Detailed Description
The present invention will be described in detail with reference to specific embodiments.
The invention relates to a method for judging the water flow in a water supply pipeline of a passenger bolt, wherein a water supply pipeline 1 and a main water supply pipeline 7 in a water supply system of the passenger bolt are respectively provided with a pressure collector, whether the water in the main water supply pipeline 7 flows or not is judged according to the pressure change collected by the two pressure collectors, and whether the water supply branch pipe 4 of the passenger bolt supplies water or not is confirmed.
The water supply system for the passenger bolt comprises the following components: one end of the main water supply pipeline 7 is connected with the water supply pipeline 1, and the other end of the main water supply pipeline is sealed by a blind plate 6 to form a blind pipe; the upper part of the main water supply pipeline 7 is provided with a passenger bolt water supply branch pipe 4 and a water supply valve 5.
According to the invention, a water supply pipeline pressure collector 2 is arranged on a water supply pipeline 1, a main water supply pipeline pressure collector 3 is arranged on a main water supply pipeline 7, and both the water supply pipeline pressure collector 2 and the main water supply pipeline pressure collector 3 are connected to a pipeline water flow judgment device 8 through a signal line 9.
The pipeline water flow judging device 8 comprises a data acquisition module 10 and a data processing module 11; the data acquisition module 10 acquires pressure signals acquired by the water supply pipeline pressure acquisition device 2 and the main water supply pipeline pressure acquisition device 3 at regular time through the signal line 9, converts the pressure signals into information with a uniform format and transmits the information to the data processing module 11, and the data processing module 11 compares the two pieces of information. The pipeline water flow judging device 8 further comprises an alarm module 12 and a power supply module 13, the alarm module 12 gives an alarm to the result of information comparison of the data processing module, and the power supply module 13 supplies power to the pipeline water flow judging device 8.
The pipeline water flow judgment device 8 makes the following judgment according to the collected information:
1. when the pressure of the water supply pipeline 1 is not reduced and the pressure of the main water supply pipeline 7 is reduced, the water in the main water supply pipeline 7 is judged to flow, and the water supply branch pipe 4 of the passenger cock is in a water supply state.
2. When the pressure of the water supply pipeline 1 and the pressure of the main water supply pipeline 7 are both reduced, and the pressure reduction amplitude of the water supply pipeline 1 is far smaller than that of the main water supply pipeline 7, it is judged that water in the main water supply pipeline 7 flows, and the water supply branch pipe 4 of the passenger cock is in a water supply state.
3. When the pressure in the main water supply pipeline 7 is the same as the pressure in the water supply pipeline 1, the water in the main water supply pipeline 7 is judged not to flow, and the water supply branch pipe 4 of the passenger cock is in a non-water supply state.
The method according to the invention is explained in further detail with reference to the drawings:
one end of the water supply pipeline 1 is used for water inlet, the other end of the water supply pipeline is used for water outlet, and the side surface of the water supply pipeline is provided with a main water supply pipeline 7. One end of the main water supply pipeline 7 is connected with the water supply pipeline 1, and the other end of the main water supply pipeline is sealed by the blind plate 6 to form a blind pipe. The upper part of the main water supply pipeline 7 is provided with a passenger bolt water supply branch pipe 4 and a water supply valve 5. When the water feeding valve 5 is opened, tap water sequentially passes through the water feeding pipeline 1, the main water feeding pipeline 7, the water feeding valve 5 and the passenger bolt water feeding branch pipe 4 and enters a train needing water feeding.
The water supply pipeline pressure collector 2 is arranged on the water supply pipeline 1, and the upper water main pipeline pressure collector 3 is arranged on the upper water main pipeline 7. The water supply pipeline pressure collector 2 and the upper water main pipeline pressure collector 3 transmit collected pressure signals to the pipeline water flow judgment device 8 through the signal line 9. The pressure collector adopts the following models: QDW90A pressure sensor, measuring range-100 kPa to 60MPa, and output signal of 4 to 20mA or 1 to 5V. The pressure sensor is small in size and convenient to install.
When water is needed to be supplied to the train, the water supply valve 5 is opened, water is supplied to the train from the passenger bolt water supply branch pipe 4, water in the water supply main pipe 7 flows, and the pressure in the water supply main pipe 7 is reduced. Because the pipe diameter of the water supply pipeline 1 is far larger than that of the main water supply pipeline 7, the pressure of the water supply pipeline 1 is basically unchanged or the reduction amplitude is far smaller than that of the main water supply pipeline 7. When the water supply branch pipe 4 of the passenger cock is not supplied with water, the water supply valve 5 is closed, the water in the main water supply pipe 7 is static, and the pressure in the main water supply pipe 7 is the same as the pressure in the water supply pipe 1.
By utilizing the pressure changes collected by the two pressure collectors arranged on the water supply pipeline 1 and the main water supply pipeline 7, the pipeline water flow judging device 8 can judge whether the water in the main water supply pipeline 7 flows or not, and confirm whether the passenger bolt water supply branch pipe 4 supplies water or not. The method solves the problem that the water meter cannot be installed on the main water pipe 7 of the passenger bolt of the passenger train with limited space, the volume of the pressure collector is small, the installation is convenient, and the method is convenient to implement.
The invention is not limited to the examples, and any equivalent changes to the technical solution of the invention by a person skilled in the art after reading the description of the invention are covered by the claims of the invention.
