The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate embodiments of the invention and, together with the description, serve to explain the invention and not to limit the invention. In the drawings:
fig. 1 is a block diagram of a high-formwork monitoring system disclosed in an embodiment of the present invention.
Fig. 2 is a schematic flow chart of a high formwork detection method disclosed in the embodiment of the present invention.
Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
Example 1
In this embodiment, a high formwork monitoring system is disclosed, as shown in fig. 1, a wireless data acquisition terminal forms a local area network (essentially, a monitoring station) with a wireless audible and visual alarm and sensors, each of which includes a wireless load cell, a wireless displacement cell and a wireless inclinometer to detect and cover numerous parameters such as vertical shaft force, horizontal displacement, formwork settlement and the like through multiple points. The wireless data acquisition terminal further establishes data communication connection with a remote server through a wireless gateway, and is used for executing functions of edge nodes to perform alarm diagnosis on data uploaded by each sensor, for example: and judging whether an alarm is generated or not, if so, judging the alarm grade and the like, wherein when the alarm is judged to exist, related alarm data and alarm diagnosis information are sent to a remote server for the remote server to recheck and/or execute other corresponding linkage processing.
In this embodiment, a preset warning data is stored in the local memory of each sensor (that is, the wireless data acquisition terminal inevitably judges that there is a warning according to normal processing logic and determines the potential safety hazard data of the corresponding warning level), and each warning data is backed up in a database that can be read by a remote server (the warning data corresponding to each type of sensor is different). The data volume of each alarm data can be set reasonably according to the time interval of the adjacent reporting frequency in the subsequent sending, and can be generally lower than half of the data volume collected between the normal reporting frequencies. Preferably, the alarm data of the sensors corresponding to the same detection station are classified and stored in the same data buffer area.
Optionally, the wireless displacement meter of the present embodiment comprises at least three pull wire displacement meters for measuring X-axis, Y-axis and Z-axis displacement, respectively.
In this embodiment, the remote server is configured to set a test time period, generate corresponding test instructions one by one in a polling sequence in the test time period to instruct each sensor to report preset alarm data to the wireless data acquisition terminal in a wrong sequence, and synchronously enter information indicating that the acoustic-optical alarm instructs the acoustic-optical alarm to normally process or ignore an alarm generated by the wireless data acquisition terminal, where when the test user instructs the acoustic-optical alarm to ignore an alarm generated by the wireless data acquisition terminal, the information indicating that the acoustic-optical alarm ignores the alarm generated by the wireless data acquisition terminal carries information of the test time period. If the testing user indicates that the audible and visual alarm normally processes the alarm information generated by the wireless data acquisition terminal, the audible and visual alarm can be omitted from informing the audible and visual alarm of the distribution information of the testing time period.
After receiving the test instruction of the remote server, each sensor sends preset alarm data to the wireless data acquisition terminal in the time interval of the adjacent frequency of the reported real-time monitoring data. Preferably, each sensor is further configured to indicate, in the extension field of the data frame, real-time detection data of the transmitted data, which is reported from a regular interval period, or alarm data pre-stored in the local memory, through a corresponding command indicator, so as to be recognized by the remote server. Preferably, to simplify the processing logic of the system for quick identification by the remote server, each sensor may uniformly use two different commanders to distinguish between different data sources.
The remote server is also used for judging whether the data source of the alarm is real-time detection data reported by the corresponding sensor according to the alarm data reported by the wireless data acquisition terminal and the corresponding alarm diagnosis information in the test time period, if so, terminating the test process and indicating that the test process of the audible and visual alarm is terminated and outputting the alarm immediately; otherwise, whether the wireless data acquisition unit and the corresponding sensor have faults is judged according to the alarm data sent by the wireless data acquisition terminal and the corresponding alarm diagnosis information and the alarm data backed up by the database.
Optionally, when the command symbol of the sensor data source is not indicated in the data frame, as an alternative, the remote server may determine the source of the data by using the timestamp information of the data frame and the frequency period of the real-time monitoring data reported by the corresponding sensor; and/or judging the source of the data according to the data volume of the alarm data. Such modifications are well known to those skilled in the art and will not be described in detail.
Example 2
Corresponding to the above embodiments, the present embodiment discloses a method for monitoring a high formwork, as shown in fig. 2, including at least the following steps:
s1, storing a preset alarm data in a local memory of each sensor, and backing up each alarm data in a database which can be read by a remote server.
