It includes the natural environments in which humans rely on to live, such as the atmosphere, water space, soil space, rocky space, and biosphere; but also social environments in which humans live.
Environmental factors affecting human health can be divided into three major categories: physical factors (e.g., noise, vibration, radioactive substances, radio frequency radiation, etc.); chemical factors (e.g., toxic chemicals, heavy metals, pesticides, etc.) and biological factors (e.g., bacteria, viruses, parasites, etc.). They can be harmful to human health through various routes, into the air, bodies of water, soil and residential environments, with chemical factors being the most important.

In addition, General Packet Radio Service (generic Packet Radio Service) is a mobile data Service available to GSM mobile phone users. GPRS is said to be a continuation of GSM. GPRS is different from the conventional method of continuous channel transmission in that it is transmitted in Packet (Packet) mode, so the cost of the user is calculated in units of the data to be transmitted, rather than using the entire channel, and is theoretically cheaper. The transmission rate of GPRS can be increased to 56 or even 114 Kbps.
GPRS is often described as "2.5G", meaning that the technology is located between second generation (2G) and third generation (3G) mobile communication technologies. He provides moderate data transfer by utilizing unused TDMA channels in the GSM network. GPRS breaks through the thinking that GSM networks can only provide circuit switching, and packet switching is implemented only by adding corresponding functional entities and partially modifying the existing base station system, which is relatively inexpensive in investment, but the obtained user data rate is considerable. Furthermore, connection and transmission are facilitated since the intermediate switches required by current wireless applications are no longer required. Therefore, the user can not only online and participate in interactive transmission of video conferences, but also the user on the same video network (VRN) can continuously connect with the network without dialing the network.
GPRS packet-switched communication in the packet-switched communication mode, data is divided into packets of a certain length, each packet being preceded by a packet header (where the address tag indicates where the packet is destined). The channel is not required to be allocated in advance before the data is transmitted, and the connection is established. Instead, upon the arrival of each packet, an available channel resource is temporarily sought to transmit the datagram based on information in the data header (e.g., destination address). In this transmission method, there is no fixed occupation relationship between the sending and receiving sides of data and the channel, and the channel resources can be regarded as being shared by all users. Since data services exhibit a bursty service characteristic in most cases and the demand for channel bandwidth varies greatly, packet-based data transmission can make better use of channel resources. For example, a user browsing the WWW is most of the time in the browsing state, while the time actually used for data transfer is only a small percentage. In this case, if the channel is fixedly occupied, a large amount of resources will be wasted.
By adopting the intelligent control box at the traffic intersection, aiming at the technical problem that the labor amount of urban sanitation dispatch is difficult to control in the prior art, the structure of the existing control box at each traffic intersection is modified, on one hand, high-precision and targeted image recognition equipment is integrated to collect real-time pedestrian flow data at the traffic intersection, and on the other hand, effective control box communication equipment is integrated to realize labor dispatch control of sanitation service sites near the traffic intersection address based on the real-time pedestrian flow data.
