Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to specific embodiments of the present invention and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The water area governed by the Yangtze river three gorges navigation management bureau is positioned at the junction of the upper and middle stream of the Yangtze river and is transversely spanned with two world-scale large-scale water conservancy hubs of the three gorges and Ge Zhou dams. Considering that the navigation environment is greatly changed along with the construction of the three gorges hydraulic junction engineering, the number of the over-dam ships is increased, the passing-gate traffic is greatly increased, and the navigation order and the transportation pattern are greatly changed. In the aspect of ship passing, a good passing order can be established by utilizing a ship accurate positioning means, and the ship passing efficiency is improved, so that the method is one of important links for promoting the stable development of the Yangtze river economic zone.

With the continuous development of information, communication and network technology and the continuous improvement of personalized requirements and service requirements, a first-generation terminal exposes a plurality of problems. For example: the ship positioning accuracy is low, signal drift exists, and the phenomenon that the ship walks on the shore often occurs on an electronic channel map; the individual ship owner has the action of going into the machine, in order to realize the purpose of inserting the priority pass-gate, dismantles GPS positioning terminal and arrives the pass-gate in advance and declares the position, utilizes false position information to declare the pass-gate plan, has seriously disturbed the pass-gate order.

The main mode of the three gorges voyage section passing ship safety inspection is that a security inspection personnel gets on the ship for inspection, and the main inspection content is information data such as ship personnel, crewman identity information, ship navigable certificates, voyage logs and the like. In addition, the above 2-4 terminals are installed on the vessels in the Yangtze river for shipping, so that not only is the economic burden increased for the crews due to the purchase of the terminals, but also the ship drivers are dazzling to the plurality of terminals. However, the data provided by the terminal are different, and the data uploaded by the terminal are also faced with different supervisor units, which is not beneficial to sharing and unifying the data. Therefore, there is a need for standardized deployment studies of ship lock terminals that provide a "one-to-one source" for the shipping authorities while also reducing the load on the shipper.

In order to improve the efficiency of ship passing through the locks of three gorges and Ge Zhou dams, the management and service level is further improved, a ship-shore (between a manager and a service object) real-time information interaction platform can be built by means of the multifunctional single Beidou intelligent terminal, a network-access ship user can pass through the multifunctional single Beidou shipborne intelligent terminal, a remote electronic reporting and scheduling system of ship passing through the locks is realized, automatic receiving and planning, issuing and the like of reporting information are realized, and traditional manual to-anchor reporting and 24-hour passing-through modes are thoroughly changed.

According to an embodiment of the invention, a ship passing control device is provided. Referring to fig. 1, a schematic diagram of an embodiment of the apparatus of the present invention is shown. The ship passing control device may include: the device comprises a main control unit, a positioning unit, a display unit and a verification unit. The main control unit, such as a main substrate, can be used for uniformly controlling the positioning unit, the display unit, the verification unit, the voice unit and the key unit. Positioning units such as AIS radio frequency boards. A display unit such as a display screen and/or a touch screen. And the verification unit is used for verifying the identity of the user, such as an identity verification module, a fingerprint verification module, a double camera and the like. A speech unit, such as a double horn. A key unit such as a plurality of keys and an indicator light.

Specifically, the positioning unit can be used for collecting the position information of the positioning unit and sending the collected position information to the main control unit so as to realize positioning of the ship position when the ship passes the gate and is declared.

Specifically, the verification unit may be used for collecting and verifying identity information of the crew member and performing identity verification according to the identity information of the crew member.

Specifically, the main control unit can be used for determining whether the positioning unit is removed in the current running route of the ship, verifying the identity of the crew based on the acquired identity information of the crew when the positioning unit is not removed in the current running route of the ship, generating a verification passing instruction after the verification passes, and controlling the ship passing based on the verification passing instruction, the ship position when the ship passes and control information input by a user; and generating a reminding message that the positioning unit is removed in the current running route of the ship under the condition that the positioning unit is removed in the current running route of the ship.

Therefore, through the cooperation setting of the main control unit, the positioning unit and the verification unit, whether the positioning unit is detached to carry out accurate detection when the ship passes the gate can be realized, and the safety control to the ship passes the gate is accurate and efficient.

