In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

The utility model provides a credible safe satellite terminal equipment. The trusted security satellite terminal device may be connected to the bottom surface of the grooves of the corrugated plate of the side wall of the container and located outside the bottom surface of the grooves (outside the bottom surface of the grooves in the width direction of the container away from the center of the container). It will be appreciated that in embodiments not shown, trusted secure satellite terminal devices may also be connected to the end walls of the container. In this way, in the case of stacked containers, the containers do not block the trusted secure satellite terminal device from transmitting or receiving communication signals.

As shown in fig. 1-3, a trusted security satellite terminal device includes a housing assembly 110. The housing assembly 110 includes a housing 111 and a base 112. The housing 111 is configured in a substantially rectangular parallelepiped structure. The inner side face of the housing 111 (the side face of the housing 111 in the width direction of the container near the center of the container in the case where the trusted security satellite terminal device is connected to the side wall of the container) has an opening 113. The housing 111 is a plastic member. Thus, the weight of the housing 111 is small. Further, the housing 111 does not interfere with the later antenna arm assembly 120 to send out communication signals or receive communication signals outside the housing assembly 110.

The base 112 is a metal member. Thus, the strength of the base 112 is large, and the base 112 can firmly support the antenna arm assembly 120, the antenna circuit unit 130, the controller 140, and the power supply assembly 150, which will be described later.

Preferably, the base 112 is an aluminum alloy piece. Thus, the weight of the base 112 is small.

The base 112 is a flat plate structure. The base 112 is detachably connected to the inner side surface of the housing 111 by a fastener (e.g., a screw). Thus, the base 112 covers the opening 113 of the housing 111, thereby protecting the electrical components located in the housing 111.

The base 112 is used to connect to the bottom surfaces of the flutes of the corrugated sheet of the side walls and is located outside the bottom surfaces of the flutes.

In the case of the housing assembly 110 configured by connecting the housing 111 and the base 112 together, the dimension of the housing assembly 110 in the height direction D3 of the housing 111 is a height dimension. The height dimension of the housing assembly 110 is less than the depth of the flutes of the corrugated sheets of the container. Thus, the housing assembly 110 connected to the container does not protrude out of the grooves of the corrugated plate. The trusted security satellite terminal equipment is prevented from being collided and damaged in the process of transporting the container. In addition, the transportation of the container of the trusted security satellite terminal equipment is convenient to set.

Preferably, as shown in fig. 3, the inner side of the housing 111 is provided with a plurality of reinforcing ribs 114. The reinforcing ribs 114 extend in the height direction of the housing 111. The reinforcing bar 114 is provided with a mounting hole for connecting a fastener. This increases the strength of the case 111.

With continued reference to fig. 1-3, the trusted security satellite terminal device further includes an antenna arm assembly 120, an antenna circuit unit 130, a controller 140, and a power supply assembly 150.

The antenna arm assembly 120 is located within the housing 111. The length direction of the antenna arm assembly 120 is parallel to the length direction D1 of the housing 111. The antenna arm assembly 120 includes an antenna. The antenna is a transducer. An antenna converts a guided wave propagating through a transmission line (wire) into an electromagnetic wave (dielectric-free electromagnetic wave) propagating through an unbounded medium (usually free space), or vice versa.

The antenna arm assembly 120 is used to transmit and receive communication signals. The communication signals include low-orbit satellite signals to enable the controller 140 to communicate with low-orbit satellites.

As shown in fig. 1 to 3, the antenna circuit unit 130 is located in the housing 111. The antenna circuit unit 130 is electrically connected to the antenna arm assembly 120 for processing (e.g., de-noising, filtering) communication signals of the antenna arm assembly 120.

The controller 140 is located within the housing 111. The controller 140 is electrically connected to the antenna circuit unit 130 for communication with the antenna circuit unit 130, and thus with the low earth satellite through the antenna arm assembly 120.

