Description

[Technical field]

[0001] The present invention relates to a soil remediation system and management device for remediating soil containing contaminants. [Background technology]

[0002] In-situ remediation techniques are known that remove contaminants in a treatment area (also called in-situ) that contains contaminated soil and groundwater (see, for example, Patent Documents 1 to 3). In-situ remediation techniques that purify soil and groundwater in-situ can be implemented at low cost compared to methods that excavate soil and remove contaminants from the excavated soil. However, the remediation costs for in-situ remediation techniques are largely comprised of management costs, including labor costs, and tend to increase the longer the remediation period.

[0003] Known monitoring technologies applied to conventional in-situ remediation methods include, for example, a system equipped with an e-mail system that notifies a remote location of an alarm when an equipment such as a pump stops abnormally (see Patent Document 1), and a system that obtains monitoring data such as the concentration of contaminants contained in the soil and temperature in real time at a remote location (see Patent Document 2). Another known monitoring technology is a method for remotely controlling the ON / OFF operation of equipment in a soil remediation apparatus (see Patent Document 3).

[0005] Conventional in-situ purification devices are constructed according to the purification method for each treatment target area. Therefore, there is a problem that the in-situ purification device must be constructed according to the treatment target area, which increases the costs for installation and management.

[0006] An object of the present invention is to provide a soil remediation system and management device that are capable of centrally managing a plurality of treatment target areas that are subjected to different remediation methods. [Means for solving the problem]

[0008] According to the present invention, a plurality of soil purification apparatuses can be remotely and centrally managed and controlled. Even if the plurality of soil purification apparatuses are different types, each soil purification apparatus can be individually managed and controlled by generating control information according to a purification method corresponding to each soil purification apparatus.

[0009] In a further aspect of the present invention, the management device may generate the control information corresponding to each of the soil purification apparatuses based on information relating to a control format set in each of the soil purification apparatuses.

[0010] According to the present invention, by using information relating to preset control formats to generate control information appropriate for each soil purification apparatus, it is possible to individually manage and control a plurality of soil purification apparatuses of different formats.

[0011] In one aspect of the present invention, the management device includes a display unit that displays a purification state of each of the grounds in each of the treatment target areas based on the detection value.

[0012] According to the present invention, the states of a plurality of processing target regions can be grasped in a unified manner via the display unit.

[0013] One aspect of the present invention is a management device that manages a soil purification system that purifies ground in a plurality of treatment target areas, and is characterized in that it generates control information for controlling each of the soil purification devices based on detection values ​​indicating operating states obtained from a plurality of soil purification devices installed in the plurality of treatment target areas, in accordance with a purification method corresponding to each of the soil purification devices, and has a control unit that individually controls each of the soil purification devices based on the control information.

[0014] According to the present invention, it is possible to provide a management device that remotely and centrally manages and controls a plurality of soil purification apparatuses. According to the present invention, even if the plurality of soil purification apparatuses are different types, each soil purification apparatus can be individually managed and controlled by the management device that generates control information according to the purification method corresponding to each soil purification apparatus.

[0017] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A soil remediation system and a management device according to an embodiment of the present invention will now be described with reference to the drawings. The soil remediation system manages and controls the remediation of ground in a plurality of treatment target areas.

[0018] 1 and 2, the soil purification system 1 includes a plurality of soil purification apparatuses 2 and a management device 10 that manages the plurality of soil purification apparatuses 2. The plurality of soil purification apparatuses 2 are provided in a plurality of treatment target areas where contaminants are contained in the soil or groundwater. The plurality of soil purification apparatuses 2 and the management device 10 are connected by a network W.

[0019] The soil purification device 2 performs purification treatment using a treatment method according to the type of contaminants contained in the soil and groundwater in the treatment target area and the state of contamination. The soil purification device 2 is composed of devices according to the treatment method, such as biological treatment, chemical treatment, heat treatment, soil gas suction, and groundwater pumping treatment. The soil purification device 2 includes, for example, purification equipment 3 that purifies the soil and groundwater in the treatment target area, a detection unit 4 that detects monitoring data related to purification, and a drive unit 5 that transmits and receives information related to control and drives the purification equipment 3.

