In the present embodiment, the in-vehicle information output device 3 is specifically an LED smart voice screen. The in-vehicle information output device 3 is actively authenticated and connected to the management server 21 through a wireless network such as a 4G LTE (Long Term Evolution) communication network; the management server 21 identifies the in-vehicle information output apparatus 3 based on the reported registration information and performs centralized management. The in-vehicle information output apparatus 3 and the management server 21 are kept in active connection by a periodic heartbeat packet.
The embodiment also provides a control method of the container terminal truck-concentrating service and management system based on the Internet of things. Referring to fig. 2, the control method includes steps S01 to S05.
And S01, acquiring the PLC information of the bridge.
The service subsystem 1 receives operation instructions from the container terminal operation management system in real time and acquires field bridge PLC information. Specifically, a back-end main server 12 in the service subsystem 1 obtains an operation instruction and field bridge PLC information from the container terminal operation management system and the field bridge PLC through an interface server 13. The field bridge PLC information comprises the position of the trolley, the height of the lifting appliance and the locking and unlocking state of the lifting appliance.
S02, judging whether the lifting appliance is in a lowering state and the height is smaller than the first height according to the field bridge PLC information; if so, generating a first voice text representing the lowering of the lifting appliance; if not, step S03 is executed.
And the rear-end main server 12 judges whether the lifting appliance meets a first preset scene according to the acquired field bridge PLC information. In this embodiment, the first preset scenario is that the lifting appliance is in a lowering state and the height is less than 6 meters; the first height is 6 meters. If the lifting appliance accords with a first preset scene, a first voice text 'lifting appliance is lowered, please align' indicating that the lifting appliance is lowered is generated. If the spreader does not conform to the first preset scenario, go to step S03.
S03, judging whether the lifting appliance is in a lifting state and the height is greater than a second height according to the field bridge PLC information; if so, generating a second voice text representing lifting of the lifting appliance; if not, step S02 is executed.
And the rear-end main server 12 judges whether the lifting appliance accords with a second preset scene according to the acquired field bridge PLC information. In this embodiment, the second preset scenario is that the lifting tool is in a lifting state and the height is greater than 6 meters; the second height is 6 meters. And if the lifting appliance accords with a second preset scene, generating a second voice text 'lifting appliance lifting, please pay attention to safety' representing lifting appliance lifting.
The first height and the second height may be the same or different.
And S04, acquiring the trailer number of the container truck.
A truck refers to a truck, which may also be referred to as a trailer, that transports containers within a dock. Each card concentrator has a number, such as a license plate number, called a trailer number. There are various ways to obtain the trailer number, which may be obtained by the interface server 13 by reading the bridge command.
S05, judging whether the container truck is an inner container truck or an outer container truck according to the trailer number of the container truck; if the container truck is an inner container truck, the first voice text or the second voice text is sent to the vehicle-mounted information output equipment corresponding to the trailer number; and if the hub card is an external hub card, acquiring a corresponding intelligent terminal number according to the trailer number of the external hub card and sending the first voice text or the second voice text to the intelligent terminal corresponding to the intelligent terminal number.
The hub is divided into an inner hub and an outer hub. An inner hub is a hub inside a dock, where work is usually performed. An external hub refers to an external hub that may perform some part of the work at the terminal, such as entering the terminal to transport containers to the outside or returning containers to the terminal.
For the internal hub, the back-end main server 12 calls the management server 21 to send the first voice text or the second voice text to the in-vehicle information output device 3 corresponding to the trailer number, and the in-hub in-vehicle information output device outputs the first voice text or the second voice text in a voice form. Specifically, after the interface of the management server 21 acquires a new voice transmission or text display request, it sends information to the designated in-vehicle information output device 3 according to the called parameter.
For the external hub card, after the service subsystem 1 obtains the trailer number of the external hub card, the corresponding mobile phone number of the driver is found in the hub card service system through the trailer number pushing interface. In this embodiment, the intelligent terminal is a smart phone; the intelligent terminal number is a mobile phone number. Then, the back-end host server 12 calls the message server 22 to send the first voice text or the second voice text to the mobile phone corresponding to the mobile phone number, and the mobile phone outputs the first voice text or the second voice text in a voice form.
According to the above, the embodiment judges whether the lifting appliance is in a lowering state and the height is smaller than the first height according to the acquired field bridge PLC information, and if so, generates a first voice text indicating that the lifting appliance is lowered; or judging whether the lifting appliance is in a lifting state and the height is greater than the second height, and if so, generating a second voice text representing the lifting of the lifting appliance. And judging whether the hub is an inner hub or an outer hub according to the acquired trailer number. And then, sending the first voice text or the second voice text to the vehicle-mounted information output equipment 3 corresponding to the trailer number, or acquiring the mobile phone number of the external hub card through the trailer number and sending the first voice text or the second voice text to the intelligent terminal corresponding to the mobile phone number. The vehicle-mounted information output device 3 or the intelligent terminal may output the first voice text or the second voice text to remind the driver. So, this embodiment can prevent that interior truck and outer truck from pulling the crane hoist at the in-process of loading and unloading container operation, is favorable to the safety of pier loading and unloading business. Practice shows that the accident of collecting and pulling the lifting appliance does not occur since the system of the embodiment is on line.
