Description

[Technical field]

[0001] The present invention relates to technology relating to a batcher plant used in tunnel excavation, and more specifically, to a plant information management system that enables information relating to a batcher plant to be checked remotely and that enables the batcher plant to be operated remotely. [Background technology]

[0002] Approximately two-thirds of Japan's land area is mountainous, and as a result many sections of roads and railways (hereafter referred to as "roads, etc.") pass through mountainous areas. To build roads, etc. in mountainous areas, it is common to employ either the cut earth method, in which part of the slope is excavated, or the tunnel method, in which the interior of the natural ground is hollowed out. While the tunnel method tends to have a higher construction cost (construction cost per length of road, etc.) than the cut earth method, it also tends to require less excavated soil (i.e., the amount of soil discharged), and has the advantage of allowing greater freedom in the linear planning of roads, etc. (for example, shortcuts can be taken), and more than 10,000 tunnels have been constructed in Japan to date.

[0003] Until the 1970s, the mainstream construction method for mountain tunnels was the "sheet pile method," which combined steel arch supports with wooden sheet piles to support the natural ground, but now the New Austrian Tunnelling Method (NATM), which actively utilizes the strength of the natural ground, has become mainstream. NATM's main feature is its design philosophy that relies on the strength of the natural ground (arch effect), which allows the scale of the tunnel supports to be smaller than with the conventional sheet pile method, and also reduces construction costs by improving construction speed.

[0004] Here, we will briefly explain the excavation procedure using NATM. First, the tunnel face is excavated. In the case of blasting excavation, a drill jumbo is used to drill a hole and load explosives (dynamite), and then the workers and the drill jumbo evacuate before blasting. On the other hand, in the case of mechanical excavation, the tunnel face is cut by a free-section excavator. The excavation length (one span length) of one cycle varies depending on the support pattern set according to the strength of the ground, but generally excavation is performed with a span length of 1.0 to 2.0 m. After one span length is excavated, the debris is removed (debris removal) by a dump truck (or rail method) while "scrambling" is performed to remove unstable ground parts (loose stones, etc.). After the debris removal, mirror spraying or primary concrete spraying is performed, and then steel supports are erected as necessary (depending on the support pattern), secondary concrete spraying is performed, and then rock bolts are installed. The primary concrete spraying work, secondary concrete spraying work, and rock bolting work are carried out for the excavated span length, i.e., the circumferential surface of the tunnel in the unlined portion (the surface extending from the side wall to the top).

[0005] In this way, NATM is a construction method in which excavation is carried out one span (1.0 to 2.0 m) at a time by repeating a series of processes (hereinafter referred to as the "excavation cycle") such as excavation (for example, drilling holes in the face and blasting), removing debris, erecting steel supports, spraying concrete, and driving rock bolts.

[0006] Reducing the time required for an excavation cycle (hereafter referred to as "cycle time") leads to a reduction in the overall construction period and construction costs of a tunnel, so work at the construction site focuses on reducing this cycle time. For example, to shorten the cycle time, sprayed concrete is quickly transported to the tunnel face after the shearing is removed (or after the steel supports are erected). Meanwhile, the start time of each process that makes up the cycle time changes depending on the progress of the day, so the start time of concrete spraying is not fixed every day. Therefore, the timing of sprayed concrete is measured according to the condition of the tunnel face. In addition, tunnel excavation is generally carried out continuously for 24 hours in day and night shifts, so it is not realistic to request work from a commercial concrete manufacturing company at night.

