The invention discloses a derailment monitoring system of endless-rope continuous towing vehicles and a monitoring method of the derailment monitoring system. An inductance type proximity switch of the derailment monitoring system is installed on a shuttle car; the shuttle car is provided with an emitter; the emitter is connected with the inductance type proximity switch; the emitter emits detection signals of the inductance type proximity switch; a router is installed at one side of a tunnel; the router receives the detection signals emitted by the emitter and transmits the detection signals to a receiver; the receiver is connected with a PLC processor through a bus; the PLC processor is connected with a display screen; the PLC is also connected with a relay; and the relay is connected with a control switch of a winch. With the monitoring method of the derailment monitoring system adopted, the position of the shuttle car can be positioned in real time, and the operation state of the shuttle car can be judged, and if a sensor predicts derailment, alarm signals can be generated, and the motor of the winch can be locked, and therefore, major accidents can be avoided, and efficient and safe operation of a coal mine auxiliary transportation system can be ensured; and derailment prediction information and shuttle car position information can be combined together, so that fault points can be found timely, and therefore, maintenance and repair can be performed.

The invention relates to a fuel cell power system monitoring technology. The invention particularly relates to a fuel cell power system platform upper computer monitoring method based on a CAN bus. Anupper computer is connected to a fuel cell controller, a DC/DC and a CAN network of an adjustable load through a CAN bus. A parallel processing multi-thread structure is adopted to receive messagesof the DC/DC, the adjustable load and the fuel cell controller, and display real-time data and curves and stores data of parameters and states of the DC/DC, the adjustable load and a fuel cell engine.The messages are sent to the fuel cell controller and the adjustable load by operating function buttons on an interface of the upper computer and setting control target values of related components,and then manual control, automatic control and forced manual control are conducted on the fuel cell power system platform. According to the method, state monitoring and energy control strategy debugging of the fuel cell power system platform are facilitated, the anti-interference capability is high, and the control performance is stable.

The invention provides a safety measure intelligent management method. The safety measure intelligent management method comprises the following steps: S1, establishing a specific dictionary of each transformer substation; S2, segmenting statements on the work ticket information by adopting a dictionary matching algorithm to obtain segmentation results; S3, preprocessing the segmentation result toobtain a safety measure arrangement guide; and S4, sending a visual safety measure arrangement notification according to the safety measure guidance. The invention further provides a safety measure intelligent management system. The safety measure intelligent management system comprises the intelligent safety measure device, an Internet of Things communication system, a monitoring analysis system,a storage module and a display terminal. According to the invention, by segmenting work ticket information through employing a dictionary matching algorithm, and carrying out the preprocessing of a segmentation result to obtain a safety measure arrangement guide, an operator arranges a safety measure according to the safety measure arrangement guide. The problem that a large amount of time is consumed for arranging safety measures at present is solved.
