Description

Car weight measuring system to use the car number recognizer

The present invention relates to a vehicle weighing system for measuring the weight of a vehicle, and more specifically, a vehicle using a vehicle number recognizer that integrates and manages metering information by recognizing vehicle number data transmitted from a carrier and a vehicle number recognized in a weighing room. It is about a weighing system.

In general, after measuring the weight of the incoming cargo vehicle and the weight of the cargo vehicle in the tolerance state to unload the cargo, the weight of the cargo is measured by the difference between the two measured values.

As shown in FIG. 1, a conventional vehicle weighing system includes a tag 10 for wirelessly transmitting information of a vehicle, a measuring device 20 for measuring a weight of a freight vehicle, a tag signal, and a weight of the vehicle. It is composed of a microcomputer 30 to be input, a processor computer 40 connected to the microcomputer 30 and responsible for the weighing process.

As shown in FIG. 2, the vehicle weighing system uses a tag 10 in which information of a freight vehicle is classified by code, as a radio transmitter. That is, the vehicle driver rotates the dial on the front of the tag box to match his freight code with his freight code previously input to the microcomputer 30, and then closes the tag box to the antenna 50 to tag 10 ) Transmits its own vehicle information wirelessly to the weighing room. The vehicle information data transmitted wirelessly is input to the microcomputer 30 of the metering room. When the microcomputer 30 recognizes the vehicle, the measurement device 20 is operated and vehicle measurement is performed. The measured result is stored in the processor computer 40.

The vehicle driver who has finished weighing at the weighbridge is unloaded and re-weighed. The processor computer 40 calculates the net weight of the cargo compared to the time of tolerance measurement and issues the slip 60. When the driver goes to the meter room where the ticket machine is installed and receives the document 60, the vehicle weighing is completed.

On the other hand, the monitoring room 70 is installed in the weighing room to monitor the entry state of the cargo vehicle, which allows the administrator to check the measurement state through the monitor 80 of the central management room.

However, the conventional vehicle weighing system as described above has the following problems.

First, the driver must operate the dial of the tag box in order to input his vehicle information. At this time, there is a problem that incorrect settlement is not performed when the vehicle information is incorrectly input due to the driver's mistake. That is, when the vehicle information is incorrectly input to the microcomputer 30 by a driver's mistake, the microcomputer 30 calculates the actual weight different from the actual weight based on the tolerance weight corresponding to the incorrectly input vehicle. This causes a lot of time and manpower to be corrected even if an abnormality is found in the process of measuring the tolerance after the cargo has been unloaded.

Second, freight vehicles need to weigh the actual weight before unloading and the tolerance weight after unloading separately, which requires a lot of weighing time and requires the installation of separate tolerance weighing stations.

Third, there is a cumbersome problem that the information is not shared between the carrier and the transport client, and the document 50 is issued after the measurement is completed and submitted to the freight carrier.

This means that the vehicle driver must move to the weighing room in which the document issuer is installed in order to receive the document 60, and must receive the received document 60 back to the carrier. Accordingly, if the receipt of the slip to the carrier is delayed or missing, the settlement result may not be identified or matched in real time between the carrier and the client.If the slip (60) is lost, it is reissued after confirmation. This is followed by various problems due to the slip 60.

The present invention has been made in consideration of the above-mentioned conventional problems, and prevents a wrong measurement caused by a wrong input of freight vehicle information by a driver, and the information sharing is made in real time between the carrier and the transport client while the weighing process is simplified. An object of the present invention is to provide a vehicle weighing system using a number recognizer.

The measuring device 100 is installed in the metering room. The weighing table 110 is placed at the bottom of the weighing room, and a weight sensor 120 for measuring the weight of the vehicle waiting on the weighing table 110 is installed at the bottom of the weighing table. In addition, the position sensor 130 is installed on the front and rear and side of the weighbridge 110 to detect the position of the vehicle, and the microcomputer 140 that stores the weight of the vehicle measured by the weight sensor 120 is It is provided. The microcomputer 140 transmits the weight of the vehicle measured to the main computer 300.

In addition, one side of the weighing room is provided with an electronic board (not shown) for informing the progress of the start / completion of the metering, the measurement results and the driver instructions. And the monitoring camera 320 which monitors the situation in a measurement room is provided. The surveillance camera 320 is connected to the monitor 330 installed in the central management room to inform the manager of the situation in the central management room.

The vehicle number recognizer 200 includes a digital video camera 210 for photographing a vehicle number and an optical character recognizer 220 connected to the digital video camera 210.

