The data acquisition subsystem includes: fire monitoring subsystem, air conditioning monitoring subsystem, fresh air fan monitoring subsystem, water leakage monitoring subsystem, access control monitoring subsystem, video monitoring subsystem, infrared sensing anti-theft subsystem; The central control server determines whether the monitoring parameters collected by the data collection subsystem exceed the system preset value. If so, the display device pops up an alarm message, and the central control server sends a control instruction to the monitored device corresponding to the alarm message; The display device is used to display the indicator analysis data of the monitored equipment in the form of visual charts, and the visual icons include: equipment alarm distribution, alarm ranking, environmental curve, uninterruptible power supply UPS operation curve, temperature and humidity curve; The monitoring system is provided with an interface for docking with an energy consumption monitoring system, and the monitoring system sends data to the energy consumption monitoring system via a hypertext transfer protocol or a simple network management protocol.

[0021] The port smart energy consumption monitoring system of the disclosed embodiment processes the data collected by the data acquisition subsystem uniformly through the central control server. The central control server determines whether the monitoring parameters collected by the data acquisition subsystem exceed the system preset value. If so, the display device pops up an alarm message, and the central control server issues a control instruction to the monitored device corresponding to the alarm message; the display device is used to display the indicator analysis data of the monitored device in the form of a visual chart, and the visual icon includes: equipment alarm distribution, alarm ranking, environmental curve, uninterruptible power supply UPS operation curve, temperature and humidity curve. In this way, the port is monitored in real time and centralized, and intelligent perception, independent operation, digital image fusion, and remote operation and maintenance are realized. An overall system covering power, environment, video, security, fire protection, energy consumption, control, big data analysis, and management is built to realize real-time monitoring, pre-warning, in-process alarm, and post-event evidence collection. Safety management mode, to create an advanced and reliable smart port. It solves the problem of high cost caused by manual maintenance of traditional port equipment, and the problem of high port wiring cost and complex wiring caused by the use of wired sensor wiring in traditional ports.

[0022] The port smart energy consumption monitoring system meets the three levels of the Internet of Things (application layer, transmission layer, perception layer), and uses sensors and other technologies to enable information sensing devices to perceive the required information in real time. According to the agreed protocol (including but not limited to Modbus, TCP / IP, etc.), through possible network access methods (such as wireless LAN, wired network), the device is connected to the Internet for information exchange and communication, realizing ubiquitous links between devices and devices, and between devices and people, and realizing intelligent identification, tracking, monitoring and management of port equipment.

[0023] The data acquisition subsystem is interconnected with the equipment through industrial interfaces such as RS485, and collects real-time information such as power and environment, such as equipment energy consumption information, energy efficiency information, port environment information, video and other real-time information, and transmits it directly to the central control server to realize real-time monitoring, storage and output of data, and record alarm events. Managers can understand the port situation in real time by browsing Web pages or mobile devices, so as to grasp the port working status anytime and anywhere.

[0024] In one possible implementation, the central control server calculates the energy consumption index data of the port based on the monitoring parameters collected by the data acquisition subsystem, optimizes the energy-saving strategy based on the energy consumption index data, and adjusts the operating parameters of the equipment based on the optimized energy-saving strategy. The energy-saving strategy includes: power supply plan optimization, cooling method optimization, and operation mode optimization.

[0025] The cooling method optimization includes: using a control method of an air conditioning system, the method including: The real-time dynamic model of the system is set as follows (1): (1) in, represents the state of the air conditioning system at time t, represents the control input, represents process noise, A and B represent system matrices; Define the cost function J, which is used to balance the relationship between energy consumption and comfort; (2) Among them, Q and R represent weight matrices, which are used to balance energy efficiency and comfort; The optimal control strategy is obtained using a linear quadratic regulator: (3) (4) Where P represents the symmetric positive definite matrix obtained by solving the algebraic Riccati equation, and K represents the feedback gain; A and B are calculated based on the collected air-conditioning environment data. A and B reflect the response characteristics of the air-conditioning system to environmental changes. The air-conditioning system is controlled by adjusting u(t); The Riccati equation is as follows: (5).

[0026] Control the air conditioning system by adjusting u(t), including: The temperature and humidity data of the air-conditioning system are collected through the temperature and humidity sensors, and the air quality data collected by the air quality sensor are used to adjust the control input variable u(t), and the control input variable u(t) is transmitted to the air-conditioning system and the fresh air system.

[0027] For example, after setting the energy-saving strategies of all individual devices, the energy-saving strategies of individual devices are adjusted after big data calculation and analysis. Through continuous testing, the comprehensive energy-saving rate is improved, and finally the target energy-saving rate is approached or even reached. For example, improving the energy-saving rate requires long-term big data analysis training. The artificial intelligence AI algorithm is continuously optimized according to the long-term training results to achieve a target energy-saving rate. The working mode of each device when the target energy-saving rate is reached can be determined by the neural network model. Among them, the energy-saving rate is the result of the power consumption in the original working mode minus the power consumption in the energy-saving mode, divided by the power consumption in the original working mode.

