Description

Technical Field

[0001] The present invention relates to the technical field of containers, and more particularly to a container electronic ventilator and a container having the same, which adopt advanced technologies in the fields of machinery, electronics, Internet of Things, etc. Background Art

[0002] As the main carrier tool for modern logistics transportation, containers play an irreplaceable and important role in modern logistics transportation fields such as road transportation, water transportation (inland river, sea transportation), railway transportation, and multimodal transportation. Currently, 95% of global international freight is completed by containers, and the total global international sea container volume is 40 million TEU. In 2014, the global container throughput reached 623 million TEU, and the container trade volume reached 160 million TEU. Multimodal transportation can give full play to the overall advantages and combined efficiency of various transportation modes, providing seamless door-to-door services for shippers, and representing the development direction of integrated transportation. Accelerating the promotion of multimodal transportation development in China is not only an important way to improve logistics efficiency, reduce logistics costs, and promote structural energy conservation and emission reduction in integrated transportation, but also the fundamental requirement for deepening the reform and development of transportation and promoting economic transformation and upgrading.

[0003] Currently in China, whether it is the container industry itself or the logistics industry, the degree of informatization is relatively low. To improve the intelligent level of containers, many solutions have been proposed by domestic and foreign experts and scholars, but most of them are external and additional, and few corresponding intelligent transformations are carried out on the structure of the container itself, so as to realize the acquisition of the corresponding state of the container, making the container itself have intelligent characteristics. The characteristics of the container itself are that it is constructed of metal materials and is restricted by a series of international and domestic standard systems. There are many restrictions on the intelligent transformation based on the corresponding structure. Therefore, at present, it is very rare to carry out intelligent transformation on the structure of the container itself. In terms of the intelligent transformation of the structure of the container itself, the intelligent transformation of the container ventilator has become a direction of concern.

[0004] Therefore, there is a need to provide a container electronic ventilator to at least partially solve the above problems. Summary of the Invention

[0043] In the following description, numerous specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without one or more of these details. In other instances, some well-known technical features are not described in order to avoid confusion with the embodiments of the present invention.

[0044] To thoroughly understand the embodiments of the present invention, detailed structures will be presented in the following description. Obviously, the implementation of the embodiments of the present invention is not limited to the special details familiar to those skilled in the art.

[0045] According to one aspect of the present invention, an intelligent container electronic ventilator 200 is provided. The container electronic ventilator 200 mainly includes a ventilator housing 210 and an integrated component 220 disposed in a cavity 216 formed in the ventilator housing 210. Among them, the integrated component 220 and the ventilator housing 210 are formed as a whole, so as to facilitate their overall installation onto the container 100 at one time. Thereby, the installation difficulty and installation cost of the container electronic ventilator 200 are reduced. Each component of the container electronic ventilator 200 will be described in detail below with reference to the accompanying drawings.

[0046] As Figures 4 - 6 shown, in the illustrated embodiment, the ventilator housing 210 is generally trapezoidal and has a cavity 216 formed therein. Specifically, the ventilator housing 210 mainly includes a bottom plate 211, a top plate 212, and four side plates 214 connected between the bottom plate 211 and the top plate 212. Among them, the top plate 212 and the bottom plate 211 are disposed on different horizontal planes, and an opening is provided at the middle position of the bottom plate 211. The projections of the side plates 214 and the top plate 212 in the vertical direction coincide with the opening of the bottom plate 211. Thus, the inner surfaces of the top plate 212 and the four side plates 214 together form the cavity 216 of the ventilator housing 210. When the container electronic ventilator 200 is installed onto the container 100, the integrated component 220 (which will be described in detail below) is embedded between the box body plate of the container 100 and the ventilator housing 210.

[0047] Optionally, at least one of the side plates 214 connected in the width direction between the bottom plate 211 and the top plate 212 is inclined, and a plurality of holes 215 are arranged on at least one inclined side plate 214. In one embodiment of the present invention, the plurality of holes 215 are regularly arranged on the side plate 214. In another embodiment of the present invention, the plurality of holes 215 are irregularly arranged on the side plate 214. Thus, when the container electronic ventilator 200 is installed onto the container 100 (please refer to Figure 1 and Figure 2 ), the exchange of gases inside and outside the box can be realized through the plurality of holes 215 arranged on the side plate 214 of the container electronic ventilator 200.

