Problems solved by technology

When in use, someone needs to be on duty, manually control the power supply, the motor rotates to drive the gear set, and the gear set drives the movement of the railing. Generally, it is in a normally closed state, and the cost of use is high. It is not suitable for underground passages. The underground passage railing machine should be in a normally open state. Does not require frequent operation of controls

Abstract

The invention discloses a secondary accident preventing method for an underground tunnel. The secondary accident preventing method for the underground tunnel includes the steps of firstly, acquiring length L and annual average daily traffic Q of the underground tunnel; secondly, classifying traffic engineering according to the annual average daily traffic Q; thirdly, determining distribution of rails according to the length L of the underground tunnel and traffic engineering classification. The traffic engineering classification is determined according to the length L and annual average daily traffic Q of the underground tunnel, and thereby distribution or not of the rails at an entrance of the underground tunnel is determined. Vehicles are prevented from entering the abnormal underground tunnel, and accordingly secondary accidents are avoided.

Description

technical field [0001] The invention relates to a control method for a railing that restricts the free passage of vehicles, in particular to a method for preventing secondary accidents in an underground passage. Background technique [0002] Researches at home and abroad show that when an abnormality occurs in an underground passage, secondary accidents are likely to occur, and the main reason is that the vehicle enters the abnormal underground passage. At present, there are no railings dedicated to underground passages. The railings commonly used are mainly railing machines for expressway toll stations and railing machines for toll parking lots, which are mainly composed of motors, railings, gear sets, connectors, and controllers. When in use, someone needs to be on duty, manually control the power supply, the motor rotates to drive the gear set, and the gear set drives the movement of the railing. Generally, it is in a normally closed state, and the cost of use is high. It...
