Embodiment Construction

[0022] Below in conjunction with accompanying drawing, structure principle and working principle of the present invention are described in detail:

[0023] Please refer to figure 1 , figure 1 It is a functional block diagram of a control system according to an embodiment of the present invention. like figure 1 As shown, the control system 10 has a server 120 and a gateway 140 . The server 120 communicates with the gateway 140 in a wired or wireless manner. The gateway 140 is electrically connected to the local controller 30 . In one embodiment, the gateway 140 communicates with the local controller 30 via a Controller Area Network (CAN).

[0024] The server 120 is used for encrypting the control signal according to the first public key to generate the first encrypted signal. The control signal is, for example, from the control terminal 20 . The control terminal 20 is, for example, the user's mobile phone, tablet, notebook computer or other electronic device with computi...

Abstract

A control system and a control method, the control system has a server and a gateway. The server is used for encrypting the control signal according to the first public key to generate the first encrypted signal. The gateway is electrically connected to the local controller. The local controller controls the electronic device according to at least one parameter. The gateway is used to communicate with the local controller via the controller area network. The gateway is used for decrypting the first encrypted signal according to the first private key to obtain the control signal. The gateway is used for obtaining at least one parameter of the local controller according to the control signal to generate a monitoring signal, or the gateway is used for instructing the local controller to adjust at least one parameter according to the control signal. The first private key and the first public key belong to the same pair of keys. The invention also discloses a control method of the control system.

Description

technical field [0001] The invention relates to a control system and a control method, in particular to a control system and a control method for encrypted communication. Background technique [0002] At present, some of the tool devices close part of the system so that ordinary users cannot directly access them, so as to prevent unprofessional users from setting unreasonable parameter values, which may damage the tool device and even cause danger. For such a tool device, it is usually necessary to adjust it by means of a special adjustment tool. [0003] Taking car tuning tools as an example, the standard tuning tools currently available in the market are all developed on a PC-base basis in order to achieve a high level of real-time tuning. However, in the case of using the computer-based method, the user needs to use a physical circuit for the computer besides many steps such as installing the program and setting the program environment. [0004] At present, there are ma...