[0048] Further optionally, a baffle 217 extending towards the cavity 216 is provided on the inner surface of the top plate 212. The number of baffles 217 can be set to one or more, and the extension lengths of the baffles 217 in the cavity 216 can be set to be the same or different. For example, in the illustrated embodiment, three baffles 217 with inconsistent lengths extend into the cavity 216 at one end of the top plate 212 near the side plate 214 provided with a plurality of holes 215. By providing the baffles 217, the installation position of the integrated component 220 in the cavity 216 can be further defined. At the same time, when the container electronic ventilator 200 is installed on the container 100, the plurality of holes 215 on the side plate 214 can be completely exposed in the ventilation holes (not shown) on the container 100. Those skilled in the art can understand that the ventilator housing 210 of the container electronic ventilator 200 is not limited to the above specific embodiments, and it can be set in any shape suitable for installing the integrated component 220.

[0049] According to the design of the container electronic ventilator 200 of the present invention, the structure is simple, which is convenient for maintenance and replacement. By hiding the integrated component 220 in the ventilator housing 210, the pollution and artificial damage of the integrated component 220 during use are avoided. The container electronic ventilator 200 can meet the use requirements under harsh natural environments such as high and low temperatures and rain, and can maintain the original ventilation performance of the container electronic ventilator 200 without changing the structure and appearance of the container.

[0050] The integrated component 220 is arranged in the cavity 216 formed in the ventilator housing 210. Further, as Figure 7 shown, the integrated component 220 mainly includes a central processing unit 221, a storage unit 222, a communication unit 223, a positioning unit 224 and a power supply unit 227. Each unit can be electrically connected and / or electromagnetically connected to each other. Among them, the central processing unit 221 controls the communication unit 223 and the positioning unit 224, so that when the container electronic ventilator 200 is installed on the container 100, the monitoring platform can remotely monitor the position information of the container 100. Each unit in the integrated component 220 will be described in detail below.

[0051] The central processing unit 221 is used to implement data exchange between units and process the data. The central processing unit 221 can select one of ARM, single-chip microcomputer, DSP, and FPGA, and whether to load an operating system can be selected according to specific chips and development requirements. In addition, the central processing unit 221 can store or delete data in the storage unit 222 (which will be described in detail below). The container electronic ventilator 200 can have a data encryption mechanism so that the data of the monitored container 100 is transmitted using the encryption mechanism. Further, the central processing unit 221 can receive instructions from the monitoring platform (i.e., the monitoring terminal of the integrated component 220 in the container electronic ventilator 200).

[0052] The communication unit 223 is connected to the central processing unit 221 and can be used to communicate with the monitoring platform. Specifically, in order to enable the container electronic ventilator 200 to perform remote or short-range communication transmission of monitoring data according to different usage scenarios, the communication unit 223 includes a far-field communication unit for communicating the container 100 with the monitoring platform and a near-field communication unit for performing point-to-point communication between the container 100 and the monitoring platform (such as a reading and writing device). Optionally, a reflector (not shown) is further provided inside the ventilator housing 210 to enhance the wireless signal transmission intensity of the container electronic ventilator 200. Those skilled in the art can understand that the box board of the container 100 can also be used as a reflector. Further, the monitoring platform is correspondingly provided with a middleware (not shown) for parsing the received encrypted data.

[0053] The far-field communication unit includes a satellite communication unit and / or a cellular network communication unit. Specifically, the far-field communication unit of the container electronic ventilator according to the present invention may be a cellular network communication unit. The cellular network communication unit may include a cellular network communication module and an antenna (not shown). Optionally, the cellular network communication module includes an LPWA (Low Power Wide Area technology, such as NB-IOT) communication module. Among them, using the LPWA (Low Power Wide Area technology, such as NB-IOT) communication module for communication is the main far-field communication method of the container electronic ventilator 100 according to the present invention. The satellite communication unit may include a satellite communication module and an antenna (not shown). Optionally, the satellite communication module selects a low-earth orbit satellite communication module. Further, the far-field communication of the container electronic ventilator 200 according to the present invention can be further enhanced through the fusion communication of the satellite communication unit / cellular network communication unit. The central processing unit 221 can issue a switching instruction for autonomous switching between the far-field communication methods of satellite communication and cellular network communication according to the instruction received from the monitoring platform for switching the long-distance communication method or the information obtained after processing the data of the sensors (to be described in detail below). Specifically, low-earth orbit satellite communication is used at sea or in remote and desolate areas, and LPWA (Low Power Wide Area technology, such as NB-IOT) communication is used in areas covered by narrowband mobile communication networks. The antenna (not shown) can be integrally designed or separately designed with the container electronic ventilator 200.

