All be provided with lighting apparatus on each seat.
Another technical scheme of the present invention is, above-mentioned subway carriage vacant place detects the detection method of display system, and concrete steps are:
Step 2, microprocessor receive and show from the room information of main control computer and by display screen;
Step 3 judges whether n equals zero, if equal zero, then enters step 7, otherwise reads the lighting apparatus that is numbered n, enters step 4;
Step 4 judge the state of photodiode in n the lighting apparatus if photodiode is in conducting state, then to enter step 5, otherwise n is returned step 3 from subtracting 1;
Step 5, m is from adding 1, and n is from subtracting 1;
Step 6 is judged whether n equals zero, and enters step 7 if n equals zero, otherwise is returned step 4;
Step 7 sends value and the coach number of m, and makes m equal zero, and n equals a and returns step 2 then, and a is a seating capacity.
The invention has the beneficial effects as follows,
1. subway carriage of the present invention vacant place detects the seat operating position in the monitoring subway carriage that display system can be real-time, makes the passenger can find vacant place in the subway carriage very easily, has avoided the waste of resource, has also saved passenger's time simultaneously.
2. the display system that detects at subway carriage of the present invention vacant place adopts the total line traffic control of CAN to realize data information transmission, and the CAN bus has stronger real-time and reliability, and all nodes can be received on the CAN bus, reduce the quantity of wire harness; Adopt the information acquisition of photodiode realization to each seat operating position, with low cost.
