Description

Technical Field

[0001] The invention belongs to the field of industrial Internet of Things and discloses a sewage treatment abnormality monitoring system. Background Art

[0002] As my country's environmental protection continues to deepen, urban sewage treatment plants are becoming more unmanned and automated. Sewage treatment plants often operate 24 hours a day. While sewage treatment is automated, it is often accompanied by equipment failures due to equipment aging, as well as extreme weather causing a surge in server-side processing data, resulting in system crashes, which leads to reduced sewage treatment efficiency, poor sewage treatment results, or even failure to meet standards.

[0003] Therefore, the current sewage monitoring mainly has the following problems: (1) Sensors, coarse screens, inlet and outlet valves and other equipment that are in direct contact with sewage may fail or malfunction due to the impact of large impurities in the sewage or long-term corrosion by sewage. In order to prevent this situation, personnel are often required to check the equipment every day. However, sewage treatment is carried out 24 hours a day, and it is possible that no one will notice abnormalities in sewage treatment.

[0004] (2) Routine sewage treatment: Stable business requires less data processing and network bandwidth on the server side. However, due to extreme weather, the amount of sewage inflow increases sharply, or industrial pollution leakage causes the abnormal values ​​of the inflowing sewage to deviate seriously from the normal. Therefore, the types of sampling devices increase greatly, the sampling frequency increases significantly, the amount of sampled data uploaded is large, and the data is frequently adjusted, which makes the data throughput far exceed the normal data throughput of the server, which can easily cause the server to crash. Summary of the invention

[0005] In view of the deficiencies of the prior art, the present invention provides a sewage treatment abnormality supervision system, comprising a sewage pool collection module, a sewage pool monitoring module, a network transmission device and a monitoring service end module, wherein the sewage pool collection module and the sewage pool monitoring module are electrically connected to the network transmission device, and the network transmission device is electrically connected to the monitoring service end module; the monitoring service end module comprises a master service end and a slave service end, wherein the master service end comprises a master server and a master database, and the slave service end comprises a slave server and a slave database; the sewage pool collection module comprises a COD collection device, a flow measurement device and a turbidity measurement device, and comprises: When the data transmitted by the sewage pool collection module received by the network transmission device exceeds the data flow limit frequency, and / or the amount of data received by the network transmission device exceeds the data flow limit value, the network transmission device will switch a certain amount of traffic transmitted to the master server to the slave server; if the master server is abnormal, the network transmission device will switch all traffic of the master server to the slave server; The sewage pool monitoring module transmits the collected sewage pool image data to the monitoring server module, and the monitoring server module performs image recognition to obtain the detection target; the monitoring server module processes the detection target to obtain an identification value; when the identification value exceeds the warning threshold and the transmission data frequency of the sewage pool collection module received by the network transmission device is lower than the collection failure frequency, the monitoring server module will prompt that the sewage pool collection module has a failure.

[0006] Preferably, the main server receives data transmitted by the sewage pool collection module exceeding the data flow limit frequency, including any of the following situations: 1) When the COD collection device detects highly polluting substances and collects sewage data in real time at a frequency of seconds, the COD collection device opening rate reaches more than 70%; the highly polluting substances include organic matter concentration exceeding 500 mg / L, and / or ammonia nitrogen concentration exceeding 50 mg / L, and / or phosphorus concentration exceeding 1 mg / L, and / or mercury concentration exceeding 0.01 mg / L; 2) At the inlet and outlet of the sewage pool, the water flow rate exceeds 200m³ / h, and the flow measurement device collects data at a frequency of seconds; 3) When the turbidity of the sewage pool exceeds 200 NTU, the turbidity measuring device collects data at a frequency of seconds, and the opening rate of the turbidity measuring device reaches more than 70%.

[0007] Preferably, the data flow limit value is 70-90% of the data volume processed by the main server CPU at full load per second; the certain flow rate is 20-40% of the data volume processed by the main server CPU at full load per second.

