Fig. 3 is a flowchart of a control method of an elevator lighting system according to an embodiment of the present application, where the flowchart shown in fig. 3 includes:

step S101: starting.

Specifically, when the elevator starts to operate, the control method of the elevator lighting system in the present application starts to be implemented by means of the electrical schematic diagram as shown in fig. 4. Fig. 4 is an electrical schematic diagram of an elevator illumination system provided in an embodiment of the present application, as shown in fig. 4, an illumination power supply 130 of an elevator is connected to both sides of a coil of a relay K1 and terminals 11 and 12 of a normally open contact 1, an emergency power supply 120 of the elevator is connected to terminals 21 and 22 of a normally closed contact 2 of the coil of the relay K1, and a power line of an illumination lamp 110 is connected to terminals of movable contacts 13 and 14 of the relay K1; the photosensitive element 142 is arranged at a position where the illumination lamp 110 can receive illumination but other illumination can not be received, the sensitivity of the photosensitive switch 141 is adjusted, the DC24V anode of the IO port of the elevator control module is connected with the COM terminal of the photosensitive switch 141, the NO terminal of the photosensitive switch 141 is connected with the feedback signal transmission module 170, and the feedback signal transmission module 170 is connected with the elevator control module.

Step S102: whether the relay is operating.

Specifically, it is determined whether the moving contact in the relay is operated, when the moving contact in the relay is operated, that is, the power supplies at both sides of the relay coil are normally powered, the operation state of the elevator is a normal state, step S103 is executed, when the moving contact in the relay is reset, the operation state of the elevator is an emergency state when the power supplies at both sides of the relay coil are lost, and step S104 is executed, thereby completing the switching of the power supply of the illumination lamp 110 through the relay K1.

Step S103: the normally open contact of the relay K1 is closed, and the normally closed contact is opened.

Specifically, when the power supplies at the two sides of the coil of the relay K1 are normal, the movable contact in the relay acts, that is, the movable contact in the relay is closed with the normally open contact 1, and the movable contact is disconnected with the normally closed contact 2, so that the illumination lamp 110 is powered by the illumination power supply 130.

Step S104: the normally open contact of the relay K1 is opened, and the normally closed contact is closed.

Specifically, when the power supplies at two sides of the coil of the relay K1 disappear, the movable contact in the relay is reset, namely the movable contact in the relay is disconnected with the normally open contact 1, and the movable contact is closed with the normally closed contact 2, so that the illuminating lamp 110 is powered by the emergency power supply 120.

At the moment when the movable contact of the relay is closed with the normally open contact 1 and is disconnected with the normally closed contact 2, or at the moment when the movable contact of the relay is opened with the normally open contact 1 and is closed with the normally closed contact 2, the capacitor 200 supplies power to the illuminating lamp 110.

Step S105: whether the normally open contact of the photosensitive switch is closed.

Further, when the elevator is in a normal state and an emergency state, the illumination lamp 110 is powered by a power supply, under the normal conditions of a circuit and equipment, the illumination lamp 110 can be lightened, further, the illumination of the illumination lamp 110 is obtained through the photosensitive element 142 and is transmitted to the photosensitive switch 141, further, the movable contact of the photosensitive switch 141 is driven to act with a normally open contact or act with a normally closed contact according to the illumination, and therefore an abnormal illumination detection signal is output.

Specifically, when the movable contact and the normally open contact of the photosensitive switch 141 are closed, it indicates that the illuminance of the illumination lamp 110 meets the requirement, that is, the illuminance of the illumination lamp 110 is greater than or equal to the preset illuminance threshold, step S109 is executed; when the movable contact of the photosensitive switch 141 is disconnected from the normally open contact, it indicates that the illuminance of the illumination lamp 110 does not meet the requirement, that is, the illuminance of the illumination lamp 110 is less than the preset illuminance threshold, so as to generate an illuminance abnormality feedback signal, and step S106 is performed.

As shown in table fig. 5, fig. 5 is a state diagram of a relay provided in the embodiment of the present application, and as shown in fig. 5, when a lighting power supply supplies power normally, the power supplies at two sides of a relay coil supply power normally, and a moving contact of the relay is induced to act by the energizing of the coil so as to be closed with a normally open contact 1 and be disconnected with a normally closed contact 2; when the illumination power supply is powered off, the power supplies at the two sides of the relay coil disappear, the movable contact of the relay is reset, the movable contact of the relay is disconnected with the normally open contact 1, and the movable contact of the relay is closed with the normally closed contact 2.

Step S106: the feedback signal module transmits an abnormal illuminance feedback signal.

Specifically, when the illuminance of the illumination lamp 110 is smaller than the preset illuminance threshold value, an illuminance feedback signal with abnormal illuminance of the illumination lamp 110 is obtained, and then the feedback signal transmission module transmits the abnormal illuminance feedback signal to the elevator control module, and further, the elevator control module can output a control signal for reporting a fault to other functional modules of the elevator to perform preliminary fault processing on the elevator, for example, output the control signal for reporting the fault to the motor to control the elevator to stop running.

Step S107: the elevator control module generates a fault signal and sends it to the gateway.

Further, the elevator control module may also generate a fault signal according to the abnormal illuminance feedback signal and send the fault signal to the gateway.

Step S108: the gateway transmits the fault signal to the remote monitoring platform.

Further, the gateway transmits the fault signal to the remote monitoring platform, so that a manager of the remote monitoring platform maintains the elevator, and the fault of the elevator is solved timely.

Step S109: and (5) ending.

Finally, the flow is ended.
