Abstract

PROBLEM TO BE SOLVED: To process sequentially information with higher priority by discriminating the priority of text information sent from a plurality of slave stations. SOLUTION: Slave stations 11a-11n use a monitor controller such as air- conditioner and lighting provided in tunnels scattered on a highway to send text information to corresponding transmission modules M0-Mn. Reception text information notice sections 12a-12n provided to the transmission modules M0-Mn inform the received text information to a reception information management section 14 via a system bus 13. The reception information management section 14 is provided with a management table, which stores information of priority discriminated by the reception text information notice sections 12a-12n as a cross reference table with respect to a transmission module index. For example, high priority is placed on a fault of an air-conditioner in a tunnel. The reception information management section 14 references the management table to send the text received by the transmission module with highest priority to a host module with high priority.

In the information transmission processing system having such a configuration, text information having priority is now transmitted from the slave stations 11a to 11n to the respective transmission modules M0 to Mn.

For example, if an abnormality occurs in one of the tunnels scattered on an expressway in terms of air conditioning, the abnormality information is naturally greater than the information of other tunnels having no abnormality. The priority is high, and if this high-priority abnormality information occurs in the slave station 11a, the abnormality information is sent to the transmission module M0 corresponding to the slave station 11a. The priority of the text information received in the transmission module M0 is determined, and the information of the determination result is sent to the reception information management unit 14 via the reception information notification unit 12a,
The received information management unit 14 manages the priority of the text information received by the transmission module M0. Then, the text information received by the transmission module M0 having the highest priority is sent to the upper module 15 with the highest priority, and the received text is processed therein. For example, the processing of the text information in the tunnel in which the abnormality has occurred is performed. Will be given top priority.

FIG. 2 is a block diagram showing another embodiment of the information transmission processing system of the present invention. The same components as those in FIG.

In the system shown in FIG. 2, a reception information control unit 16 is added to the system shown in FIG. The reception information control unit 16 is provided between the reception information management unit 14 and the upper module 15, and controls the priority of the text information using a management table as shown in FIG. This figure is shown according to the information of FIG. According to FIG. 5, for example, the transmission modules M1 and M2 for priority 3 are determined as having the same priority in this management table, and it is not determined which one has the highest priority.

Next, the operation of the information transmission processing system shown in FIG. 2 will be described with reference to the management table shown in FIG. In this system, the received text information notification units 12a to 12n included in each of the transmission modules M0 to Mn include the slave stations 1a to 1n.

In the system having such a priority judging unit 17, the same priority 3 is sent from the current child stations 1b and 1c.
The text information of FIG. 5 is transmitted by the transmission modules M1 and M2.
Suppose they were sent to each. In this case, the reception information control unit 16 continues to determine the text information of the same priority managed by the reception information management unit 15 as the text information of the same priority (FIG. 5). Therefore, the priority determination unit 17 determines which of the text information having the same priority has the highest priority only for the text information having the same priority, based on the registration table of FIG. In this case, according to the registration table (FIG. 6), the priority of the text information received by the transmission module M2 is 5, while the priority of the text information received by the transmission module M1 is 2. Therefore, the transmission module M2 is selected as the highest priority transmission module.

Here, the fact that "the transmission module M2 has the highest priority" is transmitted to the reception information control unit 16, and upon receiving this, the reception information control unit 6 gives the highest priority, for example, a text corresponding to the transmission module M2. Information is transferred to upper module 1
5 is transmitted.

That is, the upper module 15 can quickly know the transmission module M2 to be processed with the highest priority from the information controlled by the reception information controller 16.
