MONITORING SYSTEM |
摘要 |
<p>Monitoring System The monitoring system comprises a control device (16) operated by a battery (30). A monitoring circuit (31) is provided for the control of the battery voltage. Upon the connection or disconnection of the enabling switch (20), the detection circuit (24) produces a pulse by which the switch (37) of the monitoring circuit is caused to be conductive. The time of the battery check is restricted to the duration of said pulse. Thus, a permanent discharge of the battery (30) is excluded by the monitoring circuit. (Fig. 1).</p> |
