Abstract

The utility model relates to an anti-crossing alarm for a highway guardrail net, belonging to the technical field of safety protection and aiming at providing an alarm to avoid crossing over the highway guardrail net. The utility model adopts a vibrating detection sensor which senses produced vibration and other interference information when the highway guardrail net is crossed and obtains a vibrating signal. The obtained signal is amplified and filtered, and then is sent to a single chip computer processing unit, the ADC of the single chip computer carries out collection and analysis, compares and analyzes the signal with stored database information in a fuzzy recognition way, and filters the interference signal, thus alarming accurately according to the produced vibration when the highway guardrail net is crossed. The alarm is used for preventing people from crossing the highway guardrail net, has positive function for protecting safe operation of the highway and reducing the crossing of unrelated people, thus leading to more fluent highway, preventing a person who crosses from life danger and easing the labor intensity of the staff of a highway group who is on duty according to determination posts.

Description

The anti-climb warning device of freeway guardrail net

Technical field

The utility model belongs to the security precautions technology field, particularly relates to the anti-climb warning device of a kind of freeway guardrail net.

Background technology

Increase along with China's highway mileage, highway inevitably need pass through some villages, some villages on the way are divided into two halves by highway, cause the inconvenience of both sides people-to-people contacts, because people are thin to the consciousness of traffic law, just there is artificial figure convenient again, ignores self life security unexpectedly and remove to cross freeway guardrail net, while is also jeopardized the security of the lives and property the driver and crew of the vehicle of highway cruising, and the tragedy that leads to thus is of common occurrence.For example near the service area of peaceful logical highway Yizheng, just the generation personnel cross time and again, and rather logical high speed group has to take the behave on duty of determining a post, and tells everybody, and this behavior also belongs to the break in traffic rules and regulations behavior.In order to prevent to cross freeway guardrail net, invent the anti-climb warning device of a kind of freeway guardrail net and just seem very necessary.

The utility model content

The purpose of this utility model is to provide a kind of freeway guardrail net anti-climb warning device.

Must follow physical features such as vibration, impact to produce to the process of crossing of freeway guardrail net, in addition, when having heavy truck to pass through at a high speed on the highway, on freeway guardrail, also can produce some vibration, form undesired signal, in order to make the anti-climb warning device of each freeway guardrail net can when enlarging protective range, not produce false alarm as far as possible, must eliminate undesired signal.

The utility model is installed on the column of freeway guardrail net, in the certain distance scope, dependence is installed on the vibration detection sensor of the utility model inside, experiences vibration and other interfere information that crossing of freeway guardrail net produced, obtains vibration signal.Vibration detection sensor of a great variety, to pick up feeble signal relatively sensitive acceleration transducer arranged, the piezo crystal vibration transducer, indium stibide film reluctance type vibration transducer etc., the utility model is selected high sensitivity piezo crystal vibration transducer more cheap and easy to get for use, its sensitivity is more than 2000pC/g, the signal that is obtained is through amplifying, send into the single-chip microcomputer processing unit after the filtering, gather and analyze by the ADC in the single-chip microcomputer, utilize the method for fuzzy diagnosis and stored database information to compare analysis, further filter out undesired signal, thereby report to the police accurately.The utility model also comprises 485 bus transfer chips, and each warning device all has independently recognition coding, can be sent to Surveillance center to warning message by the networking of 485 buses where necessary.

Type of alarm of the present utility model has two kinds: the anti-climb warning device of freeway guardrail net scene is sent chimes of doom and is warned to threaten the personnel of crossing and to remind on-the-spot security personnel, simultaneously can also warning message be sent to Surveillance center by 485 buses, display alarm place and automatic recording-related information, and deposit in the information bank so that carrying out warning message consults afterwards, constitute a complete warning system.

The utility model is applied to freeway guardrail net and crosses to prevent personnel; safe operation to the protection highway; the minimizing unrelated person is crossed has positive effect; can not only make highway more unobstructed; can also pre-anti-climb personnel produce life danger, alleviate the high speed group working strength on duty of determining a post.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

The anti-climb warning device of Fig. 1 the utility model freeway guardrail net constitutes synoptic diagram;
