Problems solved by technology

[0004] At present, most elevator monitoring systems in China do not have a database, but only provide basic real-time monitoring functions and alarm functions. Such a system has poor scalability, and it is difficult to perform higher-level monitoring of elevator conditions on it. For analysis, even if the elevator monitoring system has a database, it has only developed some simple functions, such as historical record query, fault distribution, etc.

Embodiment Construction

[0044] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0045] Such as figure 1 As shown, the frame diagram of the elevator monitoring system. The present invention adopts the field bus as the communication carrier to realize the elevator monitoring system managed by the computer, the elevator is the main body to be monitored, the control center runs in the computer, and the operating condition of the elevator is monitored with the help of the computing power of the computer. When the elevator is judged to be abnormal, it can Notify the management personnel or elevator maintenance personnel through certain means to deal with the abnormality. After the elevator signal acquirer obtains the information, it needs to be packaged into a data packet and sent to the CAN bus network through the CAN bus transceiver module. On the computer...

Abstract

The invention discloses a CAN (Controller Area Network) bus-based elevator monitoring method. A CAN bus communication circuit, a main controller, a signal collection module and an alarm module are involved; the CAN bus communication circuit comprises at least one CAN controller and a CAN transceiver; the main controller is connected with the CAN bus communication circuit and can monitor a working state of an elevator; the signal collection module can collect data and realize a communication function between the signal collection module and the CAN bus communication circuit; the alarm module is connected with the main controller and can sound an alarm for an abnormal working state of the elevator.

Description

technical field [0001] The invention relates to an elevator monitoring method, in particular to an elevator monitoring method based on CAN bus. Background technique [0002] At present, most elevator monitoring systems can only target a few specific elevator models, and are not compatible with early elevators with a high failure rate, resulting in only a part of the coverage. [0003] The interfaces of the existing domestic elevator monitoring systems are generally relatively simple, and many of them are made directly by using configuration software, and the configuration software is not suitable for applications with good user interface. [0004] At present, most elevator monitoring systems in China do not have a database, but only provide basic real-time monitoring functions and alarm functions. Such a system has poor scalability, and it is difficult to perform higher-level monitoring of elevator conditions on it. According to the analysis, even if the elevator monitoring...
