Embodiment 1

[0036] In this example, if figure 1 As shown, a kind of inspection gateway with gatekeeper function is provided, including an internal network processing unit 1 and an external network processing unit 2, and the inspection gateway also includes a data ferry unit, and the internal network processing unit 1 and the external network The processing unit 2 communicates via said data ferry unit.

[0037] The data ferry unit comprises: an arbitration circuit module 3, a bus selector 4 and a memory 5, and the memory 5 is a SPI (SDRAM) large-capacity memory; The network processing unit 2 is connected with the bus selector 4, and the bus selector 4 is also connected with the internal network processing unit 1, the external network processing unit 2 and the memory 5 respectively; The data command of the network processing unit 2 determines that the internal network processing unit 1 or the external network processing unit 2 has the right to use the bus of the inspection gateway, and the...

Embodiment 2

[0048] In this example, if image 3 As described above, a method for safely uploading intranet data to a cloud server is provided, which is applied to the inspection gateway provided in Embodiment 1, and the method includes the following steps:

[0049] Step S31, obtaining the inspection data and service data of the detected equipment through Ethernet;

[0050] Step S32, based on the arbitration circuit module and the bus selector, the right to use the inspection gateway bus is acquired by the internal network processing unit and the external network processing unit in turn;

[0051] Step S33, making the internal network processing unit write the inspection data and business data obtained in step S31 into a specific area of ​​the memory according to the corresponding configuration data of the internal network processing unit, and then release the right to use the inspection gateway bus;

[0052] Step S34, make the external network processing unit read the inspection data and ...

Embodiment 3

[0059] In one embodiment, such as Figure 4 As shown, a device for safely uploading intranet data to a cloud server is provided, including the following program modules:

[0060] The intranet data acquisition module 41 is used to acquire the inspection data and service data of the detected equipment through Ethernet;

[0061] The bus use right granting module 42 is used to obtain the use right of the inspection gateway bus by the internal network processing unit and the external network processing unit in turn based on the arbitration circuit module and the bus selector;

[0062] The data writing module 43 is used to make the internal network processing unit write the inspection data and business data obtained by the internal network data acquisition module 41 into a specific area of ​​the memory according to the corresponding configuration data of the internal network processing unit, and then release the inspection data of the internal network processing unit. Check the rig...

Abstract

The invention discloses an inspection gateway with a gatekeeper function and a data uploading and issuing method. The inspection gateway comprises an intranet processing unit and an extranet processing unit, and further comprises a data ferry unit, and the data ferrying unit comprises an arbitration circuit module, a bus selector and a memory. According to the routing inspection gateway provided by the invention, only one processing unit can perform read-write operation on the memory at the same time through the bus selector, so that the routing inspection gateway provided by the invention cannot realize connection with another network no matter whether the intranet processing unit or the extranet processing unit is invaded by malicious applications or single-party configuration is changed, and the routing inspection efficiency is improved. The attack cannot be implemented, so that the network security is ensured; therefore, the routing inspection gateway can prevent threats caused by illegal access to the intranet, solves the problem of communication security between the intranet and the extranet, and has high reliability; and as an expensive gatekeeper or a network firewall is omitted, the investment cost and the installation space of a customer are saved, and the system has the advantages of low cost and energy conservation.

Description

technical field [0001] The present application relates to the technical field of network security equipment, in particular to an inspection gateway and a method for uploading and sending data. Background technique [0002] The purpose of equipment inspection is to grasp the operation status of the equipment and the changes in the surrounding environment, find out the defects of the facilities and hidden dangers to safety, and take effective measures in time to ensure the safety of the equipment and the stability of the system. Therefore, the inspection of the equipment is very important. work. Although there are devices on the market that can realize automatic inspection (network on-off, delay, crash, etc.), these current automatic inspection devices have relatively single functions and cannot well guarantee data communication security. Contents of the invention [0003] Based on this, in view of the above technical problems, the embodiment of the present invention provid...
