BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a network for centrally managing a plurality of ready-mixed concrete plants having ready-mixed concrete production machines distributed in a plurality of areas of a construction work site and enabling efficient operation. The present invention relates to an abnormality monitoring system for a network-type automated concrete plant that monitors the operation status of each ready-mixed concrete plant in a type-automated concrete plant. The present invention relates to a network-type automated concrete plant that can respond.

2. Description of the Related Art In the ready-mixed concrete production and sales business (mixed concrete business), production, technology, sales management staff, etc. are assigned to a production plant equipped with a stationary concrete material kneading mixer. The company operates a dedicated vehicle (agitator) that is used as an exclusive concrete transport vehicle.

[0003] In such an operation, the capacity for producing concrete is determined by the capacity inherent in the mixer, so that the ability to cope with fluctuations in peripheral demand is extremely poor. That is,
Since the supply capacity within a unit time is constant, if demand is concentrated, supply responsibilities to users cannot be fulfilled.On the other hand, if demand decreases, production equipment cannot exhibit its original capacity, There is a problem that it leads to idleness.

One method of overcoming such a problem is to use a wet mixing method. When using this wet mixing method, the concrete manufacturing plant is not provided with a stationary mixer, but is provided with only a raw material measuring device.
After weighing concrete raw materials such as gravel, cement, water, and admixture, the raw materials are directly put into a concrete mixer truck. Then, the mixture is mixed in a drum of a concrete mixer truck to produce ready-mixed concrete. According to this method, it is not necessary to provide a stationary mixer, and it is possible to reduce the cost of the manufacturing equipment of the concrete plant.

Further, according to the method using the wet mixing method, as described later, compared with the central mixing method which is restricted by the capacity of the stationary mixer,
In the case of the wet mixing method in which raw materials are mixed and mixed by a concrete mixer truck, if the number of mixer trucks is increased, the range of the raw material weighing capacity will not exceed the maximum value.
The production capacity of ready-mixed concrete can be maximized. Further, when the demand decreases, the number of mixer trucks can be reduced to minimize the actual production capacity, and the stationary mixer, which is the heart of the existing plant, can be avoided from becoming an inoperable asset.

Meanwhile, a ready-mixed concrete plant, which is a facility for producing ready-mixed concrete, includes a material storage silo for storing cement, sand, gravel, etc., a material storage bin, a material measuring tank,
It is composed of various devices such as a mixer for mixing concrete and various material conveying devices, and components such as a motor, a solenoid valve, a cylinder, and various sensors are installed in these various devices. The components of these various devices may malfunction due to wear and breakage associated with the operation of the plant, which may hinder plant operation. Therefore, periodic maintenance work is required.

[0007] In order to find out abnormalities of various devices of the ready-mixed concrete plant and abnormalities of the components thereof through regular maintenance and inspection work, humans who have considerable experience are required. The plant is maintained by checking the abnormal operation of the drive unit, temperature rise, load current, etc. while checking the operation status of the plant, and maintaining the plant. However, depending on the location of the occurrence, it takes time to find out, and sometimes the product shipment is stopped.

In particular, when an abnormality occurs in the operation panel or the control system, it is often difficult to determine the cause of the abnormality, and it is not possible to accurately find the abnormal part. As a countermeasure, for example, a method may be adopted in which a facility management rule that incorporates the concept of preventive maintenance is created, and periodic inspections are performed to prevent the occurrence of abnormalities in accordance with the rule.

Recently, the operation control of a ready-mixed concrete plant has been further upgraded using a microcomputer, and information from various sensors, motors, and actuators for grasping the operation state of the plant has been obtained. It is possible to display the processing information calculated based on the fetched operation status. Therefore, maintenance and inspection work is performed using these pieces of information.

