る。Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to an information transmitting apparatus for construction machines, and more particularly to an information transmitting apparatus with reduced communication frequency. 2. Description of the Related Art In a construction machine such as a hydraulic excavator, operation information of the machine is stored in a memory in a controller, and the operation information is managed using communication means such as a satellite communication, a mobile phone, or a PHS. 2. Description of the Related Art There has been known an apparatus which wirelessly transmits information to a center and remotely manages machine information.
When transmitting the operation information of the machine, the following transmission timing is conceivable. (1) Sent when the key switch of the machine is turned on. (2) Sent when the engine is started. (3) A separate transmission switch is provided, and transmission is performed when the switch is operated. [0003] Of the above-mentioned operation information transmission timings, in the case of (1), transmission is frequently performed in a use situation where a key switch is turned on and off many times. Communication costs increase. Similarly, in the case of (2), in a use situation in which the engine is repeatedly started and stopped many times, transmission is frequently performed and communication costs increase. In contrast, in the case of (3), the number of transmissions can be suppressed, but the switch must be operated each time, and the operation is complicated. Further, a clock function may be provided in the controller or the transmitter of the machine, and the setting may be made such that the transmission is performed only once a day by operating the clock function. However, in order to make use of the clock function, it is necessary to always connect the power supply even when the machine is not operating, and there is a possibility that the battery will run out when the vehicle is stopped for a long time. [0005] Therefore, there arises a technical problem to be solved in order to make it possible to perform regular transmission while suppressing the transmission frequency, regardless of the use condition of the machine. The purpose is to solve. SUMMARY OF THE INVENTION The present invention has been proposed to achieve the above object, and includes means for detecting operation information of a machine and means for wirelessly transmitting the operation information to a management center. In a construction machine information transmission device having a means for measuring the operating time of the machine, a means for adding the measured operating time, and a non-volatile memory for storing the added operating time, When the power of the machine is turned on, first, the added operation time stored in the non-volatile memory is read and compared with a preset time, and when the added operation time is larger than the set time, The operating time added after wirelessly transmitting the operation information of the machine to the management center is reset. On the other hand, when the added operation time is smaller than the set time, the wireless transmission of the operation information is not executed. Earn Provided is a construction machine information transmission device configured to continue measuring and adding working hours, and to turn off the power after storing the added working times in a non-volatile memory when a key switch is turned off. It is. An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a block diagram of an information transmission device 10, a unit 11 for detecting operation information of a machine, a unit 12 for measuring the operation time of the machine, and a key switch 13.
Are connected to the controller 20. The controller 20 comprises an arithmetic processing unit 21 such as a CPU, a non-volatile memory 22 as a storage unit, an IO (not shown), and the like. Means 23 for adding the operating time of the machine, and means 24 for comparing a predetermined set time previously stored in the nonvolatile memory 22 with the added operating time. And controller 2
In accordance with a control procedure described later, 0 wirelessly transmits machine operation information data from the transmission means 25 to the management center, or stores the added operation time in the nonvolatile memory 22. When the machine is powered on, the operating information detecting means 11 detects the operating information of the machine, and the operating time measuring means 12 measures the operating time. The operation information and the operation time data are read into the arithmetic unit 21 of the controller 20, and the operation time is added by the operation time adding means 23. As shown in the flowchart of FIG. 2, first, in the first case after the power is turned on,
The added operation time (accumulated time) is read from the non-volatile memory 22 (Step 1 → Step 2), and the preset time and the accumulated time are compared by the operation time comparison means 24 (Step 3). ). At this time, if the accumulated time is longer than the set time (including the case where the accumulated time is equal to the set time), the controller 20 transmits the operation information data from the transmission means 25 to the management center (step 4), Thereafter, the accumulated time up to now is reset (step 5). If step 5 is reached, or if it is not the first time in step 1, or if the accumulated time is smaller than the set time in step 3, the process jumps to step 6 and the operating time is reduced. Addition and accumulation (step 6). When it is detected that the key switch 13 has been turned off (step 7), the accumulated time is stored in the nonvolatile memory 22 (step 8).
Power off the machine (step 9). For example, the operating time of a machine per day is 8
If it is time, if the set time is set to 16 hours, the operation information data is automatically transmitted only once every two days. Thus, the transmission frequency of the operation information of the machine is suppressed, and the communication cost is reduced. The present invention can be variously modified without departing from the spirit of the present invention, and it goes without saying that the present invention extends to the modified ones. According to the present invention, as described in detail in the above embodiment, the added operating time is compared with a preset set time, and the added operating time is longer than the set time. In some cases, the operating information of the machine is wirelessly transmitted to the management center, and when the operating time is shorter than the set time, the wireless transmission of the operating information is not executed. Then, at the time of the key switch off operation, the power of the machine is turned off after the added operation time is stored in the nonvolatile memory. Therefore, regular transmission is possible while suppressing the transmission frequency, regardless of the use condition of the machine.
