Detailed Description
The technical scheme of the application is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1: as shown in FIG. 1, the intelligent monitoring system for the start-up and shutdown of the rotary kiln based on the sniffing technology comprises a monitoring equipment adding statistical module, a sniffing module, a data packet analysis module, a shutdown rule determination module and a start-up and shutdown judgment module.
The monitoring equipment adding statistical module is used for adding the monitoring equipment on the data link and the network link related to the rotary kiln start-stop monitoring to the monitoring equipment list. The monitoring devices include servers, personal computers, industrial data acquisition gateways, switches, routers, gateways, and the like. And each monitoring device is provided with corresponding identification information, wherein the identification information comprises a monitoring device IP address, a monitoring device physical address, a network port, a gateway IP address to which a monitoring device IP network segment belongs, a router IP address to which a monitoring device IP network segment belongs, a next hop address of a router to which the monitoring device IP network segment belongs, a monitoring device name, a monitoring device application, a monitoring device process name and a monitoring device port number.
And the sniffing module is used for sniffing the monitoring equipment in the monitoring equipment list according to the identification information and through sniffing instructions so as to determine the state of the monitoring equipment. The sniffing module needs to sniff three layers in sequence, as shown in fig. 2, the first layer sniffs the data link layer through the first sniffing unit, the second layer sniffs the network link layer through the second sniffing unit, and the third layer sniffs the application layer through the third sniffing unit, specifically,
the first sniffing unit sniffs the monitoring equipment in the monitoring equipment list in a data link layer through a first sniffing instruction, and obtains first sniffing information of the monitoring equipment; the identification information includes first sniffing reference information; when the first sniffing information of the monitoring device is the same as the first sniffing reference information corresponding to the monitoring device, the first sniffing unit sets the state of the monitoring device as available, otherwise, sets the state of the monitoring device as unavailable. The first sniffing information is a sniffing physical address of the monitoring device obtained by sniffing the monitoring device by the data link layer by the first sniffing unit, and the first sniffing reference information is the monitoring device physical address in the identification information stored in the monitoring device list by the monitoring device.
Specifically, if the monitoring devices all belong to the same network segment, the first sniffing unit sequentially initiates sniffing to the monitoring devices in the monitoring device list according to a first sniffing instruction of 'arosniffer monitoring device IP address' so as to obtain sniffing physical addresses of the monitoring devices; if the monitoring devices do not belong to the same network segment, the first sniffing unit sequentially initiates sniffing to the monitoring devices in the monitoring device list according to a first sniffing instruction 'an IP address of a gateway IP address monitoring device to which the IP network segment of the monitoring device belongs' so as to obtain sniffing physical addresses of the monitoring devices. The first sniffing unit compares the sniffing physical address of the monitoring equipment with the physical address of the corresponding monitoring equipment in the monitoring equipment list, and sets the state of the corresponding monitoring equipment as 'equipment available' when the sniffing physical address of the monitoring equipment is identical with the physical address of the corresponding monitoring equipment in the monitoring equipment list; when the sniffing physical address of the monitoring device is different from the corresponding monitoring device physical address in the monitoring device list, setting the state of the corresponding monitoring device as 'device unavailable'.
And the second sniffing unit sniffs the monitoring equipment with the available state of the equipment in the monitoring equipment list through a second sniffing instruction, and when the monitoring equipment has the condition that the network connection is overtime or the monitoring equipment cannot be connected, the second sniffing unit sets the state corresponding to the monitoring equipment as the condition that the equipment cannot be connected.
Specifically, the second sniffing unit sniffs network connectivity of the monitoring devices with the states of "available devices" in the monitoring device list according to the second sniffing instruction "ping the IP address of the monitoring device", if connection timeout or connection failure occurs in ping, the second sniffing unit changes the state of the corresponding monitoring device in the monitoring device list into "unable connection of the device", otherwise, the state of the corresponding monitoring device is still "available device".
And the third sniffing unit sniffs the monitoring equipment with the available equipment state in the monitoring equipment list through a third sniffing instruction, and when the port of the monitoring equipment has overtime network connection or can not be connected with the network, the third sniffing unit sets the state corresponding to the monitoring equipment as the equipment port can not be connected with the monitoring equipment.
Specifically, the third sniffing unit sniffs the network connectivity of the ports of the monitoring devices with the status of "available devices" in the monitoring device list according to a third sniffing instruction "telnet monitoring device IP address monitoring device port number", if telnet has connection timeout or cannot connect, the third sniffing unit changes the status of the corresponding monitoring device in the monitoring device list into "device port cannot connect", otherwise, the status of the corresponding monitoring device is still "available devices".
Finally, the sniffing module determines that the state of each monitoring device in the monitoring device list is "available for the device" or "unavailable for the device" or "incapable of being connected to the device port".
The data packet analysis module is used for acquiring TCP/IP data packets between monitoring equipment with available states of equipment and a rotary kiln correspondingly connected with the monitoring equipment in the monitoring equipment list, analyzing the data packets, and if the data packets do not meet the analysis requirements of the data packets, changing the states of the corresponding monitoring equipment. The data packet analysis module is shown in fig. 3, and includes a first data packet analysis unit, a second data packet analysis unit and a third data packet analysis unit.
For example, the IP address of a certain rotary kiln is 172.16.8.19, the internet access is "eth10", and the IP address of a monitoring device connected to the rotary kiln is 172.16.8.20.
