, operator workstations containing personal computers, each of which is connected to analog-to-digital and digital-to-analog converters, which, in turn, are connected to an amplifier low frequency and microphone amplifier respectively.

A new technical result is that the exchange of data between devices of automated control points (UACP) and the central control center (DAC) is carried out using radio modem modules installed on each UACP connected to the microcontroller and a modem module on the DAC connected to the server via Internet protocol, which allows for independent simultaneous exchange of information (receipt of information in the "real" time mode), a microcontroller of vehicle devices (TCB) is connected to a discrete message output unit that allows text messages to be output to the TCB and an automatic sound informing unit to notify passengers about stopping points, the UACP microcontroller is connected to a programmable memory device that stores the stopping point number, a discrete message transmitted to TCB, as well as connected to an electronic display installed at stopping points and serving to reliably inform passengers.

The sensors installed on the TCB send their codogram only after the vehicle is in the zone of operation of the automated control point and the request for permission to send from the UAKP, which practically eliminates the effect of noise interference in the city from vehicles in the case of a city-wide project and a large number of vehicles .

To inform passengers at the stopping points, an electronic display is installed.

Passengers are notified of the next stopping point using the automatic sound informing unit, without distracting the driver.

The transmitted discrete messages from the DAC are displayed on the TCB and may contain any textual information.

Communication between the driver of the vehicle and the DAC operator is through a two-way speakerphone.

In case of hostage-taking or hijacking of a vehicle, alarm signals are received by each control point in the direction of the vehicle, which allows you to control and predict the route of the vehicle; if it is necessary to call an ambulance, police, Ministry of Emergencies or technical assistance, the driver has the opportunity to call these services directly from the TCB, while in the area of operation of the UAKP.

Thus, the listed set of features in comparison with the prototype allows you to expand the functionality of the system, improve the quality of dispatch control of ground routed transport and reduce the time required to assist passengers and the driver in case of emergency.

The possibility of using the inventive automated dispatching system for monitoring and control of road transport allows us to conclude that it meets the criterion of "industrial applicability".

The invention is illustrated by drawings: figure 1 shows an automated dispatch system for monitoring and control of road transport; figure 2 shows the TCB; figure 3 shows the UAKP; figure 4 shows the DAC.

Automated dispatching system for monitoring and control of road transport (see figure 1), including: TCB (see figure 2), containing the transceiver module 1, connected to the microcontroller 2, connected to the output unit of discrete messages 3, block indication signals 4, a control panel 5, an automatic sound informing unit 6, a digital-to-analog converter 7, an analog-to-digital converter 8, connected to a low-frequency amplifier 9 and a microphone amplifier 10, respectively. The UAKP device (see Fig. 3) contains a transceiver module 11 and a radio modem module 12 connected to a microcontroller 13, to which an electronic board 14 and programmable storage device 15 are also connected. The DAC (see Fig. 4) contains a modem a module 16 connected to a server 17 to which a device for outputting information on paper 18 is connected, as well as automated workstations of operators (AWPs) 19 (1) ... 19 (n), each of which contains a personal computer 20 (1) ... 20 (n) connected to digital-to-analog conversion with an element 21 (1) ... 21 (n), an analog-to-digital converter 22 (1) ... 22 (n) connected to a low-frequency amplifier 23 (1) ... 23 (n) and a microphone amplifier 24 ( 1) ... 24 (n), respectively.

The work of the system of automated dispatch control and management of road transport is as follows. The TCB 2 microcontroller generates the unique code of this TCB programmed into it. From microcontroller 2, the codogram is sent to the transceiver module 1, which on the TCB will work in standby mode.

The connection between the TCB and UAKP occurs by searching in a certain frequency range of the channel with lower noise interference components, the exchange of information between the two modules is carried out by the packet transmission method, which allows the transmission of information in both forward and reverse directions.

UAKP includes: transceiver module 11 - a device similar to that located on the TCB, but operating in a request and wait for a response. After establishing a connection between the TCB and UAKP with the TCB, a unique vehicle code is transmitted. Upon completion of the transfer, the information will be processed and verified in the microcontroller UAKP 13, if the positions of the beginning and end of the sending from the microcontroller 13 are correct, the signal transmits correctly to the transceiver module 11, which in turn is sent to the TCB. The UTC 1 transceiver receives a signal and sends it to microcontroller 2. After these processes have passed, the microcontroller, having received a signal on the correctness of receiving the transmitted information in the coverage area of this UAKP, shuts off until the next UAKP.

The message received at the UAKP with the TCB arrives at the radio modem module 12, from where, through one or another operator providing services of third-party communication operators, it arrives at the modem module of the DAC 16. The modem module of the DAC 16 will be connected to the switch of the cellular operator to which the information is received from all UAKP. Next, the DAC receives all incoming information, processes it and records it on server 17 (it will store information about the time the message was received and the messages themselves received from the TCB, it also processes the received information and distributes it). Information processing is carried out by the DAC operators 19 (1) ... 19 (n), as well as in automatic mode. The device for outputting information on paper 18 is a printer and is used to output text information.

The discrete message transmitted by the dispatcher arrives at the UAKP, where it is stored in ROM 15 until the TCB falls into the coverage area of the UAKP. The message will be transmitted to the TCB and displayed on the discrete information output unit 3. After confirming the receipt of the information, the microcontroller 13 deletes it from the ROM 15. The message generated automatically in the DAC about the imminent arrival of the vehicle at the stopping point is sent to the UAKP modem module, then to microcontroller 13, from the last it gets to the electronic board 14. When passing a vehicle equipped with a TCB, a stopping point from the microcontroller, a stopping station number signal is stored on the TCB, storing located in the ROM 15, and transmitted through the transceiver module 11. The transceiver module UTS 1 receives the signal and transmits it to the microcontroller 2. Having recognized the signal, the microcontroller 2 sends it to the automatic sound informing unit 6, where the desired audio file will be played. The signal from the control panel 5 through the microcontroller 2 and the transceiver module 1 through the UAKP is fed to the DAC, where it will be displayed on the operator's workstation, which will decide on a call to a particular help point. Analog-to-digital 7 and digital-to-analog 8 converters connected to low-frequency amplifiers 9 and microphone amplifiers 10 provide two-way communication with operators 19 (1) ... 19 (n) of the DAC. Each workstation of the operator 19 (1) ... 19 (n) is equipped with a personal computer connected to the digital-analog 21 (1) ... 21 (n) and analog-to-digital 22 (1) ... 22 (n) converters connected with low-frequency amplifiers 23 (1) ... 23 (n) and microphone amplifiers 24 (1) ... 24 (n), which provide two-way communication with drivers of vehicles.

Thus, the advantages of the proposed automated dispatch system for monitoring and control of road transport is as follows:

- the use of a discrete information output unit, an automatic sound informing unit, analog-to-digital and digital-to-analog converters connected to a low-frequency amplifier and a microphone amplifier, respectively, as part of the TCB, will make it possible to increase the driver's information without distracting telephone calls and announcement of stopping points, the possibility of driver conversation with the DAC operator without using the telephone handset, which together will lead to a reduction in emergency situations;

- the use of an electronic scoreboard at stopping points will provide passengers with information about the arrival time of the next transport.

- the use of a radio modem module as part of the UACP and a modem module as part of the DAC using third-party services of telecom operators will allow the simultaneous exchange of information without delays between the UTS and the UACP with the DAC;

- the use of personal computers of automated workstations of operators, each of which is connected to analog-to-digital and digital-to-analog converters connected to low-frequency amplifiers and microphone amplifiers, respectively, will allow each operator to call and conduct a voice communication session with drivers of vehicles independently of each other.
