Description

Technical Field

[0001] The invention relates to the technical field of rotary fine grid testing, and in particular to a control system and method for rotary fine grid testing. Background Art

[0002] The rotary fine screen is a special water treatment equipment that can continuously and automatically intercept and remove various shapes of debris in the fluid. It can be widely used in urban sewage treatment. The tap water industry and the water inlet of power plants can also be used as the pre-screening equipment in the wastewater treatment process of textile, food processing, papermaking, leather and other industries. It is one of the most advanced solid-liquid screening equipment in my country.

[0003] The rotary fine screen is a set of rotating screen chains assembled from a unique rake tooth plant. Driven by the motor reducer, the rake tooth chain performs a rotating motion in the opposite direction of the water flow.

[0004] When the rake tooth chain moves to the upper part of the equipment, due to the guidance of the groove wheel and the curved rail, each set of rake teeth generates a relative self-cleaning movement, and most of the solid matter falls by gravity. The other part relies on the reverse movement of the cleaner to clean up the debris stuck on the rake teeth.

[0005] In terms of water flow direction, the rake chain is similar to a grille. The rake gap installed on the rake chain shaft can be selected according to the use conditions. When the rake separates the solid suspended matter in the fluid, it can ensure the smooth flow of water. The whole working process can be continuous or intermittent.

[0006] Under the environmental protection industry standard system of the People's Republic of China, there is an industry standard HJ / T 250-2006 that is designed for rotary fine grilles. Under its 4.2.5 item, it has the following test items:

[0007] When the fine grille is running at full load, the noise sound pressure level shall not exceed 75dB(A), and when running at no load, the noise sound pressure level shall not exceed 70dB(A).

[0008] To achieve this test project, a noise sensor device is required to be used. Specifically, the noise sound pressure level values ​​when the fine grille is running at full load and when it is running at no load are obtained through the noise sensor device, and then the noise sound pressure level values ​​are transmitted to the background computer for display via WLAN to determine whether the noise sound pressure level is greater than 75dB(A) when the fine grille is running at full load, and whether the noise sound pressure level is not greater than 70dB(A) when it is running at no load.

[0009] However, in actual use, the existing noise sensor device has many shortcomings. The key is that it is impossible to find a noise sensor that does not collect the noise boost level value. The current noise sensor device relies on the noise sound pressure level value collected by the noise sensor, but the WLAN structure is complex on site, and the number and type of various devices are cumbersome, which often results in loss of status during the collection period. The synchronization cannot immediately understand the current status of the device. The noise sound pressure level value will continuously change when the fine grille is running at full load and when it is running at no load. With the execution of the test, the noise sound pressure level value initially collected in the noise sensor device will gradually become invalid and cannot respond to the correct current status of the fine grille, causing the noise sensor device to gradually lose accuracy, thereby reducing the effectiveness of the detection of the rotating fine grille. Summary of the invention

[0010] To solve the above problems, the present invention provides a control system and method for a rotary fine grille test, which effectively avoids the problem in the prior art that when detecting the rotary fine grille, the noise sound pressure level value initially collected in the noise sensor device gradually becomes invalid and cannot respond to the correct current state of the fine grille, causing the noise sensor device to gradually lose accuracy, thereby reducing the defects in the performance of the rotary fine grille detection.

[0011] To overcome the deficiencies in the prior art, the present invention provides a solution for a control system and method for a rotary fine grid test, as follows:

[0012] A control system for a rotary fine grid test, comprising:

[0013] The noise sensor device, backend computer, main console and reliability listening platform located in the WLAN are all connected via WLAN. The noise sensor device is used to collect the noise sound pressure level values ​​when the fine grille is running at full load and no-load. The main console is used to centrally control various devices in the WLAN and construct a link with the noise sensor device so that changes in the noise sound pressure level value must be copied through the backend computer. The reliability listening platform is used to efficiently detect noise sound pressure level faults.

[0016] The controller is used to transmit the noise sound pressure level value to the background computer for display, so as to determine whether the noise sound pressure level is greater than 75dB(A) when the fine grille is running at full load, and whether the noise sound pressure level is not greater than 70dB(A) when running at no load.

[0017] Furthermore, the noise sensor device also includes a collecting unit, a fault handling unit and a noise sound pressure level value interaction unit running on the controller.

The noise sound pressure level value interaction unit is used to transmit the collected noise sound pressure level values ​​to the main console in the noise sensor device.

[0019] Furthermore, the main console includes a second noise sound pressure level value interaction unit, an online specification unit, a device detection unit and a noise sound pressure level value refresh unit. The second noise sound pressure level value interaction unit is used to collect noise sound pressure level values ​​and is linked to the controller structure. The online specification unit is used to reach constraint specifications between the noise sensor device and several controllers, so that when the noise sound pressure level value changes, the changes synchronized when the background computer copies it must meet the requirements of normal changes. The device detection unit is used to detect the reliability of the approved noise sound pressure level value. The noise sound pressure level value refresh unit is used to detect situations where the reliability of the noise sound pressure level value is different under the noise sensor device, and refresh the noise sound pressure level values ​​with different reliabilities.