The communication signal includes a transmission signal and a reception signal. The controller 140 can transmit a transmission signal in the form of a guided wave to the antenna circuit unit 130. The antenna circuit unit 130 processes the transmission signal in the form of a guided wave and transmits the processed transmission signal in the form of a guided wave to the antenna arm assembly 120. The antenna arm assembly 120 converts the transmission signal in the form of the guided wave into a transmission signal in the form of a dielectric-free electromagnetic wave, and transmits the transmission signal in the form of the dielectric-free electromagnetic wave to a predetermined network (a low orbit satellite network, a medium orbit satellite network, a cellular network, a GPS satellite network, and a beidou satellite network).

The antenna arm assembly 120 receives a reception signal in the form of a dielectric-free electromagnetic wave of a predetermined network, converts the reception signal in the form of the dielectric-free electromagnetic wave into a reception signal in the form of a guided wave, and transfers the reception signal in the form of the guided wave to the antenna circuit unit 130. The antenna circuit unit 130 processes the reception signal in the form of a guided wave and transmits the processed reception signal in the form of a guided wave to the controller 140.

Returning to fig. 1-3, the trusted secure satellite terminal device further includes a power supply component 150. The power supply assembly 150 is electrically connected to the controller 140 and the antenna circuit unit 130 through wires for supplying power to the controller 140 and the antenna circuit unit 130.

In this embodiment, the housing 111 is connected to the outer surface of the container through the base 112, the antenna arm assembly 120 is located in the housing 111, and the housing 111 is made of plastic. In this way, the antenna of the antenna arm assembly 120 can transmit or receive communication signals towards the direction of the housing 111 away from the base 112, and the housing 111 does not interfere with the antenna to transmit or receive communication signals outside the housing 111; in addition, under the condition that the trusted security satellite terminal equipment is connected to the container, the trusted security satellite terminal equipment does not protrude out of the grooves of the corrugated plates, and the trusted security satellite terminal equipment can be protected.

Preferably, as shown in fig. 1 to 3, a dimension of the case assembly 110 in the length direction D1 of the case 111 is a length dimension. The dimension of the housing assembly 110 in the width direction D2 of the housing 111 is a width dimension. The length dimension of the case assembly 110 is greater than the width dimension of the case assembly 110. Thus, the housing assembly 110 is a strip structure. Thus, the length direction D1 of the housing 111 may extend in the extending direction of the grooves of the corrugated plate (i.e., the height direction of the container). Whereby the housing assembly 110 can be conveniently arranged in the grooves of the corrugated plate.

Preferably, returning to fig. 1, the antenna arm assembly 120 includes a first antenna arm 121 and a second antenna arm 122. The length direction of the first antenna arm 121 and the length direction of the second antenna arm 122 both extend along the length direction D1 of the housing 111. An antenna interval exists between the first antenna arm 121 and the second antenna arm 122 along the length direction D1 of the housing 111. In this way, the first antenna arm 121 and the second antenna arm 122 are sequentially arranged along the length direction D1 of the housing 111, so that the first antenna arm 121 and the second antenna arm 122 are prevented from being overlapped together, and the height of the housing assembly 110 can be reduced as much as possible.

The controller 140 is located on the side of the antenna arm assembly 120 in the lengthwise direction D1 of the housing 111. Thereby, the height of the housing assembly 110 can be reduced as much as possible.

The power module 150 is located on the side of the controller 140 in the longitudinal direction D1 of the housing 111. Thereby, the height of the housing assembly 110 can be reduced as much as possible.

The antenna circuit unit 130 is located between the first antenna arm 121 and the second antenna arm 122 in the length direction D1 of the housing 111. Thereby, the height of the housing assembly 110 can be reduced as much as possible.

Further preferably, the first antenna arm 121, the antenna circuit unit 130, the second antenna arm 122, the controller 140, and the power supply assembly 150 are sequentially disposed along the length direction D1 of the housing 111.

Preferably, the antenna arm assembly 120, the antenna circuit unit 130, the controller 140, and the power supply assembly 150 are connected to the base 112. As such, the base 112 supports the antenna arm assembly 120, the antenna circuit unit 130, the controller 140, and the power supply assembly 150.

