The specific technical process of the application is as follows:
(1) And designing a complete flow of on-line intelligent monitoring and analysis control of the energy of workshop equipment.
(2) And constructing a hardware architecture system. Each device to be monitored is provided with an EMU4-HD electric energy module and a pulse module, and a CC-Link communication module is extended to be used as a communication slave station. A server module is adopted as a communication master station.
(3) The communication master station sets the number of communication slave stations, sets parameters such as power standard consumption data and pulse standard consumption data for each machine of each communication slave station, and sets acquisition frequency and storage time in the communication master station software.

(5) And feedback controlling the open state of each machine.
The master station firstly collects values at a certain frequency through the server, automatically calculates and predicts the data of the electric energy value, the water energy, the natural gas quantity and the like consumed in the process of the equipment machine in the time period, and compares the data with the standard data of the equipment in the time period when the equipment works normally. Once the abnormal high energy consumption value occurs in the corresponding time period or under the same working condition of starting, the server feeds back the output I/O signal to control the starting state of each machine and can be connected with the alarm device at the same time.
Two common feedback control modes of the machine connection structure (other connection structures can be decomposed into two types of connection structures and then reference is made to the execution):
I. feedback control mode of the tandem machine:
machine 1 and machine 2 are connected in series (referred to as a process series), and communication slave station Q collects each consumption data of machine 1 and machine 2, respectively, and transmits each consumption data to server S; the server S is connected to the Ethernet E, and the host computer, the employee computer and the output equipment are respectively connected to the Ethernet E.
The host computer sends a request to the server S through the feedback of the host PLC, the server S sends an instruction to the PLC of the machine 1, and the PLC of the machine 1 controls the start and stop of the machine 1; the server S issues instructions to the PLC of the machine 2, the PLC of the machine 2 controlling the start and stop of the machine 2.
If the sum of the electric energy, the water quantity or the air quantity consumed by each machine does not have large fluctuation, each machine is not stopped;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, the data of the machine 2 has fluctuation 2, and the difference value between the sum and the fluctuation 2 does not have fluctuation, the machine 2 is stopped for maintenance, and the machine 1 of the previous working procedure is not stopped;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, and the data of the machine 1 has fluctuation 1, the machine 1 is stopped for maintenance, and the machine 2 in the subsequent process is also stopped and maintenance is not needed.
And II, feedback control mode of parallel machine:
machine 2 and machine 3 are connected in parallel (refer to parallel working procedures), and communication slave station Q collects each consumption data of machine 2 and machine 3 respectively and transmits the consumption data to server S; the server S is connected to the Ethernet E, and the host computer, the employee computer and the output equipment are respectively connected to the Ethernet E.
The host computer sends a request to the server S through the feedback of the host PLC, the server S sends an instruction to the PLC of the machine 2, and the PLC of the machine 2 controls the start and stop of the machine 2; the server S issues instructions to the PLC of the machine 3, the PLC of the machine 3 controlling the start and stop of the machine 3.
If the sum of the electric energy, the water quantity or the air quantity consumed by each machine does not have large fluctuation, each machine is not stopped;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, the data of the machine 2 has fluctuation 2, and the difference value between the sum and the fluctuation 2 does not have fluctuation, the machine 2 is stopped for maintenance, and the machine 3 is not stopped;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, the data of the machine 3 has fluctuation 3, and the difference value between the sum and the fluctuation 3 does not have fluctuation, the machine 3 is stopped for maintenance, and the machine 2 is not stopped;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, the data of the machine 2 has fluctuation 2, and the difference value between the sum and the fluctuation 2 has fluctuation, the machine 2 is stopped for maintenance and the machine 3 is stopped for maintenance;
if the sum of the electric energy, the water quantity or the air quantity consumed by each machine has large fluctuation, the data of the machine 3 has fluctuation 3, and the difference value between the sum and the fluctuation 3 has fluctuation, the machine 3 is shut down for maintenance and the machine 2 is shut down for maintenance.
Two feedback control modes of abnormal machine data (cooling water and natural gas):
as the cooling water is used for cooling, the water consumption is more, the cooling effect is good, the water consumption is less, the water flow is insufficient, the temperature is easily raised, and the danger is generated.
So that when the water consumption data of a certain machine is large, emergency stop is not needed (overhaul is carried out after the whole production line is stopped, so that water resource waste is prevented); the consumption of cooling water is less, and the emergency shutdown maintenance is necessary.
Because natural gas is used by combustion, less consumption means that the heating amount is small, the system is safe from the temperature rising angle, more consumption means that the heating amount is large, and the system is unsafe from the temperature rising angle.
So that the natural gas consumption data of a certain machine is smaller without emergency stop (overhauling after the whole production line is stopped, and preventing defective products from occurring due to insufficient heat); emergency shut down for maintenance is necessary if the fuel consumption of a machine is high.
The beneficial effects are that:
the invention can respectively monitor each machine independent of each other, energy signals such as electric energy, cooling water, steam, natural gas and the like can be respectively collected, and the feedback control can adopt an intelligent control mode with fewer control circuits and more accurate control.
The production efficiency of the equipment in stable operation can be known through the management of the original units, and the production efficiency of the same equipment/production line in different time periods or between different equipment/production lines can be compared and analyzed.
The project can realize the function of network energy meter reading, and more importantly, the project has the function of analyzing loopholes in production management, solves the problem of energy meter reading work in a production workshop, and saves time and labor. The factory can predict the trend of the total consumption value in the future; the equipment department can also pre-judge the fault precursor of the equipment in early stage through the abnormal power consumption data value of the equipment, and timely make maintenance and maintenance measures. All energy sources such as electric power, steam, natural gas, water and the like are spirally upgraded and improved, and the method is an important development direction of 4.0 of energy conservation and intelligent factories in the future.