[0007] Under these circumstances, the main method of producing the shotcrete used in tunnel excavation is by using a batcher plant (hereinafter, simply referred to as a "tunnel batcher plant") installed in the yard of the construction site. For this reason, various technologies related to batcher plants have been proposed. For example, Patent Document 1 proposes a method of producing shotcrete while controlling the temperature of the concrete mix. [Prior art documents] [Patent documents]

[0008] [Patent Document 1] JP 2020-196217 A Summary of the Invention [Problem to be solved by the invention]

[0009] The tunnel batcher plant is equipped with a "control panel" as shown in FIG. 7(a). The control panel is also equipped with an "operation panel" as shown in FIG. 7(b), and various controls for the tunnel batcher plant can be performed by operating various operation buttons on the operation panel. Furthermore, the tunnel batcher plant stores information on various materials to be mixed, such as cement, water, coarse aggregate, fine aggregate, admixture (fly ash, etc.), and admixture (AE water-reducing agent, etc.), as data (hereinafter referred to as "mixture material data") every time it produces sprayed concrete. Then, this mix material data can be displayed on a "display screen" provided on the control panel as shown in FIG. 8(a), and a report of the mix material data can also be printed out by operating an operation button (for example, the "daily accounting button") as shown in FIG. 8(b).

[0010] In this way, various processes can be performed by using the control panel of the tunnel batcher plant, but on the other hand, the desired process cannot be performed unless the worker goes to the control panel. For example, mixing of sprayed concrete is started by pressing an operation button on the control panel, but to time the start of mixing, it is necessary to check the surrounding conditions such as the state of material input and the agitator vehicle, but such checking work may not be able to be performed sufficiently in front of the operation panel. Therefore, the worker has to check various conditions while moving around and then go back to the control panel, which increases the amount of movement and takes unnecessary time to start mixing.

[0011] Also, as mentioned above, by operating the control panel, the material mix data can be displayed on the display screen or printed out, but similarly, the material mix data cannot be checked without going to the control panel. Furthermore, the material mix data printed on the form is on paper, and so-called data processing such as daily tallying, cumulative processing, and subtraction of the amount received from the amount used cannot be performed. Normally, a "receipt and payment ledger" is created to manage material mix data, as shown in Figure 9, but up until now, it has been common to manually input (transcribe) the printed material mix data into so-called spreadsheet software such as "Microsoft Excel" or "Google Spreadsheet" to create the receipt and payment ledger.

[0012] The object of the present invention is to solve the problems associated with the prior art, that is, to provide a plant information management system that can obtain information about a tunnel batcher plant by remote operation without having to go to the control panel. [Means for solving the problem]

[0013] The present invention was made with a focus on storing various electronic information (hereinafter referred to as "plant information") about a tunnel batcher plant that can be processed by a computer in a database server (e.g., a database server on the cloud) and controlling the tunnel batcher plant using a portable terminal device, and is an invention based on an unprecedented idea.

[0014] The plant information management system of the present invention is a system that outputs plant information, and includes a transmission means, a central storage means, and a terminal device. The batcher plant produces sprayed concrete while weighing each material for each batch based on a preset concrete mix and a unit production amount per batch, and can store plant information including the weighing results of each material. The transmission means constituting the plant information management system of the present invention is provided in the batcher plant and is a means for transmitting plant information. The central storage means is a means for storing the plant information transmitted by the plant transmission means, and the terminal device is a means for outputting the plant information stored in the central storage means.

[0015] The plant information management system of the present invention may further include a ledger creating means for managing the amount of materials used for sprayed concrete based on the plant information stored in the central storage means. A "material management ledger", which is one of the ledgers created by the ledger creating means, includes the amount of each material received for sprayed concrete, the daily weighing results for each material for sprayed concrete, and the cumulative amount used.

[0016] The plant information management system of the present invention can also output plant information including inspection data (results of dynamic load inspection of the batcher plant). In this case, the ledger creation means creates a "measurement accuracy management ledger" for managing the measurement accuracy of the batcher plant based on the inspection data. The measurement accuracy management ledger includes the "measurement results (measurement results by the batcher plant)" for each material related to the sprayed concrete. When the measurement results are within the allowable range of the predetermined mixture indication value, it can be determined that the results of the dynamic load inspection are normal.