Therefore, a ready-mixed concrete plant capable of taking in information from various sensors, motors, and actuators for grasping the operation status of the plant and displaying processing information calculated based on the operation status can be operated unattended. A ready-mixed concrete plant where a facility manager is resident and operated and a ready-mixed concrete plant which is operated unattended are distributed and arranged in a plurality of areas. Then, from the ready-mixed concrete plant where the facility manager is resident and operating, another unmanned ready-mixed concrete plant is maintained and managed.

Other unmanned ready-mixed concrete plants will be managed and maintained.However, unattended ready-mixed concrete plants that are distributed in multiple regions will be unmanned even if monitoring devices are installed to monitor the operating status. for,
When an abnormality occurs, there is a problem that the content of the abnormality cannot be accurately grasped from a ready-mixed concrete plant in which a facility manager is resident and operating.

The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a facility manager who can operate an unmanned ready-mixed concrete plant dispersed in a plurality of regions.

7b is provided with a vibrator in order to improve the flow of sand.
8b is provided with a sensor for confirming opening and closing.

Further, although not shown, the receiving belt conveyor 46 is provided with sensors for checking belt slip, belt meandering, belt speed, and the state of transport of the aggregate. Similarly, a sensor for confirming the position of the distribution damper is provided. Based on signals from these sensors, abnormalities of respective devices in the manufacturing process are detected.

The cement is stored by being pumped from a cement pumping vehicle to a cement storage bin 44c. Similarly to the gravel storage bin 44a and the aggregate storage bin of the sand storage bin 44b, the cement storage bin 44c is provided with a sensor 36c for detecting the full amount and the empty amount. Water is supplied from a water supply pump 49 to a water head tank 48 and stored. The water head tank 48, like other storage bins,
A sensor for detecting the full amount and the empty amount is provided, and water is automatically supplied to the water head tank 48 by a signal from the sensor. Similarly, by the signals from these sensors,
Detects abnormalities in each device in the manufacturing process.

The raw concrete manufacturing machine having such a sensor (FIG. 3) is operated by the plant control signal transmitted from the plant center, as described above. When the driver of the concrete mixer vehicle inputs the identification number of the concrete mixer vehicle into the computer device, a plant control signal is transmitted from the plant center, and the plant control signal controls the sequencer 16 based on the mixing of the ready-mixed concrete. Then, the measuring gates 37a to 37c of the gravel storage bin 44a, the sand storage bin 44b, and the cement storage bin 44c are opened, and the respective materials are measured in the respective measuring tanks 43a to 43c. The water and the admixture are measured in a water measuring tank 40 and an admixture measuring tank 39, respectively. When the weighing is completed, each material is transported in a predetermined order. Aggregate and cement are conveyed by the input belt conveyor 42. The admixture is weighed together with the water and is charged into the concrete mixer truck 18 via the material charging chute 41. Then, the concrete material is conveyed to the destination while being kneaded by the concrete mixer truck 18.

In each of the ready-mixed concrete plants 20a to 20c in which the ready-mixed concrete production machines are installed, plant abnormality monitoring devices 31 to 33 are installed. Metering control unit 2 based on a signal from a sensor provided in the device
The information is collected by 7 and each device operation control unit 28. The monitoring control unit 25 performs a monitoring process of the operation status of the plant based on the content of the information, and the display unit 2

In the plant center 10, a central abnormality monitoring device 30 is installed. The central abnormality monitoring device 30 controls transmission of information on the contents of the abnormality transmitted from the plant abnormality monitoring device of the ready-mixed concrete plant in a remote place. The content is received by the unit 22, analyzed by the main control unit 21, and displayed by the display unit 23. In this manner, the plant center 10 grasps the status of the ready-mixed concrete plants distributed and arranged in a plurality of regions in real time.

FIG. 4 is a diagram showing an example of a plant abnormality display screen displayed on the display unit of the central abnormality monitoring device. FIGS. 5 and 6 show an example of a display screen for displaying detailed contents of the abnormality. FIG. FIG. 7 is a diagram illustrating an example of a display screen displaying an instruction for responding to an abnormal state. An example of displaying an abnormal state in the abnormality monitoring system will be described with reference to these drawings.

