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, 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 platform gate control circuit, method and apparatus of the present invention are described below with reference to fig. 1 to 6.
As shown in fig. 1 to 3, the present invention provides a station gate control circuit, which includes: 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 switching states of the working output end and the standby output end are synchronous, and the control relay assembly is composed of an European standard safety relay.
It will be appreciated that the control relay assembly may be comprised of one or more euro standard safety relays which are less heavy and less bulky than gravity type relays.
The traditional gravity type relay is a fault guiding safety relay, when the relay breaks down, for example, after the relay loses magnetism or the contacts are welded, the relay contacts can be forcibly pulled open through armature gravity, the rear contacts in all the contacts are switched on, meanwhile, the relay circuit switches on the rear contacts to be set to be in a safety side state, and the fault caused by the relay can be processed according to the safety side after the external interface or the interlocking device 10 outputs and collects the rear contact state.
The European standard safety relay is a reaction type safety relay, has a forced guide contact structure, has no defined safety side, and the European standard safety relay selected by the current scattered circuit accords with the forced guide (mechanical connection) attribute: the design of the relay ensures that if any normally closed contact is closed, forced guidance ensures that all normally open contacts cannot be closed, and if any normally open contact is closed, forced guidance ensures that the normally closed contact cannot be closed, and the function needs to be effective in the whole life cycle of the relay even under certain reasonably predictable fault states. The function of the positive guidance should not be affected by a reasonably foreseen breakage or wear of the relay components. In the specified service life, the electric shock gap of the relay on electric shock is larger than 0.5mm for single contact electric shock, and the double contacts are larger than 0.3mm for double contact electric shock. 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 adhered, all normally open contacts can not be closed when the relay is electrified.
Therefore, the current european standard safety relay can guarantee the safety of the following two states: firstly, any normally open contact is welded, after the relay is powered off, all normally closed contacts cannot be normally closed (the normal clearance is larger than 1mm, and the clearance is larger than 0.5mm) due to the action of a forced guide rod, and the system can judge the relay fault by acquiring the open state of the normally closed contacts; secondly, the welding phenomenon occurs at any normally closed contact, after the relay is electrified, all normally open contacts can not be normally closed (the normal clearance is larger than 1mm, the clearance is larger than 0.5mm at the moment) due to the action of the forced guide rod, and the system can judge the relay fault by acquiring the open state of the normally open contacts at the moment.
The control relay assembly is provided with an input end, a working output end and a standby output end, wherein the working output end is used for responding according to the driving signal of the input end and presenting corresponding switch state change, the control relay assembly is provided with the forced guide attribute of the European standard safety relay, and the standby output end is synchronous with the switch state of the working output end, namely, the working output end and the standby output end can keep the same switch state under the normal working state of the control relay assembly.
