FIG. 1 is a block diagram showing an embodiment of a remote monitoring control system according to the present invention.

The remote monitoring control system 1 shown in FIG.
A slave station 2 provided in the vicinity of a road auxiliary facility provided in each part of the expressway, a master station 3 provided in a central monitoring room, and transmission laid between the master station 3 and the slave station 2 The slave station 2 detects the operation state of the road auxiliary equipment and the site-linked equipment 5, processes the detection result, and transmits the processing result to the master station 3 via the transmission line 4. Then, the operation status of the road-related equipment and the site-linked device 5 is displayed on the display panel of the master station 3 or the like.

In this case, the slave station 2 includes an input unit 6, a switching unit 7, a learning unit 8, and a data storage unit 9 as shown in FIG.
, A determination unit 10 and an output unit 11, and when a road incidental facility or the like provided in each section of the expressway has a specific event, a site-linked device 5 that operates in conjunction with the road incidental facility. In addition to capturing the operation state of the above, the operation state is compared with a predetermined specified operation content, and if they match, it is determined to be “good”, and if they do not match, it is determined to be “bad”. After making a decision, the result of this decision is transmitted to the master station 3 via the transmission line 4.

The input unit 6 is an on-site interlocking device 5 which operates in conjunction with ancillary equipment of a highway, for example, tunnel equipment.
Is actually operated, and when the interlocking sequence is collected or when the road incidental equipment has a specific event, for example, a power failure, the operation state of the on-site interlocking device 5 that operates in conjunction with the road incidental equipment is captured. A circuit is provided to supply the operation state of the site-linked device 5 to the switching unit 7.

The switching unit 7 actually operates the on-site interlocking device 5 which operates in conjunction with the road incidental equipment to collect an interlocking sequence (when learning). For example, when a power failure or the like (when monitoring is performed), a circuit that can be switched is provided.
The operation state of the site-linked device 5 output from the input unit 6 is fetched and supplied to the learning unit 8, and when the operation of the site-linked device 5 is actually monitored, the operation state is output from the input unit 6. The operation state of the site-linked device 5 is fetched and supplied to the determination unit 10.

When the learning section 8 learns the interlocking sequence of the on-site interlocking device 5, every time the operating state of the on-site interlocking device 5 is output from the switching section 7, the learning section 8 captures the operation state.
This is statistically processed, and a reference value (reference value) such as an operation state of the site-linked device 5 and a change thereof, that is, an operation content of each site-linked device 5 and an interlock timing of each site-linked device 5, a maximum allowable value A circuit for extracting the reference value, the maximum allowable value, and the like is provided as learning data in a preset format and supplied to the data storage unit 9.

The data storage unit 9 is provided with a memory circuit for taking in learning data output from the learning unit 8 when learning the interlocking sequence of the on-site interlocking device 5 and holding the learning data. The learning data to be output is fetched and held, and when the read command is output from the determination unit 10, the held learning data is supplied to the determination unit 10.

Thus, for example, when the road-related equipment is a tunnel equipment, and this power outage or a tunnel fire occurs, the operation content of the on-site interlocking device 5 that operates in conjunction with the operation, for example, "power receiving CB" is changed to " Time until "off", time until "in-house power generation equipment" becomes "operation",
The time until “power purchase-self-generated circuit switching” becomes “self-generated circuit” is stored in the data storage unit 9 as learning data.

When actually monitoring the operation of the site-linked device 5, the judging unit 10 fetches the operation state of the site-linked device 5 output from the switching unit 7, and stores the operation contents and the data storage unit. 9 is compared with the learning data stored in the storage unit 9. If the operation content of the site-linked device 5 is within an allowable range around the reference value of the learning data,
A circuit is provided for determining "good" and determining "bad" if the value is not within the allowable range.
Feed to 1.

The output unit 11 is provided with a circuit which, when actually monitoring the operation of the site-linked device 5, takes in the judgment result output from the judgment unit 10 and converts it into data in a transmission format. The data in the transmission format obtained by the operation is sent out onto the transmission line 4 and transmitted to the master station 3.

As described above, in this embodiment, the slave station 2 fetches the operation contents obtained when the site-linked device 5 is actually operated, creates learning data, and provides learning data to each section of the expressway. When a road incidental facility or the like is in a specific event state, it is checked whether or not the operation content of the on-site linked device 5 matches the learning data, and whether or not the on-site linked device 5 is operating normally is determined. Since the determination is made and the result of the determination is transmitted to the master station 3 via the transmission line 4, the specified operation content indicating the correct interlocking sequence of the on-site interlocking device 5 can be stored in the slave station 2 side. Accordingly, it is possible to accurately determine whether or not the site-linked device 5 is operating correctly when a specific event occurs, without performing the work of changing the specified operation content on the site side.

In the above-described embodiment, as a learning method, the on-site linked device 5 is actually operated, and the operation content obtained at this time is statistically processed to generate learning data. Based on the design data of the on-site interlocking device 5, the master station 3 calculates learning data, transmits the learning data to the slave station 2 via the transmission line 4, and stores the learning data in the slave station 2 data storage unit 9. May be stored.

By doing so, the learning data of the slave station 2 can be changed even from the master station 3 side, and the versatility can be further improved.

[0027]

As described above, according to the present invention, in the first aspect, it is possible to store the specified operation contents indicating the correct interlocking sequence of the on-site interlocking device in the slave station side. Thus, when a specific event occurs, it is possible to accurately determine whether or not the on-site interlocking device is operating correctly without performing the work of changing the prescribed operation content.
