[Technical field to which the invention pertains]

The present invention relates to a monitoring of the condition of a bridge in the prior art. A bridge monitoring system, in particular, a system type of reaction processing. - Kindly can be pressed, Taiwan's island has a very frequent board, the autumn season usually has more things flow, the water brings flooding shocks and labor reduction, reducing the bridge inconvenience. The bridge piers are caused by each other, and then the degree must be repaired. First, if the bridge is government, the local government will receive the people’s casualties if the people do not go up, and the damage will not make up for the damage. After the natural disaster, the damage of the bridge will collapse, and the earthquake zone where people are in the Eurasian plate and the Philippine block is subjected to many typhoons, and the bridge is hitting, plus The life of the bridge itself is prone to break. The general practice is to follow the traces, such as the displacement on the bridge surface and not the horizontal state. The level detector is used to measure the work, but this kind of practice can damage the 'most of them. After receiving the report, it will be sent to Shi Ying, and no one will make the place unnecessary. It is still the biggest victim. The general public is more local government. It has not been dispatched to become more and more serious. It is easy to form a beautiful Weibin board at the junction of the bridge, and it is in the area, and in the summer, plus the Taiwan rivers are full of earthquakes or hurricane households, poor design and cracking damage. After affecting traffic earthquakes or hurricanes, serious cracks may occur. 'The bridge surface is unevenly affected by the uneven displacement of the piers. It is easy to produce a large number of people. ♦ Tell the local workers to make repairs. The people have been subjected to the second, the destruction of the bridge can not be known to strengthen the patrol with the upward rebels, and the threats when there are people and cars on the back.

Rc is used for charging. When there is no capacitor, the capacitor starts to discharge to the transistor. Because the output current is too small to drive the relay, the transistor is used to amplify the current to drive the relay.

As shown in Fig. 5, a schematic diagram of an embodiment of a laser sensor is arranged on a board and is covered with sensors. The sensor is laterally juxtaposed in three groups in the present invention. For example, the fifteen groups are arranged vertically, but not limited to this number, which can be set to a larger number of groups as required, and the sensor is disposed in the same group of horizontally juxtaposed sensors. After receiving the laser light, the detector sends the same signal to the comparator and the controller, so that the radiation receiving range of the laser light can be increased, and the initial illumination point of the laser light is set at X 0 to a degree of 0 ( As shown in Figure 5-1), after the first year, the irradiation is formed at a, we can measure the relative subsidence to XI (Figure 5-2), and the second year is formed at 2a (Figure 5). -3), we can measure the relative subsidence degree as X 2, and so on. The η year illumination is na, and the degree of subsidence is Χη, which can predict the degree of subsidence at η+1 years, in order to notify the monitoring center. Make repairs as soon as possible. As shown in Fig. 6, the laser sensor of the present invention is installed in the bridge

Page 9 1310898 V. Description of the invention (6) The output module is activated by receiving the transmitted command, the gate control switch, and the voice loading flow chart as shown in Fig. 10, by the above-mentioned components, when the bridge surface is recessed The laser sensor of the uneven or bridge pier is judged by the comparator and then the strain gauge sensor uses the signal of the resistance change amount, and the A/D converter 'via the A/D to the controller, via the controller. The output module is activated and the counter is used to calculate the bridge surface car: Heavy danger, and the voice can be used to activate the gate to close the bridge deck pc so that the personnel can monitor the condition and control the effect at any time to make it safe.

[Explanation of Advantages of the Invention] The signal after the controller judges, according to the warning and protection function system displayed by the signal, such as: setting, LED subtitle display and counter (moving) and other devices. When the laser sensor and the strain gauge sensor sense the exposure to a certain degree and are in danger, the displacement sensing signal from the laser pen is received, and the generated signal is sent to the controller, and the strain gauge is received. The fork-to-vibration strain is amplified by the amplifier's amplifier circuit and transmitted to the controller. The signal is sent to the controller to send the signal to the wheel-out module to control the alarm and protection function system, such as: Have hunger =: make traffic control, so as to avoid the load over = subtitles kanban to warn the situation, then ban the traffic, and then send the signal to, in order to achieve real-time monitoring of the bridge situation, that is, the disaster can be minimized, Safeguarding the human car's when the laser sensor and the strain gauge bridge pier are exposed to a certain extent and there is danger of receiving the signal from the laser pen, the signal generated is sent to the control.

By the setting of the bridge monitoring system, when the bridge deck is sensed to be uneven or the sag, the laser sensor is nicknamed and then judged by the comparator.

1310898 V. Invention description (7), and the strain gauge change causes the resistance quality change to be transmitted to the A/D conversion signal and sent to the controller, 'to control the output module: having a counter to calculate the load overload risk, and 'Re-start the transmission to the PC to enable the personnel to respond to the situation and handle the safety of the vehicle. After receiving the strain gauge, after the amplifier converts the signal, it will send the signal and then pass the signal to the warning and protection work & quantity to make the flow &#幕板board to prohibit the passage of the vehicle, : The occurrence of the X damage can be reduced to the signal of the variable using the variable system and then activated by the A/D via the controller column to display the effect of monitoring the condition when the bridge surface of the bridge vehicle can close the bridge through the voice door, so that the circuit to the vibration should be enlarged. To the controller will turn to the module to enable the system, such as regulation, so as to avoid warnings and monitor the bridge at the lowest signal, guarantee
