[0041] Figure 1 It is a schematic diagram of the freight yard container number identification device, positioning device and system of the first embodiment of the present invention.

[0042] Refer to Figure 1 , the freight yard container number identification device, positioning device and system of this embodiment include a container number identification device 1, a container positioning device 2, a server 3, a container weighing device 4 and an angle detection device 5. Among them, the server 3 can be divided into a lower computer 31 and an upper computer 32. Specifically, the lower computer 31 can be a control device such as a PLC, a single-chip microcomputer or an FPGA, and the upper computer 32 can be an industrial computer, a server, a server cluster (such as a data server, a communication server, a web server, etc.).

[0043] The container number recognition device 1 is installed on the container lifting equipment (the container lifting equipment can be a gantry crane, a quay crane or a reach crane, etc.). The container number recognition device 1 can obtain the driving signal of the server 3. The server 3 can drive the container number recognition device 1 to enter the recognition state. Optionally, the system also includes a container number tracking device, which is configured to track the container number sprayed on the container. According to internationally accepted rules, the container number should be sprayed on the front, back, left, right and top five surfaces of the container, and there is a check code and a box type code at the end of the container number. The container number sprayed on the container refers to the spray mark sprayed on the five surfaces of the container. By setting the container number tracking device, the accuracy of the container number recognition device 1 in obtaining the container number can be improved. For example, a container number tracking device can be installed on the hanger of the container lifting equipment (for example, a reach crane), and the tracking device can generate a flag signal. The container number recognition device 1 can track the flag signal, so that the container number recognition device 1 can accurately capture the container number, thereby improving the accuracy of the container number recognized by the container number recognition device 1. The container number refers to a combination of numbers and letters, and can be expressed in the container number recognition device 1 and the server 3 in the form of text or character string.

[0044] In an optional manner, the container number identification device 1 can use radio frequency identification (RFID) technology: specifically, an RFID reader can be installed on the right side of the cab of the container lifting equipment, and an RFID card can be installed on each container, and each RFID card stores the container number of the corresponding container. For example, when the container lifting equipment grabs the container, the RFID card on the right side of the cab of the container lifting equipment is within the reading range of the RFID reader, and the RFID reader and the RFID card achieve non-contact two-way data communication through wireless radio frequency to obtain the container number.

[0045] The container positioning device 2 is installed on the container lifting equipment. The container positioning device 2 can generate position information. Specifically, the container positioning device 2 can generate longitude, latitude and altitude information. The container positioning device 2 is connected to the server 3 for communication. Driven by the server 3, the container positioning device 2 stores the position information in the register of the server 3, and generates the first position information in the server 3.

[0046] The container weighing device 4 is installed on the container hoisting equipment and can obtain the weight of the container. The container weighing device 4 is communicatively connected to the server 3, and the server 3 can obtain corresponding signals according to the change in the mass of the container weighing device 4. For example, when the weight value of the container weighing device 4 suddenly changes from zero to several tons, the server 3 can identify the rising edge signal; similarly, when the weight of the container weighing device 4 changes from several tons to zero, the server 3 can identify the falling edge signal. In this embodiment, the server 3 obtains the position information of the container positioning device 2 according to the falling edge signal and stores the position information in the register of the server 3, generating the first position information in the server 3.

[0047] The angle detection device 5 is installed on the container hoisting equipment and is configured to obtain the boom elevation angle of the container. In this embodiment, the server 3 obtains the boom elevation angle according to the angle detection device 5. When the server 3 detects that the boom elevation angle reaches the preset value, the server 3 can drive the container number identification device 1 to obtain the container number.

[0048] The server 3 is configured to bind the first position information with the container number and generate the first data record. In this embodiment, a database is pre-installed on the server 3. The server 3 binds the obtained first position information and the container number and stores them in the pre-installed database, generating a data record corresponding to the container number and the first position information in the database.

[0049] Figure 2 It is a schematic diagram of the container number identification device according to the first embodiment of the present invention.

[0050] The container number identification device of this embodiment includes a fixing frame 11, a camera 12, and a light source 13.

[0051] The fixing frame 11 is used to fix the container number identification device. Preferably, the fixing frame 11 is fixedly connected to the container hoisting equipment. For example, the container number identification device can be fixed under the cab of the container hoisting equipment.

