Railway carriage watering measuring control system device and method for metering and monitoring watering

[0039] A water metering management system for railway passenger cars, such as figure 1 Shown: including m remote controllers Ⅰ1, Ⅰ2,...Im, n sets of on-site hosts Ⅱ1, Ⅱ2,...Ⅱn, 1 set of computer management system, the value range of m and n is: n is between 1 and 1000 Integer, m≤n, that is: one remote controller can be used to control one set of on-site hosts, and one remote controller can also be used to control two or more sets of on-site hosts. The common value ranges of m and n are : n is an integer between 1 and 300, m≤n;

[0040] The remote control (such as figure 2 (shown) is composed of a control center 13, a keyboard input unit 14, a status indication unit 11, a wireless data transmission unit 12 and a power supply unit 15, and is mainly used to issue instructions for turning on or turning off the specified water tap;

[0041] The components and functions of the remote controller are:

[0042] Control center 13: using a single-chip microcomputer, responsible for the

[0067] A method for measuring and monitoring water supply by a railway passenger car water supply metering management system device, which uses the railway passenger car water supply metering management system described in Embodiment 1, and uses remote control software, on-site host software and computer management system software, On site, the water supply personnel issue commands to specify the water supply cocks to turn on or off the water through the remote control, and the on-site host computer recognizes the commands sent by the remote control, and controls the corresponding water supply cocks to turn on or off the water after confirming the commands, and at the same time records the opening and closing of the water. The cumulative flow of water flowing through the hydrant at the time of shutting off the water and during the period forms a record file; the computer management system transmits the files recorded by the on-site host to the computer database through the data tra
