The invention provides an intelligent anti-error analysis method and system, providing an ''intelligent'' application for drawing up tickets. The method and system can realize ''one-button'' intelligent ticket issue by regulation and control personnel, standardize ticket issue terms, shorten ticket drawing-up time, mitigate the workload of the regulation and control personnel, and increase the work efficiency of the regulation and control personnel. The method and system meanwhile monitor intelligent operation of drawing up tickets, and safe related functions in operation ticket processes, and provide safe related functions of remote control for real-time monitoring and early warning. The method and system can automate the work of dispatchers and monitors, substantially reduce the workload of the dispatchers and monitors, increase work efficiency, and reduce safety risk.

The invention discloses an intelligent safety control system and vehicle. The intelligent safety control system comprises multiple distance sensors for detecting the distances of front and back obstacles, an engine ECU, an intelligent module and a brake assisting motor, wherein a control list is stored in the intelligent module and records corresponding relation between the allowed accelerator value and current speed, current gear and obstacle distance as well as the start conditions of brake assistance; when synchronous accelerator signal and brake signal are detected, the intelligent module is used for obtaining the distance, speed and gear and then determining the allowed accelerator value and whether the braking assistance is needed according to the control list and sends corresponding signals to the engine ECU; and the engine ECU executes corresponding control. The intelligent safety control system and the vehicle disclosed by the invention can guarantee the driving safety to the greatest degree and effectively eliminate the safety risk of the driver stepping on the accelerator pedal by mistake, thereby avoiding serious accidents of vehicle collision.

The invention discloses a construction method for integral hoisting of a large-span steel trussed beam. The construction method includes the following steps: (1), selecting a suspension center for integral hoisting of the large-span steel trussed beam, (2), designing and constructing a hoisting tool, and (3), constructing for integral hoisting. The construction method has the advantages that the steel trussed beam is erected through integral hoisting under a navigation condition, and the construction method is simpler in operation and easier in accuracy control as compared with a method in which the steel trussed beam is constructed through less-support segmentation assembly and floating support; safety risk of operations at sea is reduced, construction period is shortened, and construction cost is reduced.

The invention discloses an automatic convertor for ride sharing passenger carrying displaying, and belongs to the field of ride sharing passenger carrying displaying devices. The automatic convertor for ride sharing passenger carrying displaying comprises an automatic skip indicator, multiple sensing foot pads are connected to the automatic skip indicator through first connecting lines and arranged on the lower front sides of seats in a car, each foot pad is composed of a first connecting pad, a second connecting pad and a pressure sensor, each pressure sensor is located between the corresponding first connecting pad and the corresponding second connecting pad, and buffer springs are connected between each first connecting pad and the corresponding second connecting pad. According to the automatic convertor, a passenger can conveniently stop the car, a car owner does not need to operate a mobile phone for order receiving, quick order receiving and ride sharing can be conducted through the automatic skip indicator, and safety risks are effectively avoided.

The invention discloses a water seal device for gas cutting in and out and a use method thereof. The water seal device comprises an outer cylinder and an inner cylinder, wherein a sealed chamber is defined by the outer cylinder; a gas outlet pipe communicating with the chamber is arranged at the upper end of the outer cylinder; a gas inlet pipe communicating with the chamber is arranged at the lower end of the outer cylinder; a water inlet pipe communicating with the chamber is arranged on one side of the outer cylinder for allowing water to flow into the chamber; an overflow pipe communicating with the chamber is arranged on the other side of the outer cylinder for detecting the level of the water in the chamber; a water drainage pipe communicating with the chamber is arranged at the bottom part of the outer cylinder; the inner cylinder is arranged in the chamber; the inner cylinder defines a working chamber with an opened lower end out; and the chamber communicates with the working chamber. According to the water seal device for gas cutting in and out and the usage method thereof, which are shown in the embodiment of the invention, the water seal device is adopted for controllingthe gas to be cut in and out, thereby not only being convenient in operation and reducing the operation procedures, but also having good controlling effect in cutting the gas in and out and eliminating the safety risk.