The first data packet parsing unit is configured to obtain a TCP data request packet (which may be automatically obtained by an existing software program) sent by the rotary kiln (IP address is 172.16.8.19) to a monitoring device (IP address is 172.16.8.20) that is connected to the rotary kiln and has a status that is available to the device, parse the data request packet to obtain SYN and SEQ, if syn=1 and seq=x, continue parsing downwards, and if the data request packet does not meet the parsing requirement of the data request packet, set the status that corresponds to the monitoring device to be unavailable to the application program.
The second data packet parsing unit is configured to obtain a first data response packet (which may be automatically obtained by an existing software program) corresponding to the monitoring device (IP address is 172.16.8.20) and sent back to the rotary kiln (IP address is 172.16.8.19), parse the first data response packet to obtain SYN, ASK and SEQ, parse the first data response packet downwards if syn=1, ack=x+1 and seq=y, and set a state corresponding to the monitoring device as unavailable to an application program if the first data response packet does not meet a parsing requirement of the first data response packet.
The third data packet parsing unit is configured to obtain a second data response packet (which may be automatically obtained by an existing software program) sent back to the corresponding monitoring device (IP address is 172.16.8.19) by the rotary kiln (IP address is 172.16.8.20), parse the second data response packet to obtain SYN, ASK, and SEQ, parse the second data response packet downwards if ack=y+1 and seq=z, and set the state corresponding to the monitoring device as unavailable for the application if the second data response packet does not meet the parsing requirement of the second data response packet.
Finally, the state of each monitoring device in the monitoring device list is determined to be "available device" or "unavailable device port" or "unavailable application" through the data packet analysis module.
The shutdown rule determining module is used for setting a shutdown rule of the rotary kiln in a shutdown state, and the shutdown rule can be set according to expert experience. The shutdown rule determining module comprises a kiln rotating speed preset unit, a high-temperature fan temperature preset unit and a duration setting unit.
The kiln rotating speed presetting unit is used for setting a kiln rotating speed threshold value of the rotary kiln in a shutdown state, and when the kiln rotating speed of the rotary kiln is lower than 10r/h, the rotary kiln is possibly in the shutdown state. The high-temperature fan temperature preset unit is used for setting a high-temperature fan temperature threshold value of the rotary kiln in a shutdown state, and when the high-temperature fan temperature of the rotary kiln is less than 800 ℃, the rotary kiln is possibly in the shutdown state. The duration setting unit is used for setting a duration threshold value of the rotary kiln in a stop state, and the duration threshold value can be 5 minutes. In this embodiment, when the kiln rotation speed of the rotary kiln is lower than 10r/h, the temperature of the high-temperature fan is lower than 800 ℃ and the duration time is longer than 5 minutes, the rotary kiln is considered to be in a shutdown state currently.
The start-stop judging module is used for acquiring monitoring data of the monitoring equipment, which is available for the equipment, in the monitoring equipment list, and determining the operation state of the corresponding rotary kiln according to the monitoring data and the stop rule. The start-stop judging module comprises a rotary kiln stop judging unit, a rotary kiln operation judging unit and a rotary kiln off-line judging unit.
The rotary kiln stopping judging unit is used for acquiring monitoring data of the rotary kiln by the monitoring equipment with the available equipment in the monitoring equipment list, and judging that the corresponding rotary kiln is in a stopping state when the monitoring data meets the stopping rule (the kiln rotating speed of the rotary kiln is lower than 10r/h, the temperature of the high-temperature fan is lower than 800 ℃ and the duration time is longer than 5 minutes).
The rotary kiln operation judging unit is used for acquiring monitoring data of the rotary kiln by the monitoring equipment with the available equipment in the monitoring equipment list, and judging that the corresponding rotary kiln is in an operation state when the monitoring data does not meet the shutdown rule (the kiln rotating speed of the rotary kiln is not lower than 10r/h or the temperature of the high-temperature fan is not lower than 800 ℃, or the duration of the condition that the kiln rotating speed of the rotary kiln is lower than 10r/h and the temperature of the high-temperature fan is lower than 800 ℃ is less than 5 minutes).
The rotary kiln offline judging unit is configured to judge that a rotary kiln is offline when a monitoring device in a monitoring device list, which is in a state that a device is available, cannot judge that a certain rotary kiln is in a shutdown state or in an operation state (for example, the monitoring device connected with the rotary kiln is in a state that the device is unavailable, the device is not connected, the device port is not connected, or an application program is unavailable).
According to the intelligent monitoring system for the start-up and stop of the rotary kiln, the monitoring equipment on the data link and the network link related to the start-up and stop monitoring of the rotary kiln can be added into the monitoring equipment list through the monitoring equipment adding statistical module, the states of the monitoring equipment in the monitoring equipment list can be judged through the sniffing module and the data packet analyzing module to obtain the monitoring equipment with the states being available for the equipment, the running states of all rotary kilns can be judged through the monitoring equipment with the states being available for the equipment and the preset start-up and stop rules, and therefore misjudgment rate of the running states of the rotary kiln is effectively reduced, and accuracy of the start-up and stop state monitoring of the rotary kiln is improved.
Example 2: as shown in fig. 1, a rotary kiln start-stop intelligent monitoring method based on sniffing technology comprises the following steps,
