2. Description of the Related Art In the current ready-mixed concrete manufacturing and sales business (ready-mixed concrete business), a manufacturing plant equipped with a stationary concrete material kneading mixer has manufacturing, technology, sales management staff, etc. A dedicated vehicle (agitator) to be used as a dedicated concrete transport vehicle is deployed and operated.

In such an operation, since the concrete production capacity is regulated by the capacity peculiar to the mixer, the ability to cope with fluctuations in peripheral demand is extremely poor. That is, since the supply capacity within a unit time is constant, when the demand is concentrated, the supply responsibility to the user cannot be fulfilled.
When the demand decreases, the production equipment cannot perform its original ability, which causes a problem that the equipment becomes idle.

As one of the methods for overcoming these problems, there is a method using a wet mixing method. When using this wet mixing method, the concrete manufacturing plant is not provided with a stationary mixer, only the raw material measuring device is provided, and the sand,
After measuring concrete raw materials such as gravel, cement, water, admixture, etc., these raw materials are directly put into the mixing drum of the concrete mixer truck. Then, it is kneaded in a mixing 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 the cost of manufacturing equipment for a concrete plant can be reduced.

Further, according to the method using such a wet mixing system, in the case of the wet mixing system in which raw materials are kneaded by a concrete mixer truck, in contrast to the central mixing system regulated by the capacity of the stationary mixer, the concrete mixing method By increasing the number of mixer trucks, the raw concrete production capacity can be maximized to the extent that the maximum raw material weighing capacity is not exceeded. When the demand decreases, it is possible to minimize the actual production capacity by reducing the number of concrete mixer trucks, and avoid making the stationary mixer, which is the heart of the existing plant, into an inactive asset. .

According to the central mixing system, the ready-mixed concrete plant, which is a facility for producing ready-mixed concrete, has a material storage silo for storing cement, sand, gravel, etc.
It consists of a material storage bottle, a material measuring tank, a concrete mixing mixer, and each material conveying device.By appropriately controlling each of these devices, an appropriate mix of concrete raw materials and an appropriate concrete raw material can be prepared. By kneading, high quality green concrete can be obtained.

Specifically, for example, this operation is performed during the time between the loading of the concrete mixer truck at the concrete plant and the arrival at the unloading site. This time may be unpredictable due to traffic congestion or the like, but the mixing operation is performed during this time. Conventionally, the rotation speed and rotation time of the mixer drum at that time, that is, the rotation speed and rotation time of the mixer drum of the concrete mixer truck during transportation by the concrete mixer truck can be appropriately grasped in the past. As a result, the state of the manufactured fresh concrete, that is, the state of the fresh concrete being transported cannot be properly grasped,
There is a problem that the quality control of the produced ready-mixed concrete cannot be performed sufficiently.

That is, in order to grasp the quality of ready-mixed concrete which is finally manufactured and transported by the mixer drum of the concrete mixer truck, the process of manufacturing and transporting the concrete is performed in the concrete mixer truck (after the concrete raw materials are loaded, There is a problem that the quality of the ready-mixed concrete produced cannot be fully assured because it is not well understood and managed.

The identification information read from the IC chip scanner 41 is input to the computer device 15 of the plant. The position where the IC chip scanner 41 is provided is installed on the wall surface of the plant facility structure in the vicinity of the charging chute 42 for charging the concrete raw material into the concrete mixer truck 18 in each concrete plant (20a to 20c). The concrete mixer truck 18 inputs a chute 42
When the vehicle stops at a position directly below, the IC chip scanner 41 reads the identification information stored in the IC chip 31 and enters the data into the computer device 15 of the plant because the IC chip scanner 41 reads the data. It A vehicle number, a driver identification number, etc. are extracted from the read identification information, and the system identifies the vehicle of the concrete mixer truck 18. At the same time, it is confirmed that the concrete mixer truck 18 has arrived at the concrete plant and is in a standby state.

