Embodiments of the invention

The embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

Reference will now be made in detail to the preferred embodiments embodiments embodiments Numerous specific details are shown in the following detailed description in order to provide a It will be apparent to those skilled in the art, however, that the various described embodiments may be practiced without the specific details. In other instances, well-known methods, procedures, components, circuits, and networks are not described in detail so as not to unnecessarily obscure the embodiments.

[0027] Embodiment 1

1 is a flowchart of a sensor-based road bridge state monitoring method according to Embodiment 1 of the present invention.

As shown in FIG. 1, the sensor-based road bridge state monitoring method specifically includes the following steps S101 to S1 03.

[0029] Step S101: Acquire first data collected by the sensor, where the sensor is located at a preset position of the road bridge, and the number of the sensors is greater than a minimum number of sensors required to monitor the state of the road bridge.

[0030] wherein, the preset position is set according to the monitoring requirement, and the sensor in the preset position monitors each monitoring indicator of the road and bridge state, and collects the first data, and the first data includes the corresponding monitoring index. Data (such as pressure value, temperature and humidity value), type of sensor, and position information of the sensor, the position information may be in the form of a label, for example, A3 may be used to represent the third sub-area of the road bridge A area. The sensor can be one type or multiple types. Correspondingly, it may be a plurality of monitoring indicators for monitoring the state of the road and bridge; or a monitoring indicator corresponding to the state of monitoring the road and bridge, that is, each of the sensors respectively corresponding to monitoring the state of the road and bridge; The number of sensors and other corresponding monitoring relationships of the corresponding number of monitoring indicators (for example, one of the plurality of sensors corresponds to monitoring two of the plurality of monitoring indicators). Among them, the number of sensors (including the case of only one type of sensor) is greater than the minimum number of sensors required to monitor the state of the bridge. Preferably, the number of sensors can be much larger than the minimum number. For example, the minimum number is 1000, correspondingly, far more than 3,000. The premise of the above preset position setting and the coverage of the sensor position is that the comprehensiveness of the road and bridge state monitoring can be ensured.

[0031] In the embodiment of the present invention, the number of sensors (including the case of only one type of sensor) is greater than the minimum number of sensors required to monitor the state of the bridge, which makes the monitoring of the state of the bridge not subject to the operation of some sensors. The effect of the state, thus avoiding the secondary construction caused by the repair or replacement of the sensor in an abnormal working state.

[0032] Step S102: Send the second data that meets the preset condition in the first data to the server, where the preset condition is that the collection time is in a preset time range or the data value is out of a preset range.

[0033] The sensor may collect the first data periodically, and correspondingly, the sending of the data may also be implemented by means of periodic transmission. Referring to Figure 2, the data acquisition interval is 1 second, and the data transmission interval is 1 second. The preset time can be the data transmission interval, and the second to third seconds are one of the preset time periods, during which data is collected and transmitted; the third to fourth seconds are not presets. Therefore, the data is not sent; the 5th to 6th seconds is one of the preset times, during which data is transmitted, but only the data sent is collected from the 5th to 6th seconds of the sensor. In order to avoid overlapping with the data transmitted from the second to third seconds described above, repeated transmission is caused. Therefore, the preset time can be from 2 seconds to 3 seconds and from 5 seconds to 6 seconds, and the preset conditions are not satisfied during the interval in which data is not required to be transmitted, such as 1st, 4th, and 7th. . For convenience of description, the unit in Figure 2 is used for 1 second. It can be understood that the actual application can be adjusted according to the monitoring needs, for example, the unit is adjusted to 10 seconds or 1 minute.

[0034] The preset range may be different in different turns, such as pressure value, humidity value, temperature value, etc. Historical statistics are available. It can be understood that the second data in the first data that exceeds the preset range is sent only when the collected first data exceeds the preset range.

In the embodiment of the present invention, only transmitting the second data that meets the preset condition in the first data can greatly reduce the data that is not related to the monitoring of the road bridge state, and can improve the efficiency of data transmission.

[0036] Step S103: Determine a trend of the monitoring indicator of the road and bridge state according to the second data, and match the trend of the monitoring indicator with a preset standard model, and if the matching fails, the early warning notification.

