[0033] Embodiment one

[0034] Figure 1 A system architecture diagram of a container monitoring system is provided for the first embodiment of the present application. As shown in the figure, the system comprises: Figure 1

[0035] The main monitoring module 1 and a plurality of first monitoring modules 2 constitute a series loop; when there is a failure of the first monitoring module 2, the first address data is sent to the main monitoring module 1 along the line without failure by the first monitoring module 2 without failure.

[0036] The first address data includes the address of the first monitoring module 2.

[0037] ​The first address data uploaded by each first monitoring module 2 is monitored by the main monitoring module 1, and the first address data includes address information of the first monitoring module 2, and can also include other data detected by the first monitoring module 2, such as state data in the container power distribution box. Specifically, the main monitoring module 1 and the plurality of first monitoring modules 2 are connected in series, and form a series loop, and each two first monitoring modules 2 can communicate with each other, and each first monitoring module 2 can also communicate with the main monitoring module 1.

[0038] When the first monitoring module 2 fails, the failure of the first monitoring module 2 causes the loop to be disconnected at the first monitoring module 2, and the two adjacent first monitoring modules 2 that do not fail can upload the first address data along the first monitoring modules 2 that do not fail, and the main monitoring module 1 can also supply power to the first monitoring modules 2 that do not fail along the first monitoring modules 2 that do not fail. In addition, the main monitoring module 1 can determine that the first monitoring module 2 that does not upload the first address data is the first monitoring module 2 that fails according to the received first address data.

[0039] In addition, when a line in the loop is disconnected, the first monitoring modules 2 connected at both ends of the line can upload the first address data along the line that does not fail, and the main monitoring module 1 can also supply power to the first monitoring modules 2 that do not fail along the line that does not fail. In addition, the main monitoring module 1 can determine the location of the failed line according to the time difference between the current received first address data and the last received first address data sent by the corresponding first monitoring module 2, and the historical time difference of the received first address data. That is, once a line fails, one of the first monitoring modules 2 at both ends of the failed line needs to change the data transmission path, and the transmission path will be longer, so the failed line can be determined.

[0040] The technical scheme of the embodiment of the application forms a series loop by connecting the main monitoring module and the plurality of first monitoring modules, so that when any first monitoring module in the loop fails, the other first monitoring modules can obtain power along the line that does not fail and work normally, and can continue to send the first address data to the main monitoring module along the line that does not fail, thereby ensuring the normal operation of the container monitoring system. In addition, the main monitoring module can determine the address of the first monitoring module that does not upload the first address data according to the received first address data, and locate the first monitoring module, so as to repair the failure of the first monitoring module as soon as possible, thereby reducing the difficulty of manual screening.

[0041] Embodiment two

[0042] Figure 2This is a system architecture diagram of the container monitoring system provided in Embodiment 2 of the present invention. Figure 2 As shown, in this system, the port side of the ship includes a first line 7 consisting of multiple first monitoring modules 2 connected in series; the starboard side of the ship includes a second line 8 consisting of multiple first monitoring modules 2 connected in series, and the first monitoring modules 2 are installed in the distribution box 4.

[0044] The first monitoring module 2 is located inside the distribution box 4 and can be used to detect the status data inside the distribution box 4 and upload the detected data to the main monitoring module 1. The actual distribution box 4 is generally located on the port and starboard sides of the ship. When the first monitoring module 2 on the port side, the first monitoring module 2 on the starboard side, and the main monitoring module 1 form a series circuit, the first monitoring modules 2 in the distribution boxes 4 on the port and starboard sides can communicate with each other, and the first monitoring modules 2 in the distribution boxes on the port and starboard sides can also communicate with the main monitoring module 1.

[0045] Specifically, such as Figure 2 As shown, the first line 7 includes multiple first monitoring modules 2 connected in series, and the first monitoring modules 2 are housed in the distribution box 4; similarly, the second line 8 includes multiple first monitoring modules 2 connected in series, and the first monitoring modules 2 are housed in the distribution box 4; the first monitoring module 2 at the first end of the first line 7 is connected to the main monitoring module 1 via a cable, i.e. Figure 2 In the first monitoring module 2 on the port side of the ship, the leftmost one of the first lines 7 is connected to the main monitoring module 1; similarly, the first monitoring module 2 at the first end of the second line 8 is connected to the main monitoring module 1 via a cable. Figure 2 The leftmost first monitoring module 2 of the second line 8 on the starboard side of the ship is connected to the main monitoring module 1; in addition, the rightmost first monitoring module 2 of the first line 7 on the port side of the ship is cable connected to the rightmost first monitoring module 2 of the second line 8 on the starboard side of the ship.

[0046] In one specific implementation, the first monitoring module 2 is connected to multiple second monitoring modules 5 respectively, and is used to receive the second address data corresponding to the second monitoring module 5, wherein the first address data includes the second address data.

[0047] The second monitoring module 5 can be connected with the first monitoring module 2 in the power distribution box 4 through a cable, and the second monitoring module 5 can send the second address data collected by the second monitoring module 5 to the first monitoring module 2; the second monitoring module 5 can be arranged in the container 6, and the second address data uploaded by the second monitoring module 5 includes the address data of the second monitoring module 5, and can also include the environmental data such as temperature, wind speed and humidity in the container. In addition, the second address data is included in the first address data, so that when the first monitoring module 2 sends the first address data to the main monitoring module 1, the main monitoring module 1 can also receive the second address data of all second monitoring modules 5 in the container monitoring system, so as to monitor the state of all containers in the system in real time. When a container fails, the main monitoring module 1 can also quickly respond, identify the address of the failure, and respond in time.

