The use of wired control and wireless control in combination

Image
People make use of radio frequency wireless control technology, first, make a simple connection between the controlled equipment and the wireless receiver, and then use the transmitter to remote control the receiver, in order to achieve wireless control of the devices. The wireless control system has the following advantages: 1.     The installation is simple, no need to install a large number of wires, the overall cost is greatly reduced.  2.     The operation is convenient. The user can carry on the wireless control of the equipment in any reliable range with the remote control. 3.     To achieve remote control, wireless control can be implemented in a quite far range, such as 1000M or farther. The wireless remote control technology brings convenience to mankind, but it also causes inconvenient. 1.   When the user cannot find the remote control or the remote control is lost, the device cannot be controlled. 2.   When the remote is lost, it takes the user to spend t

Wireless remote control crane

Wireless remote control technology has been very widely used. Whether it is satellites or household appliances mostly can be controlled by wireless remote control technology. RF control can fully liberate people from complicated manual labor, and wireless operates any electronic equipment at a distance as much as they want. The development of wireless remote control technology make people enable to enjoy the charm of science, also reduce labor intensity, improve labor productivity, and improve job safety. Crane is mainly used to load and unload objects, widely used in construction sites, commercial, factories, farms, supermarkets, and other occasions. Using wireless remote control technology can achieve crane wireless control. Crane wireless remote control system has the following advantages. 1. Reducing manpower costs. For cranes, truck cranes and other equipment, the operator can operate the equipment along with the wireless remote control technology, and no longer need the assis

Code setting and modification of C series transmitter

Image
The C Series is the most commonly used transmitter with many advantages.It is compact which means easy to carry, and with a sliding cover to prevent misuse of the button. We provide single-button transmitter, 2 button transmitter, 3 button transmitter and 4 button transmitter, as shown in figure: C series transmitter has a fixed code and learning code two types. The fixed code transmitter needs to be set by Soldering iron. Learning code transmitter can be used directly.Fixed code transmitter usually use PT2262 or SC2262 encoding chip, we generally use 8-bit address code and 4-digit date code. The total capacity of address code has 6561 group. The address code is set by pins 1 ~ 8 of PT2262 or SC2262. These 8 pins can be set to three states: floating, grounding and connecting to the positive power supply. These three states represent codes 0, 1 and 2, respectively. So the address code consists of 0, 1 and 2, such as 00210210 or

The coding mode of radio remote control: fixed code and learning code

The wireless remote control system is a device used to control the machine remotely, it was first developed by Nicola Tesla in the United States in 1898. There are two common remote control systems on the market, one is IR Remote Control, which is commonly used in various household appliances, such as TV and air conditioning; the other is the RF Remote Control, which is commonly used in anti-theft alarm equipment, door and window remote control, car remote control and so on. The radio remote control system (RF Remote Control) is a remote control device that uses radio signals to control a variety of equipment in the far distance. These radio signals can be received by remote receiving devices, which can drive all kinds of other mechanical or electronic devices to complete various operations, such as a closed circuit, mobile device and actuate motor. Radio remote control has been widely applied in the garage door, electric door, road gate remote control, burglar alarm, industrial

Four-button wireless remote control transmitter (IC PT2262 / SC2262)

There are two types of wireless remote transmitters: electromagnetic waves and infrared. The working distance of the infrared remote transmitter is short, and the infrared ray can only be transmitted through the straight line, and can’t bypass the barrier. RF remote transmitter uses the RF signal, it is transmitted in all directions, and the signal can cross a certain barrier. The electromagnetic wave wireless remote control system uses the transmitter to transmit the electromagnetic wave, and the receiver extracts the electromagnetic wave and triggers various devices. The electromagnetic wave wireless remote control system commonly used in burglar alarm equipment, industrial equipment, doors and windows remote control, car remote control. The following describes a commonly used four-button wireless remote control transmitter, the parameters are as follows: Working voltage: DC12V (23A / 12V battery) Working current: 10mA / 12V Modulation method: ASK Frequency: 315MHz / 433M

Automatic Water Level Wireless Remote Control System

Image
In industry, agriculture and daily life, water for the processing of beverages and foodstuffs, water for chemical production and domestic water supply, etc. People usually use pumps and tanks to form a pumping system. Earlier, people used manual control systems to control the water level in pumps and tanks. Later people used water level sensors and wired controls to automatically control the water level in pumps and tanks. For example, when the water level in the tank is too low, the pump is automatically activated to pump water to raise the water level; or, when starting the motor pumping water, the water pump is automatically shut down once the water level in the tank reaches the proper level. Now we can use more innovative wireless control technology to achieve wireless automatic control of water levels in pumps and tanks. The wireless control system is usually suitable for pump far away from the water tank occasions. One of our clients told us his trouble. He wanted to control a

Wireless remote control electric rolling gate

Image
In daily life, the electric rolling gate is suitable for family, shop, garage, market, hospital, warehouse and company. The control of electric rolling gate is divided into wired control and wireless control. Wired control systems include rolling door, motor, and manual switch. The user needs to go to the edge of the rolling gate before using the manual switch to open/close the rolling door. If you want to open the door when you are in the car, you have to get off and press the manual switch.   In winter it is very inconvenient. The wireless control system includes rolling door, motor, remote controls and a wireless receiver connected to the motor.   The user can use the remote control to turn on/off the rolling door at a reasonable distance.   When the user presses the remote control button, the remote will send an RF wireless signal.   This RF wireless signal can pass through trees, walls or doors and windows. After the wireless receiver receives this RF wireless signal tha
