Description

The utility model relates to railway transport, in particular to devices that monitor the status of locking and sealing devices with electronic seals.

For sealing wagons and containers, disposable (mainly mechanical) locking and sealing devices (ZPUs) are used, which are hung on special units for locking closed-type wagons (covered wagons, tanks, refrigerated wagons, hopper wagons, and others), the designs of which cannot withstand criminal mechanical exposure.

Currently, designs of locking and sealing devices with electronic seals have been developed in railway transport, which provide: locking (fixing a closed state) (for example, a tank manhole cover), sealing with an electronic seal and a manual control device (programming sealer); fixing the electronic seal in the body of the locking and sealing device during sealing.

Known devices of a similar purpose, in which the control of locking and sealing devices is carried out by means of fixed cameras for general and detailed inspection (RU 2138077 C1, 09/20/1999).

A disadvantage of the known device is the inability to carry out highly effective and reliable automated control of devices for locking a car with an electronic seal, since it cannot control the information entered into the device for locking.

The technical result of the proposed utility model is to enable effective and reliable automated

control devices for locking the car with an electronic seal.

This technical result is achieved due to the fact that the complex for automated control of a device for locking a car with an electronic seal contains a device permanently mounted on the carrier frame on at least one side of the rail track and above it for reading previously entered information from the electronic seal of the moving a wagon and a wagon count sensor, wherein the devices for reading information are configured to automatically turn on and work when a train passes through a place and installation.

If earlier the sealing and locking functions were concentrated in one removable mechanical or electronic switchgear, then in the considered switchgear the locking function is assigned to a reliably protected electronic-mechanical unit for locking and sealing (EMU), and the sealing function is fixed to a removable electronic seal (EP), which is fixed in the EMU housing, which is an integral structure mounted permanently on the tank lid and allows not only to reliably protect the electronics, but also successfully solve the problem associated with rientatsiey transmitting device and thereby improve the reliability of information transmission.

Used only once and introduced into the body of the EMU electronic seal (EP) is protected by its design from criminal mechanical stress.

The locking system of a car with microelectronic sealing consists of the following technical means:

- electronic-mechanical unit locking the car (EMU);

- electronic fillings (EP);

- manual control device (RUU) - programming sealer;

- stationary reading devices (SSU) - devices for reading information.

In turn, the EMU consists of a mechanical unit that locks the lid of the tank door (door of a covered or refrigerated car, a hatch of a hopper car), an electromechanical block that seals and locks the mechanical block from unauthorized opening of the lid of the tank lid (door of a covered or refrigerated car, hatch of a hopper car), an electronic unit that controls the operation of the components of the EMU and the exchange of information with the electronic switchgear, RUU, SSU and the antenna unit to ensure information exchange between ME and FL, ruu, SSA.

The design of the EMU for tanks is a monoblock non-separable design consisting of a housing and a screw. The lower part of the body is a nut that fixes the bolt of the lid of the loading door of the tank by tightening it with a screw. EMU provides:

- locking (fixing the closed state) of the tank hatch;

- filling the tank with the help of electronic devices and RUU;

- fixation of the EP in the EMU housing during filling. EMU has the following conditions:

- "Sealed" - the EMU is serviceable and closed, the electronic actuator is installed;

- “Intact and unsealed” - EMU is intact and not closed, ES has not been installed;

- “Faulty” - the EMU is faulty (closed or not closed), the electronic drive is installed or not installed.

EMU when sealing provides reliable fixation of the EA in the mechanical unit. When removing an electronic seal, the EMU automatically transmits a command to it that blocks further recording, making changes, or erasing information previously recorded in the electronic signature. That is, this information cannot be changed and remains available only for reading. EMU also ensures the inability to reuse EP.

When remotely monitoring the presence and condition of the locking node, the EMU provides the following information to the SSU:

- car number (8 digits);

- date and time of sealing (8 digits - month, date, hours, minutes);

- RUU number with which sealing was made (4 digits).