For example, if the plant identification number is "No. 1"
When an abnormality occurs in a ready-mixed concrete plant, information on the content of the abnormality is transmitted from the plant abnormality monitoring device 31 installed therein to the central abnormality monitoring device 30 installed in the plant center 10, so that the central monitoring device 30
As shown in FIG. 4, in the display unit 23, the "unit 1" corresponding portion 51 for displaying the occurrence of an abnormality in each plant is highlighted on the plant abnormality display screen 50. Further, in the example of the display screen here, similarly, since an abnormality occurred in the ready-mixed concrete plant having the plant identification number of “No. 25”, the “No.
Is also highlighted. When the buzzer is set to sound to notify the occurrence of an abnormality, the buzzer sound is generated by pressing the “buzzer off” button provided at the lower right of the display screen 50 with the mouse pointer cursor. Stopped. Similarly, a “reset” button at the lower right of the screen is a button for instructing cancellation of the abnormal display.

The part 5 corresponding to the highlighted "No. 1"
When 1 is selected and instructed with the mouse pointer cursor, for example,
Display screen 5 that displays the details of the abnormality as shown in FIG.
3 is displayed. On the display screen 53 of the first unit abnormality contents, the corresponding buttons among the eight “Error No.” display buttons 54 displayed at the top are highlighted. Each "error No." display button 54 is adapted to display the content of 20 items corresponding to one button, and the item display of item number 1 to item number 20 in the initial display. Therefore, the details of the error that occurred in the plant
"Error Nos. 21 to 40"
The display button 55 is highlighted. Therefore, the highlighted “Error Nos. 21 to 4”
When the "0" display button 55 is selected and displayed, the display screen becomes a display screen 56 displaying error numbers 21 to 40, as shown in FIG. 6, and the corresponding error numbers are displayed in reverse video.

Here, when the user further selects and instructs the item 57 of the inverted error number 21 on the display screen 56, a display screen 58 as shown in FIG. 7 is displayed. On the display screen 58, related items among the contents of the abnormality are displayed, and the location of the abnormality, the content of the abnormality, and a method of coping with the abnormality are specifically displayed as messages. This display content can be obtained by taking in information on the details of abnormalities from the weighing device, motor, solenoid valve, actuator, various sensors, etc. of the ready-mixed concrete plant, or displaying the processing information that has been processed based on its operating status. I have.

As described above, for example, “Error Nos.
When the “error No. 21” to “40” display button 55 is highlighted, when the “error No. 21 to 40” display button 55 is selected and displayed, the display screen 56 is displayed. The indicated item appears. Therefore, if it is assumed that the inverted item 57 of the error number 21 [No limit switch is detected when the S gate is open] is highlighted, when this item 57 is instructed to be selected, the display screen 58 is displayed, and the display screen 58 is displayed. A manual that describes the inspection and adjustment methods for the limit switches, cylinders, solenoid valves, and the like to be performed is displayed. As described above, data for displaying the location of the abnormality and the content of the abnormality are created assuming all the events that are expected to occur in the ready-mixed concrete plant.

In the description of the present embodiment, the wet mixing method in which no concrete mixer is installed in each raw concrete plant is described. However, each raw concrete plant installs a concrete mixer. Even in the case of the central mixing system, it is possible to perform the discovery and maintenance management of an abnormal part in the same manner by using a signal from a sensor provided in each device of the ready-mixed concrete plant.

As described above, the operating condition of the unmanned ready-mixed concrete plant distributed in a plurality of areas is monitored, and when an abnormality occurs, the abnormal location and the abnormal condition of the ready-mixed concrete plant are displayed, and the condition is displayed in real time. Since transmission to the plant center is made possible, the operation of the plant that integrates and operates a plurality of ready-mixed concrete plants is facilitated, and it is possible to smoothly respond to abnormal situations. As a response to this abnormal situation, for example, the production of a ready-mixed concrete product that is to be produced in the ready-mixed concrete plant in which the abnormality has occurred can be distributed to another normally operating ready-mixed concrete plant for production. .

