Communication and display system of agricultural machinery small intelligent terminal based on Internet of things

Abstract

The invention relates to a communication and display system of an agricultural machinery small intelligent terminal based on Internet of things. The system comprises a master chip, a can bus master transceiver chip, a USB transceiver chip and a USB interface on a printed circuit board. The USB transceiver chip is connected to the USB interface, and the USB interface is used for connecting a mobile terminal such that the mobile terminal receives various parameters of an agricultural machinery and each parameter of the agricultural machinery is displayed through the agricultural machinery application of a mobile terminal, and the functions of alarm, navigation, data upload and update program download of the agricultural machinery are realized. According to the system, a GPS module and a GPRS module are not installed, through the mobile terminal such as a mobile phone and an IPAD and through a serial port and a data line, the system is connected to the agricultural machinery small intelligent terminal, the functions of virtual instrument panel display, communication with an upper computer, data packet sending, update package download and the like are realized, and various functions of an intelligent agricultural machinery still can be realized on the basis of greatly reducing the production cost of an agricultural machinery intelligent terminal.

Problems solved by technology

[0002] my country is a large agricultural country, but most of the agricultural production is basically completed by human labor. For example, in most rural areas, operations such as sowing, fertilization, irrigation and harvesting mainly rely on pure human labor, which is not only inefficient, but also affects the growth and harvest of crops.

Even if mechanized sowing and harvesting are realized in some places, human cooperation is usually required, and mechanized operations such as sowing and harvesting are independent of each other and are not reasonably connected, which also affects the efficiency and production cycle of agricultural machinery operations.

[0003] First, the existing intelligent terminals for agricultural machinery are bulky and cumbersome, and are not suitable for small agricultural machinery for special operations

In addition, the dashboards of agricultural machinery intelligent terminals need to be equipped with GPS modules, GPRS modules, antennas and other hardware. The cost is high, and it is not easy to promote and popularize agricultural machinery intelligent terminals.

[0004] Second, in addition, although in the prior art, the data collected by the intelligent terminal of agricultural machinery is displayed through the APP in mobile terminals such as mobile phones or IPADs, but if it is displayed through the APP, the intelligent terminal of agricultural machinery must first upload the data packet to the host computer. Then download the data of the agricultural machinery to the APP. During the upload and download, data transmission is required, and the communication fee is extremely high.

[0005] Third, traditional agricultural machinery intelligent terminals require multiple functions such as intelligent display, wireless communication, positioning, download and update instructions, etc., so the main chip used is mostly a high-performance main chip, and the manufacturing cost is relatively high, and there is no independent storage area. Low, due to the additional configuration of memory will increase the cost

Fourth, no lithium battery and power supply circuit are installed, and only the battery in the mobile terminal such as mobile phone or IPAD or the storage battery in the agricultural machinery supplies power to the small intelligent terminal of the agricultural machinery.
