Detailed Description
The present invention will be described in further detail by way of examples with reference to the accompanying drawings, which are illustrative of the present invention and are not intended to limit the present invention.
Basically, the design of an elevator has the energy-saving function of an illuminating lamp, when no one uses the elevator, the illuminating lamp can automatically cut off the power supply and turn off, and when the elevator is used by a person, the power supply of the illuminating lamp is automatically switched on to light the illuminating lamp. By utilizing the energy-saving function, the illuminating lamp is turned on when the elevator is used, the ultraviolet disinfection lamp is turned off, and the illuminating lamp is turned off when no person uses the elevator, and the ultraviolet disinfection lamp is turned on for disinfection.
Generally elevators can enable an elevator energy saving mode by accessing an elevator programming server. Taking a fast elevator in the south of the Yangtze river as an example: the method for setting the energy-saving mode of the elevator comprises the following steps: an elevator programming server is plugged in an elevator control main board, the input 132 enters an energy-saving function program for programming, the input address 051 starts an energy-saving mode and confirms, and the input 1311 enters an LR-T program for adjusting the time of starting an ultraviolet lamp when an elevator is not used, so that the energy-saving mode is started.
The method for installing the ultraviolet lamp on the elevator is shown as the following embodiment:
example one
The method for refitting the elevator car with the intermediate relay originally exists, and the intermediate relay of a 24V coil power supply is generally installed on the elevator car roof.
Referring to fig. 1, during modification, the ultraviolet disinfection lamp and the illuminating lamp are connected in parallel through two branches, and the two branches are respectively connected to the normally open contact and the normally closed contact of the intermediate relay.
When someone uses the elevator, any key switch of the elevator is pressed, the elevator control main board receives an elevator use signal and immediately outputs 24V voltage to the intermediate relay coil, the normally open contact of the intermediate relay is closed (the 9 feet and the 5 feet are electrified), the lighting lamp circuit control line (live wire) is connected, the lighting lamp is turned on by the lighting lamp function to realize the lighting lamp, and meanwhile the normally closed contact of the intermediate relay is opened (the 9 feet and the 1 feet are opened) (remarks: the 9 feet and the 5 feet are in an interlocking relationship, the 9 feet and the 5 feet are closed, the 9 feet and the 1 feet are in an open state, the 9 feet and the 5 feet are open, and the 9 feet and the 1 feet are in a closed state).
Because the power supply control line of the added ultraviolet disinfection lamp is connected in series with the normally closed contact (9 feet and 1 foot) of the intermediate relay, when the elevator is used, the coil of the intermediate relay is electrified, the control line of the lighting lamp string at 9 feet and 5 feet is closed and switched on, and the lighting lamp is started. 60 seconds (the time can be set, such as 30 seconds or 60 seconds of stopping) after no one uses the elevator, the line of the lighting lamp connected in series with the 9 feet and the 5 feet is disconnected, the 9 feet and the 1 feet are reset and connected, the ultraviolet disinfection lamp connected in series with the 9 feet and the 1 feet is connected, and the ultraviolet disinfection lamp starts disinfection. In order to prevent the relay contactor from being out of order, the ultraviolet disinfection lamp cannot be automatically turned off and harms human bodies, therefore, an emergency switch is arranged in the car in a series mode in the control circuit and used as an emergency stop ultraviolet disinfection lamp, and the use safety of the ultraviolet disinfection lamp is guaranteed. The coil operating voltage of the intermediate relay is 24V.
Circuit symbols and component designations in fig. 1 illustrate: KA is an intermediate relay; l is a ballast; s is a starter; (9) is a relay common point; (5) is a normally open contact; (1) is a normally closed contact; l1 is a lighting power supply phase line; n is a power supply zero line and is public; k is an emergency switch.
Example two
When the elevator car is not provided with an intermediate relay (such as a Hitachi and Guangdi elevator), the power supply of the lighting lamp circuit is directly controlled by the module of the elevator car, but the voltage of the lighting lamp circuit is 220V power supply. The ultraviolet disinfection lamp and the illuminating lamp can be connected into two branches, and the two branches are respectively connected into two power supplies. The power supply of one of the ultraviolet disinfection lamps is connected to the elevator control main board, the electrifying control module and the ultraviolet disinfection lamp are connected in series in the same branch, the power supply of the other of the ultraviolet disinfection lamps is controlled by the elevator control main board, the ultraviolet disinfection lamp and the intermediate relay are electrified simultaneously, the branch where the ultraviolet disinfection lamp is located is connected with the relay common point and the normally closed contact of the intermediate relay, after the intermediate relay is powered off, the relay common point and the normally closed contact are connected, and the branch where the ultraviolet disinfection lamp is located is electrified.
Referring to fig. 2, in particular, the improvement is as follows: an intermediate relay with 220V coil voltage is added on the original lighting lamp circuit, a coil KA power supply is directly connected in parallel in the lighting lamp circuit, an ultraviolet disinfection lamp is additionally provided with a power supply (such as a car exhaust fan and a camera), a power supply control line is connected in series with a normally closed contact (9 feet and 1 foot) of the intermediate relay, when an elevator is used, the lighting lamp is electrified for lighting, an intermediate breaker coil is electrified, the control line of the ultraviolet disinfection lamp in series with the 9 feet and 1 foot is disconnected and closed, the situation that an elevator user can not irradiate ultraviolet rays at the moment is ensured, the safety is ensured, when the elevator is not used by the user, an elevator control main board controls the power supply of the lighting lamp to be disconnected, the intermediate relay coil is powered off, the ultraviolet disinfection lamp is connected with the control line (live wire) of the 9 feet and 1 foot in a reset way, the ultraviolet disinfection lamp is started for disinfection, in order to prevent the intermediate relay from being out of fault, and the ultraviolet disinfection lamp can not be automatically closed, the human body is hurt, therefore, an emergency switch is arranged in the car in series in the control circuit to be used as an emergency stop ultraviolet disinfection lamp, and the use safety of the ultraviolet disinfection lamp is ensured.
Circuit symbols and component designations in fig. 2 illustrate: KA is an intermediate relay; l is a ballast; s is a starter; (9) is a relay common point; (1) is a normally closed contact; l1 is the phase line of the original lighting power supply; l2 is newly added ultraviolet power phase line; n is a zero line and is public; k is an emergency switch.
The above description in this specification is merely illustrative of the present invention. Various modifications, additions and substitutions may be made by those skilled in the art without departing from the scope of the invention as defined in the accompanying claims.
