The intelligent fire alarm detector P includes: a base 1, a detection unit 2, a detection element 3 and a power source 4. Among them:

The base 1 is provided with a negative terminal 11, and the negative terminal 11 is formed by spaced apart two elastic sheets 12 in a normally-off state. In addition, the base 1 is provided with a positive pole 13.

The detection unit 2 is combined with the base 1. A negative conductive sheet 21 is provided inside the detection unit 2 at a position corresponding to the negative terminal 11, and a positive conductive sheet 22 is provided at a position corresponding to the positive terminal 13. After the detection unit 2 is combined with the base 1 and fixed, the negative conductive sheet 21 can just press the two elastic sheets 12 to make contact and conduction, so as to pass a current. After the detection unit 2 is separated from the base 1, the negative conductive sheet 21 no longer presses the two elastic sheets 12 of the negative terminal 11, and the two elastic sheets 12 return to a normally-off state. The positive conductive sheet 22 can contact and conduct the positive terminal 13 for the current to pass. In addition, the detection unit 2 is provided with a signal terminal 23. The detection unit 2 can be selected from detectors with different detection functions, which are combined with the base 1 to detect the effects of generating heat, temperature, or smoke.

The detection element 3 is arranged on the base 1. As shown in the third figure, the detection element 3 is provided with a first detection terminal 31, a second detection terminal 32 and a ground terminal 33. The first detection terminal 31 is signally connected to the positive terminal 13 to detect a change in a voltage value or a current value of the current passing through the positive terminal 13. The second detection terminal 32 is signal-connected to the signal terminal 23 of the detection unit 2 to detect that the current passes through the signal The change of the voltage value or the current value of the signal terminal 23. The ground terminal 33 is signally connected to one of the elastic sheets 12 of the negative terminal 11, so that after the two elastic sheets 12 are in contact and conduction, the voltage value or the change in the current value of the current passing through the negative terminal 11 is detected. When the detection element 3 detects that the voltage value is not equal to (including higher or lower than) a voltage standard value, or the current value is not equal to (including higher or lower than) a current standard value, it will correspondingly emit An alarm signal. The abnormal signal can be transmitted to a remote server C via a wireless router A and an Internet service provider (ISP) B via an Internet B1 (as shown in Figure 4). In addition, the detection element 3 is provided with a test switch 34 and a restart switch 35. The test switch 34 is electrically connected to the detection unit 2 for manually forcing the detection unit 2 to trigger, thereby simulating the triggering state after detecting a fire phenomenon such as heat source, temperature or smoke, or whether the circuit is tested abnormal. The restart switch 35 allows the detection element 3 to reconnect with the wireless router A for transmission. The detection element 3 is a single chip microprocessor.

The power source 4 is set on the base 1. The power source 4 is electrically connected to the detection unit 2 and the detection element 3 to provide backup power in the event of a power failure.

During installation and use, as shown in Figures 4 and 5, a plurality of the intelligent fire alarm detectors P are electrically connected to a switchboard D, so that the intelligent fire alarm detectors P are connected in parallel to form a circuit D1 , And make the current pass through the loop D1. And install these smart fire alarm detectors P to different areas, floors or rooms. Each user who enters a handheld electronic device E can download an application program (APP), which can communicate with the remote device through the wireless router A and the Internet service provider B through the Internet B1. The server C stays connected for receiving the alarm signal at any time.

The voltage of the current supplied by the switchboard D to each of the smart fire alarm detectors P is 24V or close to 24V. Furthermore, a 10KΩ terminal resistor D2 is welded between the base 1, the negative terminal 11 and the positive terminal 13, which is the farthest from the trusted switchboard D. The high resistance of the terminal resistor D2 makes the current flow in the loop D1 Can be reduced to an extremely low level.

When the smart fire alarm detectors P do not detect heat, temperature, or smoke and other fire field phenomena, and are in a normal state, at this time, the detection element 3 detects the current passing through the loop D1 The change in the voltage value or the current value. If the detected voltage value falls within the standard voltage value (for example, between 16 volts and 18 volts), there will be no trigger. Or the detected current value falls within the current standard value, and there will be no triggering either.

