At present, industrial Ethernet is established in many coal mines in China and is used for monitoring underground coal mining equipment and underground environmental parameters; but mainly adopts a mixed network mode of hundred mega and giga (hundred mega downlink and giga uplink group ring).
The disadvantages of the existing underground Ethernet switch are mainly reflected in the following points:
the transmission rate is not high, mostly concentrated on 100 mega port communication, and generally only 2-3 fixed upstream gigabit ring ports.
Data exchange is mainly in a data link layer, with the development of the underground communication monitoring technology and the increase of equipment, the data volume to be transmitted is also increased rapidly, and the traditional two-layer forwarding technology cannot meet the requirements of modern underground communication.
The underground intrinsic safety power supply has definite limit on output power (GB3836.4 intrinsic safety explosion-proof standard). Typically 12V/1.2A or 18V/900mA, this power requirement limits the use of most common high-power tera-layer switches downhole.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention relates to a high-power mining intrinsic safety type trillion three-layer switch, in particular to a high-power multi-optical-port intrinsic safety type trillion three-layer switch for working condition information transmission of underground coal mine electromechanical equipment.
The following detailed description of specific implementations of the present invention is provided in conjunction with specific embodiments:
as shown in fig. 1 and fig. 2, an intrinsically safe trillion layer switch for high-power mines includes:
the power supply comprises a plurality of isolation power supplies (an isolation power supply 1 and an isolation power supply 2 … … isolation power supply N), a power supply detection circuit, a current control circuit, a tera switching circuit and a plurality of power consumption groups (a power consumption group 1 … … power consumption group N), wherein adjacent isolation power supplies in the isolation power supplies are connected, the isolation power supplies are respectively connected with the power supply detection circuit, the power supply detection circuit is respectively connected with the current control circuit and the tera switching circuit, the current control circuit is connected with the tera switching circuit, and the current control circuit is respectively connected with the power consumption groups;
the power detection circuit detects whether each isolation power supply works normally:
if the isolated power supply works normally, outputting normal information of the isolated power supply, communicating one isolated power supply with the tera exchange circuit through the power supply detection circuit, and carrying out power-on operation on the tera exchange circuit; after the power-on initialization of the tera switching circuit is completed, the power supply detection circuit and the current control circuit respectively communicate the remaining normally working isolated power supplies with the corresponding multiple power consumption groups, and power is sequentially supplied to each power consumption group of the multiple power consumption groups; after detecting that the power consumption group completes the power-on operation, the trillion switching circuit initializes the power consumption group and starts a switching forwarding function after the initialization is completed;
if a certain isolated power supply does not work, outputting abnormal information of the isolated power supply, and not powering on a corresponding ten-gigabit switching circuit or a power consumption group of the isolated power supply.
The high-power mining intrinsic safety type trilevel ten-gigabit switch is characterized in that an isolation power supply is communicated with a trilevel ten-gigabit switching circuit through a circuit switch in a power supply detection circuit, and the trilevel ten-gigabit switching circuit is electrified.
The intrinsic safety type ten-gigabit three-layer switch for the high-power mine further comprises: the CPU is a processor internally arranged in the ten-gigabit switching circuit or an external processor, the CPU is respectively connected with the power supply detection circuit and the current control circuit, the power supply detection circuit detects whether each isolated power supply works normally or not and transmits the information to the CPU, if the isolated power supply does not work, the CPU is informed that the isolated power supply in the path is abnormal, and if the isolated power supply works normally, the CPU is informed that the isolated power supply in the path is normal; the CPU controls the power supply detection circuit to power on or not to power on the tera switching circuit according to the received normal and abnormal information of the isolation power supply, and controls the current control circuit to power on or not to power on each power consumption group according to the received normal and abnormal information of the isolation power supply.
The isolated power supply which normally works means that the power supply with normal output is detected by the power supply detection circuit. The CPU needs to know which power consumption groups can be normally powered through the power detection circuit. For example: when a power consumption group such as the SFP cannot be normally powered on due to power supply abnormality, the CPU needs to notify a user, where the power consumption group functions abnormally. If some power supply is abnormal, the CPU can not supply power to the power consumption group through the current control circuit.
The isolated power supplies are independent power supplies, and have no relationship with each other except for the power-on timing requirement.
The power supply detection circuit is only responsible for detecting whether the isolation power supply works normally or not, and transmitting the information to the CPU, and if the isolation power supply does not work, informing the CPU that the isolation power supply is abnormal. If the isolated power supply is normal, the power consumption group is supplied with power through the current control circuit. Similar to one responsible for detecting and monitoring, the other responsible for distributing power to the lower power consumption units, that is, the action of turning on the power consumption groups is the work of the current control circuit, and how to know which power consumption group is turned on is the work of the power detection circuit.
The multi-path isolation power supply sequentially powers the tera switch circuit and the power consumption group, thereby reducing the influence of the system starting impact current on the intrinsic safety power supply to the maximum extent and ensuring that the system meets the intrinsic safety design requirement.
The specific principle is as follows:
1. the multi-path intrinsic safety isolation power supplies 1-N are sequentially connected to the tera exchange circuit and a plurality of power consumption groups, and the power consumption groups comprise but are not limited to one or more power consumption device units such as an optical module and an Ethernet phy chip.
2. When the power detection circuit detects that the isolation power supply is connected to the power consumption group, the isolation power supply is turned on to power on the ten-gigabit switching circuit, and the detection circuit comprises but is not limited to a MOS (metal oxide semiconductor) tube, an optical coupler and other switching devices.
3. After the power-on of the tera switching circuit is completed, the processor controls the current control circuit, for example, the IO pin drives the MOS switches to sequentially power on the power consumption group.
4. After detecting that the power consumption group completes the power-on operation, the tera switching circuit initializes the power consumption group, and starts a switching forwarding function after the initialization is completed.
5. The tera switch circuit comprises a processor unit, a tera switch chip, and a start storage computing chip and a POWER supply circuit which are necessary for the processor unit, as shown in fig. 2, the tera switch circuit comprises a tera switch chip, a processor unit, a CLK (clock), an SDRAM (memory), a FLASH memory, a RESET and a CORE POWER, wherein the RESET is used for providing the RESET function of the processor unit and the tera switch chip, the CLK is used for providing a timing function, the SDRAM and the FLASH are used for providing a storage function, the CORE POWER is used for supplying POWER to the tera switch chip and the processor unit, the tera switch chip is used for a data exchange transmission function, and the processor unit is used for a data processing function.
The invention uses multi-path isolation power supply to supply power to the system, and the power-on management and control are carried out on the tera exchange circuit and the power consumption group unit, so that the system meets the intrinsic safety design requirement. A step-by-step power-on technology is used for conducting step-by-step power-on a plurality of power consumption devices after pipe control, and the influence of impact current on an intrinsic safety power supply is effectively reduced. After the initialization of the tera exchange circuit is completed, power is supplied to the power consumption group units such as the SFP. The power-on method of sequentially turning on the power consumption groups only after the power-on of the processor is completed in the intrinsic safety design belongs to the protection scope of the invention, and includes but is not limited to hardware delay start, I0 step start and the like.
The above description is only exemplary of the present invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
