Complex of wireless control on a radio channel (WCR)
The complex of WCR is intended for remote work with a portable control panel (PCP) of the road controller by the inspectors of traffic and command structure of GAI. The complex also can be used for wireless control on a radio channel by automatic control system means, operated traffic signs (OTS), for example, programmed indexes of speed, a board information on the entered or modernized objects.
The complex consists of the operating transferring module placed in a rod of the traffic inspector (see the picture), and the board of radio reception installed in a portable control panel. The rod power supply –built in accumulator with additional charge from a network 220 V/50 Hz. Time of continuous work more than 10 hours. It is possible to produce the transferring module in other tiny case with power supply from battery. Access control to a complex of the WCR is carried out by means of identification keys iButton with the unique 64-bit code which is read out at a contact of the metal case of a key with the input reader of the WCR. A key contains a data on its user (surname) and 32 bytes of the additional information defining region and time of resolved use of a rod the WCR for road controllers control. The key is fixed on a trinket or a plastic card with a photo and a surname of the user.
Programming of identification keys with instructions of region and time of resolved use of a rod WCR is made with giving to the guard for traffic control in a definite are in a city in department of GAI with the help of the computer.
Activization of the transferring module is made by a contact of "tablet" of a key to reading out devices of a rod and PCP. By reading out information from the key iButton PCP checks the admission of the inspector to control of the road controller at a crossroads. With its confirmation the radio communication of a rod of the inspector of GAI with PCP is installed. The complex of the WCR is ready to work. Transport traffic control is possible at a crossroads from any point within a steady radio communication of a rod with PCP of the controller (till 100 m).
There are 2 buttons of control of the road controller on the rod handle:
The button 1 switches off the current program of coordination of traffic lights objects of a crossroads and includes a mode of wireless control on a radio channel from the activated rod. Repeated pressing of the button 1 returns the controller in an initial condition.
The button 2 allows to switch the traffic lights objects of a crossroads to the following phase of the current program of coordination depending on a transport situation at a crossroads. The inspector can synchronise a condition of traffic lights objects with the operating gestures at a crossroads with a help of this button of a rod.
It is probably to have other function of rod buttons.
The mode of remote activization PCP on a radio channel on the move (without a contact of "tablet" of a key to the reading device) with use of cryptographic codes of access is provided for GAI administrative board. The transferring module (can have other case instead of a rod) has the third button 3 for GAI administrative board in addition–«to include special phase of controller », providing priority passage of a crossroads.
The transferring module can be equipped with other buttons and remote control means of the road controller with the offers of users of a complex WCR.
All operating influences on a radio channel with instructions of time of their execution and an identification key of the inspector of GAI are recorded in non-volatile archive of the road controller. The archive of the WCR can be read and printed on the computer.
