Introduction to the design scheme of the emergency alarm system for subway train passengers [detailed explanation]

Emergency alarm device The emergency alarm device is set in the subway carriage, so that It can quickly call the police in case of an emergency. This thoughtful design ensures the safety of passengers and can be rescued in case of emergency. Charging equipment Charging equipment is set up in the subway car to facilitate passengers to charge.

Passengers should call 110 in time to call the police in the train. If the mobile phone is stolen, they can borrow the phone from others to call the police; if the situation is urgent, it may pose a threat to the safety of passengers and trains.

Electronic display: There are electronic display screens in subway stations and carriages to provide train arrival time, next stop and transfer information in time. Platform isolation door: In order to ensure the safety of passengers, isolation doors are usually set up on the platform of subway stations to prevent people from entering the rail area by mistake.

When the passenger faints, the train fails, the passenger's safety is threatened, etc., the passenger can launch an emergency alarm to the driver and contact the driver directly. There is a prominent sign on the outer cover of the passenger emergency alarm, and there is a red button inside. Passengers can open the cover in case of an emergency and press the red button to make a voice call directly with the driver.

Shanghai Metro Shanghai Metro has two sets of automatic fire prevention facilities: two-level automatic monitoring system, the first level is located at the station, and the first level is located in the central control room;Automatic fire extinguishing sprinkler system, with water spray and gas spray, can be regulated according to different fire causes. There are fire hydrants, emergency lighting and alarm phones in the tunnel.

Design of Fund Security System Architecture

1. Design of Fund Security System Architecture Design FundThe security framework, the formulation of fund security strategies and the establishment of fund security management mechanisms are only the first steps to implement the fund security system. Only when organizations at all levels can strictly implement the regulations on fund safety and conscientiously maintain the fund security of the sub-systems they are responsible for, can the overall safety of funds be ensured.

2. System architecture diagram: By using UML and other tools, draw the architecture diagram of the system, including the relationship between each module, data flow, system hierarchy, etc., to facilitate developers to understand and implement.

3. Data architecture; technical architecture; business architecture Business architecture is the basis of IT architecture. It should describe the implementation of the whole platform or a product from the perspective of business and product.

4. The capital structure of the project is designed to decide in the projectThe form of equity funds, quasi-share capital funds and debt funds, the proportional relationship between them and their sources of funds. The forms of debt often used for project financing include commercial loans, syndicated loans, bonds, commercial bills, government export credit, loan leasing, etc.

5. Opportunity identification and solution formulation, planning, implementation control, structure change management. The architecture can be divided into two levels: overall architecture and system architecture. Among them, the planning part mainly corresponds to the overall architecture, and the specific system corresponds to the system architecture.

monitoring system design scheme

manageability, adopting a centrally managed network architecture, real-time monitoring of monitoring operation status and monitoring content, and remote settings of the lower computer through the data center.THE OPERATING SYSTEM CAN BE UPGRADED REMOTELY THROUGH INTEL. Flexible installation and use to reduce the cost of network construction.

Directly hit the thunder. Directly hit the outdoor camera, directly damaging the equipment; directly hitting the cable, causing the cable to melt and damage. ( 2) Thunder and lightning intrusion wave.

An indispensable part of the design of the villa security system is the video surveillance and alarm system, which is installed in walls, gates, entrance doors and other places.

School leaders can monitor the monitoring screen at any point in real time through any terminal computer in the network, keep abreast of the on-site situation, and master first-hand information; with the help of school video surveillance, they can clean up the chaos of the surrounding environment of the campus and return peace to the campus.

What are the principles of enterprise information system security planning

1. Hierarchical principle The planning and design of enterprise security systems, from application system layer security, network layer security, to software and hardware system storage security, is designed according to the idea of layer-by-layer defense, and each layer should achieve the required security. Functions, jointly realize the overall security of the system.

2. Principle 1: "Barrel principle", that is, to protect information in a balanced and comprehensive manner. The volume of the barrel depends on the shortest wooden board", the attacker must attack in the weakest part of the system.

3. Design principles of information security system: barrel principle, overall principle, effectiveness and practicality principle, security evaluation principle, hierarchy principle, dynamic principle.

4. The principle of separation of checks and balances.In the information system, all permissions should be properly divided so that each authorized subject can only have a part of the permissions, so that they can constrain and supervise each other to jointly ensure the security of the information system.

5. The principle of minimum privilege The principle of minimum privilege refers to the allocation of rights to the subject in accordance with the principle of minimizing the rights required by the subject when the subject performs the operation. The principle of minimum leakage The principle of minimum leakage refers to the allocation of rights to the subject in accordance with the principle of minimizing the information that the subject needs to know when the subject performs the task.

6. The principle of clear purpose. The starting point of the security problem of personal information lies in the collection of personal information, that is, the situation that personal information is separated from the information owner and is controlled by others. In the process of collecting personal information, we must follow the principle of clear purpose. Choose the principle of consent.

When deploying a data center, which of the following security solutions need to be planned

When building a data center computer room, the following issues need to be paid attention to: site selection and load-bearing: after site selection, need to It is necessary to consider the load-bearing capacity of the building to avoid the need for reinforcement and renovation due to excessive weight. At the same time, the use of the space under the floor of the machine room should also be taken into account to avoid affecting the air delivery of the special air conditioner in the machine room.

Computer room security: According to the security needs of customers, design the physical security, network security, data security and other aspects of the computer room to ensure the safety and reliability of the computer room.

With the help of this solution combination, it not only has the advantages of high heat dissipation ability and reliability, but also makesThe server, storage and network equipment in the scheme allow safe and stable operation under higher temperature conditions to avoid the "strike" phenomenon due to high-temperature downtime.

Security of OA system?

1. System architecture security The system architecture of the application system has become an important defense line to protect the security of the system. In addition to ensuring the stability of the system, an excellent system architecture can also encapsulate business logic at different levels.

2. Then its security management requirements are correspondingly higher, especially in the case of remote office, the system needs to be deployed on the Internet. The security of the system, especially the security of the data, is very important. Therefore, when selecting OA products, usersFirst of all, we should pay more attention to OA software manufacturers with mature OA product technology and rich application cases.

3. What are the security risks of the OA office system? At present, the security risks of the OA office system can be roughly divided into the following categories: the security threats of force majeure external forces caused by natural disasters, accidents and other uncertain objective reasons, such as damage to the hardware of the OA office system, in the network The threat of disconnection and data loss, etc.

4. Different security requirements: the government OA system requires stricter information security measures, such as secret management, identity authentication, data backup, etc.; while the OA system of small and medium-sized enterprises has relatively low requirements for information security, but it also needs a certain security protection mechanism.

5. No matter what kind of network, absolutelySecurity is difficult to achieve, and with the continuous development of security needs and technologies, the security level of the system will continue to improve.

6. It is very common for the OA office automation system to have security risks due to the restrictions of various conditions such as technical conditions and personnel quality during the construction and maintenance process. At present, these security risks can be roughly classified into the following categories: the security threat of force majeure external disasters.
