The test switch 2 is composed of, for example, a tact switch provided in the main body of the residence building receiver 1, and the test start unit 3, the wiring state determination unit 4, and the abnormality identification unit 5 are the main controls of the residence building receiver 1. The microcomputer 6 which is a part is provided. For example, when the test switch 2 is turned on, the test start unit 3 sends a test start signal to the house information board 11 in each dwelling unit via the data transmission path 21, and a response from the house information board 11 to the test start signal. When the signal is input, the wiring state determination unit 4 determines whether or not the wiring L between the house information panel 11 and the alarm indicator lamp 17 of the door phone 18 is abnormal (disconnection, short circuit) from the response signal. As will be described later, when the identification signal constituting the response signal is at a low level, it is determined that the wiring L is normal, and when the identification signal constituting the response signal is at a high level, the wiring L is disconnected or short-circuited. Accordingly, the abnormality identification unit 5 displays the information of the transmission source attached to the response signal, for example, the address of the house information board 11 on the display unit 7 including a liquid crystal display.
[0011]
The test start signal is composed of, for example, “address of the residence building receiver 1 (address of the transmission source) / test command”, and the response signal is, for example, “address of the housing information board 11 (address of the transmission source) / It consists of “test command command / identification signal”.
[0012]
Next, the house information board 11 which comprises the remote testing apparatus of a door phone is demonstrated. The lighting signal transmission unit 12 and the test response unit 14 described above are provided in the microcomputer 15 that is the main control unit of the house information panel 11. The lighting signal sending unit 12 and the test response unit 14 are each connected to the data transmission path 21, and the lighting signal sending unit 12 is connected to the base of the transistor 16. A constant voltage power supply (12 V) is connected to the emitter side of the transistor 16, and a backflow prevention diode is connected to the collector side of the transistor 16, and is connected to the alarm indicator lamp 17 of the door phone 18 via the wiring L. Has been. The wiring L is connected to an identification signal generator 13 provided on the house information board 11, and the identification signal generator 13 is connected to the test response unit 14.
[0013]
The identification signal generation unit 13 described above has a circuit configuration as shown in FIG. 3 and will be specifically described below.
The negative input side is connected to the collector side of the transistor 16 of the wiring L, the positive input side is connected to the reference voltage (12V), the positive input side is connected to the collector side of the transistor 16 of the wiring L, The negative input side is connected to the reference voltage (12V), the second comparator 13b, the base side is connected to the output side of the first comparator 13a and the second comparator 13b, and the emitter side is set to a constant voltage (5V). A transistor 13c connected to the collector side and connected to the test response unit 14 is provided. For example, when the lighting signal sent from the lighting signal sending unit 12 is sent to the alarm indicator lamp 17 of the door phone 18, the identification signal generator 13 sends the lighting signal to the first and second comparators 13a and 13b. Is detected and compared with a reference voltage, and a signal is output according to the comparison result. When the output signal of one of the first and second comparators 13a and 13b becomes low level, the transistor 13c is turned on and sends a high level identification signal to the test response unit 14 of the microcomputer 15. When the output signals of the first and second comparators 13a and 13b are both at a high level, the transistor 13c is not turned on and a low level identification signal is sent to the test response unit 14 of the microcomputer 15.
[0014]
The first and second comparators 13a and 13b have both output signals at a high level when the alarm indicator lamp 17 is normally lit and when the wiring L with the alarm indicator lamp 17 is disconnected, When the output signal of the first comparator 13a is at the low level, the output signal of the second comparator 13b is at the high level, and the wiring L with the alarm indicator lamp 17 is short-circuited, the first comparator 13a. The output signal of the second comparator 13b is set to a low level.
[0015]
When the test start signal from the wing receiver 1 is input via the data transmission path 21, the microcomputer 15 of the house information board 11 causes the lighting signal sending unit 12 to move the base side of the transistor 16 from the high level at the normal time. When the transistor 16 is turned on at a low level, the lighting signal due to the conduction between the emitter and base of the transistor 16 is sent to the alarm indicator lamp 17 of the door phone 18, and the identification signal from the identification signal generator 13 is input The test response unit 14 attaches to the identification signal information that can identify the transmission source, for example, an address set in the house information panel 11 and sends it to the dwelling receiver 1 as a response signal to the test start signal.
[0016]
The house information panel 11 is connected to a fire detector 11a as shown in FIG. 1, a gas leak detector, a security sensor, an emergency push button, etc. (not shown). In response to this, an alarm is issued from the house information panel 11 or the door phone 18. Then, when the housing receiver 1 detects an abnormality through the housing information board 11 that issued the alarm, the housing ridge receiver 1 issues an alarm or issues an alarm from a speaker (not shown) installed in a common area such as a meeting room. An alarm is issued from an arbitrary housing information board 11 such as the house information board 11 on the same floor or directly above the house information board 11 or the like.
[0017]
Next, the operation of the remote test apparatus of this embodiment will be described.
