Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes the platform door control circuit, method and apparatus of the present invention with reference to fig. 1 to 6.
As shown in fig. 1 to 3, the present invention provides a station door control circuit including: a control relay assembly (not shown), a controlled relay assembly (not shown), an interlock device 10 and a platform door device 20.
The control relay assembly is provided with an input end, a working output end and a standby output end, wherein the working output end and the standby output end are synchronous in switching state, and the control relay assembly is composed of European standard safety relays.
It will be appreciated that the control relay assembly may be comprised of one or more euro-standard safety relays, which are of lower weight and smaller volume than gravity-type relays.
The conventional gravity type relay is a fault-oriented safety relay, after the relay has faults, such as loss of magnetism or contact fusion, the relay contacts can be forcibly pulled apart through the gravity of an armature, and the rear contacts in all the contacts are connected, meanwhile, the relay circuit sets the rear contacts to be connected to a safety side state, and the external interface or the interlocking device 10 can treat the faults caused by the relay according to the safety side after collecting the rear contact state.
The European standard safety relay is a reactive safety relay and is provided with a forced guiding contact structure, a non-defined safety side and the European standard safety relay selected by the current scattered circuits accords with the forced guiding (mechanical connection) attribute: the design of the relay ensures that if any normally-closed contact is closed, the forced guiding ensures that all normally-open contacts cannot be closed, and if any normally-open contact is closed, the forced guiding ensures that the normally-closed contacts cannot be closed, and the function needs to be effective in the whole life cycle of the relay even in certain reasonably predictable fault states. The reasonably foreseen breakage or wear of the relay components should not affect the forced guiding function. The single contact electric shock of the electric shock gap of the relay switch electric shock should be larger than 0.5mm and the double contact should be larger than 0.3mm within the specified service life. The forced guiding means that if any normally open contact is adhered, all normally closed contacts cannot be closed when the relay is powered off; if any normally-closed contact is stuck, all normally-open contacts cannot be closed when the relay is electrified.
Therefore, the current European standard safety relay can ensure the safety of the following two states: firstly, welding occurs on any normally open contact, after the relay is powered off, all normally closed contacts cannot be normally closed (a normal clearance is more than 1mm, and the clearance is more than 0.5 mm) due to the action of a forced guide rod, and at the moment, the system can judge the relay fault by collecting the opening state of the normally closed contacts; secondly, welding occurs on any normally closed contact, after the relay is electrified, all normally open contacts cannot be normally closed (the normal clearance is more than 1mm, and the clearance is more than 0.5 mm) due to the action of the forced guide rod, and at the moment, the system can judge the relay fault by collecting the open state of the normally open contacts.
The control relay assembly has an input end, and a working output end and a standby output end with synchronous switching states, the input end is used for inputting a driving signal, the working output end is used for responding according to the driving signal of the input end, corresponding switching state changes are presented, the control relay assembly has the forced guiding attribute of the European standard safety relay, and the standby output end is synchronous with the switching states of the working output end, that is, the control relay assembly can keep the same switching states in the normal working state.
The controlled relay assembly has an input and an operational output.
It will be appreciated that the controlled relay assembly may also include one or more euro-standard safety relays, and that the controlled relay assembly may have an input and an operational output, the operational output being responsive to the switching state of the input to present a particular switching state to control the on-off of the electrical signal in the circuit in which it is located.
As shown in fig. 2, the drive end of the interlock device 10 is connected to the input of the control relay assembly as a drive loop 40.
It is understood that the interlock device 10 refers to a device that controls the switches, approaches, and signals of the station and implements an interlocking relationship therebetween. The interlock device 10 may be controlled either in a decentralized manner or in a centralized manner. The interlock device 10 has two main types, namely relay interlock and computer interlock. The interlock device 10 has a drive end, the drive end of the interlock device 10 being able to generate a drive signal, the drive end of the interlock device 10 being electrically connected to an input of the control relay assembly, forming a drive circuit 40.
When the drive end of the interlock device 10 generates a drive signal, the input end of the control relay assembly is able to receive the drive signal and respond to the drive signal, thereby controlling the switching states of the working output and the standby output based on the electromagnetic principle.
As shown in fig. 1, the working output of the control relay assembly is connected to the input of the controlled relay assembly to form a control loop 30.
It may be understood that the working output end of the control relay assembly is electrically connected to the input end of the controlled relay assembly, for example, may be in series connection, the working output end of the control relay assembly and the input end of the controlled relay assembly together form the control loop 30, and the working output end of the control relay assembly may adjust the on-off state of the control loop 30, thereby adjusting the on-off state of the input end of the controlled relay assembly.
The operational output of the controlled relay assembly is electrically connected to the platform door arrangement 20 for controlling the opening and closing state of the platform door.
It will be appreciated that the on-off state of the input of the controlled relay assembly can affect the on-off state of the operational output of the controlled relay assembly, which is electrically connected to the platform door device 20, such as an electronic component in the platform door device 20 that controls the opening and closing of the platform door, and the output of the controlled relay assembly can be connected in series with the electronic component, such that the operational output of the controlled relay assembly can control the on-off state of the platform door.
As shown in fig. 3, the collection end of the interlock device 10 is connected to the standby output end of the control relay assembly in a collection circuit 50.
