BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to a remote control device for a mobile engine, and more particularly to a remote control device for supplying signals to a mobile engine by wire.

0002

2. Description of the Related Art In a conventional remote control device for a mobile engine of this type, as shown in FIG. 6 and the required number of moving rollers 61, 61,...
were constructed, and the signal transmission cable 7 was fixed to these moving rollers 61 at appropriate intervals. Then, the tip of this cable 7 is connected to the auxiliary control section of the mobile engine 2.
2, signals from the main control section M are transmitted to this auxiliary control section 22, thereby controlling the operating section 21 of the mobile engine 2. When the mobile engine 2 moves, the cable 7 moves along with the mobile engine 2 by appropriately widening or narrowing the interval between the moving rollers 61, 61, . . . due to its traction force.

By the way, in such a conventional remote control device for a mobile engine, by appropriately widening or narrowing the interval between the moving rollers 61, 61, . . .
Since the tips of the cables 7 were moved, these cables 7 were repeatedly bent and stretched between the moving rollers 61, 61, . It has the disadvantage that it takes time and effort to manage.

[0004] In order to solve this drawback, the inventor installed a trolley wire along the traveling direction of the mobile engine, and installed a trolley member (pantograph) on the mobile engine.
A remote control device for supplying a signal to a mobile engine by bringing this trolley member into contact with the trolley wire has been devised and applied for (Japanese Patent Application No. 3-13838).

[0005]

[Problems to be Solved by the Invention] However, in the remote control device for a mobile engine of the prior application, a contact pattern between the trolley member and the trolley wire was used to send a signal to the mobile engine, so that Sparks occur between the trolley member and the trolley wire during travel, and as a result, the auxiliary control section receives an abnormal signal, which may make it difficult to properly control the mobile engine in accordance with the control signal.

[0006] An object of the present invention is to eliminate such inconveniences.

[0007]

[Means for Solving the Problems] In order to achieve the above object, in the remote control device for a mobile engine according to the present invention, an auxiliary control section is installed in the mobile engine, and a contact method between the trolley wire and the trolley member is used. In a remote control device for a mobile engine that controls the operation of the mobile engine by transmitting a signal from a main control unit to an auxiliary control unit of the mobile engine, the auxiliary control unit stores the normal signal when it receives the normal signal. At the same time, the operation of the mobile engine is controlled based on this normal signal, and when an abnormal signal is received, the operation of the mobile engine is controlled based on the stored signal.

[0008]

[Operation] Since the remote control device for a mobile engine according to the present invention is configured as described above, even if the auxiliary control section of the mobile engine receives an abnormal signal, the mobile engine can be controlled by this abnormal signal. There isn't.

Therefore, if this remote control device for a mobile engine is used, sparks will occur between the trolley member and the trolley wire while the mobile engine is running, and as a result, even if the auxiliary control unit receives an abnormal signal, , the mobile engine is normally controlled according to the control signal.

[Example] As an example of the mobile engine according to the present invention,
A cast product transport vehicle used in the casting process will be described below based on the drawings.

In FIG. 1, reference numeral 1 denotes a traveling rail, and 2 denotes a casting transport vehicle placed on the traveling rail 1 (corresponding to the "mobile engine" of the present invention). The conveyance vehicle 2 has a power section 21 and an auxiliary control section 22, and operates the power section 21 based on instructions from the auxiliary control section 22 to move on the running rail 1 in the direction of the arrow, or move the cast object (see Fig. (not shown) to grasp or release. 3 is a set of trolley wires, which is installed above the rail 1. As shown in FIG. 2, this trolley wire group 3 is composed of three power supply trolley wires (bare wires) 31, 31, 31 and two signal transmission trolley wires (bare wires) 32, 32. has been done. Note that 33 is a trolley wire cover, which covers the trolley wire group 3. This trolley wire cover 3
3 has a C-shaped cross section as shown in FIG. Next, 41
is a board of the trolley member 4, and is installed inside the trolley wire cover 33. This board 41 is a roller 411
, 411 in the horizontal direction (in FIG. 1). Terminals 42 and 43 are installed on the surface of the substrate 41. 42 of these terminals are in contact with three power supply trolley wires 31, 31, 31, respectively. Further, the terminals 43 are in contact with two signal transmission trolley wires 32, 32, respectively. Therefore, the trolley member 4 can move in the direction of the arrow within the cover 33 while contacting the terminals 42, 43 with the trolley wires 31, 32. Reference numeral 5 denotes a group of connecting lines, which are fixed to the transport vehicle 2. This connection line group 5 is composed of three power connection lines 51 and two signal connection lines 52.
One end is connected to the terminal 42 and the other end is connected to the power section (of the transport vehicle 2) 21, one end of the signal connecting line 52 is connected to the terminal 43, and the other end is connected to the control section 22. connected to the target. Therefore, power is supplied to the power section (of the conveyance vehicle 2) 21 from the power supply trolley wires 31, 31, 31 via the connection line group 5, and the signal transmission trolley wire 32,
Signals such as operation start and stop are supplied from the main control section M to the auxiliary control section (of the transport vehicle 2) 22 via the main control section 32.

Next, the operation of the auxiliary control section 22 will be explained based on the flowchart of FIG.

(1). Receives signals from main control unit M.

(2). It is determined whether the received signal is a normal signal.

[0015]■. If it is abnormal, the next signal will be received.

[0016]■. If normal, the signal is stored.

(3). The operating section 21 of the transport vehicle 2 is controlled based on this stored signal.

(4). Receive the next signal from the main control unit M.

(5). It is determined whether the received signal is a normal signal.

[0020]■. If it is normal, the signal is stored in place of the already stored signal, and the operating section 21 of the transport vehicle 2 is controlled based on this stored signal. After control, the next signal is received.

[0021]■. If there is an abnormality, the operating section 21 of the transport vehicle 2 is controlled based on the already stored signal. After control, the next signal is received.

[0022]

Effects of the Invention In the remote control device for a mobile engine according to the present invention, an auxiliary control unit is installed in the mobile engine, and a signal from the main control unit is transmitted to the auxiliary control unit of the mobile engine using a contact method between a trolley wire and a trolley member. A remote control device for a mobile engine that controls the operation of the mobile engine by transmitting information to the mobile engine,

When the auxiliary control section receives a normal signal, it stores the normal signal and controls the operation of the mobile engine based on the normal signal, and when it receives an abnormal signal, it controls the operation of the mobile engine based on the stored signal. Since the operation of the mobile engine is controlled, even if the auxiliary control section of the mobile engine receives an abnormal signal, the mobile engine will not be controlled by this abnormal signal.

Therefore, if this remote control device for a mobile engine is used, sparks will occur between the trolley member and the trolley wire while the mobile engine is running, and as a result, even if the auxiliary control unit receives an abnormal signal, , the mobile engine is normally controlled according to the control signal.
