Technical Field

The invention relates to the field of automated logistics design, in particular to the field of vehicle management.

Background

With the development of mechanical manufacturing automation and intelligent control technology, automation elements in modern plant logistics are increasing. For example, in the conventional technology, the dispatching of materials in each station in a factory building often depends on manual carrying or manual carrying by using vehicles such as a forklift, and the like, so that the efficiency is low, and the manual strength is high. The transfer of material is now accomplished using an automated logistics system.

For example, chinese patent publication No. CN201710106862.6 discloses a logistics transportation system, which includes an inbound structure, a guide rail, and an outbound structure. Goods are carried on the carrier and are conveyed on the conveying track, and automatic logistics conveying is achieved.

However, as the production scale is enlarged, the transportation path of the goods becomes longer, the time on the track increases, and the number of carriers transported on the track at the same time also increases, which causes difficulty in managing the carriers.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.

Embodiment 1, a vehicle monitoring system and a monitoring method thereof, as shown in fig. 1 and 2, include a vehicle. The physical form of the carriers differs in different logistics transportation systems. As in garment production systems, the carrier is often a hanger system. In a supermarket goods conveying system, the carrier can be a loading basket or a loading frame. The carrier is used for loading goods to be transported.

The number of the carriers is often multiple, and in a large and mature logistics conveying system, the number of the carriers is large, and the conveying distance is long. Firstly, each carrier is provided with an electronic tag, and the implementation form of the electronic tag is not limited, for example, RFID, two-dimensional code, barcode, etc. are used. In the following, RFID is used as an example, and ID information is stored in the RFID of each vehicle, and the ID information is unique, that is, the ID information of each vehicle is different.

The vehicle monitoring system also comprises a reader for reading an electronic tag, such as an RFID scanner, on the vehicle. Similarly, the reader is provided with a plurality of readers which are arranged at different positions of the whole logistics conveying line. Can be installed on a stand frame on the standing ground and also can be installed on a conveying track. The number and spacing of the readers can be individually adjusted according to the specific scale and required precision of the logistics delivery system.

The vehicle monitoring system comprises a control terminal, wherein the control terminal can be a PC (personal computer), and control software is installed on the PC. The control terminal comprises a storage module. The storage module stores a mapping table which reflects the actual installation positions of different readers in a workplace, the mapping table can be counted manually by an operation manager, and a positioning device can be additionally arranged on the reader to automatically generate position information input.

After the preparation work is completed, the logistics conveying system starts to operate, and a plurality of carriers are conveyed on the conveying line and scanned by the reader. If the reader a scans the carrier a, the ID information 0001 is read. The A reader sends the information to the control terminal, and the reader is in communication connection with the control terminal and can be wired or wireless. After the control terminal receives the communication signal, the position information of the A number reader is called out from the mapping table, so that the current specific position of the first carrier can be obtained and reflected on an output device such as a display screen, and convenience is provided for real-time monitoring of an operator.

In addition, because the carriers pass through the plurality of readers in sequence when being conveyed on the conveying line, the system can check the actual running track of a certain carrier according to the positions of the readers passing by the system.

In actual use, due to the reasons of large conveying pressure, large number of carriers and the like, the carriers are blocked and even fall off from the track. In the present application, since the vehicle itself does not have power, the vehicle is often mounted on a track and transported along with the movement of the track, and the traveling speed of the vehicle is the speed of the track movement. The conveying speed of the track is often known, measurable and constant during the actual conveying process. The system can judge the abnormal condition by calculating the time of the carrier passing through two designated readers.

Specifically, two readers, namely reader a and reader B, can be arranged on a certain section of track, and the time for the vehicle to pass through the section of track under normal conditions is measured to be 30 seconds by the system according to the distance between the two readers and the track conveying speed. The specific time value can be determined by the operator in a self-defined way. When each carrier passes through the reader A and is scanned, the timing module starts timing, and the timing is stopped until the carrier is scanned by the reader B, and the time is recorded as T.

When T is within this time threshold, e.g. 30 seconds, it is determined that the transport is normal. When T exceeds the threshold, i.e., exceeds 30 seconds, the system may determine that the track segment is in a transport congestion state. When other adjacent carriers pass through the mold in normal time and a timing value cannot be obtained for a certain carrier all the time, the mold is likely to fall off, and a manager can be warned in the modes of alarming, lighting and the like.

In the present application, the recording, timing, and warning judgment of the control terminal described above can be implemented by software programming, the software programming and the code of the function are prior art, and can be implemented by a person skilled in the art, which is not described and limited in detail.