[0052] The camera 12 is configured to obtain the container number.

[0053] The light source 13 increases the illumination in response to weak ambient light. For example, at night or on a cloudy day when the light is weak, the light source 13 can increase the illumination of the environment. The light source can be an LED lamp.

[0054] Figure 3 and Figure 4 It is a schematic diagram of the working state of the container number identification device according to the first embodiment of the present invention.

[0055] Referring to Figure 3 and Figure 4, the container number recognition device 1 is installed on the right side of the cab of the container hoisting equipment 7, and the boom 71 on the container hoisting equipment 7 can grab the container 6. During the process of the boom 71 grabbing the container 6, the boom 71 can form an angle A with the ground. When the boom 71 forms an angle A with the ground, the container number recognition device 1 can be triggered and emit light 121. At this time, the container number recognition device 1 can recognize the painted container number 61 of the container 6 and send the container number to the server. Specifically, the container number recognition device is communicatively connected to the server and sends the container number to the lower computer.

[0056] Combined with Figure 1 , where the processing steps of the lower computer 31 are:

[0057] The server is configured to drive the container number recognition device to obtain the container number in response to the elevation angle obtained by the angle detection device reaching a predetermined value;

[0058] Specifically, the lower computer 31 obtains the elevation value of the angle detection device 5, the weight value of the container weighing device 4, and the position information of the container positioning device 2.

[0059] In an alternative implementation, an angle sensor can be used as the angle detection device 5 to obtain the angle (i.e., elevation angle) formed by the boom 71 with the ground under various working conditions through the angle detection device 5. And the angle value formed by the boom 71 with the ground under various working conditions obtained by the angle detection device 5 is connected to a conversion circuit of the lower computer 31, so that the lower computer 31 can obtain the angle value formed by the boom 71 with the ground under various working conditions.

[0060] A weighing sensor can be used as the container weighing device 4, and the signal line of the weighing sensor is connected to another conversion circuit of the lower computer 31, so that the lower computer 31 can obtain the weight value of the container. The lower computer 31 can also obtain the signal value of the weight change in a configurable manner. For example, according to the weighing sensor from no signal to obtaining a signal, the lower computer 31 can obtain a rising edge signal (corresponding to the boom 71 grabbing or loading the container 6); according to the weighing sensor from having a signal to no signal, the lower computer 31 can obtain a falling edge signal (corresponding to the boom 71 releasing the claw or unloading the container 6).

[0061] A GPS sensor can be used as the container positioning device 2, and the container positioning device 2 is installed on the boom 71. The longitude and latitude signals that the container positioning device 2 can locate are connected to another conversion circuit of the lower computer 31, so that the lower computer 31 can obtain the first position information of the container positioning device 2.

[0062] The lower computer 31 allocates registers for the above-obtained sensors, as shown in Table 1:

[0063] Register Name Corresponding Sensor Annotation A1 Angle Sensor Corresponding Angle Detection Device 5 A2 Weighing Sensor Corresponding Container Weighing Device 4 A3 GPS Sensor Corresponding Container Positioning Device 2 A5 Box Number Identification Device 1 Corresponding Box Number Identification Device 1

[0064] Table 1 Register Allocation

[0065] According to the register allocation in Table 1, add the following registers

[0066] A4, constant, angle preset value.

[0067] A6, used to receive the container number.

[0068] A7, used to receive the first position information.

[0069] The server is further configured to obtain the container number, convert it into a falling edge signal according to the mass change of the container weighing device, and in response to the falling edge signal being true, obtain the first position information of the container positioning device; bind the container number with the first position information, and generate a data record.

[0070] Among them, B1 and B2, according to the change of A2, B1 is a rising edge signal and B2 is a falling edge signal.