[0049] In practice, the first monitoring module 2 can be electrically connected with a plurality of sockets 3, and each socket 3 can be electrically connected with a plurality of second monitoring modules 5 through a cable. For example, the power distribution box 4 can be connected with 6 container socket boxes; each container socket box can be connected with 10 containers; one first monitoring module 2 can be installed in each power distribution box 4, and one second monitoring module 5 can be installed in each container 6. The second monitoring module 5 and the socket 3, the socket 3 and the first monitoring module 2, and the first monitoring module 2 and the main monitoring module 1 can be connected through a cable.

[0050] Specifically, the main monitoring module 1 and the plurality of first monitoring modules 2 communicate through power line carrier; the first monitoring module 2 and the second monitoring module 5 communicate through power line carrier. In addition, the main monitoring module 1 and the plurality of first monitoring modules 2 communicate through DANBus communication protocol; the first monitoring module 2 and the second monitoring module 5 communicate through DANBus communication protocol, so that the address of each second monitoring module 5 in the container can be addressed.

[0051] In a specific embodiment, the main monitoring module 1 includes a wiring module 11, a monitoring terminal 12 electrically connected with the wiring module 11, and a monitoring alarm module 13;

[0052] The wiring module 11 is used for receiving the first address data corresponding to the first monitoring module 2, and uploading the first address data to the monitoring terminal 12;

[0053] The monitoring terminal 12 analyzes the first address data, and sends an alarm instruction to the monitoring alarm module 13 when a failure occurs.

[0054] The monitoring alarm module 13 is used to send an alarm signal according to the received alarm instruction.

[0055] The wiring module 11 can obtain the container state data uploaded by the second monitoring module 5 in all containers in the system through the power line carrier communication mode, of course, the address of the second monitoring module 5 is also included, and the address data of all first monitoring modules 2 and the monitored state data of the distribution box can also be obtained. After the wiring module 11 receives the first address data, the data can be uploaded to the monitoring terminal 12, and the monitoring terminal 12 completes the analysis and processing of the data. When a fault occurs, an alarm instruction can be sent to the monitoring alarm module 13, and the monitoring alarm module 13 sends an alarm signal according to the received alarm instruction

[0056] Specifically, the wiring module 11 is electrically connected with the first monitoring module 2 at the first end of the first line 7 and the first monitoring module 2 at the first end of the second line 8, respectively, so that the first monitoring data uploaded by each first monitoring module 2 can be obtained through the power carrier communication mode.

[0057] In a specific embodiment, the monitoring terminal 12 includes a container detection system host 121, a display 122 connected with the container detection system host, a keyboard 123, a printer 124 and an uninterruptible power supply 125; the display 122 is connected with the printer 124 and the uninterruptible power supply 125, respectively.

[0058] The container detection system host 121 is used to analyze and process the received first monitoring data, and the staff can check the state data of the container through the display 122, or check the corresponding fault information on the display 122 when a fault occurs; and the staff can also input control instructions on the container detection system host 121 through the auxiliary equipment of the mouse and keyboard according to the data displayed on the display 122, to realize fault processing and other operations. The uninterruptible power supply 125 can supply power to the container detection system host 121, the display 122 and the printer 124 at the same time.

[0059] The technical scheme of the embodiment of the present application comprises a series loop formed by the main detection module and the plurality of first monitoring modules, so that when any first monitoring module in the loop fails, the other first monitoring modules can obtain power along the line not failing and work normally, and can continue to send the first address data to the main monitoring module along the line not failing, thereby ensuring the normal operation of the container monitoring system. The first monitoring modules are connected to the plurality of second monitoring modules in the containers, and the second address data output by the second monitoring modules is packaged and sent to the main detection module, so that the main detection module can monitor all the containers in the system. When a container fails, the main monitoring module 1 can quickly locate the container, identify the address of the failure, and make a timely response.

The main monitoring module 1 can analyze the first address data to determine whether the first monitoring module has failed; when the first monitoring module 2 fails, the failure of the first monitoring module 2 causes the loop to be disconnected at the first monitoring module 2, and the two adjacent first monitoring modules 2 of the first monitoring module 2 can upload the first address data along the first monitoring module 2 without failure, and the main monitoring module 1 can also power the first monitoring module 2 without failure along the first monitoring module 2 without failure. In addition, the main monitoring module 1 can determine that the first monitoring module 2 without uploading the first address data is the first monitoring module 2 with failure according to the received first address data. And when any first monitoring module fails, other first monitoring modules without failure can obtain power along the line without failure and work normally, and can send the first address data to the main monitoring module 1.

[0067] In addition, when a loop in the loop is disconnected, the first monitoring module 2 connected to the line can upload the first address data along the line without failure, and the main monitoring module 1 can also power the first monitoring module 2 without failure along the line without failure. In addition, the main monitoring module 1 can determine the location of the fault line according to the time difference between the current received first address data and the last received first address data sent by the corresponding first monitoring module 2, and the historical time difference of the received first address data, that is, once a line fails, one of the first monitoring modules 2 at both ends of the fault line needs to change the data transmission path, and the transmission path will be longer, so that the fault line can be determined.
