Problems solved by technology

The traditional monitoring system can only display simple monitoring data to the monitor, and the monitoring between devices is isolated, which makes it impossible for users or producers to understand and monitor the status, usage and distribution of working devices as a whole. Analysis, this will inevitably cause a waste of natural resources and human resources, and cannot give full play to the role of equipment

Embodiment 1

[0027] like figure 1 As shown, the intelligent touch screen display control system based on CAN bus described in this embodiment includes a central signal processing control core board module (101), which is characterized in that: the central signal processing control core board module (101) is composed of Composed of central processing chip, FLASH circuit, clock circuit and interface circuit; central signal processing control core board module (101) connected with USB interface module (103), SD card storage module (104), system startup selection module (105), camera module (106), real-time clock module (107), power management and reset module (111) and RS232 serial port communication interface module (112); central signal processing control core board module (101) communicates with GPS satellite positioning module (110) The antenna (113) is connected, and the GPS antenna (113) is placed on the top of the cotton picker cab for receiving satellite signals; the central signal pr...

Embodiment 2

[0029] This embodiment is basically the same as Embodiment 1, and the special features are as follows:

[0030]The USB interface module (103) is used to debug the system program and synchronize with the computer; the system startup selection module (105) is composed of a dial switch circuit, which is used to select the startup mode of the intelligent touch screen display control system based on the CAN bus, and determines Whether the system starts from the SD card or starts from the FLASH, the operating system and the monitoring software have been programmed and compiled in this embodiment, and this module can be directly loaded into the FLASH to start; the camera module (106) is composed of the ov9650 module and the camera interface circuit, it passes through the I 2 The C bus is connected with the central signal processing control core board module (101), which is placed at the tail of the cotton picker for monitoring the external environment; the real-time clock module (107...

Embodiment 3

[0035] Present embodiment is identical with embodiment two, is example with cotton picker, specifically as follows:

[0036] The intelligent touch screen display control system based on the CAN bus uses the USB interface module (103), the SD card storage module (104), the system startup selection module (105) and the RS232 serial communication interface module (112) to adapt the tailored The WINCE operating system of the cotton picker is programmed into the control system, and it can run normally.

[0037] The intelligent touch screen display system based on the CAN bus of the above cotton picker is installed in the cab of the cotton picker; the CAN node of the lower computer is connected to the bus through the CAN high interface (301) and the CAN low interface (302) of the CAN communication module (108) Above; the GPS antenna (113) is fixed on the top of the cab and placed facing the sky; the GPRS telecommunication antenna (114) is fixed on the inner wall of the cab; the SD c...

Abstract

The invention discloses an intelligent touch screen display control system and method based on a CAN bus. The device comprises a central signal processing control core board module, a liquid crystal display and touch screen interface module, a USB interface module, an SD card storage module, a system start selection module, a camera module, a real-time clock module, a CAN communication module, a GPRS remote communication module, a GPS module, a power management and reset module, an RS232 serial port communication interface module and the like. The display control system has multiple configurable CAN communication Baud rates, is provided with a touch display screen and has an acquisition cycle capable of being set. The system has high intelligence, universality, compatibility and expansibility when a Windows CE operation system runs. The system is provided with the camera module so as to monitor real-time environment conveniently, is provided with the GPS module and the GPRS module so as to facilitate system positioning and remote data analysis and sharing, and can meet the requirement of data acquisition in various states of the CAN bus.

Description

technical field [0001] The invention relates to a data collection and display control device and method in the technical field of engineering monitoring and communication, and belongs to the technical field of electronic monitoring of electromechanical equipment, in particular to an intelligent touch screen display control system and method based on CAN bus. Background technique [0002] During the operation of the engineering system, it is often necessary to monitor the status of the equipment at work and the working environment. The traditional monitoring system can only display simple monitoring data to the monitor, and the monitoring between devices is isolated, which makes it impossible for users or producers to understand and monitor the status, usage and distribution of working devices as a whole. Analysis, this will inevitably cause a waste of natural resources and human resources, and cannot give full play to the role of equipment. An effective way is to upload...
