Embodiment Construction
[0029] The present invention will be further described below in conjunction with accompanying drawing.
[0030] Such as figure 1 As shown, the system of the present invention includes: a control master station and a plurality of control sub-stations. The control master station is the control center, and each control sub-station controls a corresponding set of signs. The set of signboards includes right-way signboards and left-way signboards. Each sign includes a normal traffic light, a left traffic light, a right traffic light and a fault light.
[0031] The RS485 communication method is adopted between the control master station and the control sub-station. Control master station capacity: support up to 15 groups of control sub-stations, use the dial switch to select the corresponding control capacity of the control master station.
[0032] The control master station includes four-way switches, four-way relays and a four-position dial switch; the control sub-station inclu...

The invention relates to a system and a method for remotely controlling tunnel indicator boards. The system comprises a control main station, a plurality of control substations and a plurality of groups of indicator boards corresponding to the control substations; the control main station is a control center; a communication mode RS485 is adopted between the control main station and each control substation; each control substation controls a corresponding group of indicator boards; the control main station comprises a four-way switch, a four-channel relay and a four-digit toggle switch; the four-way switch is used for respectively and correspondingly controlling a normal running indicator light, a left running indicator light, a right running indicator light and a fault indicator light through the four-channel relay and is connected with a switching push button of a controller panel; a toggle switch is used for selecting control capacity of the control main station; each control substation comprises an eight-channel relay and a version returning indicator light of the eight-channel relay; and the eight-channel relays are used for respectively and correspondingly controlling right-lane indicator boards and left-lane indicator boards. The method is simple in implementation and less wire harnesses are used.
Description
technical field [0001] The invention belongs to the field of computer application technology, and in particular relates to a remote control system and method for a tunnel sign using embedded computer technology and computer signal processing technology. Background technique [0002] The lane indicator is set at the entrance of the tunnel and inside the tunnel. The red "X" or green "↓" light above each lane indicates that the lane is closed or opened, and it is a traffic signal that only directs vehicles traveling in this lane. In order to enable the tunnel to safely drive in the opposite direction under abnormal circumstances, the lane indicator adopts double-sided type. Lane indicators are generally set in the first group at the depth of 3-10m at the tunnel entrance. After entering the tunnel, according to the curve, height and visibility of the longitudinal section of the tunnel, it is generally about 500m apart. [0003] In long tunnels, the principle of setting the spa...
