Description

The utility model relates to emergency technological alarms, in particular to universal modular speech informants that respond to two or more different undesirable or abnormal conditions, and can be used for emergency technological alarms, communications and voice alerts about the technical condition of rolling stock and / or technological equipment.

The main tasks to be solved when creating notification devices using voice messages are the following: timeliness of the message; the reliability of the messages issued; system reliability; ability to detect malfunctions of voice communication devices and controlled equipment; ability of devices to notify about malfunctions of responsible persons; the need for binding to existing equipment having various types of output signals;

A wide range of tasks, various applications and working conditions have led to a variety of warning devices operating on the railway network of the Russian Federation.

A device for transmitting information to rolling stock (Voice informant RI-1. Operation manual. DShKA2M3.535.000RE) containing a block of input interfaces connected by a source data bus and a return line with a common control unit; hardware-software synthesizer of ringing and voice signals connected by an 8-bit data bus and a control line with a general control unit; non-volatile storage device connected to the General control unit using two buses and two control lines.

The disadvantage of this device is the lack of a serial interface, which does not allow to increase the warning system with additional matching units.

Also known is a device for transmitting information to rolling stock (RF patent No. 32745, B61L 23/06, 05/12/2003), which contains a block of input interfaces associated with the control unit; hardware-software synthesizer of ringing and speech signals, the input of which is connected via a bus to the output of the control unit; a serial interface, the internal input and output circuits of which are connected to the transceiver of the control unit, and the external ones to the communication line; watchdog timer connected by input and output to the output and input of the control element of the control unit, respectively; a band-pass filter, the input of which is connected to the output of the hardware-software synthesizer of ringing and speech signals, and the output is connected to the input of the low-frequency amplifier; priority block of voice messages included between the output circuits of the interface of the radio station and the connector of the radio station.

The disadvantages of this device include: the technological complexity of increasing the number of received input signals; To flash the ROM of the device, you must use special software and a programmer.

As a prototype, a device for analyzing and generating voice messages for a system of operational voice warning about the position of trains in railway transport was selected (RF patent No. 2291492, G08B 3/10, 07/04/2005). The device includes an input module, configured to convert discrete signals received from the relay control equipment into digital; analyzing these digital signals and issuing a command through a bi-directional bus to the notification synthesizer, configured to store digitized voice messages, select the desired voice message based on the command received from the input module and transmitting the selected message to the radio station and low-frequency amplifier.

The prototype has the following disadvantages: a constant number of received input discrete signals; reprogramming the ROM of a device when changing user requirements causes technical difficulties - a programmer is required, as well as financial and organizational difficulties - direct access to the object is required, usually associated with travel expenses; there is no possibility of simultaneous operation with discrete input signals and digital packets from monitoring equipment, for example, from monitoring equipment for the state of rolling stock.

The objective of the utility model is to develop a universal modular speech informant with a variable number of analyzed input discrete signals from 8 to 256, depending on user requirements; allowing to simultaneously analyze both discrete signals from various control systems, and discrete signals and information packets containing data on the results of control.

The problem is solved in that in the device for analyzing and generating voice messages for a system of operational voice notification about the position of trains in railway transport, which contains an input module configured to convert incoming discrete signals to digital and subsequent transmission of a command corresponding to the current position of trains through bidirectional bus to the notification synthesizer for selecting the corresponding voice message from the permanent storage device and its subsequent th transmission to external devices, the following differences are provided: the composition of the claimed device includes a control unit, made structurally in the form of a separate module. The use of the modular design of the control unit and the bi-directional bus in the inventive device gives a system effect, consisting in the possibility of changing the number of input analyzed signals from eight to two hundred and fifty-six by adding / excluding input modules made according to the same scheme in the form of modular designs.

The control unit includes an Ethernet interface for transmitting data in computer networks; RS232 interface, designed to transfer information between terminal equipment and communication equipment with serial binary exchange; real-time clock in the form of a finished product of a third-party manufacturer (hereinafter: the clock) and non-volatile memory of the event log, which is a storage device with a file system for organizing, storing and naming data (hereinafter: the event log).