[0071] B3, drive the container number identification device 1

[0072] In an alternative implementation, it can be implemented by the following pseudocode:

[0073] {

[0074] S1: CMP(A1, A4) Compare whether the angle A1 formed by the jib 71 and the ground reaches the preset value A4

[0075] S2: IF CMP, THEN B3 If the preset value is reached, B3 is true, and at this time the container number identification device 1 is driven to start identifying and spraying the container number 61

[0076] S3: MOV(A5, A6) Write the container number into A6

[0077] S4: IF B2 THEN MOV(A3, A7) In response to the falling edge signal B2 being true (corresponding to the jib 71 releasing the claw or unloading the container 6), write the first position information of the container positioning device into the register A7 of the lower computer

[0078] }

[0079] After the above pseudocode is executed, on the communication port of the lower computer 31,

[0080] S5: SEND A6 A7 TO SERVER 2 Send the data of A6 and A7 to the upper computer 32. After the sending is successful,

[0081] S6: CLEAR A6A7. Clear A6 and A7. By clearing the register, the next container number can be identified.

[0082] By executing S1 - S6, in this embodiment, when the angle formed by the jib 71 and the ground reaches a preset value, the container number can be obtained. When the jib 71 releases the claw or unloads the container 6, the first position information of the container is obtained, and the container number and the first position information are sent to the host computer 32.

[0083] The server binds the container number and the first position information and generates a first data record.

[0084] Specifically, on the host computer 32, there is a pre - created database. In an optional implementation, the server receives A6 and A7 and generates a first data record. For example, a data record can be created through an instruction, store A6 under the field identifying the container number, and store A7 under the field identifying the container position (i.e., the first position). Among them, the first data record is used to identify that the position of the container is inside the freight yard.

[0085] By creating a data record through the host computer 32 and storing the container number and the container position (i.e., the first position) under the same data record, the defect of easy error in manual recording by the container management personnel is avoided.

[0086] Since the first position information is directly obtained through the container positioning device and the first position information is expressed by longitude, latitude and elevation, for various managers of the freight yard, the first position information expressed by longitude, latitude and elevation has poor readability. Optionally, the first position information can be further parsed into corresponding freight yard information. For example, the server (host computer 32) obtains the longitude and latitude information in the first position information according to the parsed first position information of the container positioning device, and converts the longitude and latitude information into plane position information and floor height information. Specifically, a map of the freight yard can be compiled in advance according to the longitude and latitude information, divide the freight yard area, rows and numbers on the map, and query the corresponding freight yard area, rows and numbers according to the longitude and latitude information. The height information of the container positioning device can also be obtained through the server, and the height information is converted into the floor height information of the container. The server stores the freight yard area, rows, numbers and floor height information in another field of the data record.

[0087] By converting the longitude and latitude information into freight yard area, rows, numbers and floor height information, when various managers of the freight yard query the database, they can obtain the freight yard area, rows, numbers and floor height corresponding to the container number according to the container number, and the readability is better.

[0088] Optionally, when the container is to leave the freight yard, the server generates a second data record of the target container in response to receiving the destination address of the target container. The second data record is used to identify that the location of the container is outside the freight yard (i.e., the second data record is used to identify the next destination of the container after it leaves the freight yard). In order to track the next destination of the container in the management work, the server generates a new data record, i.e., the second data record, after receiving the destination address of the target container. The second data record includes the target container model and the destination address.

[0089] Figure 5 is a schematic diagram of the freight yard container positioning and identification system according to the second embodiment of the present invention.

[0090] Refer to Figure 5 , the freight yard container positioning and identification system of this embodiment includes a box number identification device 1, a container positioning device 2, a server 3, and a container weighing device 4. The difference between the second embodiment of the present invention and the first embodiment is that the angle detection device is removed in the second embodiment of the present invention. In this embodiment, the server 3 obtains the quality mutation situation of the container weighing device 4 to drive the box number identification device 1 to obtain the container box number. Specifically, in this embodiment, the server 3 drives the box number identification device 1 to obtain the container box number according to the rising edge signal of the quality mutation of the container weighing device 4.

[0091] Figure 6 is a working schematic diagram of the box number identification device according to the second embodiment of the present invention.