Next, the system operation of the network type automated concrete plant including the abnormality monitoring system of the present embodiment will be specifically described. FIG. 8 and FIG.
It is a figure explaining the processing sequence between a plant center and a ready-mixed concrete plant, and FIGS. 10-14 show the operating state of several ready-mixed concrete plants and the operating state of several concrete transport vehicles in a plant center by a matrix display. FIG. 7 is a diagram showing an example of a display screen to be displayed.

With reference to these figures, a specific example of the system operation of the network-type automated concrete plant will be described. The software system for operating the network-type automation plant includes, specifically, an order management subsystem, a CTI (call center system), a customer management subsystem, an operation management subsystem, a sales management subsystem, and a facility management subsystem. It consists of six subsystems. Further, a subsystem of the abnormality monitoring system described above is included.

The operation by these software systems is performed as follows. In brief, the order management system receives a telephone order, an order via a facsimile, an order via the Internet and a mobile terminal (i-mode or the like), and accumulates the order in a core business server. Based on the received information, the operation management system automatically and temporarily assembles a shipping schedule of the next day (a shipping schedule such as a delivery destination, a combination, and the number of stakes in chronological order). The driver of the concrete mixer truck has an MCA radio and an i-mode compliant mobile terminal, and the operation manager of the plant center instructs all vehicles of the concrete mixer truck to use the base plant ( Instruct the ready-mixed concrete plant where the driver should go to work.

When the driver arrives at the designated ready-mixed concrete plant and inputs a car number, which is the identification number of the concrete transport vehicle, from the plant PC, every time the data becomes a plant control signal from the plant center via the network. (Mixing and shipping instruction data) is transmitted to the ready-mixed concrete plant. After that, when the driver presses the start button, the mix data of the plant control signal starts the ready-mixed concrete production machine via the sequencer, the ready-mixed concrete raw material is weighed in the concrete mixer truck, and the work of input is completed . When the work of putting the concrete raw materials into the concrete mixer truck is completed, the measured values of the raw materials are printed, and the delivery slip is output to the printer. Shipment completion data (weighing data)
The data is sent from the computer device (plant PC) on the plant side to the plant center and reflected in the sales management system.

In the ready-mixed concrete business, based on a shipping plan (order table), it is determined whether or not a required number of concrete mixer trucks can be appropriately delivered to a nearby ready-mixed concrete plant at a required time. Efficient operation becomes possible. The operation of the dispatch of the concrete mixer truck does not make much sense in keeping the current position of each vehicle. For example, there is no need to specially assign the vehicle B to the shipment A, and as described above, If sufficient vehicles are allocated to each plant according to the shipping time and the shipping volume, the necessary and sufficient conditions are satisfied.

The driver of each vehicle that drives the concrete mixer truck has a portable terminal conforming to the i-mode. By pressing a function key of the preset portable terminal, the current driver of his / her concrete mixer truck is pressed. State (plant arrival, shipment OK, shipping, shipment completed, on-site arrival,
State, such as forwarding), is notified to the plant center. In the plant center, the notified states are displayed in “color” on the display screen, that is, displayed in different colors.

Specifically, when the driver goes to the plant set the day before and presses the function key for notifying “arrival of the plant” from the portable terminal, the information is sent to the plant center via the Internet, Each shipment item displayed in chronological order and for each plant on the shipment schedule screen of the display device of the LAN terminal device at the center changes to a designated color for arrival at the plant. The basic operation of the operation manager at the plant center is as follows: When the driver of the concrete mixer has been notified of the status "color" of the end of shipment,
This is to select a thin plant with the least number of vehicles in the later shipping schedule table and instruct the driver to return to that plant. The latest status of the operation status of all concrete mixer trucks is identified by their respective "colors" in the shipping schedule display screen displayed in a matrix, so if you use only the shipping schedule and vehicle distribution, Since the worst situation of lack of a vehicle can be avoided, a large number of vehicles can be centrally managed with a small number of personnel.

