Use Siemens GSM module, use 32-bit processor, support Chinese SMS command for remote control, send SMS with mobile phone, remote switch, timing, data acquisition, control relay. After the operation is successful, the control box will return a confirmation message. Send a query command and the control box will return to the current working state of the relay.
The GSM SMS controller developed by Shengxiang Technology is a network service based on SMS service, which can support users to edit SMS messages through mobile phones. Send SMS messages to remotely control electrical equipment to work, thus enabling automated control of unattended locations. As a wireless remote control device, the GSM short message controller uses the SMS service to enable other local restrictions. That is to say, as long as there is a cell phone signal, the SMS controller can communicate and work. As a wireless and automated device, SMS controller is being used by more and more users as a mature technology in many industries.
Application areas:
1. Control all kinds of valves: connect the two terminals of the controller with various types of sensors. The sensor transmits external physical quantities such as temperature and humidity, water level, acid and alkali, etc. to the SMS remote controller, and the controller will control the electromagnetic according to the returned value. The valve is turned on and off to complete the industrial progress.
2, control motor, server remote boot: can be used as a continuous operation of network equipment (such as: industrial computer, room server, etc.) remote boot, reset control.
3. Control unattended base stations: Some base stations and computer rooms are located in harsh environments, which is not conducive to manual guards. Installing SMS remote controllers in these places can save manpower and material resources, and complete monitoring and alarming of remote wireless control room, base station servers, air conditioners, fans and other equipment.
4. Control multiple water pumps: For the inconvenient water pump in the hilly area of the mountain, connect the SMS remote controller to the AC contactor of the pump, and the management personnel can use the mobile phone to send SMS messages to the mobile phone card during the control period.
To control the start and stop of the pump. You can also send a text message at any time to understand the working status of the pump. It can control a maximum current of 30A and a remote controller can control up to 6 pumps.
5. Control the opening and closing of doors and windows: It can be combined with the electromagnet type door bolts. It can use GSM to remotely control the door and window switches, or it can be manually opened with a key to lead the development of intelligent doors. It is connected with the electric control lock of the control window, which can remotely control the opening and closing of the door and window, which is convenient when it is raining or when there is an emergency.
