Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a selection system composed of 11 units and a plurality of slave units, and relates to a selection system including 9 slave units, for example, which is attached to a parts storage box storing inventory parts. The device is used as a component selection device that instructs the extraction of desired components using a master device.

(Prior art) Conventionally, in parts bins that store inventory parts, a large number of parts are stored in parts boxes, etc. at predetermined positions with markings, and the necessary parts are taken out from the parts box and placed there. The remaining quantity was managed by recording the amount taken out on a slip, etc.

(Problems to be Solved by the Invention) However, such a parts container has the following problems.

■ The parts box must be returned to its original position.

Especially if many parts are taken out at the same time, they may be returned to different parts boxes. Also, if you put something back in the wrong parts box, it will take a lot of time to find it.

■ Even if you return one cylinder to its original position, it will be difficult to remember the exact position if there are many cylinders, so it will take time to find the necessary parts unless you are a skilled worker.

■ When taking out different types of parts from many parts boxes at once, it is easy for parts to be dropped. Also.

It is uncertain whether the parts were actually taken or not, so the only way to know is to make a note, for example, on a memo attached to the parts box.゛■ When writing the name of the removed parts on the slip.

Filling errors may occur.

■ Even if the entire parts management is done by the host computer, there are many mistakes because instructions such as taking out two parts cannot be given directly to the parts box.

■ It is difficult to determine the appropriate installation position for a single part because the time from when a part is requested to be taken out to when it is taken out cannot be accurately determined.

(Means for Solving the Problems) The present invention includes a base unit and a plurality of slave units that are mutually distinguished by codes, and the base unit includes an operation unit for selecting and operating the slave units, and a plurality of slave units for selecting one of the slave units. and a first communication section that wirelessly communicates the code of the handset.

The slave unit includes a second communication unit that communicates with the first communication unit, a comparison unit that compares the code sent by the first communication unit and the code of the slave unit, and an external display of the comparison result. The present invention relates to a selection system comprising a display unit for selecting a display unit.

In the manufacturing field, for example, slave units are attached to each parts box storing inventory parts, in the office field, for example, they are attached to each file, and in the service field, for example, they are attached to each of two kept liquor bottles. . The display part.

It consists of external identification means such as a light emitting element and a buzzer.

(Function) When a desired slave unit is selected using the operation unit of the base unit, the address number of the slave unit is transmitted from the first communication unit by, for example, digital optical space communication. Each handset is distinguished from other handsets by an address number, and all handsets receive the address number transmitted by the first communication unit through the second communication unit, and the comparison unit determines whether the address number is A comparison is made to see if the address number matches the address number of the slave device, and if they match, the display section displays the address number externally, thereby making it possible to identify the slave device selected by the parent device to other handsets.

(Example) Below, five examples of the present invention will be described with reference to the drawings.

In this example, a slave device is provided in each of the component storage boxes in which inventory components are stored.

FIG. 1 shows a parts container 1 for storing inventory parts.

The parts storage box 1 consists of parts storage boxes 2.2 that separately store multiple types of inventory parts.
Each of 2... is provided with a handset with a built-in automatic response system. The handset is a low power consumption type digital optical space communication device that is powered by a battery and configured by a microcomputer.

The automatic response system is a system that allows a worker to identify a parts storage box designated by the master unit 5, which will be described later, and also transmits a signal corresponding to the operating status of the slave unit and the remaining quantity of parts.

Further, each of the one-component storage boxes 2,2, .

The master unit 5 is a device that performs digital optical space communication with the slave unit to select the slave unit in the parts storage box 2 in which desired parts are stored, and has a display unit consisting of a keyboard 6 as an operation unit and an LCD. 7 and a buzzer 8.

The keyboard 6 is used to input an address number for distinguishing the slave device, and is composed of hexadecimal keys. The display section 7 displays the contents of the keys pressed on the keyboard 6, and also displays the code answered back from the handset. The buzzer 8 is used to assist the content on the display section 7.
For example, it is used to urgently notify an abnormality in a handset.

On the other hand, a host computer 9 that performs data processing is connected to this base unit 5, and this host computer 9 sends an external code to the base unit 5 and instructs it to select a specific slave unit. , collects the serial data sent by the handset, and processes the data into a form that can be used, for example, for inventory management, quality control, labor management, etc.

FIG. 3 shows the hardware configuration of the base unit 5. As shown in FIG.