FIGS. 8 and 9 show a processing sequence between the plant center and the ready-mixed concrete plant as described above. The concrete mixer truck arrives at each of the ready-mixed concrete plants designated the day before, and as shown in FIG. 8, the driver operates the computer device (plant PC) 15 of the ready-mixed concrete plant to remove the concrete mixer truck. When the vehicle number of the identification number to be identified is input and the transmission button is pressed, the shipment data is read from the operation management server 12 via the equipment management server 11 of the plant center, and the shipment data is displayed on the screen.

In the processing sequence of this process, when the vehicle number is input and the “vehicle number notification” button is pressed, the operation management server 12 obtains the operating days from the processing day management file 12a, "Acquire the shipment data of shipment OK for the own plant from the master file 12b. In addition, when the vehicle number is input, an input check is performed, and if it is other than a number, a process of determining an error is performed. When the number of the vehicle number is input, the driver name corresponding to the vehicle number is obtained from the "advanced vehicle / driver correspondence table", and the record matching the condition is read. This condition includes:
For example, the order file 12c is accessed, and the record data of the one that has been shipped OK from the order data and is not used by another vehicle number is read.

From the dispatch / shipment table, each record data of the recipe number, capacity, order number, arrival time, quantity, cumulative quantity, pitch, slip output category, delivery place, customer name, driver instruction is read and displayed, Reads and displays the driver name from the horse mackerel / driver correspondence table,
The data of the processing date is read out from the processing date management file 12a and displayed.

In the operation management server 12, as the transition of the shipping transmission status, the status of the vehicle number notification is displayed in "yellow", and is displayed in "blue" upon normal termination. In addition, it is displayed in “red” upon abnormal termination. If a car number is entered and the target record is not found in the car number notification, an error will occur.
After displaying the error message and confirming it, enter it again.

The user inputs the recipe data, the shipment data is displayed, and inputs the displayed recipe number and capacity. In other words, the same number as the shipping data displayed as the data of the input items of the mixing number and the capacity is input as the input of the mixing data. Also, the input of the combination number and the volume is checked. That is, the recipe number of the displayed shipping data,
We do not accept numbers other than the same number as the capacity. Entering non-numeric characters is an error. Check input of recipe number and volume is OK
In this case, the input of the “plant start” button can be accepted.

Next, as shown in FIG. 9, in the ready-mixed concrete plant, the input of the “plant start” button can be accepted, and the driver operates the ready-mixed concrete plant computer device (plant PC) 15 to “ When the “plant start” button is pressed, the computer device (plant PC) 15 transmits the blending data, the capacity, and the vehicle number to the plant (sequencer) 17. When the “plant start” button is pressed, the “shipment instruction” status is set to “yellow” for the operation management server 12.

As a response from the plant (sequencer) 17, data on each state of "measuring", "measuring response", "discharging", and "discharging completed" are returned from the plant side. In the weighing answer, weighed data is returned. Only the status is returned except for weighing.

Thus, the table is updated.
In addition, the operation management server 12 updates each data of the “status category”, the “order number”, and the “shipping SQNo.” In the control table 12d at the time of starting the plant. “Shipment” is set as the status data of the “status category”. In addition, "status category", "date", "time", "order number", and "shipping SQNo." Are registered in the horseshoe operation status history file 12e.

In the plant (sequencer) 17,
It is repeated up to 3 times from during the measurement to the completion of the release. The weighing data is displayed for each count. When the weighing is completed, the computer device (plant PC) 15 can receive an input of a “print slip” button. "Print slip"
When the button is pressed, the shipping slip is printed by the printer. The method of printing weighing data is changed according to the slip issuance classification of the order data acquired by inputting the vehicle number. When the weighing is completed, the weighing data is registered in the weighing information file 12f. This is performed by the weighing data acquired by the plant equipment being recorded in the operation management database in the operation management server 12. Also, data and total data for each batch are registered. These data are stored in the weighing information file 12f.

