Problems solved by technology

[0006] When relying on the operator to find out the cause of the failure, the impact of the failure, etc., there is a problem that the burden on the operator will be increased, and it will often become a source of human error. main reason
In addition, when installing a dedicated diagnostic unit, there is a problem that the system is complicated by a large change of the target device
[0007]Because of the above situation, there is a demand for correct plant equipment that can prevent the reliability of the plant from deteriorating due to the aging of the equipment and can accurately grasp the state of the plant. Automatic Monitoring and Diagnosis
For this reason, as described above, the increase in the number of devices due to the wide area and the increase in the amount of information due to the high functionality of the devices make the system more complicated, and it is necessary to ask the operator Provide more understandable monitoring system information

no. 1 Embodiment approach 》

[0018] [constitute]

[0019] FIG. 1 is a block diagram showing a comprehensive monitoring and diagnosis system to which the first embodiment of the comprehensive monitoring and diagnosis device of the present invention is applied.

[0020] The comprehensive monitoring and diagnosis system 1a shown in this figure includes a rainfall radar processing device 4 and a comprehensive monitoring and diagnosis device 8a. The rainfall radar processing device 4 reads the rainfall information output from each rainfall radar 2 installed in each place and sends it to the network 3. Above, the comprehensive monitoring and diagnosis device 8a reads the rainfall information output from the upper rain gauges 5 installed in various places, and the treatment value from the sewage treatment field 6 as the monitoring object, and makes the pump wells installed in the sewage treatment field 6 The water level of 7 is kept below a certain level, and the quality and operation status of each equipment co...

[0047] [constitute]

[0048] Fig. 3 is a block diagram showing a second embodiment of the comprehensive monitoring and diagnosis system of the present invention. In addition, in this figure, the same code|symbol is attached|subjected to the part corresponding to each part of FIG.

[0049] The difference between the comprehensive monitoring and diagnosis system 1b shown in this figure and the comprehensive monitoring and diagnosis system 1a shown in FIG. Central monitoring device 32 is set in the center), and the diagnosis result obtained in the comprehensive monitoring and diagnosis device 8b is transmitted to the central monitoring device 32 in the form of diagnostic medical records, and the operator in the central monitoring room holds a portable terminal device 33 and notifies the equipment Operators outside the premises (airport).

[0050] The data relay unit 31 is equipped with a diagnostic result processing process 34. As shown in FIG. 4, it reads the plant diagnostic ...

other Embodiment approach

[0108] In addition, as other methods for solving the above-mentioned optimal control problem, the application of the divergence limitation method, the genetic calculation method, and the like can be considered. The advantage of the bifurcation restriction method is that it checks part of the solution space collectively and checks in advance whether or not there are candidate solutions in this space, thereby eliminating unnecessary search procedures in advance. Although it takes time in calculation, it can find Best answer. In addition, the genetic algorithm cannot retrieve the optimal answer, but can only retrieve the quasi-optimal solution, and its advantages are that it is difficult to fall into a local minimum solution and can expect fast operation.

[0109] In addition, the above-mentioned method assumes that only the current information of the above-ground rain gauge 5 is used to predict the inflow of the pump field, the inflow of the pump well, and the water level of the...

Abstract

The invention provides a synthesized monitoring and diagnosing device (8a) which controls respective rain pumps (15) and respective discharging valves (16) according to rain information outputted from a precipitation radar processing device (4), precipitation information outputted from pluviometers (5) of respective places, and processing information outputted form an afflux trench nilometer (9) provided at a drain processing site (6), a well nilometer (10), an afflux gate (11), etc., makes a water level of a well (7) be held below a predetermined water level, and diagnoses a processing valueand operation content and the like of the drain processing site (6), indicates a diagnosed result to operators.

Description

technical field [0001] The present invention relates to a comprehensive monitoring and diagnosing system for monitoring sewer equipment, etc., and in particular to a comprehensive monitoring and diagnosing device for diagnosing sewer equipment, finding out the cause of a failure, and displaying the impact of the failure. Background technique [0002] The monitoring system was first applied to the complete set of water and sewage equipment, and the target of use is the complete set of equipment composed of many devices. In recent years, the amount of information handled in the monitoring system has been increasing along with the high functionality of the plant. In addition, the number of devices is increasing due to wide-area management of plants. [0003] On the other hand, there is a demand for stable service to plant facilities such as water purification plants, sewage treatment plants, and power plants that exist in lifelines, and these plant plants must have high reliab...
