How to organize a bus access control system?

Question

Automation

A transport enterprise (ATP) transports personnel of several enterprises along one route. Enterprise A (conditionally) is the main customer, enterprises B1, B2, .. BN, as well as B1, B2, .. BN are its contractors. Enterprises A and B1, B2, .. BN have contracts with ATP, enterprises B1, B2, .. BN do not. It is necessary to organize the management of access to buses in such a way that the personnel of enterprise A have access to some buses, the personnel of enterprises B1, B2, .. BN - to others, and the personnel of enterprises B1, B2, .. BN and random passengers - neither to one of the buses.
Enterprise A operates an access control and management system (passes are EM-Marin standard identifiers). The personnel of all listed enterprises have passes. An enterprise from category B can move to category C and vice versa.
It is not necessary to use passes - this is one of the options. The advantage of the solution is that the pass is always with the employee. You can use options that use barcodes, QR codes, etc.
The solution of the problem "on the forehead", i.e. the use of ACS components (readers, turnstiles, etc.) of enterprise A is not economically feasible.
Suggest a simple and ingenious solution to the problem. Perhaps it will not have all the functionality of a full-fledged ACS, the main thing is that it be effective in the existing conditions. Thank you!

Answer 1

You want to eat a fish and not choke on a bone ...
How do you imagine, in the absence of turnstiles, to restrict the passage of a person into the passenger compartment of the bus?
Is it possible to distribute bits to drivers?
Then gouache is generally needed to make passes of different colors (color for A, for B and for C) and so that the driver, seeing a pass of a different color, immediately hits the jug with a bat ...
It will come out cheap and cheerful.

Answer 2

do you need turnstiles? well, then a notebook in a cage for 48 sheets, enter in neat letters the passport data of those who can, and then put a stamp on their foreheads. If anyone in the cabin does not have a stamp on his forehead, beat him up and kick him out!
Let's start by defining the conditions for solving the problem, because you can hire the Liechtenstein army to guard the buses, but I'm sure you will have reasons to abandon such an undertaking.
1. What is the cost of system development? Something ready - about zero, to be smart - from zero to infinity.
2. How much can this system cost? Turnstiles are expensive, and a notebook with a stamp does not meet certain conditions. We also need to find a compromise.
3. The cost of operating the system. You can spend a trillion a month, of which 40 to the conductor, the rest for a premium, or you can buy turnstiles that will have to be serviced every n times
4. Spec. requirements? Simplicity is understandable. What level of security should be? printing monthly travel cards on leaflets is quite inexpensive, but everyone can do this, even an employee of organization B.
In addition, you need to understand how the process of loading and unloading takes place, what working conditions are. For example, loading people through the front door, closing the rest, you can assign the duties of a ticket bouncer to the driver. Then you need either electronic passes and readers, respectively, or ordinary passes, but with a list or updated every month, for example.
For some reason, I advocate for electronic passes, at least based on nfc tags. Then special smartphones with special software issued to drivers will be suitable as a reader. But to protect against copying, special. the program will at least have to read the code and determine the client, overwrite the new code on the NFC tag, by which it is possible to uniquely identify this very client, deactivate the old one and synchronize all this with the server. All this will result in some cost of software development, device purchases and monthly maintenance (internet for smarts, server maintenance), but will ensure that no category B worker enters the bus, and also provides good flexibility. Perhaps it will be cheaper to use a ready-made pass system without creating a new bike.
QR codes are cheap to use, but no security or convenience. It is easy to lose a piece of paper, but for protection you will have to generate new tickets every time and give them to category A and B workers.
Another good option is sending SMS with individual codes. Despite 2016, not everyone has smartphones, but there are definitely phones. At the same time, these codes can be one-time, which will not allow them to simply give them to category B friends who also want to ride. But even here convenience is not in the first place - the phone can be discharged or lost.

Answer 3

there is such a device, authorization systems, several biometrics, face detection, rfid tags at 125 kHz en marine, only buses need the Internet or at least temporary access for min 12 maximum to download and upload information about visits and access levels if necessary. You don’t have to pay money for software in Russian (usually this is the most expensive in the estimate) and is perfect for ACS organizations and the open code (remake it to your needs, for money) also has a working time record, I don’t know such devices were installed in cars. ZKTeco, I'm sure there are such systems everywhere, at least in very large cities, the price of the issue is from company to company, but I don't know another ACS system with free multifunctional software.
If you know other similar similar systems with free full-featured software, people do not hesitate to write, at least I will be very glad to gain experience from each other.

Answer 4

2 seconds turn into 8-10 on average

I agree with you - absolutely not an option. Even with manual gap control, the graphs are strongly shifted "to the right". Not a specialist in this field, but another question is how the equipment will work in the twilight, at low temperatures, etc...

Answer 5

Ideas, ideas...
There is the simplest solution, but with ACS elements:
The reader at the entrance at the door of the driver's cabin, the passage sensor on the step and the confirmation button / second reader a little further. Controller, even the simplest type Z5-R + indication lamp.
Pros: maximum simplicity.
Cons: You may need additional devices that do not affect the zero configuration. The participation of the driver is required if the turnstile is not used. Entrance is only through the first door.
In general, yes. The technical configuration of the equipment can be discussed, all the same, you will not take into account all the conditions. My mail is tintagel (a well-known creature) yandex.ru or write to the site.
There were also thoughts about only seats with confirmation of seat IDs, but there is again a driver, but the entrance is through all the doors.
And two-factor identification: registered at the bus stop, got on the bus.
Good luck.
