DETAILED DESCRIPTION

In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

In some embodiments, as shown in Figures 1 to 4, at least one embodiment provides an anti-interference communication system for elevator networking, which includes: a car communication terminal, a machine room communication terminal and several floor communication terminals; wherein the car communication terminal is arranged in the car, the machine room communication terminal is arranged in the machine room, and each of the floor communication terminals is respectively arranged in the elevator aisle of the corresponding floor; the car communication terminal is electrically connected to the car control system to obtain the operation data of the car; when the car communication terminal establishes a wireless channel with the machine room communication terminal, the car communication terminal sends the operation data of the car to the machine room communication terminal, and the car communication terminal receives the control instructions issued by the machine room communication terminal; when the car communication terminal establishes a wireless channel with any floor communication terminal, the car communication terminal forwards the operation data of the car to the machine room communication terminal through the floor communication terminal, and the machine room communication terminal forwards the control instructions to the car communication terminal through the floor communication terminal.

In some embodiments, by adding floor communication terminals in the elevator corridor of each floor, a wireless network can be assembled in the elevator corridor to solve the problem of poor communication quality in the elevator corridor. At the same time, the floor communication terminal serves as a transfer station between the car communication terminal and the machine room communication terminal, which can ensure that the operation data of the car is uploaded to the car control system, thereby realizing real-time monitoring of the elevator operation on the cloud platform and improving the stability and safety of the elevator operation.

In some embodiments, when the machine room communication terminal fails to obtain the car operation data from the car communication terminal and the machine room communication terminal obtains the car operation data from any floor communication terminal, the machine room communication terminal determines that a communication failure occurs between the car communication terminal and the machine room communication terminal.

Specifically, since the communication terminals on each floor are respectively arranged in the elevator aisles on the corresponding floors, when the car runs to the corresponding floor, the car communication terminal is very close to the floor communication terminal at that floor, that is, the signal strength between the car communication terminal and the floor communication terminal is good, and the car communication terminal can inevitably establish a wireless channel with the floor communication terminal. However, the wireless channel between the car communication terminal and the machine room communication terminal will be disconnected due to electromagnetic interference. The car communication terminal can forward the car operation data to the machine room communication terminal through the floor communication terminal, thereby improving the anti-interference ability and accurately judging whether there is a communication failure between the car communication terminal and the machine room communication terminal.

In some embodiments, when it is determined that a communication failure occurs between the car communication terminal and the machine room communication terminal, the machine room communication terminal forwards a repair instruction to the car communication terminal through the floor communication terminal so that the car communication terminal and the machine room communication terminal can resume communication or the machine room communication terminal uploads the fault information to the cloud.

Specifically, since the car communication terminal and the machine room communication terminal are electronic devices themselves, when the wireless channel between the car communication terminal and the machine room communication terminal is disconnected due to electromagnetic interference, the car communication terminal and the machine room communication terminal cannot automatically establish a wireless channel. The car communication terminal needs to receive a repair instruction before it can try to establish a wireless channel with the machine room communication terminal again, and the communication between the car communication terminal and the machine room communication terminal can be quickly restored. At the same time, when the car communication terminal receives a repair instruction and cannot establish a wireless channel with the machine room communication terminal again, the fault information can be uploaded to the cloud in time.

In some embodiments, when the car communication terminal establishes a wireless channel with any floor communication terminal, the floor communication terminal sends the information of the current floor of the car to the machine room communication terminal.

Specifically, although the operation data of the car includes the current floor of the car, there is a certain instability in electronic equipment, and a single data source cannot guarantee accuracy. Feedback of the current floor information of the car through the floor communication terminal can ensure the diversity of data sources, realize data verification, and improve data accuracy.

In some embodiments, the machine room communication terminal compares the acquired information about the current floor of the car with the operation data of the car to determine the operation status of the car.

Specifically, when the information of the current floor where the car is located is consistent with the operation data of the car, it means that the car is operating stably. If the information of the current floor where the car is located is inconsistent with the operation data of the car, it means that the car is operating faultily.

In some embodiments, when it is determined that a fault occurs in the operating state of the car, the car communication terminal uploads the fault information to the cloud.

In some embodiments, the car communication terminal includes: a car communication gateway; the car communication gateway is arranged in the car, and the car communication gateway is electrically connected to the car control system; the car communication gateway communicates with the car control system to obtain the operation data of the car; when the car communication gateway establishes a wireless channel with the machine room communication terminal, the car communication gateway sends the operation data of the car to the machine room communication terminal, and the car communication gateway receives the control instructions issued by the machine room communication terminal; when the car communication gateway establishes a wireless channel with any floor communication terminal, the car communication gateway forwards the operation data of the car to the machine room communication terminal through the floor communication terminal, and the machine room communication terminal forwards the control instructions to the car communication gateway through the floor communication terminal.

Specifically, the car communication gateway and the car control system can realize the collection of data such as monitoring information and operation information.

In some embodiments, the computer room communication terminal includes: a computer room communication gateway; the computer room communication gateway is arranged in the computer room; when the computer room communication gateway establishes a wireless channel with the car communication gateway, the computer room communication gateway receives the car operation data sent by the car communication gateway, and the computer room communication gateway sends corresponding control instructions to the car communication gateway; when the computer room communication gateway establishes a wireless channel with the floor communication terminal, the computer room communication gateway receives the car operation data sent by the floor communication terminal, and the computer room communication gateway sends corresponding control instructions to the floor communication terminal.

Specifically, the computer room communication gateway can communicate with the cloud.

In some embodiments, the floor communication terminal includes: a floor communication gateway; the floor communication gateway is arranged in the elevator corridor of the corresponding floor; when the floor communication gateway establishes a wireless channel with the car communication gateway, the floor communication gateway receives the car operation data sent by the car communication gateway, and the floor communication gateway sends the corresponding control instructions to the car communication gateway; when the floor communication gateway establishes a wireless channel with the machine room communication gateway, the floor communication gateway sends the car operation data to the machine room communication gateway, and the floor communication gateway receives the control instructions issued by the machine room communication gateway.

Specifically, the floor communication gateway can not only communicate with the car communication gateway and the machine room communication gateway, but the floor communication gateway can also be used as a wireless module to improve the quality of wireless communication in the elevator corridor.

In some embodiments, at least one embodiment provides a communication method using an anti-interference communication system for elevator networking as provided in the above embodiments, comprising: setting a car communication terminal in the car, setting a machine room communication terminal in the machine room, and setting each floor communication terminal in the elevator aisle of the corresponding floor; the car communication terminal is electrically connected to the car control system to obtain the operation data of the car; when the car communication terminal and the machine room communication terminal establish a wireless channel, the car communication terminal sends the car operation data to the machine room communication terminal, and the car communication terminal receives the control instructions issued by the machine room communication terminal; when the car communication terminal establishes a wireless channel with any floor communication terminal, the car communication terminal forwards the car operation data to the machine room communication terminal through the floor communication terminal, and the machine room communication terminal forwards the control instructions to the car communication terminal through the floor communication terminal.
