On the premise of flexible and efficient operation of a pneumatic train of a communication-based train automatic control system (Communication Based Train Control, CBTC) system, the existing state analysis and adjustment method of the equipment beside the pneumatic train can not meet the requirements of efficiency and safety.

Further, in an embodiment, in a case where the protection function of the interlock control is to prevent the pneumatic train from being hostile, the interlock logic constraint of the trackside device of the pneumatic train system may specifically include:

and under the condition that another train exists in the route where the pneumatic train is located, at most one centrifugal fan works in the route where the pneumatic train is located, and the centrifugal fan is used for providing traction for the pneumatic train.
Further, in one embodiment, the determining the occupation direction of the first section includes:
and determining the occupation direction of the first section according to the occupation direction of a second section and the running direction of the pneumatic train, wherein the second section is a section adjacent to the first section.
Alternatively, the first section may be a section where the pneumatic train is located, the locking direction of the first section may specifically include from up to down or from down to up, and the occupation direction of the first section may specifically include from up to down or from down to up. The occupation direction of the first section can be determined according to the occupation direction of a second section adjacent to the first section and the running direction of the pneumatic train.
For example, when the occupation direction of the second section is from up to down, and the running direction of the pneumatic train is from up to down, the occupation direction of the first section is from up to down; when the occupation direction of the second section is from the descending direction to the ascending direction and the running direction of the pneumatic train is from the descending direction to the ascending direction, the occupation direction of the first section is from the descending direction to the ascending direction;

when another train exists in the route of the pneumatic train, at most one centrifugal fan works in the route of the pneumatic train, and the centrifugal fan is used for providing traction for the pneumatic train.
The interlocking logic constraints of the trackside equipment of the pneumatic train system are determined by:

In the same way, two or more centrifugal fans are forbidden to work simultaneously (in the case that another train exists in the way of the pneumatic train, at most one centrifugal fan works in the way of the pneumatic train), in the extreme case, if the pneumatic train and the other train oppositely enter the same way, only one centrifugal fan works to ensure that only one train in the same way is towed at the same moment, and due to inherent air pressure between the two trains, the two trains can be prevented from collision/reduction.

and under the condition that the turnout where the pneumatic train is located is a single-acting turnout and the single-acting turnout is locked in a straight direction, closing and locking all valve body equipment after the turnout of a third section where the single-acting turnout is located, and locking a baffle plate in a hollow beam in the third section to be in a straight-direction opening position until the third section is idle.
Optionally, for the case where the protection of the interlock control is to prevent side-impact of the pneumatic train, the interlock logic constraints of the trackside equipment of the pneumatic train system may specifically include:
when the switch of the pneumatic train is a single-acting switch and the single-acting switch is locked in a straight direction, all valve body devices (such as an atmosphere valve VA and an isolation valve VIT) are reversed after the switch of the section (namely a third section) of the single-acting switch is closed and locked, and a baffle in a hollow beam in the third section is locked in a straight-direction opening position until the third section is idle.
The interlocking logic constraints of the trackside equipment of the pneumatic train system are determined by:
for preventing the side impact of the pneumatic train, the switch system of the pneumatic train is similar to the switch system of the traditional rail transit, is guided by wheel tracks, and can control the trend of the train through the trend of the steel rails. However, due to its air-driven nature, the switch system has another guide means inside the hollow beam, namely a barrier closing the passageway of the inverted hollow beam behind the switch or a barrier closing the fixed hollow beam behind the switch.
When the turnout of the pneumatic train is a single-acting turnout, after the single-acting turnout is locked in a straight direction, all valve body devices (such as an atmospheric valve VA and an isolation valve VIT) are locked in a closed and locking state after the third section turnout of the single-acting turnout, and meanwhile, a baffle in the hollow beam is locked in a straight-direction opening position until the third section is idle.
Further, in an embodiment, in a case that the protection function of the interlocking control is to prevent the side impact of the pneumatic train, the interlocking logic constraint of the trackside device of the pneumatic train system may further specifically include:
when the turnout where the pneumatic train is located is a double-acting turnout and a first turnout in the double-acting turnout is locked in a straight direction, all valve body devices are turned back after a fourth section turnout where the first turnout is located is closed and locked, and a baffle in a hollow beam in the fourth section is locked to be in a straight-direction opening position;

and under the condition that a fifth section where the second turnout in the double-acting turnout is located is unoccupied, locking all valve body equipment in the fifth section to be in a locking state of being closed in a straight direction and closed in a lateral direction, and locking a baffle plate in a hollow beam in the fifth section to be in a straight-direction opening position.
Optionally, for the case where the protection of the interlock control is to prevent side-impact of the pneumatic train, the interlock logic constraint of the trackside equipment of the pneumatic train system may further specifically include:
when the switch of the pneumatic train is a double-acting switch and a first switch in the double-acting switch is locked in a straight direction, all valve body devices which are reversed after the switch of the section where the first switch is located (namely a fourth section) are closed and locked, and a baffle plate in a hollow beam in the fourth section is locked to be in a straight-direction opening position;
when the section (namely a fifth section) where the second turnout in the double-acting turnout is located is occupied, locking all valve body equipment in the fifth section into locking states of opening in a straight direction and closing in a lateral direction, and locking a baffle plate in a hollow beam in the fifth section into a straight opening position;
when the fifth section is unoccupied, all valve body devices in the fifth section are locked in a straight-closed and laterally-closed locking state, and the shutters in the hollow beams in the fifth section are locked in a straight-open position.
For example, fig. 4 is a schematic diagram of a state of a track side device when a double-acting switch is locked in a straight direction, as shown in fig. 4, a first switch is locked in a straight direction, an isolation valve VIT and an atmospheric valve VA opposite to the first switch at the back of a switch section 1 are locked in a closed and locked state, a baffle plate in a hollow beam in the switch section 1 is at a straight open position, at this time, a switch section 2 where a second switch is located is not occupied, all valve body devices in the locked switch section 2 are locked in a straight closed and laterally closed locked state, and the baffle plate in the hollow beam in the locked switch section 2 is locked in a straight open position. The state of each trackside equipment in the pneumatic train system is shown in fig. 5 for the case where the double-acting switch is locked sideways.
The invention adopts traditional interlocking safety function analysis to process novel interlocking objects, namely, the main functions of traditional rail transit interlocking are transferred to a pneumatic train system through logic constraint, and the designed interlocking logic constraint breaks through the barriers of unified control and unified scheduling of all-line resources, so that the resource utilization rate is higher, and the safety and reliability are better.
