Embodiment 1

[0024] As shown in Figure 4, it is the connection between the cooling water pump control device 1 and the frequency converter 2 that drives the cooling water pump. The DB-9 connector 121 and the 9-core cable 201 are used for connection. Since the inverter is not equipped with a DB-9 connector (or the equipped DB-9 connector is only used for RS485 bus connection), a DB-9 connection conversion box 31 is added to the inverter side. The switch control 281, running state 282, running frequency control 283, running frequency feedback 284, fault status signal 285, and common terminal 286 of the frequency converter are led out and connected to the corresponding terminals of the frequency converter. 121a is a DB-9 type socket.

Embodiment 2

[0026] As shown in Figure 5, there are 54 information connections between an energy-saving control device and its relay device. In the past, it was necessary to connect 54 pairs of connectors and lay 54 cables. The present invention completes all connections with a 68-pin SCSI cable. 151 is a SCSI plug, and 202 is a 68-core flat cable.

Abstract

This invention provides a connecting method among devices in a building energy-save control system characterizing in applying standard plugs and sockets and multi-core cables between any two devices in the system. In order to implement this invention, standardized connection can be realized to the existent product devices without standard sockets by connection conversion boxes provided by this invention, and the output of the box includes a standard multi-core socket corresponding to standard plugs and the input includes connection end of leading out wire corresponding to the non-standard connection to be connected with the standard cable by the conversion box.

Description

technical field [0001] The invention relates to a connection between a control device of a building equipment energy-saving control system and controlled equipment, in particular to a method for standardized interconnection between equipment to meet mass production, transportation and storage of products. Background technique [0002] In modern buildings, energy consumption of heating, ventilation and air conditioning (HVAC) energy-saving control systems, lighting systems, elevators and other equipment usually accounts for about 80% of building energy consumption. In recent years, various equipment energy-saving control information systems and drive equipment such as frequency converters and contactors have emerged. These driving equipment and controlled equipment (such as motors, etc.) are usually high-power, high-current electrical equipment, but the interconnection between them and the energy-saving control equipment is a small current control signal. [0003] Since such...