[0054] In an embodiment of the present invention, the low-earth orbit satellite communication unit is a standardized communication unit, which has a standard air interface and a data transmission interface. The low-earth orbit satellite communication unit can realize data docking with an external controller through a standard serial communication interface and can communicate with a low-earth orbit satellite through a standard and open air interface. Optionally, the uplink bandwidth of the communication channel of the low-earth orbit satellite communication unit is 10KHz, and the downlink bandwidth is 25KHz.

[0055] The near-field communication unit includes near-field communication modules such as RFID, LORA, ZIGBEE, WIFI, etc. and an antenna. Optionally, the near-field communication unit can use the method of low-frequency wake-up high-frequency communication to communicate with the monitoring platform at a short distance. Further optionally, the low-frequency wake-up frequency uses 125kHZ communication, and the high-frequency communication uses 433MHz / 2.45GHz communication. This enables the container electronic ventilator 200 to have a low-frequency wake-up function to achieve long-term dormancy and ultra-low power standby of the intelligent terminal.

[0056] The storage unit 222 is connected to the central processing unit 221, which is capable of storing or deleting data in the storage unit. Specifically, the storage unit 222 can store the relevant data collected and processed by the central processing unit 221, the positioning unit 224, the communication unit 223, the power supply unit 227, and other units (such as the sensor unit 226 to be described later) of the container electronic ventilator 200 for a fixed period of time.

[0057] When the central processing unit 221 receives a signal to delete data in the storage unit 222 or when the data storage duration reaches or exceeds the storage capacity, it can delete the data inside the storage unit 222. Further, when the data storage duration in the storage unit 222 reaches or exceeds the storage capacity, the data inside the storage unit 222 is deleted in a first-in, first-out manner. Furthermore, in the absence of a communication network, the collected and processed data is temporarily stored in the storage unit 222, and after the network is restored, the historical stored data can be output from the storage unit 222.

[0058] The positioning unit 224 is connected to the central processing unit 221 and is used to locate the position of the container 100. The positioning unit 224 can include GPS satellite positioning, Beidou satellite positioning, or Beidou satellite / GPS satellite integrated positioning. Optionally, GPS satellites are used for positioning in areas not covered by Beidou satellites, and Beidou satellites or Beidou satellite / GPS satellite dual-mode integrated positioning are used in areas covered by Beidou satellites. Optionally, the positioning unit 224 can also include ground-based augmentation positioning, which includes various positioning methods such as cellular base station positioning, WIFI positioning, RFID positioning, or LORA positioning. Thus, the container 100 equipped with the container electronic ventilator 200 can be visible globally.

[0059] The power supply unit 227 includes a power interface, a power management unit, and a power storage unit. Optionally, the power supply unit can also include self-generating devices, which can be solar power generating devices, vibration power generating devices, or wind power generating devices. Specifically, the power management unit includes a lithium battery and a solar panel, and provides an interface connected to the battery. Further optionally, the integrated component 220 has a battery remaining capacity monitoring function to be able to replenish the power in a timely manner.

[0060] The integrated component 220 includes a voltage conversion circuit and / or a power control circuit. Among them, the voltage conversion circuit can convert the power supply voltage in the circuit to provide different levels of power supply voltage for each unit in the integrated component 220 (such as the central processing unit 221, the communication unit 223, etc.). The power control circuit has a sleep state and a working state. The power control circuit provides power for each unit in the working state.

[0061] The voltage conversion circuit can provide multiple groups of power outputs according to the power supply requirements of each part of the circuit in the container electronic ventilator 200. Specifically, the multi-mode low-earth orbit satellite positioning and communication terminal is powered by a built-in 3.6V lithium battery 61. According to the different working requirements of each unit, the power supply voltage of the circuit system can be divided into 3 levels: 3.3V, 4V, and 12V. Among them, the 3.6V lithium battery 61 is boosted to 12V through the DC / DC boost chip LM2700 for the OG2 satellite unit to work. The 3.6V lithium battery 61 is regulated to 3.3V through the LDO voltage regulator chip XC6215 for use by units such as the GPS / Beidou unit 31 and / or the acceleration sensor 71 in the container electronic ventilator 200. The 3.6V lithium battery 61 can be boosted to 4.0V through a boost circuit for use by the GSM / GPRS unit.

