Detailed Description
The invention will be further explained with reference to the drawings.
Referring to fig. 1-3, the relay cabinet is connected to the trackside controller and trackside equipment simulation board at both ends, and the trackside controller and trackside equipment simulation board are connected to the PC terminal.
A special line calibration test software program is installed at a PC (computer) end, and can be used for simultaneously collecting and comparing data of the trackside controller and the trackside equipment simulation disk, and controlling the trackside controller to send out a specific command and the trackside equipment simulation disk to simulate the state of trackside equipment.
The trackside equipment simulation board can simulate hardware peripheral equipment of external equipment, can be configured into optional peripheral equipment of a relay cabinet according to specific instructions, such as turnouts, semaphores, shielded gates, external interlocking interfaces, axle counting sections and the like, simulates specific input and output point positions and high and low voltages according to configured characteristics, and simultaneously communicates with a calibration test software program specially installed at a PC (personal computer) end to transmit input and output states.
And a special line calibration test version software program on the trackside controller integrates the information of the related relay control equipment and can acquire the state information of the simulation control panel. And the command is issued to the peripheral equipment of the simulation disk by matching with a line calibration test software program installed at the PC terminal.
The automatic line calibration method of the relay cabinet comprises the following steps:
the method comprises the steps that firstly, a PC side device control simulation disc simulates the change state of the trackside device, and input line calibration inspection is carried out according to the changed state collected by a trackside controller. The input check line is mainly used for acquiring simple input states of trackside equipment (a trackside controller does not control the equipment), such as the state of a shaft counting section, the input state of external interlocking and the like. In particular, the amount of the solvent to be used,
a tester inputs a first test command to a PC (personal computer) end, the PC end controls a trackside equipment simulation disk to simulate trackside equipment to change the state according to the first test command, and the changed state is fed back to a trackside controller through a relay cabinet; the trackside controller feeds back the acquired changed state to the PC end; and the PC terminal compares the acquired changed state with a first command state (input point position of the relay cabinet) in the first test command, if the changed state is consistent with an expected result (all input point position results are normal, wire mixing and misconnection are avoided), and the wiring at the position inside the relay cabinet is correct, the next point position is compared until all point position data are traversed and the comparison is completed, and if the changed state is inconsistent, the wiring is incorrect.
The corresponding external output state of each test command has a unique acquisition state, the logic of the PC end detects that the acquired logic state exists at the moment according to the command state, and if the states are consistent, the internal wiring of the relay cabinet is correct, and if the states are inconsistent, the wiring is incorrect. For example, the state of a switch is moved to location. The corresponding inputs are: the orientation is denoted 1; the inverted bit is represented as 0. The other acquisition states irrelevant to the acquisition are default states.
And step two, the PC controls the trackside equipment simulation disc to simulate the change state of trackside equipment through the trackside controller, and outputs line calibration inspection according to the changed state acquired by the trackside controller. The output check line is mainly used for controlling the trackside controller, and then acquiring the extraction state of the output of trackside equipment and the changed trackside equipment state, such as the state of a control turnout, and controlling the shielding door. In particular, the amount of the solvent to be used,
a tester inputs a second test command to the PC terminal, the PC terminal controls the trackside controller to send a command according to the second test command, the command is transmitted to the trackside equipment simulation disc through the relay cabinet to simulate trackside equipment to change the state, and the trackside equipment simulation disc outputs a recovery state and the changed state is transmitted to the trackside controller through the relay cabinet; the trackside controller verifies whether the instruction is correct or not according to the recovery state; the trackside controller feeds back the acquired changed state to the PC end; and the PC terminal compares the acquired changed state with a second command state (input point position of the relay cabinet) in a second test command, if the changed state is consistent with an expected result (all input point position results are normal, wire mixing and misconnection are avoided), and the wiring at the position inside the relay cabinet is correct, the next point position is compared until all point position data are traversed and the comparison is completed, and if the changed state is inconsistent, the wiring is incorrect.
The recovery state is the verification of the command, for example, a command is sent to drive the relay, and the trackside controller simultaneously collects the front section and the rear section of the relay to verify the correctness of the command sent by the trackside controller.
To sum up, the correctness of the internal connection line of the relay cabinet is the basis for performing the trackside function control, in the prior field test process, the function point positions of the input and the output of hardware need to be tested and verified one by one, which usually consumes huge manpower and material resources and consumes very long time. In the invention, preferably, before the relay cabinet is installed (including after the trackside controller is installed), the relay cabinet is delivered from the factory so as to assist the relay cabinet manufacturer in carrying out the line calibration test of delivery inspection. The main purposes are as follows: 1) the whole relay cabinet is in a state of completing installation, real input and output tests beside a rail can be carried out, 2) if problems are found, design and installation of the relay cabinet can be modified timely, the relay cabinet is prevented from being sent to a field, and installation or modification of design problems can be avoided in the field testing and line checking processes.
The above embodiments are provided only for illustrating the present invention and not for limiting the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and therefore all equivalent technical solutions should also fall within the scope of the present invention, and should be defined by the claims.