[0017] The plant information management system of the present invention can also output plant information including abnormality information of the batcher plant. In this case, the ledger creation means creates a "plant management ledger" for managing the state of the batcher plant based on the abnormality information. The plant management ledger includes the "type of abnormality" and "time of occurrence" that occurred in the batcher plant.

[0018] The plant information management system of the present invention can also display the "operation power status" of the batcher plant, the "number of consecutive times when automatically mixing sprayed concrete (hereinafter referred to as automatic batch)", and the "current batch number" as plant information on a portable terminal device. In this case, the terminal device has an operation means capable of controlling the batcher plant, and an automatic batch start button is displayed as the operation means. Then, when the operation power status is displayed as "on", operating the start button causes the batcher plant to start mixing the sprayed concrete by remote control.

[0019] The plant information management system of the present invention can also display the "mixer power supply status" and "mixer gate operation status" as plant information on a terminal device. In this case, when the mixer power supply status is displayed as "on" on the terminal device and the mixer gate operation status is displayed as "automatic", the batch automatic start button is operated and the batcher plant starts mixing the sprayed concrete by remote control.

[0020] In the plant information management system of the present invention, the terminal device may have a mix input means. In this case, when a concrete mix is ​​input using the mix input means, the batcher plant produces sprayed concrete based on the input concrete mix.

[0021] The plant information management system of the present invention may be configured such that the terminal device has a unit amount input means. In this case, when the unit amount input means is used to input a unit production amount per batch, the batcher plant produces shotcrete based on the input unit production amount. Effect of the Invention

[0022] The plant information management system of the present invention has the following advantages. (1) Because plant information is collected and stored, the operating status of the batcher plant (mixture tables, material management books, plant management books, measurement accuracy management books, etc.) can be monitored remotely. In particular, when an abnormality occurs in the batcher plant, a specialist engineer can quickly check the plant management books and estimate the cause from the data history, which means that a rapid response can be made. (2) A material management ledger (receipt / payment ledger) can be created without manually inputting (transcription) printed material mix data, thereby reducing the workload of the ledger creator. (3) The batcher plant can be controlled remotely from the terminal device without having to go to the control panel. As a result, the batcher plant can be controlled remotely from the terminal device without having to go to the control panel. As a result, the batcher plant can be sprayed while checking the surrounding conditions, such as the state of material input and the agitator vehicle, and timing the start of mixing.

[0024] An embodiment of a plant information management system according to the present invention will be described with reference to the drawings.

[0025] One of the technical features of the present invention is the output of "plant information." Here, plant information refers to various information related to the batcher plant (tunnel batcher plant) that produces the sprayed concrete used in tunnel excavation. For example, as shown in Figure 1, this plant information can include "weighing results," "received amount," "inspection data," "abnormality information," "plant operation information," and "mixture data."

[0026] Of these, the weighing results include the weighing results and the weighing date and time of each material (cement, water, coarse aggregate, fine aggregate, admixture, admixture, etc.) related to concrete production per batch, while the incoming amount includes the incoming amount of each material required for concrete production and the incoming date, etc. Also, the inspection data is the result of the dynamic load inspection of the tunnel batcher plant, and includes the "actual weight" of each material related to concrete production per batch actually measured and the inspection date, etc., while the abnormality information includes the time when the abnormality occurred and the type of abnormality, etc.

[0027] On the other hand, the plant operation information includes various statuses related to the operation of the tunnel batcher plant. For example, as shown in Figure 1, the plant operation information can include the "continuous number of batches" of automatic batches, the "current batch number" of the continuous number at the time of operation, the "operation power status (on / off)", the "mixer power status (on / off)", and the "mixer gate operation status (automatic or manual)".

