specific Embodiment approach 1

[0017] Specific implementation mode one: the following combination figure 1 Describe this embodiment, the wood drying remote monitoring system based on DSP described in this embodiment includes a remote server, a monitoring host and a field controller, and the field controller includes a microprocessor 1, a temperature and humidity sensor 2, a balance moisture content Sensor 3, detection module 5, early warning module 6, control module 7, multi-way switch 9, drive module 8, and n wood moisture content sensors 4, n is a natural number,

[0018] The temperature and humidity sensor 2 collects the temperature and humidity signal of the drying kiln, and the temperature and humidity signal output end of the temperature and humidity sensor 2 is connected with the temperature and humidity signal input end of the detection module 5;

[0019] The balanced moisture content sensor 3 collects the balanced moisture content signal of the drying kiln, and the balanced moisture content signal ...

specific Embodiment approach 2

[0024] Specific embodiment two: the difference between this specific embodiment and the wood drying remote monitoring system based on DSP described in specific embodiment one is that the field controller can further include a liquid crystal touch screen 10, which can communicate with the microprocessor 1 through the liquid crystal touch screen 10 For data interaction.

[0025] In this embodiment: the current state of the drying kiln can be displayed through the liquid crystal touch screen 10, and some drying parameters can also be set.

[0026] In terms of hardware design: the field controller adopts DSP2812 core board LT8504 embedded development board for development and design, mainly completes the design of external storage circuit, touch screen interface circuit, signal input and output drive circuits, and connects with the serial port of the monitoring host to achieve reliable communication .

[0027] In terms of software design: the monitoring host uses the object-orien...

Abstract

The invention discloses a wood drying remote monitoring system based on a DSP (digital signal processor), which relates to a wood drying remote monitoring system and solves problems of low drying efficiency and complication in operation of an existing wood drying remote monitoring system. The wood drying remote monitoring system comprises a remote server, a monitoring host and a field controller. The monitoring host and the field controller are in data transmission by a serial bus, the monitoring host and the remote server are in data transmission via an Internet according to the TCP (transmission control protocol), and the field controller can run independently, can also receive various commands from the remote server and the monitoring host via a network bus and the serial bus and feeds data back to the monitoring host after the commands are executed. The wood drying remote monitoring system is applicable to automatic wood drying places with middle and large-size drying kilns.

Description

technical field [0001] The invention relates to a remote monitoring system for wood drying based on DSP, which belongs to the field of monitoring. Background technique [0002] At present, the wood drying process has gradually developed and matured. Computers have been widely used in my country's wood drying industry. Wood drying has been developed from manual control by operators to computer-based automatic control. However, there is still a certain gap between the automation degree of domestic wood drying equipment and foreign countries. It is mainly manifested in: [0003] 1. Relying heavily on the experience and professional knowledge of operators: although some wood drying enterprises have realized semi-automatic and fully automatic control, however, operators, especially technicians, are required to have certain basic knowledge of wood drying and instrument maintenance ; Otherwise, if the abnormal phenomenon in the drying process cannot be dealt with in time, the ins...