When the test switch 2 provided in the dwelling receiver 1 is turned on, the test start unit 3 of the microcomputer 6 of the dwelling receiver 1 sends a test start signal to the housing information board 11 of each dwelling unit via the data transmission path 21. The lighting signal sending unit 12 of the microcomputer 15 of the house information board 11 sets the base side of the transistor 16 to the low level to turn on the transistor 16 and sends the lighting signal to the alarm indicator lamp 17 of the door phone 18. At this time, the first and second comparators 13a and 13b of the identification signal generator 13 take in the lighting signals and compare them with the reference voltages.
[0018]
When the alarm indicator light 17 of the door phone 16 is normally lit, the output signals of the first and second comparators 13a and 13b are both at the high level, so that the transistor 13c is turned off and the low level signal is output. The identification signal is sent to the test response unit 14 of the microcomputer 15. The test response unit 14 of the microcomputer 15 attaches a preset address of the home information panel 11 when a low-level identification signal is input, and receives the dwelling receiver via the data transmission path 21 as a response signal. 1 to send.
[0019]
When the wiring L to the alarm indicator lamp 17 is disconnected, the output signal of the first comparator 13a is at the low level and the output signal of the second comparator 13b is at the high level, so that the transistor 13c is turned on. When turned on, a high level identification signal is sent to the test response unit 14 of the microcomputer 15, and when the wiring L with the alarm indicator lamp 17 is short-circuited, the output signal of the first comparator 13a is high level, Since the output signal of the second comparator 13b is at a low level, the transistor 13c is turned on in the same manner as described above, and a high-level identification signal is sent to the test response unit 14 of the microcomputer 15. In this case, the test response unit 14 of the microcomputer 15 attaches the address to the high level identification signal as a response signal and sends it to the dwelling receiver 1 via the data transmission path 21.
[0020]
On the other hand, when the response signal from the housing information panel 11 is input, the microcomputer 6 of the residence building receiver 1 that has sent the test start signal receives the response signal from the housing information panel 11 and the alarm indicator lamp 17 of the door phone 18. It is determined whether or not the wiring L between them is abnormal (disconnection, short circuit). When the identification signal constituting the response signal is at the low level, it is determined that the wiring L is normal. When the identification signal constituting the response signal is at the high level, the wiring L is determined to be disconnected or short-circuited. The source address attached to the response signal is displayed on the display unit 7 to inform the test personnel of the location where the wiring L is abnormal.
[0021]
As described above, in the present embodiment, whether the wiring L between the house information panel 11 and the alarm indicator lamp 17 of the door phone 18 is abnormal (disconnected or short-circuited) is determined from the housing ridge receiver 1 provided in the management room. Since it can be confirmed, it is no longer necessary to go to the location of the doorphone as in the conventional example, which makes it possible to significantly reduce labor and time for wiring confirmation and reduce labor costs. There is an effect.
[0022]
In the embodiment described above, when the wiring between the doorphone 18 and the alarm indicator lamp 17 is confirmed, a test start signal is sent to the housing information panel 11 of all the dwelling units. You may make it confirm and designate the wiring L between the alarm indicator lights 17 of the door phone 18. In this case, after the address of the house information board 11 is displayed on the display unit 7 of the dwelling receiver 1 by a key input (not shown), etc., the test switch 2 is turned on, and a test start signal with the address attached is displayed. The information is sent from the microcomputer 6 and input to the corresponding house information board 11. When the addressed house information board 11 determines that the address attached to the test start signal is its own address, it performs the same operation as in the above embodiment. The test start signal in this case is composed of, for example, “address of the residence building receiver 1 (address of the transmission source), test command command, address of the housing information board 11 (address of the reception destination)”, and the response signal is, for example, It is composed of “address of home information board 11 (address of transmission source), test command command, identification signal”.
When the house information board 11 is specified in this way, for example, after the wiring L with the door phone 18 having an abnormality is redone, the wiring L can be easily confirmed again. Moreover, when a resident | tenant comes to live in an empty dwelling unit, the house information board 11 of the dwelling unit can be specified, and the wiring L between the doorphones 16 can be tested.
[0023]
In the above embodiment, the housing information board 11 immediately sends a response signal to the dwelling receiver 1 when the door phone 18 is remotely tested. When the signal is received, a response signal may be sent to the dwelling receiver 1. Thereby, the response signal from each house information board 11 collides with the data transmission line 21, and the dwelling receiver 1 cannot receive an exact response signal. The test result request signal in this case is composed of, for example, “address of the residence ridge receiver 1 (address of the transmission source), test result request command, address of the housing information board 11 (address of the reception destination)”, and the response signal is For example, it is composed of “the address of the house information board 11 (the address of the transmission source), the test result request command, and the identification signal”.
[0024]
Further, in the above-described embodiment, since the disconnection and the short circuit of the wiring L are the same signal when the transistor 13c is turned on, the transistors are provided, and the disconnection and the short circuit of the wiring L are input to the test response unit 14 as separate signals. Then, the signals may be sent to the dwelling receiver 1 as separate signals, and the dwelling and the short circuit of the wiring L may be displayed separately in the dwelling receiver 1.
[0025]
【The invention's effect】
As described above, according to the present invention, since the wiring between the housing information panel and the alarm indicator light of the doorphone can be confirmed from the housing ridge receiver set at a remote location, This eliminates the need to go to the installation site, which can greatly reduce labor and time for wiring confirmation, and can reduce labor costs.
