Detailed Description
The invention is further illustrated by the following examples, which are not intended to limit the scope of the invention.
Example 1
Referring to fig. 1, the present embodiment provides an IP address management method, where the IP address management method is applied to an industrial control system, the industrial control system includes a plug-in, and the method includes the following steps:
s1, receiving a first IP registration request sent by first equipment;
the first IP registration request is sent out when the first equipment is connected with the card; the first IP registration request comprises a physical address of the first device and a device type of the first device; the physical address of the first equipment is determined according to a preset dial on a dial switch on the clamping piece;
s2, generating a first IP address according to the first IP registration request, and allocating the first IP address to the first equipment;
and S3, storing the first corresponding relation of the first IP address, the physical address and the equipment type of the first equipment.
It should be noted that, in the actual use process, there are usually a plurality of card members, and each card member is connected to an external device.
In this embodiment, when the first device is connected to the card, the first device can obtain the preset dial of the dial switch on the card holder. The preset dial is used to indicate the physical address of the cartridge (in this case also the physical address of the first device). When first IP registration information including the geographic position and the device type and sent by the first device is received, a corresponding first IP address is allocated to the first device. After this, the first correspondence of the first IP address, the physical address and the device type of the first device may also be stored. Therefore, the device type and the IP address of the device on the card can be inquired according to the geographic position, or the device type and the physical address of the device can be inquired according to the IP address.
In the present embodiment, the device types may include an analog quantity output device, an analog quantity input device, a switching quantity output device, and a switching quantity input device. The devices and the card in this embodiment may be connected in a hot plug manner. The hot-plugged equipment can be replaced in a live-wire mode, and the equipment can directly and normally work as long as the equipment meets the conditions. When the equipment works, the control can be carried out according to the IP address and the equipment type.
In this embodiment, the first IP registration request may be transmitted through a DHCP protocol.
Referring to fig. 2, fig. 2 is a system for implementing the above embodiment. In the above embodiments, the first device may be various IO modules (i.e., a switching value output module, a switching value input module, an analog value output module, etc. in the figure). When the IO module is connected with the card (also referred to as a base in the figure), the type of the IO module is sent to the controller through the switch, and the controller assigns a corresponding address to the IO module. When a field device is connected to the base, the controller will assign the IP address of the field device to the address previously assigned by the IO device.
In this embodiment, when the controller needs to turn on the device a, the external device corresponding to the switching value output module outputs a power-on signal to the device a. When the device a is powered on, a power-on response signal is sent, and the device corresponding to the switching value input module receives the power-on response signal. It should be noted that, in the present embodiment, the different types of IO modules may send or receive different types of signals, and are not limited to the output and the input of the switching value.
In particular, the dial of the dial switch may include 8 bits, where the first 4 bits are used to represent the cabinet number and the second 4 bits are used to represent the interface number.
The first IP address of the first device is generated based on the cabinet number and the interface number.
In this embodiment, the number of the cabinet can be determined by the high and low bits, for example, the first four bits are 0001, which can represent the first cabinet. The serial number of the cabinet and the position of the cabinet can be stored in the upper computer or the controller in advance. For example, the first cabinet is located in room D of company A, district B, and district C.
In this embodiment, the interface refers to a portion of the cartridge to which the device can be connected. For example, if the first four digits of the dial number are 0001 and the last four digits are 0001, then the interface of # 0001 on # 0001 cabinet can be represented.
In one example of the above embodiment, the IP addresses may be assigned from 192.168.1.1 to 192.168.1.254. When the dial of the dial switch is 00010001 (binary to decimal is 17), the first IP address assigned to the first device may be 192.168.1.17. Of course, in the implementation process of this embodiment, the IP address of the controller may also be set, and the IP address of the controller may be 192.168.1.1-192.168.1.10. The first IP address needs to be selected among the remaining addresses.
Specifically, referring to fig. 3, the step of assigning the first IP address to the first device may include the following steps:
s4, acquiring a second IP registration request sent by second equipment;
the second IP registration request is sent by the second equipment when the second equipment is connected with the card after the first equipment is disconnected from the original card; the second IP registration request includes a device type of the second device;
s51, when the device type of the second device is inconsistent with the device type of the first device, generating a second IP address, and allocating the second IP address to the second device;
alternatively, referring to fig. 4, in another embodiment, steps S1 to S4 of this embodiment are all the same as those of the previous embodiment, except that step S51 is replaced by step S52.
S52, when the device type of the second device is consistent with that of the first device, a first IP address is allocated to the second device;
wherein the second IP address is any one of the idle IP addresses.
In this embodiment, when the second device is connected to the original card, the second device is assigned a second IP address when the device type of the second device is different from the device type of the previous first device.
Specifically, the step of assigning the second IP address to the second device further includes the steps of:
and updating the first corresponding relation into a second corresponding relation of the second IP address, the physical address and the device type of the second device.
In this embodiment, after the second device is assigned with the second IP address, the first relationship may be updated to a second corresponding relationship between the device type, the physical address, and the second IP address of the second device.
Specifically, the IP address management method may further include the steps of:
receiving fault information sent by first equipment when the first equipment is in fault, and responding to the fault information to generate repair information of the first equipment;
the repair information comprises the equipment type of the first equipment.
In this embodiment, when there is a device failure, the worker may know which device has failed in the first time by sending the repair information including the device type of the first device, so that the device of the same type as the first device is used to replace the original first device.
