It is. The monitored device 1, the monitoring device 3, and the personal computer 5 are generally installed on the same site. The monitoring device 3 can monitor not only one monitored device 1 but also a plurality of monitored devices. The monitoring device 3 is connected to a telephone 9, a pager 11, and a personal computer 13 via a public line 7. The pager 11 is carried by a remote operator, and when the monitoring device 3 notifies the occurrence of an abnormal situation, the pager 11 sounds and the occurrence of the abnormal situation is notified. The operator makes a key input from the telephone 9,
Notify that "can be dispatched". The personal computer 13 is used when changing various setting conditions in the monitoring device 3 from a remote place. FIG. 2 is a block diagram showing the configuration of the monitoring device 3. The monitoring device 3 includes a processor memory 21, a program ROM 23, a modem 25, a serial port 27, an external input / output terminal 29, and a digital input interface unit 3.
1, a digital output interface section 33, an analog input interface section 35, a tone signal receiving section 37, power supply sections 39 and 41, and batteries 43 and 45. Various setting conditions are stored in the memory of the processor memory 21. The modem 25 is connected to the public line 7 and performs modulation and demodulation of a signal. The personal computer 5 is connected to the serial port 27. Digital information sent from the monitored device 1 is input to the digital input interface unit 31. The digital output interface unit 33 outputs digital information used for remote control to the monitored device 1. The analog input interface unit 35 receives analog information sent from the monitored device 1. The tone signal receiving section 37 transmits the password, ID,
Converts tone signals such as commands into codes
Notify the memory 21. In the monitoring device 3, when an abnormality occurs in the monitored device 1, the occurrence of the abnormality is input as digital information to the digital input interface unit 31 of the monitoring device 3 and transmitted to the operator via the modem 25. . For example, when a gas leak occurs, digital information indicating that a gas leak has occurred is transmitted from the monitored device 1 to the monitoring device 3. When a power failure occurs, digital information indicating that a power failure has occurred is transmitted from the monitored device 1 to the monitoring device 3. In addition, analog information such as the temperature of the monitored device 1 is input to the analog input interface unit 35 when a gas leak occurs. The setting conditions stored in the processor memory 21 include a dial system, a call number, an ID number, a report pattern setting table, an analog information setting table,
There are a source number, number of times of missed acceptance, acceptance waiting time, acceptance password, number of incoming rings, redial interval, number of redials, dial waiting time, announcement waiting time, carrier detection time, transmission level, date and time, operation history, and the like. Here, a call number and an analog information setting table will be described. FIG. 3 shows a table for storing call numbers. The call number is the number of the pager to be reported, and stores the pager number corresponding to the ID as shown in FIG. FIG. 4 shows the analog information setting table. The analog information setting table includes a trigger 51, a message 53, a content 55, a scale 57, and a decimal point position 59. The message 53 is a code for displaying the name of the analog information on the pager 11. That is,
This is a code for displaying temperature and the like. Scale 57
Is the value displayed when 5 volts is input, and the lower limit of scale 57 is the value displayed when 1 volt is input. When an appropriate value (volt) is input, the volt value is changed according to this scale. Decimal point position 59 designates the decimal point position when data is displayed in four digits, and when "0", there is no decimal point, and "1"
, There is a decimal point between the first and second digits from the bottom,
"2" indicates that there is a decimal point between the second and third digits from the bottom. The reason why the scale and the decimal point position are appropriately changed is that the monitoring device 3 is used for not only a single type of monitored device but also various types of monitored devices. Next, the procedure for changing the setting conditions from a remote place will be described with reference to the flowchart of FIG. First, the monitoring device 3 is called from the remote PC 13 (step 501), and a password is entered (step 50).
