DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

The embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

The embodiments of the present disclosure are described below with specific examples, and other advantages and effects of the present disclosure will be readily apparent to those skilled in the art from the disclosure in the specification. It is to be understood that the described embodiments are merely illustrative of some, and not restrictive, of the embodiments of the disclosure. The disclosure may be embodied or carried out in various other specific embodiments, and various modifications and changes may be made in the details within the description without departing from the spirit of the disclosure. It is to be noted that the features in the following embodiments and examples may be combined with each other without conflict. All other embodiments, which can be derived by a person skilled in the art from the embodiments disclosed herein without making any creative effort, shall fall within the protection scope of the present disclosure.

Example one

The utility model discloses an improvement of doing on the basis of current 8 way bus clutch. A16-path bus linkage device can correspond to linkage information of electronic fence hosts of 16 defense areas, and one bus linkage device is equivalent to 2 8-path bus linkage devices. Compared with 2 8-path bus linkage devices, the device saves one device, is simple and convenient to operate, and controls the cost. The 16-path bus linkage device outputs 16-path switching value alarm signals for linkage between the electronic fence host system and other alarm systems. The 16-path bus linkage device is communicated with a control center by monitoring the electronic fence host, extracts alarm information therein, outputs a corresponding defense area switching value signal, and is widely applied to system schemes for linkage of an electronic fence system and other alarm systems such as monitoring, an LED electronic display screen and an alarm platform.

The utility model discloses a 16 way bus clutch, as shown in fig. 1, including 485 communication unit, MCU unit, electrical unit, reset unit, alarm processing unit and warning output unit. The 485 communication unit receives 485 signals of the peripheral alarm equipment, the output end of the 485 communication unit is connected with the first input end of the MCU unit, and the reset unit is connected with the second input end of the MCU unit. The power circuit supplies power to the MCU unit. The output end of the MCU unit is connected with the input end of the alarm processing unit, the output end of the alarm processing unit is connected with the input end of the alarm output unit, and the alarm output unit outputs 16 paths of switching value signals.

The working principle of the device is shown in figure 2, and the 16-path bus linkage device receives 485 signals uploaded by peripheral alarm equipment through the 485 communication unit, identifies defense area numbers of the device and working parameter information of the device. When the alarm information is received, an alarm processing unit in the bus linkage device processes the alarm information, controls the corresponding IO port to output high level, and opens the corresponding defense area switching value signal. And when the received signal is a reset signal, the MCU controls the corresponding IO port to output a low level, the switching value signal of the corresponding defense area is closed, and if the alarm signal is not received, the MCU does not act.

The 16-path bus linkage device automatically identifies linkage information of the electronic fence host through internal processing, and one-to-one correspondence can be realized without programming. The bus linkage device can output 16 switching value signals, the default labels are 1-16, and the default labels correspond to the defense areas of the electronic fence host respectively (the defense areas of the electronic fence host correspond to the defense areas in a one-to-one correspondence relationship). For example, the fence host 2 can alarm in a defense area, the bus clutch is identified through 485 signals, the bus clutch is processed through the internal MCU, and the output signal controls the second switching value to be output. When the electronic fence host machine 2 is used by a user, the alarm information of the electronic fence host machine 2 defense area is only required to be connected to the No. 2 switching value output terminal of the 16-path bus linkage device.

The reset unit is used for resetting the 16-path bus linkage device product, and all outputs of the 16-path bus linkage device are closed after the reset unit is started. The reset working principle is as shown in fig. 3, a reset key on the product shell is pressed, the reset unit works, a reset signal is output to the MCU, the MCU controls all IO ports to output low level, the relay is opened, and the normally closed and normally open contact is reversed.

Preferably, the 16-way bus linkage device further comprises a signal lamp, when the 16-way bus linkage device is in normal communication with the electronic fence host system, the MCU controls the signal lamp to flash for prompting, and when the communication fails or the system is incompatible, the MCU controls the signal lamp to be on for a long time.

Preferably, an address dial switch is arranged in the 16-path bus linkage device, and more than two 16-path bus linkage device cascade expansion can be performed. When the number of the electronic fence hosts exceeds 16 defense areas, one bus linkage device cannot meet the use requirement, and the bus linkage device needs to be added for capacity expansion. By controlling the dial switch, the default address of 00000 corresponds to the switching value signal output of 1-16 defense areas, and when an address is added, the serial number of the electronic fence host corresponding to the output of the 16-way bus linkage device is correspondingly increased by 16. For example, when the bus is dialed to '0001', the 16-path bus linkage device corresponds to the switching value signal output with the serial number of 17-32 defense areas. For example, the electronic fence host has 18 defense areas, the control center needs to output corresponding 18 switching value signals, namely 2 16 bus linkages are needed, the two bus linkages are output corresponding to the switching value of 1-16 defense areas under the default condition, then, the dial switch of one bus linkage is only required to be dialed to be '0001', and the switching value signal output by the bus linkage represents No. 17-32 defense areas. The capacity expansion can be realized through a simple dial switch, the back-end programming is not needed, and the operation is simple.

Fig. 4 is an illustration of the correspondence of the dip switches to the 16-way bus clutch encoding.

The above description is for illustrative purposes only and is not intended to limit the present invention, and any modifications, equivalent substitutions, improvements, etc. that do not depart from the spirit and principles of the present invention should be construed as within the scope of the present invention.