[0062] In order to further save the power of the container electronic ventilator 200, the power-on or power-off of the circuit can be controlled through a power control circuit, so as to accurately control the working states of each unit in the integrated component 220. Specifically, the integrated component 220 further includes a timer (not shown). Under normal circumstances, the entire circuit system is in a low-power sleep state. When the integrated component 220 is in the working state (such as sending positioning information and sensor data to the monitoring platform), the timer can automatically wake up the central processing unit 221, so that the central processing unit 221 controls the power control circuit to switch from the sleep state to the working state, that is, to provide power for the corresponding units through the power control circuit. When the integrated component finishes working, the central processing unit 221 controls the power control circuit to switch from the working state to the sleep state through the corresponding IO control pins, so that the entire circuit system enters the low-power sleep mode again. The above entire process circulates between the working state and the sleep state of the container electronic ventilator 200.

[0063] According to the power supply method of the power supply unit 227 of the present invention, the power supply unit 227 can meet the demand for long-term power supply of the container electronic ventilator 200. For example, when the communication unit 223 sends data to the monitoring platform on average every 2 hours, the battery life of the power supply unit 227 can reach more than 3 years.

[0064] While retaining its ventilation function, the container electronic ventilator 200 according to the present invention can also be used to intelligently monitor the position information of the container 100 over a large range remotely and proximally, and process, temporarily store, and transmit the monitored position information.

[0065] Furthermore, for the container electronic ventilator 200 according to the present invention, the integrated component 220 may further include a sensor unit 226. Specifically, the sensor unit 226 may include an acceleration sensor. This acceleration sensor is used to detect the motion state of the container 100 on which the container electronic ventilator 200 is installed. The central processing unit 221 determines the motion states such as the movement, stillness, and impact of the container 100 by processing the information collected by the acceleration sensor, thereby reducing the number of device communications and further reducing the power consumption of the circuit system. Optionally, the acceleration sensor 71 may be, for example, the acceleration sensor 71 of LIS3DH of STMicroelectronics. This acceleration sensor 71 adopts an ultra-low power consumption design, has the ability to detect three-axis acceleration, a working voltage of 3.3V, an average current of 1mA, and a static power consumption as low as 2uA. Further optionally, the acceleration sensor 71 has two communication interfaces, SPI and IIC, and uses the IIC interface to communicate with the central processing unit 221 chip in the circuit.

[0066] Further optionally, the sensor unit 226 may further include an in-built sensor disposed in the cavity 216 of the ventilator housing 210 and an external sensor disposed outside the cavity 216. Specifically, the in-built sensor includes one or several of a temperature sensor, a gas sensor, a barometric pressure sensor, and an anti-disassembly sensor. Among them, the temperature sensor can monitor the temperature condition inside the container 100; the gas sensor can monitor the gas condition inside the container 100; the barometric pressure sensor can monitor the barometric pressure condition inside the container 100; the anti-disassembly sensor can monitor the installation state of the container electronic ventilator 200. The external sensor includes a container door switch state detection sensor and / or a container empty / full state detection sensor to detect the box state and cargo state of the container 100, thereby meeting people's other monitoring requirements for the container 100. It should be noted that the types of sensors installed in the container electronic ventilator 200 are not limited to the above embodiments and may be any other suitable sensors, such as a humidity sensor.

[0067] The container door opening / closing state detection sensor can be a capacitance, resistance or inductance sensor, a travel switch sensor, a Hall sensor, a strain resistance sensor, an ultrasonic sensor, an infrared sensor, etc. The empty / full container state detection sensor can be a strain induction sensor, an ultrasonic sensor, an infrared sensor or a travel switch sensor, etc. Further optionally, the container electronic ventilator 200 further includes an interface unit 225. The sensor unit 226 is connected to an external sensor disposed outside the container electronic ventilator 200 through the interface unit 225, so that the container electronic ventilator 200 interacts with the external sensor. For example, the data detected by the external sensor 225 can be obtained through the central processing unit 221 of the container electronic ventilator 200. Specifically, the interface unit 225 can be connected to the external sensor in a wired or wireless connection manner.