[0028] FIG. 2 is a block diagram showing the main configuration of the plant information management system 100 of the present invention, and FIG. 3 is a model diagram showing the arrangement of each device constituting the plant information management system 100 of the present invention. As shown in this figure, the plant information management system 100 can be configured to include a terminal device 200, a central device 300, and a batcher plant 400. As shown in FIG. 3, the terminal device 200 and the central device 300 are connected to each other so as to be able to communicate with each other wirelessly or by wire, and similarly, the central device 300 and the batcher plant 400, and the terminal device 200 and the batcher plant 400 are also connected to each other so as to be able to communicate with each other wirelessly or by wire. As shown in FIG. 3, a plurality of terminal devices 200 (four devices in the figure) can be connected to each other so as to be able to communicate with each other, and two or more central devices 300 can be connected to one batcher plant 400 so as to be able to communicate with each other.

[0029] The terminal device 200 constituting the plant information management system 100 can be manufactured as a dedicated device, or a general-purpose computer device can be used. That is, a computer device executes arithmetic processing by a predetermined program, thereby performing processing specific to each means. This computer device includes a processor such as a CPU, memories such as a ROM and a RAM, and some also include input means such as a mouse and a keyboard, and a display. The computer device can be configured, for example, by a personal computer (PC) or a server, and in particular, it is preferable to configure it by a tablet PC such as an iPad (registered trademark) or a portable terminal device such as a smartphone. If the computer device includes a display, the display can also be used as the output means 240 of the terminal device 200.

[0030] Below, each of the main components constituting the plant information management system 100 will be described in detail.

[0031] (Bacher plant) The batcher plant 400 constituting the plant information management system 100 is a conventionally used general "tunnel batcher plant" equipped with a plant transmission means 410 and a plant reception means 420. This tunnel batcher plant produces sprayed concrete while measuring each material for each batch based on a preset concrete mix and the amount of concrete produced per batch (hereinafter simply referred to as "unit production amount"). For this reason, the tunnel batcher plant is equipped with a material measuring means 430 that measures each material, a concrete mixing means 440 (e.g., a mixer) that mixes each input material, and the like.

[0032] Furthermore, the plant-side storage means 450 provided in the tunnel batcher plant stores the results of the material weighing means 430 weighing each material ("weighing results" shown in Fig. 1) every time sprayed concrete is produced (i.e., for each batch), and also stores plant information such as "abnormal information," "plant operation information," and "mixture data" shown in Fig. 1. However, conventional plant-side storage means 450 stores plant information in the storage device of a special industrial computer built into the control panel, and has not previously been able to transmit plant information as data to other equipment.

[0033] Therefore, in the plant information management system 100 of the present invention, the batcher plant 400 is provided with a plant transmission means 410, that is, the plant transmission means 410 transmits the plant information as data to the central device 300 (central transmission / reception means 320). The batcher plant 400 is also provided with a plant reception means 420. As described below, the batcher plant 400 can be remotely operated by operating the operation means 210 of the terminal device 200. That is, when the plant reception means 420 receives a "control signal" transmitted from the terminal device 200 (terminal transmission / reception means 230), the control signal is transmitted to the control means of the batcher plant 400, and the control means further controls the actuator according to the control signal, so that the material measuring means 430 measures each material and the concrete mixing means 440 mixes each material.

[0034] (central unit) 2, the central unit 300 is configured to include a central storage means 310 and a central transmission / reception means 320. Of these, the central transmission / reception means 320 is a means for receiving plant information transmitted from the plant transmission means 410 of the batcher plant 400 and transmitting the received plant information to the central storage means 310. The central transmission / reception means 320 can also transmit, in response to an inquiry from the terminal unit 200, predetermined information out of the plant information stored in the central storage means 310 to the terminal unit 200 (terminal transmission / reception means 230).

[0035] The central storage means 310 is a means for storing plant information, and may utilize a storage device of a general-purpose computer or may be constructed in a database server. When constructed in a database server, it may be placed in a local network (LAN: Local Area Network), but it is particularly preferable to use a cloud server that stores information via the Internet (i.e., wireless communication).

