[0024] Example 1

[0025] like Figure 1 As shown, the present invention includes a mobile phone remote terminal, a cloud server, a LORA gateway, a fence control system handheld terminal, an infrared radio counter and a snap-on fence connection alarm. The infrared radio counter is connected to the LORA gateway via the RS485 protocol, the snap-on fence connection alarm is connected to the LORA gateway via LORA wireless, the fence control system handheld terminal is connected to the LORA gateway via WIFI data, the LORA gateway uploads all received data to the cloud server via 4G, and the mobile phone remote terminal can use 4G to view specific data for monitoring through the cloud server.

[0026] To ensure the interconnection between various devices, the LORA gateway integrates the LORA wireless of the fence connection alarm, the RS485 of the infrared counter-radiation counting device at the fence entrance and exit, the WIFI of the handheld terminal, and the 4G that transmits data to the server.

[0027] The fence control system handheld terminal is installed with server and client software;

[0028] In order to accurately count the number of people entering and leaving the channel, the infrared beam counter adopts mature infrared photoelectric fuzzy recognition technology and the application of infrared detection principles. It distinguishes and judges whether someone passes through according to the fuzzy recognition algorithm, and uses DSP timing measurement technology to judge the direction of human body passing to complete the accurate counting of people entering and leaving the channel; at the same time, the system equipment terminal is not affected by light and shadow, nor is it affected by the swing of people's arms during walking; the entry and exit directions are counted separately, and the entry and exit directions can be freely set; the system can monitor the time, number, and average daily stay time of people entering and leaving in real time.

[0029] The entire system uses on-site handheld terminals or mobile phone APPs to monitor the number of people working on-site, alarm status, etc. in real time, so that you can have a clear understanding of the on-site operation situation and control safety in real time;

[0030] If a worker opens the fence connection without permission and enters the live area, a real-time sound and light alarm will be sounded and the fence disconnection number will be prompted to improve timeliness;

[0031] The three-axis acceleration sensor can be used to classify strong vibration, tilt, and dumping of the guardrail, and prompt it on the handheld terminal to accurately perceive the status;

[0032] The system can query alarm information and entry and exit information in historical operations, which is convenient for historical operation analysis and subsequent tracking; it also supports real-time review of online operation alarm information and alarm records.

The battery 87 is installed inside the bottom of the connector body 81. A switch 88 and a buzzer 89 are provided at the bottom of the connector body 81. A processor 810 is also installed inside the connector body 81. The snap lock 82 is U-shaped and passes through the two sets of locks 84. A snap 83 is provided on the snap lock 82 and is used in conjunction with the limit switch 86.

[0036] The snap-on fence connection alarm supports 48 fence connection alarms to be connected simultaneously.

[0037] Connect multiple groups of snap-on fence connection alarms together through fence connectors 8. When a guardrail is disconnected, moved, strongly vibrated, tilted, etc., the three-axis acceleration sensor 4 senses the specific situation, and then the signal is uploaded to the cloud server to send data information through wireless technologies such as LORA and 4G. The handheld terminal and sound and light alarm 7 can be used on site to prompt that someone has broken in or the guardrail is disconnected, dumped, tilted, etc., and the situation can be displayed remotely through a mobile phone APP;

[0038] The whole system is powered by rechargeable lithium batteries or solar energy. The lithium battery power supply time is more than 48 hours, which meets the maintenance work requirements.

[0039] The fence connector 8 connects multiple groups of snap-on fence connection alarms together by using a snap lock 82, and the electromagnetic lock 85 fixes it, and then the travel switch 86 cooperates with the snap 83 to switch the fence connector 8;

[0040] During normal deployment, if the fence connector 8 is disconnected, the buzzer 89 will be used to prompt the staff to quickly find the disconnection point.
