alarm system, wireless control

Each alarm system has a central unit and several detectors. But to make the use and management of the alarm more convenient, you should use the keypad and the alarm remote control.

The Alarm remote control

The remote alarm is a very practical accessory to have under control the whole security system of a house, even at a certain distance. For example, a remote control can be used to activate the alarm when the owner of a house leaves the house to go somewhere. It is then no longer necessary to go back down from the vehicle to activate the alarm, which can be managed from the car by simply pressing a button. When the house in question is equipped with a home automation system, the rf remote control becomes even more practical. Not only does it activate or deactivate the alarm remotely, but it also gives the possibility to perform other remote actions, such as opening or closing the garage door, closing the blinds, activating or deactivating the automatic watering can for lawns, and many other devices. The alarm remote control usually has a button that sends a panic alert to the numbers pre-registered in the alarm central. This button can be very useful when an abnormal event occurs: during a malaise, a fire or an intrusion with aggression, etc.

 The alarm keypad handle all the activation of the alarm

The keypad has practically all the functions of the remote control, except that it allows all the alarm settings to be made. Indeed, the keypad allows not only to activate or deactivate the alarm, but also to determine for example the emergency numbers to be alerted by the GSM or long range. It is also thanks to the keyboard that it is possible to manage the difference in sensitivity of the alarm for the different rooms. Generally, the keypad is incorporated into the alarm unit. It is therefore important to install it in a location where the relationship with the various detectors and other safety devices can be interference-free, especially if it is a wireless alarm. It should also be noted that an alarm keypad should not be installed near the front door when it is incorporated into the alarm unit, as it would be easy for burglars to destroy it in a very short time and force the alarm to deactivate itself.

Optimize keyboard use

In most cases, the alarm keypad is used to replace the digicode and to arm or disarm the home alarm. But you should know that some alarm keyboards have special functions. It can happen that burglars can enter a business premises or even a home, and threaten the owners with a weapon to deactivate the alarm as quickly as possible. There are then some keyboards that are programmed with two codes: the first is the real code that enables or disables the alarm. The second, on the other hand, is an a businessemergency code: when it is typed on the keypad, the alarm feigns to deactivate itself, but in fact it discreetly sends a distress signal by telephone to the security company or to persons previously designated by the owner.fact

Based on the demand and development trend of high-end smart TVs, a somatosensory game controller based on HID

 specifications is proposed, which is applicable to the design and implementation of intelligent remote controllers. Based on the analysis of various functional modules of the nifty remote controller, a hardware circuit scheme implemented by the somatosensory game controller is designed. According to a custom packet format, a software solution for implementing the somatosensory joypad with input and output functions on the RF transceiver side of the smart remote controller is described. The RF transceiver side of the smart remote controller and the television is described in detail. The communication process 

ultimately realizes the functions of the somatosensory joystick.

USB (UNIVERSAL SERIAL BUS) has the advantages of high speed, low cost, low power consumption, plug-and-play, and easy use and maintenance. With the gradual expansion of USB applications, USB devices are now not only connected to the computer peripherals. The device's standard input/output, it also becomes the standard input/output of smart TV connection peripherals. HID is an abbreviation of Human Interface Devices, which is a human-machine interface device. It is a machine class first proposed and supported by the USB protocol, and is also the most widely used type of USB device. Typical HID devices include a keyboard and a mouse. The USB serial bus specification specifically defines the HID specification as long as the device complies with the HID specification, which is the HID device. The operating system ships with a driver for HID. The user does not have to develop a cumbersome driver. This allows HID devices to establish communication with the operating system quickly and easily.

 

These benefits make HID devices have also been more and more widely used in the field of smart TVs. This paper is to study the design and implementation of six-axis somatosensory game controllers used in stylish remote controllers based on HID specifications.

 

The smart remote controller composes of two parts—RF transmitter and receiver (Dongle). The remote controller and the Dongle terminal use the RF communication protocol to communicate. The Dongle terminal connects to the TV through the USB interface. They utilize the USB protocol communication. According to the HID specification, an HID somatosensory joystick with input and output functions is simulated on the Dongle side to communicate with the TV through the USB protocol so that the remote controller and the somatosensory joystick are grouped into one.

 

After the Dongle side and the remote control side paired successfully, communication was made between them. The turning on and off of the somatosensory joystick function in the remote control is mainly achieved through the feedback information about the television. When pressing the somatosensory switch key on the remote control, the TV sends a feedback message immediately, so that the somatosensory switch on the remote control is illuminated, the somatosensory joystick function is turned on, and the user can use the remote controller to experience a somatosensory game. The TV cell is called according to the progress of the game. The sensor module, vibration module, and audio module in the remote controller realize the interaction between the remote controller and the television; when the somatosensory switch key on the remote controller is pressed, the television sends a feedback message to make the sensor switch indicator on the remote controller end off. Somatosensory joystick function is disabled.

 

The operation mode of the somatosensory game handles is mainly a key and a special action. In this system, the buttons required for the somatosensory joystick are multiplexed with the buttons of the remote controller itself, and the data of the special actions are translated into corresponding radio frequency transmitter keys. When there are distinct actions, they are sent out in the form of key keys. In addition, the special action function of the somatosensory joystick can be used to operate the TV portion of the glitzy TV. In the somatosensory joystick mode, the remote controller detects the swing of the left and right and the forward movement, and the next 4 by calculating the data of the sensor. The action can be used as a switching picture, music, etc. For example, fling to the right for the next song, fling to the left for the previous song, forward for the play pause, forward too quick exit.
