[0002] In the railway transportation system, the inter-station communication system is one of the key technologies to ensure the safe and efficient operation of trains. Traditional single-track railways usually use direct physical connections or simple electrical signals for inter-station communication due to their simple line structure. However, these traditional methods have many limitations, such as slow communication speed, low reliability, high maintenance cost and poor scalability. With the growth of railway transportation demand and the improvement of safety requirements, it is particularly important to develop an efficient and reliable inter-station communication system.

DETAILED DESCRIPTION

[0072] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0073] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0074] The single-line inter-station communication circuit has 6 inter-station cable cores. The present invention proposes a design scheme for realizing the inter-station communication circuit by communication mode, which is used for the inter-station communication design of the single-line inter-station communication circuit.

[0075] 1. For 1 and 2 wire circuits:

[0076] 1, 2 lines are the control lines of line relay XLJ, such as Figure 1 shown.

[0077] The circuit logic of lines 1 and 2 is as follows (taking station A as an example):

[0078]

[0079] Based on the above circuit logic, the station communication combined circuit is designed as follows:

[0080] ①ZDJ repeating circuit

[0081] This station collects the front and rear contacts of ZDJ. If the front contact is closed and the rear contact is disconnected, the ZDJ pickup signal is sent to the neighboring station. If the front contact is disconnected and the rear contact is closed, the ZDJ drop signal is sent to the neighboring station. Otherwise, the ZDJ drops to the neighboring station.

[0082] This station drives ZDJ (neighbor) to rise and fall according to the ZDJ status sent by the neighbor station, such as Figure 2 shown.

[0083] ②XLJ drive circuit

[0084] The driving circuit of XLJ of this station is connected through the front contact of ZDJ (neighbor) and the rear contact of ZDJ of this station, such as Figure 3 As shown, Station B is set up with the same circuit as Station A.

[0085] 2. For 3 and 4 wire circuits:

[0086] 1ZCJ driving circuit.

[0087] The JJ car receiving relay is energized to indicate the car is being received, and the JJ car receiving relay is deenergized to indicate the car is being departed.

[0088] The receiving station supplies power to the departure station, driving the departure station 1ZCJ to be sucked up, allowing the departure station to depart. Figure 4 shown.

[0089] The logic of the 3-wire 1ZCJ circuit is as follows (taking Station A as an example)

[0090]

[0091] Based on the above circuit logic, the station communication combined circuit is designed as follows:

[0092] ①JJ, LXJF, ZDJ-H repeating circuit

[0093] This station collects the front and rear contacts of JJ and LXJF. If the front contact is closed and the rear contact is disconnected, the JJ and LXJF pickup signal is sent to the neighboring station. If the front contact is disconnected and the rear contact is closed, the JJ and LXJF drop signal is sent to the neighboring station. Otherwise, the JJ and LXJF drop signal is sent to the neighboring station.

[0094] This station drives JJ (neighbor) and LXJF (neighbor) to lift and drop according to the JJ and LXJF status sent by the neighboring station.

[0095] Since the 3rd and 4th lines use the rear contact of ZDJ of station B to connect the coil power supply, from the perspective of fault safety, it is necessary to independently repeat the relay of the rear contact of ZDJ to realize the disconnection of the contact after the acquisition failure, drive failure or communication interruption. The logic of ZDJ-H (neighbor) is: when the front contact of ZDJ of the neighboring station is disconnected, the rear contact is closed and sucked up, otherwise it falls down.

[0096] Since the state of LXJF at station B has no effect on the drive of 1ZCJ, the front contact of LXJF will affect the state of 2ZCJ, so the front contact repeater relay of LXJF can ensure fault safety. Figure 5 shown.

[0097] ②1ZCJ, 2ZCJ drive circuit

[0098] The driving circuit of 1ZCJ and 2ZCJ is formed by the contacts of ZDJ (neighbor), JJ (neighbor), LXJF (neighbor) and ZDJ and JJ.

[0099] If JGJ is at the neighboring station, it is necessary to add a repeating circuit of JGJ(neighboring). In the figure below, JGJ is JGJ(neighboring). Figure 6 shown.

[0100] Station B is set up with the same circuit as Station A.

[0101] 3. For 5- and 6-wire circuits:

[0102] Circuits 5 and 6 are the control lines of JQJ and JYGJ of the two stations.

[0103] When the departure station does not have a departure route arranged and the section is idle, JQJ is sucked up;

[0104] When there is no car in the approaching section, JYGJF is sucked up;

[0105] When the distance between stations is less than 800m, the approach section starts from the departure station's exit signal; when the distance between stations is equal to or greater than 800m, the approach section starts from the departure station's exit signal. Figure 7 shown.