[0020] The purification equipment 3 includes purification equipment such as a heater, a pump, a blower, an inverter, and a valve that are controlled according to the method for purifying the soil in the treatment area. The purification equipment 3 is controlled by digital signals or analog signals.

[0021] The detection unit 4 includes a sensor that detects the state of the purification equipment 3 and various sensors that detect the state of the soil and groundwater in the area to be treated. The detection unit 4 performs measurements required for controlling the purification equipment 3, such as the water level, flow rate, concentration, and temperature. The detection unit 4 outputs detection data using a digital signal or an analog signal.

[0022] The driving unit 5 drives the purifier 3 based on, for example, a control signal received from the management device 10. The driving unit 5 includes a control circuit such as a PLC or a sequencer, and supplies driving power according to a control amount to the purifier 3 from a power supply device (not shown) based on the received control signal. The driving unit 5 generates an analog or digital control signal for driving the purifier 3 according to the type of the purifier 3 based on the control signal.

[0023] The driving unit 5 is remotely controlled by the management device 10. The driving unit 5 converts the detection data detected by the detection unit 4 during initial setting into numerical data according to the contents of the detection data. The driving unit 5 also aggregates the detection data output from the detection unit 4, converts it into a detection value including numerical data, and transmits it to the management device 10.

[0024] The management device 10 generates control information for controlling each soil purification device 2 in accordance with the purification method corresponding to each soil purification device, based on the detection values ​​of the operating conditions acquired from each soil purification device 2. The management device 10 individually controls each soil purification device 2 based on the control information. The management device 10 is, for example, an information processing terminal constituted by a personal computer or the like. One or more management devices 10 may be provided. The management devices 10 may be provided at multiple locations via the network W.

[0025] The management device 10 includes, for example, a control unit 12 that controls the soil purification apparatus 2, a memory unit 14 in which programs and data related to control are stored, an operation unit 16 that accepts operations related to the control of the soil purification apparatus 2, and a display unit 18 that displays the operating status of the soil purification apparatus 2.

[0026] The storage unit 14 is realized by a storage medium such as a RAM, a ROM, a HDD, a flash memory, etc. The operation unit 16 is an input device such as a keyboard or a mouse that accepts input of information for initial setup of the soil purification apparatus 2. The operation unit 16 may be integrated with the display unit 18 when the display unit 18 is configured by a touch panel type display device.

[0027] The display unit 18 is a display device such as a liquid crystal display, an organic EL display, etc. The display unit 18 may be configured separately from a personal computer, a tablet terminal, a smartphone, etc.

[0028] The control unit 12 is realized, for example, by a processor such as a CPU executing a program (software) stored in the storage unit 14. Some or all of the functions of these components may be realized by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or may be realized by a combination of software and hardware. The program may be stored in a storage device such as an HDD or flash memory in advance, or may be stored in a removable storage medium such as a DVD or CD-ROM, and installed by inserting the storage medium into a drive device.

[0029] The control unit 12 generates control information corresponding to the purification devices 3 included in each soil purification apparatus 2. The control unit 12 generates control information corresponding to each soil purification apparatus 2 based on information related to the control format set in each soil purification apparatus 2. The control unit 12 acquires information related to the purification devices 3 based on input operations from the operation unit 16, as described below. Based on input operations from the operation unit 16, the control unit 12 sets the type of each purification device 3, the signal format (digital, analog, etc.) controlled by the drive unit 5, the current value, the voltage value, the display value after calculation corresponding to the input value, the threshold value for issuing an alarm, etc.

[0030] The control unit 12 refers to the set values, generates control information for the purification equipment 3 based on the detection values, controls the drive unit 5 via the network W, and individually controls each of the purification equipment 3 of the multiple soil purification devices 2. The control unit 12 performs predetermined control over the soil purification equipment 2 based on a predetermined threshold value based on the detection values. The control unit 12 generates an image showing the purification state of each ground in each treatment target area based on the detection values, and displays it on the display unit 18.

[0031] As shown in FIG. 3, the control unit 12 generates a setting image M1 for inputting information about each sensor in the purifier 3 and the detector 4 during initial setting before operating the system, and displays the image on the display unit 18. The setting image M1 is, for example, a display image of a website displayed via the network W (the same applies to the setting images shown below). The setting image M1 has input fields for, for example, an identification number (device number) given to each sensor in the purifier 3 and the detector 4, the name (device name) of each sensor in the purifier 3 and the detector 4, and an abbreviation (device abbreviation) of the purifier 3 for display. The operator inputs a setting value from the operation unit 16. The setting image M1 has input fields for, for example, the type of signal to be input / output.

