CPU module of DDC intelligent hardware

Abstract

The invention provides a CPU module of DDC intelligent hardware. The CPU module is a plurality of modules of a micro control unit (MCU) with different numbers of I / Os, monitoring point interfaces of the CPU module is in direct connection with the I / Os of the MCU respectively, the plurality of I / Os of the MCU can be connected to such four types of monitoring points as an analog input AI monitoring point, a digital input DI monitoring point, an analog output AO monitoring point and a digital output DO monitoring point through the monitoring point interfaces or connected to any three types, or two types or one type of the four types of monitoring points; a plurality of power supply 1 interfaces and a plurality of power supply 2 interfaces of the CPU module are identical to power supply interfaces arranged in a plurality of peripheral analog input AI modules, a plurality of digital input DI modules, a plurality of analog output AO modules, a plurality of digital output DO modules and a plurality of modules with the monitoring point being single or the four types of monitoring points being arbitrarily combined in specification, and the power supply polarity is identical in sequence. The beneficial effects are that labor hours and materials of such links as procurement, production, sales, assembly, installation, operation and maintenance are greatly saved, professional skill requirements for the personnel are reduced, the monitoring points are convenient to be switched, the application is flexible, the practicability is high, and product standardization is carried out easily.

Description

technical field [0001] The invention relates to a CPU module of DDC intelligent hardware, which is commonly used in system processing of intelligent control of environment and equipment. Background technique [0002] Most of the existing DDC controllers have an integrated structure, such as figure 1 , 2 As shown, the monitoring points (ie AI / DI / AO / DO) and the microprocessor (MCU) are on a PCB, and the number of each monitoring point is mostly fixed; some are connected to the monitoring point through the communication interface . This results in a large number of programming addresses in the CPU module, a large amount of programs, and cumbersome programming. Also, the technology in ZL200910245186.6 cannot be promoted due to the large space occupied by a single monitoring point. Most of the existing DDCs have no human-machine interface or are not intelligent interfaces, such as Siemens Climatix product series, general series RWD68, RWD68 / CN, Honeywell UB local controller U...

AI Technical Summary

Problems solved by technology

This results in more programming addresses in the CPU module, a large amount of programs, and cumbersome programming.

Also, the technology in ZL200910245186.6 cannot be promoted because of the large space occupied by a single monitoring point

Most of the existing DDCs have no man-machine interface or intelligent interface, such as Siemens Climatix product series, general series RWD68, RWD68 / CN, Honeywell UB local controller UB1211CH, UB2204CH, UB2221CH, UB 4334SCH, Honeywell Excel 800 general-purpose controller, and Johnson FEC DDC controller, therefore, the existing DDC controller in the market consumes a lot of man-hours and materials in the actual application process, requires high professional personnel, and is not easy to standardize