At this time, the operation management server 12 updates the data of the “status category”, “order number”, and “shipping SQNo.” In the wheelchair / driver correspondence table 12d. “Shipped” is set as the status data of the “status category”. Also, the “situation category” is updated in the horseshoe operation situation history file 12e. When printing is completed normally, the "slip output" status turns blue.
If printing is abnormally completed, the "slip output" status is set to red.

FIGS. 10 to 14 are diagrams showing an example of a display screen for displaying the operating states of a plurality of ready-mixed concrete plants and the operating states of a plurality of concrete transport vehicles in a plant center in a matrix display. 10 to 1
As shown in FIG. 4, the respective display screens 60, 71 to 74, which are managed and displayed by the operation management server 12, display the operating states of a plurality of ready-mixed concrete plants (plant A, plant B, plant C, plant D). The operation status of a plurality of concrete transport vehicles is displayed in a matrix of cells in different colors to manage the display. That is, the time of the shipping schedule is displayed in the first column 61 displayed on the display screens 60, 71 to 74, and the shipping plan of each of the plurality of ready-mixed concrete plants is correspondingly displayed in the columns (62 to 62) of the matrix. 66).
In addition, a time-series operation plan of each ready-mixed concrete plant is displayed as a row of the matrix. That is, the operation plan of each ready-mixed concrete plant is displayed corresponding to each cell of the matrix. A plurality of concrete mixer trucks are assigned to each cell (operation plan).

FIG. 10 shows a display screen 60 in a state before each concrete mixer truck is assigned to the shipment plan (order) of each ready-mixed concrete plant displayed in each cell. Reference numeral 11 denotes a display screen 71 assigned to a concrete mixer truck arriving at each ready-mixed concrete plant for a part of a shipping plan (order). The assigned cells are colored and displayed on the display screen 71 shown in FIG. 11 to indicate the assigned cells. For example, six concrete mixer trucks have arrived at the plant A, and the shipment plan (order_1 to order_11) displayed in each cell for each of the six concrete mixer trucks.
6) shows a state assigned. Plant B
4 concrete mixer trucks have arrived at
This shows a state in which shipping plans (order_1 to order_4) displayed in each cell are assigned to each of the concrete mixer trucks. Similarly, three concrete mixer trucks have arrived at plant C, and a shipment plan (order_1 to order_3) displayed in each cell is assigned to each of the three concrete mixer trucks. . Further, since one concrete mixer truck has arrived at the plant D, a shipment plan (order_1) indicated by a cell of one concrete mixer truck is assigned.

In this way, for each shipping plan in the ready-mixed concrete plant, the operation status of the assigned concrete mixer truck is displayed in a color-coded manner for each corresponding cell, whereby the color of each cell is displayed. It is confirmed at a glance depending on the distribution. The operating state of the concrete mixer truck is displayed in different colors according to the states of arrival at the plant, approval of shipment, shipment, shipment, arrival at the site, completion of delivery, and return. As described above, the received status information from the concrete mixer truck is color-coded and displayed in each corresponding cell of the matrix corresponding to the concrete mixer truck. A display screen 72 shown in FIG. 12, a display screen 73 shown in FIG. 13, and a display screen 74 shown in FIG. 14 arrive at the plant according to the state transmitted from the concrete mixer truck assigned to the shipment plan of each cell. , Shipping approval,
The status of shipping, shipped, on-site arrival, delivery completed, and returning is displayed.

The change of the display screen of the operation state of each concrete mixer truck will be described together. (1) The shipping schedule created up to the day before is displayed on the screen, and until the "attendance" when horse mackerels are deployed at each plant,
The cells in the matrix display list are in an unorganized state (display screen 60). (2) Concrete mixer trucks are deployed in each plant and allocated to the number of vehicles arriving at the plant and the shipping schedule.
