Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation management system for an insulated vehicle such as a refrigerated vehicle or a refrigerated vehicle for transporting freight such as food and medical goods such as fresh seafood and meat.

[0002]

2. Description of the Related Art In recent years, vehicles such as trucks, buses, taxis, and the like have been equipped with operation control meters for recording the operation state of the vehicles over time. As this operation control meter, there is one disclosed in, for example, Japanese Patent Application Laid-Open No. Hei 7-168555 pertaining to the applicant of the present application. In addition, an operation control meter is also mounted on a cold storage vehicle that transports foods such as fresh seafood and meat, medical products, and the like.

[0003] In the operation management system for an insulated vehicle equipped with the operation controller, the work registration of the crew (driver) of the insulated vehicle is also performed by the registration connected to the operation controller provided near the driver's seat of the vehicle. This is done by the crew operating the terminal.

[0004]

However, in the above-mentioned conventional operation management system for a cold-held vehicle, manual operation is always required, and operation mistakes such as forgetting to operate the crew are inevitable. On the other hand, for example, it is conceivable to detect a work by attaching a door sensor to a door of a luggage compartment formed of a cool box such as a freezer and detecting whether the door is opened or closed. But in this case,
It is necessary to attach a door sensor separately.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above-mentioned matters, and an object of the present invention is to provide an operation management system in an insulated vehicle capable of automatically detecting work without providing a door sensor or the like. That is.

[0006]

According to the present invention, there is provided an operation management system for a refrigerated vehicle configured to record various data necessary for vehicle operation management on a recording medium over time. A temperature sensor is provided in the luggage compartment of the insulated vehicle, and a change state of the temperature detected by the temperature sensor is recorded in the operation control meter, and the door of the luggage compartment is opened based on the recorded change in the state change of the temperature. Judgment of opening and closing is performed, and work is specified.

[0007] As shown by reference numerals C and G in FIG. 3, the doors of the luggage compartment are not opened and closed during traveling, so that the inside of the luggage compartment is in a closed state, so that the temperature change inside is small. When the door is opened, the temperature in the luggage compartment rises sharply, as indicated by symbols D and H. When the unloading is performed, the door remains open.
As indicated by I and K, the temperature rises further.

Therefore, it is possible to determine whether the door of the luggage compartment is closed or open based on the temperature curve representing the temperature change in the luggage compartment. Further, it is possible to identify what kind of work was being performed at that time based on the time when the door is open.

[0009]

Embodiments of the present invention will be described with reference to the drawings. 1 to 3 show one embodiment of the present invention. First, in FIG. 1, reference numeral 1 denotes a freezer truck (an example of an insulated vehicle) having a freezer 2 at a rear portion, and foods such as fish and meat to be frozen (hereinafter referred to as cargo) are placed in a luggage compartment 2 formed by the freezer. 3) are appropriately loaded. 4

In the illustrated example, a portion near the door 5 provided at the rear of the luggage compartment 2, the back side of the luggage compartment 2 (driver's seat side), and the center of the luggage compartment 2 It is provided in three places of the section.

Reference numeral 6 denotes an operation control meter provided near the driver's seat 7 of the refrigerator car 1. This operation management meter 6 is, for example, shown in FIG.
As shown in FIG. 1, various sensors provided in the refrigerator car 1 such as a speed sensor 14, an engine speed sensor 15, and the temperature sensor 4 are composed of a CPU 8, a ROM 9, a RAM 10, a clock circuit 11, a power supply circuit 12, an interface 13, and the like. A memory card 17 serving as a recording medium detachably mounted on the operation control device 6 stores an output signal from the PC and work item information input by the registration terminal 16 (see FIG. 1).
(See FIG. 1).

In FIG. 1, reference numeral 18 denotes a computer as an information processing apparatus,
9, an input keyboard 20, a display 21, a printer (not shown), and the like. Reference numeral 22 denotes a reading device connected to the computer main body 19, which reads the contents of the memory card 17 to be inserted and reads the content of the memory card 17.
To send to. These devices 18 and 22 are installed in, for example, an office of a transportation company.

