HJ 661-2013Coding rules for monitoring point of environmental noise (English PDF)

3.1 Urban Environmental Noise routine monitoring

According to HJ 640, also known as the routine monitoring it means for mastering environmental quality in the city, carried out by the environmental protection department Regional acoustic environment monitoring, traffic monitoring and sound environment Sound Environment Monitoring (abbreviated. regional monitoring, road Traffic monitoring and monitoring of functional areas).

3.2 Ribbon

According to GB 3096 and GB/T 15190 of the divided city of various types of environmental noise applicable zone.

3.3 Environmental noise monitoring sites

To carry out routine monitoring of urban sound environment, according HJ 640 ( "environmental noise monitoring technical specifications conventional urban acoustic environment Monitoring ") all kinds of noise monitoring points set.

4.1 Uniqueness

Each environmental noise monitoring sites only use a code, a code only represents an environmental noise monitoring sites.

4.2 Rationality

Noise monitoring sites coding structure of the most stable environment to its attributes or characteristics as the basis and foundation to ensure that the coding Scientific and systematic.

4.3 Scalability

Taking into account the ambient noise monitoring sites continues to develop and change, environmental noise monitoring sites coded to leave after appropriate Equipment capacity to meet expanding needs.

4.4 Applicability

With the development of environmental noise monitoring, environmental noise monitoring sites constantly change and update, therefore, to encoding Targeted to be classified, focused and easy to use.

4.5 Normative

Environmental noise monitoring point coding system, the coding type, structure and preparation of a unified format.

5.1 Basic Methods

This standard follows the basic encoding method GB/T 7027 regulations and requirements of.

5.2 Coding Composition

Environmental noise monitoring sites encoded consists of three parts, as shown in Figure 1, respectively administrative division code, category-generation monitoring sites Code and monitoring sites sequential code. The first part of the coded representation of the monitoring point location administrative division code, detailed to a county Level, with six Arabic numerals, determined according to GB/T 2260; the second part of the encoded representation monitoring sites category code, with two Arabic numerals, ie 01-99, by the standard (see Table 1); the third part of the encoded representation monitoring sites along Program code, with four Arabic numerals, ie 0001-9999, and the monitoring sites sequential code in the first and second portions Sub-coding phase while not reused by the local environmental protection regulations of the administrative department.

5.3 Classification and composition of the monitoring sites category code

Environmental noise monitoring sites by region encoding the second part of the acoustic environment monitoring, traffic monitoring and acoustic environment on the Sound Central Environmental monitoring and other categories of classification. Table 1 lists the code and the name of the category of environmental noise monitoring sites encoding the second portion.