[0037] As can be seen from the description in step S102, the second data is valid data that can reflect the trend of the monitoring index of the road bridge state. Based on these valid second data, they are analyzed to obtain trends in monitoring indicators. It can be understood that the trend of monitoring indicators here may be an overall trend of road and bridge states formed by various monitoring indicators, or a trend of individual monitoring indicators. Correspondingly, the notification is made according to a preset standard model. For example, when the trend of a single monitoring indicator matches the preset standard model, if the matching fails, the warning notification is sent; or the overall trend of the road and bridge state is matched with the preset standard model, and if the matching fails, the warning notification is The trend of a single monitoring indicator does not need to match the preset standard model, nor is it a separate warning notification; it can also be that the trend of a single monitoring indicator matches the preset standard model. If the matching fails, the warning notification, the overall state of the road and bridge The trend matches the preset standard model, and if the match fails, the notification is also alerted.

[0038] In summary, the sensor-based road and bridge state monitoring method provided by the embodiment of the present invention collects the first data by using a minimum number of sensors located at a preset position of the road bridge than the sensor required to monitor the state of the road bridge, and will be first. The second data in the data that meets the preset condition is sent to the server; the trend of the monitoring indicator of the road and bridge state is analyzed according to the second data, and the trend of the monitoring indicator is abnormal, and the warning notice is used to solve the monitoring cost of the existing road and bridge state monitoring technology. High, low monitoring efficiency; Sensors in the preset position of the road bridge ensure the comprehensiveness of the monitoring results, each type (including the case of only one type of sensor) The number of sensors is greater than the minimum number of sensors required to monitor the state of the bridge, this The monitoring of the state of the road and bridge is not affected by the working state of some sensors, avoiding the secondary construction and the monitoring cost and low efficiency caused by the secondary construction, the monitoring cost is low and the monitoring efficiency is high.

[0039] Embodiment 2

[0040] On the basis of the first embodiment, preferably, the sensor includes a plurality of types, each of the sensors corresponding to one of the monitoring indicators for monitoring the state of the road bridge; the number of the sensors is monitoring Place A multiple of the sum of the minimum number of sensors required for each monitoring indicator of the road and bridge state.

[0041] For example, various sensors include: a temperature sensor, a humidity sensor, a slope sensor, a displacement sensor, a pressure sensor, and a crack sensor. These sensors monitor the temperature monitoring indicators, humidity monitoring indicators, slope monitoring indicators, displacement monitoring indicators, pressure monitoring indicators and crack monitoring indicators in the monitoring indicators, so that the monitoring of the road and bridge status is more comprehensive. At the same time, the one-to-one monitoring relationship of one of the monitoring indicators corresponding to the monitoring of the state of the road and bridge is convenient for collecting, classifying and processing the data, which is beneficial to the abnormality of the monitoring index. Accurately find the corresponding sensor, thus avoiding cumbersome troubleshooting. In order to further ensure that the monitoring of the state of the road bridge is not affected by the operating state of some of the sensors, the number of the sensors is a multiple of the sum of the minimum number of each sensor required to monitor the monitoring indicators of the road and bridge state. .

Embodiment 3

On the basis of the second embodiment, as a third embodiment of the present invention, FIG. 3 is a flowchart showing a specific implementation of the sensor-based road bridge state monitoring method step S103 according to the first embodiment of the present invention. Step S103 specifically includes the following steps S301, S302, and S303.

[0044] Step S301: Clustering data collected by the same sensor in the second data to obtain cluster data.

[0045] It can be seen from step S101 that the first data includes data of a corresponding monitoring indicator (for example, a pressure value, a temperature and humidity value), a type of the sensor, and position information of the sensor. Obviously, the second data also includes data of the corresponding monitoring indicators (such as pressure value, temperature and humidity value), the type of sensor, and the position information of the sensor. It can be seen from the description in the third embodiment that each of the sensors corresponds to one of the monitoring indicators for monitoring the state of the road and bridge, that is, there are several types of sensors corresponding to the road and bridge state monitoring indicators. Therefore, after performing trend analysis on various indicators of the road and bridge state, it is only necessary to cluster the second data of the specific type of sensors in the second data, and then perform trend analysis. It should be understood that, according to actual needs, the second data of all kinds of sensors may be clustered separately, and then the trend indicators of the road and bridge are separately analyzed. The method is applicable to trending all the monitoring indicators of the road and bridge state. Analyze to monitor the overall trend of the road and bridge state; it is also possible to first cluster and filter out the second data of one or a part of the sensors, and then analyze the trend of the road and bridge monitoring indicators separately, which is applicable to the road and bridge state monitoring indicators. Targeted trend analysis of one or several monitoring indicators [0046] Step S302: Perform clustering analysis on the clustering data to obtain trends of various monitoring indicators of the road and bridge state.