[0036] (Terminal Device) 2, the terminal device 200 is configured to include an operation means 210, a bookkeeping means 220, a terminal transmission / reception means 230, and an output means 240. Among these, the terminal transmission / reception means 230 is a means for receiving plant information transmitted from the central transmission / reception means 320 of the central device 300, and transmitting a "control signal" for controlling the batcher plant 400 to the plant reception means 420. The output means 240 is a means for outputting plant information and various books described later, and can be configured using a display, a printer, or the like.

[0037] The ledger creation means 220 is a means for creating various ledgers such as a "material management ledger", a "plant management ledger", and a "measurement accuracy management ledger" based on the plant information stored in the central storage means. As will be described below, each of the various ledgers is composed of different information. Therefore, the ledger creation means 220 queries the central device 300 (central storage means 310) for information required for creating each ledger, receives the information via the central transmission / reception means 320 or the terminal transmission / reception means 230, and creates a specific ledger. The ledger creation means 220 is not limited to being installed in the terminal device 200, and can also be installed in the central device 300. In this case, it is preferable that the terminal device 200 is designed to receive and output various ledgers created by the ledger creation means 220 of the central device 300.

[0038] The "material management ledger" is equivalent to the conventional "receipt and payment ledger" and is a ledger that can manage the amount of each material used in the sprayed concrete. For example, the material management ledger shown in Figure 4 is configured as a table in which information on each material, such as cement (C1), water, coarse aggregate (G1), fine aggregate (S1), admixture (fly ash, etc.), and admixture (AE water reducing agent, etc.), that is mixed into the sprayed concrete, is handled as a record for each batch, and the record is displayed in multiple rows. The information on each material includes the "amount used" per batch, the "cumulative amount used (for example, the cumulative amount used since the start of construction)," the "amount received (amount delivered)," and the "remaining amount." The material management ledger can also be configured to include the amount of concrete produced per batch and the type of concrete. The types of concrete can include normal type concrete, Nsec type concrete, and mortar.

[0039] When creating a material management ledger, the ledger creation means 220 first queries the central storage means 310 to receive the measurement results and mixture data from the plant information. Then, the measurement results are treated as the "usage amount," the "accumulated usage amount" is calculated based on the past usage amount, and the "remaining amount" is calculated based on this accumulated usage amount and the incoming amount input by the operator, and then a table-type material management ledger is created. Conventionally, plant information was stored in a special industrial computer built into a control panel, so that a user had to go to the control panel, print out the mixture material data as plant information, and manually input the printed information into a spreadsheet software such as "Microsoft Excel" while visually checking the information. However, according to the plant information management system 100 of the present invention, plant information is transmitted and received as "data" that can be processed by a computer, so that a material management ledger can be created (or output) automatically without the need for visual manual input, and furthermore, in any location where there is a receiving environment.

[0040] The "measurement accuracy control ledger" is a ledger that can grasp the results of dynamic load inspection of the tunnel batcher plant. In the dynamic load inspection, the "measurement result" of each material per batch measured by the material weighing means 430 of the tunnel batcher plant is determined to be normal when it is within the allowable range of the predetermined blending instruction value (planned blending data), and is determined to be abnormal when it is not. Therefore, when creating the measurement accuracy control ledger, the ledger creation means 220 first queries the central storage means 310 to receive the measurement result and blending data of the plant information. Then, the "difference" is calculated based on the measurement result and the blending instruction value ("standard blending value" in FIG. 5), and the difference is made into one record, and a table in which the record is represented in multiple rows is created as the measurement accuracy control ledger. For example, the measurement accuracy control ledger shown in FIG. 5 is configured as a table in which the "actual weight (instruction value)" and "difference (error)" of each material are made into one record.

[0041] The "plant management ledger" is a ledger that allows one to grasp the state of the tunnel batcher plant, particularly abnormal states. This plant management ledger is created based on the "abnormality information (Fig. 1)" as plant information. Therefore, when creating the plant management ledger, the ledger creation means 220 first queries the central storage means 310 to receive abnormality information from the plant information. Then, a combination of "type of abnormality" and "time of occurrence" is treated as one record, and a table that represents the record in multiple rows is created as the plant management ledger. Since the plant management ledger can be created (or output) anywhere as long as there is a receiving environment, when an abnormality occurs in the tunnel batcher plant, a specialized engineer can quickly estimate the cause of the occurrence from the data history, which means that a quick response is possible.

