The present invention provides a network flow detection method, and comprises the following steps: a) adopting a flow control system to calculate the average rate of protocols according to the historical information of the protocol of the data packet and the information carried by the data packet; b) judging whether the data packet of the protocol should be controlled according to the average rate of protocols, which is calculated in the step a); and c) controlling the data packet which satisfies the control condition. Compared with the prior art, the method has the following advantages: the rate estimation algorithm based on the historical time window is adopted to accurately calculate the rate of the current protocol flow; the flexible and convenient configuration can be used for simultaneously controlling a plurality of protocols which are combined freely; the efficiency of the system is improved; only the protocol to be controlled needs processing, while others need no processing;the bypass type access brings convenience and can not form network bottlenecks; the system is simple and can be easily realized; and the system can achieve the accurate flow control.

This manual provides an outreach monitoring method and device, wherein the method includes: sending an intranet access request to an intranet detection device; receiving the access request result and detection script returned by the intranet detection device, and the access request result is the After the intranet detection device forwards the intranet access request to the intranet server, the request result returned by the intranet server; displays the access request result, and according to the external network server preset in the detection script address, sending an external network access request to the external network server; if the external network access request responds successfully, sending a blocking request to the internal network detection device, so that the internal network detection device blocks the internal network The connection between the terminal and the intranet server. To promptly block the connection between the offending intranet terminal and the intranet server.

The invention belongs to the technical field of gas springs, in particular to a balanced gas spring. The balanced gas spring includes a cylinder, a front seal, a rear seal, a piston and a piston rod. The front seal and the rear seal are respectively located at both ends of the cylinder, and the front seal is arranged on the piston rod; On the piston rod, and the end of the piston rod passing through the piston is threadedly connected with a nut. The middle part of the outer peripheral surface of the piston is provided with an outer ring groove. Groove; the present invention can quickly adjust the working spring without disassembling the gas spring, the adjustment efficiency is high, and the process is convenient.

The invention relates to a contact system with a high-voltage direct-current arc protection structure, comprising a ceramic seat, two static contacts, a movable contact and a transmission rod. The static contact is installed on the ceramic seat, and the movable contact is respectively in contact with the two static contacts. One end of the transmission rod is fixedly connected with the movable contact, and the other end is used for receiving power from the electromagnetic system and driving the movable contact to reciprocate linearly; The ceramic seat is provided with a protective structure for cutting off the connection of an arc sputtering object between two static contacts. The contact system of the invention can effectively prevent the connection of the electric arc sputtering objectsbetween the two static contacts by arranging a protective structure between the two static contacts on the ceramic base, increase the creepage distance, restrict the dielectric withstand voltage levelof the electric life index of the contactor to be improved, and accordingly improve the electric life of the contactor.

The invention discloses a pressure different blockage charge valve with a plurality of air chambers, which comprises a valve shell, a valve needle and a forked needle. The valve needle capable of freely sliding is arranged in the valve shell, and the inner end of the valve needle is provided with the forked needle. The valve needle is provided with an inner annular protrusion and an outer annular protrusion, and a sealing ring is sleeved between the inner annular protrusion and the outer annular protrusion. The invention also provided with a valve nozzle matched with the pressure different blockage charge valve with the plurality of air chambers. The valve nozzle comprises the pressure different blockage charge valve with the plurality of air chambers, and at least two inner valves; each inner valve comprises an inner valve shell and a valve core, the number and distribution of the forked needle and the valve core correspond, the charge valve and the inner valve are connected through pressing seal or tightly connected through internal thread, and the charge valve is sleeved with a compression nut. The pressure different blockage charge valve with the plurality of air chambers and the matched combined valve can achieve charge and exhaust of a tyre with a plurality of air chambers, balance the air pressure of the air chambers when the pressure different of each air chamber is small, and block and separate the communication of the air chambers when the pressure different of each air chamber is large.

The invention discloses a dam by-pass seepage preventing water stop structure. By means of the dam by-pass seepage preventing water stop structure, the problem of by-pass seepage of a water stop part at a transverse joint part due to constructional deficiencies and the like is solved. The dam by-pass seepage preventing water stop structure comprises an along-joint water stop part in the position, inside a dam body section, of the transverse joint part, and the along-joint water stop part is provided with at least one separation water stop part. The along-joint water stop part is divided into a plurality of water stop section parts through the separation water stop parts, communicating of constructional deficiency parts which are randomly distributed is cut off, and by-pass seepage of the water stop part at the transverse joint part is avoided; accordingly, the water stop seepage preventing function of the dam is improved remarkably, and it is beneficial to find out the deficiency parts, so that the deficiency processing measure is targeted.
