Definitions

  • This invention relates to a disaster prevention system or equipment which includes a plurality of terminal units or devices such as fire detectors (sensors) or the like and a receiver to which the plurality of terminal devices are connected and which includes storage means for previously registering the terminal devices destined to be connected to the receiver to perform the supervision and control of the terminal devices.
  • a disaster prevention system or equipment which includes a plurality of terminal units or devices such as fire detectors (sensors) or the like and a receiver to which the plurality of terminal devices are connected and which includes storage means for previously registering the terminal devices destined to be connected to the receiver to perform the supervision and control of the terminal devices.
  • a plurality of terminal devices such as fire detectors are connected directly to a receiver or connected by way of a repeater station to the receiver, wherein monitoring and various controls are performed by the receiver or the repeater.
  • the receiver or the repeater is provided with storage means for registering therein the terminal devices to be connected. More specifically, the terminal devices to be connected are previously registered in the storage means, wherein the various monitoring and controlling operations are carried out on the basis of the registered information.
  • Japanese Patent Application Laid-Open No.65398/1985 discloses a system for providing fire alarm equipment capable of transmitting the classification information of the detectors to a receiver without influencing the signal bit numbers of the detected information, based on temporarily separating the transmission of the classifying information from that of the detected information, where a terminal device basically responds to the request for the classification information as issued by the receiver by sending back the information corresponding to one of different levels prescribed for the type of detector, respectively, so that the receiver can identify the type or classification of detector. After identifying the detector type, a request for transmission of the detected information is issued by the receiver, which can then determine if there has been an outbreak of fire from the received detection information on the basis of the result of the decision previously performed concerning the type of detector. In either case, if the terminal device is connected erroneously, this fact can not be recognized by the receiver. In other words, the receiver makes decisions based on the perception that the interconnections are correct.
  • GB-A-2 149 547 discloses a disaster prevention system comprising a receiver to which various terminal units are connected by a transmission trunk. Therein the receiver comprises storage means for storing the addresses of the terminal units, and the terminal units comprise storage means for their self addresses. In case of coincidence of address and self address during a polling operation, the terminal unit in question is energized.
  • an object of the present invention is to provide a disaster prevention system which is capable of recognizing the non-connected state of units or devices as well as erroneous connections of units or devices of different types and automatically putting aside the unit or device of concern from a set of objects to be monitored and controlled while informing an operator of this fact through print out or other means to thereby allow error in the settings as well as erroneous connections to be readily detected, without continuous occupation of the display window, to thereby facilitate countermeasures as required.
  • a disaster preventing system comprising a receiver or repeater and a plurality of terminal devices connected thereto and monitored and/or controlled by the receiver or repeater by way of a transmission trunk
  • the receiver or repeater comprises display means for indicating monitored and/or control information of the terminal devices, and first storage means in which the addresses of the terminal devices to he connected to the receiver or repeater are registered
  • the terminal devices each comprise a first memory for storing a self-address for collating the same with address signals received from the receiver or repeater during a polling operation, and in case of a coincidence of address and self-address, for responding to a request for monitored information and/or delivering a control output
  • the terminal devices comprise second memories for storing a classification code of the terminal device to be sent to the receiver or repeater

  • the repeater T1 includes a CPU, a read-only memory ROM11 for storing programs and a work random access memory RAM11 and additionally a second switch S2 for setting the address or call number of this repeater station T1, and a third switch S3 for setting the classification (type) of this repeater T1 or a classification setting read-only memory ROM12 and so forth, wherein the set classification code or the status information of a fire detector FD is sent back to the reciver R in response to the call number and the call classification as issued by the receiver R.
  • the read-only memory ROM2 is loaded with the numbers (addresses) of the terminals scheduled to be connected or operated as well as classification or types (smoke sensor, heat sensor, gas sensor, sensor repeater, smoke preventing/expelling repeater or the like) as the information inherent to the individual terminals at the time of shipping from the factory.
  • classification or types smoke sensor, heat sensor, gas sensor, sensor repeater, smoke preventing/expelling repeater or the like
  • the classification codes collected from the individual terminals are checked as to whether they coincidence with the data stored in the read-only memory ROM2, wherein the number and the classification code of the terminal for which the abovermentioned coincidence is found are registered as the inherent information in the random access memory RAM2 so that the contents stored therein can be made use of in the course of operation.
  • Fig. 2 illustrates in a flow chart in more detail the above outlined operation to be performed by the receiver R according to this invention.
  • the receiver R performs a calling or polling operation to the repeaters in sequential order starting from the repeater station allocated with a first address to the repeater of the last address.
  • a block 101 zero (0) is set for the address n , being followed by a block 102 where the receiver R issues a request for the classification code for the n-th repeater, whereupon a timer TM is activated at a block 103.
  • the abovementioned classification code as received is stored in a register A (not shown) (at block 105) while the classification code of the n-th repeater stored in the ROM2 is read out to be loaded in a register B (also not shown) (at block 106), being followed by comparison of the contents of both of these registers (at block 107).
  • the classification code and the address code of the n-th terminal device or the repeater are registered in the RAM2 at n-th memory location (at block 108).
  • the ordinary monitoring/controlling operation of the disaster prevention system is started with the recognition that only the terminal devices registered in the RAM2 through the procedure described above are normally operating terminal devices.
  • Fig.3 illustrates in a flow chart the operation to be carried out in each of the repeaters.
  • the terminal Upon calling from the receiver R (YES at block 201), the terminal collates the address as received with its own address (block 202). When coincidence is found (YES at block 203), then decision is made as to whether the classification code is requested. If the classification code is requested (YES at block 204), the classification code set at the switch S3 or in the read-only memory ROM12 is sent back to the receiver (block 205). After sending-back the classification code, the operation returns to the beginning to await the arrival of the next call signal. Upon arrival of the next call signal, the sequence starting from block 201 is repeated.
  • test circuit is driven (block 211). After driving the test circuit, the operation returns to the beginning to await the arrival of the next call signal. Upon arrival of the next call signal, the sequence starting from block 201 is repeated.