Optionally, the main control unit determining whether the positioning unit is removed in the current driving route of the ship may include:

the first step: and under the condition that the antenna of the positioning unit is removed, acquiring the last piece of positioning information, namely the first positioning information, stored by the positioning unit under the condition that the antenna is removed.

More optionally, the obtaining, by the main control unit, the last piece of positioning information stored by the positioning unit under the condition of removing the antenna may include:

the main control unit can be used for determining whether the main power supply of the positioning unit cuts off signal access, namely determining whether the main power supply of the positioning unit is powered down.

For example: the main power supply is operated for 24 hours during the ship operation, and the condition that the main power supply is cut off from signal is generally two kinds: one is that the ship stops sailing or completes one transportation task, belonging to normal operation. The other is an artificial disassembling machine, such as a disassembling and positioning unit, which belongs to the illegal action.

The main control unit can be used for controlling the standby power supply of the positioning unit to start under the condition that the main power supply of the positioning unit is cut off.

For example: the function of the standby power supply is that when the main power supply is cut off, the normal operation of the positioning unit and the control unit such as the Beidou disassembly detection module is required to be ensured, and if the Beidou positioning data are continuously recorded and stored, the data are conveniently transmitted back to the supervision department after the terminal is electrified and in a networking mode. The standby power supply is a chargeable battery, can work independently after full charge and can run continuously for 2 months, and the equipment is charged after being electrified.

The main control unit may be further configured to determine whether an antenna signal of the positioning unit can be received.

For example: the antenna status signal needs to be detected in view of the fact that whether the ship side is illegal cannot be judged only by the fact that whether the main power supply is powered down. For example, the positioning antenna is not pulled out during normal operation, and only the dismounting device such as the dismounting positioning unit is required to pull out the antenna, because the antenna is already fixed on the ship and cannot be carried with the terminal. The antenna can be a long line extending from the cockpit to the top of the cockpit, and can be understood as a television which is watched before, and an antenna needs to be arranged outside for normal use. And the positioning unit can receive the Beidou satellite signals only by accessing the antenna if the Beidou positioning module is accessed, so that positioning analysis is performed. And an antenna signal data transmission interface is arranged in the Beidou positioning module, and if the data transmission interface can not receive information, the antenna is disassembled. If the interface normally receives the data transmitted by the antenna, the antenna is indicated to be accessed.

The main control unit is also specifically configured to determine that the antenna has been removed and save the last piece of positioning information of the positioning unit if the antenna signal of the positioning unit cannot be received. For example: and under the condition that the Beidou antenna is dismantled, storing the last piece of Beidou positioning data. Naturally, if the antenna signal of the positioning unit can be received, the acquisition of the first positioning information is ended.

Therefore, the last piece of positioning information stored after the positioning unit is powered down can be accurately stored by acquiring the last piece of positioning information stored by the positioning unit under the condition of removing the antenna, so that the position information of the positioning unit when the positioning unit is powered down can be accurately judged.

And, a second step of: and under the condition that the antenna of the positioning unit is re-accessed, acquiring the latest piece of positioning information acquired by the positioning unit under the condition that the antenna is re-accessed, namely second positioning information.

More optionally, the obtaining, by the main control unit, the latest piece of positioning information acquired by the positioning unit under the condition of re-accessing the antenna may include:

The main control unit is also specifically configured to determine that the antenna has been re-accessed if the antenna signal of the positioning unit can be received, and obtain the latest piece of positioning information of the positioning unit.

For example: under the condition that the Beidou antenna is re-connected, acquiring the latest piece of Beidou positioning data, judging whether the position change of the ship is abnormal, namely determining whether the positioning unit is removed in the current running route of the ship according to the first positioning information and the second positioning information.

Therefore, the latest piece of positioning information which is stored after the positioning unit is electrified again can be accurately stored by acquiring the latest piece of positioning information which is acquired by the positioning unit under the condition of re-accessing the antenna, so that the position information of the positioning unit when the positioning unit is electrified again can be accurately judged.

And a third step of: and determining whether the positioning unit is removed in the current running route of the ship according to the first positioning information and the second positioning information.

Therefore, whether the positioning unit is dismantled in the current running route or not is judged according to the last positioning information after the positioning unit is powered down and the latest positioning information after the positioning unit is powered up, so that accurate judgment on whether the positioning unit reports the brake off line or not is realized, the judgment accuracy is good, and the safety of controlling the brake report of the ship is improved.

