example 1

[0045] Example 1 Low-voltage detection system

[0046] Such as figure 2 As shown, because the low-voltage system does not require high sensor resistance, the insulated host 2-1 is selected. Install the insulated main engine sensor 2-1 in front of the diesel generator, the motor and the DC isolated power supply to detect whether there is leakage in the cable. Such as figure 1 The shown insulated host transmits the condition of the cable to the PLC controller located in the electrical room 1-4, and the controller transmits the data signal to FBOX1-5. After simple numerical calculation, the signal is transmitted to the cloud server 1-6. After After the system data is processed, it will be passed to the APP end and WEB end 1-9. At the same time, the cloud server uses RCMS architecture 1-7, and the system can read data from the database at any time, thereby realizing real-time monitoring and monitoring.

[0047] Example 2 High voltage detection system

[0048] Such as image 3 As shown, because the high-voltage system requires high sensor resistance, select the high-voltage insulating sensor 5-1, install it in front of the switch cabinet 5-3, and install the high-voltage insulating sensor 5-2 at the turntable 5-7. A high-voltage insulation sensor 5-4 is installed on the cable in front of the switch cabinet 5-3. Install a high voltage insulation sensor before the transformer 5-5. The sensor transmits the data signal to the PLC controller in the electrical room. Such as figure 1 The shown PLC controller transmits the signal to the FBOX gateway 1-5, and after a simple calculation, transmits the data signal to the cloud server 1-6, and the cloud server reads real-time data from the database through the RCMS architecture 1-7, Realize the real-time transmission of data, and finally transmit all the data to the WEB and APP terminals 1-9.

Abstract

As a wharf equipment system is in a severe environment with high salt mist humidity, equipment mainly has high power, equipment aging is easy to occur, and meanwhile, technical means for supervision are lacked so that problems of electric leakage and safety of a whole monitoring system are easily caused. In the invention, a cloud service technology is applied to an insulation monitoring system; analog quantity data signals of a low-voltage detection system and a high-voltage detection system enter a data acquisition conversion device, and then enter a PLC control system; trolley cabinet monitoring and electrical room monitoring are included; through a WIFI or 4G architecture, the PLC transmits the data to a gateway FBOX, and simple data processing is performed; and finally, the data is uploaded to a cloud server, the cloud server can read the data from a RCMS database through a RCMS architecture, historical playback and operation statistics functions are realized, and finally all the data are transmitted to a WEB terminal and an APP terminal so that an aging position of an insulation system can be monitored in real time, and time, labor and economic cost is reduced.

Description

technical field [0001] The patent of the present invention mainly relates to a kind of industrial control monitoring system, especially for port insulation monitoring equipment. Background technique [0002] The port terminal equipment system is in a harsh environment such as high salt spray and humidity. The equipment is mainly high-power, and it is easy to accelerate the aging of equipment and cables after long-term operation. These problems will lead to safety problems such as leakage, shutdown, and fire. Therefore, the insulation monitoring system is very important for the entire terminal system, not only to ensure the safety of the equipment in harsh environments, but also to improve the working efficiency of the entire terminal equipment. Ordinary insulation testing equipment systems often only monitor the motors and circuit circuits on site, such as auxiliary circuits, lighting circuits, and control circuits, so as to report the insulation status of the power system i...
