GSM Remote Control Power System Customer Demand Analysis I. Overall design of the project The system design module is a control system composed of a GSM module plus a single-chip microcomputer. The whole system consists of a controlled end, a remote control host, and a code-specific distribution host; it can remotely control the controlled point through a remote control host; The host is used to configure the remote host, allowing the host to add a new controlled number to the remote host module. After receiving the command, the remote host assigns a number and returns it to the encoding host; the remote host performs the controlled module according to the number. Control; The controlled end is responsible for accepting only the control command sent by the remote control host and turning it on or off according to the command. System composition II. Component introduction of remote control system A, the function and brief introduction of the host remote control module 1, responsible for the opening and closing of each controlled module, 2, supports up to 999 controlled points, 3, with power off storage data function, save time not less than 50 years; 4, at the same time provide TTL level serial port, support computer communications, in case of future use of computer backup data; as shown below: Examples of operating methods: The first step, standby, enter the number of the controlled end, such as '023', this time digital display 023; The second step, press the 'open button', the host immediately open the port after receiving the instruction! The instruction to start the host B. Code allocation dedicated host module Description: The following referred to as encoding host The coding host is the code distribution dedicated host module, used to add the controlled number to the remote control host. If the controlled module is not fixed on the remote control host through the distribution, it is unable to achieve the purpose of remote control. Only the coded host can control the controlled module. After the number is programmed into the remote host, the remote host can really achieve the control effect, as shown in the following figure: Examples of operating methods: The first step, standby, send a short message such as '#023@13860xxxxxx' to the host remote control After the second step, after the completion, the system will return 'OK' to the specified host, indicating successful registration! After the success can be controlled by the remote control host (detailed operating examples of remote control host) C, the function of the controlled module Responsible for receiving commands sent by the remote control module of the host and executing corresponding operations according to the instructions. After the execution is completed, the host is allowed to send information to inquire information and provide related query results. When the controlled end loses power unexpectedly, it can store the current state in time so that the next time it starts up, it will continue its original state! Third, security considerations At present, the services provided by GSM can make people free from space and geographical restrictions, and obtain the required information anytime and anywhere. GSM (Global System for Mobile Communication) means global mobile communication system, hereinafter referred to as GMS short message remote control module. Its data service communication is a communication method developed on the basis of data communication. The previous data communication relied on wired transmission, so it was only suitable for communication between fixed terminals or computers. Nowadays, wireless mobile data communication transmits data through radio waves, and thus it is possible to realize more distant data communication. As a data communication network medium, GSM can realize bidirectional real-time communication of data across provinces and cities nationwide. It can extend the use of wired data networks to wireless mobile and portable users. In addition, GSM communication also features high confidentiality, excellent reliability, and strong anti-jamming capability, ensures the accuracy and stability of data transmission, and provides a complete communication protocol between the two parties, making it easy for users to develop on this communication platform. The GSM system has the advantage that conventional wireless communication or wired communication carriers are difficult to match. Therefore, the GSM-based remote monitoring and control system is gradually being widely used. In some special industries such as railways, petroleum, and mining, traditional monitoring often has many problems: high cost, efficiency, poor safety performance, and inconvenient maintenance. The GSM-based remote monitoring system can overcome these deficiencies well. It is very convenient to establish a fast and effective monitoring system through the existing mobile communication network. The GMS short message remote control module is the most mature, most user, and most widely used system in the current mobile communication system based on time division multiple access technology. China has built a nationwide GSM digital cellular mobile communications network. With the multiple services it can provide, in addition to basic traffic services, it also provides value-added services such as fax, short message, and data transmission, and can carry out remote monitoring work based on GSM. First, various metering and monitoring stations are arranged at the industrial site to perform primary data collection. The field bus collects all kinds of information collected from the site and collects it on the site's monitoring workstation. The workstation acts as a down-level machine. The remote monitoring terminal (computer, mobile phone) can be used as a host computer to make an active call through an instruction, or the lower computer can actively send field data to a remote host computer. Therefore, engineering and technical personnel can save a lot of manpower and material resources, orderly complete various maintenance monitoring tasks, and ensure that the entire enterprise unit can operate safely and efficiently. For example, in the railway system, the workload of hydropower projects is particularly large. The power supply system provides continuous supply of voltage and energy for the production and livelihood of the railway system. The water supply system provides domestic water, which meets relevant standards for water quality and water pressure, for the railway production and daily life. As a result, railway water supply and power supply systems are the basic departments that guarantee the normal production of railways, and their production and management levels are directly related to the safe and orderly production of railways. Utilize technologies such as modern computers, electronic measurement and communication networks to carry out technological transformations for hydropower stations, implement remote online monitoring and management based on GSM for substations, etc., automatically record working conditions and manage data, and achieve single or even unmanned management. Production purpose. The GSM-based remote monitoring is gradually expanding and has broad application prospects based on its cutting-edge technologies and obvious advantages.