Wherein, the first positioning information may include: first location information and first time information. The first time information may be a power-off time of the positioning unit. The second positioning information may include: second location information and second time information. The second time information may be a powering up time or a powering up time of the positioning unit.

More optionally, the main control unit determines whether the positioning unit is removed in the current driving route of the ship according to the first positioning information and the second positioning information, and may include:

The main control unit is also specifically used for determining the running time required by the ship to run from the first positioning information to the second positioning information according to the running speed of the ship in the current running route; and determining a time difference between the second time information and the first time information.

The main control unit is also specifically configured to determine whether the running time is greater than the time difference, and determine whether a difference between the running time and the time difference is greater than a set threshold.

The main control unit is also specifically configured to determine that the positioning unit is removed in the current travel route of the ship if the travel time is greater than the time difference and the difference between the travel time and the time difference is greater than a set threshold.

The main control unit may be further configured to determine that the positioning unit has not been removed in the current travel route of the ship if the travel time is less than the time difference, or if the travel time is greater than the time difference, but a difference between the travel time and the time difference is less than or equal to a set threshold.

For example: a ship route is Shanghai- > Yichang- > Chongqing, and when the ship runs to Yichang, a gate is required to be declared. The violation flow is that before the ship starts from the Shanghai, the equipment is powered off and taken out, a last Beidou position (last Beidou positioning data L1 and power-off time T1) is recorded and stored by a module after power off, at the moment, other people take high-speed rails to transport the equipment to Yichang to start reporting (the equipment and the ship are in one-to-one correspondence, one ship does not exist for a plurality of equipment), the reporting needs to be powered on, and at the moment, the position (latest Beidou positioning data L2 and power-on time T2) is recorded. The linear distance s of L1 and L2, the time difference T of T1 and T2, can be calculated. Normally, the ship running speed is relatively slow, 20-30km/h, and the time from the Shanghai running to Yichang running of one ship is relatively fixed, and can comprise the time of intermediate loading and unloading operation, transportation and the like, which is more than 10 days. However, if the iron is high, the time difference t is obviously reduced after 1 day. And when the power-off and the power-on offset distances are integrated, the smaller the time difference is, the more obvious the illegal sign is, the terminal disassembly warning information is pushed, and then the disassembly prevention detection flow is ended.

For example: calculation formula of ship violation probability

Wherein a represents: the distance from the starting point of the ship ascending route to the reporting point, b represents: the ship sailing theory uses time, s is in km, and t is in h.

Therefore, whether the positioning unit is detached in the current running route of the ship or not is determined according to the first positioning information and the second positioning information, whether the positioning unit is off-line gate reporting in the current running route of the ship or not can be accurately judged, and accordingly the safety of the ship gate reporting can be guaranteed.

Optionally, the main control unit may include: the device comprises a CPU module, a communication module and a storage module. The communication module and the storage module are respectively connected to the CPU module.

For example: the main control unit can be a main substrate. The main substrate may include: CPU module, WIFI module, 4G module, FLASH module, DRAM module etc.. The main substrate can be used for providing a system operation hardware environment by adopting an RK3399 industrial grade main board.

For example: the wireless communication module can be used for realizing the function module of data communication between the shipboard terminal and the system center, and the module can comprise a wireless communication transceiver, a communication network interface and a protocol. Such as a 4G communication module.

Therefore, the main control unit is formed by adopting the CPU module, the communication module, the storage module and the like, so that the structure is compact, and the data processing capability is high.

Alternatively, the verification unit may include: the system comprises an identity verification module, a fingerprint verification module and/or a double-camera acquisition module. For example: the remote security check function can provide various personnel verification modes based on face recognition, fingerprint recognition, identity card recognition and the like.

Specifically, the identity verification module can be used for collecting identity information input by a shipman. For example: the identity card verification module can be used for realizing crewman identity verification in a mode of brushing identity cards. The second-generation identity card information reading function requirements can include: the terminal should be able to read the information in the second generation resident identification card chip through the second generation resident identification card reader. The reading speed of the identity card is less than 1S.

