[0037] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0038] In order to realize multi-point monitoring of the real-time status of the rangefinder, the utility model proposes a status signal monitoring system for the rangefinder, comprising:

[0039] A signal collector electrically connected to the rangefinder, used to collect DC voltage state signals corresponding to various operating states of the rangefinder, and process the signals into Ethernet data packets and then send them to the local area network;

[0040] The operating status of the rangefinder includes: normal status, standby status and shutdown status;

[0041] Normal status: indicates that the rangefinder is operating normally, all system parameters are within the preset range, and the device functions well;

[0042] Standby status: This usually means that the rangefinder is in standby status, perhaps as a backup option in the event of a failure of the primary device, or as a replacement device used during scheduled maintenance;

[0043] Power off status: It means the rangefinder is not running, which may be due to maintenance, failure, energy saving needs or manual shutdown.

[0044] The signal collector comprises: a first control board circuit, such as Figure 6 The interface board circuit shown and the first serial port server;

[0045] The interface board circuit is used to collect the DC voltage state signal corresponding to each operating state of the rangefinder, and convert it into a DC level signal of a preset amplitude (5V) and transmit it to the first control board circuit;

[0046] It should be noted that Figure 6 In the interface board circuit shown in FIG. 1 , this embodiment actually uses only three input ports (such as (1+, 1-), (2+, 2-) (4+, 4-)), and the three input ports are respectively connected to the 24V DC voltage state signals corresponding to the normal state, the standby state and the shutdown state, and the output ports also use only three (such as the corresponding O1, O2, O4), and the three output ports are connected to the state signal input port (such as Figure 3 The IN connection in FIG. 1 is shown in FIG. 1 (the IN includes 6 terminals, but only 3 terminals are used in this embodiment).

[0047] The first control board circuit is used to process the 5V DC level signal into an RS232 serial port signal and send it to the first serial port server;

[0048] The first control board circuit includes: Figure 1 The first single chip circuit shown in Figure 2 The first serial port circuit shown and the interface board circuit are electrically connected to the interface board circuit. Figure 3 The status signal input port shown;

[0049] The state signal input port is used to connect the DC level signal of a preset amplitude in the interface board circuit to the first single-chip microcomputer circuit;

[0050] The first single-chip microcomputer circuit is used to encode a DC level signal of a preset amplitude into an RS232 serial port signal, and send it to the first serial port server through the first serial port circuit.

[0051] The first serial port server is used to convert RS232 serial port signals into Ethernet data packets and send the Ethernet data packets to the local area network.

[0052] The first control board circuit also includes:

[0053] like Figure 5 The first power conversion module shown is used to access the 220V AC voltage and convert it into a DC voltage of a preset amplitude (24V), and input the DC voltage of the preset amplitude into the first control board circuit, the interface board circuit and the first serial port server.

[0054] One or more status displays; the status display includes a plurality of indicator lights showing different colors; the indicator lights correspond one to one with the operating status of the rangefinder; the status display is connected to the local area network through the network port;

[0059] The second serial port circuit is used to transmit the RS232 serial port signal decoded by the second serial port server to the second single-chip microcomputer circuit;

[0060] The second single-chip microcomputer circuit is used for decoding RS232 serial port signals and controlling the corresponding indicator lights and buzzer circuits to work according to the decoded signals.

[0061] Specifically, the second single-chip microcomputer circuit decodes the RS232 serial port signal and controls the corresponding indicator light to light up according to the decoded signal, wherein the green light indicates normal, the yellow light indicates standby, and the red light indicates shutdown. When the yellow and red lights are on, the buzzer will sound an alarm, thereby realizing real-time monitoring of the LDB102 rangefinder equipment.

[0062] The indicator light and buzzer circuit comprises: an indicator light and buzzer connection port;

[0063] In the indicator light and buzzer circuit corresponding to the standby state and the shutdown state, the buzzer connection port is connected to a buzzer.

[0064] It should be explained that when the rangefinder is in normal state, it does not need to sound an alarm, so the indicator light and buzzer circuit corresponding to the normal state do not need to be connected to the buzzer connection port (such as Figure 4 An external buzzer can be connected to OUT1 to OUT6 in the circuit.
