Ability to connect door switch for exiting without authorisation #72

Closed spratters closed 3 years ago

spratters commented 8 years ago

Hi there, We currently have a few Pis with PiFaces running Leosac, and all is working fine with a Wiegand reader. The trouble we're having is enabling the user to exit through the door without using a card, but by pressing a button. The exit button we have has 4 wires to it (2 x NO and 2 x NC). Is there a possibility of something like skipping authorisation and going directly to the doorman module when the button is pressed. It would be handy to be able to use to doorman to keep the door unlocked for a certain amount of time when exiting. Thanks for your time.

Hello,

First let me tell you that I'm not familiar with push button and their wirings. Correct me if I'm wrong, but I'm going to assume that pushing the button translates to a GPIO interrupt, that would be recognized by the piface_digital module.

Currently the doorman module is only able to handle message from the authorization module. Indeed you specify auth_contexts when configuring it.

I don't know if you guys write C++, but if you're interested in submitting a pull request to support this use case, here are a few pointers:

It would be handy to be able to use to doorman to keep the door unlocked for a certain amount of time when exiting.

This is already possible. 

<action>
  <on>GRANTED</on>
  <target>gpio_door</target>
  <cmd>
    <f1>ON</f1>
    <f2>2500</f2>
  </cmd>
</action>

The <f2> parameters controls the duration of the ON state. This is documented here.

Thanks @xaqq, I work with @spratters. We're not C++ developers but PHP developers who are happy to stray from our comfort zone :)

We've been playing about, but not getting far. You're right that the button translates to a GPIO interrupt, that is recognised by the piface_digital module. If we try connecting one button wire to ground and one to a spare input pin (the "normally closed" wires), "listening" to it in the gpio config and purely as a test, setting the wiegand reader low pin to this, it does trigger the wiegand module when pushing the button. Obviously it now cannot read a card properly as the module is not connected to, but this does seem to indicate how the interrupt works.

We'd rather not need to change code or build from source. Basically we have configured two wiegand readers. One is real, and one is fake. The fake one always reads the "button push" as a card like this:

Source Name: VIO_FAKE_WIEGAND
Source Type: WiegandCard
Number of bits: 26
Card id: 00

Adding that card (00) to the auth file does then follow through to the door opening. The "real" reader is also reading cards ok and unlocking the door correctly. The only issue we're having now is that the "real reader" seem to trigger a read from both. As in, if we scan a card, both readers try to read the card, the result is the "fake reader" giving us a card of 00:00:00:00:00:00:00 (which the auth does not allow). The "real reader" gives us the correct output and unlocks the door.

The button ("fake reader") when pushed only triggers a read on the fake reader, so reads 00 which we have in the auth file and therefore the door unlocks. The "fake reader" (button) does seem to get triggered twice per button push. I'm guessing that this is when it goes in and back out, but this doesn't seem to cause a problem.

This means that in practise the door locks and unlocks when it should, but when scanning a valid card we always get both the GRANTED and DENIED run (so we get our error sounding beep, but the door does unlock).

Can you help with this? We'd really appreciate it if you can :)

Is it just a config issue which is causing both readers to try to read a card when we scan a card? Our kernel.xml is as follows:

Hello @violuke ! Its a nice workaround you got there :)

Taking a look at your configuration, it looks correct. It's odd that the FAKE_WIEGAND reader detects a 52 bits card when scanning a card. I know I've had some trouble with interrupt triggering infinitively when I didn't wire the reader's ground properly. I'm not sure this is similar, because you see spurious interrupt only when the "real reader" reads something.

I would say this is a wiring problem, but I can't be sure. I recommend you enable the MONITOR module. It's not very clean and is spammy, but it may help diagnose the problem.

        <module>
          <name>MONITOR</name>
          <file>libmonitor.so</file>
          <level>150</level>
          <module_config>
            <file-bus>/tmp/log</file-bus>
            <verbose>1</verbose>
          </module_config>
        </module>

You will get spammed for every interrupt that the system detects. If when scanning a card you see some interrupt regarding the exit_button it may confirm a wiring problem. Feel free to post the log file after enabling this module because it may not be easy to read.

Thanks @xaqq, @spratters and I have been looking at this again this morning. We've set up the MONITOR module and will put the logs at the bottom of this message. It seems that an interrupt is wrongly coming from the exit_button pin when the card is scanned. We've removed and re-wired all connections and they do all seem to be solid and neat and the same thing is still happening. We also tried moving exit_button from input pin 7 to 6 and adjusting the config, but exactly the same thing happened. We also tried changing the earth used by the exit_button but that made no difference (as expected).

I'm not really sure what to do now? It is a workable solution and we're in a hurry, so we'll probably have to stick with our work around for now.

Ideally there'd be a new really simple module for a push button which simply listened to the interrupt on a single in pin and told the doorman GRANTED (no authorisation required). I guess it might be best if it could also debounce the button push (as I think this is why the button push fires multiple times (usually 2, but I think I have seen 3)). I'll try and have a look at this myself at some point but I'm not likely to have it working soon. Is this something you could help with?

Below is the logs (with exit_button on pin 6):

Hello, Thanks for testing this.

Looking at the log file, we indeed see interrupts coming from the exit_button pin. While it's possible that this is software issue, it really seems like the interrupt are really getting triggered. I have no idea why though.

I can think of one more test you could do. The Piface has 4 integrated push buttons, that IIRC map to input pin 0-3. Could you try removing your hardware button, and use the Piface button instead. If the exit_button as-a-piface-button doesn't receive unwanted interrupt, this may point to a wiring problem. Otherwise it may point to an other issue.

Ideally there'd be a new really simple module for a push button which simply listened to the interrupt on a single in pin and told the doorman GRANTED (no authorisation required). I guess it might be best if it could also debounce the button push (as I think this is why the button push fires multiple times (usually 2, but I think I have seen 3)). I'll try and have a look at this myself at some point but I'm not likely to have it working soon. Is this something you could help with?

Either something like this yes, or improving the doorman module so that it can listen to GPIO interrupt would work too. That's something worth doing indeed, however I can't give you a timeline. WRT debouncing the button, I don't know if this is possible. Maybe ignoring additional interrupt in a given timeframe could work. I don't really know.
