Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The control circuit of the three-throw switch of the present invention will be described with reference to fig. 1 to 3.
The control circuit of the three-throw turnout is applied to urban rail transit, such as subways.
It should be noted that the three-throw turnout of the present application can be equivalent to two single-acting turnouts, namely a first turnout and a second turnout.
The opening direction of each single-acting switch is controlled by a set of switching devices, which are specifically determined by controlling the position of a set of switch rails. Each group of switch rails comprises 1 short switch rail and 1 long switch rail, and the positions of the turnouts can be judged through the repulsion state and the close contact state of the switch rails.
Each set of conversion equipment comprises a switch machine, two close-contact inspectors and corresponding mounting devices. The switch machine is used for switching the position of the turnout, changing the opening direction of the turnout and locking the switch blade of the turnout; the close contact detector is used for detecting the close contact state and the repulsion state of the switch rail.
For example, the switches may be three-phase ac switches of a five-wire control circuit that is standard in the original railroad department.
As shown in fig. 1, the control circuit for three-way switch includes: the starting circuit and the first relay combined circuit.
The starting circuit is used for controlling the switch machine to execute positioning or reverse operation.
The starting circuit is connected with the first relay combination circuit and is controlled by the first relay combination circuit.
The first relay combination circuit comprises a first branch, one end of the first branch is connected with a control negative power supply KF, and the other end of the first branch is connected with a control positive power supply KZ through other components.
In fig. 1, FCJ is the flip action relay of the first switch, and DBJ is the positioning indication relay of the second switch.
The positioning action relay of the second turnout and the reverse action relay of the first turnout are jointly used for controlling the position of the switch rail of the first turnout. When the first turnout is in a locating state towards the locating operation, the locating action relay of the first turnout is sucked up, and the reverse action relay of the first turnout falls down; or when the first turnout is operated to the reverse position, the reverse position action relay of the first turnout is sucked up, and the positioning action relay of the first turnout falls down.
It should be noted that the reverse action relay of the first switch is normally driven only when the positioning of the second switch indicates that the relay is in the suck-up state, and the first branch circuit is turned on only when the reverse action relay of the first switch is in the suck-up state.
Under the condition that the first branch is conducted, the starting circuit controls a switch motor of the first turnout to perform a reverse operation so as to enable the first turnout to be in a reverse state.
With continued reference to fig. 1, in some embodiments, the first relay combination circuit further includes a second branch, one end of the second branch is connected to the negative control power supply, and the other end of the second branch is connected to the positive control power supply via another component.
And the excitation coil of the positioning action relay of the first turnout is connected in series with the second branch.
And when the positioning action relay of the first turnout is in the suck-up state, the second branch is conducted.
Under the condition that the second branch circuit is conducted, the starting circuit controls a switch motor of the first turnout to perform positioning operation so as to enable the first turnout to be in a positioning state.
In fig. 1, DCJ is a positioning action relay of the first switch.
It should be noted that, in the actual execution process, the reverse operation relay of the first switch and the positioning operation relay of the first switch are not in the suck-up state at the same time. Namely when the reverse action relay of the first turnout is in a suction state, the positioning action relay of the first turnout is kept in a falling state; when the positioning action relay of the first turnout is in a sucking-up state, the reverse action relay of the first turnout keeps a falling state.
The connection of the first relay combination circuit in the control circuit is shown in fig. 2.
The control circuit includes a positioning operation relay for a plurality of first switches and a reverse operation relay for a plurality of first switches.
In some embodiments, the control circuit further comprises: and a second relay combination circuit.
In this embodiment, the start circuit is also connected to, and controlled by, the second relay combination circuit.
The second relay combination circuit comprises a third branch circuit, one end of the third branch circuit is connected with the control negative power supply, and the other end of the third branch circuit is connected with the control positive power supply through other components.
The excitation coil of the reverse action relay of the second switch and the positioning of the first switch show that the contact of the relay is connected in series with the third branch.
And the positioning action relay of the second turnout and the reverse action relay of the second turnout are jointly used for controlling the position of the switch rail of the second turnout. When the second turnout is in a locating state towards the locating operation, the locating action relay of the second turnout is sucked up, and the reverse action relay of the second turnout falls down; or when the second turnout is operated to the reverse position, the reverse position action relay of the second turnout is sucked up, and the positioning action relay of the second turnout falls down.
It should be noted that the reverse action relay of the second switch is normally driven only when the positioning of the first switch indicates that the relay is in the suck-up state, and the third branch is turned on when the reverse action relay of the second switch is in the suck-up state.
After the third branch is conducted, the starting circuit controls a switch motor of the second turnout to execute a reverse operation, so that the second turnout is in a reverse state.
In some embodiments, the second relay combination circuit further comprises a fourth branch.
In this embodiment, one end of the fourth branch is connected to the negative control power supply, and the other end of the fourth branch is connected to the positive control power supply through another component.
And the excitation coil of the positioning action relay of the second turnout is connected in series with the fourth branch.
And the fourth branch circuit is conducted when the positioning action relay of the second turnout is in a suction state, and the starting circuit controls the switch motor of the second turnout to execute positioning operation under the action of the positioning action relay of the second turnout so as to enable the second turnout to be in a positioning state.
