Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a program timer with a printing device.

[Prior Art] Conventionally, some program timers that control a plurality of loads at respective set times are equipped with a printing device that prints the name of the controlled load, the control time, and the program contents.

[Problems that the invention aims to solve] The above-mentioned devices are generally used in schools, factories, etc., and security and disaster prevention management is necessary in such places, but they are completely different from program timers. Management was carried out using a grid management system. Therefore, two systems had to be installed, which was disadvantageous in terms of space and cost.

In addition, a reference clock is also required on the management system side, and the program timer must be synchronized with this clock, which is extremely troublesome.

This invention is advantageous in terms of space and cost.
It provides a program timer with management functions.

[Means for Solving the Problems] The present invention is provided with a control circuit that causes a printing device that prints load control information to print information input from an external information source such as a sensor.

[Embodiment] In FIG. 1, 1 is a clock pulse generator;
Reference numeral 2 denotes a control section consisting of a microcomputer, which has various functions such as a program timer function, a load control function, and a printing control function. 3 is a setting device for setting the control time of the load 4, 5 is a child clock, and 6 is a sensor, for example, for crime prevention and disaster prevention. Reference numeral 7 denotes a printing device that prints the load name, load control time, control information such as control status, program information, sensor name, and time when input information is received from this sensor.

Next, the operation will be explained with reference to the flowcharts of FIGS. 2 and 3. FIG. 2 shows the main operation, and FIG. 3 shows the interrupt operation performed every second. First, the interrupt operation will be explained. When a pulse arrives every second from the clock pulse generator, the slave clock 5 is driven and the time set by the setting device 3 is compared with the current time. If the two match, the output flag is set to 1 and a control output for the corresponding load is generated. When the generation of this output is complete, set the output flag to 0.
and set the output completion flag to 1. When input information is received from the sensor 6, the sensor input flag is set to 1.

Next, the main operation will be explained. First, it is determined whether the output completion flag is 1, and if it is 1, control information is printed. After this printing, the output completion flag is reset. Next, it is determined whether the sensor input flag is 1, and if it is 1,
The input information of the sensor, that is, the sensor name and the time when the input information was received are printed as shown in FIG. After this printing is completed, the sensor input flag is reset.

[Effects of the invention] According to the invention, since information from an external information source such as a sensor is printed using a printing device that prints load control information, a single system can perform load time control, It is possible to provide an inexpensive and multi-functional system that can perform record management for the purposes of crime prevention and disaster prevention. Moreover, since there is only one time reference source, time adjustment etc. can be easily performed.
