DETAILED DESCRIPTION OF THE INVENTION "Industrial field of application" The present invention relates to a guidance broadcasting device that can be used for, for example, a bus.

"Prior Art" The applicant of the present invention is, for example, "Japanese Patent Application No. 58-52200: Name:
A guidance broadcasting device "Japanese Patent Application No. 62-29174: Name: Destination guidance and in-vehicle guidance broadcasting device" performs AD conversion of a voice signal such as a stop name to convert it into phoneme data, and numbers this phoneme data. A guide broadcasting apparatus has been proposed and is being sold, which is stored in a memory, and an array of numbers representing phoneme data is designated by index data so as to perform in-vehicle guidance broadcasting and destination guidance broadcasting of a bus.

According to the in-vehicle guidance broadcast apparatus proposed earlier, all the phoneme data used for the guidance broadcast is stored in the semiconductor memory, so that the phoneme data can be repeatedly used.
As a result, it is possible to easily broadcast the same stop name for many days or repeatedly broadcast the destination name to the outside of the vehicle, and to obtain a new action and effect which cannot be obtained by the guide broadcasting device using the magnetic tape. To be

[Problems to be Solved by the Invention] In a guide broadcasting apparatus using a semiconductor memory, which has already been put into practical use, for example, a guide broadcast of an advertisement of a store or the like is performed by observing a passage place for each bus route.

The phoneme data used for advertising is provided separately from the main memory,
For example, it is stored in an IC card type auxiliary memory. The auxiliary memory is detachably connected to the guide broadcasting device, and the phoneme data for advertisement stored in the auxiliary memory is read, for example, every time the guide broadcasting at the next stop is completed, so that the broadcasting can be performed.

The content of the advertisement is fixed for a relatively long period of time.
In other words, considering the labor and cost of writing to the auxiliary memory, it is natural that the advertisement period is at least about 3 to 6 months.

However, in reality, there are some contents that we would like to guide temporarily.

In other words, the guidance of the car circuit, the guidance of the department store's entertainment, etc. accompanying the road construction etc. are contents of the nature to be guided in a timely manner.

In the past, it has been too difficult and difficult to realize such a guide broadcasting for a short period of time, which is too time-consuming.

In other words, since the advertisement guide is inserted in the blank portion of the route guide and broadcast, the index data that determines the broadcasting order of the phoneme data does not have to be rewritten at the guide start deadline and the guide end date and time. This is not possible. In addition, when a plurality of advertisements are stored in the auxiliary memory, the deadlines of the advertisements are different, which makes the management of the deadline even more difficult.

An object of the present invention is to provide a guide broadcasting apparatus that can automatically manage a deadline even with a guide content with a deadline.

[Means for Solving the Problem] In the present invention, the date and time corresponding to the guidance start date and the guidance end date are attached to the phoneme data for which guidance broadcasting is performed with a time limit, and the present date and time clocked by the clock means. Compared to
It is configured so that the guide broadcasting is performed only when the time limit is reached.

Therefore, in the present invention, when a plurality of advertisements with different guidance deadlines are broadcast, the guidance broadcasting apparatus refers to the date data attached to the phoneme data for advertisement stored in the auxiliary memory, and the current date and time is within the deadline of the date data. Operates to broadcast only when it is included.

Therefore, even if the index data defining the reading order of the phoneme data is not rewritten, the phoneme data for temporarily guiding the advertisement or the like can be automatically selected and broadcast according to the date and time. Can be managed.

[Embodiment] FIG. 1 shows an embodiment of the present invention. In FIG.
Reference numeral 10 denotes a guide broadcasting device.

The guidance broadcasting device 10 includes, for example, a central processing unit 11 and
A ROM 12 storing a program for operating the central processing unit 11 according to a predetermined order, phoneme data such as stop names and destination names, and index data for guiding and broadcasting these phoneme data according to a desired order. RAM 13, input port 14, output port 15, and phoneme data output from output port 15
It is composed of a DA converter 16 for A-converting and converting it into an audio signal, and a loudspeaker 17 for broadcasting the audio signal output from the DA converter 16 as sound.

A start switch 18 for giving an instruction to start guidance broadcasting to the input port 14 and the central processing unit 11 are set to a desired operation mode. For example, guidance broadcasting mode, index data rewriting mode, phoneme data rewriting mode, etc. are set. The key board 19 used for switching is connected.

Further, an external connector 21 is connected to the bus line 20 connected to the central processing unit 11, and an auxiliary memory 22 such as an IC card is inserted into the external connector 21 and connected to the bus line 20.

The RAM 13 is provided with a phoneme data storage unit 13A and an index data storage unit 13B, and the phoneme data storage unit 13 is provided.
Phoneme data is stored in A, and index data is stored in the index data storage unit 13B.

Phoneme data is, for example, “Tokyo”, “Shinagawa”, “Shibuya”,
Stop names such as "Shinjuku" and "This bus is""is a line"
It is stored as a digital signal obtained by AD-converting a voice signal representing a phrase such as "next" and "is".

A number such as, for example, is assigned to the phoneme data representing each stop name and each word, and the phoneme data can be read from the RAM 13 by designating this number.

The index data is the number assigned to each phoneme data,
Is sequence data for storing the ... In accordance with the desired guide broadcast sequence. That is, the index data for route No. 1 is composed of data in which numbers are stored in the order of ,,, ..., When the start switch 18 is operated once, the numbers are read one by one, and the read index is read. The phoneme data is read out according to the data, and the phoneme data is repeatedly read out at designated rotations and broadcast for guidance, for example, guiding the next stop name or guiding the destination name outside the vehicle.

In the present invention, the guide broadcasting device 10 is provided with the clock means 23. The clock means 23 can be constructed by using a partial area of the RAM 13, for example. The clock means 23 is RA
The clock is calculated using the allocated area of M13, and the date is updated by one day each time the number of clocks reaches a predetermined value, and the date data is output.

On the other hand, in the present invention, the phoneme data of the advertisement or the like written in the auxiliary memory 22 is provided with date data indicating the date to be guided.

As an example, for example, H891106-H891124 (1989 1
The date data corresponding to the period to be guided (such as January 24) is added.

The central processing unit 11 takes in the date data output by the clock means 23 and holds the current date as data.

A read command for an advertisement or the like stored in the auxiliary memory 22 is read from the index data, and the phoneme data with time limit written in the auxiliary memory 22 is read according to the read command.

The central processing unit 11 refers to the date data fetched from the clock means 23 and the date data added to the phoneme data read from the auxiliary memory 22, and the date data added to the time-limited phoneme data includes the current date. If there is, the read phoneme data with the time limit is sent out from the DA converter 16 and is output as sound.

When the current date and time is out of the range of the date data attached to the time-limited phoneme data, the central processing unit 11 prohibits sending the time-limited phoneme data to the DA converter 16 and does not perform the guide broadcasting.

[Effect of the Invention] As described above, according to the present invention, date data for designating a deadline for guidance broadcasting is added to time-limited phoneme data for which guidance broadcasting is carried out only for a short period of time like an advertisement. If it is within the range including the current date, it can be automatically broadcast, and if the current date is outside the specified range of the set date, the broadcast can be stopped, so advertisements with different dates in the auxiliary memory 22 Even if you have written, the guide will be automatically broadcast within the specified date.

Therefore, it is not necessary to rewrite the index data at each start and end of the due date, and for example, the contents of the auxiliary memory 22 may be rewritten at a cycle of about 3 months for updating the advertisement, and therefore, even for an advertisement that only guides for a short time Instead, the advantage of being able to broadcast the guide is obtained.
