We are manufacturing a Vehicle Barrier and need the Electronics to control it. The barrier will move from position 0 deg to 90 Deg, using a 24 VDC motor We need a pulse to open the gate (from 0 to 90 Deg) and another pulse to close it (90 Deg Down to 0 Deg) When we send an open pulse the barrier should start to move fast, to open the barrier as fast as possible. About 10 Degs before (80 Deg when opening) the gate should down the speed to avoid damage to the barrier. This is posible because we have limit switch, either for open and for close (2 limit Switch). Once the limit switch have contact then we reduce the speed, our transformer have 2 different AC Voltages, these Voltages are redirected (the first one or the second one) to a bridge rectifier and then to the motor. We should change from high dc voltage to low dc voltage using a solid state relay. We connect the High voltage, high speed to Normally Close , low Voltage to Normally open and we will send the corresponding voltage using the common pin. The relay should be activated when the limit switch is reached. The Electronics should monitor the Motor, when the motor reaches a physical limit, the Motor will be stop by the electronics, we must monitor the current (or voltage) of the motor, so that if the barrier detect an obstacle should stop. We need a potentiometer here to increase or reduce the sensitivity of the opamp. There are 2 type of obstacles, the one that is for end of the move (I mean at 90 deg we have a physical obstacle inside) or, if the gate is closing and someone is in the middle of the road, we should detect the obstacle and open again the gate. This is to avoid permament problems to the gate or damage to cars. We also need some security rules. 1.- Infrared lights, we need a Normally close switch here, if this switch is open then the barrier should not operate. 2.- Immediate Close. We need this feature to automatically close the barrier when someone enters. I mean, we push the open switch and then , when the car is inside the barrier will automatically close the gate. But we need to put attention about the state of the infrared switch, we cannot close the gate if the Infrared switch is open. We need these inputs. Common - used by some functions. Close Port Open Port Infrared Port Immediate Close Port Common Limit Open Limit Close Limit Outputs GND Red Port Green Port Blue Port (the 3 above is to be used with a Led Strip). These 3 port must be driven with a PWM Transistor each one 24 VDC (For accesories) Would be great to have a debug port, either Bluetooth, Wifi. RJ45 Ethernet.

Hi, I hope you are doing well. I am expert in embedded system design and development. I have worked on gate control project. I read your project description and here is my review. I understand that you wish to open gate and close it. While opening the gate you want to open it as fast as possible and slow down at 80 degree. If we use DC motor with DC supply or DC batteries then we can slow down the speed using relay so we will not need different AC Supply. We can monitor and current drawn by motor and try much as possible to avoid damages or issue. I have understood your requirement and I am fully confident to execute this project successfully. Looking Forward, Khawaja

Do you have any recommendations to make this project run successfully? Yes. Please read my proposal, that allows more than 300 characters. Proposal: Hi, The main part of the project is to develop a closed control loop, in the simplest form a PID controller. I would suggest to disregard the High Voltage a low voltage AC with two rectifying bridges. You only need one, the voltage rated for the DC motor (24VDC). A PWM controlled power transistor can switch on and off fast enought that the mechanics (motor) will act a low pass filter, like if it had a lower voltage applied. For the calculation, the power will continue to be integral of Voltage and Current. Since the PWM is software controlled, I can provide to the motor a wide range of voltages/current/power -> Force. To reverse the movement, another channel with reverse voltage would be in place. You didn't tell how you would detect the obstacle. I would suggest to measure the current drawn by the engine. It reaches its peak when the engine is not rotating. My propposed architecture At the heart a uC (like atmega). Easy to programm and plenty of support available on the internet for you to tweek if necessary. The UC would be responsible for the communication and state machine of the board. To control all the PWM signals simultaneouly, I would use a dedicated IC (PCA9685). The uC has ADC. Resistive voltage dividers should be used when measuring voltage outside the [GND, VCC] range. To measure currents, we can use a low resistor and measure the voltage drop. The infrared beam should be on a different boards. No more space to write. .. Hope to hear from you.

1. REGARDING BARRIER MOVEMENT - you have mention about limit switch. limit switch is a fixed contact generally used for restriction but not for continuous monitoring for more precise and reliable method use encoder. you can control perfectly. Proposal: 2. actually we need two relays one for switching motor ON/OFF another for switching voltages for speed control. 3. Relays with opto coupler can used instead of SSR as they are cost effective and suffice your requirement. when encoder reaches its counts then automatically relay will be activated. 4. if we use encoder when motor is behaving abnormally we can sense it from the movement as if there is there is any obstacle for motor motion. encoder stops counting the steps from which our micro controller understands motor malfunctioned or obstacle and with alert user with red light and a buzzer and prevent damage by cutting of power supply to the motor. Regarding sensing we have numerous ways to so that, we can help you in designing a more reliable and sophisticated equipment with our expertise and we will show you the whole simulation before we actually try on hardware. If any modifications can also be simulated and displayed for your better understanding. you can go through our previous employer review on how we improvised his idea. there are many points we can improve in the process and i guarantee it to be completed in 3 working days. Looking forward t