The digital video camera 210 is installed at a part where the license plate of the front or rear of the vehicle in the metering chamber is easily seen, and the photographed data is output to the optical character recognizer 220.

The optical character recognizer 220 analyzes the screen signal input from the digital video camera 210 and extracts the character to recognize the vehicle number. The vehicle number data is transmitted to the main computer 300.

The main computer 300 is installed in the central management room and is connected to the carriers online through the Internet. The main computer 300 receives and stores vehicle information from the carriers and transmits the measurement results to the corresponding carriers. It is also responsible for the management of all measured information.

Meanwhile, an alarm generator 310 that is connected to the main computer 300 and generates an alarm signal when it is confirmed by the main computer 300 that the vehicle information is not stored in advance or the vehicle to be weighed for the first time is detected. Can be.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the present invention made of the configuration as described above.

Carrier enters the information of the cargo, including the vehicle number of the cargo vehicle and information necessary for transportation before the carriage, and transmits the data to the main client 300 of the transport client via an online such as the Internet. The transmitted data is stored in the main computer 300.

When the freight vehicle moves over the weighbridge 110 in order to weigh the cargo weight, the weight sensors 120 installed around the weighbridge 110 check the correct position of the vehicle. If the vehicle is detected to be out of the correct position by the position sensor 130, an alarm signal sounds from the position sensor 130, and a message for instructing the driver to move the correct position on the electronic display is displayed.

When the driver moves the vehicle to the correct position according to the indication on the signboard, the vehicle number recognizer 200 recognizes the number of the vehicle. That is, the digital video camera 210 photographs the vehicle number, and the optical character recognizer 200 recognizes the vehicle number based on the video signal. The recognized vehicle number is transmitted to the main computer 300 of the central management room, the main computer 300 performs a vehicle authentication by searching for a matching vehicle number among the data received from the carrier. As such, when the freight vehicle is authenticated through the vehicle number recognizer 200, it is possible to prevent the miscalculation caused by the misoperation of the driver as in the related art.

When the vehicle number is authenticated by the main computer 300, vehicle measurement starts. However, if the vehicle number is not retrieved or the vehicle number is retrieved but the first vehicle to be weighed has not been weighed, the main computer 300 causes the alarm device 310 to output a warning message to the administrator, thereby causing the administrator to follow up. To take.

That is, if the vehicle number is not retrieved from the main computer 300, the manager can immediately handle the problem by receiving the information of the target vehicle from the transport company. After unloading, the process of measuring a separate tolerance weight is further performed to secure the tolerance weight of the vehicle to be weighed for the first time. Therefore, the vehicle can be weighed on the basis of the stored tolerance weight without having to measure the tolerance weight later.

Meanwhile, the weight of the weighed freight vehicle is stored in the microcomputer 140 of the weighing room, and these data are transmitted to the main computer 300. The main computer 300 calculates the weight of the cargo as the remaining weight minus the previously stored tolerance weight based on the data. According to the above method, since the tolerance weight is already stored in the main computer 300, a rapid weighing operation can be performed without measuring the tolerance weight separately as in the related art.

When the main computer 300 transmits the measurement results of the cargo online to the corresponding carrier, all the weighing operations are completed, and the cargo driver may unload the cargo and return to the carrier without subsequent procedures. Therefore, the process of issuing the document and receiving it and submitting it to the carrier is excluded, and problems related to the document occurring in this process can be solved at one time.

On the other hand, all the situations in the weighing room by the monitoring camera 320 installed in the weighing room is monitored through the monitor 330 of the central management room.

According to the vehicle weighing system using the vehicle number recognizer of the present invention configured as described above, since the vehicle number recognizer recognizes the freight vehicle, it is possible to prevent the error measurement by the driver misoperation.

In addition, since the tolerance weight is already stored in the main computer, the tolerance weight measurement process, which has been carried out after cargo unloading, is excluded as in the prior art, so that the weighing operation can proceed quickly, and it is necessary to install a plurality of measurement chambers to perform the tolerance weighing. As a result, facility costs for manpower and weighing are reduced.

In addition, since the information related to vehicle weighing is shared in real time between the freight carrier and the freight forwarding client, the process of issuing, receiving and accepting a slip as in the prior art is omitted, as well as weighing between the freight carrier and the freight forwarding client. Performance is aggregated in real time, and all problems arising from the documents are resolved at once.

Although the present invention has been illustrated and described in connection with specific embodiments, the present invention may be variously modified and changed without departing from the spirit or the field of the present invention provided by the following utility model registration claims. It should also be included in the scope of the present invention.
