Abstract
The invention relates to a distributed vegetable planting greenhouse monitoring system based on a CAN (Controller Area Network) bus. The distributed vegetable planting greenhouse monitoring system comprises an upper monitoring machine, a CAN host node, CAN slave codes, wherein the upper monitoring machine is responsible for receiving and managing monitoring data of each node of the system, sending a control command and displaying the dynamic parameter of each control unit and the equipment status in real time; the CAN host node is connected with the upper monitoring machine and the CAN bus, harmonizes the communication of the upper monitoring machine and each CAN node, meanwhile completes conversion of the data of the CAN bus and the data of a serial communication mode of the upper monitoring machine, and caches the data information of each CAN slave node; the CAN slave codes are intelligent monitoring modules, and each intelligent monitoring module comprises a single chip microcomputer and a CAN communication controller SJA1000 connected with the single chip microcomputer; the temperature, the humidity and the oxygen content in a system tunnel are measured and sent to the CAN bus through the CAN communication controller SJA1000; and the monitoring data is stored, is regularly uploaded to an upper computer and is polled through the upper computer.
Description
Technical field
The present invention relates to a kind of growing vegetables booth system, relate in particular to distributed growing vegetables booth supervisory system based on the CAN bus.
Background technology
At present, China's " vegetable basket project " develops, and the fruits and vegetables base more than the scale is just in cumulative year after year; But,, often still adopt labor-intensive mode that green house of vegetables is carried out daily management because input is bigger in current vast rural area; So management is stronger to people's dependence, and management good and badly often depend on the judgement of personnel's experience to thing is so sometimes because careless and inadvertent; Cause canopy temperature, the erroneous judgement of humidity etc. is disconnected, influences output.Also there is the single-skin drum of employing machine the physical quantitys such as humiture in the booth to be detected in the traditional mode as controller; But the scale function is little; Set up the infrastructure duplicate construction; Only be that a booth or several booth partial data parameters are on every side carried out limited detection, function singleness more can't realize remote monitoring etc.
Summary of the invention
The object of the invention is exactly for the problems referred to above, and a kind of distributed growing vegetables booth supervisory system based on the CAN bus is provided, and it has, and cost is low, the good advantage of implementation.
To achieve these goals, the present invention adopts following technical scheme:
Based on the distributed growing vegetables booth supervisory system of CAN bus, it comprises
The upper monitoring machine is responsible for reception and management, the transmission of control command and the real-time demonstration of each control module dynamic parameter and equipment state to each monitoring nodes data of system;
CAN host node: connect upper monitoring machine and CAN bus; Coordinate upper monitoring machine and each CAN communicating by letter from node; Accomplish the conversion of the data of CAN bus data and upper monitoring machine serial communication pattern simultaneously; Each data message from node of buffer memory is alarmed to notify the maintainer to handle alarm signal;
CAN is intelligent monitoring module from node, comprising single-chip microcomputer and the CAN communication controler SJA1000 that is connected, temperature, humidity, oxygen level in the system tunnel is measured and is sent into the CAN bus through CAN communication controler SJA1000; The CAN host node is stored monitor data, regularly is uploaded to host computer, and accepts the poll of host computer; If exceed normal range of operation, then alarm is reported situation simultaneously in real time to host computer.
Said serial communication pattern adopts the RS-232 communication modes.
Said CAN adopts the DS1822 digital thermometer chip from node.
Said CAN bus respectively is provided with the resistance of a 124W respectively at the two ends of bus.
Principle of work of the present invention
In practice, make full use of the CAN bus, not only less investment on hardware circuit; But also the advantage of utilization CAN; Sampling upper monitoring machine, CAN host node, CAN utilize the sensor circuit that is provided with from the node periphery from joint system, realize the temperature in the green house of vegetables, humidity, oxygen level etc. are effectively detected; If difference is arranged, can alarm through network.
Beneficial effect of the present invention:
The mode of sampling CAN bus has been integrated the peripheral detection limit sensing facilities that must have, and makes full use of the hardware less investment of CAN, and the characteristics of reliable operation are set up upper monitoring machine, CAN host node, CAN from joint system, satisfy the needs of growing vegetables booth.