Next, the outline of the system operation will be described step by step. That is,
(1) A driver of the concrete mixer truck 18 (hereinafter, also referred to as a driver), when going to work, for example, as shown in FIG.
To enter the employee code. That is, in the state where "attendance" is selected (by operating the selection button 45) on the liquid crystal display screen 43 of the operation terminal device 37, by pressing the "confirm" button 44, the employee code input screen is displayed. , Enter the employee code. When the employee code is entered, the entered employee code information is acquired at predetermined time intervals by the information of the operation terminal device and the respective sensors (GPS signal receiving device, rotation detection sensor, electronic flow meter) equipped on the vehicle. Along with the various types of information stored therein, it is converted into digital data of a predetermined format by the function of the data converter of the information processing device, and the information is transmitted to the plant center via the wireless communication line. The system receiving this information links the vehicle of the concrete mixer truck 18 and its driver. As a result, on the PC screen of the plant center (PC screen for performing plant control), the state of the vehicle is displayed as being identified as "going to work". The operation terminal device of the concrete mixer car 18 displays the number of mileages (odometer) at the end of the work on the previous day.

(2) In addition, the GPS receiver installed in each concrete mixer truck 18 provides the information about the current position, moving direction, and speed of the vehicle together with the status information obtained from each sensor of the concrete mixer truck 18. , Is transmitted every predetermined time, and is being acquired in real time at the plant center 10. Therefore, in the plant center 10, the vehicle of the concrete mixer truck 18 is preset from the position information of the GPS signal in the information transmitted from the concrete mixer truck 18, for example, the latitude and longitude of the network plant 20a. Radius 100 from point
It is determined whether or not the vehicle has entered the zone within m, and when the vehicle enters the zone, the system (the operation management server 12 of the plant center 10) determines that the state of the concrete mixer truck 18 is “arriving at the plant”. Since the plant center receives the information of each vehicle in almost real time (once every 30 seconds), it uses this information to identify the status (status) identified as necessary. It is reflected in the shipping plan table and the map screen PC in the system operation, such as displaying them in different colors. In addition, position information that changes from moment to moment of the concrete mixer truck 18 is superimposed and displayed on the map screen.

(3) And ready-mixed concrete plant 2
The concrete mixer truck 18 arriving at 0a further arrives at the ready-mixed concrete plant 20a
When the raw concrete plant is stopped under the loading gate to load raw materials (FIG. 6), the IC chip scanner 41 on the raw concrete plant side can read the information of the tape type IC chip 31 mounted on the vehicle body. Since the state (the state where the IC chip can be read is entered), the IC chip scanner 41 reads the information of the IC chip 31 (the vehicle identification information of the concrete mixer truck 18, the personal identification information of the driver). The vehicle identification number read by the IC chip scanner 41 is reflected (automatic input of vehicle number) in the shipping computer device 15 on the ready-mixed concrete plant 20a side. When the employee code (vehicle number) is stored in the IC chip for operation, the operation of entering the employee code from the in-vehicle type operation terminal device installed in the driver's seat by the driver at the beginning of work is omitted. Or just press the confirm button. Since the computer device 15 is connected to the system of the plant center 10 (equipment management server 11, operation management server 12, order management server 13) by a dedicated line, I
The information of the IC chip read from the C-chip scanner 41 is transmitted via the computer device 15 of the plant and is reflected on the shipping plan screen. As a result, in the plant center 10, the IC chip 41
Vehicle identification number (and employee code) stored in
The state in which is read by the IC chip scanner 41 of the plant is recognized as "standby".

(4) When the driver (driver) presses the "start" button of the computer device 15 of the plant in the "standby" state. This signal is transmitted to the plant center 10, and the plant center 10 transmits a plant control signal for charging the concrete raw material to be loaded into the concrete mixer truck 18 in accordance with the shipping schedule scheduled by the order.
The sequencer 16 starts the operation by this plant control signal and operates the concrete manufacturing facility 17. This is because the plant center 10 side transmits a plant control signal to the plant sequencer, whereby the control on the ready-mixed concrete plant 20a side proceeds. As a result, by receiving the information for confirming the reception of the plant control signal, the plant center 10 recognizes that "raw material is loaded" and changes the status to "loading".