Digital optical space communication is performed between handsets.

The transmitting side consists of high-output infrared LED II.

The receiving side is composed of a highly sensitive photodiode 12. The serial data received by the photodiode 12 is input to the input/output interface circuit 14 via the filter amplifier 13.

The signal is output onto the data bus according to a command from the arithmetic processing section 16. On the other hand, this input/output interface circuit 14 controls an LED driver circuit 15 that drives the infrared LED II.

In the figure, 17 is a storage unit consisting of ROM and RAM.

18 is a power supply section; 19 is an R3-232C serial interface that interfaces with the host computer 9; In addition, in this two examples.

The processing results processed by the host computer 9 are externally recorded by a printer 20.

Next, the operation procedure of the base unit 5 will be explained along the flowchart shown in FIG. 4.

In step (2), the selection code of the slave unit attached to the parts storage box 2 in which the desired parts are stored is input. This selection code is made up of various control codes in addition to the address number of the slave device.

This selection code is input by the keyboard 6 of the base unit and also by the host computer 9. Decipher the selection code in step ■ and check the LED on the handset.
A command code (one of the control codes mentioned above) that commands the lighting of No. 3 is included.

In step (2), bit Φ of the transmission serial data is turned ON. On the other hand, if the selection code includes a command code that instructs to turn off the LED 3 of the slave unit, the bit
Turn Φ OFF. These steps ■, ■ bitΦ
When the process is completed, the address number and other control codes of the slave device are transmitted in the form of serial data in step (3).

The corresponding slave unit receives such serial data, and after one worker takes out the part, the confirmation switch 4 is turned on.
When turned ON, an answerback signal including its own address number is transmitted to the base unit 5.

The base unit 5 receives this answerback signal at the step knob (2) and determines whether or not the same address number as the address number transmitted in step (2) has been returned.

If they match, the content of the answerback signal is displayed on the display unit 7 in step (2), and it is determined whether this content needs to be transferred to the host computer 9 in step [phase]. If so, the data is transferred to the host computer 9. on the other hand.

If the address number specified in step (2) and the address number answered back do not match, abnormality processing is performed in step (2). To handle this abnormality, either go back to step (9) and send the serial data again, or go back to step (2) and put it into a standby state where it can receive answerback signals from other handsets again (.

Next, the operation of the slave device will be explained along the flowchart shown in FIG.

In step (2), serial data sent from the base unit 5 is received. Next, the confirmation switch 4 of the slave device is set to O.
Check whether it is set to N using step @, and if the confirmation switch is set to ON.

In step 0, the LED 3 is turned off, and in step @, the confirmation flag is turned OFF, and the process returns to step 0. on the other hand.

If the confirmation switch is OF+' in step @, the process moves to step [phase], and it is compared and determined whether the address number transmitted from vAAs2 matches the address number of the child device. If they do not match, the child device in question has not been selected, and the process returns to step 0; if they match, the child device in question has been selected from the parent device 5.

The process moves to steps [phase] to step [phase] shown below.

In step [phase], the serial data sent from the base unit 5 is latched, and in step 0, bitΦ is ON or OFF.
Determine whether it is F. If it is ON, the LED 3 is requested to be lit, so the process moves to step @ and the LED 3 is lit. On the other hand, if bit Φ is OFF in step O, step [phase] is skipped and the process moves to step [phase]. Step [phase] is the step to create an answerback signal.
A battery alarm 21. Pressure sensor to measure the weight of inventory parts 22. Three pieces of information of the confirmation flag 23 indicating the state of the i-certification switch 4 are inputted via the data latch circuit. The data input in step [phase] is converted into serial data in step [phase], and after being transmitted to the base unit 5, the slave unit returns to step (2).

These serial data sent to the master unit 5 are transferred to the host computer 9, and the remaining quantity of the battery status 2 components of the slave unit is calculated and stored. That is, the host computer 9 utilizes the fact that the information from the pressure sensor 22 corresponds to the remaining quantity of parts in stock, and checks the remaining quantity by dividing in advance by a pressure value corresponding to one part.

Note that instead of the pressure sensor 22, ? & By using the level detection sensor, it is possible to accurately determine the amount remaining in the medicine bottle at all times.

Note that the present invention can also be applied to a security/utility system in which the above-described handset is attached to various crime prevention sensors and the security situation is monitored one after another.