[0008] Preferably, the network transmission device switches a certain amount of traffic transmitted to the master server to the slave server, including: 1) The network transmission device converts the data of a certain flow rate collected by the sewage pool collection module and the sewage pool monitoring module into raw data and transmits it to the slave server; 2) The slave server processes the received raw data in one transaction, forms transaction data, and transmits it to the slave database; 3) After a transaction ends, the slave database synchronizes the transaction data to the master database.

[0009] Preferably, the transaction refers to a series of operations in which the monitoring service-end module processes the data generated by one activity of the sewage pool collection module to generate one or more batches of data; one activity of the sewage pool collection module is that the COD collection device and / or the flow measurement device and / or the turbidity measurement device collects data multiple times in succession at a specific collection frequency in a time period to obtain sewage indicators according to the characteristics of the sewage pool collection module; the one time period is 3-10 minutes; the specific collection frequency includes a COD collection device collection frequency of 1-10s / time, a flow measurement device collection frequency of 1-10s / time, and a turbidity measurement device collection frequency of 1-5s / time.

[0010] Preferably, the abnormality on the main server includes network interruption between the main server and the network transmission device, and / or the response time of the main server server exceeds the response time threshold, and / or the number of error responses from the main server exceeds the error response threshold; the response time threshold is 3-5s; the error response threshold is 1-5% of the error response requests to the total number of requests.

[0011] Preferably, the detection targets include sewage water level and block pollutants; the identification values ​​include sewage water level rising rate and block pollutant area ratio; The monitoring server module processes the detection target to obtain an identification value, including: The sewage water level is compared with the previous sewage water level to obtain the water level difference, and then the sewage water level rising rate is calculated based on the time difference generated by the sewage water level image; Calculate the area ratio of block pollutants in the sewage pool image to obtain the area proportion of block pollutants.

[0012] Preferably, when the identification value exceeds the warning threshold and the transmission data frequency of the sewage pool collection module received by the network transmission device is lower than the collection failure frequency, the monitoring service end module will prompt that the sewage pool collection module has a failure, including: The monitoring service module detects that the sewage water level rise rate exceeds the sewage flow rate warning threshold, and the water flow collection frequency transmitted by the flow measurement device is lower than the water flow collection failure frequency, and the monitoring service module will prompt that the flow measurement device has a failure; the sewage flow rate warning threshold is 5-10cm / h; the water flow collection failure frequency is 3-5s; When the monitoring service module detects that the area ratio of block pollutants exceeds the block warning threshold, and the turbidity collection frequency transmitted by the turbidity measuring device is lower than the turbidity collection failure frequency, the monitoring service module will prompt that the turbidity measuring device has a failure; the block warning threshold is 10-20%; the turbidity collection failure frequency is 1-3min / time. The present invention has the following advantages: (1) The present invention uses image recognition technology to monitor the water level of each treatment pool to determine whether the inlet and outlet valves of each treatment pool are abnormal; monitor the distribution and quantity of floating objects such as sedimentation tanks and reaction tanks to determine whether the mud-water separation effect and mixing and flocculation effect are abnormal; at the same time, compare the data collected in the abnormal area to determine whether the coarse or fine grid of the sedimentation tank is abnormal, and whether the dosing device of the reaction tank is abnormal. Because sewage treatment is a heavy treatment, there is a certain buffer time between the occurrence of a fault and the serious consequences. Therefore, the interval time requirement for monitoring image shooting is not high, the amount of data calculation on the server is not large, and the cost is low.

[0013] (2) In the daily sewage treatment of the present invention, the master server controls the sewage treatment pool and processes its various data, and the slave server mainly displays the monitoring data to the management personnel; in the event of a data surge or a failure of the master server, the master server switches a small part of the traffic to the slave server to reduce the pressure on the master server; similarly, when the slave server fails, the traffic from the slave server is switched to the master server, and the master and slave servers are mutually disaster-free, thus solving the disaster recovery backup of the sewage treatment process.

DETAILED DESCRIPTION Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those in the technical field of this application. The meanings generally understood by technicians are the same; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application; the terms "including" and "having" in the specification and claims of the present application and the above-mentioned figure descriptions and any variations thereof are intended to cover non-exclusive inclusions.

