[0062] Embodiment one

[0063] Please refer to Figure 1 , Figure 1 is a flowchart of a monitoring method of a desulfurization absorption tower system provided by the embodiments of the present application, and the method comprises the following steps:

[0064] S100, acquiring the values of a plurality of monitoring devices of the desulfurization absorption tower system; wherein the data types of the values of the monitoring devices include PH value, temperature, pressure and flow rate;

[0065] The desulfurization absorption tower system comprises a plurality of sub-devices, and each sub-device is provided with a plurality of monitoring devices.

[0066]

[0067] S200, evaluating the values of the monitoring devices based on the emergency levels of the data types of the values of the monitoring devices and the operating states of the monitoring devices, to obtain the scores of the values of the monitoring devices;

[0068] In an embodiment, step S200 specifically comprises:

[0069] Specifically, the operating state comprises an online state and an offline state.

[0070] For the values of the monitoring devices:

[0071] S210, when the operating state of the monitoring device is the online state, determining the score of the value of the monitoring device based on the emergency level of the data type of the value of the monitoring device;

[0072] In an embodiment, when the triggering operation of the user for the selection display control is monitored, the score of the value of the monitoring device is determined based on the emergency level of the data type of the value of the monitoring device.

[0073] In the embodiment, the initiative operation of the user is incorporated into the scoring process, thereby improving the interactivity, instantaneity, context awareness, user engagement, pertinence, dynamic adjustment capability and prevention of the system.

[0074] Specifically, the emergency levels of the data type of the numerical value of the monitoring device include: a first emergency level, a second emergency level and a third emergency level.

[0075] The following will be described in detail how to determine the score of the numerical value of the monitoring device under each emergency level:

[0076] The first emergency level:

[0077] For the numerical value of each monitoring device:

[0078] S211, in the case where the emergency level of the data type of the numerical value of the monitoring device is the first emergency level, if the numerical value of the monitoring device is greater than the preset optimal lower limit value and less than the preset optimal upper limit value, it is determined that the score of the numerical value of the monitoring device is a first preset score;

[0079] S212, in the case where the emergency level of the data type of the numerical value of the monitoring device is the first emergency level, if the numerical value of the monitoring device is greater than the preset optimal upper limit value and less than the preset maximum allowable value, or the numerical value of the monitoring device is greater than the preset minimum allowable value and less than the preset optimal lower limit value, it is determined that the score of the numerical value of the monitoring device is a second preset score;

[0080] S213, in the case where the emergency level of the data type of the numerical value of the monitoring device is the first emergency level, if the numerical value of the monitoring device is greater than the preset maximum limit value or less than the preset minimum limit value, it is determined that the score of the numerical value of the monitoring device is a third preset score.

[0081] The second emergency level:

[0082] For the numerical value of each monitoring device:

[0083] S211', in the case where the emergency level of the data type of the numerical value of the monitoring device is the second emergency level, if the numerical value of the monitoring device is greater than the preset optimal lower limit value and less than the preset optimal upper limit value, it is determined that the score of the numerical value of the monitoring device is a second preset score;

[0084] S212', in the case where the emergency level of the data type of the numerical value of the monitoring device is the second emergency level, if the numerical value of the monitoring device is greater than the preset optimal upper limit value and less than the preset maximum allowable value, or the numerical value of the monitoring device is greater than the preset minimum allowable value and less than the preset optimal lower limit value, it is determined that the score of the numerical value of the monitoring device is a third preset score;

[0085] S213', in the case that the emergency level of the data type of the value of the monitoring device is the second emergency level, if the value of the monitoring device is greater than the preset maximum limit value or less than the preset minimum limit value, it is determined that the score of the value of the monitoring device is the fourth preset score.

[0086] The third emergency level:

[0087] For the value of each monitoring device:

[0088] S211'', in the case that the emergency level of the data type of the value of the monitoring device is the third emergency level, if the value of the monitoring device is greater than the preset optimal lower limit value and less than the preset optimal upper limit value, it is determined that the score of the value of the monitoring device is the third preset score;

[0089] S212'', in the case that the emergency level of the data type of the value of the monitoring device is the third emergency level, if the value of the monitoring device is greater than the preset optimal upper limit value and less than the preset maximum allowable value, or the value of the monitoring device is greater than the preset minimum allowable value and less than the preset optimal lower limit value, it is determined that the score of the value of the monitoring device is the fourth preset score;

[0090] S213'', in the case that the emergency level of the data type of the value of the monitoring device is the third emergency level, if the value of the monitoring device is greater than the preset maximum limit value or less than the preset minimum limit value, it is determined that the score of the value of the monitoring device is the fifth preset score.

[0091] It should be noted that the preset maximum limit value > the preset maximum allowable value > the preset optimal upper limit value > the preset optimal lower limit value > the preset minimum allowable value > the preset minimum limit value;

[0092] It should be noted that the first preset score > the second preset score > the third preset score > the fourth preset score > the fifth preset score.

[0093] S220, when the running state of the monitoring device is the offline state, it is determined that the score of the value of the monitoring device is the first preset score.

