[ background of the invention ]

The elevator counting timer is a device for recording the lifting times and the working time of an elevator, is used for recording the running condition of the elevator and is convenient for elevator maintenance, and the schematic block diagram of the elevator counting timer is shown in figure 1: the intelligent clock comprises a key 1, a microcontroller 2, a display screen 3, a battery 4, a clock reference 5 and a wiring terminal 5. In practical use, the elevator sends a level signal to the counting timer every time the elevator rises or falls, when the elevator counting timer receives the level signal sent by the elevator, the counter is increased by 1 time every time the elevator receives the level signal, the time length of the sent signal is recorded at the same time, the time length is recorded in the timer by taking seconds as a unit, and counting and timing data are displayed through the display screen 3. In practical engineering, the problem that the time counter cannot be clocked due to the abnormality of the time counter battery 4, the clock reference 5, the connection terminal 6 and the like is inevitable in the assembly and practical use of the time counter, and therefore, whether the related functions of the counting timer are normal or not needs to be detected.

The monitoring principle of the elevator timing counter in the prior art is shown in fig. 2, and comprises a power supply 7, a switch S1 and an elevator timing counter 8 to be detected, wherein the detection process comprises the following steps: the circuit is connected according to the figure, the manual on-off of the switch S1 is used for simulating the signal of the elevator to send a timing counter to the elevator, the switch S1 sends a signal once, the value of the counter is increased by 1, and meanwhile, the timer records the length of the sent signal in seconds. The result of the test requires a manual check to see if the number of times the switch S1 is turned on and off is consistent with the number of times displayed by the counter, and a stopwatch to see if the time of turning on is consistent with the time displayed on the timer, if both are consistent, the test is passed, and if both are inconsistent, the test is not passed. The detection is not only low in efficiency, but also only can detect one elevator timing counter 8 to be detected at the same moment, and human errors often occur, so that the test effect is influenced.
