[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] In this application, the terms "comprises", "comprising" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element.

[0035] It should be noted that the blocking equipment mentioned in this plan specifically refers to: equipment used to handle train blocking; the blocking equipment must ensure the implementation of the basic principle that only one train is allowed to occupy a section at the same time.

[0036] Block equipment is a section signaling equipment used to ensure the safe operation of trains within the section and improve the section's throughput capacity. It is mainly divided into automatic block, automatic station-to-station block and semi-automatic block.

[0037] At present, both automatic station-to-station blocking and semi-automatic blocking rely on relay circuits. Specifically, semi-automatic blocking is mainly implemented using 64D relay circuits; automatic station-to-station blocking introduces axle counting as the section track condition based on the 64D relay circuit, and superimposes some logic circuits to realize automatic handling, automatic approval and automatic confirmation and recovery of trains.

[0038] However, the above two blocking methods have the following shortcomings in practical application:

[0039] 1) Poor scalability, less information transmission content between stations, and inability to implement inconsistent blocking mode checks between two stations;

[0040] 2) The existing relay interlocking circuit has timing problems caused by resistance and capacitance failure, which affects the availability of the interlocking system;

[0041] 3) The blocking system is designed to be non-redundant. Failure of a single component will cause system failure and affect the reliability of the blocking system.

[0042] 4) Monitoring is not perfect and faults are difficult to locate.

[0043] To solve the above problems, this solution proposes a semi-automatic blocking and automatic station-to-station blocking system to solve the problem of resistor-capacitor failure, revise the station-to-station transmission conditions to realize the inconsistent blocking mode check in the automatic station-to-station blocking mode, and design the whole system redundantly to increase the system reliability. A monitoring unit is set up to locate the fault to the board level. The following describes this solution in detail through various embodiments.

[0055] In some specific embodiments, in combination Figure 3 , see Figure 4 , Figure 4 Another structural block diagram of a semi-automatic inter-block system and an automatic inter-station inter-block system provided by an embodiment of the present invention is shown.

[0059] Specifically, the sensors of the axle counting host unit 100 are deployed outdoors, and the other parts of the axle counting host unit 100 are deployed indoors.

[0060] The above embodiments of the present invention Figures 1 to 4 , is a related explanation about the semi-automatic block and automatic station-to-station block system, which realizes semi-automatic block and automatic station-to-station block through computer-based axle counting host unit, block host unit and communication unit with redundant design, improves the availability and reliability of the block system, and sets up a monitoring unit to locate faults to the board level.

[0061] In order to better explain the specific structure of the above-mentioned semi-automatic block and automatic station-to-station block system, the following Figure 5To illustrate the specific structure of the semi-automatic block system and the automatic station-to-station block system as a whole;

[0062] See also Figure 5 , showing an example diagram of the architecture of a semi-automatic block and automatic station-to-station block system provided by an embodiment of the present invention, in which the axle counting host unit includes a sensor, an axle counting host and an axle counting host (redundant), the block host unit includes a block host I system and a block host II system, the communication unit includes a communication host and a communication host (redundant), the power supply unit includes a power supply module and a power supply module (redundant), and the monitoring unit includes a monitoring host.

[0064] It should be noted that no matter the semi-automatic blocking or the automatic station-to-station blocking function is implemented, there are three scenarios as follows:

[0065] In the first scenario, the two stations communicate through the communication unit of the device itself. This scenario requires a communication unit.

[0066] In the second scenario, the two stations use communication, but there is already inter-station security information transmission equipment on site to achieve communication. This scenario only requires its own communication unit, but needs to be combined with the existing communication unit;

[0067] In the third scenario, the two stations use a real loop line (such as a cable) for transmission. In this scenario, communication units and communication equipment are not required.

[0068] In practical applications, the semi-automatic block and automatic station-to-station block systems provided by the above embodiments of the present invention can be applied to different application scenarios, among which the more common application scenarios are as follows: Figures 6 to 9 As shown; among them, first Figures 6 to 9The English abbreviations are explained as follows: FSBJ is the departure locking relay, JSBJ is the receiving locking relay, BSAJ is the blocking button relay, FUAJ is the recovery button relay, SGAJ is the accident button relay, PJFJ is the ramp departure relay, DLJ is the bell relay, KTXZJ is the opening selection relay, BSDLJ is the blocking bell relay, JGJ is the approach track relay, and WGJ is the non-branch track relay.