[0092] Refer to Figure 6 , the box number identification device 1 of this embodiment is installed on the boom (i.e., the hanger) of the container lifting equipment (such as a reach stacker). The boom 71 on the container lifting equipment can grab or unload the container 6 through the grabbing part 72 of the hanger. The container weighing device 4 is arranged on the grabbing part 72 of the hanger. During the process of the grabbing part 72 of the hanger grabbing the container 6, the server 3 can obtain the corresponding signal according to the weight change situation of the container weighing device 4. For example, according to the change of the weight of the container weighing device 4 from zero to several tons, the server 3 can identify the rising edge signal; similarly, according to the weight change of the container weighing device 4 from several tons to zero, the server 3 can identify the falling edge signal. In this embodiment, the server 3 drives the box number identification device 1 to obtain the container box number according to the rising edge signal; the server 3 obtains the position information of the container positioning device 2 according to the falling edge signal.

[0093] The server 3 stores the position information in the register of the server 3, and generates the first position information in the server 3.

[0094] The server 3 is configured to bind the first location information with the container number and generate a first data record. In this embodiment, a database is pre-installed on the server 3. The server 3 binds the obtained first location information with the container number and stores them in the pre-installed database, generating a data record corresponding to the container number and the first location information in the database.

[0095] Combined with Figure 5 , where the processing steps of the slave computer 31 are as follows:

[0096] The server is configured to convert the weight change of the container weighing device into a rising edge signal. In response to the rising edge signal being true, it drives the box number recognition device to capture the container number.

[0097] The server is further configured to obtain the container number, and convert the weight change of the container weighing device into a falling edge signal. In response to the falling edge signal being true, it obtains the first location information of the container positioning device, binds the container number with the first location information, and generates a data record.

[0098] The register allocation in this embodiment is the same as that in the first embodiment.

[0099] In an alternative implementation, it can be achieved through the following pseudocode:

[0100] {

[0101] S1:IF B1,THEN B3 If B1 is true, when B1 is true, the grasping part 72 successfully grasps the container 6. At this time, the box number recognition device 1 is driven to start recognizing the sprayed box number 61

[0102] S2:MOV(A5,A6) Write the container number into A6

[0103] S3:IF B2 THEN MOV(A3,A7) In response to the falling edge signal B2 being true (B2 being true corresponds to the crane arm 71 releasing the claw or unloading the container 6), write the first location information of the container positioning device into the register A7 of the slave computer

[0104] }

[0105] After the above pseudocode is executed, on the communication port of the slave computer 31,

[0106] S4:SEND A6 A7 TO SERVER32 Send the data of A6 and A7 to the host computer 32. After the sending is successful,

[0107] S5:CLEAR A6 A7 Clear A6 and A7. By clearing the register, the next container number can be recognized.

[0108] In this embodiment, the server 3 detects the change in the weight value obtained by the container weighing device 4. The change in weight from non - existent to existent is the rising edge. The server 3 drives the container number identification module 1 to obtain the container number in response to the rising edge. When the gripper of the crane arm 71 releases the grip or unloads the container 6, the server 3 generates a falling - edge signal in response to the change in weight from existent to non - existent. The server 3 drives the container positioning device 2 to obtain the first position information of the container according to the falling - edge signal, and sends the container number and the first position information to the host computer 32.

[0109] Bind the container number to the first position information and generate a first data record. The method of binding and the method of generating the data record are the same as those in the first embodiment of the present invention and will not be repeated here.

[0110] In this embodiment, the server detects the change in the weight value obtained by the container weighing device. The change in the weight value from non - existent to existent is the rising edge. The server responds to the rising edge and drives the container number identification module to obtain the container number. When the gripper of the crane arm releases the grip or unloads the container, the server responds to the change in the weight value from existent to non - existent and generates a falling - edge signal. The server drives the container positioning device to obtain the first position information of the container according to the falling - edge signal, and sends the container number and the first position information to the host computer. The server binds the container number to the first position information and generates a first data record. Thus, the defect of easy error in manual entry by management personnel is avoided. When the container yard container number identification device, positioning device and system of the present invention use a reach stacker (i.e., a kind of container lifting equipment) to load or unload containers in the container yard, the container number is identified by the container number identification device, and the container positioning device at the moment when the container is stored in the container yard is driven to store the first position information of the container storage in the server. At the server side, the first position information is bound to the container number and a data record is generated. The data record is stored in the container management of the container yard. The container yard management personnel can conveniently query, manage and allocate containers by querying the data record.

[0111] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