[0028] In a possible implementation, the central control server predicts future energy consumption of equipment in the port based on historical monitoring parameters and historical energy consumption, generates an analysis report, and sends the analysis report to the mobile terminal.

[0029] In one possible implementation, the fire monitoring subsystem includes: a smoke sensor, a methane sensor, a flame sensor, a carbon monoxide sensor, and a first data collector. The smoke sensor is used to detect smoke in the port, the methane sensor is used to detect methane gas in the port, the flame sensor is used to detect flames in the port equipment room, and the carbon monoxide sensor is used to detect carbon monoxide in the port. The first data collector is used to obtain data collected by the smoke sensor, the methane sensor, the flame sensor, and the carbon monoxide sensor, and send the data to the gateway device.

[0030] For example, the status of smoke sensors in ports is monitored. Smoke sensors are installed on the ceiling of the port, and the output signals of the sensors are transmitted to the central control server through the data collector. In this way, when there is a fire, the monitoring system will immediately alarm and notify the port management personnel.

[0031] Implement remote centralized monitoring of the first data collector to monitor the fire situation in each area in real time. The system will automatically pop up an alarm prompt, remotely push the alarm message to the mobile terminal application of the operation and maintenance manager, and control the monitoring equipment to take pictures, which is conducive to quickly locating the port location of the alarm.

[0032] In one possible implementation, the air conditioning monitoring subsystem includes: an infrared remote controller, a temperature and humidity sensor, and a smart socket, wherein the infrared remote controller is used to control a cabinet air conditioner or a wall-mounted air conditioner, the temperature and humidity sensor is used to sense the temperature and humidity in the port, and the smart socket provides power for a humidifier or a dehumidifier; wherein the infrared remote controller, the temperature and humidity sensor, and the smart socket are controlled by the central control server, and the central control server sends temperature or humidity data to the mobile terminal.

[0033] For example, since the temperature collected by the air conditioner is only the situation in the surrounding area, high-precision temperature and humidity sensors are deployed in multiple corners of the room to collect the overall indoor temperature and humidity conditions and feed them back to the platform. The monitoring system collects data and performs statistical analysis, controls the infrared remote control and smart power strips / sockets to turn the air conditioner and dehumidifier / humidifier on or off, thereby adjusting the indoor temperature and humidity conditions.

[0034] The air conditioning monitoring subsystem also includes: multiple intelligent air conditioning panels, which are used to control the central air conditioning. The intelligent air conditioning panels are controlled by the central control server, and the intelligent air conditioning panels send the operating parameters of the central air conditioning to the central control server. The operating parameters include set temperature, wind speed, and working mode. For example, temperature and humidity sensors are deployed in multiple corners of the room to monitor temperature and humidity data in real time, and the data is transmitted back to the central controller of the monitoring system through the wireless communication protocol. Once the temperature exceeds the threshold, the intelligent air conditioning panel is instructed to control the central air conditioning to increase the wind speed in order to quickly reduce the temperature. The wind speed of the central air conditioning is controlled in real time. The platform adjusts the wind speed in real time based on the temperature data, and indoor temperature and humidity control can be achieved without manual control.

[0035] The fresh air fan monitoring subsystem includes: a second data collector, which is used to collect the operating status parameters of the fresh air fan. Since the port office area and equipment room are relatively sealed spaces, the internal and external air cannot circulate well. In order to ensure the health of internal staff, outdoor air must be extracted through fresh air / exhaust fans, and appropriate air exchange is carried out in a circulating manner after cleaning and filtering. It mainly monitors whether the operating status of the fresh air fan is normal and issues an alarm in time.

[0036] The precision air conditioner in the port equipment room provides constant temperature and humidity environment conditions for the port equipment room to ensure the good and stable operation of the port equipment. Therefore, it is urgent to monitor the precision air conditioner in the port equipment room. The precision air conditioner has an RS232 / RS485 communication interface. Through the data collector and the precision air conditioner system, the return air temperature, outlet air temperature, humidity, air conditioner operation status, fan operation status, compressor operation status and other parameters of the precision air conditioner can be monitored to realize the remote power on and off of the air conditioner. When the air conditioner is abnormal or exceeds the preset threshold of the system, the monitoring system can promptly inform the administrator through the Web terminal, APP, SMS and other methods.

[0037] For example, the port equipment room is mainly used to store servers, and the equipment has very strict requirements on the operating environment such as temperature and humidity, so temperature and humidity sensors should be installed to detect the temperature and humidity in the port and important equipment areas in real time. The integrated temperature and humidity sensor will transmit the detected temperature and humidity values ​​to the port intelligent energy control system platform in real time, and intuitively display them in graphical form on the platform interface. Once the temperature and humidity values ​​exceed the threshold, the system will automatically adjust and trigger an alarm to provide the best operating environment for the port equipment. In addition, the temperature and humidity values ​​of the port over a period of time can be intuitively displayed through historical curves to facilitate management personnel to view.

