Description

TECHNICAL FIELD

[0001] The application relates to the technical field of monitoring alarm, in particular to a construction site all-weather alarm system. BACKGROUND

[0002] The construction site environment is complex and has many safety hazards. Although the traditional safety management mode meets the all-weather and all-directional monitoring requirements of the construction site, starting all monitoring devices all the time brings a large energy consumption burden to the operation of the construction site, which is not conducive to the continuous operation of the monitoring system. Therefore, the application provides a construction site all-weather alarm system.

[0003] The prior art such as the invention patent for a construction site area dust monitoring method and system with the announcement number CN115508258A discloses a construction site area dust monitoring method and system, which comprises the following steps: constructing a three-dimensional monitoring model of the construction site area; obtaining first dust monitoring data of a plurality of fixed-point monitoring terminals; mapping the first dust monitoring data to the three-dimensional monitoring model based on the installation positions of the fixed-point monitoring terminals; obtaining second dust monitoring data and positioning data of a plurality of mobile monitoring terminals; mapping the second dust monitoring data to the three-dimensional monitoring model based on the positioning data; and determining dust data of each monitoring point in the construction site area based on the second dust monitoring data, the first dust monitoring data and the three-dimensional monitoring model.

[0004] For the above-mentioned scheme, the following technical problems exist: 1. The current technology mainly monitors the dust data of each monitoring point of the construction site through a monitoring model. However, when the construction site area is in a non-working time, the construction site area is in a closed state, and at this time, no dust data will be generated. It is meaningless to monitor the dust data during this period of time, and a large amount of cost will be consumed due to continuous monitoring.

[0005] 2. In addition to dust, the temperature, humidity, noise, smoke, fire and gas in the construction site area also need to be monitored. The current technology only monitors the dust data in the construction site area. The activities in the construction site area are different at different time periods, so the monitoring content required by the construction site area is also different at different time periods. The current technology ignores this aspect, resulting in the lack of comprehensiveness and perfection of the current monitoring technology. SUMMARY

[0009] The monitoring content analysis module is configured to analyze the monitoring content of each key monitoring time period and the monitoring content of each non-key monitoring time period of the target region.

[0016] In order to more clearly illustrate the technical solutions in the embodiments of the present application or the prior art, the drawings needed to be used in the embodiments or prior art description will be briefly introduced. Obviously, the drawings in the following description are only some embodiments of the present application, and those skilled in the art can obtain other drawings according to these drawings without creative labor.

[0017] Figure 1 The system structure connection diagram of the present application is shown. DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0019] Referring to Figure 1 As shown in the figure, the present application provides a construction site all-weather alarm system, which comprises a region analysis module, a monitoring content analysis module, a monitoring device analysis module, a monitoring device control module and an alarm module.

[0020] The region analysis module is used to obtain the site scheduling plan and historical monitoring information from the data center, and then analyze the target area according to the site scheduling plan and historical monitoring information to obtain each key monitoring time period and each non-key monitoring time period of the target area.

[0021] In one specific example, the analysis of the target area according to the construction site scheduling plan and the historical monitoring information obtains the key monitoring time periods and the non-key monitoring time periods of the target area, and the specific process is as follows: based on the construction site scheduling plan, the working time periods, the non-working time periods and the shift handover time periods corresponding to the target area are obtained, and then the average number of people and the volume of the target area in the non-working time periods and the shift handover time periods of the target area are obtained from the historical monitoring information, so as to analyze and obtain the personnel density of the target area in the non-working time periods and the shift handover time periods.

[0022] It should be noted that the volume of the target area is divided by the average number of people to obtain the personnel density of the target area.

[0023] Based on the historical alarm information, the number of historical alarms of the target area in the non-working time periods and the shift handover time periods is obtained.

[0024] For the non-working time periods and the shift handover time periods, when the personnel density of the target area is less than the set personnel density threshold and the number of alarms is less than the set alarm number threshold, it indicates that the target area does not need to be monitored, otherwise it indicates that the target area needs to be monitored, and for the working time periods, each working time period is recorded as a key monitoring time period, and thus the key monitoring time periods and the non-key monitoring time periods of the target area are obtained.

[0025] The monitoring content analysis module is used to analyze the monitoring content of the key monitoring time periods and the non-key monitoring time periods of the target area.

