Abstract

PURPOSE:To reject read of the number of a body to be detected by operator's or owner's will by emitting light from a light receiving element and recognizing a read reject signal or disturbance to reject the read. CONSTITUTION:The read of a bar code is selectively rejected by the will of a read rejector like an operator or an owner. In the case of read reject, a read reject bar code 6A in the same position as the bar code or in the position close to the bar code is read in the same manner as a bar code 6B of the body to be detected, or the reject signal of a read reject signal light emitting body 16 is detected by a light receiving element 9 to recognize it by a data code computer 13 that the read of the body to be detected is rejected, or a disturbance light emitting body 17 is operated and disturbance light is superposed on the reflected light of the bar code to make the bar code undecodable.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a logistics management system, and particularly to a traffic management system in which people and goods move together.

(Prior art) Automatic recognition technology has recently developed, including barcodes, data carriers, machine vision, and OCR.

Magnetic stripe and voice recognition have been put into practical use.

However, all of these target objects, and if a person exists at the same time as the object, automatic recognition similar to that of the object is not acceptable from the standpoint of privacy, human rights, and confidentiality protection, but this person or the owner wishes to do so. It is clear that this would bring about significant social benefits, such as highway tolls, parking fees, and traffic control. Furthermore, if an attempt is made to manage the movement of all objects to be detected passing through a detection location, the amount of processing will be enormous, there will be a lot of economic waste, and the processing speed will be slow, making it difficult to put this into practical use.

Furthermore, with the barcode system, it is difficult to detect when the object to be detected is far from the light receiving element, and it is difficult to recognize when the position of the object to be detected changes variously with respect to the light receiving element. However, if the barcode system device can be used in this case as well, it will be economical and there is a strong possibility of realization.

(Problem II to be Solved by the Invention) In order to overcome the problems of the prior art as described above, the present invention provides an automatic recognition system that can refuse to read the detected object number etc. at the will of the driver or owner. First thing to do
The purpose of A second object of the present invention is to provide an accurate and efficient automatic recognition system for a detected object. A third object of the present invention is to provide a traffic management system that uses the main parts of the barcode system to detect objects that are difficult to detect.

(Means and effects for solving the problems) The present invention is constructed as follows. As shown in Figure 1.

1) A bar code in which a light beam 2 emitted by a laser tube 1 is irradiated onto a bar code, the intensity of the reflected light is detected by a light receiving element 9 through a filter 8, and the digital signal 12 is converted into a digital signal 12, which is then converted into a character by a data code computer 13. The code system is characterized in that light is emitted from the barcode section mounted on the object to be detected 5 or its vicinity, and passes through the filter 8 in front of the light receiving element θ, and the reading is rejected as a reading rejection signal or disturbance.

The type of barcode of the object to be detected used in the present invention, the method of printing, defacing, and attaching the barcode, and the method of reading the barcode are not particularly limited (although known methods and devices may be used). A feature of the present invention is that the light that is not nullified by the filter in front of the light receiving element is emitted from the signal generating light emitter 16 to serve as a read refusal signal, or the disturbance generating light emitter 17 is emitted as a disturbance to the bar code to generate a bar code. The purpose is to prevent the reader from reading the information, and preferably to inform the person who refuses to read that the information cannot be read.This display to the person who refuses to read is to notify the person who refuses to read that the management is not carried out against the will of the person who refuses to read. be.

An embodiment of the present invention is shown in 9. For example, as shown in FIG. Surface reading refusal barcode 6A and object barcode 6
B is scanned, and the strength of the reflected light 7 is detected by a light receiving element 9 through a filter (disturbance light removal film) 8 and amplified as an analog signal 10, and then converted into a digital signal 1 by an A/D converter 11.
2, the data code computer 13 performs a code check and character conversion, and sends this data to the terminal control computer 14.

If necessary, connect the host computer 16 to this 9
Necessary administrative processing 1 such as charge calculation and receipt issuance is performed on either computer 14 or 15. In this case, to exclude barcode 6A that cannot be read, it is necessary to override this part so that it does not send information. 9) Operate so that the reflected light does not face the light receiving element. The easiest and most reliable read refusal signal is to send a read refusal signal from the signal emitting light emitter 16 of the detected object 5, or to emit light from the disturbance light emitter 17. It is determined by the data code computer 13 whether or not there is a reading refusal signal. This data code combination tool 13 follows the flow shown in FIG.

If a reading refusal signal is detected or cannot be read, the results can be shown to the person who refuses reading by voice or display, and the main issues in implementing the system, such as privacy, human rights, and confidentiality protection issues, can be resolved by mutual agreement. Since this is a matter of concern, it will be resolved.

The read refusal signal and disturbance light are superimposed on the intensity of the laser reflected light that scanned the barcode, and are detected by the light receiving element through a filter (disturbance light removal film), amplified as an analog signal, and processed by the A/D conversion circuit. As a digital signal,
The data code computer performs a code check and character conversion, but the translation becomes impossible due to the reading refusal signal, and the reading is refused or an error is displayed and the data is erased and the process ends.

