Disclosed is a door control monitoring system, comprising a plurality of optical fibre sensors and an optical link detection system. The optical fibre sensors are respectively arranged at a position of the body of a case close to an edge of the door of the case. An optical fibre sensor comprises an optical fibre, a reflection module and a transmission structure. The reflection module is connected in series in the optical link detection system via the optical fibre. The transmission structure is elastically connected to the reflection module. The door of the case is closed such that the transmission structure is shifted by a force and pushes up the reflection module, so as to change the reflectivity of the reflection module. The door of the case is opened such that the transmission structure is returned back, and the reflectivity of the reflection module is restored. The optical link detection system senses the reflectivity of the reflection module, so as to monitor the opening and closing of the door of the case. The door control monitoring system of the present invention can effectively monitor various states of the door of a case, and cannot influence the service quality of a link.

The invention discloses lighting skylights and a transformation method thereof, and relates to the field of roof transformation of buildings. According to the key points of the technical scheme, the transformation method comprises the following steps that S1, a rigid protective layer is made on an original lighting ceiling; S2, a plurality of sets of steel structures are welded to original I-shaped steel of the original lighting ceiling; S3, the openable lighting skylight is mounted on each set of steel structure; S4, gluing is conducted for close-up; and S5, glass plates and the rigid protective layer in the original lighting ceiling are dismantled. The lighting skylights and the transformation method thereof have the technical effects that 1, the shape of the original lighting ceiling isanalyzed, the openable lighting skylights are additionally arranged on the original lighting ceiling, the glass plates of the original lighting ceiling are removed, thus the new lighting ceiling structure is formed, and firefighting smoke-discharging and natural ventilation can be achieved on the new lighting ceiling; and 2, an area below the original lighting ceiling is not affected by the transformation method, for example, when a shopping mall is transformed, normal operating is not affected.

The invention discloses a mobile communication inter-network signaling protection method and device, which overcomes the defects still existing in the mobile communication safety protection method and equipment in the prior art. The invention contains an external network and an internal network, the external network is a mobile network, and the internal network is a target mobile network entity; the interface between the external network signaling transfer point STP and the interface of the internal network signaling transfer point STP has no sense of access There is a bottom-level processing device, and the standard No. 7 signaling protocol is adopted between the bottom-level access device and the internal and external network signaling transfer point; the bottom-level access device receives the signaling and forwards it to the device, which is connected to the protective device through a custom interface , The transport layer of this interface adopts UDP protocol, and the application layer adopts a custom protocol. The invention detects and processes the signaling message initiated by the external mobile operator network under the condition of ensuring that the normal business of the operator is not affected, and prevents malicious interference behavior of the external network.

The invention discloses an IDS (Intrusion Detection System) feedback-based SDN (Software Definition Network) flow sampling method and system. A flow is temporally sampled at first through the centralized control capacity of an SDN controller for a network flow, and then is sent to an IDS for primary detection, and whether to continue to sample the flow or not is determined according to a detectionresult of the IDS, thereby improving the sampling accuracy; and under a condition of a limited bandwidth, a flow with a high threat degree is selected for detection as much as possible to improve theutilization rate of the sampling bandwidth and the detection precision. The IDS feedback-based SDN flow sampling method is easy to implement and high in feedback speed; an independent sampling tableis used for implementing sampling, so that the sampling cannot affect normal services; and the method has the deploying capacity in an actual system, in particular in a cloud data center.

The invention discloses a RAM failure detection and processing method, which is applied to the detection and processing of CPU / DSP RAM failure, including: reading the program content in the RAM; if the RAM can be controlled by the high-level of the CPU / DSP Entity access, then compare the program content read with the correct program content by the high-level control entity, when the two are inconsistent, judge that the RAM is invalid and perform data repair; if the RAM cannot be accessed by the high-level CPU / DSP Control entity access, then the program content read by the CPU / DSP is verified by a set verification method, and compared with the correct verification result, when the two are inconsistent, it is judged that the RAM is invalid and Call the police. By adopting the method of the invention, the failure of the CPU / DSP RAM can be detected in time, and corresponding processing measures can be taken in time to minimize the influence caused by the failure of the RAM.

The invention discloses a method for protecting an L2TP network. The method includes: standby L2TP? The LNS backs up the information of the current online L2TP user on the active LNS, the information of the L2TP tunnel corresponding to the L2TP user, and the information of the L2TP session; when the active LNS itself or the link where the active LNS is located fails, the backup The LNS and the active LNS perform active / standby switchover; the standby LNS refreshes routes and forwards user traffic according to the information of the backed up L2TP tunnel and L2TP session. The invention also discloses a protection system of the L2TP network, which ensures that the failure of the LNS device and its link does not affect the normal business of the L2TP user, and that the L2TP user and the LAC cannot perceive the occurrence and recovery of the failure, and realizes the protection of the L2TP network. Troubleshooting can effectively improve the user experience of the L2TP network.

The invention relates to a physical exchange system based on an E1 / T1 circuit, which comprises a main exchange system and a plurality of independent slave exchange systems, wherein each slave exchange system is freely connected with the main exchange system which is connected with a workstation terminal, each salve exchange system is provided with at most 64 paths of E1 / T1 signal interfaces, receives signals from the E1 / T1 signal interfaces and transmits the signals to the main exchange system; meanwhile, the slave exchange systems receive output signals of the main exchange system, divide the signals into at most 64 paths of E1 / T1 signals according to the information of channel numbers in the signals and send the E1 / T1 signal out. The invention can achieve the effects of simplifying the exchange control logic and design complexity configured by a user, shortening the data exchange delay, configuring a replacement 0-delay switching, not influencing the normal service and not losing data; the quantity adjustability of system interfaces is greatly increased, the usability is greatly improved, and the requirement for frequency jitter toleration of input data is wider.

The invention provides a base station fault detection method. In the method, by periodically executing online detection on an uplink pilot time slot (UpPTS) signal loop, namely, detecting whether the processes that the uplink synchronous signals on the UpPTS routes from a RRU to an uplink synchronous detection module for detection via data routing and the uplink synchronous detection module submits the detection result to a layer 1 baseband processing module, are regular, the currently happed random access fault can be known in time under a condition of having no influence on the regular services and having very small influence on the system load.