[0047] clustering data obtained by clustering based on data collected by the same sensor in step S301, for example, corresponding to five different kinds of sensors, the obtained cluster data is sequentially the first cluster data, the second cluster Class data, third cluster data, fourth cluster data, and fifth cluster data. According to actual needs, the above five cluster data may be selected to perform one or more combinations in any combination for aggregation analysis, and information analysis and prediction are performed on corresponding monitoring indicators of the road and bridge state monitored by the types of sensors. For example, suppose there are five kinds of sensors, B, C, D, and E, and the first cluster data, the second cluster data, the third cluster data, the fourth cluster data, and the fifth cluster data are sequentially used & , b, c, d, and e are indicated. It can be understood that, in the actual monitoring process, only the second data of the sensor A can be clustered according to the monitoring requirement, and the trend of the monitoring index of the road bridge corresponding to the monitoring of the sensor A is obtained. The second data of sensors B and C can be clustered according to the monitoring requirements, and the trends of the monitoring indicators of the road bridges corresponding to the sensors B and C are obtained. It is also possible to cluster the second data of the sensors A, B, C, D and E of the sensor in turn according to the monitoring requirements, and sequentially obtain &, b, c, d and e, and then a, b, c, d and e perform overall analysis and prediction to obtain the overall trend of road and bridge status.

[0048] Step S303: matching a curve corresponding to the trend of the monitoring indicator with a curve corresponding to the preset standard model, if the curve corresponding to the trend of the monitoring indicator is placed in the same coordinate as the curve corresponding to the preset standard model. If the deviation degree between the curve corresponding to the trend of the monitoring index and the curve corresponding to the preset standard model is greater than the preset threshold 吋, it is determined that the trend of the monitoring indicator fails to match the preset standard model. ; If the match fails, the notification is notified by message.

[0049] FIG. 4 is a view showing a comparison of a curve corresponding to a trend of a monitoring index and a curve corresponding to a preset standard model. Referring to Figure 4, Q represents the trend, and T represents the daytime. In the inter-segment T1-T2, the trend corresponding to the trend of the monitoring index is fl, and the curve corresponding to the preset standard model is f0. The fl is compared with f0. If the deviation degree between fl and f0 is greater than the preset threshold 则, it is judged that the trend of the monitoring index fails to match the preset standard model. The preset threshold can be set according to actual needs.

[0050] wherein, the warning notification is performed by means of a message, so that the relevant personnel can take relevant measures after receiving the early warning notification. The way the message is sent can be customized. It can be a single monitoring indicator. The police notice may also be an abnormal warning of the overall trend of the road and bridge state (only a single monitoring indicator is abnormal, no warning notice is given), or it may be an early warning notification of certain related monitoring indicators. It can also be a way to trigger an alert notification based on other conditions that are customized to the actual needs.

[0051] In the embodiment of the present invention, the monitoring and trend analysis of various monitoring indicators of the road and bridge state can be flexibly performed: it may be a trend of separately analyzing one monitoring index, or may be analysis of several of the monitoring indicators ( Not including all) Trends in monitoring indicators can also be trends in the analysis of all monitoring indicators.

Embodiment 4

[0053] On the basis of the third embodiment, as a fourth embodiment of the present invention, in order to determine whether the monitoring indicators of the bridge state are really abnormal, FIG. 5 shows the sensor-based road bridge state provided by the third embodiment of the present invention. Flow chart of the monitoring method. As shown in FIG. 5, the sensor-based road bridge state monitoring method specifically includes the following steps S401 to S406.

