The invention provides a network fault positioning method and device. The method includes the following steps: control plane equipment sends a first diagnostic message to a specified node in a first forwarding node set on a service path, and the control plane equipment receives a second diagnostic message fed back by a forwarding node in the first forwarding node set and determines the forwardingnode that feeds back the second diagnostic message to obtain a second forwarding node set, wherein the second diagnostic message is a message obtained by duplicating the first diagnostic message through the forwarding node in the first forwarding node set; and the control plane equipment determines the node with a network fault based on the second forwarding node set. By adopting the technical scheme, the problem that the positioning of the network fault in related technologies is high in difficulty and low in accuracy can be solved, and the process of conveniently and accurately finding out the node with the network fault can be implemented.

A method for operating a parking facility, a parking system for vehicles, and a computer program are also described.

The invention discloses a marking device for automatic moving detection of a detecting piece. The marking device comprises a frame; a vertical plate is fixed at the back part of the top surface of a top plate of the frame; an upper support plate for forwards extending is fixed at the top end of the vertical plate; upper moving support plates are fixed on two sides of the bottom surface of the upper support plate; two ends of an upper moving screw rod are hinged to the two upper moving support plates; a driving motor is fixed on the outer side wall of one upper moving support plate; an output shaft of the driving motor is a spline shaft; the spline shaft is inserted in a spline hole at one end of the corresponding upper moving screw rod; a moving block is screwed in the upper moving screw rod; and a lower support bent plate is fixed at the bottom of the moving block. The marking device is arranged in each detecting place for automatically marking each workpiece after detection to clearly know the detecting places of the workpieces, so that the previous detecting places can be conveniently searched after subsequent problems occur, the problems can be conveniently found out, and the detecting effect is improved.

The invention discloses a drilling equipment and a method for realizing bottom hole pressure control by using flow monitoring. The drilling equipment includes: mud pump inlet flow measurement system, back pressure pump inlet flow measurement system, drilling fluid return flow measurement system, automatic throttling manifold system, and rotary control head, liquid-gas separator, vibrating screen, all The inlet of the mud pump inlet flow measurement system is connected to the mud tank by a pipeline, and the outlet of the mud pump inlet flow measurement system is connected to the drill pipe by a pipeline. Through the bottom of the drill pipe, the drill bit travels from the borehole annulus to the rotary control head and connects with the automatic control unit. The inlet pipeline of the flow manifold system is connected with the outlet pipeline of the inlet flow measurement system of the back pressure pump; the inlet flow measurement system of the back pressure pump has a pipeline connected to the mud tank; the outlet of the automatic throttling manifold system has a pipeline and the return flow of drilling fluid The inlet of the measurement system is connected; the outlet of the drilling fluid return flow measurement system is connected with the inlet of the liquid-gas separator by a pipeline; the liquid-gas separator has two branches. The invention can effectively control or eliminate the bad influence caused by well bottom leakage or overflow on well drilling.
