DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an abnormality management system for managing an abnormal temperature of a container.

[0002]

2. Description of the Related Art Conventionally, in managing abnormal temperature of a container, an alarm device such as a lamp or a buzzer is attached to each container and monitored.

[0003]

However, when the container is housed in a vehicle or a warehouse, there is a problem that the monitoring of the alarm is not satisfactory due to the difficulty in monitoring the alarm.

[0004] It is an object of the present invention to provide a container abnormality management system which is easy to monitor and can surely manage the occurrence of abnormal temperature and the malfunctions related to its detection.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention is to be mounted on the top of a container , and when the inside of the container is at a normal temperature, it is determined whether the container is normal by infrared or the like by radio. a transmitter for transmitting continuously a signal at shall attached to the vehicle and warehouses are enclosures of containers, located above the respective container in the housed state the at individual correspondence between each container A receiver is provided for receiving signals from the transmitters, and an alarm device is attached to the central monitoring location of the container and warns an abnormality of the container when the receiver does not receive the normality determination signal.

[0006]

According to the present invention, when the inside of the container is at a normal temperature, a normal judgment signal is continuously transmitted from the transmitter of the container to the outside, and when the temperature becomes abnormal, the normal judgment signal is not transmitted. . Each normality determination signal is received by the receiver in an individual correspondence relationship with each container, and when the normality determination signal is no longer received by any of the receivers, an alarm device corresponding to the receiver alerts the abnormality of the container. Is done. In addition, the transmitter is judged to be normal by radio such as infrared rays
Because the signal is transmitted, the connection failure due to the wired connection is
No problem such as disconnection occurs. In addition, this transmitter
Attached to the top of the tena, while the receiver is a vehicle or warehouse
At the top of each container. here
In the upper part of the container, other luggage etc. are usually placed
Because it is an empty space that will not be
The normal judgment signal sent from the
Can reliably receive this normality judgment signal.
In addition, it is said that luggage etc. contact or collide with the transmitter
A situation can be avoided, and damage to the transmitter can be prevented.

FIG. 1 is a simplified diagram showing an abnormality management system when a container is mounted on a vehicle as a first embodiment of the present invention, and FIG. 2 is a simplified circuit diagram of the abnormality management system.

In FIG. 1, reference numeral 1 denotes a vehicle, and 2 denotes a container accommodated in a predetermined accommodation position of the vehicle 1. Reference numeral 3 denotes a transmitter, which is attached to the outer surface of the top of each container 2, and continuously transmits a normality determination signal by infrared rays upward when the inside of the container 2 is at a normal temperature. Reference numeral 4 denotes a receiver, which is attached to the inner surface of the top of the vehicle 1 so as to face the transmitters 3 of the containers 2 respectively, receives an infrared signal of the transmitter 3 facing the receiver, converts it into an electric signal, and sends it out. AC is an AC power supply, and DC is a DC power supply.

Reference numeral 5 denotes an alarm monitor as an alarm device, which is attached to the driver's cab 6 of the vehicle 1 and is individually connected to each receiver 4 by a signal line 7. Referring to FIG. 2, BZ denotes a buzzer, and PL denotes an alarm lamp, which warns that the container 2 has reached an abnormal temperature by individually corresponding to each container 2. SWA is a setting operation switch for enabling / disabling the AC power supply AC for each operation of the buzzer BZ and the number display, and SWB is a normally-closed alarm operation switch, and each receiver 4 outputs a normal judgment signal. The buzzer BZ and the alarm lamp P
L is deactivated, and these are activated when the normality determination signal is no longer output.

In the above configuration, if the transmitter 3 is opposed to the receiver 4 as shown in FIG. 1 while each container 2 is being transported or the like, and each transmitter 3 transmits a normality determination signal, When the normality determination signal is received via each receiver 4, each alarm operation switch SWB is opened and the buzzer BZ and the alarm lamp PL
Does not work. When any one of the containers 2 reaches an abnormal temperature from this state, the normality determination signal of the transmitter 3 of the container 2 stops. Accordingly, the signal of the receiver 4 opposed thereto is lost, the alarm operation switch SWB is closed, the buzzer BZ is activated, and an alarm is issued, and the accommodation position number of the container 2 can be known by the alarm lamp PL. . Even when the temperature detection system of the container 2, the transmitter 3, the receiver 4, or the like breaks down, the buzzer BZ is similarly activated and alerted by the failure of the receiver 4 to transmit a normality determination signal, and The storage position number can be known from the alarm lamp PL. When the container 2 is not stored in the predetermined storage position, the alarm and the like for the container 2 do not operate by opening the setting operation switch SWA.

FIG. 3 is a simplified diagram showing an abnormality management system when a container 2 is stored in a warehouse as a second embodiment of the present invention.

In FIG. 1, reference numeral 8 denotes a warehouse, in which the container 2 shown in FIG. Numeral 9 denotes a receiver, which is equivalent to the receiver 4 in FIG. 1, and is mounted on the inner surface of the ceiling of the warehouse 8 so as to face each transmitter 3 of each container 2. Reference numeral 10 denotes an alarm monitor similar to that shown in FIG. 2, which is attached to the centralized monitoring room 11, is individually connected to each receiver 9 by a signal line 7, and similarly outputs a buzzer BZ to notify that the container 2 has reached an abnormal temperature. Alarm by the corresponding container 2
Is displayed on the alarm lamp PL. FIG. 1 shows one warehouse 8, and each warehouse or the like for storing the container 2 before and after shipping has similar facilities.

[0013]

As described above, according to the present invention, when an abnormality occurs in any one of the containers and the normality determination signal is not sent to the alarm monitor, the alarm device is activated to operate the container at the central monitoring place. Since an abnormality is warned, there is no need to go to the container storage location and monitor it, and it is possible to reliably manage the occurrence of abnormal temperature and malfunctions related to its detection. Also, the transmitter
Since a normality judgment signal is transmitted by wireless such as infrared rays,
No problems such as disconnection as well as poor connection
No. Furthermore, above the top of the container is usually other luggage, etc.
Is an empty space where is not placed,
The normal judgment signal transmitted from the transmitter is not interrupted.
The receiver cannot reliably receive this normal judgment signal.
It is possible, and luggage etc. contacts or collides with the transmitter
Such a situation can be avoided, and damage to the transmitter can be prevented.
