Description

  For example, when an abnormal situation such as a large impact applied to a package is detected, the present invention identifies the cause of the situation by recording the surrounding environment transportation environment where the package is placed, and improves the quality of logistics. The present invention relates to a method and system for inspection.

In the transportation industry, there is a desire to improve the quality of logistics by preventing damage accidents such as “striking”, “breaking and rubbing”, etc. that occur due to the rough handling of transported goods and the application of strong impacts. doing. In particular, it is required to grasp the situation in which a damage accident has occurred, identify the cause, and use it to improve the quality of logistics. There is also a desire to identify the party in the event of a damage accident.
Conventionally, an impact detection device having an impact sensor is attached to a package, and the impact value is recorded, and an alarm is issued when the impact value exceeds a predetermined magnitude. There has been known a system that guarantees no impact (see Patent Document 1). In such a system, although it is possible to identify the occurrence of an impact value of a predetermined magnitude or more, it is impossible to grasp the situation in which the occurrence of the impact value occurred, and it is not possible to identify the cause could not.
Further, a system has been known in which a waveform collection sensor, a GPS system, and a CCD camera are installed in a transportation vehicle, and by these, the soundness of the package is always confirmed in both directions in real time (see Patent Document 2). ). However, this system is not intended to specify the cause of the impact or the like of the package, but merely monitors the package in the transport vehicle.

This setting item is recorded in the data recording unit 18 of the data recorder 10. Thereafter, the data recorder 10 is installed in the package of the package. Normally, a dummy package is prepared and installed inside the package so that it is not known to the persons involved in the transportation.

2. Transport environment data recording by data recorder The sensor unit 16 of the data recorder 10 measures transport environment data. The measured transportation environment data is sent to the data processing unit 17 for determination of the warning condition and also sent to the data recording unit 18 for recording. The data recording unit 18 of the data recorder 10 receives and records transportation environment data from the sensor unit 16. For example, transportation environment data may be recorded continuously when the power of the data recorder is on, or may be recorded intermittently, for example, every 5 minutes, and conforms to warning conditions. Then, it is good also as what records only for the predetermined period before and behind determined.

3. Determination of Warning Conditions by Data Recorder When the data processing unit 17 of the data recorder 10 accepts the transportation environment data, it determines whether or not the warning conditions recorded in the data recording unit 18 match the received transportation environment data. I do.
For example, when the warning condition is an acceleration (impact magnitude) threshold, a temperature threshold, or a humidity threshold, the data processing unit 17 uses the accelerometer 161 and the temperature / hygrometer 163 to measure acceleration data and temperature. It is determined whether the data and humidity data exceed a threshold set as a warning condition.
For example, when the warning condition is an address and a time zone, the data processing unit 17 indicates that the position data measured by the GPS receiver 162 and the clock timer 164 and the time (elapsed time from the start of measurement) data are warnings. It is determined whether or not the position and time (elapsed time from the start of measurement) set as conditions are met.
If the data processing unit 17 of the data recorder 10 determines that the transportation environment data meets the warning conditions as a result of the determination processing, the server computer 30 sends a warning signal and the corresponding transportation environment data to the server computer 30 that an abnormal situation has occurred in the package. Send to. The transportation environment data transmitted together with the warning signal includes at least position data and time (elapsed time from the start of measurement) data where the data determined to meet the warning condition is measured. In addition, the transportation environment data transmitted together with the warning signal includes data at the moment when data for which a predetermined determination result is obtained is measured. For example, it is assumed that the data for which a predetermined determination result is obtained is one minute before and after the measurement.

The data processing unit 32 refers to the position data included in the transportation environment data corresponding to the warning signal, and performs a process of specifying the position of the package when the data determined to meet the warning condition is measured (step) S110). At the same time, a process for specifying the time when the data determined to meet the warning condition is measured is performed.
The data processing unit 32 of the server computer 30 refers to the installation position data recorded in the database 34, and selects the cameras 20 installed in the vicinity of the position of the package identified in the previous process from the plurality of cameras 20. A process for specifying is performed (step S120).
When the camera 20 is specified by the data processing unit 32, the camera control unit 33 of the server computer 30 transmits a control signal to the specified camera 20 (step S130). This control signal may include information specifying the time when the data determined to meet the warning condition is measured. Further, a plurality of cameras 20 to which the control signal is transmitted may be provided.
