And a control signal for controlling the managed device 5 is generated. The CPU 19 performs the management and the calculation of the sales amount based on the managed device selection signal and the component selection signal, and displays the calculation contents on a display device (not shown) as needed.

Reference numeral 39 is a managed device selection signal detection circuit. The managed device selection signal detection circuit 39 responds to the managed device selection signal from each switch sw by inputting the managed device selection signal to the selected input terminal 8. The signal representing the input is input to the CPU 19. Each element selection signal detection circuit 39 of the managed device and the selection input terminal 8 are connected in parallel, and a switching transistor 40 is arranged between both 8 and 39. Each selection input terminal 8 is connected to each collector terminal of the transistor 40, the input terminal of the managed device selection signal detection circuit 39 is connected to the base terminal of each transistor 40, and the emitter terminal of each transistor 40 is grounded. .

Then, the managed device selection signal detection circuit 39 supplies a bias current to the base terminal of each transistor 40 and applies a predetermined voltage between each base terminal and the emitter terminal. Further, the managed device selection signal detection circuit 39 detects the opening / closing of each switch sw by measuring the voltage between the base terminal and the emitter terminal and measuring the change in the voltage between the base terminal and the emitter terminal. The managed device selection signal detection circuit 39 and the CPU 19 may be connected by a serial line.

Next, a case where a wire breakage is detected by the device having the above configuration will be described below.

CPU1 when the managed device selection signal is in the first mode
Reference numeral 9 inputs the open / close signal to the base terminal of the transistor 23, and a managed device selection signal having a voltage smaller than the breakdown voltage of the Zener diode 12 is generated. Therefore, the first
In this mode, normally, that is, when the switches sw1 to sw6 are opened, the selection output terminal 7 and the selection input terminal 8 become non-conductive. Therefore, 5V is applied to the input terminal of the inverter 36 (output terminal of the photocoupler 35),
Since the "H" level is maintained, the output terminal of the inverter 36 becomes the "L" level.

When any one of the contacts a and b of the switches sw1 to 6 is closed, one of the selection output terminals 7 ₁ to ₆ and one of the selection input terminals 8 ₂₁ to _4l are connected to the signal line. Conducted through 11. Then, the current flows from the power supply circuit 21 to the photocoupler 35, the selection output terminal 7, the switch sw, the selection input terminal 8, the transistor 40, and the GND in this order, and the LED of the photocoupler 35 lights up.

As a result, the current flows from the power supply circuit 41 to the photocoupler.
The input terminal of 35, the input terminal, and the GND flow in that order, and the output terminal of the photocoupler 35 becomes 0 (zero) V. For this reason,
Since the input terminal of the inverter 36 changes from "H" level to "L" level, the output terminal of the inverter 36 changes from "L" level to "H" level. As a result, the CPU 19 causes the output terminal of the inverter 36, that is, the component selection signal to be “L”.
Based on the change from the level to the "H" level, the specific selection output terminal 7 to which the closed switch sw of the switches sw1 to 6 is connected is identified. This switch sw
Data representing the selected output terminal 7 connected to is stored in the memory 37 by the CPU 19.

On the other hand, the managed device selection signal detection circuit 39 increases the voltage applied between the base terminal and the emitter terminal of the transistor 40 connected to the specific switch sw in response to the closing of the specific switch sw. Based on the increase of this voltage, each switch sw
A managed device selection signal representing the managed device 5 provided with the closed switch sw out of 1 to 6 is input. Therefore, the managed device selection signal detection circuit 39 can identify a specific managed device selection signal among the plurality of types of selection signals and can input the managed device selection signal to the CPU 19.

Then, the host computer 6, that is, the CPU 19 identifies the specific component selection signal stored in the memory 37 and the specific managed device selection signal from the managed device selection signal detection circuit 39. The management device 5 and the specific switch sw of each element are selected and an operation for generating the control signal is performed. Then, the calculation contents are displayed on the display device as needed.

Next, when the managed device selection signal is in the second mode, the CPU 19 inputs the opening / closing signal to the base terminal of the transistor 23 to generate a selection signal having a voltage (10 V) higher than the breakdown voltage of the Zener diode 12. To do. Therefore, in the second mode, between the selection output terminal 7 and the selection input terminal 8, the Zener diode 12 (or switch
It is always on by sw1 to 6). Therefore, the LEDs of all the photocouplers 35 are turned on, and the output terminals of all the inverters 36 are always at the "H" level. Therefore, the CPU 19 inputs (selects) all component selection signals.
It will be in the state of being. Similarly, the managed device selection signal detection circuit 39 enters a state in which all managed device selection signals are input. Therefore, the CPU 19 detects (identifies) that all the signal lines 11 are conducting.

