Is there a distance limit for mobile phone remote control?

Remote control refers to automatically sending peripheral control instructions through networked PC or mobile phone, which is called remote automatic control. Remote automatic control mainly provides monitoring means for managers in different places, and sends control instructions after manual judgment and data analysis to enhance managers' initiative and intervention ability.

The management center of automatic control system consists of programmable controller (PLC), central management computer, GSM wireless communication module and data management software. The function of the control system is to control the GSM wireless communication module to send alarm information and operation data to the designated mobile phone, and calculate, process and execute the control commands sent by the remote computer or mobile phone terminal.

The remote control terminal consists of a computer and a GSM wireless communication module. The function of the remote control terminal is to process and display the received data information by controlling the GSM module to send and receive short messages and control commands. The user's mobile phone terminal can receive the alarm information sent by the automatic control system, and know the operation details of the system through short message commands.

The remote control system is mainly composed of a remote control transmitter, a remote control receiver and a microprocessor. Microprocessor is the main part of the remote control system, which is used to process and control the signals that the transmitter needs to transmit. Microprocessor and integrated circuit constitute remote control transmitter, which is what we usually call remote control (mobile phone in this paper), and remote control receiver is installed in various electrical equipment.

Feasibility of mobile phone remote control

Using a mobile phone as a remote controller must consist of the above three parts. As a remote control transmitter and microprocessor, the corresponding remote control equipment must have a remote control receiver to realize remote control. Remote control can only be realized by remote control receiver. Generally, a remote control terminal, such as a television, will have a receiver and a signal decoder to analyze and manipulate signals sent by the remote control.

If you need a mobile phone to control WIFI and Bluetooth devices, the WIFI and Bluetooth devices should be equipped with customized signal receivers and decoders for control operation, so that the mobile phone can remotely control WIFI devices, such as WIFI remote control aircraft.

Therefore, from the analysis of the composition of the remote control system, it is feasible to remotely control computers or other intelligent devices with mobile phones. Only by customizing the software of the control terminal and the software of the controlled terminal can remote control be realized.