[0106] The logic of the 5- and 6-line JYGJ and JQJ circuits is as follows (taking Station A as an example):

[0107]

[0108] Based on the above circuit logic, the station communication combined circuit is designed as follows:

[0109] ①1ZCJ, FSJ, GJJ repeat circuit

[0110] This station collects the front and rear contacts of 1ZCJ, FSJ, and GJJ. When the front contact is closed and the rear contact is disconnected, the 1ZCJ, FSJ, and GJJ pickup signal is sent to the neighboring station. When the front contact is disconnected and the rear contact is closed, the 1ZCJ, FSJ, and GJJ drop signal is sent to the neighboring station. Otherwise, the 1ZCJ, FSJ, and GJJ drop signal is sent to the neighboring station.

[0111] This station drives 1ZCJ (neighbor), FSJ (neighbor), GJJ (neighbor) to lift and drop according to the 1ZCJ, FSJ, GJJ status sent by the neighboring station.

[0112] From the perspective of fault safety, since the front and rear contacts of FSJ at station B will affect the drive of station A, it is necessary to add a repeater relay to the front and rear contacts of FSJ; the rear contact of JJ at station B will connect the drive circuit of station A, so it is necessary to add a repeater relay to the rear contact of JJ, such as Figure 8 shown.

[0113] ②JQJ, JYGJ drive circuit

[0114] The driving circuits of JYGJ and JQJ are formed by the contacts of JJ-H (adjacent), 1ZCJ (adjacent), FSJ (adjacent), FSJ-H (adjacent), GJJ (adjacent) and JJ. Fig. 9 shown.

[0115] Station B is set up with the same circuit as Station A.

[0116] Embodiment 1:

[0118] The line relay control module is responsible for controlling the line relay (XLJ). Its core is to control the lifting and lowering of XLJ through the state change of ZDJ (the state of the station signal equipment); the specific logic is as follows:

[0119] When the ZDJ status of station A is ↓ and the ZDJ status of station B is ↑, if the cable status is normal, the XLJ of station A is sucked up; otherwise, the XLJ falls down;

[0123] The train receiving relay drive module realizes the control of train receiving and departure through the drive circuit of 1ZCJ (train receiving relay); the logic control of 1ZCJ involves multiple conditions, including the status of ZDJ, JJ (train receiving relay), LXJF (train travel direction signal relay) and JGJF (track section idle signal relay);

[0124] For example, when the ZDJ status of station A is ↑, the JGJF status is ↑, the ZDJ status of station B is ↓, the JJ status of station B is ↑, the LXJF status of station B is ↓, and the cable status is normal, station A 1ZCJ is sucked up;

[0125] Expressed as:

[0126]

[0127] Among them, X2 is specifically: Station A ZDJ=↑∩JJ=*∩LXJF=*∩JGJF=↑∩Station B ZDJ=↓∩Station B JJ=↑∩Station B LXJF=↓∩Cable status=normal;

[0128] The departure route control module controls JQJ (request route relay) and JYGJ (advance signal relay) through 5-wire and 6-wire circuits; the status of JQJ and JYGJ depends on multiple conditions such as 1ZCJ, FSJ (departure signal relay), GJJ (track idle signal relay), etc.

[0129] For example, when JJ, 1ZCJ, FSJ, and GJJ at station A are all ↑, JJ at station B is ↓, JGJ is ↑, and 1ZCJ, FSJ, and GJJ at station B are all ↑, and the cable status is normal, JYGJ and JQJ at station A are both sucked up;

[0130] Expressed as:

[0131]

[0132] Among them, X3 is specifically: Station A JJ = ↑ ∩ Station A 1 ZCJ = ↑ ∩ Station A FSJ = ↑ ∩ Station A GJJ = ↑ ∩ Station B JJ = ↓ ∩ JGJ = ↑ ∩ Station B 1 ZCJ = ↑ ∩ Station B FSJ = ↑ ∩

[0133] Station B GJJ = ↑∩Cable status = normal;

[0143] Drive execution unit: activates or deactivates 1ZCJ according to the output of the logic judgment unit; this unit is designed with safety measures to prevent 1ZCJ from being driven incorrectly in a fault state.

[0144] Wherein, the departure route control module includes:

[0145] Route setting unit: responsible for configuring and planning the train departure route; dynamically adjust the route setting according to the signal status of FSJ (departure signal relay), GJJ (track idle signal relay), etc. to adapt to different departure requirements;