[0026] In one specific example, the analysis of the monitoring content of the key monitoring time periods and the non-key monitoring time periods of the target area is as follows: for the key monitoring time periods, first, the historical alarm keywords of the target area are extracted from the historical alarm records to construct an alarm keyword set of the target key monitoring time period; then, based on the construction site construction plan, the scene keywords and the work keywords of the target area are obtained to construct a scene keyword set and a work keyword set of the key monitoring time period, and finally, based on the alarm keywords, the scene description keywords and the work description keywords of the target area, a demand monitoring content keyword set of the target area in the key monitoring time periods is obtained.

[0027] It should be noted that, for example, in an installation engineering construction area, the alarm was triggered due to abnormal gas exceeding the standard, and "abnormal gas", "leakage" and "exceeding the standard" are alarm keywords, "electricity", "drainage", "dust" and "abnormal gas" are scene keywords, and "construction personnel" and "protection" are work keywords, wherein the alarm keywords, the scene keywords and the work keywords are allowed to overlap.

[0028] For each non-key monitoring time period, the set of scene description keywords of the target area is taken as the set of demand monitoring content keywords of the target area in each non-key monitoring time period.

[0029] The monitoring device analysis module is configured to analyze the monitoring content of each monitoring device, and match the monitoring content of each monitoring device with the demand monitoring content of the target area in each time period, to obtain the monitoring device of the target area in each time period.

[0030] It should be noted that the time periods include key monitoring time periods and non-key monitoring time periods.

[0031] In one specific example, the analysis of the monitoring content of each monitoring device is specifically as follows: the monitoring content keywords corresponding to each monitoring device are obtained from the product specification of each monitoring device, and then the set of monitoring content keywords of each monitoring device is constructed, and the use scene keywords corresponding to each monitoring device are obtained from the product specification of each monitoring device, and then the set of use scene keywords of each monitoring device is constructed, and the target monitoring keyword set of each monitoring device is obtained by comprehensively analyzing the set of monitoring content keywords and the set of use scene keywords of each monitoring device.

[0032] In one specific example, the matching of the monitoring content of each monitoring device with the demand monitoring content of the target area in each time period, to obtain the monitoring device of the target area in each time period, is specifically as follows: first, the set of demand monitoring content keywords of the target area in each time period is matched with the target monitoring keyword set of each monitoring device, and then the candidate monitoring device of the target area in each time period is obtained.

[0033] The monitoring content and monitoring cost of each candidate monitoring device are analyzed to obtain the best monitoring device of the target area in each time period.

[0034] In one specific example, the matching of the set of demand monitoring content keywords of the target area in each time period with the target monitoring keyword set of each monitoring device is specifically as follows: for non-key monitoring time periods, the set of demand monitoring content keywords of the target area in non-key monitoring time periods is matched with the target monitoring keyword set of each monitoring device, and if the set of demand monitoring content keywords of the target area in non-key monitoring time periods is a subset of the target monitoring keyword set of a certain monitoring device, then the certain monitoring device is recorded as a candidate monitoring device of the target area in non-key monitoring time periods, and accordingly, each candidate monitoring device of the target area in non-key monitoring time periods is obtained.

[0035] It should be noted that since the monitoring content of non-key monitoring time periods is relatively simple, a single monitoring device can be used to monitor the target area in non-key monitoring time periods.

[0036] For the key monitoring time period, each demand monitoring content keyword of the target area in the key monitoring time period is extracted from the demand monitoring content keyword set, and each demand content keyword is searched in the target monitoring keyword set of each monitoring device. The camera device corresponding to the target monitoring keyword set containing any demand monitoring content keyword is recorded as the candidate monitoring device of the key monitoring time period, and each candidate monitoring device of the target area in the key monitoring time period is obtained. Each monitoring device corresponding to each demand monitoring content keyword is combined to obtain each candidate monitoring device combination, wherein the demand monitoring content keyword set of the target area in the key monitoring time period is a subset of the target monitoring keyword set of any candidate monitoring device combination.

[0037] In one specific example, the monitoring content and monitoring cost of each candidate monitoring device are analyzed to obtain each optimal monitoring device of the target area in each time period, and the specific process is as follows: for each candidate monitoring device of the target area in the non-key monitoring time period, the running energy consumption cost corresponding to each candidate monitoring device is obtained from the product specification of each candidate monitoring device, and the candidate monitoring device with the lowest running energy consumption cost is recorded as the optimal monitoring device of the target area in the non-key monitoring time period.

