Problems solved by technology

[0003] At present, in the embedded control system, the controller will try to integrate the acquisition circuit of the sensor and the driving circuit of the actuator, so that the controllers of the embedded control system of different applications are very different and cannot be standardized
In addition, the current controller in the embedded control system is composed of discrete chips such as processor chips, power chips, crystal oscillator chips, and interface chips interconnected through PCBs. In this case, chip-based controllers are impossible.
Moreover, this kind of controller has disadvantages such as heavy PCB board-level development workload, more wiring harnesses, more pins, and poor reliability.

Embodiment 1

[0034] figure 1 It is a structural schematic diagram of a traditional controller used in an embedded control system in the prior art. figure 2 It is a structural schematic diagram of the controller used in the embedded control system provided by the embodiment of the present invention.

[0035] Such as Figure 1-2 As shown, compared with the traditional controller, the controller for the embedded control system provided by the embodiment of the present invention only retains the circuit for implementing logic or mathematical calculation and communication functions, eliminates the IO processing circuit, and uses CAN and / or Or the CAN FD communication mode is connected with the intelligent sensor and the intelligent actuator, and the intelligent sensor and / or the intelligent actuator are used to realize the function of the IO processing circuit of the rejection. Since only the computing and communication functions are reserved, the sensing data can be transmitted between the ...

Embodiment 2

[0045] Figure 6 It is a schematic flowchart of a control method for a controller of an embedded control system provided by an embodiment of the present invention. Such as Figure 6 As shown, the control method for the controller of the embedded control system provided by the embodiment of the present invention includes the following steps:

[0046] 11. The controller obtains the value of the required physical quantity from the smart sensor through CAN and / or CAN FD communication;

[0047] 12. The corresponding control value is calculated by the preset program of the controller with the value as input, and the control value is sent to the intelligent actuator by means of CAN and / or CAN FD communication;

[0048] 13. After the intelligent actuator receives the control signal, it executes the corresponding operation of the control command corresponding to the control value.

[0049] For example, the application process of the control method for the controller of the embedded ...

Abstract

The invention discloses a controller for an embedded control system and a control method of the controller, and belongs to the field of industrial control. The controller provided by the invention keeps a circuit which achieves the functions of logic or mathematical calculation and communication, and eliminates an IO processing circuit. The controller is connected with an intelligent sensor and / orintelligent executor in CAN and / or CAN FD communication modes. The intelligent sensor and / or intelligent executor are / is used for achieving the function of the deleted IO processing circuit. According to the invention, the controller and control method can enable the size of the controller to be reduced, the weight to be reduced, the cost to be reduced and the reliability to be improved. Moreover, the number of pins of a controller interface is reduced, and the number of wire harnesses of the embedded control system is reduced. The development work of the embedded control system is reduced, and the flexibility is improved. The controller is good in application prospect in the related fields of industrial control, automobile and military industry.

Description

technical field [0001] The invention relates to the fields of industrial control, automobile and military industry, and in particular to a controller used in an embedded control system and a control method thereof. Background technique [0002] The so-called embedded application technology refers to a small or microcomputer device with complete functions as a component or subsystem, and organically constitutes a more reliable and technically stable system with a more powerful and complete system with a carrier. The main index requirements of the system: real-time, high efficiency, safety, stability and reliability, compact structure, easy tailoring, and good openness. Real-time is event-driven and time-driven capabilities, based on the kernel's structural model and process management mechanism; high efficiency includes system startup speed, running speed, and message delivery efficiency; stability and reliability include stability, security Performance indicators related to...