[0032] The input / output signals (I / O) are, for example, digital input and digital output (DI / DO), DIO (Digital I / O), analog input and analog output (AI / AO), and other signals. In addition, the setting image M1 has input fields for various data such as the interface voltage, current value range, maximum value, minimum value, display value after calculation corresponding to the input value, threshold value for issuing an alarm, coordinates, etc. Setting values ​​are input from the operation unit 16 according to the input fields in the setting image M1. The control unit 12 generates a control signal corresponding to the purification device 3 based on the input setting value.

[0033] 4, the control unit 12 generates a setting image M2 to be displayed on the display unit 18 during operation management. In the setting image M2, the detection values ​​detected by the detection unit 4 are displayed, and the system is provided with a function of importing a layout image (PDF or DXF) for intuitively identifying the layout relationship of the purification devices 3 as the positions of the original devices with respect to the displayed detection values.

[0034] 5, in the setting image M2, the detection values ​​are displayed in real time for each soil purification apparatus 2. The setting image M2 makes it easy to understand the operating status of the soil purification apparatus 2. Furthermore, the setting image M2 may display, as necessary, a graph showing the presence or absence of an alarm, the operating status of the equipment, and fluctuations in the detection values, or an image of a button for switching to an image from a surveillance camera.

[0035] 6, the control unit 12 generates a setting image M3 for changing the setting values ​​and controlling the on / off of each purification device 3 to be displayed on the display unit 18 during operation management of the soil purification apparatus 2. The setting image M3 displays the name of the soil purification apparatus 2, and input fields and buttons for changing the setting values ​​and controlling the on / off of the purification devices 3 that the soil purification apparatus 2 has.

[0036] As shown in Fig. 7, the administrator can log in for each managed area based on the management image K1 and manage and control the soil purification apparatus 2 that purifies the ground for each treatment target area on the website. As shown in Figs. 8 and 9, the administrator can monitor the operating status of each purification device 3 of the soil purification apparatus 2 based on the management images K2 and K3. As shown in Fig. 10, the administrator can monitor the each purification device 3 of the soil purification apparatus 2 with a camera based on the management image K4. As shown in Fig. 11, the administrator can monitor alarms that have occurred in the soil purification apparatus 2 based on the management image K5.

[0037] The management device 10 can generate control information corresponding to the purification method corresponding to each soil purification device 2 based on detection values ​​obtained from multiple soil purification devices 2 installed in multiple treatment target areas, and can individually control each soil purification device 2 based on the control information.

[0038] As described above, the soil remediation system 1 allows for centralized management of multiple treatment target areas using different remediation methods. Compared to conventional monitoring and control systems that have been developed primarily for the purposes of abnormality detection and maintenance, the soil remediation system 1 has versatility and can control multiple soil remediation apparatuses 2 using different remediation methods. The soil remediation system 1 allows the management device 10 to be easily incorporated into soil remediation apparatuses 2 currently being used for in-situ remediation. The soil remediation system 1 can be applied to a website on the network W that manages in-situ remediation currently in operation.

[0039] The soil remediation system 1 is versatile and can simultaneously monitor and control multiple soil remediation devices 2 operating with different in-situ remediation methods, such as pumping groundwater and suctioning soil gas, on the same system. The soil remediation system 1 can be applied to a website for managing the operation of multiple in-situ remediation techniques. The operating status of each soil remediation device 2 may be made public to general users via the network W.

[0040] The soil remediation system 1 can grasp the remediation status of multiple soil remediation devices 2 in real time through remote operation. The soil remediation system 1 can obtain predicted values ​​and facilitate setting changes through cooperation with remediation analysis and diagnosis tools and machine learning devices. The soil remediation system 1 can remotely monitor and control multiple soil remediation devices 2, reducing management costs and shortening the construction period required for remediation.

[0041] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment and can be modified as appropriate without departing from the spirit of the present invention. For example, the soil purification system may be applied to the management and control of not only soil purification equipment but also other treatment facilities, plants, factories, etc. [Explanation of symbols]