To ensure the possibility of investigating cases of unsafe transport or emergency situations, the same information about the last 5 operations of sealing and removal of electronic components is stored in the electronic control unit and can be read using the RUU in the following volume:

- control number of electronic signature (7 digits);

- the state of the EMU (“Sealed”, “Serviceable and Unsealed”, “Faulty”) - 3 bits;

- date and time of sealing (8 digits);

- the last digit of the year of issue of electronic signature (1 digit);

- date and time of removal of electronic signature (8 digits);

- RUU number, with the help of which:

sealing (4 digits) removal of electronic signature (4 digits).

EMU provides information transfer to the SSA in the allowed international frequency range of 865 ... 869 MHz by changing the reflection coefficient of the radio frequency signal transmitted from the SSU.

EMU is operable at extreme operating temperatures from -60 ° C to + 65 ° C. The upper value of the relative humidity of 100% at +25 degrees C.

The EMU uses a power source that ensures the operation of the EMU without replacement for 11 years.

EMU and SSU provide remote reading of information at speeds of controlled train composition up to 80 km / h in any direction of movement.

The service life of the EMU is at least 10 years. EMU does not require any maintenance during its service life.

RUU stores information on 260 sealing or unsealing operations. The information contained in it is transmitted to a computer with subsequent use for processing transportation and technological documentation or for further transfer through SPD to the ACS of the station.

SSU automatically turns on only during the passage of the composition. SSU operates at a distance of 1.5 to 8 meters from the EMU readable cars.

Radio emission comes only from SSU. EMU - a passive device that provides information to the SSU.

The complex works as follows.

At the departure station, the process of sealing the wagon (tank) is carried out.

After the electronic seal (EP) is inserted into the body of the electronic-mechanical unit (EMU), a manual control unit (RUU) is installed in a special lodgement on the upper part of the body, which, by pressing a button on it, transfers its identification number, date, time and command to the EMU "Start publicizing."

The EMU receives this information and the command, polls the number of the electronic contactless contact and automatically checks whether this seal has been used before or not. When confirming the non-use of the seal earlier, the EMU records additional information in the EP: the number of the car and the number of the RUU, which is sealed, the date and time of sealing.

After that, the EMU issues a command to fix the electronic actuator in the EMU housing, after which it is possible to remove the seal from the EMU housing only by the command of some RUU.

Manual control devices (RUU) are used to equip departure stations along the route (at the control points - FFP) and destination stations (one each for a shift of workers associated with sealing, unsealing the wagons when receiving, delivering goods and en route).

The sealing process is completed by transferring information from the EMU to the RUU about the number of the sealed car and the number of EP. Accounting for a car’s sealing operation is carried out by “transferring” information from the RUU to a computer for subsequent processing of transportation and technological documentation or transfer via SPD to the station ACS.

On the way (at the FFP), the state of the EMU and the EF is automatically controlled through a stationary reading device (SSU), the placement of which is most effective on the supporting frame of the system for the commercial inspection of trains and wagons (ASKO PV). In this case, the SSA is turned on only for the duration of the train passing through the “gate” of the ASKO PV.

Considering that opening the hatch covers of tanks equipped with EMU is practically impossible without destroying the hatches, access to the cargo is possible only with the help of the RUU. Unauthorized use of RUU for criminal purposes is an emergency.

In the event of an emergency related, for example, to the unauthorized use of any RUU (stolen from a station employee or by deliberate conspiracy with him) to unseal and open the car in order to steal cargo from it, the SSU will receive information from the EMU about the RUU number used for such sealing, date and time of its unauthorized use. The use of this information by law enforcement agencies will significantly accelerate the process of identifying a criminal.

At the destination station, after the RUU is installed in the EMU cradle and the button is pressed, information is transferred from the RUU to the EMU about the RUU number, date, time, and also the “unzip” command. After this, the EMU records the received information in the electronic drive, which is released from fixation and is removed from the housing of the electromagnetic drive.

If facts of unauthorized use of any RUU along the route are detected at the destination station (as described above in the “on the way” stage), the wagon is unloaded in the established manner

okay. Moreover, the information from the EMU about the date, time, number of the RUU used for unauthorized opening is also the evidence base in the investigation of the unsafe transportation.

The proposed utility model will allow the possibility of effective and reliable automated control of devices for locking a car with an electronic seal.
