Description

Transparent perforated non-touch panel using light beams

This invention in the field of electrical engineering.

With the pervasive use of mobile phones and their touch screens, there have been changes in users' tastes and requests for easier use of electronic devices have increased. Elevators, like other electronics, were no exception. Therefore, panels were produced in the world that have touch keys instead of pushbuttons

To increase beauty, comfort and longevity were more.Optical touch panel technology Touch panels are produced with various technologies, one of which is Infrared or Infrared technology. The technology uses infrared transmitters and receivers to detect the location of the user's finger or stylus on the screen.

Infrared optical touch systems have a much longer lifespan than other types of technology (such as thermal, capacitive or resistive, and magnetic). The reason for this is the lack of contact between the pointer and the touch system. In this method, instead of using touch layers on the screen, infrared transmitters and receivers are used, which are installed around the screen as a matrix. These transmitters and receivers make optical (infrared) communication with each other as a transmitter-receiver pair.

The technology of this product may seem simple in appearance, but there will be major challenges to implement it up to the stage of industrial and applied production. A major challenge in the production of this product is the small space for designing control circuits with Get parts available through external sources. In fact, managing each of the transmitters and receivers embedded around the screen using microprocessors distributed in a narrow strip connected to these components is a complex and difficult task.

Another challenge is the systematic aggregation and processing of information published across the circuit, which must be done in a limited time of a few milliseconds for each horizontal-vertical sweep.

Also, the possibility of supplying the required power to the product without the use of an adapter or battery and only using the current available in the USB port of the computer, is another challenge that must be used using the best design for optimal current distribution and time division method. The main problem is to use lamps that have some infrared rays when the sun shines on the panel screen, which makes this type of panel inefficient. Also, the intense light of lamps, especially IR, interferes with its system.

There are other models of non-touch panels that are equipped with motion sensors. This type of panel, due to its high sensitivity, can cause errors with the possible movement of people. Also, for panels that have multiple and close keys, such as elevators, there is an error. Ziad moves close to the key.

Today, the prevalence of dangerous viruses in the world has increased, such as the corona virus, which is a problem at the community level
It has created a lot for people in all sectors. This new disease is a contagious disease of touching objects that the virus stays on objects for hours to days. Therefore, when using public services such as elevators, ATMs, etc., the virus may be transmitted to the body.

For this reason, we designed an invention that does not need to press the keys of the devices, and it is enough to point to the existing holes to perform the desired activity using the light beam and without touching any part. This design consists of several major parts that this product has finally been achieved.

Due to the fact that various diseases can be transmitted by touching objects. In this regard, the possibility of transmitting the disease in public places when using public transport is very high, especially with the introduction of the corona virus, which easily remains on objects, and the risk of death increases with non-compliance with hygiene standards. In general, by pressing the elevator keys, shift keys, etc., in addition to their permanent breakdown, it is also possible to transmit the disease. The device we have designed is to remove the contact buttons and increase hygiene by placing empty compartments on the panel to operate using light beams without any contact. So that by inserting a finger inside this compartment without any touch, the activity starts and the device detects the desired button.

The design of this tool, considering the necessity and sensitivity of this tool to prevent the spread of dangerous coronavirus and other viruses, will bring a good market for this product in all public centers and home elevators..

In recent years, due to the increasing work process of people in society, social life is moving towards
Increasing productivity has led to significant progress, which is a breakthrough in all Industries as well as electrical equipment are the factors affecting that need. Invention designed to

In general, it has a precise structure and at the same time it is very practical. In fact, this design consists of several major parts that this product has finally been obtained.

The plan generally consists of several parts, which are:

The first part of the internal panel has several keys:

Transparent perforated panel, transmitter, receiver, optical filters, inlet holes, display, audio circuit, microcontroller circuit, light intensity comparator circuit.

The second part of the external panel with a key:

Transparent perforated panel, transmitter, receiver, optical filters, inlet holes, 83 kHz modulation, tripod sensor, circuit box.

The function of the first part of this system is that there is a frame around the transparent perforated panel in which the transmitter and light receivers are located, these transmitters and receivers are parallel to receive the transmitted light beam immediately Also, in order to prevent noise and excess light from entering the system, we designed optical filters that are opaque in nature and have a hole on them so that only the light sent by the sender is received and does not receive noise to increase the accuracy of the device. And if the person inserts his finger into the hole of his choice, the beam sent from the receiver is cut off and as a result the beam receiver The light detects the location of a person's finger through a microcontroller that detects rows and columns

As a result, it sends the necessary commands to the next circuit to activate the desired key. When the desired key is activated, the light ring around it will light up and its color will be different from the background, and its special numbers or modes will be displayed on the built-in display. At this time, the audio circuit starts working and announces the name of the destination or the entered number. The control panel circuit includes a microcontroller circuit and light intensity comparators and a display to display the intensity of light variables and external noise intensity, a key circuit including relays or in the form of MOSFET or transistors to reduce the volume of the circuit. The system has a single key (pager) and is generally suitable for external elevator buttons on each floor that can be placed next to the main key. This system has differences with the main system and several keys. This system works with light reflection. It is different from the first part, which activates the receiver when the light is turned off. This light is reflected and the receiver sensor detects that the switch should be activated.To eliminate IR optical noise, we use optical filters, which are slightly different from the filters used in section one, so that the noise And the light enters the first filter hole obliquely and in the second filter it does not find a way out and disappears. goes. In this filter, there is an opening for light entering from the receiver to be activated when it reaches the receiver. We

To build this panel remotely, we can use the first method using filters designed and designed, and the second method using 83 kHz modulation with a tripod sensor that automatically removes noise. The pager system consists of a glass panel, on which there is a light hole and at the bottom is connected to the circuit box.

This system generally has a structure derived from internal research and development and at the same time is practical, which has unique advantages and goals that have clearly introduced the capabilities of this system.

Some of these benefits and goals include:

Reduce the risk of infection and transmission of viruses such as coronavirus

Ability to install inside and outside elevators

Ability to install to take turns

Easy to use and beautiful

Having economic benefits

Performs accurately when exposed to direct sunlight

No noise when moving

Examples

This system has several parts so that the person selects his key by placing his finger inside the hole and without any touch. After selecting around the key, a shadow of different lights with the background is created, even the person can choose for himself. It can use several keys that are displayed on the screen. Also, by entering a special code and pressing the information, the information is broadcast from the audio system and even has the ability to record to send a message at a specific time. The user can also access the settings system easily by entering its special code. Also, to use the second part or the same pager, after inserting the finger into the light hole, it reflects the light sent from the transmitter.

The reflected light enters the filter and reaches the receiver and the key is activated.
