[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] The utility model relates to a cable type temperature sensing detector interface box, which is mainly used for connecting the cable type temperature sensing detector. When the cable type temperature sensing detector is used, the connection is realized through the interface box.

[0019] Specifically, it includes a box body, in which a microprocessor is arranged. Here, the microprocessor model is HA2089-I / SL.

[0020] Several terminal interfaces are arranged on the surface of the box for connecting components. The terminal interfaces on the interface box include terminal interfaces for connecting the bus, ports for connecting the temperature detector and power ports. Different terminal interfaces have different functions.

[0021] In a specific implementation, three groups of ports for connecting the temperature detectors are provided in the terminal interface, and each group has two ports. Further, the specific temperature detector is a cable-type temperature detector, and a terminal resistor is connected to the end of the cable-type temperature detector.

[0022] like Figure 1 As shown, the interface box can connect three groups of cable-type temperature detectors. Terminals 13 and 14 form a group, terminals 11 and 12 form a group, and terminals 9 and 10 form a group. They are connected to the two wires of the cable-type temperature detectors respectively, regardless of polarity. The end of the temperature cable should be connected to the terminal resistor with a resistance of 20K. Terminals 7 and 8 are connected to DC110V, where terminal 7 is connected to the positive and terminal 8 is connected to the negative. Terminals 1, 2, 5 and 6 are connected to the two buses of the controller respectively, where terminals 1 and 5 are connected to one bus, and terminals 2 and 6 are connected to the other bus, regardless of polarity. Terminals 3 and 4 are grounded.

[0023] The interface box is provided with several dip switches on the surface of the box body, and the address can be set by the dip switches. Specifically, 6 dip switches are provided, and the address is set by the cooperation of the 6 dip switches. The address is set by the dip switch, and the address code of H9969 is set by the dip switch. The method is binary weighted method. The switch is turned to the ON side, indicating that this bit is 1, and the switch is turned to the digital side, indicating that this bit is 0. For example: the address number is 21, the setting method of the dip switch is as follows: Figure 2 shown.

[0024] The utility model arranges mounting holes on the bottom plate of the box body, and then uses screws to mount the box body on the wall through the mounting holes.

[0025] The utility model can be used to receive the alarm and fault signals of the cable-type temperature sensing detector, and transmit the processing results or intermediate data to the alarm controller. The utility model has strong anti-interference measures, can ensure no missed alarms, and reduce false alarms.