[0094] Specifically, when the value of the monitoring device participates in scoring, some monitoring devices are in shutdown state, and the running signal of the monitoring device is not required to be collected for real-time parameter evaluation for a short time. The scoring of the device is associated with the scoring of the device. When the monitoring device is shutdown, the score of the measuring point is set to 100. That is, a channel selector is added, when the running signal is 1, the output value of the scoring module is selected, when the running signal is 0, the score 100 is output, or some parameters need to be temporarily withdrawn from participating in scoring, and also set to full score 100 output, so there will be no low score alarm prompt.

[0095] Regarding step S200, the following is an example:

[0096] Taking the PH value of the slurry in the slurry pool as an example, the emergency level of the PH value of the slurry is level one, it is assumed that the PH value of the slurry is 4.5, the preset maximum limit value of the PH of the slurry is 7, the preset minimum limit value of the PH of the slurry is 4, the preset maximum allowable value of the PH of the slurry is 6, the preset minimum allowable value of the PH of the slurry is 4, the preset optimal upper limit value of the PH of the slurry is 6, and the preset optimal lower limit value of the PH of the slurry is 3.

[0097] Firstly, the running state of the monitoring device corresponding to the PH of the slurry is judged.

[0098] If it is an offline state, since it is in the offline state, it is indicated that the parameter needs to be temporarily exited from scoring, so the score of the PH of the slurry is marked as 100 points.

[0099] If it is an online state, the emergency level of the PH value of the slurry needs to be judged, it is known that the emergency level of the PH value of the slurry is level one, and the preset optimal lower limit value of the PH of the slurry (3) < the PH value of the slurry (4.5) < the preset maximum allowable value of the PH of the slurry (6), so according to the rules, the score of the PH value of the slurry is 100 points.

[0100] The judgment of the PH value of the slurry under other emergency levels can be deduced in the same way, which will not be described here.

[0101] S300, the average value of the scores of the values of the monitoring devices is calculated, the scores of the sub-devices of the desulfurization absorption tower system are obtained, and the average value of the scores of the sub-devices of the desulfurization absorption tower system is calculated to obtain the score of the desulfurization absorption tower system;

[0102] S400, the scores of the values of the monitoring devices, the scores of the sub-devices of the desulfurization absorption tower system, and the score of the desulfurization absorption tower system are transmitted to the display control system, so that the display control system displays the scores of the values of the monitoring devices, the scores of the sub-devices of the desulfurization absorption tower system, and the score of the desulfurization absorption tower system in layers.

[0103] In an embodiment, the display control system can be a DCS system. DCS (Distributed Control System) is a new generation of instrument control system based on microprocessors. It adopts the design principle of decentralized control function and centralized display operation, combines computer technology, control technology, communication technology and graphic display technology. DCS system is widely used in power, metallurgy, petrochemical and other industries, and gradually becomes the mainstream system of industrial process control

[0104] In an embodiment, when the score of the value of the monitoring device, the score of the sub-device of the desulfurization absorption tower system, and the score of the desulfurization absorption tower system are 0-60 points, a red warning light is displayed on the DCS system.

[0105] In an embodiment, when the score of the numerical value of the monitoring device, the score of each sub-device of the desulfurization absorption tower system, and the score of the desulfurization absorption tower system are 60-80 points, a yellow warning light is displayed on the DCS system.

[0106] In an embodiment, when the score of the numerical value of the monitoring device, the score of each sub-device of the desulfurization absorption tower system, and the score of the desulfurization absorption tower system are 80-100 points, a green warning light is displayed on the DCS system.

[0107] Specifically, as shown in Figure 2 , the DCS system displays the running status of multiple sub-devices of the desulfurization absorption tower system on the display interface, and then clicks any one sub-device, as shown in Figure 3 , the numerical values of multiple monitoring devices under the sub-device are displayed. Figure 3

[0108] In an embodiment, the desulfurization absorption tower system monitoring method is applied to a desulfurization absorption tower data processing system, and the desulfurization absorption tower data processing system and the DCS system realize data intercommunication through a table data interface and a MODBUS protocol.

[0109] In this embodiment, through the realization of data intercommunication of TDI (table data interface) and MODBUS protocol between the computing platform and the desulfurization system, efficient and reliable data exchange and communication between the two systems are ensured to realize real-time monitoring, data processing and analysis, and remote control of the operation and maintenance of the desulfurization system.

[0110] Advantages of the present application:

[0111] (1) Real-time monitoring and early warning: the numerical value of the monitoring device is obtained in real time, the running state of each sub-device is mastered in time, abnormal conditions are found and early warning is made quickly.

[0112] (2) Fault diagnosis and troubleshooting: by evaluating the numerical value of the monitoring device, the operator can quickly locate the problem point, and the efficiency of fault diagnosis and troubleshooting is improved.

[0113] (3) Data integration and sharing: the score data is transmitted to the DCS system, realizing data integration and sharing, and facilitating unified management and decision support.

[0114] (4) Visual display: the hierarchical display function of the DCS system makes the monitoring data more intuitive, and improves the work efficiency of the operator.
