The operation of the elevator system based on power carrier and IP network clustering according to an embodiment of the present invention is described below.
For example, in the inter-call process, when the passenger presses a floor button in the car, the inter-call board 252 sends an inter-call data signal having a CAN bus communication protocol format to the second protocol conversion module 32, and the second protocol conversion module 32 converts the inter-call data signal into an IP data packet and sends the IP data packet to the car network switch 41. The IP data packet includes a local MAC address and a local IP address of the second protocol conversion module 32, a MAC address and an IP address (i.e., a destination MAC address and a destination IP address) of the third protocol conversion module 33, call-in data information, a hardware address of the elevator main control module 27, and the like. The car network switch 41 transmits the IP packet to the car power carrier communication module 12, and the car power carrier communication module 12 modulates the IP packet into a power carrier signal and transmits the power carrier signal on the first harness 81. The outbound power carrier communication module 11, the pit power carrier communication module 13, and the first machine room power carrier communication module 14 detect the IP data packet on the first harness 81, determine whether the IP data packet is addressed to the first machine room power carrier communication module, and if not, do not perform further processing. Since the IP data packet contains the MAC address and the IP address of the third protocol conversion module 33, the first machine room power carrier communication module 14 receives the power carrier signal on the first wire harness 81, demodulates the power carrier signal into the IP data packet, and then packages the demodulated IP data into the machine room network switch 42. The machine room network switch 42 sends the IP packet to the third protocol conversion module 33 according to the destination MAC address and the destination IP address. The third protocol conversion module 33 converts the IP data packet into data conforming to the CAN bus communication protocol format, resolves the hardware address of the elevator main control module 27, and then sends the hardware address to the elevator main control module 27. The elevator main control module 27 controls the traction machine to make corresponding actions, thereby completing the call-in.
For another example, when the duty room interphone 55 establishes an audio session with the room interphone 54 in the room, the duty room interphone 55 sends a request signal for establishing a connection to the room interphone 54. The request signal is sent to the duty room power carrier communication module 16 in the form of an IP data packet, where the IP data packet contains the local MAC address and the local IP address of the duty room interphone 55 and the MAC address and the IP address of the room interphone 54. The watch room power carrier communication module 16 modulates the IP data packet into a power carrier signal that is sent on the second harness 82. The second room power carrier communication module 15 receives the power carrier signal on the second wire harness 82, demodulates the power carrier signal into an IP data packet, and then packs the demodulated IP data into the room network switch 42. The room network switch 42 sends the IP packet to the room interphone 54 according to the target MAC address and the target IP address, and the room interphone 54 responds to this, thereby establishing a connection between the two. After the audio session connection is established, the audio information received by the duty room intercom 55 is also packetized into an IP packet and sent to the duty room power carrier communication module 16. The following process is similar to the above process, and thus audio communication between the duty room interphone 55 and the machine room interphone 54 is realized.
Compared with the prior art, in the embodiment of the invention, the data transmitted by the power line carrier communication module is not only simple elevator monitoring data, but also the car control data, the outbound control data, the audio and video data of the elevator internet of things, the five-party talkback audio data and the video monitoring data of the duty room are subjected to IP clustering distribution and transmission, so that an elevator control data communication line, a five-party talkback transmission line and a video monitoring transmission line in an elevator traveling cable can be saved, and meanwhile, corresponding terminal equipment in the system becomes an IP network client, thereby being beneficial to the standardization and intellectualization of an elevator system.
