Problems solved by technology

[0005] However, due to the various types of curing rooms and their continuous development, a unified communication standard for tobacco leaf curing controllers has not been formulated for a long time
On the other hand, even if a communication standard is formulated, a large number of existing controllers are difficult to adapt to the new standard through upgrading, and if all of them are replaced, it will cause a lot of waste

Embodiment

[0057] Embodiment: The present invention describes a wireless data collection device, collection method, self-adaptation method and use method for a tobacco leaf curing controller.

[0058] 1. The installation position and function of the wireless data acquisition device

[0059] as attached figure 1 As shown, the wireless data acquisition device of the present invention is connected in series between the dense barn controller and the dry-wet bulb temperature sensor, without the need to modify the existing controller and dry-wet bulb temperature sensor, it can be plug-and-play, and the wireless data acquisition device Read the data of the wet and dry bulb temperature sensor and send it to the server through the mobile network.

[0060] According to the technical specifications for dense curing barns in the document No. 418 [2009] of the National Tobacco Office, both dry bulb and wet bulb temperature sensors use DS18B20 digital sensors, and each barn uses 4 sensors, which are: u...

Abstract

The invention discloses a wireless data acquisition device, an acquisition method, a self-adaptive method and a use method for a tobacco leaf curing controller, and mainly relates to the technical field of tobacco leaf curing. The system is characterized in that a wireless data acquisition device is provided with two double-row bent seats, one double-row bent seat is connected with a controller in a curing barn, and the other double-row bent seat is connected with a sensor in the curing barn; a single chip microcomputer, a wireless communication module and a power supply circuit are arranged in the wireless data acquisition device; the power supply circuit comprises a boosted circuit and a charging circuit, one end of the boosted circuit is connected with a power line of a sensor in the curing barn, the other end of the boosted circuit is connected with the charging circuit, the charging circuit is connected with the wireless communication module, and the charging circuit comprises an energy storage element. A controller communication protocol is not involved, the data of the curing barn dry-wet bulb temperature sensor are directly collected and sent to the server, the system can be compatible with most controllers at present, and the system has universality and is convenient to install and use.

Description

technical field [0001] The invention relates to the technical field of tobacco leaf curing, in particular to a wireless data collection device, collection method, self-adaptive method and use method for a tobacco leaf curing controller. Background technique [0002] In "Technical Specifications for Intensive Baking Barns (Trial Implementation) Revised Edition" (National Tobacco Ban Zong [2009] No. 418), the RS485 interface reserved for external control is specified for the barn controller, and the MODBUS communication protocol is adopted, which can be used to connect to the Internet of Things module for remote monitoring. However, this technical specification does not stipulate a unified MODBUS communication protocol and remote monitoring platform. Therefore, the RS485 interface communication protocols of the controllers of various manufacturers are different, and the remote monitoring platforms established by each are independent of each other, and the operation interface i...