The Ethernet interface allows you to exchange data with other network devices and remotely make changes to configuration data.

The RS-232 interface allows you to receive information packets containing data on the results of control from equipment installed on the approaches to stations and artificial structures.

Data received via Ethernet and RS232 interfaces are recorded as events and transmitted by the control unit to the bi-directional bus.

The event log is designed to record information about events for subsequent analysis.

Real-time clocks are designed to record the current time of an event and organize periodic reproduction of messages of an informational, warning or other nature.

In addition, the proposed universal modular voice informant is characterized in that the configuration information of the universal modular voice informant is contained in a text file, which makes it easy to change the device settings, including remotely.

In addition, the proposed universal modular speech informant is characterized in that the storage of the notification synthesizer is made in the form of a storage device with a file system for organizing, storing and naming data. This allows you to create and store a large number of voice messages, and these messages can be changed if necessary without additional equipment, either directly, for example, by replacing a physical memory device, or by overwriting information directly or remotely, via an external network. By changing the configuration text file, you can use ready-made speech phrases as well as make phoneme selection, i.e. at the input module command, the alert synthesizer can generate the desired phrase from a set of phonemes (incomplete phrases and / or individual words).

The utility model allows you to: change the number of input signals in accordance with the requirements of the user; use the device for simultaneous analysis of input discrete signals from various sources; simultaneously analyze discrete signals and information packets containing data on the results of control; to simplify the reprogramming of the device if necessary; save for subsequent analysis statistical data on the input states of the system.

The technical essence and principle of operation of the proposed device are illustrated by the following drawings: figure 1 shows a block diagram of a universal modular speech informant; figure 2 shows a simplified block diagram of a device and its connection with input and output external devices.

The proposed universal modular voice informant includes the following structural elements: input module 1 connected by a bi-directional bus 2 with a notification synthesizer 3 and a control unit 4. Up to sixteen input modules 1 and up to two notification synthesizers 2 connected in a known manner to a bi-directional can be included in the device bus 2.

A universal modular speech informant is made as follows: input module 1 includes four group status polling circuits 5, outputs connected to the inputs of the control processor 6, which is connected by a bi-directional bus 2 to the control processor 7 of the voice synthesizer 2, which also includes a memory card 8, audio decoder 9, relay 10, key 11, the interface of the radio station 12 and the low-frequency amplifier (VLF) 13; and the control unit 4, including the Ethernet interface 14, clock 15, event log 16, RS232 interface 17, is also connected to the bi-directional bus 2 through the control processor 18.

The above-described universal modular voice informant operates as follows.

The input module 1 using the group circuits of the state poll 5 polls the status of the monitoring equipment (see Fig. 2), converts the data into a digital signal and transmits via a bi-directional bus 2 to the notification synthesizer 3 to select the notification signal and to the control unit 4 for recording data in a log 16 and recording the time of occurrence of the event by hours 15. Upon receipt of an information packet containing data on the results of monitoring via the RS-232 interface 17, the control unit 4 writes data to the log 16, recording the time of the event by hours 15 and transmits e about the event through the bidirectional bus 2 to the notification synthesizer 3. When receiving data from any of the sources described above, the notification synthesizer 3, in accordance with the command received by the control processor 7 through the bidirectional bus 2, reads audio files from the memory card 8, generates speech or other for example, a tonal message using an audio decoder 9 and broadcasts it through the interface of the radio station 12 or through the VLF 13. Also, the notification synthesizer sends data to the bidirectional bus 2 on the issuance or non-issuance of a message for Lok Control 4, who, after receiving confirmation from the notification synthesizer 3 generates a report and sends it via the Ethernet interface 14 on the statistics server (not Set schema). The control processor 7 is connected to an electronic key 10 and an internal relay 11 for controlling various types of external VLF and organizing priority switching of signal sources for VLF.

Data received through Ethernet interfaces 14 is also recorded as events and can be transmitted by the control processor 18 via a bi-directional bus 2 to the remaining units of the device.
