Description

The invention relates to automated control systems for the running gear of rolling stock cars, is intended to automate the process of recording and transmitting data on the status of cars in a train to an automatic workstation of a car maintenance center when the train meets immediately, and is based on visual inspection and fixing via the remote control visible malfunctions of the rolling stock passing through the control section.

A device for monitoring the running gear of wagons, namely, the skew angle of a pair of wheeled trolleys of freight cars, is known on the move.

A device for determining the skew angle of wheel pairs of freight wagon trolleys contains three inductive sensors (D1, D2, D3), fixed with a bracket to the rail sole. When the wheel flange passes over the sensor housing, the value of the coil inductance changes, which is fixed by the electronic circuit to which the sensor is connected. The microcontroller of the device determines and stores in the memory the value of the skew angle for each wheel pair that has passed over the sensors. According to the sensor signals, the microcontroller determines the distance between adjacent wheelsets. By a special algorithm, recognition of the types of moving units in the composition is carried out according to known distances between adjacent wheelsets. The serial number of wagons in a train and the numbers of wheelsets in a car for which an excess of the threshold value of the skew angle of the wheelset (RF patent No. 2323844, IPC B61K 9/00, publ. 05/10/2008, - prototype).

A disadvantage of the known solution is the inability to control such malfunctions of the rolling stock as complete or partial unloading of the wheelsets, which leads to a decrease in traffic safety and the inability to eliminate this malfunction of the rolling stock when the train stops at the intermediate station.

The technical result, to which the claimed invention is directed, is to expand the functionality of the system and increase the safety of rolling stock by increasing the reliability and reliability of the process of registering and transmitting data on the condition of cars in a train by performing visual inspection and fixing through the console of visible malfunctions of the rolling stock passing through the control section.

The specified technical result is achieved by the fact that the automated monitoring system for the running gear of the wagons containing inductive sensors mounted on the rail, detecting the passage of wheelsets, contains the automated workstation of the wagon inspector (ARNX) connected by cable lines when the train meets “immediately”, the controller unit and the wagon inspector panel located in the zone of installation of sensors, the unit is a station and electronic computing device with which the workstation is equipped Dr. arrival park.

The system is characterized by the fact that inductive sensors can be mounted on the sole of the rail with brackets.

The invention is illustrated in figure 1, which shows a diagram of the automated location of the inspector of the wagons at the meeting of the train "immediately".

The inventive system contains:

- outdoor equipment: inductive sensors 1, 2, and 3, for example, ID-D2, wheel pairs, mounted on rail 4 of the control section using brackets, perform the function of reading devices (counting axles of wheel pairs, recognizing types and number of moving units in the composition) ;

- a controller unit BK-ARNX 5, placed in a standard transformer box 6 near the installation site of the sensors, - switching equipment for processing signals from inductive sensors and transmitting data to the station unit BS-ARNX 7;

- on-site equipment: the inspector’s console PO-ARNX 8, located in the inspector’s room or under a canopy near the sensor installation site, - 9 buttons are located on the front panel of the inspector’s console, which allows you to enter codes from 1 to 9 with the coding of various faults assigned in advance;

- station block BS-ARNX 7, located in the premises of the operator of the arrival park 9, - switching equipment for receiving data from the BK-ARNX controller block and communication with PC 10 of the IBM PC type of the PTO operator;

- PC type 10 IBM PC for the equipment of the workstation (AWP) of the operator of the park of arrival and cable lines 11.

When working with ARNH, the inspector does not count the number of the inspected car. ARNH is located in front of the arrival parks on the main tracks or directly in the arrival park.

ARNH system functions:

- calculates the number of axles from 2 to 16 for each car;

- determines the type of car (freight, passenger, locomotive);

- determines the number of the car from the head of the train and the number of cars in the train from 1 to 400;

- determines the number and number of axles from 1 to 6400;

- determines the length of the train from 10 to 6000 m;

- measures the speed of a train following a checkpoint from 1 to 150 km / h;

- determines the serial number (up to 999) of the controlled structure that has been proceeding in this direction since the beginning of the day;

- fixes the car malfunction code entered by the inspector when the car passes through the control section:

- transmits the results of the inspection over the communication line and displays them on the display of the station unit or operator workstation;

- if there is a connection with the ACS systems, it automatically binds to the inventory number of the car, transfers the results of the inspection to the ACS systems and archives the results of the inspection.

