The weight measuring units are weight measuring sensors, are arranged on a track or a track plate below the carriage at the parking position, are longitudinally and uniformly arranged in two rows corresponding to the track position, are symmetrically arranged at the left and right sides, and are arranged in the same form. The weighing sensor can record weighing data in real time and complete transmission every 500 milliseconds.

2. An operation module:

the operation module receives the weight information of the carriages, calculates the weight of each carriage, and sends the weight information of each carriage to the central processing unit of the station. The operation mode of the operation module comprises two operation modes of scattered operation and centralized operation:

(1) and (3) dispersion operation:

as shown in fig. 2, the operation module may include a plurality of operation units, each operation unit is disposed near each weight measuring unit of each car, one operation unit corresponds to one weight measuring unit and is connected to each other, each weight measuring unit measures the weight of the car corresponding to the position of the car and transmits the weight to the operation unit corresponding to the weight measuring unit, and the operation units accumulate the weight measured by each weight measuring unit of the car where the operation unit is located and transmit the weight information of the car to the central processing unit.

Each compartment is provided with a collection point, each operation unit of each compartment sends respective calculation result to the collection point, and the collection point sends all the calculation results to the central processing unit.

(2) Centralized operation:

the computing module is provided with one position and is arranged near the central processing unit, each weight measuring unit of each carriage sends the carriage weight corresponding to the carriage position to the computing module, and the computing module computes the weight of each carriage and sends the weight to the central processing unit.

3. A central processing unit:

the central processing unit receives the weight information of each carriage, converts the weight information into the number of people in each carriage (the weight of passengers is averaged to be 60-70 Kg), and displays the weight information through the display module of the next station. When the operation module adopts a distributed operation mode, the central processing unit receives the weight information of the carriages transmitted from the operation unit of the collecting point of each carriage. When the operation module adopts a centralized operation mode, the central processing unit receives the weight information of each carriage sent by the operation module.

The central processing unit comprises an information processing module which is positioned in the station equipment room and processes the received information by taking each carriage as a unit. When the weight of the carriage is used for obtaining the crowding degree of the carriage, because the weight of the carriage is relatively fixed when the carriage is in no-load, the weight difference between the weight of each carriage and the weight of the train under the no-load condition is collected to be the weight of people and articles in the carriage, and then the passenger carrying rate of the current carriage can be calculated according to the estimated value of the average weight (the weight of passengers is averaged to be about 60-70 Kg/person) and the number of the limited passengers of the vehicle. The accuracy of the system is influenced by factors such as large weight difference of passengers at different age groups and whether the passengers carry luggage.

Load factor = (actual load-no-load)/(overload load-no-load) × 100%.
