Abstract

The invention discloses a control device of a variable-frequency air compressor. The control device comprises an upper computer and a lower computer; the upper computer is used for installing download software written by a VB (visual basic) program and is provided with a serial port which transmits data by the aid of a MODBUSRTU protocol; the lower computer is provided with a 485 interface and is in communication connection with the serial port of the upper computer via the 485 interface, and a BOOT application program used for initializing a peripheral is embedded in the lower computer. The control device has the advantages that the lower computer can automatically response to operation of the upper computer without being operated by operators, and a current state can be displayed on a display interface of the lower computer; the control device is a non-universal controller and accordingly is low in cost.

Description

一种变频空气压缩机的控制装置 Air compressor frequency variable control means

技术领域 FIELD

[0001] 本发明涉及一种变频空气压缩机的控制装置。 [0001] The present invention relates to a control device for an air compressor of the inverter.

背景技术 Background technique

[0002] 随着工控行业的快速发展,空压机成为各行各业必不可少的专业设备之一。 [0002] With the rapid development of the industrial sector, air compressor all walks of life to become one of the essential professional equipment. 而变频空压机又因其在节能减排上的效果现已经慢慢被众多使用厂家所接受。 The inverter compressor but also because the effect on energy saving slowly now has been accepted by many manufacturers use. 现变频空压机控制部分基本区分为两大类:一类为使用通用型控制器(如PLC加显示文本)作为变频空压机的控制核心,还有一类是使用专用控制器(如单片机系统)作为变频空压机的控制核心。 Inverter compressor control section is now substantially be divided into two categories: one using a general-purpose controller (such as PLC and text) as the control center of the inverter compressor, there is a class is a dedicated controller (e.g., microcontroller system ) as the control variable frequency air compressor.

[0003] 两大类的应用各有优缺点,通用型控制器优点为:采用模块式结构,特殊功能模块(如PID控制模块)增减方便。 [0003] Application of two types have advantages and disadvantages, general-purpose controller advantages: modular structure, easy special function modules (such as PID control module) increase or decrease. 不需要拆卸或更换控制器即可在其控制核心软件内增减特殊功能应用;缺点为:价格相比较专用控制器昂贵,不如专用型控制器是针对设备本身需要的接口设计的硬件。 Without disassembly or replacement of the controller to increase or decrease the special function application software which controls the core; disadvantage: the price expensive compared to a dedicated controller, as a dedicated controller is designed to interface hardware device itself requires. 浪费严重。 Waste. 专用型控制器优点为:性价比高,控制输入输出接口针对性强;缺点为:软件升级比较繁琐,需要专业人员操作。 Dedicated controller advantages: cost-effective, high-output interfaces targeted control input; disadvantage: software upgrades cumbersome, require professional operation.

发明内容 SUMMARY

[0004] 为克服现有变频空气压缩机的控制装置的上述不足,本发明提供一种软件升级简便、成本较低的变频空气压缩机的控制装置。 [0004] In order to overcome the above disadvantages of the conventional inverter control device of the air compressor, the present invention provides a control device for a simple software upgrade, the low cost inverter air compressor.

[0005] 本发明解决其技术问题的技术方案是:一种变频空气压缩机的控制装置,包括: [0005] The present invention solves the technical problem technical solution: A method of controlling an air compressor inverter apparatus, comprising:

一上位机,用于安装由VB程序编写的下载软件,该上位机具有采用MODBUS RTU协议传 A PC, for mounting VB prepared by downloading the software program, the PC has passed using MODBUS RTU protocol

送数据的串口; Send serial data;

一下位机,所述的下位机具有485接口,下位机通过485接口与所述上位机的串口通信连接,该下位机内嵌有用于初始化外设的BOOT应用程序。 Look-bit machine, the machine having a lower bit 485, connected to the lower serial communication with the host computer via the interface 485, the lower bits embedded BOOT unit initialized for peripheral applications.

[0006] 当系统上电时,先执行BOOT应用程序,初始化必要的外设,打开485接口等待接收上位机程序。 [0006] When the system is powered on, the BOOT first application initialization necessary peripherals, opening 485 waits for reception of the PC program. 如检测到更新程序命令则执行更新命令并在显示面板上显示当前状态。 The detected update command is executed and update command displays the current state on the display panel. 如等待一定时间还未检测到更新命令则跳转到原用户应用程序执行。 The wait for a certain time has not detected an update command to jump to the original user application execution.

[0007] 本发明的有益效果在于:下位机不需要操作人员做任何操作,自动对上位机操作做出回应,并在自身显示界面上显示当前状态;装置为非通用型控制器,成本较低。 [0007] Advantageous effects of the present invention: lower machine operator does not need to do any operation, automatic operation to respond to the host computer, and displays the current state on the display screen itself; means a non-general-purpose controller, low cost .
