1 General 1.3 Due to the rapid development of communication technology, electronic information technology and computer network technology, some new products (including hardware and software) and new technologies are often introduced. The security system equipment is different from ordinary household appliances and information equipment, so it must be safe and reliable. Therefore, the design of security system should not blindly pursue advanced and fashionable, but should adopt advanced and mature products or equipment that have been proved by practice and passed strict quality inspection or certification, and proved to be reliable in performance and relatively high in cost performance, so as to ensure the normal operation of security system all day long. 1.4 after China's entry into WTO, the state has implemented a compulsory certification system for products that meet the five legal objectives of WTO/TBT, and most security products are among them. Therefore, this specification stipulates that the equipment used in the security system must meet the requirements of the current relevant national standards and regulations. Products that are subject to compulsory certification must be certified by certification bodies, and products that are not subject to compulsory certification must also be inspected by relevant inspection bodies. 1.6 The responsibility to ensure the quality of safety prevention works is more important than Mount Tai. Safety engineering has different characteristics and requirements from general engineering. According to the practice of security engineering construction in China for more than 20 years, this specification considers that the following procedures are extremely beneficial to ensure the engineering quality. 1 engineering procedures the construction of safety and prevention works shall comply with the provisions of national laws and regulations and the relevant requirements of GA/T75 "procedures and requirements for safety and prevention works". See figure 1.5 for the basic procedure (emphasis is placed on the part marked with *). (Figure 1.6 Safety Precautionary Engineering Procedure Table, see page 25 of Standard Publicity and Training Textbook of Technical Specification for Safety Precautionary Engineering) 2 Requirements for main links of the project 1) Project establishment and feasibility study. A feasibility study shall be conducted before applying for the establishment of a safety prevention project. After the feasibility study report is approved, the project is formally established. The feasibility study report shall be compiled by the construction unit (or the entrusting unit). 2) Compilation of engineering design task book. The construction unit shall, according to the approved feasibility study report, prepare the project design task book, and conduct project bidding and contract signing in accordance with the Law on Project Bidding. The main contents of the design task book should include:-the source of the task; -Relevant regulations and management requirements of government departments; -Current national standards to be implemented; -Risk level and protection level of the protected object; -Contents and requirements of the project (including design, construction, commissioning, inspection, acceptance, training and maintenance services, etc.). ); -Construction period; -controlling the investment amount of the project; —— The expected effect to be achieved after the completion of the project; -Principles to be followed in engineering design; -System composition; -System functional requirements (including functional requirements of each subsystem); -Requirements of the monitoring center; -Security management system of the construction unit; -the response speed of receiving the police; Building plan. 3) Field investigation. See section 2 for specific requirements. 4) Scheme demonstration The engineering design unit conducts preliminary design according to the engineering design task book and the on-site investigation report. After the preliminary design is completed, the scheme demonstration must be organized. The scheme demonstration is presided over by the construction unit, with the participation of business departments, industry departments, design units and a certain number of technical experts, to review the contents of the preliminary design, evaluate its technology, quality, cost, construction period, service and expected effect, and put forward rectification measures. The design unit and the construction unit can carry out the formal design only after implementing the rectification measures. 5) Engineering inspection. See Chapter 7 of this specification for specific requirements. 6) Project acceptance. See Chapter 8 of this specification for specific requirements. 2 Field investigation 2. 1 The "field investigation" referred to in this specification is different from the "engineering geological and hydrological investigation" generally referred to in the field of engineering construction, and only refers to the understanding and investigation of the protected objects and all aspects related to the design of safety protection systems before the design of safety protection projects. Field investigation is the basis of design. Therefore, it is necessary to conduct "on-site investigation" before designing the safety system. For new projects or projects that cannot be inspected on site, it can be omitted. 2.2 The specific content of site investigation depends on the object to be guarded, generally including: geographical environment, human environment, physical defense facilities, civil air defense conditions, climate (temperature, humidity, rainfall, frost and fog, etc. ), lightning environment, electromagnetic environment, etc. The items listed in the terms of this specification do not require a comprehensive investigation of each item. 3 Design Elements 1 Security System The division of three construction modes aims to provide designers with reference for three different modes in system integration design. With the continuous development of information technology and network technology, the scale, integration depth and breadth of security system are also changing. "Integrated" mode will be the development direction of future security system. 3. Functions of main safety subsystems. As a subsystem of the security system, the parking garage (yard) management system mainly considers the security management requirements of intelligent buildings and intelligent communities. Because the safety of vehicles is also a social hot issue that the public is generally concerned about, it is beneficial to maintain the stability of social order to incorporate the safety of vehicles into the design of safety prevention systems. Other subsystems of security system refer to some security systems that are directly or indirectly used for security purposes in specific places or under special circumstances according to actual needs. For example, airports, stations, docks, large gatherings and activities need to be equipped with explosion-proof safety inspection systems, personnel identification systems, special goods identification systems, emergency evacuation broadcasting systems, etc. 5 safety design 5 safety of safety prevention system, including the safety of natural attributes and the safety of social and humanistic attributes. The safety of natural attributes generally refers to the technical requirements that the system (including the products it uses) can ensure the health and safety of operators and the safety of the equipment itself during operation, such as fire prevention, overheating prevention, electric shock prevention, harmful rays and toxic gases prevention, and mechanical injury prevention (such as explosion rupture, sharp edges, unstable center of gravity, and injuries caused by moving parts). The security of social and humanistic attributes usually refers to technical requirements such as preventing people from destroying equipment and systems, and preventing people from stealing and tampering with information. 