Abstract

The utility model relates to a control system for preventing overweight vehicle from passing a bridge based on a computer, which manly solves the problem that a bridge protecting device with low cost and effective prevention and control does not exist in the prior art. The control system is characterized in that a detection and control unit comprises a detection box, a weighbridge and a detection rail controlled by the detection box; the weighbridge comprises a plurality of pressure sensors which are distributed in a rectangle; the inner part of the detection box contains a data acquisition card, an RS232 serial interface, an MCS51 single chip microcomputer, a power supply module, a memorizer, a wireless transceiver module and a motor execution circuit for driving the detection rail to act, and the data acquisition card is matched with the pressure sensors; and a control signal output by the control signal output end of the MCS51 single chip microcomputer is transferred into the motor execution circuit for driving the detection rail to act. The control system is formed by combining the wireless transceiver module with the pressure sensors through the single chip microcomputer, the production and installation cost is low, but the effective overweight preventing protection to the bridge can be realized, and the control system has strong practicality.

Description

The anti-overweight vehicle of computer based is crossed the control system of bridge

Technical field

The utility model relates to a kind of bridge protector device that makes up based on Computer Control Technology.

Background technology

The accident that occurs caving in along with domestic and abroad bridge takes place frequently, and people have begun to put into bridge protection field to more concern, to guarantee personnel's life security or property safety.Owing to consider cost factor; Can not on every bridge block, all set up artificial measuring station, so, at present; All be through the mode of warning sign is set on a lot of bridges; Promptly in the above with: forbid surpassing the printed words such as vehicle pass-through of a certain load-carrying, still, this mode is difficult to obviously effectively to realize preventing that overweight vehicle from crossing the purpose of bridge.

Summary of the invention

The technical problem of mentioning in order to solve in the background technology; The low cost control system that the utility model provides the anti-overweight vehicle of a kind of computer based to cross bridge; This kind control system can automatically test the overweight situation and the control of every vehicle and pass through, and has guaranteed the safety of bridge and vehicle.

The technical scheme of the utility model is: the anti-overweight vehicle of this kind computer based is crossed the control system of bridge; Form by detecting control module, access control unit and forbidden control module, said detection control module is made up of the detection railing of detection case, on-ground weigher and the control of examined case; Wherein, Said on-ground weigher is made up of the pressure sensor group of some rectangular distributions, comprises data collecting card, RS232 serial line interface, MCS51 single-chip microcomputer, power module, memory, the radio receiving transmitting module that matches with the aforementioned pressure sensor groups in the said detection case and drives the motor executive circuit that detects the railing action; The data of said data collecting card output are input to the pressure signal input of MCS51 single-chip microcomputer through the RS232 serial line interface; Adopt bidirectional traffic to be connected between said radio receiving transmitting module and the MCS51 single-chip microcomputer, be passed to said driving by the control signal of the control signal output output of said MCS51 single-chip microcomputer and detect in the motor executive circuit that railing moves; Said access control unit and forbidden control module are respectively by the access control case and receive the current railing and the forbidden control cabinet of its control and constituted by the forbidden railing of its control; Wherein, The composition of said access control case and forbidden control cabinet is identical, by the motor executive circuit connection back formation of MCS51 single-chip microcomputer, power module, memory, radio receiving transmitting module and the action of driving railing.

The utlity model has following beneficial effect: the anti-overweight vehicle of this kind computer based is crossed the control system of bridge; Detect the load-carrying of every vehicle through the on-ground weigher of pressure sensor composition; Be input to detected pressure value in the single-chip microcomputer then and calculate; When finding that certain vehicle load-carrying is above standard or is not above standard, just can send signal through wireless transmitter module to the wireless receiving module in forbidden control cabinet or the access control case, open thereby control corresponding railing.This kind of system adopts extremely low single-chip microcomputer of cost and wireless receiving and transmitter module structure to form; Overweight situation and the control that can automatically test every vehicle are current; Production and installation cost are extremely low, but can realize that the effectively anti-overweight protection of bridge is had stronger practicality.

The forbidden control cabinet of 1-among the figure, the forbidden railing of 2-, the 3-railing that passes through, 4-access control case, the 5-on-ground weigher, 6-detects railing, 7-detection case, 8-parking area, 9-FOH.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is described further:

Combine Fig. 2, shown in Figure 3 by Fig. 1, the anti-overweight vehicle of this kind computer based is crossed the control system of bridge, forms by detecting control module, access control unit and forbidden control module, and its unique distinction is:

Said detection control module is made up of the detection railing 6 of detection case 7, on-ground weigher 5 and the control of examined case.Wherein, Said on-ground weigher 5 is made up of the pressure sensor group of some rectangular distributions, comprises data collecting card, RS232 serial line interface, MCS51 single-chip microcomputer, power module, memory, the radio receiving transmitting module that matches with the aforementioned pressure sensor groups in the said detection case 7 and drives the motor executive circuit that detects railing 6 actions; The data of said data collecting card output are input to the pressure signal input of MCS51 single-chip microcomputer through the RS232 serial line interface; Adopt bidirectional traffic to be connected between said radio receiving transmitting module and the MCS51 single-chip microcomputer, be passed to said driving by the control signal of the control signal output output of said MCS51 single-chip microcomputer and detect in the motor executive circuit that railing 6 moves.

Said access control unit and forbidden control module respectively by access control case 4 and the current railing 3 that receives its control with forbidden control cabinet 1 and constituted by the forbidden railing 2 of its control; Wherein, Said access control case 4 is identical with the composition of forbidden control cabinet 1, by the motor executive circuit connection back formation of MCS51 single-chip microcomputer, power module, memory, radio receiving transmitting module and the action of driving railing.

With said system according to shown in Figure 1; Arrange that on bridge the on-ground weigher of forming through pressure sensor detects the load-carrying of every vehicle, is input to detected pressure value in the single-chip microcomputer then and calculates; When finding that certain vehicle load-carrying is above standard or is not above standard; Just can send signal through wireless transmitter module, open, import vehicle in FOH 9 or the parking area 8 thereby control corresponding railing to the wireless receiving module in forbidden control cabinet or the access control case.
