摘要：【中文】本发明实施例公开了一种安全接入网关的准入控制方法、装置、设备和介质。该方法包括：接收用户终端发送的身份认证请求，并根据身份认证请求中携带的身份验证信息验证用户的身份；若对用户终端的身份验证通过，则根据身份认证请求中携带的属性信息查询用户终端的安全风险等级；根据用户终端的安全风险等级确定与用户终端对应的准入策略；根据准入策略控制用户终端连接目标服务器。本发明实施例能够对接入服务器的用户终端进行安全风险等级的分类，指定对应的准入策略，有效保证连接目标服务器时的安全性。 【EN】The embodiment of the invention discloses an admission control method, a device, equipment and a medium for a security access gateway. The method comprises the following steps: receiving an identity authentication request sent by a user terminal, and verifying the identity of a user according to identity verification information carried in the identity authentication request; if the identity of the user terminal passes the authentication, inquiring the security risk level of the user terminal according to the attribute information carried in the identity authentication request; determining an admission strategy corresponding to the user terminal according to the security risk level of the user terminal; and controlling the user terminal to connect with the target server according to the access strategy. The embodiment of the invention can classify the security risk level of the user terminal accessed to the server, appoint the corresponding access strategy and effectively ensure the security when connecting with the target server.

摘要：【中文】本发明属于直升机液压系统设计技术领域，公开了一种用于直升机液压系统的污染度监控方法，所述方法包括：S1，获取油滤的压差‑剩余纳污容量常规曲线；S2，直升机在使用过程中，监控直升机液压系统油滤前后端的实时压差；S3，根据所述实时压差，并对照压差‑剩余纳污容量常规曲线，获得直升机液压系统油滤的剩余纳污容量，能够准确评估液压系统污染状态，有效监控液压系统健康状态，减少维护工作量。 【EN】The invention belongs to the technical field of helicopter hydraulic system design, and discloses a pollution degree monitoring method for a helicopter hydraulic system, which comprises the following steps: s1, acquiring a conventional curve of differential pressure-residual pollutant carrying capacity of the oil filter; s2, monitoring the real-time pressure difference of the front end and the rear end of an oil filter of a helicopter hydraulic system in the use process of the helicopter; and S3, obtaining the residual pollutant carrying capacity of the oil filter of the helicopter hydraulic system according to the real-time pressure difference and by contrasting a pressure difference-residual pollutant carrying capacity conventional curve, accurately evaluating the pollution state of the hydraulic system, effectively monitoring the health state of the hydraulic system and reducing the maintenance workload.

摘要：【中文】本发明提供了一种空调化霜控制方法、系统及空调，检测空调当前运行模式，若空调运行模式为制热模式，检测外管温度，若外管温度满足判断条件，则开启电器盒底部的热气旁通管；若空调系统满足进入化霜条件，持续开启热气旁通管，化霜完毕后关闭热气旁通管。本发明通过在电器盒增加的热气旁通管，机组制热运行过程中，通过热气旁通管控制室外机的六路，可以使电器盒内元件工作的热量排放流经室外机，提高室外机换热效果，无霜是减少化霜效率，当化霜时排放高温热量，实现快速化霜或除霜干净，缩短化霜时间，可持续向房间供热，进一步减少房间温降量，提高房间人体舒适性。 【EN】The invention provides an air conditioner defrosting control method, an air conditioner defrosting control system and an air conditioner, wherein the current operation mode of the air conditioner is detected, if the operation mode of the air conditioner is a heating mode, the temperature of an outer pipe is detected, and if the temperature of the outer pipe meets a judgment condition, a hot gas bypass pipe at the bottom of an electric appliance box is opened; if the air conditioning system meets the condition of entering defrosting, the hot air bypass pipe is continuously opened, and the hot air bypass pipe is closed after defrosting is finished. According to the invention, the hot gas bypass pipe is additionally arranged on the electric appliance box, six paths of the outdoor unit are controlled by the hot gas bypass pipe in the heating operation process of the unit, so that heat generated by elements in the electric appliance box during working can be discharged and flows through the outdoor unit, the heat exchange effect of the outdoor unit is improved, the defrosting efficiency is reduced due to no frost, high-temperature heat is discharged during defrosting, quick defrosting or defrosting cleanness is realized, the defrosting time is shortened, heat can be continuously supplied to a room, the temperature drop of the room is further reduced, and the human body comfort of the room is improved.