Specifically, the fingerprint verification module can be used for collecting fingerprint information of a shipman. For example: the fingerprint verification module can be used for realizing crewman identity verification in a fingerprint scanning mode. The fingerprint image acquisition function requirements may include: the terminal can collect the fingerprint plane images of the left hand or the right hand thumb of the person through the fingerprint collector and compare the fingerprint plane images with the guide pattern characteristics in the identity card. The fingerprint image quality evaluation function is supported, the area of the effective area of the fingerprint is not less than 40% of the area of the image, the left-right deviation between the center position of the effective area of the fingerprint and the center of the image is not more than 14 pixels, and the up-down deviation between the center position of the effective area of the fingerprint and the center of the image is not more than 20 pixels. The fingerprint lines should be clear and continuous. The fingerprint reading speed is less than 1S.

Specifically, the dual-camera acquisition module can be used for acquiring facial information and/or iris information of a crew member. For example: the binocular camera can be used for realizing crewman identity verification in a face recognition mode and providing a video communication function. The binocular camera face image acquisition and storage functional requirements can include: the terminal is provided with a binocular camera, a visible light color camera and an infrared camera. The terminal can automatically shoot the front photos of the personnel, and can comprise automatic face positioning, quality judgment of the photos of the personnel, extraction of a face template, automatic separation of the photos of the plurality of persons who follow the photos and preferential treatment of the photos of the personnel before the photos. The face image is stored in a local terminal or a platform server. The photo is collected as a visible color photo and an infrared black-and-white photo of the person.

Therefore, the authentication system can be convenient for authentication use in various requirements or various occasions by various authentication modes such as an identity authentication module, a fingerprint authentication module, a double-camera acquisition module and the like, and the authentication efficiency can be improved.

Alternatively, the positioning unit may include: a satellite positioning unit. The satellite positioning unit may include: AIS radio frequency board.

For example: the positioning unit adopts an AIS radio frequency board, so that data fusion of the AIS radio frequency board and the main substrate is realized, and the AIS radio frequency board is positioned in a single-mode double-frequency Beidou positioning chip. The AIS radio frequency board can provide AIS data acquisition and transmission functions.

For example: the satellite positioning unit may be used for providing positioning information by a module with satellite positioning function, and may include position information, speed information and time information, and the module may include a satellite positioning receiver and an internal interface and protocol. Such as a single Beidou chip, a Beidou antenna, an internal interface and a protocol, and an AIS board card, an AIS antenna, an internal interface and a protocol.

Therefore, by adopting the AIS radio frequency board, the data fusion of the AIS radio frequency board and the main substrate is realized, and the positioning accuracy is good.

The electronic river map is a special geographic information system, and some electronic river map generation and development systems mostly adopt platforms and adopt an offline storage mode. The inland electronic river map is a comprehensive information system platform which meets the requirements of inland navigation and management informatization by applying modern computer technology and information processing technology, the application range of the inland electronic river map is completed according to different actual requirements, and the inland electronic river map has a plurality of different requirements:

1) The electronic map has no unified international specification and standard, but can draw reference to the international standard of the electronic map to formulate information technology standards of different countries and regions, such as the determination of a development platform, a system interface and the like.

2) The database of the electronic river map is based on the measurement data of different navigation channels, is provided and updated by the navigation channel departments of each country, and is not generally opened to the outside.

3) The application of the electronic river map can be used as a paper navigation reference map for the inland navigation management department to carry out important means of ship dispatching, safety, accident analysis and operation besides being used as an inland navigation reference map.

Fig. 6 is a schematic view of a ship passing control flow according to an embodiment of the terminal of the present invention. As shown in fig. 6, in the scheme of the present invention, a ship passing control flow of a terminal, that is, a flow of an anti-disassembly detection method of a beidou positioning unit, may include:

and step 1, cutting off signal access of a main power supply.

For example: the Beidou chip has an ADC detection function, and compares the voltage difference between the main power supply and the standby battery to judge whether the main power supply is connected.

The main power supply is operated for 24 hours during operation of the vessel. The main power supply is cut off in two cases, namely, the ship stops sailing or completes one transportation task (belonging to normal operation). Secondly, the machine is disassembled manually (illegal action).

And 2, starting a standby power supply of the positioning unit.

And 3, detecting the antenna state. The detection antenna aims at: whether the ship side is illegal or not can not be judged only by the fact that whether the main power supply is powered down or not, and an antenna state signal needs to be detected. For example, the positioning antenna is not pulled out during normal operation, and only the dismounting device is required to pull out the antenna, because the antenna is already fixed on the ship and cannot be carried with the terminal. The antenna is a long wire extending from the cabin to the top of the cabin. It can be understood that a television which is watched before can be normally used only by putting an antenna outdoors.