The housing 111 has a through hole (not shown). The trusted secure satellite terminal device further comprises a connector (not shown). The connector is electrically connected to the controller 140. The connector is arranged in the through hole in a penetrating mode.

Specifically, the through hole is located in the vertical wall of the housing 111. The standing wall extends in the height direction D3 of the housing 111. The vertical walls comprise end vertical walls and side vertical walls. The end walls are located at the ends of the housing 111 in the longitudinal direction D1 of the housing 111. The side standing walls are located at the ends of the case 111 in the width direction D2 of the case 111.

The through holes include a first through hole and a second through hole. The first through hole and the second through hole are spaced apart. The connector includes first connector and second connector. The first connector is electrically connected to the controller 140 through a wire. The first connector penetrates through the first through hole. Therefore, the external controller can be connected through the first through hole. The external controller may send a signal to the controller 140, and then send a signal to the antenna circuit unit 130 through the controller 140, so as to set the controller 140 and the antenna circuit unit 130. The specific setting mode can be set according to the requirement.

The second connector may be electrically connected to the controller 140 through a wire. The second connector can be used for an external power supply to provide electric energy for the trusted security satellite terminal equipment.

As shown in fig. 4, the trusted secure satellite terminal device further includes an acceleration sensor 160. The acceleration sensor 160 is located within the housing 111. The acceleration sensor 160 is electrically connected to the controller 140. The acceleration sensor 160 is used to sense an acceleration signal. The acceleration signal represents the current acceleration of the trusted secure satellite terminal device. The acceleration sensor sends an acceleration signal to the controller 140. The controller 140 receives the acceleration signal and determines whether the trusted secure satellite terminal device is in a stopped state based on the acceleration signal.

Specifically, when the acceleration signal indicates that the acceleration of the trusted secure satellite terminal device is 0 within a predetermined time period (for example, 10s), it indicates that the trusted secure satellite terminal device is in the stopped state.

If the trusted security satellite terminal device is in the inactive state, the controller 140 controls the antenna arm assembly 120 to transmit and receive communication signals less frequently. Therefore, the energy consumption of the trusted security satellite terminal equipment can be reduced, and the working time of the trusted security satellite terminal equipment can be prolonged.

Antenna arm assembly 120 is also used to send and receive positioning signals to enable controller 140 to be used to determine the current location of the trusted security satellite terminal device.

Specifically, the controller 140 is positioned by Beidou or GPS. Thereby, the current location of the trusted secure satellite terminal device can be determined.

The antenna arm assembly 120 is also used to send and receive cellular signals to enable the controller 140 to communicate with a cellular network.

The antenna arm assembly 120 is also used to transmit and receive mid-orbit satellite signals to enable the controller 140 to communicate with the mid-orbit satellite. At this time, the latter satellite communication module communicates with the medium orbit satellite.

Specifically, as shown in fig. 4, the controller 140 includes a central unit, a storage unit (not shown), a power management module, a cellular communication module, a satellite communication module, and a positioning module.

The Central Unit may be a CPU (Central Processing Unit). The power supply assembly 150 is electrically connected to the power management module. The solar cell panel is electrically connected with the power supply management module. The power management module is electrically connected with the CPU. Thus, the CPU controls the solar panel to supply power to the power supply assembly 150 through the power management module. The CPU also controls the power supply assembly 150 to discharge through the power management module.

The CPU is electrically connected with the storage unit to store the numerical value into the storage unit. The CPU is electrically connected to the acceleration sensor 160 to receive acceleration information of the acceleration sensor 160. The CPU is electrically connected to the cellular communication module to communicate with the cellular network through the cellular communication module. The CPU is electrically connected with the satellite communication module so as to be capable of communicating with the low-orbit satellite network through the satellite module. The CPU is electrically connected with the positioning module. The CPU communicates with the GPS satellite network through the positioning module to determine the current position of the trusted secure satellite terminal device. The CPU is communicated with the Beidou satellite network through the positioning module to determine the current position of the credible safety satellite terminal equipment.