(5) As the driver's operation at this time, in order to accelerate the ingestion of the concrete raw material into the mixer drum, the operation lever is operated to start the concrete mixer 1 before the start of the concrete raw material injection.
8 is to switch the drum rotation speed to medium speed rotation (1500). The state in which the drum rotation speed is switched by performing this operation is detected by the rotation detection device 33 of the mixer drum of the concrete mixer truck 18.
That is, the rotation detection device 33 of the mixer drum identifies whether the rotation direction of the drum is “forward” or “reverse”, also recognizes the drum rotation speed, and transmits the status information to the plant center 10 in real time. Therefore, the plant center 10 recognizes this state. Normally, it takes about 5 minutes to load concrete raw materials, so at the stage where 5 minutes have passed after the situation of "loading" was recognized, the drum rotation detection device 33 was in the "forward direction" and When it is detected that the rotation has reached the predetermined speed, in this case, the plant center 10 changes the recognition of the state of the concrete mixer truck 18 from "loading" to "mixing". The mixing time of the concrete raw material is predetermined as a standard for guaranteeing a predetermined quality according to the concrete product to be shipped. Here, therefore, each data of the rotation speed and the rotation time of the drum is used as the state information of the concrete mixer truck 18 from the concrete mixer truck 18 in real time (every predetermined time).
Since it has been transmitted, the status information is received and stored in the server and managed in the plant center 10. Further, as will be described later, this data is separately used as one of quality data of shipped products as a manufacturing process record (kneading process record).

(6) When the concrete mixer truck 18 loads concrete raw materials and leaves the concrete plant, the GPS received by the GPS receiver is also used.
The status information including the latitude and longitude information of the concrete mixer truck 18 obtained from the signal is the concrete mixer truck 18
Since it is transmitted from, the state information is received and judged. That is, since the status information of the concrete mixer truck 18 is received at the plant center 10 in real time, at the plant center 10, from the latitude / longitude information in the status information of the concrete mixer truck 18, the concrete mixer truck 18 is Fresh concrete plant 20 (after loading concrete raw materials)
When it deviates from the zone of 100 m in radius of a, this is discriminated as a "running" state. If necessary, the actual movement of the concrete mixer truck 18 is
Subsystems are provided so that points can be grasped point by point on the map screen of the system (computer device) operation screen in the plant center 10.

(7) Further, in the system, the address information of the location of the delivery site of the fresh concrete product kneaded by the mixer drum of the concrete mixer truck 18 is converted into latitude and longitude information in advance and displayed on the map screen. Since it is mapped, when the point of latitude and longitude information of the moving concrete mixer truck 18 enters within 100 m of the latitude and longitude of the delivery site, operation of the operation terminal device of the system (computer device) in the plant center 10 The state of the screen changes to the state that the concrete mixer truck 18 has arrived at the site.

(8) When the fresh concrete is unloaded from the concrete mixer truck 18, the mixer drum of the concrete mixer truck 18 is reversely rotated, so this state is detected. That is, when the concrete mixer truck 18 is in the "on-site arrival" state, the concrete mixer truck 18 is
When the rotation detection device 33 detects that the rotation direction is "reverse", the plant center 1
The system of 0 identifies the state of the concrete mixer truck 18 as being “under unloading” (start of unloading) when it first recognizes the state.

(9) Subsequently, the concrete mixer truck 1
8 detects the unloaded state from the state information transmitted in real time. In other words, in the concrete mixer truck 18, after unloading the fresh concrete,
This condition is detected because the driver cleans the mixer drum. The state in which the driver has washed the fresh concrete charging chute of the vehicle is detected from the state information of the water amount detection signal of the electronic flow meter in the state information transmitted in real time. When the electronic flow meter of the cleaning water tank detects a prescribed amount of water from the state information, this data is transmitted to the plant center 10, so that the system (computer device) in the plant center 10 changes the state of the concrete mixer truck 18 into the state. Switch to the "chute wash" state.

(10) The work is completed when the concrete mixer truck 18 arriving at the site is unloaded and the chute cleaning is completed, and the driver operates the operation terminal device 3 mounted on the vehicle.
By pressing the "delivery completed" button 44 (FIG. 5) at 7, the information is transmitted to the plant center 10. When the "delivery completed" button is pressed and this data is transmitted from the operation terminal device, the system (computer device) in the plant center 10 changes the state of the concrete-manipulating concrete truck 18 to the "delivery completed" state. To identify.

(11) Further, continuing from the state of "delivery completed", next, in the system (computer device) in the plant center 10, the concrete mixer truck 1
When the point of the latitude / longitude information indicating the current position of 8 is 100 m or more away from the latitude / longitude point of the site, the state of the concrete mixer truck 18 is
The status is "Returning". At this time, the concrete mixer truck 18 is instructed to the plant for loading the raw concrete material to be shipped next. This instruction (destination) is displayed on the liquid crystal display screen 43 of the operation terminal device 37.

