Description

[Detailed Description of the Invention] Technical Field C] The present invention relates to a simple simulator for a disaster prevention system, and is used in place of an uninstalled repeater, especially when a repeater is added to a disaster prevention receiver. be.

[Background technology]

The receiver 1 is connected to repeaters ml, m2, . m2...mn
The key point is a disaster prevention system that systematically controls the system by interlocking the loads L1 to Ln connected to each repeater ml, m2...mn by performing multiplex transmission signal processing using a polling method between the repeaters. Although it has been developed as an address system (see Figure 4), malfunctions in such disaster prevention systems can cause serious unforeseen damage to human life and other property, so operation tests and program debugging after system construction are completed are not recommended. It has become an essential element.

When building a disaster prevention system, normally,
The reality is that due to delays in delivery and installation work, it is not possible to connect all the repeaters required by the system to the receiver at once, so repeaters are installed in several parts. Often.

Considering these circumstances, in order to improve efficiency during system start-up, it is necessary to be able to perform operational tests of the disaster prevention system and debug programs even during the system construction stage.

[Purpose of the invention]

An object of the present invention is to provide a simple simulator that makes it possible to test the operation of a disaster prevention system and to debug programs even when the disaster prevention system is in the middle of construction or will be expanded in the future.

[Disclosure of the Invention] A simple simulator of the present invention proposed to achieve the above object includes a signal conversion circuit that processes multiplexed signals sent from the receiver side, address data extracted from the signal conversion circuit, and An address check circuit that determines whether the address data matches the address data stored in the address map memory, a control data processing circuit that processes the control data taken out from the signal conversion circuit in response to the match signal from this address check circuit, and this control circuit. An address data/control data output circuit that receives an output signal from the data processing circuit and displays and outputs address data and control data, and a reply data process that receives a match signal from the address check circuit and outputs reply data to the signal conversion circuit. It is characterized in that the address map memory automatically stores address data corresponding to uninstalled repeaters among the multiplexed signals sent from the receiver.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a schematic configuration of an internal circuit of a simple simulator of the present invention. The N-Chang simulator 2 is connected to the existing multiplex signal 'llA1 and connected to the receiver l.

Reference numeral 10 denotes a signal conversion circuit that converts a multiplexed signal sent from a receiver (not shown) into a formant suitable for the internal circuit of the simulator, and converts a signal with a formant suitable for the internal circuit into a multiplexed signal.

11 is address mump memory, 12 is signal conversion circuit 1
an address check circuit that compares the address data retrieved by the address map memory 11 with the address data stored in the address map memory 11; 13 is a timing signal generation circuit provided to synchronize the operation timing of the internal circuit;
14 is a control data processing circuit that processes the control data taken out from the multiplex signal conversion circuit 10; 15 is an address/control data output circuit 516 that displays and outputs the determined address data and the control data; is an address check circuit 12; The figure shows a reply data processing circuit that outputs reply data corresponding to the address when it receives a match signal from the address. Note that the internal circuit of the simulator 2 also includes a CPU for reading control signals output to the multiplex signal line 1, but these are not shown in this figure.

FIG. 2 is an explanatory diagram of a usage example of a simple simulator,
mlxmn indicates an already installed repeater, 1 indicates a receiver, 2 indicates a simulator provided in place of an uninstalled repeater, and 1 indicates a multiplex signal line.

The receiver 1 sends out a multiplexed signal in the formant shown in FIG. 3(a) in a so-called time sharing method according to the designed program of the disaster prevention system.

This multiplexed signal is sent to each repeater m1 by the so-called polling method.
~ mn and receiving the signal from the receiver 1, each repeater mlxmn determines that the address code set for itself matches, and drives the loads L1 to Ln connected to each in accordance with the control signal, Reply data is sent back from the repeaters m1 to mn (see FIG. 3(b)), and is decoded on the receiver 1 side.

In this kind of polling process, the first process is
In the existing repeaters m1 to mn, when it is determined that the address data match, the loads L1 to Ln connected to each are driven according to the control signal, and in the receiver 1, the signals are sent from each of the repeaters m1 to mn. Although the reply data is received, the reply data cannot be received for the signals sent to the uninstalled repeaters m I J ~ mm'. This state is caused by the receiver l and simulator 2. The address data determined by both parties and corresponding to the signal for which there is no reply data is stored in the address map memory 11 of the simulator 2. In this way, the address codes of the uninstalled repeaters ml' to mm' to which no reply data could be returned are set in the simulator 2, and the simulator 2 serves as a substitute for the uninstalled repeaters.

In the second and subsequent polling processes, when the address data stored in the address map memory 11 of the simulator 2 is sent from the receiver 8!1, the address check circuit 12 checks whether the address data match. If the address data match, the control data processing circuit 1
4 is activated to decode the control data, and the address/control data output circuit 15 obtains address data and a quasi-arc output indicating the contents of the control data. At the same time, the address
Since the reply data processing circuit 16 also becomes active due to the defeat signal, the reply data is sent to the receiver 1 side via the signal conversion circuit 10.

On the other hand, when the addresses of the multiplexed signals sent from the receiver l match, the existing repeaters m1 to mn operate the loads L1 to Ln connected to each one, and at the same time send back reply data to the receiver l.

In this way, with the present invention, it is possible to conduct actual system operation tests for existing repeaters, and for uninstalled repeaters, it is possible to obtain a reconnaissance output according to the content of the control data, thereby improving the disaster prevention system. In addition to making it possible to perform systematic tests on systems, it also makes it easier to decode the program of the designed system.

〔Effect of the invention〕

As can be understood from the above explanation, according to the simple simulator of the present invention, when a disaster prevention system is in the middle of construction, or when it will be expanded in the future, it can be used simply by connecting to the existing multiplex signal line. It is extremely convenient because the address code corresponding to the installed repeater can be stored and used as a substitute for the uninstalled repeater.