The Beidou positioning module can receive Beidou satellite signals only by accessing an antenna, and then positioning analysis is carried out. And an antenna signal data transmission interface is arranged in the Beidou positioning module, and if the data transmission interface can not receive information, the antenna is disassembled. If the interface normally receives the data transmitted by the antenna, the antenna is indicated to be accessed.

The standby power supply has the function that when the main power supply is cut off, the normal operation of the Beidou disassembly detection module is required to be ensured (such as continuous recording and Beidou positioning data storage, and the data is convenient to return to the supervision department after the terminal is electrified and in networking operation). The standby power supply is a chargeable battery, can work independently after full charge and can run continuously for 2 months, and the equipment is charged after being electrified.

As shown in fig. 12, the terminal offline information obtaining manner may include: the ship power supply mode, the module battery power supply mode and the shore power supply mode can be selected for use.

Alternatively, in the on-board power supply mode, timing may be set such as recording UTC (i.e., world standard time) time, latitude and longitude, speed, and antenna status once every 3 minutes. The positioning result and the antenna status are recorded, whether or not the antenna is connected.

Optionally, in the module battery power supply mode, it is necessary to determine whether the antenna is connected; if the antenna is connected, the information such as UTC time, position, speed and antenna state is kept, and the sleep mode is also periodically entered once every 3 minutes, and data is stored once after awakening; if the antenna is not connected, the time-consuming mode is entered at intervals of 5 minutes.

Alternatively, in the on-shore power supply mode, LOG information (i.e., running time information) needs to be read, and then the data is erased. And judging whether the client violates rules or not according to the read information, the position, time and antenna state of the client report. It is also necessary to determine whether the antennas are connected; if the antenna is connected, NMEA information (namely standard format information formulated by marine electronic equipment) is required to be uploaded after the antenna is positioned, and non-positioned information is not uploaded; if the antenna is not connected, uploading NMEA information without a positioning mark, and alarming after analyzing by a server, and otherwise, not connecting the antenna.

Step 4, judging whether the Beidou antenna is dismantled? If yes, executing the step 5; otherwise, ending the anti-disassembly detection flow.

And 5, saving the last piece of Beidou positioning data.

Step 6, determine if the main power is on? If yes, executing the step 7; otherwise, step 8 is performed.

And 7, detecting the antenna state.

Step 8, judging whether the Beidou antenna is accessed? If yes, executing the step 9; otherwise, ending the anti-disassembly detection flow.

And 9, acquiring the latest Beidou positioning data.

Step 10, judging whether the ship position change is abnormal? If yes, executing the step 11; otherwise, ending the anti-disassembly detection flow.

For example: the course of a ship is Shanghai->Yichang-room toy>Chongqing, when the ship runs to Yichang, the ship needs to declare a pass gate. The violation flow is that before the ship starts from the Shanghai, the equipment is powered off and taken out, a last Beidou position (last Beidou positioning data L1 and power-off time T1) is recorded and stored by a module after power off, at the moment, other people take high-speed rails to transport the equipment to Yichang to start reporting (the equipment and the ship are in one-to-one correspondence, one ship does not exist for a plurality of equipment), the reporting needs to be powered on, and at the moment, the position (latest Beidou positioning data L2 and power-on time T2) is recorded. The linear distance s of L1 and L2, the time difference T of T1 and T2, can be calculated. Normally, the ship running speed is relatively slow, 20-30km/h, and the time from the Shanghai running to Yichang running of one ship is relatively fixed, including the time of intermediate loading and unloading operation, transportation and the like, is more than 10 days. However, if the iron is high, the time difference t is obviously reduced after 1 day. The deviation distance is integrated when power is off and power is on, and the smaller the time difference is, the more obvious the violation sign is. Calculation formula of ship violation probability

Wherein a represents: the distance from the starting point of the ship ascending route to the reporting point, b represents: the ship sailing theory uses time, s is in km, and t is in h. The violation probability is mainly used for analyzing and judging the judgment of the ship violation declaration, and a certain threshold value is required to be referred to.

And 11, pushing terminal disassembly warning information, and ending the disassembly prevention detection flow.
