PURPOSE:To clarify the input period and input time of a collected data by providing a shift means moving up the storage location of a succeeding data by one period when no data is inputted over one period to eliminate waste of memory. CONSTITUTION:A data collector is provided with a CPU1 controlling the entire system, and a keyboard 2 inputting various operating processing instructions is connected to the CPU1. Further, an ROM3 storing a control program, an RAM4 storing the processing data of the CPU1, a reference signal generating circuit 5 and an alarm informing circuit 6 are connected to the CPU1. The circuit 5 inputs a time data to the CPU1 and when no data input is given over one period, the storage location of the RAM4 for the succeeding data is moved up by one period at the CPU1. When the data counted at the CPU1 and the alarm data of the RAM4 are coincident, the circuit 6 generates an alarm to clarify the input period and input time of collected data. |