And the container is unloaded by the shore bridge after the container is transported to the shore bridge by the container truck. The operation processing flow of the shore bridge will be described. Referring to fig. 4, reading the OCR (Optical character recognition) identification information of the bank-side intelligent tally system in real time to obtain the trailer number; reading PLC information of the shore bridge in real time to obtain the position of the trolley, the height of the lifting appliance and the locking and unlocking state of the lifting appliance; judging whether the lifting appliance is in a lifting state and the height is greater than a second height; if the lifting appliance accords with a second preset scene, a second voice text 'lifting appliance lifting, please note safety' representing lifting appliance lifting is generated; then, calling a voice pushing interface of the vehicle-mounted voice screen of the management server 21 to send the second voice text to the vehicle-mounted information output equipment corresponding to the trailer number; and recording a voice sending log for subsequent data analysis.
Referring to fig. 3, the in-vehicle information output apparatus 3 of the present embodiment includes a main control board 31, an LED display unit board 32, a communication unit board 33, a voice unit 34, and a microphone 35. After the LED smart voice screen as the in-vehicle information output device 3 receives the information from the management server 21, the main control board 31 of the device sends data to the LED display unit board 32 to display the information according to the received control command, or sends the data to the voice unit 34 to be analyzed and then performs voice broadcast through the integrated loudspeaker 35 such as a speaker. The communication unit board 33 is a 4G DTU (Data Transfer unit); the 4G DTU actively registers with the management server 21, establishes heartbeat connection, and receives data and voice text data from the management server 21; the 4GDTU sends the data from the management server 21 to the main control board 31 through a 232 serial port; the main control panel 31 sends the text information to the LED display unit panel 32 according to the communication protocol, and sends the voice information to the voice unit 34 for analysis and then outputs the voice information to the speaker for playing.
In order to receive the message, the intelligent terminal of the external container truck driver needs to access the container terminal truck service and management system based on the internet of things. An external card collector driver uses an uniform service platform (ePort) APP, inputs a mobile phone number and then logs in the ePort APP; after logging in, the mobile App pushing platform, such as SDK (software development Kit) of the Tencent homing pigeon, is automatically called to perform registration processing according to the mobile phone number. The push interface of the message server 22 will finally call the interface provided by the Tencent carrier pigeon to push the corresponding information, such as text information, to the intelligent terminal of the driver according to the intelligent terminal number. The ePort APP on the intelligent terminal can receive the pushed information through the SDK of the Tencent carrier pigeon and display the received text information in the message bar of the intelligent terminal; the intelligent terminal broadcasts the received Text information through a Text to speech (Text to speech) interface carried by an android or ios system; if the smart terminal is in a mute state at this time, the eportap will automatically turn on the sound and tune the sound to a specified value, such as a maximum value.
The control method of the present embodiment further includes recording a transmission log of the first voice text or the second voice text for management and data analysis.
After the container is loaded by the truck, the container is transported to a ship to load the container onto the ship. The lockpins on the containers need to be manually disassembled and assembled in the shore loading and unloading ship operation of the traditional container terminal. The lock pin is mainly used for ensuring the fastening of the container when the container is stacked on a ship. This may result in a secure safety risk for the container on the vessel if the wrong lock is installed. For this reason, the control method of the present embodiment further includes steps S06 to S011.
Step S06, receiving a job instruction from the container terminal operation management system.
Specifically, the interface server 13 may receive a work instruction from the container terminal operation management system for subsequent determination.
Step S07, if the operation command belongs to a ship operation command, generating lock pin information based on the size of the container and the position where the container is to be fixed on the ship. If the work order does not pertain to a vessel work order, such as vesseltype < > VSL, then no lockpin handling of the container is required.
If the fixed position is a position on the deck and a position on the first layer of the deck, generating information which does not need to be locked; if the fixed position is a position on the deck and is a position other than the first layer of the deck, corresponding deck pin information is generated.
If the fixed position is a position on the cabin and a position on a first layer of the cabin, generating information which does not need to be locked; if the fixed location is a location on the hold and is a location other than the hold leader, corresponding hold pin information is generated.
Referring to fig. 5, if the size of the container is a first size, specifically, less than or equal to 20 feet, it is determined whether the fixed position of the container is on the deck; if the fixed position of the container is on the deck, for example, if the type A is D, judging whether the fixed position is the first floor of the deck, if so, locking the container is not needed, and therefore, generating information which does not need to be locked; if the fixed position is not the first layer of the deck, acquiring a ship information definition table, determining the type of the lock pin according to a field (such as a field Stowtype) of the loading type and outputting corresponding deck lock pin information; specifically, if Stowtype is Russian, the locking pin information shows "M", otherwise the locking pin information shows "D". If the fixed position is a position on the hold and a position on the first floor of the hold, the container does not need to be locked, and therefore information that locking is not needed is generated; if the fixed position is the position on the cabin and is the position except the first layer of the cabin, the structure of the ship is obtained, whether the bin position corresponding to the current instruction can only contain 20-size containers is judged, if the bin position can only contain 20-size containers, the containers do not need to be locked, therefore, information which does not need to be locked is generated, and otherwise, the locking pin information displays 'H'.
