摘要： PROBLEM TO BE SOLVED: To surely detect fall of a person or an object into a railway track by providing a detection means outputting a fall detection signal when a prescribed change is generated in physical quantity in a detection area detected when a vehicle stops at a station by the entering into the detection area by a person or an object. SOLUTION: Each detection area V1 and V2 of detectors 54 has an extent in a railway track direction as each detection area V1 and V2 becomes the lower part by directivity of the detectors 54. Light emitted from the detectors 54 is projected on the whole area of a railway track surface corresponding to the lower surface of each detection area V1 and V2. By mounting the detectors 54 on both vehicle tip parts 51a and 52a, prescribed areas of a gap between both the vehicle tip parts 51a and 52a are always made detection areas in these detectors 54. The positional relation of the detectors 54 and the vehicle is always constant and fixed. Therefore, a fall of a person into a railway track can be detected from the prescribed areas of the gap between both the vehicle tip parts 51a and 52a.

摘要： PURPOSE:To early find out re-skid immediately after re-adhesion by a method wherein current speed data are inputted to a storage part and a skid control part, an average acceleration determined on the basis of the speed data stored till the previous time is inputted to the skid control part, and when wheels are restored to re-adhesion from skid, all the speed data are replaced by the maximum speed in the speed data. CONSTITUTION:Speed data V1 are determined by an arithmetic part 2 on the basis of a speed pulse obtained from the current speed of a vehicle and inputted to a speed pulse input part 1 and are inputted to a speed data storage part 3 and a skid control part 5. The speed data storage part 3 outputs speed data V2 to Vn obtained till the previous time, and an average acceleration computing part 4 computes an average acceleration alphabeta and inputs it to the skid control part 5. When it is detected that wheels are restored to re-adhesion from skid, all the speed data in the storage part 3 at this time are rewritten by the maximum speed Vmax determined by an arithmetic part 6. According to this constitution, re-skid immediately after the re-adhesion is found out early, braking is quickened and damages of the wheels and rails are prevented.

摘要： PURPOSE:To obtain an antiskid unit for achieving readhesion positively even upon duration of instable state where the direction of wheels is not settled even upon cessation of skid. CONSTITUTION:The antiskid unit 20 for vehicle comprises a skid detecting section 21 for detecting skid of wheel to produce a brake force decreasing signal (a), a skid cessation detecting section 22 for detecting cessation of skid to produce a brake force sustaining signal (b), and a recovery detecting section 23 for detecting eventual recovery of wheel speed to produce a brake force reset signal (c). A time interval after provision of the signal (b) from the skid cessation detecting section 22 before provision of the signal (c) from the recovery detecting section 23 is then measured and when the time interval thus measured exceeds a set time, a signal (e) is delivered from a timer circuit 25 to a circuit 26 for forcibly reducing brake force.