Therefore, when the specific signal line 11 is disconnected in the second mode, the output terminal of the specific inverter 36, to which the signal line 11 and the selected output terminal 7 are connected, changes from "H" level to "L" level. . That is, the specific component selection signal is input in negative logic. In other words, the disconnection of the signal line 11 generates a component selection signal. Then, the CPU 19 can identify the signal line 11 to which the specific switch sw is connected based on the change of the output terminal of the inverter 36 from the "H" level to the "L" level. The CPU 19 stores in the memory 37 data representing the signal line 11 relating to this specific component selection signal.

On the other hand, the managed device selection signal detection circuit 39 is a specific signal line.
In response to the disconnection of the signal line 11, the voltage applied between the base terminal and the emitter terminal of the transistor 40 via the specific selection input terminal 8 to which the signal line 11 is connected decreases.
Based on the decrease in this voltage, the managed device selection signal detection circuit 39 detects the signal line to which the specific selection input terminal 8 is connected.
Identify 11. In other words, the managed device selection signal is generated due to the disconnection of the signal line 11. This allows
The managed device selection signal detection circuit 39 can input to the CPU 19 a managed device selection signal indicating a particular signal line 11 which is broken among the signal lines 11 connected to the selection input terminal 8.

Therefore, the CPU 19 connects the signal line 11 disconnected from all the signal lines 11 based on the data related to the component selection signal stored in the memory 37 and the specific managed device selection signal. The specific managed device 5 and the specific switch sw can be identified and detected. Then, the identification detection content is displayed on the display device as needed.

In this embodiment, the input of the selection signal to the CPU 19 or the managed device selection signal detection circuit 39 by closing the switches sw1 to sw6 is invalid when the selection signal is in the second mode, that is, a specific 30 ms period. Is applied. However, it is possible to detect the disconnection of the signal line 11 after a lapse of 130 ms at the longest, and this input invalid section has no practical problem. Also, switches sw1 to 6
In addition, it is easy to validate the input in the invalid section by providing a monostable pulse generating circuit, a memory, or the like (not shown). Further, when the monostable pulse generating circuit is provided in the present apparatus 1, the generated pulse width is the time during which the selection signal is in the second mode (in the case of this embodiment,
Longer than 30 ms) (see Fig. 5).

Further, the present invention can be easily incorporated into the management device 1 currently used. In that case, the managed device 5
The Zener diode 12 is connected in parallel to each of the switches sw provided in, and the program for the host computer 6 to execute is provided with the first mode and the second mode. Since the Zener diode 12 has a polarity, it is necessary to check the polarity of the Zener diode 12 with a measuring device such as a tester when connecting the switch sw in parallel. When the work of checking the polarity is shortened or when the above measuring instrument is not possessed, the same polarities of the two Zener diodes 12 are connected as shown in FIG. 6 and FIG. , The two Zener diodes 12 connected in this way constitute a Zener diode connection body.), The element of the apparently non-polar Zener diode 12 is switched.
Just connect to sw in parallel.

(Effect of the invention) According to the invention described in the first aspect of the invention, it is possible to detect the disconnection of a specific signal line and the selection output terminal and the selection input terminal to which the disconnected signal line is connected. be able to. Therefore, it is possible to quickly and easily find a signal line connection failure, such as forgetting to connect, and immediately correct the signal line connection failure, so that data exchange between the managed device and the host computer can be performed accurately. Be seen. Therefore, it is possible to prevent illegal acts such as intentionally disabling data exchange between the two by operating the sales of the hall by the host computer, managing the managed device, and operating the connection point between the host computers. it can.

Further, in order to detect the disconnection of the specific signal line, it is sufficient to make a slight improvement to the management device currently used, and a new device is not required. For this reason, workability and economical efficiency during the improvement work are extremely excellent.

In addition, since the first mode and the second mode are selected alternately, the above-described function of distinguishing between the selected output terminal and the selected input terminal in the first mode and the above-described disconnection detection function in the second mode are performed. It is possible to achieve it alternately.

According to the invention as set forth in claim 2, the Zener diode connection body composed of two Zener diodes having the same poles connected to each other is apparently in a non-polar state. Since the Zener diode is polarized, when one Zener diode is connected in parallel to the switch, it is necessary to check the polarity, which makes it necessary to prepare a polarity check measuring device and to provide a polarity check work process. . On the other hand, by connecting the above-mentioned Zener diode connection body in parallel with the switch, a polarity check measuring device is not required, and the polarity check work process is abolished to improve the assemblability and eventually the productivity. Can be planned.
