Abstract

PURPOSE:To automatically calibrate a timepiece at a slave machine side by calibrating the timepiece at the slave machine side based upon the time displayed by the timepiece at the master machine side when data are transferred from the slave machine to the master machine. CONSTITUTION:Before an omnibus 10 is driven, first, a memory pack 30 is installed at a data collecting device 20 and a route starting button 26 is turned on. A data reader 40, when the prescribed data are transferred from the memory pack 30, calibrates the timepiece at the memory pack 30 side based upon the time displayed by the timepiece at the master machine side. The calibration of the timepiece at the slave machine side is executed at the time of either of the times immediately before the data are transferred to the master machine, or during the data are transferred or immediately after the data are transferred.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for recording data on a public bus or the like.

[Conventional technology] As a device for automatically checking the number of passengers getting on and off a bus, etc., a slave unit is installed on the bus to count the number of passengers getting on and off, and a master unit that processes the data collected by the slave unit is installed at the head office (sales office). )
There have been devices installed in the past.

The handset records data on the number of 41s passengers and the number of passengers getting off the train using optical sensors and the like, and has a built-in clock. And when operating the 5-pass,
The number of passengers getting on and off at each stop is counted, this data is aggregated on the main unit, and the results are used for route planning. For example, the above-mentioned aggregation results are used to determine the number of buses to be operated and to change routes.

By the way, in the above conventional example, the clock built into the handset has an error, and as time passes,
The error gradually becomes worse. Therefore, it becomes necessary to calibrate the clock. In reality, this calibration would be carried out by the driver of the bus, but in addition to his primary job of driving, the driver also calibrates the hill clock, so it is necessary to carry out this calibration work. The problem arises that the process is complicated.

"Objective of the Invention" The present invention has been made by focusing on the problems of the conventional device described above, and includes a slave device that records predetermined data, and a predetermined process that is performed based on the data recorded by the slave device. It has a main unit,
An object of the present invention is to provide a data recording device in which a slave unit and a master unit are each equipped with a clock, in which the clock on the slave unit side is automatically calibrated.

[Embodiment of the Invention] FIG. 1 is a blog IA showing an embodiment of the present invention.

The shared pass 10 is a general shared pass, but this shared pass 10 is equipped with a data recording device 20 and a passenger sensor 21a.
, 21b, 22a, and 22b are provided. Also,
The data recording machine 20 is equipped with a memory pack 30 that stores recorded data and has one clock.

This memory pack 30 is also called a memory cartridge, and includes a battery bar and a backed-up IC memory.

The data recording device 20 records data such as the number of passengers getting on and off, and the passenger sensors 21a to 22b are composed of optical sensors, infrared sensors, and the like. Note that the passenger sensors 21a to 22b may be linked with a numbered ticket issuing machine when detecting the East Shrine, and other sensors (for example, a pressure seat switch) may be used to detect the number of passengers getting off.

In addition, data recording 620 is performed by j! lli! A name announcement button 25 and a route start button 26 are provided. The route start button 26 is pressed when the memory pack 30 is attached to the data recording machine 20, and by pressing it, data for one city day is cleared. Note that instead of providing the route start button 26, it may be configured to clear the previous day's data when the power is turned on.

The master machine installed at the head office etc. performs predetermined processing such as aggregation based on the data recorded by the T-machine.
It is composed of a data reader 40, a computer 41, and a printer 42.

The data reader 40 calibrates the clock on the memory pack 30 side based on the time displayed by the clock on the base unit side when the predetermined data is transferred to the memory pack 30 . Calibration of the clock on the slave device side is performed either immediately before, during, or immediately after data is transferred from the slave device to the parent device.

Next, the operation of the above embodiment will be explained.

FIG. 2 is a flowchart showing the operation of the above embodiment.

Before operating the shared pass 10, first install the memory pack 30.
Attach it to the data recording machine 20, and press the route start button 26.
Turn on (S l). Then, at the starting station, the announcement button 25 is turned on (S2). At this time, the memory address in the memory pack 30 is counted and amplified (33), a delimiter signal is generated, and one clock data is stored (S5).

At this time, data is input from the sensors 21a to 22b to the memory (S6), and the data is written to the memory (S7). Then, when arriving at the next station, the user presses the announcement button 25, stores the data from the sensors 21a to 22b at that station in the memory, and repeats these operations until the terminal station (S8).

When the pass 10 is stored, the memory pack 30 is extracted from the data recording machine 20 (S9), the memory pack 30 is attached to the data reader 40 installed at the head office (or office), and the recorded data is read (S9). 10).

When reading this data, the memory pack 30 (slave unit)
The data of the built-in clock is calibrated (Sll)
. Then prepare for the first day's operation or the next operation.

FIG. 3 is a diagram showing an example of a data table output by the printer in the above embodiment.

In the data table, rlNJ, rOUT'', rTOTA
LJ is the number of passengers boarding the train, the number of passengers getting off the train, and the number of passengers leaving the station, respectively. Although only two lines are shown in this example, data is actually collected for a large number of lines. Furthermore, the display in the above table can be changed arbitrarily. Furthermore, the departure time from each station is compared with its scheduled time, and the delay situation can also be grasped.

In the slave unit, since the driver does not set the time (J!! setting), there is no need to provide a display means such as an LED for displaying the time. Additionally, there is no longer a need for a button for setting the time, which was previously operated by the driver. Further, the clock installed in the slave unit does not need to be an extremely accurate clock, as long as the error within one day (or during one operation) is within an allowable value.

Therefore, the cost of the higher-level slave device is reduced.

In the above embodiment, the slave device is composed of two members: the data recording device 20 and the memory pack 30.
The data collector 20 and the memory pack 30 may be configured as one unit, and this unit may be configured as a slave unit.

[Effects of the Invention] According to the present invention, there is provided a slave unit that records predetermined data and a master unit that performs prescribed processing based on the data recorded by the slave unit, and the slave unit and the master unit each have a clock. In a data recording device equipped with a data recording device, the clock on the handset side is automatically calibrated.