[0068] Furthermore, the container electronic ventilator 200 can provide an expansion interface, integrate multiple communication protocols, and be able to identify and adapt to the communication protocols of external devices. At the same time, information such as the state information, environmental information, cargo information, and work tasks of the container 100 is collected and transmitted to the monitoring platform for big data analysis and decision-making processing.

[0069] Thus, it can be seen that the container electronic ventilator 200 provided according to the present invention can perform intelligent large-scale remote and short-range monitoring on the container 100 to be monitored. For example, it can simultaneously perform positioning, detect the filling condition, opening / closing state, motion state, internal temperature of the container, and remotely and short-range monitor various information such as the external environment of the container, and process, temporarily store and transmit the monitored information, greatly improving the intelligent level of the container 100.

[0070] Furthermore, the integrated component 220 of the container electronic ventilator 200 according to the present invention can include satellite communication technology, GPS satellite navigation / Beidou satellite navigation dual-mode positioning technology, solar cell technology, micro-embedded computing technology, ultra-low power consumption technology, etc., and can provide global coverage, low cost (manufacturing cost: less than $40; operating cost: when sending data every 2 hours, the cost is controlled within $1 per month), low power consumption, anti-interference positioning, data collection and remote communication capabilities for the container 100 installed with the container electronic ventilator 200, and realize low-cost transmission of the data monitored by the container electronic ventilator 200 in more than 200 countries around the world.

[0071] According to another aspect of the present invention, there is provided a container 100, which at least includes one container electronic ventilator 200 according to the present invention. Further, the box body plate of the container 100 is a corrugated plate, and the container electronic ventilator 200 is disposed in the recess of the corrugated plate (such as Figure 3As shown, the structure of the container 100 and the stacking between containers 100 can be affected as little as possible.

[0072] The box body plates of the container 100 include side plates 110 arranged on the sides of the container, end plates 120 arranged at the ends of the container, and top plates 130 arranged on the top of the container. Specifically, one or more container electronic ventilators 200 are installed in the recessed portions of the box body plates of the container 100. As Figures 1 - 3 shown, in an embodiment of the present invention, one container electronic ventilator 200 is provided at the upper end of each of the two side plates 110 of the container 100. In another embodiment of the present invention, the container electronic ventilator 200 is arranged on the end plate 120 of the container 100. In still another embodiment of the present invention, the container electronic ventilator 200 is arranged on the top plate 130 of the container 100.

[0073] Furthermore, since the external structure of the container electronic ventilator 200 according to the present invention is generally the same as that of an ordinary container ventilator, the container electronic ventilator 200 and an ordinary container ventilator can be installed on the same container 100 at the same time. That is to say, the intelligent container electronic ventilator 200 provided with the integrated component 220 can be installed on the same container 100 at the same time as an ordinary container ventilator that only has the ventilator housing 210 in the container electronic ventilator 200.

[0074] Thus, by mixing and installing the container electronic ventilator 200 and a plurality of ordinary container ventilators at different positions on the box body plates of the container 100, the container electronic ventilator 200 provided with the integrated component 220 can be hidden in the ordinary container ventilators, reducing the possibility of the container electronic ventilator 200 being damaged or stolen by people.

[0075] Even further, ventilation holes (not shown) are provided in the recessed portions of the box body plates of the container 100. When the container electronic ventilator 200 is installed, the container electronic ventilator 200 covers the ventilation holes on the outside of the box body. As Figure 3 shown, the container electronic ventilator 200 is configured to cover the ventilation holes in the recessed portions of the corrugated plates. Thus, the container 100 can conduct gas circulation inside and outside the box through a plurality of holes 215 provided on the side plates 214, and at the same time, the integrated component 220 provided in the cavity 216 can remotely monitor the status information, environmental information, cargo information, and work task information of the container 100.

[0076] The present invention has been described by the above embodiments. However, it should be understood that the above embodiments are only for illustrative and explanatory purposes, and are not intended to limit the present invention to the scope of the described embodiments. Those skilled in the art can understand that according to the teachings of the present invention, more variations and modifications can be made, and these variations and modifications all fall within the scope of protection required by the present invention.