Also, it will be appreciated that during actual operation, the reverse action relay of the second switch and the positioning action relay of the second switch will not be in the pick-up state at the same time. Namely when the reverse action relay of the second turnout is in a sucking-up state, the positioning action relay of the second turnout keeps a falling state; when the positioning action relay of the second turnout is in a sucking-up state, the reverse action relay of the second turnout keeps a falling state.
The connection mode of the second relay combination circuit in the control circuit is similar to that of the first relay combination circuit, and is not described herein.
An embodiment of the present invention will be described below by taking a set of three-throw switches 2504 as an example.
The three-throw turnout 2504 can be equivalent to a first turnout A and a second turnout B of two single-action turnouts, wherein the first turnout A corresponds to a switch machine A for controlling the movement of a switch point, the second turnout B corresponds to a switch machine B for controlling the movement of the switch point, the machine A is arranged in front, the machine B is arranged behind, the front of the switch where the machine B is arranged is separated from the rear of the switch where the machine A is arranged by a target distance, and an equivalent circuit of the three-throw turnout 2504 is shown in fig. 4.
The target distance may be user-defined, such as set to 2 cm.
By taking the direction facing the switch point as a reference, the three-throw turnout can open three direction positions of a straight direction, a left direction and a right direction, and the three-throw turnout is specifically represented as follows:
when the first turnout A is in a positioning state and the second turnout B is in a reverse state (namely the machine A is in the positioning state and the machine B is in the reverse state), the three-throw turnout is opened at a left position and is represented by 2504A (B);
when the first turnout A is in a positioning state and the second turnout B is in a positioning state (namely the machine A is in a positioning state and the machine B is in a positioning state), the three-throw turnout is opened to a straight position and is represented by 2504 AB;
when the first switch a is in the reverse position and the second switch B is in the positioning state (i.e., the machine a is in the reverse position and the machine B is in the positioning state), the three-way switch is opened to the right position, which is denoted by 2504(a) B.
In the research and development process, the inventor finds that in the related art, for the control of the three-throw turnout, a software control method is often adopted, for example, a program instruction is used for controlling an a machine and a B machine to execute operation so as to control the positioning or the reverse state of a first turnout a and a second turnout B, thereby controlling the opening direction of the three-throw turnout.
In the related art, the situation that a program instruction simultaneously controls a machine A and a machine B to execute reverse operation easily occurs, and under the situation, a first turnout A and a second turnout B are simultaneously in a reverse state, so that the opening direction of a three-throw turnout is disordered, the structural damage of the turnout is caused, the driving safety is seriously influenced, and the loss of life and property is caused.
In the invention, a control circuit is added on the basis of the control of the program instruction. Through in the first branch road of the first switch A of control execution reversal operation, the excitation coil of the reversal action relay of first switch A and the contact series connection of second switch B express the relay insert first branch road, make only under the condition that the location at second switch B expressed the relay and sucked, first switch A can be to the reversal operation, this first branch road just can switch on, thereby guarantee only when second switch B is in the positioned state, first switch A just can execute the reversal operation, the condition that first switch also executed the reversal operation when the second switch is in the reversal state has been avoided.
In the same way, in the third branch circuit for controlling the second turnout B to execute the reversal operation, the excitation coil of the reversal action relay of the second turnout B and the contact of the relay are connected in series to the third branch circuit, so that only when the positioning of the first turnout A shows that the relay is sucked up, the second turnout B can be operated to the reversal operation, the third branch circuit can be switched on, thereby ensuring that only when the first turnout A is in the positioning state, the second turnout B can execute the reversal operation, and avoiding the situation that the second turnout B also executes the reversal operation when the first turnout A is in the reversal state.
Through the control circuit of the three-throw turnout, even if the control instruction is disordered (for example, the control instruction controls the machine A and the machine B to execute the reversal operation at the same time), the first branch and the third branch in the control circuit can not be conducted, so that the starting circuit for controlling the point machine to execute the switching operation is in the power-off state, the control instruction can not be executed, the condition that the first turnout A and the second turnout B are in the reversal state at the same time is avoided, the control logic of the control circuit of the three-throw turnout is obviously improved, the control disorder is avoided, and the operation safety of urban rail transit is improved.
Continuing with the three switch 2504(2503) as an example, the logic instructions that can be implemented by the control circuit of the three switch of the present invention will be described, and the logic relationship between the first switch a and the second switch B is shown in table 1.
TABLE 1
Where the loss table is used to characterize a switch as being abnormal.
The square root represents that the turnout operation command can be executed; x represents that the switch operation cannot be performed and the guard switch needs to be operated to the location first and return to the location representation to be operable.
For example, when a first switch a of the three-throw switches is in the positioning state, the second switch B may perform a positioning-to-unset or a unset-to-position operation based on a control circuit of the three-throw switches; and when the first turnout A is in the reverse position state, the second turnout B can only execute the operation of reversing to positioning based on the control circuit of the three-throw turnout, thereby avoiding the situation that the first turnout A and the second turnout B are in the reverse position state at the same time.
According to the control circuit of the three-throw turnout provided by the embodiment of the invention, the positioning indication relay of the second turnout is connected in series in the branch for controlling the first turnout to execute the reversal operation, so that the branch can be switched on only when the second turnout is in the positioning state, and the first turnout can execute the reversal operation, thereby ensuring that the second turnout is in the positioning state when the first turnout is in the reversal state, avoiding the situation that the second turnout and the first turnout are in the reversal state at the same time.
