Strong and weak current integrated monitoring and management system for building equipment

Abstract

The invention discloses a strong and weak current integrated monitoring management system for building equipment. The system comprises an execution unit, wherein the execution unit is internally provided with execution equipment and a monitoring element; the integrated control units are connected with the execution units in a one-to-one correspondence mode and used for receiving signals of the monitoring elements to control on-off and working states of the execution devices. The monitoring host platform is connected with the integrated control unit and is used for monitoring and actively controlling the operation of the integrated control unit and the execution unit. According to the integrated control device, the sampling circuit is connected with the monitoring element of the execution unit and used for collecting data and feeding back the data to the chip, the chip compares the data with preset data of the monitoring host platform after receiving the data, the switching state of the opening and closing switch is controlled, and strong current control is conducted on execution equipment; and the working state of execution equipment is adjusted through the output control circuit, weak current control is carried out, external components and wiring are greatly reduced, the system reliability is improved, the wiring failure rate is reduced, and the problem of interface coordination between strong current and weak current is solved.

Description

technical field [0001] The invention relates to the field of construction electromechanical technology, in particular to an integrated monitoring and management system for strong and weak currents of construction equipment. Background technique [0002] The building equipment monitoring system is an important part of the intelligent building system. It is a comprehensive intelligent system that centrally controls, manages and monitors building-related HVAC, water supply and drainage, electricity, lighting, elevators and other equipment. There is a chain relationship between various types of electromechanical equipment in the building, so perfect centralized and automated management is required. Establish a mechanical and electrical equipment management system to achieve comprehensive management, scheduling, monitoring, operation and control of mechanical and electrical equipment, and achieve the purpose of energy saving.

Problems solved by technology

[0003] But in the actual implementation process of the project, starting from the system design link, the cooperation between the weak current intelligent system major and the strong electrical and electrical major of the general building automation is basically out of touch. Since the traditional weak current DDC controller is a general-purpose product, It cannot be used directly in the three links of project design, construction commissioning, and post-maintenance. It needs additional professional point design planning, port definition, and secondary programming to be practically applied. The complicated process and high technical threshold lead to design institutes Basically do not participate in the construction drawing design of building automation control, and basically the manufacturers cooperate with the construction unit to complete the design in the later stage; at the same time, the lag in the design link and the disconnection of cooperation also lead to confusion in the construction and commissioning links, and it is impossible to effectively unify the strong and weak currents

[0004] At present, the building equipment monitoring system adopts the traditional strong and weak current separation method, and uses a separate control switch to control the strong and weak current parts. At the same time, a DDC output control module is set in the weak current part to control the action of the on-site actuator and the system platform. Therefore, a large number of external components and wiring are required, which greatly reduces the reliability of the system, increases the wiring failure rate, and increases the interface coordination between strong and weak currents.