[0038] In a possible implementation, the video monitoring subsystem includes: a plurality of cameras, the cameras are installed at important monitoring points of the port, and the cameras transmit captured images to the central control server.

[0039] The port video surveillance capture system installs cameras at important locations inside the port, such as the port entrances and exits, above the cabinets, and at water leakage monitoring points. The transmission network can be the user's private network, the Internet, or wireless networks such as GPRS / CDMA / 3G / 4G. The captured images will be stored in the central control server.

[0040] In one possible implementation, the water leakage monitoring subsystem includes: a water leakage monitor and a third data collector. The water leakage monitor is installed around equipment with a risk of water leakage. The water leakage monitor transmits the detected signal to the gateway device through the third data collector and then reports it to the central control server. The central control server determines the water leakage location based on the location information of the water leakage detector and the image information collected by the video monitoring subsystem, and sends the water leakage alarm information and the water leakage location information to the mobile terminal.

[0041] The condensation water pipes of the precision air conditioners in the room may leak, or the air may condense into water droplets due to the low temperature of the air conditioners, which will threaten the equipment in the port. Install positioning leakage monitoring equipment near the water source that may cause leakage around the precision air conditioners. The leakage monitoring equipment can be a leakage monitoring rope. Once water leaks and touches the leakage monitoring rope, the induction rope transmits the signal to the gateway through the data collector and reports it to the port smart energy control system platform. At the same time, the video monitoring equipment is linked to accurately reflect the specific location of the leakage, and the relevant personnel are notified to eliminate it in time, and relevant alarm information is generated.

[0042] In a possible implementation, the access control monitoring subsystem includes: access control equipment, a fourth data collector, the fourth data collector is used to collect the port entry record, port exit record, and access control opening mode record of the access control equipment, the port entry record includes the port entry time record, the port exit record includes the port exit time record, and the access control opening mode record includes fingerprint opening, password opening, face recognition opening, and key opening. The port entry record, port exit record, and access control opening mode record of the access control equipment can be queried after being saved, so that the switch status of the monitored door is monitored and the port safety is guaranteed.

[0043] The infrared sensing anti-theft subsystem includes: multiple infrared human body sensing sensors, which turn on the sensing function within a preset time period. When a person is sensed, an alarm message is sent to the central control server through the gateway device, and the central control server sends the alarm message to the mobile terminal.

[0044] The infrared human body sensing sensor can conduct infrared anti-theft for the overall situation of the port in an all-round way. The monitoring time can be set, for example, the monitoring time can be from 22:00 to 8:00 the next day. During the monitoring time, if someone illegally invades, the display interface and sound output device of the monitoring system will give sound and light prompts for alarm information, and notify the port management personnel of the alarm information through SMS, APP, etc.

[0045] In one possible implementation, the power monitoring subsystem includes: a power meter, a fifth data collector, and the data collector is used to collect parameters of the power meter. The parameters of the power meter include: phase voltage, phase current, frequency, active power, reactive power, and power consumption of the three-phase AC power supply.

[0046] For example, the electricity meter collects the parameters of the port distribution box, and sends the collected data to the fifth data collector through the RS485 communication protocol; the fifth data collector sends the data to the gateway device through wired or wireless communication, and the gateway device sends the data to the central control server.

[0047] The quality of the power supply of the mains power supply bus of the port power distribution cabinet will directly affect the safety of the equipment in the port, so it is necessary to use an intelligent power monitor to monitor the mains power supply parameters of the port machine room. By monitoring the phase voltage, phase current, frequency, active power, reactive power and other parameters of the three-phase power supply of the mains, the port administrator can check in real time whether the power supply quality is intact. When the parameters are abnormal, the linkage alarm is triggered to notify the administrator in time.

[0048] In one possible implementation, an uninterruptible power supply can be used as a backup power supply to power the equipment in the port. By connecting the fifth data collector to the communication interface of the uninterruptible power supply, the Internet of Things platform can obtain information including input electrical parameters, output electrical parameters, battery parameters, and operating status, thereby realizing real-time monitoring of the uninterruptible power supply. When an abnormality occurs in the operating parameters, an alarm can be sent to the mobile terminal, such as sending a text message or an APP pop-up window to alert the administrator.

[0049] In a possible implementation, the central control server performs statistical analysis based on the data collected by the electricity meter and converts the power consumption data into a statistical report, which can intuitively show the daily energy consumption, abnormal energy consumption time period, energy consumption pattern and other data. The report time range supports annual, monthly and daily power consumption statistics, and the report space range supports company, floor, room and point power consumption statistics. It can estimate the energy consumption of the port and find potential power-consuming equipment to facilitate energy conservation and emission reduction.