(12) Then, the point of the latitude / longitude information of the concrete mixer truck 18 obtained from the longitude / latitude information of the concrete mixer truck 18 received by the GPS receiver of the concrete mixer truck 18 is the next concrete raw material. After approaching the ready-mixed concrete plant 20a for material loading, the procedure described in (2) above is returned to and repeated.

(13) When the operation of the concrete mixer truck 18 is temporarily disabled due to a driver's break, an accident of the concrete mixer truck 18, or the like, the driver mounts it on the concrete mixer truck 18 concerned. Of the operation buttons of the operating terminal device 37 that are
By pushing the button "inoperable", the system of the plant center 10 is notified that the state of the concrete mixer truck 18 is "inoperable". When the ready-mixed concrete product cannot be completely unloaded at the delivery site of the ready-mixed concrete product and the residual concrete is to be disposed of at a predetermined place where the ready-mixed concrete is to be disposed, it is similarly mounted on the concrete mixer truck 18. By pressing the button for processing the remaining concrete out of the operation buttons of the operating terminal device, the system of the plant center 10 indicates that the concrete mixer truck 18 is in the state of "processing the remaining concrete". Notice.

(14) Further, the concrete mixer truck 1
When the driver finishes the work of one day in 8,
The driver inputs the number of miles traveled at the end of the day from the operation terminal device 37. As a result, the plant center 10
System is notified that the state of the concrete mixer truck 18 is in the "work away" state, and the system (computer device) in the plant center 10 is notified of this.
Identifies.

In this way, the status information of the concrete mixer truck 18 is acquired in real time and the system is operated. By using the acquired status information in this system operation, the daily driver work report is automatically created. It can be carried out. That is, as described above, by accumulating the state information of the concrete mixer truck 18 in the plant center 10 for each concrete mixer truck 18 and processing each data obtained from the state information, for example, In addition, the daily driving report of each vehicle can be automatically created. Also, it is possible to create data for displaying the quality of manufactured ready-mixed concrete. I: Calculated from the travel distance registered on the travel distance operation terminal. Mileage = (Mileage when leaving work)-(Mileage when going to work) II: Working time graph "Working time" = "Loading""Mixing""Unloading"
Etc. Total time "Running time" = "Running", "Returning", "Remaining concrete processing"
Etc. Total time "rest time" = Total time of statuses other than the above III: Kneading time (printed on product slip) Calculated by the rotation speed of the mixer drum and the mixing time. The kneading time varies depending on the components of the concrete raw material.

Next, the processing on the system (computer device) side in the plant center 10 and the processing on the ready-mixed concrete plant will be described. As previously mentioned,
When the driver of the concrete mixer truck 18 goes to work,
When the employee code is input from the in-vehicle type operation terminal device installed in the driver's seat, the information of the input employee code is the information of the operation terminal device and the respective sensors (GPS signal receiving device, rotation detection) equipped on the vehicle. Along with various types of information acquired by sensors and electronic flow meters), the data is converted into digital data of a predetermined format by the function of the data converter of the information processing apparatus, and the information is transmitted to the plant center via the wireless communication line.

The concrete mixer truck 18 arrives at the concrete plant 20a, and the arrived concrete mixer truck 18 further moves to the ready-mixed concrete plant 20a.
In order to load the raw materials, the IC chip scanner 41 on the ready-mixed concrete plant side reads the IC chip 31 and enters the “standby” state when the plant is stopped under the loading gate of the plant, and the driver operates the computer device 15 of the plant. When you press the "Start" button of. This signal is transmitted to the plant center 10, and the plant control signal is transmitted from the plant center 10. Thereby, the concrete making machine is operated.

No staff for operating the concrete manufacturing machine is resident at the ready-mixed concrete plant 20a, and a manufacturing instruction (plant control signal) for operating the concrete manufacturing machine 17 is transmitted from the plant center 10 as electronic information. The signal is sent as a signal, and the concrete making machine 17 is operated by the sequencer 16 via the computer device 15 of the plant.

