The last few days we’ve been talking about how to manage tool access control.
The vague plan is to have a board that controls a load of contactors, and a board and RFID reader at each station, connected via a multi-drop RS485 bus.
Going a bit mad here but could there be an interlock system so you dont get your fob back till you return the tool ( I know this can not work as you often need more then one tool!)
But some mechanism of re-tapping to say yes I have returned the tool, a multi coloured LED on each control unit to say its out you need to fob it back in.
It will only be for the big floor standing tools in my opinion the battery and low risk tools should be uncontrolled , we are all grownups , and the more dangerous corded tools should be controed by turning off the power to the sockets that they plug into. This would mean that the router and the angle grinder ect will have 16a round pin. Plugs fitted
I feel that that if people have to be controlled anymore than the minimum for the H&S requirements they should not be in the workshop . We are all adults and should be treated and act as such.
I think a culture of putting things back is what we need.
Also: those fobs are front door and shutter access, we shouldn’t leave them where we can’t see them. This works for the laser cutter, as you need to be standing there.
These for override, one to lock out all the tools, one to bypass access control. Originally we planned to use one switch but that seems hard to source.
Okay no problem , it looked modular to me ,hard to tell on ebay but it did say addanl contacts are available on the site , so can be configured any way we want , but two switches will do fine
I think it has two single pole contains wich should be what we want , but really hard to tell pn a ebay site, but it may have needed a normal closed contact as well ad per the picture
The plan Joe has is to fit a RFID tag on them so all the power stations recognise the tool that is connected and the member swipes their tag and that controls access.
I am not convinced myself I think we are getting a lot more complex systems than we need.
Also on this point I was thinking Joe perhaps we should use 125Khz tags for the plugs so there isn’t interference between the two readers in each plug.