If any one of the detection units 2 is damaged or separated from the base 1 abnormally, so that the negative conductive sheet 21 no longer presses the two elastic sheets 12 to make contact and conduction, the two elastic sheets 12 will return to normal disconnection. State, make the circuit D1 open (as shown in the sixth figure). At this time, when the detection element 3 detects that the voltage value of the current passing through the loop D1 is 0 volts or the current value is 0 amperes, it is not equal to the voltage standard value or the current standard value. If it is detected by the detection element 3 of the smart fire detector P on the slave side, an abnormal signal will be sent to the smart fire detector P on the master side, and then the smart fire detector P on the master side will detect the abnormality. The signal is transmitted to the remote server C through the wireless router A and the Internet service provider B through the Internet B1. The server C can learn from the abnormal signals sent by the different detection elements 3 which one of the smart fire alarm detectors P is faulty or abnormal, so that it can be checked and repaired immediately.

When any one of the detection units 2 detects a fire phenomenon such as heat source, temperature or smoke, the detection unit 2 will be triggered (as shown in the seventh figure). At this time, the detection element 3 detects that the voltage value of the current passing through the loop D1 is not equal to the voltage standard value, or detects that the current of the current is not equal to the current standard value. The detection element 3 will send out an alarm signal, which is then transmitted to the remote server C through the wireless router A and the Internet service provider B through the Internet B1. The server C can learn from the alarm signals sent by the different detection elements 3, which one of the smart fire alarm detectors P has detected a fire phenomenon such as heat source, temperature, or smoke, and immediately report it Fire-fighting unit and go to extinguish fire or rescue. At the same time, the server C uses the wireless router A and the Internet service provider B The alarm signal is transmitted to the user's handheld electronic device E (such as a smart phone or a computer) located at the alarm location through the Internet B1, so as to notify and guide the user to leave quickly and safely.

When detecting the smart fire alarm detectors, as shown in the first and fourth figures, the test switch 34 can be directly triggered to manually force the detection unit 2 to trigger, thereby simulating the detection. After a fire phenomenon such as heat source, temperature or smoke is generated, the detection element 3 is made to detect a change in the voltage value or the current value passing through the loop D1, or whether the test circuit is abnormal, to test whether the entire system is operating normally middle. By triggering the restart switch 35, the detection element 3 and the wireless router A can be reconnected for transmission.

In this way, as shown in the fifth figure, the present creation system can detect the voltage value or the change of the current value of the current passing through the loop D1 through the detection element 3, and you can immediately know whether the alarm detector detects Normally, whether the detection unit 2 and the base 1 are damaged or separated, and other abnormalities such as heat source, temperature or smoke can be detected, and the alarm will be issued immediately and the location of the alarm will be notified to facilitate the user immediately escape.

This creation can also be a base device of an intelligent fire detector. As shown in the first and third figures, the base device includes the base 1 and the detection element 3 described above. A single base device formed by combining the detection element 3 and the base 1 can be used in conjunction with a detection unit 2 that detects heat, temperature, or smoke, etc., and can improve its versatility and universality . In addition, the overall wiring line is simplified, installation and maintenance are easy, and the cost can be greatly reduced.

The detection method of the intelligent fire detector created in this invention is implemented in conjunction with the above-mentioned intelligent fire detector P. As shown in the first and fifth figures, the current is passed through the loop D1 of the smart fire alarm detector P, and the built-in detection element 3 is used to detect the voltage value or the change in the current value of the current. It is detected that the voltage value is not equal to the voltage standard value, or the current value is not equal to the current standard Value, the smart fire detector will correspondingly send out the alarm signal, and if the voltage value is 0 volt or the current value is 0 ampere, the smart fire detector will correspondingly send out the abnormal signal.

The voltage standard value is after the smart fire alarm detector P is actually installed in a field. After measuring the volt value of a safe working voltage of the circuit, the current standard value is also after the field installation, after measuring the circuit A safe working current ampere value. And the safe working voltage volt value or the safe working current ampere value obtained by the measurement in the loop is written into the detection element 3 (single chip microprocessor) to provide the voltage value or the current value Compare. Therefore, in actual use, it will be detected that the voltage value is not equal to the safe working voltage volt value, or the current value is not equal to the safe working current ampere value, and the alarm signal is correspondingly issued.