[0042] The operation means 210 is a means for controlling the tunnel batcher plant by remote operation. In this case, the output means 240 of the terminal device 200 displays "plant operation information" as plant information. For example, in FIG. 6, the output means 240 displays "operation power status", "set batch (continuous number of times)", "current batch (current batch number of times)", "operation power status", "mixer power status", "mixer gate operation status", and "abnormal state" included in the plant operation information, and further displays "batch automatic" as the operation means 210 (operation control means 211). Note that "on" and "off" are displayed as the operation power status, "on" and "off" are displayed as the mixer power status, and "stopped / manual" and "automatic" are displayed as the mixer gate operation status. Note that the operation power status indicates "on / off" of the tunnel batcher plant power, the mixer power status indicates "on / off" of the concrete mixing means 440 (mixer), and the "automatic" of the mixer gate operation status means that the mixer gate can be automatically operated.

[0043] The operation means 210 is configured to include an operation control means 211, a mix input means 212, a unit amount input means 213, and the like. Among these, the operation control means 211 is a means for instructing the tunnel batcher plant to start concrete production. For example, "Batch automatic" shown in FIG. 6 functions as a "batch automatic start button", so to speak, and when this batch automatic part is touched (or pressed) on the panel, the tunnel batcher plant starts concrete production. More specifically, when the operator operates the batch automatic start button, a "control signal (in this case, a signal to start concrete production)" is transmitted from the terminal device 200 (terminal transmission / reception means 230), and the control signal received by the plant reception means 420 is transmitted to the control means of the batcher plant 400, and this control means further controls the actuator, thereby starting measurement by the material measurement means 430.

[0044] The control by the operation control means 211 may be subject to various restrictions. For example, concrete production cannot be started when the tunnel batcher plant operation power is not turned on. Therefore, the operation control means 211 may be operated to start concrete production only when "on" is displayed on the output means 240 as the operation power status. Alternatively, the operation control means 211 may be operated to start concrete production only when "on" is displayed as the mixer power status and "automatic" is displayed as the mixer gate operation status in addition to "on" as the operation power status. Furthermore, the operation control means 211 may be operated to start concrete production when "on" is displayed as the operation power status and "automatic" is displayed as the mixer gate operation status.

[0045] The mixture input means 212 is a means for instructing the concrete mixture when the tunnel batcher plant produces concrete. More specifically, when the operator operates the mixture input means 212 (touching the panel or pressing a button), a "control signal (in this case, a concrete mixture signal)" is transmitted from the terminal device 200 (terminal transmission / reception means 230), the control signal received by the plant reception means 420 is transmitted to the control means of the batcher plant 400, and the control means further controls the actuator, causing the material measurement means 430 to measure each material based on the mixture.

[0046] The unit amount input means 213 is a means for instructing the unit production amount (amount of concrete produced per batch) when the tunnel batcher plant produces concrete. More specifically, when the operator operates the unit amount input means 213 (touching the panel or pressing a button), a "control signal (in this case, the unit production amount of concrete)" is transmitted from the terminal device 200 (terminal transmission / reception means 230), the control signal received by the plant reception means 420 is transmitted to the control means of the batcher plant 400, and this control means further controls the actuator, so that the material measurement means 430 measures each material based on the mix. [Industrial Applicability]

[0047] The plant information management system of the present invention can be used when producing various types of concrete used in tunnel excavation, such as the first concrete spraying and the second concrete spraying in tunnel excavation. The present invention can efficiently carry out mountain tunnel construction, and by extension, can efficiently build construction infrastructure such as roads and railways. Considering this, the invention can be expected to not only be used industrially, but also to make a great contribution to society. [Explanation of symbols]