Referring to fig. 6, if the size of the container is the second size, which is 40 feet in particular, it is determined whether the fixing position of the container is on the deck; if the fixed position of the container is on the deck, for example, type a is D, judging whether the fixed position is the first floor of the deck, if so, locking the container is not needed, and therefore, generating information that locking is not needed; if the fixed location is not the first floor of the deck, the latch information displays "DD". If the fixed position is the position on the cabin and the position on the first layer of the cabin, acquiring the structure of the ship, judging whether the bin position corresponding to the current instruction allows the installation of containers with the size of more than 40 feet, and if the installation of the containers with the size of more than 40 feet is allowed, locking the containers is not needed, so that information which does not need to be locked is generated; if the fixed position is a position on the cabin and a position other than the first floor of the cabin, the structure of the ship is acquired, whether or not the installation of 40 or more containers is allowed in the position corresponding to the current command is judged, and if the installation of 40 or more containers is allowed, the locking information is displayed as 'HH'.
Referring to fig. 7, if the size of the container is a third size, specifically, 45 feet or more, it is determined whether the fixing position of the container is on the deck; if the fixed position of the container is on the deck, for example, if the type A is D, judging whether the fixed position is the first floor of the deck, if so, locking the container is not needed, and therefore, generating information which does not need to be locked; if the fixed position is not the first layer of the deck, judging the size of the lower-layer container; if the size of the lower container is 45 or more feet, the locking pin information is displayed as "B5", otherwise, the locking pin information is displayed as "C5". If the fixed position is a position on the ship's hold, the container does not need to be locked, and therefore information that locking is not needed is generated.
And step S08, calculating the number of the trucks waiting for shipment.
If the operation instruction indicates mixed loading operation, namely the container is in a mixed loading fixed mode, finding out the instruction of the mixed loading operation consistent with the operation instruction; and traversing all instructions of mixed loading operation, finding out the planned hoisting times of the containers to be loaded vertically below the position on the ship, and taking the minimum value as the number of the containers to be loaded on the ship, thereby improving the operation efficiency.
If the loading operation is not mixed loading operation, finding out the planned hoisting times of the containers to be loaded vertically below the position on the ship corresponding to the operation instruction, and taking the planned hoisting times as the number of the containers to be loaded on the ship.
And step S09, acquiring information of the hoisting machine.
The crane of the wharf comprises a shore bridge and a gantry crane. These hoisting machines are responsible for hoisting containers on the container trucks to the vessel.
Information of the hoisting machine is available on the basis of the work orders received from the container terminal operation management system. But the information of the hoisting machinery needs to be content-converted for output.
Specifically, for the shore bridge, the shore bridge information is the shore bridge number, which may be QC04 through QC49, and thus may be sequentially displayed as Q04 through Q49 in digital coding.
For the door machine, the door machine information is the door machine number, which can be MQ51 to MQ55, and thus can be sequentially displayed as M51 to M55 according to the digital code.
For the convenience of distinguishing, the SKP bank equipment number is added with a letter S. For the shore bridge, if the numbers are SQC01 to SQC04, they may be displayed as S01 to S04 in order by digital coding; for the gantry crane, if the numbers are SMQ22, SMQ27 to SMQ29, they may be displayed as S22, S27 to S29 in order of numerical coding.
And step S010, calculating the working time. The working time refers to the time elapsed since the container terminal operation management system received the working order.
And S011, sending the locking pin information, the number of the shipment waiting collecting cards, the information of the hoisting machinery and the operation time as push contents to the vehicle-mounted information output equipment for output.
The back-end host server 12 converts the current push content according to the format required by the management server 21. The converted contents and the trailer number of the corresponding card album, such as an IMEI (international mobile equipment identity) number, are then pushed to the management server 21. The push content is transmitted to the in-vehicle information output apparatus by the management server 21, and is displayed in text by the in-vehicle information output apparatus with reference to fig. 8 to 13.
According to the method, the type of the lock pin matched with the shipping plan of the container transported by the container truck can be automatically obtained, and the lock pin type is visually displayed to the unlocking and locking worker through the LED display screen, so that the unlocking and locking worker unloads the lock according to the instruction. Can avoid dismouting lockpin operation to receive rain and fog weather influence, can promote the security of pier loading and unloading operation, can improve security, accuracy and the efficiency of harbor district operation.
Refer to fig. 8 to 13. The display of the detent information is explained. In the present embodiment, the in-vehicle information output device displays the lock pin information with two-digit characters; specifically, the locking pin information is displayed at the corresponding position according to the position of the container pressed on the container truck and the size of the container. If there is only one order, the container size is 20 feet, the container is pressed in front of or in the middle of the card, and the pin information is displayed in the first place, for example "H". If there is only one order, the container size is 20 feet, the container presses behind the card catch and the pin information is displayed in the second position, e.g. "H".