Depending on the speed of movement of the rolling stock through the control section, the ARNH may have different designs of remotes designed to equip the inspector’s workplace. Structurally, the equipment differs only in appearance and number of buttons on the inspector’s remote control.

One of the ARNH versions is designed to equip security posts at wagon technical maintenance points (hereinafter referred to as VET), as well as in passenger station parks. There are 9 buttons on the front panel of the inspector’s panel, which allows you to enter codes of 9 different faults at a relatively low speed of the rolling stock through the control section.

Fault codes: 1 - wheelset; 2 - axle box; 3 - body; 4 - trolley; 5 - shock-traction device; 6 - a brake; 7 - frame; 8 - roof; 9 - negative dynamics.

Another embodiment is designed to equip security posts on the hauls to identify cars with negative dynamics and other malfunctions. Since the speed of the rolling stock is quite high (more than 60 km / h), the inspector enters one of two possible codes when passing the car through the control section. Accordingly, on the inspector’s remote control there are two larger buttons. Possible codes are wagging (or side roll) and galloping.

An automated system for monitoring the running gear of wagons with an automated workstation for a wagon inspector when meeting a train “immediately” works as follows.

Three inductive sensors 1-3 are mounted on the rail using brackets (without drilling holes) and are connected via cable couplings M1 and M2 to the BK-ARNH unit located in the standard TY1 transformer box. Also, the inspector's console PO-ARNX, a 220 V, 50 Hz power cable and a communication line with the premises of the arrival park operator are connected to the BK-ARNH block. The length of the connecting cable between the BK-ARNX unit and the PO-ARNX control panel is not more than 50 m. The power supply of the PO-ARNX control panel and signal transmission are carried out on one cable. As a communication line with the premises of the operator of the arrival park, a physical communication line or a dial-up tone-frequency channel with a two- or four-wire termination can be used. For communication, modems built into the BS-ARNX and BK-ARNX blocks are used. Protocol modulation of signals in the communication line V23.

In the absence of a train, the BK-ARNH unit continuously performs balancing of inductive sensors 1, 2, and 3. When the train enters the monitoring section, the balancing stops. When each axis passes over the inductive sensor, a positive polarity pulse of 5 ms duration is formed at the output of the corresponding channel. The pulses are fed to the input of the controller, which performs their calculation, measuring the time intervals between pulses and storing the received data in RAM memory. In addition, the controller continuously receives signals from the PO-ARNX console via the serial port via the RS485 interface. The controller controller PO-ARNX continuously monitors the pressing of buttons located on the front panel of the console. When a pressed button is detected, the controller transmits its code (which is actually a malfunction code) via the serial port. When a byte is received through the serial port, the controller of the BK-ARNX block also stores it in RAM along with the current value of the counter of the number of axes for the sensor 1. After the train leaves the monitoring section, the BK-ARNX block processes the data stored in the RAM. As a result of processing, recognition of the number and types of moving units in the composition is performed. After that, the axis number corresponding to the moment of receiving the byte with the fault code is converted to the car number (excluding the number of locomotives). Next, an array of data is formed containing general information about the train and information about the fixed malfunctions. The specified array is transmitted via a communication line to the BS-ARNH unit located in the station duty room. After receiving the array, the information is displayed on the liquid crystal (LCD) indicator of the unit. If a PC is connected to the BS-PB unit, then the received array enters the PC using the PC COM serial port.

About 10-15 seconds after the train leaves the control area, the following line appears on the LCD indicator of the BS-ARNX unit: dd / ms / yy hh: mn mm lock 11 + vv wag. total axes xxx, where:

dd / ms / yy hh: mn - current date month year hours and minutes respectively;

mm lock - serial number of the train passing through the control section;

11 - the number of locomotives in the train;

vv - the number of cars in the train;

xxx is the total number of axles in the train.

In the lower lines of the indicator of the BS-PB block, information on malfunctions of the rolling stock for each car is displayed.

Each line displays information on one faulty car in the following form: vv-d-name,

where vv is the train number in the train (excluding locomotives);

d - malfunction code (digit from 1 to 9);

name - type of malfunction.

For example, the appearance in the bottom line of information “23-1 - negative dynamics” means that during a visual inspection of the car 23 (excluding locomotives), the inspector pressed button 1 on the remote control. It is known that code 1 corresponds to a “negative dynamics" malfunction, i.e. this car must be thoroughly inspected and repaired at an intermediate station.