[0054] Step S401: Acquire first data collected by the sensor, where the sensor is located at a preset position of the road bridge, and the number of the sensors is greater than a minimum number of sensors required to monitor the state of the road bridge.

[0055] The execution process of step 401 is similar to the execution process of step 101 shown in FIG. 1, and details are not described herein again.

[0056] Step S402: Send the second data that meets the preset condition in the first data to the server, where the preset condition is that the collection time is in a preset time range or the data value is out of a preset range.

[0057] The execution process of step S402 is similar to the execution process of step 102 shown in FIG. 1, and details are not described herein again.

[0058] Step S403: Clustering data collected by the same sensor in the second data to obtain cluster data.

[0059] The execution process of step S403 is similar to the execution process of step S301 shown in FIG. 3, and details are not described herein again. [0060] Step S404: Perform clustering analysis on the cluster data to obtain various states of the road and bridge state. Monitor trends in indicators.

[0061] The execution process of step S404 is similar to the execution process of step S302 shown in FIG. 3, and details are not described herein again.

[0062] Step S405: Matching the curve corresponding to the trend of the monitoring index with the curve corresponding to the preset standard model, if the curve corresponding to the trend of the monitoring index is placed in the same coordinate as the curve corresponding to the preset standard model Performing an alignment, wherein the deviation degree between the curve corresponding to the trend of the monitoring index and the curve corresponding to the preset standard model is greater than a preset threshold 吋, and determining the trend of the monitoring indicator and the preset target The quasi-model match fails; if the match fails, the notification is notified by message.

[0063] The execution process of step S405 is similar to the execution process of step S303 shown in FIG. 3, and details are not described herein again.

[0064] Step S406: When the trend of the monitoring indicator is abnormal, the monitoring frequency of the sensor corresponding to the monitoring indicator is increased.

[0065] When the trend analysis in the monitoring index is abnormal, for example, after analyzing the monitoring indicators of the road and bridge state and finding that the humidity monitoring index is abnormal under the same climatic environment in the same period, the monitoring frequency of the humidity sensor can be increased. Referring to Figure 2, when the humidity monitoring index is abnormal, the monitoring frequency of the humidity sensor can be increased, that is, the frequency at which the humidity sensor collects the first data is increased. For example, you can adjust the interval between preset turns to 1 second to 0.5 seconds or 0.1 second. After increasing the frequency at which the humidity sensor collects the first data, more second data can be further obtained and the second data is judged by the server, so that it can be quickly determined whether the humidity monitoring index is a true abnormality. If the humidity monitoring index is abnormal, it can further analyze the location of the humidity sensor that has caused the abnormality in the road bridge and make relevant warning notice.

[0066] In the embodiment of the present invention, by increasing the monitoring frequency of the sensor corresponding to the abnormal monitoring index, obtaining more data and performing trend analysis again, thereby determining whether the abnormal monitoring index is really abnormal, and improving the trend analysis of the monitoring index. The accuracy of the results. In addition, since only the monitoring frequency of the sensor corresponding to the abnormal monitoring index is increased, the pertinence is strong and the processing efficiency is higher.

[0067] Embodiment 5

[0069] While the daytime weather sensor is powered by solar energy, the sensor in the sun collects and transmits the first data while the sensor in the shadow sleeps. As the sun moves, different sensors receive sunlight at different times of the day, where sensors in the shadow zone stop collecting and transmitting the first data, while other sensors illuminated by the sun collect and transmit the bridge state. Corresponding monitoring indicators. Occasionally, the transmission of the first data may be interrupted by the occlusion of the passing vehicle. Although none of the sensors can be fully activated at any moment, it is guaranteed that a sufficient number of sensors are still being collected and transmitted. A data, the monitoring mode formed by the number of sensors, the information gathering of the second data satisfying the preset condition in the first data makes the monitoring result of the road bridge state reliable, and is not affected by an individual or a certain area. The working state of the sensor (such as sleep Or broken) the impact. Of course, at night, the sensor can be powered by a general cable, such as a street light.

[0070] In the embodiment of the present invention, the two power supply modes can reduce the dependence on the wired power supply mode to a certain extent, and the "shift mode" working mode of the solar power supply sensor can extend the service life of the sensor to a certain extent. Monitor costs.
