Definitions

• the present invention relates to a device for time-dependent control of a system with machines and / or devices, which has a master clock electronics with clock lines emanating from it and devices connected to the latter, which are operatively connected to the machines or devices.
• Control devices of the type mentioned which are also known as clock systems, have been state of the art for a long time and are used for the pre-programmed switching on and off of light sources, machines or bones, for triggering acoustic or optical signals and for controlling work processes , Machine functions and the like are used.
• the programs of these control devices are permanently installed in them and their use is limited to relatively rigidly defined requirements.
• the object of the invention is to create a device of the type mentioned at the outset, in which, with relatively little additional effort, the device can be adapted to changing requirements over time and thus an expansion of its field of application.
• a device for solving this problem is characterized in that the master clock electronics are designed to accommodate interchangeable program modules.
• various programs can be inserted into the master clock electronics one after the other with very simple measures and certain program changes can be carried out for the desired time periods to apply. Any number of such modules can be available, which gives the device extensive adaptability and a greatly expanded range of application gives.

• FIG. 2 shows the mechanical arrangement of the device according to FIG. 1
• the master clock electronics has a counter functioning as a master clock 1, which is preceded by a device 2 which displays the normal time and which emits this as a signal.
• the master clock 1 is followed by a pulse generator 3 and a computer 4 'serving as a control element 4.
• the computer 4 ' is followed by a driver 5 for a number of relays 6, the outputs of which are not shown in the drawing and external devices and machines are connected.
• the computer 4 ' is also followed by a data encoder 7 and this is followed by a device containing the line control 8 and the driver 9 for the clock lines 10, 11. This is also electrically connected to the pulse generator 3.
• the master clock electronics also contains a power supply unit 13 with emergency power supply and a program module 14 connected to the computer 4 '.

• Relay 22 connected, which controls the external machine and device not shown in the drawing.
• the program module 14 visible in FIG. 2 has a read memory 23 which is a program for the temporal Control of the entire system contains. Slave clocks, time clocks, time calculators, time printers, time indicators, etc. can be controlled; Furthermore, external devices and machines can be switched on and off and controlled 5 depending on the time.
• the program module 14 can be inserted into the computer 4 'and can be pulled out to change the program and easily replaced by another module which contains a program corresponding to the new requirements 0.
• the modules can be stored and transported without restriction. Programming is preferably carried out by the manufacturer or his representative. Therefore, no special technical knowledge is required from the customer. In the event of a program change, he only has to replace the modules sent to him. Old programs can be kept for possible reuse.
• FIG. 2 The mechanical design of the control device is shown in FIG. 2. On a base plate 24 is in
• a mounting plate 25 which carries the line control 8 and the electrical connections 26.
• a pivot frame 27 which is pivotable relative to the base plate 24 serves as a housing for the 5 master clock electronics, not shown in this figure.
• the program module 14 with the read memory 23 can be pushed into the swivel frame 27, in its open position, and inserted into the computer 4 'of the master clock electronics. Such an arrangement has proven to be practical, simple and economical.
• the master clock electronics are designed in such a way that bipolar minute and / or second pulses and coded serial pulses for data transmission can be generated on the clock lines 10, 11.
• control device can be integrated in the master clock electronics.
• be pluggable which alternately control the system according to periodically changing requirements.
• the number of controllable machines and devices is practically unlimited and only requires a corresponding program and additional control devices to be connected to the clock lines of the machines and devices to be controlled.
