Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a portable data collector that collects data, and particularly aims to reduce the capacity of a built-in battery and reduce the weight of the shed.

In a vending machine data collection system using this type of portable data collector, for example, three
Sales data such as the number of products sold, the amount put in, and the amount paid out is stored in the storage units built into each of the vending machines 1, 3, and 3, and is attached to a portable data collector t on the car panel. A cable S having a plug at the tip is connected to, for example, a vending machine AT, a power switch t is turned on, and a data collection start signal is transmitted by key operation on the keyboard 7, and data is stored in a storage unit built into the vending machine L. By sequentially performing similar operations on the vending machines λ and 3, the respective stored data is collected and stored in the data collector ψ.

When the collection of sales data from each vending machine +@/, 2, and J is completed as described above, the data collector is connected to a central *m device (not shown) to transfer the collected data. , various data are aggregated and processed using the central processing equipment. Further, 1 is a printer that collects data from the vending machines /, J, and J and prints out the data as needed, and 9 is a display that displays input from the keyboard 7, data, etc.

Generally, as shown in the block diagram shown in Figure 1,
The portable data collector has a tip as shown in Figure 1.
A cable with a plug that allows connection to a vending machine 1 A power switch 6 that supplies and cuts off power, A keyboard 7 that controls the exchange of various data, A printer 11 that collects data and prints it as needed. It is equipped with a display 9 that displays the information, and also has an entire portable data collector q inside.

A controller 10 to which a cable j is connected and a memo IJ-// which temporarily stores collected data.
, a clock circuit /J that transmits time signals for sending and receiving various data to the memory l/, and a battery 13 as a built-in power supply that supplies power to each component. Regarding the power supply to these components, in a conventional portable data collector, as shown in Fig.
The battery 13 is directly connected to the battery 13 and the battery 13 is used to supply power at all times, and the other components 7 to 10 only need to be supplied with power when transmitting and receiving data.
tm.

A switch 6 is provided, and the power switch 6 is closed only when data is exchanged to prevent battery 13 from being exhausted.

Such conventional power supply systems have the following drawbacks.

(1) If you forget to open the power switch B at the end of data transfer, the battery 13 will be wasted unnecessarily.

(3) Since the battery 13 supplies power to components with high power consumption, such as the printer 11 and the display 9, the battery 13
There is a need to increase the capacity of the battery 13 or replace the battery 13 frequently.

It is an object of the present invention to eliminate the above-mentioned conventional drawbacks, and to directly connect only the components that require constant power supply, namely the memory and the clock circuit, to the battery so that they are always supplied with power from the battery. The object of the present invention is to provide a portable data collector that is small and lightweight by preventing consumption and reducing the required capacity as much as possible to reduce the battery storage space.

Another object of the present invention is to simplify key operations on a keyboard by automatically starting data transfer when power is supplied to the controller.

In other words, the portable data collector of the present invention is a portable data collector that connects to a vending machine to collect sales data, and the built-in battery supplies power to circuits that require constant power supply, while also supplying power to other circuits. is characterized in that power is supplied from the vending machine by connecting it to the vending machine during data collection.

The present invention will be explained below with reference to the drawings.

An embodiment of the portable data collector of the present invention is shown in block diagram form in FIG. As is clear from comparing the illustrated configuration example with the conventional configuration shown in FIG. 2, the power supply system for the memory/1 and clock circuit 12 is the same as in the conventional configuration.
The power supply system for the other components 7 to 10 is different from the conventional example.

That is, the built-in battery 13 is directly connected to the memory l/and clock circuit 12 to constantly supply power to these components, and other components are connected to the second circuit.
Everything including the power switch 6 in the figure has been removed to minimize the power consumption of the built-in battery 13. on the other hand,
The other components 7 to 10 are connected to the automatic light absorption machine or the central management device via a cable j that connects to the vending machine or the central management device and exchanges data with the controller 10 as before. Power is supplied only when cable S is connected. The controller 10 is configured to detect the rise of the start of power supply from the external power source and start data exchange, thereby simplifying the operation by eliminating the need for the conventional key operation on the board 7 to instruct the start of data exchange. It will be planned.

The portable data collector of the present invention constructed as described above operates as follows.

That is, when connecting to a vending machine and collecting sales data, the controller 10. Electric power is supplied to the printer, etc., and sales data is led to the controller 10 and further stored in the memory //. When the data collection is completed and the cable S is disconnected from the vending machine, the power that had been supplied from the vending machine is cut off, and the controller 101, printer 11, display 9, and keyboard 7 are all disconnected. Although the operation is stopped, the memory // and the clock circuit 12 connected to the battery 13 continue to operate, and the data stored in the memory // is maintained as is. Note that the controller 10 detects the rise of the power supply voltage supplied from the vending machine and uses it as a data collection start signal, reads data from the vending machine and stores it in the memory //, and also reads data from the clock circuit /J. Read out the time and store it//
is memorized. In addition, the printer 1 prints data read from the vending machine as necessary, and the keyboard 7 is used to create and input data such as the date, or to input the corrected time of the clock. The display 9 displays these input data according to the input data supplied from the keyboard 7, and the clock circuit 1
Display the time data from 2.

As is clear from the above description, according to the present invention, in a portable data collector used in a vending machine, components that consume a large amount of power or require particularly low voltage are Power is supplied to these two components from the connected external device, and the built-in battery is used only for components that require constant power supply, so the required capacity of the built-in battery can be minimized or its lifespan can be reduced. Not only can this eliminate the need for a power switch, it also eliminates wasteful consumption of the built-in battery due to forgetting to turn off the power switch. Furthermore, since the capacity of the built-in battery is reduced, the battery storage space can be reduced and the overall size and weight can be reduced. Furthermore, since data collection is started by detecting the rise of the externally supplied power supply voltage, a portable data collector with excellent operability such as simplified keyboard operations can be obtained.