[0018] A sewage treatment abnormality monitoring system, such as Figure 1 As shown, it includes a sewage pool collection module, a sewage pool monitoring module, a network transmission device and a monitoring service end module, wherein the sewage pool collection module, the sewage pool monitoring module and the network transmission device are electrically connected, and the network transmission device and the monitoring service end module are electrically connected; Figure 2 As shown, the monitoring service end module includes a master service end and a slave service end, the master service end includes a master server and a master database, and the slave service end includes a slave server and a slave database; the sewage pool collection module includes a COD collection device, a flow measurement device and a turbidity measurement device, including: When the data transmitted by the sewage pool collection module received by the network transmission device exceeds the data flow limit frequency, and / or the amount of data received by the network transmission device exceeds the data flow limit value, the network transmission device will switch a certain amount of traffic transmitted to the master server to the slave server; if the master server is abnormal, the network transmission device will switch all traffic of the master server to the slave server; The sewage pool monitoring module transmits the collected sewage pool image data to the monitoring server module, and the monitoring server module performs image recognition to obtain the detection target; the monitoring server module processes the detection target to obtain an identification value; when the identification value exceeds the warning threshold and the transmission data frequency of the sewage pool collection module received by the network transmission device is lower than the collection failure frequency, the monitoring server module will prompt that the sewage pool collection module has a failure.

[0019] Preferably, the main server receives data transmitted by the sewage pool collection module exceeding the data flow limit frequency, including any of the following situations: 1) When the COD collection device detects highly polluting substances and collects sewage data in real time at a frequency of seconds, the COD collection device opening rate reaches more than 70%; the highly polluting substances include organic matter concentration exceeding 500 mg / L, and / or ammonia nitrogen concentration exceeding 50 mg / L, and / or phosphorus concentration exceeding 1 mg / L, and / or mercury concentration exceeding 0.01 mg / L; 2) At the inlet and outlet of the sewage pool, the water flow rate exceeds 200m³ / h, and the flow measurement device collects data at a frequency of seconds; 3) When the turbidity of the sewage pool exceeds 200 NTU, the turbidity measuring device collects data at a frequency of seconds, and the opening rate of the turbidity measuring device reaches more than 70%.

[0020] Since the COD collection devices and turbidity measuring devices are evenly distributed in the horizontal and vertical planes of the sewage pool, only some of the collection devices will be turned on when the sewage treatment volume is not large; if the flow switching is determined only by transmitting data over the network, the initial data transmission flow may not reach the critical point, but each collection device is already operating at full capacity, and the sudden instantaneous flow breaks through the flow bottom line of normal operation of the server.

[0021] Preferably, the data flow limit value is 70-90% of the data volume processed by the main server CPU at full load per second; the certain flow rate is 20-40% of the data volume processed by the main server CPU at full load per second.

[0022] Preferably, the network transmission device switches a certain amount of traffic transmitted to the master server to the slave server, such as Figure 3 As shown, including: 1) The network transmission device converts the data of a certain flow rate collected by the sewage pool collection module and the sewage pool monitoring module into raw data and transmits it to the slave server; 2) The slave server processes the received raw data in one transaction, forms transaction data, and transmits it to the slave database; 3) After a transaction ends, the slave database synchronizes the transaction data to the master database.

[0023] Preferably, the transaction refers to a series of operations in which the monitoring service-end module processes the data generated by one activity of the sewage pool collection module to generate one or more batches of data; one activity of the sewage pool collection module is that the COD collection device and / or the flow measurement device and / or the turbidity measurement device collects data multiple times in succession at a specific collection frequency in a time period to obtain sewage indicators according to the characteristics of the sewage pool collection module; the one time period is 3-10 minutes; the specific collection frequency includes a COD collection device collection frequency of 1-10s / time, a flow measurement device collection frequency of 1-10s / time, and a turbidity measurement device collection frequency of 1-5s / time.