6 electromagnetic compatibility design 6 electromagnetic compatibility (EMC) design of security system includes electromagnetic interference and anti-electromagnetic interference, involving equipment selection or design, transmission medium selection and transmission route design. , more content, more difficult. In view of the fact that the industry standard "Technical Requirements for Electromagnetic Compatibility of Security Systems" is being formulated, this specification only puts forward the principle requirements for the electromagnetic compatibility design of security systems, aiming at reminding system designers to pay attention to the electromagnetic compatibility design, especially the electromagnetic compatibility requirements for equipment. The equipment used in the security system basically belongs to electronic information equipment. The electromagnetic compatibility test of equipment used to be based on GB6833 series standards, but now it is based on GB/T 17626 series standards. These standards are: electromagnetic compatibility test and measurement technology electrostatic discharge immunity test GB/T 17626.2, electromagnetic compatibility test and measurement technology radio frequency electromagnetic field radiation immunity test GB/T 17626.3, electromagnetic compatibility test and measurement technology electric fast transient immunity test GB/T 17626.4, electromagnetic compatibility test and The strict level of immunity test GB/T 17626.5 and electromagnetic compatibility test and measurement technology voltage drop test shall be determined by the builder and designer through consultation according to the electromagnetic compatibility environment and actual needs of the system or equipment. 7 Reliability Design 7 Theoretically, the so-called reliability refers to the ability of the product (system) to complete the specified functions within the specified time under the specified conditions (service conditions = working conditions+environmental conditions). There are many mathematical features to quantitatively express reliability. This specification adopts the most commonly used feature-MTBF (Mean Time Between Failure) as the technical index to measure the reliability of the system (product). When designing system functions, we should consider the compatibility of system functions, performance indicators and reliability indicators at the same time, and avoid the tendency of blindly pursuing too many functions and too high indicators at the expense of system reliability. The reliability of the system is a very complicated problem, and it is difficult to quantitatively test it in a short time with simple methods. This specification focuses on the reliability of equipment and the maintainability and maintainability of the system. 9 lightning protection and grounding design 9 lightning protection design of safety protection system is also an important content of system safety design. For a fixed target, the security system is often based on buildings or structures, so the lightning protection of buildings (structures) is the basis and premise of the lightning protection of security systems. However, because the security system is essentially an electronic information system, the security system focuses on the lightning protection of the information system in addition to the lightning protection of buildings. Theoretically speaking, the lightning protection of buildings and information systems has different properties and contents. For the lightning protection of information systems, the International Organization for Standardization (such as IEC) and China's Technical Committee for Lightning Protection Standardization are organizing experts to formulate relevant standards. The lightning protection design requirements proposed in this specification are mainly based on the relevant provisions of the current national standards "Code for Lightning Protection Design of Buildings" GB50057 and "Technical Code for Lightning Protection of Building Electronic Information Systems" GB50343, and combined with the actual situation of lightning damage to the safety protection system in China, the design focus should be on the lightning protection and grounding design of the monitoring center. 13 design of monitoring center 13 the monitoring center of safety protection system is the nerve center and command center of the system. In addition to the safety protection requirements of the control room itself, this specification also puts forward requirements for the environmental problems of the control room, aiming to remind designers to implement the principle of "people-oriented" and create a safe, comfortable and convenient working environment for the personnel on duty according to the principles of ergonomics and relevant requirements of environmental protection. 1 General 1.3 Due to the rapid development of communication technology, electronic information technology and computer network technology, some new products (including hardware and software) and new technologies are often introduced. The security system equipment is different from ordinary household appliances and information equipment, so it must be safe and reliable. Therefore, the design of security system should not blindly pursue advanced and fashionable, but should adopt advanced and mature products or equipment that have been proved by practice and passed strict quality inspection or certification, and proved to be reliable in performance and relatively high in cost performance, so as to ensure the normal operation of security system all day long. 1.4 after China's entry into WTO, the state has implemented a compulsory certification system for products that meet the five legal objectives of WTO/TBT, and most security products are among them. Therefore, this specification stipulates that the equipment used in the security system must meet the requirements of the current relevant national standards and regulations. Products that are subject to compulsory certification must be certified by certification bodies, and products that are not subject to compulsory certification must also be inspected by relevant inspection bodies. 1.6 The responsibility to ensure the quality of safety prevention works is more important than Mount Tai.
