Description

TECHNICAL FIELD The present invention relates to a supervisory control panel, and more particularly to a supervisory control panel for performing supervisory control of security equipment such as disaster prevention and crime prevention and various lighting equipment in a building such as a building. Is.

[Background Art] Generally, this type of monitoring control board is basically a central processing unit (CPU), an arithmetic processing unit, a transmission control unit connected to a terminal device via a signal line, and a bus for the arithmetic processing unit. A plurality of terminals are provided, and each terminal has a load such as a lighting load, a disaster prevention sensor, a crime prevention sensor, or the like. A sensor is attached. The operation display unit is provided corresponding to each terminal device, and can set the operating state of each terminal device and display the operating state.

By the way, as the operation mode of the operation display unit, for example, an operation mode of the operation display unit is operated, and at the same time, the operation state of the load attached to the corresponding terminal device is changed, or a plurality of operation modes belonging to a predetermined group. There is a group operation mode that changes the operating state of the loads attached to the terminals in the group all at once after operating the operation switches corresponding to the terminals in advance. It was carried out in. In other words, there were some operation modes that were set in advance by the manufacturer and written in the non-volatile memory. However, in this case, the non-volatile operation is required when adding, changing or correcting the operation display section. The memory had to be rewritten, and it was virtually impossible to change the specifications. There is also a setter that separately sets the operation mode, but in that case, since the writable memory is used, the stored contents may change due to the influence of power failure or noise, which is an emergency. Occasionally, a malfunction may occur, causing a problem. Further, it is conceivable that a mode setting switch is used instead of the memory. However, if a mode setting switch is provided on the arithmetic processing unit side, the maximum value of the scale of the operation display unit, that is, the maximum number of connectable terminal units is set. It is necessary to provide a number of mode setting switches corresponding to, and there is a problem that setting is troublesome and an arrangement space becomes large.

[Object of the Invention] The present invention has been made in view of the above points, and its main purpose is to provide an operation display unit with a mode setting switch so that addition, change, correction, etc. An object of the present invention is to provide a supervisory control panel that solves the above problems associated with the specification change and that allows the specification change to be easily performed on site.

Then, as shown in FIG. 1, by inserting the operation display unit 4 from the front surface of the housing 20, the connector 21 is connected to the connector disposed in the housing 20 and connected to the bus 8, and thereby the operation is performed. The display unit 4 is connected to the arithmetic processing unit 1 via the bus 8. The function setting switch 15 is provided, for example, for 8 bits according to the bus 8. The upper 4 bits can set the unique address of the operation display unit 4, and the lower 4 bits can set the mode of the operation display unit 4. ing. The unique address is an address viewed from the arithmetic processing unit 1, and is set individually for each operation display unit 4.
As the mode, for example, the operation switch 11 is operated once, and at the same time, the operation mode in which the load attached to the corresponding terminal unit 3 reverses the on / off operation state, the operation display block 10 is preset, and then the predetermined operation mode is set. There is a group operation mode in which the operating states of the loads 3 attached to the terminals 3 in the group are changed all at once, and these mode settings can be made by the function setting switch 15. The connector 21 and the function setting switch 15 are also provided in units 5 to 7 other than the operation display unit 4, and the units 5 to 7 are calculated by inserting the units 5 to 7 from the front of the housing 20. The unit 1 can be connected to the processing unit 1, and the function setting switch 15 can set the unique address of each unit 5 to 7 and the mode.
