Background
At present, in domestic markets, an electric control system of a tower crane (hereinafter referred to as a tower crane) rarely carries out comprehensive fault monitoring on each part of the tower crane. The common fault monitoring system of the tower crane is an online monitoring system of a third party, monitors specific equipment, and has the defects of incomplete monitoring and fuzzy fault diagnosis. The third-party monitoring system is independently arranged with the tower crane control system and is responsible for collecting sensor signals in a centralized manner and processing the sensor signals in a centralized manner, and the third-party monitoring system is also connected with the tower crane controller through communication, collects fault information in the tower crane controller and feeds part of signals back to the tower crane controller. Most of fault information acquired by the monitoring system is not used for control logic judgment of the tower crane controller, and is only used for fault information display and voice alarm. The tower crane controller needs to additionally collect mechanical limit switch signals of each mechanism and carry out safe logic control. The signal needs to be collected and processed in a centralized mode, external cables need to be collected in one cabinet, wiring is complex, signal wires outside the cabinet are long, and signal detection errors or misoperation are prone to being caused due to cable damage. If the tower crane is subjected to comprehensive fault detection, a large amount of signal feedback is needed, and a large amount of IO interfaces are difficult to provide by a related fault detection method, so that only relatively more important equipment can be subjected to fault monitoring. The tower crane control system depends on a mechanical limit switch, the mechanical limit switch is easy to generate the conditions of misoperation, insensitive action and the like when being polluted, aged or in a vibration state, and related technologies can not diagnose whether the limiter has faults or not, so that the safety risk exists. Therefore, a distributed tower crane electric control system with online fault diagnosis is developed, a large number of IO interfaces can be provided without a large number of external cables, fault monitoring of all devices of the tower crane is achieved, fault diagnosis can be performed on the limiter, accurate fault positioning is guaranteed, fault diagnosis results are detailed and comprehensive, and the technical problem to be solved in the industry is solved urgently.

Specifically, tower machine electrical control system can be divided into 2 or more than 2 cabinets according to the size and how much of equipment, and each cabinet body is close to mainly by the mechanism controlled or detected, contains distributed IO controller in every cabinet body, and its main function is: collecting state signals of an external mechanism, such as brake limit switch signals and the like, and collecting action signals of devices in a cabinet, such as switch states of devices such as a contactor, a breaker and the like; running state signals, such as running states of frequency converters and the like; transmitting various collected signals to a tower crane control module through an industrial bus; and controlling related operations according to the devices in the cabinet and the mechanisms outside the cabinet of the tower crane control module, wherein if the tower crane control module sends a closing signal of a certain contactor, the appointed distributed IO controller receives the communication signal, controls the contactor to act through the output port of the distributed IO controller, collects the state of the auxiliary contact of the contactor, and reports whether the contactor acts correctly or not to the tower crane control module. It should be noted that the distributed IO controllers are installed in one-to-one correspondence with the cabinet bodies of the cabinets, if there are a plurality of cabinets, there are a corresponding number of distributed IO controllers, and one distributed IO controller is installed in each cabinet.

It should be noted that the premise of the fault online diagnosis is that the operation state of each device of the tower crane can be comprehensively monitored, a large amount of monitored data is taken as a basis, and the data is analyzed and judged, so that the fault online diagnosis is realized. For example, in a motor control loop, an IO controller detects that an auxiliary contact of a motor protection circuit breaker is closed, an auxiliary contact of a motor control contactor is closed, state information such as disconnection of an auxiliary contact of a thermal relay is obtained, the IO controller reports the state information to a main controller and an industrial computer, the industrial computer analyzes information such as continuous operation time of a motor, load change conditions in the operation time, temperature rise conditions of the motor and the like, and then judges whether the motor continuously operates too long or the motor is overheated due to overload operation, so that the thermal relay acts, or the motor operates normally, and the thermal relay breaks down.

Not only can each device be monitored, but also the device can be accurately positioned when the device fails, so that the fault finding time is reduced, the utilization efficiency of the device is improved, and the service life of the device is prolonged; and the system can also provide detailed environmental information for the control system, so that the tower crane can run in a safer environment. The process of information acquisition and analysis is also the process of fault diagnosis, and the signals can be divided into the process of influencing the normal production operation of the tower crane and the process of not influencing the normal production operation of the tower crane by a control system; signals influencing the normal operation of the tower crane can directly participate in the control logic judgment. The state signals of the electronic sensor and the mechanical limiter are added into the control logic judgment at the same time, so that mutual state check and mutual fault check are formed, double guarantee is achieved, whether the mechanical limiter or the electronic sensor fails or not can be diagnosed in time, misoperation of the mechanism is effectively prevented, and potential safety hazards are eliminated. Adopt distribution IO control module and tower machine control module to be connected, through the industrial bus communication between each cabinet body, reduce the external equipment cable, improve the reliability.