And S2, the remote server generates corresponding test instructions one by one in a polling sequence to indicate each sensor to report preset alarm data to the wireless data acquisition terminal in a wrong sequence, synchronously inputs information indicating that the audible and visual alarm is normally processed or ignores the alarm generated by the wireless data acquisition terminal by a test user, and carries the information of the test time period in the information indicating that the audible and visual alarm ignores the alarm generated by the wireless data acquisition terminal when the test user indicates that the audible and visual alarm ignores the alarm generated by the wireless data acquisition terminal. Correspondingly, after receiving the corresponding ignoring instruction, the audible and visual alarm executes corresponding ignoring processing on the alarm information generated by the wireless data acquisition terminal in the corresponding testing time period. In the processing logic of the audible and visual alarm, when resources conflict with instructions, the priority of the instructions issued by the remote server is higher than that of the instructions issued by the wireless data acquisition terminal, and the audible and visual alarm can judge the source of the relevant instructions according to the source address in the data frame.
In the polling process in this step, the test of the current sensor is completed before switching to the test of the next sensor. Alternatively, the ordering in the polling process may be based on the ordering of the IP addresses of the sensors. Because the data transmitted between the sensors has correlation when potential safety hazards appear, when preset alarm data are dispersedly deployed on the corresponding sensors and the test process is processed in a polling manner, the following steps are also performed: in the process of testing the sensor A, normal alarms of other sensors such as B, C, D and E are prevented from being ignored; therefore, the potential safety detection hazard in the test process is ensured by multiple measures.
And S3, after receiving the test instruction of the remote server, each sensor uploads preset alarm data to the wireless data acquisition terminal in a time interval of adjacent reporting frequency of the real-time monitoring data. Therefore, the normal processing time sequence of the sensor for the real-time collected data is not influenced.
S4, in the testing time period, the remote server judges whether the data source of the alarm is real-time detection data reported by a corresponding sensor according to the alarm data reported by the wireless data acquisition terminal and corresponding alarm diagnosis information, if so, the testing process is terminated, the audible and visual alarm testing process is indicated to be terminated, and the alarm is output immediately; otherwise, whether the wireless data acquisition unit and the corresponding sensor have faults is judged according to the alarm data sent by the wireless data acquisition terminal and the corresponding alarm diagnosis information and the alarm data backed up by the database.
In the step, the wireless data acquisition terminal corresponds to a plurality of sensors, so that whether the fault is from the sensor or the wireless data acquisition terminal can be easily distinguished; for example, the wireless data acquisition terminal processes the alarm data of the wireless load meter normally, and when the analyzed alarm data uploaded by the displacement sensor in the test process is inconsistent with the alarm data stored in the database and exceeds a set threshold, the displacement sensor can be judged to have a fault. The wireless data acquisition terminal is judged whether faults exist or not mainly based on whether the alarm diagnosis is consistent with an ideal diagnosis result or not. In the testing process, the wireless data acquisition terminal does not need to judge the source of data uploaded by each sensor so as to maintain the consistency with the normal data processing logic, and the data processing function disorder caused by the testing reason is avoided.
In summary, the high formwork detection system and method disclosed in the above embodiments of the present invention at least have the following beneficial effects:
and in the testing time period, the remote server can judge whether the wireless data acquisition unit and the corresponding sensor have faults or not according to the alarm data sent by the wireless data acquisition terminal and the corresponding alarm diagnosis information and the alarm data backed up by the database. And in the testing process, each sensor sends preset alarm data to the wireless data acquisition terminal in the time interval of adjacent frequencies of the reported real-time monitoring data, and when the alarm data reported by the wireless data acquisition terminal and corresponding alarm diagnosis information are identified and the alarm data are judged to be from the real-time detection data reported according to the normal interval period, the testing process is terminated and the audible and visual alarm is indicated to terminate and output the alarm immediately, so that the normal service of the system detection function is ensured, and the system safety in the testing process is ensured. In addition, in the testing time period, the audible and visual alarm can be indicated to ignore the alarm generated by the wireless data acquisition terminal, and the confusion caused by invalid alarm to field personnel can be effectively avoided.
Therefore, the scheme of the invention carries out comprehensive consideration by combining a plurality of dimensions of the field environment and the system operation, and can evaluate the reliability of the system operation according to the user requirements or at regular intervals, thereby improving the safety of the engineering construction. The method is simple and practical; is worthy of being widely popularized and implemented.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
