Programming method, system and computer of DDC (Direct Digital Control) logic

Abstract

The invention provides programming method, system and computer of DDC (Direct Digital Control) logic, which are suitable for the fields of computers and air conditioners. The method comprises the following steps of: presetting a DDC function module, an input parameter of the function module and combined logic of the function module; receiving the function module selected by a user, and displayingan input parameter window; receiving the input parameter, and receiving the combined logic; determining a control logic code of the function module, adding the input parameter to a corresponding position of the control logic code, and determining the control logic code corresponding to the combined logic; combining the logic code of the function module and the control logic code corresponding to the combined logic to obtain the control logic code of the DDC; and downloading the control logical code of the DDC into an EEPROM (Electrically Erasable Programmable Read Only Memory) of the DDC. Thetechnical scheme provided by the invention has the advantages of high standard and higher programming efficiency.

Description

technical field [0001] The invention belongs to the field of air conditioning and energy, and in particular relates to a DDC control logic writing method, system and computer. Background technique [0002] Direct digital control (Direct Digital control, DDC) controller is a control device with simple structure and easy operation. It can be controlled by the interface switching device as the load changes, such as air-conditioning cold water circulation system, air-conditioning box frequency conversion automatic air volume adjustment And the frequency conversion control of the cooling tower cooling fan, etc., can make the air conditioning system run more efficiently. In this way, it not only brings great economic benefits to the property management, but also makes the system run under better working conditions, thereby extending The service life of the equipment and the purpose of providing a comfortable air-conditioning environment and energy saving. [0003] At present, the...