[0038] For each candidate monitoring device combination of the target area in the key monitoring time period, the running energy consumption cost corresponding to each candidate monitoring device is obtained from the product specification of each candidate monitoring device, and the combination running energy consumption cost of each candidate monitoring device combination is obtained. The candidate monitoring device combination with the lowest combination running energy consumption cost is recorded as the optimal monitoring device combination of the target area in the key monitoring time period.

[0039] The monitoring device control module is used to control the monitoring frequency of each monitoring device of the target area in each time period, and then sends an alarm signal to the alarm module and receives a return signal from the alarm module, and then controls each monitoring device of the target area.

[0040] In one specific example, the monitoring frequency of each monitoring device of the target area in each time period is controlled, and the specific process is as follows: in each non-key monitoring time period, the monitoring device corresponding to the non-key monitoring time period is started, and the alarm record of the target area in each non-key time period is obtained based on the historical alarm information. If there is no alarm record of the target area in a certain non-key monitoring time period, the monitoring device of the certain non-key monitoring time period is controlled to collect the monitoring information of the target area at the lowest monitoring frequency. If there is an alarm record of the target area in a certain non-key monitoring time period, the monitoring frequency of the target area at each alarm time is obtained, and the monitoring frequency of the current non-key monitoring time period of the target area is controlled based on the highest monitoring frequency of the target area at each alarm time.

[0041] In each key monitoring time period, the best monitoring device combination corresponding to the key monitoring time period is started, and the alarm record and alarm content of the key monitoring time period are inquired based on the historical monitoring information. If the target area has no alarm record in a key monitoring time period, each monitoring device in the best monitoring device combination is controlled to collect monitoring information at the lowest monitoring frequency. If the target area has an alarm record in a key monitoring time period, the alarm content corresponding to the alarm record is obtained, and the monitoring device corresponding to the alarm content is adjusted to the highest monitoring frequency, and the monitoring frequency of the remaining monitoring devices is adjusted to the middle monitoring frequency.

[0042] It should be noted that the lowest monitoring frequency, the highest monitoring frequency and the middle monitoring frequency are obtained by inquiring the product manual of the relevant monitoring device.

[0043] In a specific example, the alarm module is sent an alarm signal, and a return signal from the alarm module is received, and the specific process is as follows: the best monitoring device in each non-key monitoring time period sends a first feedback signal to the alarm module. The alarm module determines whether the target area is abnormal based on the received first feedback signal. If the target area is normal, a second feedback signal is returned to the monitoring device control module. If the target area is abnormal, the alarm module alarms and returns a third feedback signal to the monitoring device control module.

[0044] The best monitoring device combination in each key monitoring time period sends a first feedback signal to the alarm module. The alarm module determines whether the target area is abnormal based on the received first feedback signal. If the target area is normal, a second feedback signal is returned to the monitoring device control module. If the target area is abnormal, the alarm module alarms and returns a fourth feedback signal to the monitoring device control module.

[0045] In a specific example, the monitoring device control module receives the second feedback signal and continues to monitor the target area at the original monitoring frequency.

[0046] The monitoring device control module receives the third feedback signal, starts each monitoring device in the target area, and monitors the target area based on the highest monitoring frequency of each monitoring device.

[0047] The monitoring device control module receives the fourth feedback signal, adjusts the monitoring frequency of each monitoring device in the best monitoring device combination to the highest level, and monitors the target area accordingly.

[0048] Alarm module: used for receiving signals from the monitoring device control module, returning signals and alarming.

[0049] The application provides a construction site all-weather alarm system, which analyzes each historical monitoring information of each time period of a target area, obtains each key monitoring time period and each non-key monitoring time period of the target area, matches the monitoring content of each key monitoring time period and each non-key monitoring time period with the monitoring content of each monitoring device, respectively obtains each monitoring device of each key monitoring time period and each non-key monitoring time period, selectively uses different monitoring devices in different time periods, thereby reducing the number of simultaneously running monitoring devices, and preferentially using monitoring devices with low energy consumption to monitor, meeting the monitoring content, taking into account the monitoring cost, realizing reasonable distribution of energy, simultaneously reducing unnecessary running time of the monitoring devices, reducing the wear and tear and aging degree of the monitoring devices, and prolonging the service life of the devices.

[0050] The above is only an example and description of the concept of the application, and those skilled in the art can make various modifications or supplements or use similar ways to replace the described specific embodiments, as long as the concept of the application is not deviated or the scope defined by the application is not exceeded, which shall belong to the protection scope of the application.