[0020] Furthermore, the online specification unit includes a specification performance subunit and a specification agreement subunit. The specification performance subunit is used to perform specification recognition on the noise sensor performance and construct centralized noise sensor specification changes. The specification agreement subunit is used to agree on specifications. The device detection unit includes a command acquisition subunit and a distributed listening unit. The command acquisition subunit is used to instantly obtain noise sensor management command messages. The distributed listening unit is used to be set in the controller to listen to management commands and operation specifications for the noise sensor.

[0025] Step 2: Establish a link with the controller in the noise sensor device and initially set constraint specifications;

[0026] Step 3: Set constraint specifications between each controller and noise sensor device so that different controllers can reach agreement on changes in management specifications with the background computer, to prevent specification incompatibility between unique controllers and cause disconnection and invalidity of controller reliability information;

[0027] Step 4: Obtain the management command of the controller after the link is constructed, and form a command group history record;

[0028] Step 5: A listening unit is set at the management of the linked controller, and the management command is executed externally accordingly, and is adapted to the corresponding management command;

[0029] Step 6: After the adaptation is achieved, the subsequent controller commands are obtained by obtaining the command group history record and the commands obtained by listening, and compared with the detection, the second-level noise sound pressure level value reliability is determined, and a notification message is given if there is no adaptation;

[0030] Step 7: When the reliability of the user's verification changes, the noise sound pressure level value changing unit is run to refresh the different noise sound pressure level values.

[0031] Furthermore, in step 2, the setting of constraint specifications includes:

[0032] Step 2-1: Set the change of noise sound pressure level value to be copied through the background computer, otherwise it will restrict the operation change performance of the equipment;

[0033] Step 2-2: The changes in constraint information meet normal requirements.

[0034] Furthermore, the reliability monitoring platform includes a management command transmission channel, a command time analysis unit, an error reporting unit and a device monitoring unit. The management command transmission channel is used to construct and provide a controller command transmission channel with a dedicated bandwidth. The command time analysis unit is used to analyze the transmission time of the calculation noise sound pressure level value. The notification unit is used to provide a noise sound pressure level value reliability transmission port and perform notifications on information that is not transmitted immediately. The device monitoring unit is used to efficiently monitor the controller that generates noise sound pressure level value reliability problems.

[0035] Furthermore, the control method for the rotary fine grid test also includes:

[0036] A control method for a reliability listening platform;

[0037] The control method of the reliability listening platform includes:

[0038] Step A-1: ​​construct a plurality of device transmission channels and controller command transmission sub-channels respectively;

[0039] Step A-2: The noise sensor device synchronously obtains the device transmission command;

[0040] Step A-3: Adapting a dedicated command transmission subchannel according to the corresponding control transmission command noise sound pressure level value capacity and the noise sound pressure level value effective digits;

[0041] Step A-4: using the noise sound pressure level value capacity and the noise sound pressure level value effective digits, and the dedicated bandwidth controller command transmission channel analytical calculation transmission time value;

[0042] Step A-5: Determine the transmission time value, and notify the unit of the reliability deviation range of the time value;

[0043] Step A-6: The controller command transmission can be continuously received during the reliability deviation range period, otherwise the notification unit is operated and the notification is executed;

[0044] Step A-7: Based on the dedicated bandwidth channel, reversely detect the controller that generates the noise sound pressure level problem.

[0045] Furthermore, the computational equation for analyzing the time-consuming value of the transfer operation in step A-4 is:

[0046] A1={A2*A3*A4} / A5

[0047] Here, A1 is the transmission time value, A2 is the control indicator of the transmission time value in the equation, which is a real number set higher than zero, A3 is the capacity of the controller to transmit the command noise sound pressure level value, A4 is the effective digital value of the controller to transmit the command noise sound pressure level value, and A5 is the command transmission subchannel bandwidth.

[0048] The beneficial effects of the present invention are:

[0049] The present invention constructs a transmission channel in which each transmission controller corresponds to a different command, and then uses the bandwidth-specific performance of the transmission channel to reversely detect the device and controller commands when the analytical operation is time-consuming based on the bandwidth-specific performance of the transmission channel, and efficiently identifies the noise sound pressure level value problem generated, thereby greatly improving the transmission efficiency. It effectively avoids the problem in the prior art that the noise sound pressure level value initially collected in the noise sensor device when detecting the rotating fine grille will gradually become invalid, fail to respond to the current correct state of the fine grille, and cause the noise sensor device to gradually lose accuracy, thereby reducing the defect of the performance of the rotating fine grille detection.