Further, the plant control signal transmitted from the plant center 10 is transmitted to the computer device 1 of the plant.
Controlling the sequencer 16 via 5, the concrete manufacturing machine 17 fully automatically measures the concrete raw materials in accordance with the contents to be shipped, and the concrete mixer car 18
Material input to the is completed. As described above, the driver (driver) completes the ready-mixed concrete by the wet mixing method in which the drum of the concrete mixer truck is rotated at a high speed for a certain period of time, and carries it into the site.

Until now, the distribution system of ready-mixed concrete for concrete mixer trucks, which had been mainly routed from departure from the factory to which the concrete mixer truck belonged and then returning to the factory to which it belonged again, was Greatly diversified by networking. For example, the system can be operated so that the vehicle carried in from the A plant to the X site loads the ready-mixed concrete at the B plant, delivers it to the Y site, and then returns to the C plant to prepare for the X site. Therefore, the unit cost of the ready-mixed concrete distribution can be reduced due to the increase in the operating rate of the vehicle.

Each ready-mixed concrete plant 20a
In this case, ready-mixed concrete is manufactured and loaded on a concrete transportation vehicle. In this case, the concrete mixer truck 18 read by the IC chip scanner 41 is identified with respect to the computer device 15 which transmits and receives data to and from the plant center 10. By inputting the number, the identification number and the plant number for identifying the ready-mixed concrete plant 20a are transmitted to the plant center 10, and the plant control signal is waited for from the plant center 10. Send to. The sequencer 16 controls the ready-mixed concrete manufacturing machine 17,
The raw concrete making machine 17 produces raw concrete from the stored concrete raw materials.

In the plant center 10, when the equipment management server 11 receives the identification number and the plant number of the concrete mixer truck transmitted from the ready-mixed concrete plant 20a, as will be described later, the concrete number is given by the identification number. The state in which the mixer truck arrives at the ready-mixed concrete plant 20a is registered, and a plant control signal for manufacturing ready-mixed concrete to be loaded into the concrete mixer truck is taken out from the operation management server 12 and the order management system 13 and transmitted.

In the plant center 10, the facility management server 11, the operation management server 12, and the order management system 13 are connected by a LAN device (not shown) to form a network system. A plurality of terminal devices operated by a person are connected. These facility management server 11 and operation management server 1
2 and the system including the order management system 13 collectively manage the generation and transmission of plant control signals to be transmitted to the ready-mixed concrete plant in a centralized manner.

The facility management server 11 here provides a processing function of controlling the ready-mixed concrete plant by performing data communication processing between a plurality of ready-mixed concrete plants and a plant center. Together with the facility management server 11, it manages the condition of the concrete transport vehicle and the condition of the ready-mixed concrete plant. In addition, the order management system 13 provides a processing function of receiving an order from a customer and managing a mixing state of ready-mixed concrete to be manufactured, a shipping amount, and the like in accordance with the customer.

Thus, in the plant center 10,
The management of generation and transmission of plant control signals to be transmitted to each of the ready-mixed concrete plants 20a to 20c is centrally controlled, and the received identification number of the concrete mixer truck 18 (identification information written in the IC chip 31 is received. ) Identifies each of the plurality of concrete mixer trucks, and controls the ready-mixed concrete plant including the mixing state of the raw concrete material to be transported by each identified concrete mixer truck 18, the content amount, and the destination instruction. A plant control signal for, for example, the ready-mixed concrete plant 2 of the corresponding plant number.
0a is transmitted.

In the plant center 10,
The operation management server 12 manages the operation states of the plurality of concrete mixer trucks 18 by the state information (vehicle identification information, position information, information of each sensor) transmitted from the concrete mixer trucks 18. 9, the operation plans of a plurality of ready-mixed concrete plants 20a, 20b, 20c are displayed in a time-series matrix for each ready-mixed concrete plant, as shown in FIGS. The color-coded display of the operating state and the operating state of the plant by the state signals transmitted from the plurality of concrete mixer trucks that transport the ready-mixed concrete manufactured in. In addition to this, the status information of each concrete mixer truck 18 is displayed in different colors on the map display screen.