Preferably, the controller 140 further includes a communication mode switching module. The signal mode switching module is used for switching a low-orbit communication mode of the CPU which communicates with a low-orbit satellite network through the satellite communication module and a cellular communication mode of communicating with a cellular network through the cellular communication module.

The controller 140 further includes an external interface, an interface unit, a sensing unit, and an execution unit. The external interface is used for connecting the interface unit, the sensing unit and the execution unit. The interface unit is used for electrically connecting to the connector so that the CPU is electrically connected with the connector. The sensing unit is used for electrically connecting various external sensors to acquire signals sensed by the external sensors. The external sensor may be a temperature sensor for sensing temperature or an ultrasonic sensor for sensing ultrasonic waves. The execution unit is used for being electrically connected with the execution mechanism so as to control the action of the execution mechanism. The actuator may be used to actuate the opening or closing of the doors of the container.

Preferably, the outer surface of the housing 111 is provided with identification information, such as a two-dimensional code. The identification information represents identity information of the trusted secure satellite terminal device. And a two-dimensional code is arranged on the shell 111 of each trusted security satellite terminal device. The identity information comprises the serial number, the production place, the production date and the like of the trusted secure satellite terminal equipment. Therefore, the identity information of the trusted security satellite terminal equipment can be obtained by scanning the two-dimensional code.

The controller 140 is provided with identification information therein. Thus, the identity information of the trusted security satellite terminal device can be obtained from the controller 140 via an external controller connected to the controller 140 via the first connector, and a predetermined network (e.g., a low-earth satellite network, a medium-earth satellite network, and a cellular network) in communication with the controller 140 via the antenna arm assembly 120.

Preferably, an identity security module is disposed within the controller 140. The identity security module contains identification information representing identity information of the trusted security satellite terminal device. The identification information set in the controller 140 is trusted authentication information of the physical fingerprint of the chip. The trusted authentication information of the chip physical fingerprint is generated based on a PUF (physical unclonable function). Therefore, the credible authentication information of the chip physical fingerprint generated based on the PUF is sensitive to physical detection and can resist invasive attacks. Therefore, the credible authentication information of the physical fingerprint of the chip is difficult to clone.

And identity credible security authentication is required to be carried out through the identity security module in each data exchange between the controller and the antenna circuit unit. This improves the security of data exchange between the controller and the antenna circuit unit.

The worker may select a mode of communication with the trusted secure satellite terminal device as desired. For example, if the worker is near the trusted security satellite terminal device, the worker may connect to the first connector through an external controller (e.g., a personal computer) to control the trusted security satellite terminal device. At this time, the staff can obtain the identity information of the current trusted security satellite terminal device and the configuration information stored in the storage unit by scanning the two-dimensional code of the trusted security satellite terminal device.

The staff may communicate with the trusted secure satellite terminal device via a low-orbit satellite network, a medium-orbit satellite network, or a cellular network. At this time, the worker can obtain the identity information of the current trusted secure satellite terminal device and the configuration information stored in the storage unit by reading the identification information in the controller 140.

The trusted secure satellite terminal device further comprises a solar panel (not shown). The solar cell panel is connected to a portion of the outer side of the case 111 away from the base 112. The solar panel is connected to the antenna circuit unit 130, the controller 140 and the power supply assembly 150, and is used for providing electric energy for the antenna circuit unit 130, the controller 140 and the power supply assembly 150.

In the case where the amount of power of the power supply assembly 150 is less than the predetermined amount of power, the controller 140 controls the power supply assembly 150 to stop discharging (stop supplying power to the controller 140 and the antenna circuit unit 130); the controller 140 controls the solar panel to supply power to the power supply assembly 150 to charge the power supply assembly 150; the controller 140 controls the solar cell panel to supply power to the controller 140 and the antenna circuit unit 130.

Preferably, a solar charging circuit is provided within the controller 140. As shown in fig. 5, the solar charging circuit includes an input end 210, an output end 220, a Metal Oxide Semiconductor (MOS) transistor 230, a photodiode, a resistor, a thermistor 260, a capacitor, a diode, an inductor 250, and a control chip 170.
