[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides acceleration and vibration data in the traveling direction of the transportation vehicle and in the direction perpendicular to the transportation vehicle (both in the vertical direction). At least one sensor built-in type wireless transmitter that measures and wirelessly transmits is received, acceleration and vibration data are received from the sensor built-in type wireless transmitter, and a warning is given to the driver when each exceeds a predetermined threshold Is output.
[0008]
According to the present invention, the driver can check the state of the load during transportation, and therefore can prevent damage to the load and collapse of the load by preventing vibrations from being repeatedly applied to the load. . The threshold determination may be executed by a computer of the operation management center connected to the transport vehicle via a wireless communication network.

In addition, although the power source 43 is a small and compact one using the vibration power generation element developed by the applicant of the present application, a solar cell, a normal dry battery, or a secondary battery may be incorporated. Moreover, it is good also as the power supply 43 of the type which receives a microwave from the outside and generates electric power. Incidentally, if a vibration power generation element is used for the power source 43, it is not necessary to replace the battery or charge it at all, and it is not necessary to give special energy such as microwaves from the outside. The handling of module 4 is very easy.

[0027]
Here, the acceleration excess determination is first performed by comparing the measured acceleration data with the threshold value α (S73). If the measured acceleration exceeds the threshold value α as a result of the determination, a warning is issued to the driver to alert him to driving (S75).
If the acceleration is within the threshold value α, the vibration threshold value β is further compared with the measurement data to make a vibration excess determination (S74). As a result of the determination, if the measured acceleration exceeds the threshold β, a warning is issued to the driver to alert the driver (S75), and if not, the process returns to S71 and subsequent steps.

Subsequently, the sensor network modules 4a, 4b, 4c, 4d, 4e, and 4f attached to the cargo bed 2 and the luggage 3 transmit measured acceleration and vibration data as status responses to the previous polling (S82). These measurement data are taken in via the input unit A61 in the base station module 6, and are compared with a predetermined threshold value by the acceleration / vibration excess determination unit 65 and the acceleration / vibration deviation value excess determination unit 65a.
[0033]
Here, the acceleration / vibration excess determination unit 65 first performs an acceleration excess determination by comparing the measured acceleration data with the threshold value α (S83). Here, if the measured acceleration exceeds the threshold value α, a warning is given to the driver to call attention to the driving (S86). The vibration excess determination is performed by comparing with the measurement data (S84).
[0034]
Here, if the measured vibration data exceeds the threshold value β, a warning is issued to the driver to alert the driver to driving (S86), and if it is within the threshold value β, the acceleration / vibration deviation value excess determination is made. The unit 65a is activated to determine whether the acceleration / vibration deviation value is exceeded.
The acceleration / vibration deviation value excess determination unit 5a calculates a deviation value for each of acceleration and vibration data measured by the sensor network modules 4a, 4b, 4c, 4d, 4e, and 4f attached to the loading platform 2 and the luggage 3. Then, acceleration / vibration deviation value excess determination is performed by comparison with a predefined threshold value (deviation threshold value) γ (S85). Here, if the measured and calculated deviation values of the acceleration and vibration data exceed the deviation threshold value γ, a warning is given to the driver to alert the driver to driving (S86). Return to processing.
[0035]
According to the second embodiment, acceleration and vibration during transportation are detected, and when the acceleration and vibration data exceed the threshold values α and β, or the deviation value between the acceleration and vibration data on the loading platform side and the load side is the threshold value γ. If the load exceeds the limit (when the load 3 is moving more than a predetermined amount independently of the loading platform 2), a warning is issued to the driver during transportation, so damage and collapse of the load can be prevented more reliably. be able to.

In this case, since the base station module 6 receives the results of the acceleration / vibration excess determination and the acceleration / vibration deviation value excess determination from the operation management center 8 and issues a warning to the driver, the load is reduced. .
In FIG. 6, reference numeral 8 denotes an operation management center computer, which includes a communication unit 81, an input unit 82, an output unit 83, an acceleration / vibration excess determination and acceleration / vibration deviation value excess determination unit 84, a monitor 85, and a microphone 86.

The order of the polling issuance follows the control of the sensor network module data transmission order control unit 64.
[0046]
Subsequently, each sensor network module 4a, 4b, 4c, 4d, 4e, 4f transmits the measured acceleration and vibration data as a status response to the previous polling (S92). It is taken in via the input part A61 of the module 6. The base station module 6 amplifies the measurement data by the signal amplification unit 65b, and then transmits the measurement data to the computer 8 of the operation management center via the wireless communication network 7 via the input unit B67 and the communication unit 68 (S93).
[0047]
The computer 8 of the operation management center receives the measurement data by the communication unit 81 (S94), takes it in through the input unit 82, and supplies it to the acceleration / vibration excess determination and acceleration / vibration deviation value excess determination unit 84.
First, the acceleration / vibration excess determination and acceleration / vibration deviation value excess determination unit 84 performs an acceleration excess determination by comparing the measured acceleration data with the threshold value α (S95). Here, if the measured acceleration exceeds the threshold α, a warning signal is transmitted to the base station module 6 via the output unit 83 and the communication unit 81 in order to issue a warning to the driver (S98).

A deviation value is calculated for each of the above and acceleration / vibration deviation value excess determination is performed by comparison with a predefined deviation threshold γ (S97). Here, when the measured and calculated deviation values of the acceleration and vibration data exceed the deviation threshold value γ, a warning is given to the driver to alert the driver to driving (S98).

Therefore, it is possible to prevent damage and collapse of the luggage. Furthermore, by managing the history of acceleration and vibration data during transportation, it is possible to present transportation history information when delivering a package to the recipient. That is, it is possible to prove that no load was applied to the package during transportation. Incidentally, the operation management center may issue a certificate with the operation management center as a third party or public organization.

However, the sensor network module that monitors only acceleration and the sensor network module that monitors only vibration. May be used in combination. That is, a single-function sensor network module may be used in combination. In addition, when monitoring acceleration and vibration data regardless of whether it is a single function or multiple functions, a warning may be issued when any one of the data exceeds a threshold value (appeals to any of the five senses). A warning may be issued when both data exceed a threshold value. Similarly, for example, when monitoring acceleration in the X, Y, and Z directions, a warning may be issued when data in only the X direction exceeds a threshold value, or data in any two directions or all A warning may be issued when the direction data exceeds a threshold value.