In the present invention, a person who refuses to read a barcode, such as a driver or an owner, chooses to refuse to read the barcode. For example, reading refusal can be achieved by reading the reading refusal barcode 6A located at the same position as the barcode or in the vicinity thereof in the same way as the object barcode 6B in FIG. Either the data code computer recognizes that the object is a detected object that cannot be read, or activates a disturbance light emitter to superimpose disturbance light on the reflected light of the barcode, making it impossible to decipher it. There are various methods of disturbance generator depending on the type of light receiving element and sensitivity.

The cheapest and easiest method is to pass light through a filter.

In other words, it emits light with a wavelength close to the wavelength of the laser light used here. And do the best data processing systems include refuse-to-read barcodes?

Alternatively, if a rejection signal is detected, the data can be automatically deleted. In this system, for example, a data code computer,
If necessary, the terminal computer determines the presence or absence of a reading refusal code or wavelength light indicating reading refusal, as shown in Figure i2, and if it is ``present (T)'', it displays and erases the data. , If "None (F)", normal processing is performed and output.

When a light source is used as the reading rejection signal, a dedicated light receiving element having a wavelength band matching that of this signal may be used to simplify the processing operation.

By configuring the present invention as described above, it is possible to not only read the detected object but also refuse to read it according to the driver's or owner's will, and privacy, human rights, and confidentiality can be protected.

2) The present invention also provides a method in which a barcode is irradiated with a light beam 2 emitted by a laser tube l, and the strength of the reflected light is detected by a light receiving element 9 through a filter 8 to generate a digital signal 12. In a barcode system that performs character conversion, light that passes through a filter 8 in front of a light-receiving element 9 is emitted from a barcode section attached to a detected object 5 or its vicinity to generate a priority processing signal, and the object that emits this priority processing signal is The detection object 5 is an operation management system characterized in that the detection time, detection location, and detection object number are input into a computer, and this data can be outputted by the contractor's computer.

In the present invention, for items that the driver or owner desires priority processing among many logistics, a priority processing request signal is sent from the signal emitting light emitting body 1B attached to the barcode section attached to the detected object 6 or in the vicinity thereof. It emits light that passes through a filter in front of the light receiving element. Detected object 5 that emits this priority processing signal
is the detection time.

This operation management system is characterized in that the detection location and detected object number are input into the computer preferentially over other items, and this data can be output by the contractor's computer. The main parts of the device and system for this purpose can be the same as those described in section 1).

3) The present invention also includes: In an automatic recognition system that detects the intensity of light with a light receiving element through a filter, converts it into a digital signal, and converts it into a character using a data code computer, the light that passes through the filter in front of the light receiving element is converted into two levels of flashing light, long and short, to detect the detected object. Light is emitted from the signal emitting light emitting body 16, and the detected object that emits this signal inputs the detection time, detection location, and detected object number into the computer, and this data is output from the subscriber's combination 1-evening output. This is a traffic management system characterized by being configured to enable In other words, at the will of the driver or owner, the light that passes through the filter in front of the light-receiving element is emitted from the detected object as two levels of flashing light, long and short, and the detected object that emits this signal is determined by the detection time, detection location, The system is configured such that the subject number is input into the computer and this data can be output by the contractor's computer. In this case, since light is emitted from the object to be detected, detection is easy and there are few errors.The main parts of the apparatus and system in this case can be those described in section 1) or 2).

In the case of the system described in items 1) to 3) above, if the object to be detected is a car, a light emitting element array is attached to the side, side protector, bumper, etc., and a bar code is formed by this. However, the barcode can also be read by the light receiving element through a filter that selectively transmits the wavelength of the light emitting element. This can also be used as a reading refusal signal.

In addition, if the object to be detected is equipped with a light emitter that emits a bar code or blinking signal at approximately the same position from the ground, and the light-receiving element is installed at this height, the received light intensity will be high, reducing misreading. For example, in a passenger car, if a bar code is attached to the side protector (side protection band of a passenger car), the heights from the ground will be almost the same, and power supply wiring and attachment will be easy. The advantage of having a side molding part is that barcodes and light emission signals can be automatically detected as the object to be detected moves forward, without the need to wave a laser beam. Also, if it is in the front or rear position, the bumper position is good.

In addition, the barcode is drawn with a corrupted material that can be distinguished by infrared or ultraviolet light, and is used as a secret code to preserve the beauty of the object to be detected.

This can also be read by irradiating it with infrared laser light or ultraviolet laser light, and in this case, the
It can also be displayed on roots and trunks.

This operation management system can of course be applied to all types of logistics management that involve human intervention, and can also be used as a logistics system that respects the intentions of the owner or manager of things, even in fully automated cases where two people are not involved. can.

(Effects of the Invention) According to the present invention, it is possible to provide an automatic recognition system that can refuse to read the test specimen number etc. according to the driver's or owner's will. Furthermore, the present invention enables an accurate and efficient automatic recognition system for a detected object. Furthermore, according to the present invention, it is possible to provide a traffic management system that detects objects to be detected using the main parts of the barcode system. It is also clear that an operation management system that respects human rights, confidentiality, and will will become possible, and that significant economic benefits can be enjoyed.