Specifically, for example, the operation management server 12
Is a display device (not shown) for displaying the state information of the concrete mixer truck by color, and a display processing device (not shown) for controlling the display device and displaying the operating state of the concrete mixer truck and the operating state of the plant together. ) And a reception processing unit (1 that receives status information from the concrete mixer truck).
1), the display processing device displays a plurality of each ready-mixed concrete plant in a matrix column on the display screen of the display device, and operates each ready-mixed concrete plant in time series as rows of the matrix. Along with displaying the plan, a plurality of respective concrete mixer trucks are assigned to the operation plan of each ready-mixed concrete plant corresponding to each cell of the matrix, and status information from the concrete mixer truck received from the receiving device. Are color-coded and displayed in the corresponding cells of each of the matrices corresponding to the concrete mixer truck. The operation state of the concrete mixer truck here is displayed in different colors according to the states of plant arrival, shipment approval, shipping, shipped, site arrival, delivery completed, and returning.

As a result, in the plant center,
The operating states of a plurality of ready-mixed concrete plants and the respective states of concrete transport vehicles can be easily and surely grasped, and the production and delivery of ready-mixed concrete can be carried out efficiently. In addition, by collectively controlling the ready-mixed concrete plants that are distributed and arranged in a plurality of areas of the construction work site, efficient operation becomes possible.

Next, a specific example of system operation on the plant center side will be described. 7 and 8 are diagrams for explaining the processing sequence between the plant center and the ready-mixed concrete plant, and FIGS. 9 to 13 are the operation states of the ready-mixed concrete plants and the operation of the concrete transport vehicles in the plant center. It is a figure which shows an example of the display screen which displays a state and a matrix display.

With reference to these figures, a specific example of system operation of the network type automated concrete plant will be described. The software system for operating the network type automated plant is, specifically, an order management subsystem, a CTI (call center system), a customer management subsystem, an operation management subsystem, a sales management subsystem, an equipment management subsystem. It consists of 6 subsystems.

The operation by these software systems is performed as follows. In brief, the order management system accepts telephone orders, FAX orders, Internet orders, and mobile terminal (i-mode, etc.) orders, and stores them in the core business server. Based on these received information, the operation management system automatically tentatively assembles the next day's shipping schedule (shipping plan such as delivery destination, mix, and number of cubic meters in time series). For the driver (driver) of the concrete mixer truck, the operation manager of the plant center, via the operation terminal device 37 mounted on the concrete mixer truck 18, asks the vehicle of each concrete mixer truck 18 of the next day. Instruct the base plant (green concrete plant that the driver should come to).

When the concrete mixer truck 18 driven by the driver (driver) arrives at the instructed ready-mixed concrete plant, the identification information of the IC chip 31 of the concrete mixer truck 18 is read by the IC chip scanner 41, and the plant is read. When it is input via the PC, data (mixture and shipping instruction data), which is a plant control signal from the plant center, is transmitted to the ready-mixed concrete plant via the network. Then, when the driver presses the "start" button, the mix data of the plant control signal activates the ready-mixed concrete manufacturing machine 17 via the sequencer 16, and the ready-mixed concrete raw material is weighed in the concrete mixer truck and input. The work is completed.
When the work of putting the concrete raw material into the concrete mixer truck is completed, the shipment completion data (measurement data) is stored in the computer device (plant P) of the plant side.
It is sent from C) to the plant center and reflected in the sales management system.

As described above, the concrete mixer truck 18 is equipped with the operation terminal device operated by the driver. The display device of the operation terminal device shows the current state of the concrete mixer truck 18 (plant arrival). , Shipping OK, shipping, shipped, on-site, forwarding, etc.) according to the status information transmitted from the concrete mixer truck 18 in real time.
It is displayed corresponding to the contents determined in. Further, in the plant center 10, each state is displayed on the display screen by “color”, that is, color-coded.

More specifically, when a driver (driver) arrives at a concrete plant and the IC chip scanner 41 reads the identification information of the IC chip 31, the information is sent to the plant center 10. Then, on the shipment schedule screen of the display device of the LAN terminal device of the plant center 10, each shipment item displayed in time series and for each plant is changed to the designated color for the arrival at the plant. The basic operation of the operation manager at the plant center 10 is
The state of shipment from the concrete mixer truck 18 "color"
Is to instruct the driver to return to that plant by selecting the thinnest plant with the smallest vehicle distribution in the later shipping schedule table. The latest operating status of all concrete mixer trucks is identified by their respective "colors" on the shipping schedule display screen that is displayed in a matrix, so if you focus only on the shipping schedule and vehicle distribution, Since the worst case of lack of vehicles can be avoided, it is possible to manage a large number of vehicles in a centralized manner with a very small number of personnel.