In FIG. 1, reference numeral 23 denotes a cargo loading / unloading platform provided in a building 24 of a cargo collection and delivery center. Reference numeral 25 denotes a bellows-shaped blocking sheet provided above the platform 23.

Next, the operation of the operation management system in the refrigerator car 1 having the above configuration will be described with reference to FIG. In FIG. 3, the time is plotted on the horizontal axis, the temperature change state of the temperature sensor 4 provided near the door 5 at the rear of the luggage compartment 2 (curve indicated by the symbol T in the figure), and the traveling in the freezer 1. The state (the thick line I shown below the time axis in the figure) and the unloading state (the thick line II shown below the time axis in the figure) are shown.

In the refrigerating vehicle 1 having the above-described configuration, when the operation is started, detection signals from various sensors provided therein are input as data to the operation control device 6 and are stored in the memory card 17 as time passes. Be recorded.

First, when the refrigeration truck 1 delivers the cargo 3 to each of the delivery destinations 25 to 28, the cargo room 2 is opened on the cargo loading / unloading platform 23 provided in the building 24 of the cargo collection and delivery center. Then, the cargo 3 to be delivered is loaded in that state, and when the loading is completed, the door 5 is closed. Luggage compartment 2 immediately after the door 5 is closed
The output of the temperature sensor 4 is not necessarily constant as shown by a curve T in FIG.

That is, immediately after the cargo 3 is loaded into the cargo room 2, the temperature inside the cargo room 2 (hereinafter, simply referred to as the room) is high as shown by reference numeral A in FIG.
Is closed, and the freezing section starts working, as indicated by reference numeral B, the temperature in the room is large and sharply drops. During traveling, as indicated by reference numeral C, the predetermined temperature is maintained while changing slightly. Then, when the door 5 is opened for unloading, as shown by the reference symbol D, the room temperature is large and rapidly rises, and when the door 5 is opened to take out the cargo 3, as shown by the reference symbol E, The temperature rises.

When the vehicle is driven with the door 5 closed again,
As shown by the symbol F, the temperature in the room rapidly decreases, and during traveling, as shown by the symbol G, maintains a predetermined temperature while changing slightly. Hereinafter, when the door 5 is opened, the temperature in the room rises as indicated by reference signs H and K, and when the unloading is performed, the signs I and
As indicated by K, the temperature further increases. During traveling, the temperature does not change significantly as indicated by the symbol J.

In general, when cargo is delivered by the refrigerated truck 1, the refrigerated truck 1 that has left the freight collection and distribution center is only delivered to shops and homes. If there is a portion where the temperature rises sharply in the curve T indicating, it can be determined at that time that the door 5 of the luggage compartment 2 is open and the unloading has been performed. In this case, even if the crew forgets to register the work content through the registration terminal 14, the content can be specified up to that content.

[0019] The temperature rise in the room differs between when the door 5 for unloading is opened for a relatively long time and when the door 5 is not opened for a long time. During the unloading operation, it can be determined whether the unloading takes a long time by observing this temperature condition, and whether the originally planned work was performed according to the predetermined schedule. Can be also determined.

Further, by comparing the temperature change curve T with the vehicle speed change curve, the above judgment can be made more comprehensively. In addition, it is possible to detect a dangerous act (such as running without closing the door 5) during work.

It is needless to say that various studies on the temperature change curve T and the vehicle speed change curve are carried out in a transportation company office or the like after a predetermined delivery operation is completed.

In the above-described embodiment, three temperature sensors 4 are provided in the luggage compartment 2. However, the present invention is not limited to this. The installation place is also arbitrary.

[0023]

According to the operation management system for a cold storage vehicle of the present invention, it is possible to determine whether the door of the luggage compartment is closed or open based on the temperature curve representing the temperature change in the luggage compartment. Since the length of time during which the door is open can be determined, it is possible to specify what kind of work was performed when the door was open. Therefore, even if the crew has forgotten to register the work content, it is possible to specify the work content. Also, there is no need to provide a special sensor for detecting the open / closed state of the door.