7 and 8 show the processing sequence between the plant center and the ready-mixed concrete plant as described above. The concrete mixer arrives at each ready-mixed concrete plant instructed the day before, and as shown in FIG.
The identification information of the IC chip 31 is read, and the computer device (plant PC) of the ready-mixed concrete plant 1
When the identification information of the concrete mixer truck is input via 5, the equipment management server 11 of the plant center 10
The shipping data is read from the operation management server 12 via the, and the shipping data is displayed on the screen.

In the processing sequence of this process, the operation management server 12 has the processing date management file 12a.
The operating date is acquired from the “vehicle allocation / shipping table” master file 12b, and the shipping data of shipping OK for the own plant is acquired. Read the record that meets the conditions, based on the car number data. As this condition, for example, the order file 12c is accessed, and the record data of the order accepted data that has been shipped OK but is not used by another vehicle number is read out.

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

In the operation management server 12, the state of the vehicle number notification is displayed in "yellow" as a transition of the shipping transmission status, and is displayed in "blue" when it is normally completed. Also, it is displayed in "red" at abnormal termination. Depending on the vehicle number, if the target record is not found in the vehicle number notification, an error will occur. Redisplay after displaying the error message and confirming.

The composition data is input, shipping data is displayed, and the displayed composition number and volume are input. That is, as the combination data input, the same number as the shipping data displayed as the data of the input items of the combination number and the capacity is input. In addition, input check of combination number and capacity is performed. That is, the recipe number of the displayed shipping data,
Only the same number as the capacity will be accepted. It is an error to enter anything other than numbers. Input check of recipe number and capacity is OK
In this case, the input of the "start" button for plant operation can be accepted.

Next, as shown in FIG. 8, in the ready-mixed concrete plant, the input of the "start" button can be accepted, and the driver operates the computer device (plant PC) 15 of the ready-mixed concrete plant,
When the "start" button is pressed, the computer device (plant PC) 15 transmits a plant control signal including formulation data, capacity, and vehicle number to the plant (sequencer) 17. In addition, for the operation management server 12,
When the "Start" button is pressed, the "shipment instruction" status becomes "yellow".

As a response from the plant (sequencer) 17, the data of each state of “measurement in progress”, “measurement response”, “during discharge”, and “release completed” is returned from the plant side. The metered response returns the metered data. Only status is returned except for weighing.

As a result, the table is updated. Further, the operation management server 12 updates each data of “status classification”, “order number”, and “shipment SQ No.” in the horse-car / driver correspondence table 12d at the start of plant operation. "Shipment" is set as the status data of "status classification". Further, "status classification", "date", "time", "order number", and "shipment SQ No." are registered in the horse mackerel operation status history file 12e.

In the plant (sequencer) 17,
Repeated up to 3 times from weighing to completion of discharge. The measurement data is displayed for each number of times. When the weighing is completed, the computer device (plant PC) 15 can accept the input of the “slip print” button. "Voucher print"
When the button is pressed, the shipping slip is printed by the printer. The method of printing the weighing data is changed according to the slip issue classification of the order data obtained by entering the vehicle number. When the weighing is completed, the weighing data is registered in the weighing information file 12f. This is performed by recording the measurement data acquired by the plant equipment in the operation management database in the operation management server 12. In addition, data and total data for each batch are registered. These data are accumulated in the measurement information file 12f.

At that time, in the operation management server 12, each data of "status classification", "order number", and "shipment SQ No." in the horse-car / driver correspondence table 12d is updated. "Shipment completed" is set as the status data of "status classification". In addition, the "status classification" is also updated in the horse mackerel operation status history file 12e. When printing is completed normally, the "Voucher output" status is changed to blue.
If printing ends abnormally, the "slip output" status is displayed in red.

9 to 13 are views 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 matrix display in the plant center. As shown in FIGS. 9 to 13, each of the display screens 50, 61 to 64 managed and displayed by the operation management server 12 has a plurality of ready-mixed concrete plants (plant A, plant B, plant C, plant D).
